Beauty, durability and functionality interior door will be ensured if the assembly and installation of the box is done efficiently. You can assemble and install the frame yourself if you have the skills and desire to save money.

Today, interior design products are delivered assembled, but not always. Made to individual sizes and assembled with your own hands, it fits more accurately into the opening. In this case, the assembly and installation of the box is carried out as carefully as possible in compliance with the rules and technology. This is the only way to achieve the absence of gaps, cracks and sufficient strength.

Door frame requirements

To assemble and install a door frame correctly, the following conditions must be met:

• The dimensions must correspond to the dimensions of the opening (2-3 cm smaller).
• The slats are selected with a thickness of less than 4-5 cm from dry and strong material without defects.
• The racks must be placed vertically.
• The ceiling must be strictly horizontal.
• The frame must have a thickness that allows the platbands to be laid on the frame and wall without distortion.
• Width and thickness are adjusted by installing extensions.

A standard interior door frame has dimensions of 207 cm by 80 cm. The width may vary depending on the purpose. In bathrooms, the opening is often 70 cm wide.

The door frame must obtain strength that ensures the functionality of the leaves attached to it using hinges, without deformation. To seal in the bathroom and toilet, you need to install a threshold. It is not needed in the kitchen, but leaves a gap in the canvas for ventilation.

Design Features

The box is attached directly to the opening. The canvas is hung using mortise hinges, which must support its weight.

The structure is made of wood or metal profile. Sometimes it is made from pressed, composite materials or plastic. The shape of the frame always completely follows the outline of the opening. In arched structures, sometimes only a box without canvas is used.

The interior door frame consists of the following elements:

• Frame. These are two side and two or one horizontal posts made of bars, tightly connected at the corners. The bars have a box profile. They are often equipped with a recess for the door leaf. Exist different ways the connections of these elements are “tongue and groove”, at an angle of 90 and 45 degrees.
• Platbands. They are used to decorate and hide gaps between the wall and the frame. Three strips are installed - two on the sides and one on top, connected to each other at an angle of 45 degrees.
• Threshold. It is a bar up to 2 cm high, which is installed instead of the lower horizontal beam of the frame and frames the structure from below for better insulation of the room.
• Seal. Not used on all designs. Most often on balcony doors and in bathrooms.

Working tools and opening preparation

To assemble and install, you need to prepare a tool. You will need:

• Level.
• Plumb.
• Hammer and drill.
• Screwdriver.
• Saw.
• Miter box and set of chisels.
• Square
• Screwdriver Set.
• Dowels, screws and anchors.
• File and sandpaper.
• Roulette.
• Clamps.
• Plane.
• Hammer.
• Wooden slats.
• Polyurethane foam.

For subsequent finishing, you need to prepare a paint brush, trowel, putty and appropriate containers.

Assembly and installation begin with preparing the opening. Without determining its exact parameters, it is impossible to understand what dimensions the box should have.

Installation is carried out only on silt-bearing reinforced surfaces, that is, the opening must be cleaned to a solid base. This is done mechanically. If necessary, it is leveled using construction methods - brick laying or sealing with mortar.

Often the construction of a frame from a profile is used, followed by cladding with gypsum plasterboard or other available material. Sometimes the opening is adjusted to the dimensions of the existing structure - it is simply broken.

The wall at the opening must be checked for verticality. Then the measurement is performed. First the width, then the height of the opening. It is recommended to do this at several points. The lowest values ​​are selected for the required parameters. Also taken into account is the gap size - 2 cm. Once the dimensions of the box are determined, it can be manufactured and assembled.

Box assembly

The box is assembled from wooden beam, having a special profile. The assembly has the following order:

• First, two beams are cut 3 cm long less than the height of the opening.
• The timber for the ceiling is cut off. The length should be 3 cm less than the width of the opening.
• The bars are being adjusted. There are three connection methods: tenon, baguette (at an angle of 45 degrees) and the overlay method (at an angle of 90 degrees). The last method is the simplest, but the first two are the most reliable and beautiful. The angle is formed with a miter box. It is important to consider that the length of the smaller (lower) side of the upper crossbar after cutting should have a width that is 7 cm greater than the width of the canvas.
• Next you need to put everything together. The side posts are connected to the ceiling. The process is controlled using a square - the connection must be strictly at a right angle. A thin soft gasket is laid between the elements, after which the bars are tightened with clamps. The structure is checked for correct angles, after which holes are drilled in the racks for self-tapping screws 4 mm thick.

Additionally, before joining, it is recommended to cover the sections with wood glue. A jumper is installed between the posts to prevent them from moving. First, one corner is tightened, and then the second. For greater strength, a wooden dowel is used, a hole (diameter 12 mm) for which is drilled in the center of the joint perpendicular to the cut. The dowel is coated with glue and hammered.

Door frame installation

When the box is assembled, installation can be done. The operating procedure is as follows:

• Installation begins from the threshold, if planned. A wooden plank 2 cm thick and the length of the opening is attached to the floor. This is done with dowels
• Then the installation of the finished box begins. Fastening is done with dowels or anchors. To do this, the box is inserted into the opening and three small diameter holes are drilled in the side posts on each side. About 15 cm from the ends and one in the middle. At the exit points on the wall of the opening, the entry points of the anchors are marked. Two symmetrically located holes are made in the lintel.
• The box is removed, and holes with a diameter for fasteners (8 mm) are drilled in the walls.
• The box is inserted again, leveled with a plumb and level check and screwed. Correction of angles and planes is carried out using wedges.
• The screws are tightened, and their heads are completely recessed into the bars.

In the video you can see in a simple way builds:

When the installation is completed, all that remains is to finish the opening. This operation is performed in the following order:

• The cracks are foaming.
• Excess foam is cut off. If necessary, putty is used, which is sanded after drying.

• Extensions and trims must be installed so that one edge of the plank falls on the frame, and the other covers a section of the wall. Installation is carried out using liquid nails or small nails without heads.

If everything is done correctly, the interior door frame will last a long time and reliably. The doors will work without jamming and will retain their original appearance for many years.

When purchasing a new door, the buyer receives a far from complete structure for installation. It does not have places to install hinges, and the locks are not embedded. The buyer has an inevitable question - how to collect

You can use the services of professionals or install the structure yourself. To do this, you need to prepare tools and study the features of the technology.

Doors on the market are mainly sold complete with a frame, but sometimes they need to be matched to each other.

For the most part, new doors do not fit into old frames, either in size or style. In this regard, it is necessary to completely change the previous design.

Selection of door frame material

Nowadays, the market is dominated by products with an impressive appearance and a low price, for example, made from MDF - a composite of compressed fibers.

How to assemble a door frame from MDF so that it lasts no worse wooden structure? The new material has many advantages, but here it is important to dwell on the disadvantages. Despite its great strength, the box may become deformed if it is heavy. In addition, in a humid environment, MDF panels can peel off and also swell, leading to disruption of the geometry of the opening.

Despite the shortcomings, affordable cost, good mechanical properties and a wide range of MDF parts make them a priority even when completing premium doors.

Required Tools

Before assembling the door frame, you should first prepare the tools:

• hammer;
• set of chisels;
• roulette;
• square;
• or with fine teeth;
• plumb level;
• dowels, screws, hinges;
• miter box - a tool for making cuts at certain angles;
• screwdrivers.

The work is greatly facilitated if you have a power tool: a screwdriver, a jigsaw, an electric drill, a hammer drill, a router.

Preparing the doorway

It is important to choose the right door according to the width of the opening, so that later there will be less work on fitting. The minimum gap should be at least 15 mm on each side.

Before installation, check the evenness of the opening. It is measured in several places vertically and horizontally.

How to assemble the door frame of an interior door if the opening is too large? To do this, planks of the required width are packed around the perimeter or the space is filled with bricks.

Other options are glazing the opening, making a frame from wood or metal and covering it with plasterboard.

Door frame components

The box is made of timber and consists of fragments:

• looped timber and porch;
• lintel (top beam);
• threshold.

Thus, in order to assemble a door frame (it is equipped with a threshold only for a heavy leaf, which is mainly used at the entrance to an apartment), it is necessary to correctly connect its component parts.

Thresholds are rarely installed for interior doors.

Door frame assembly methods

Assembly is carried out extremely carefully so as not to damage the decorative coatings. Even one minor chip or scratch spoils the appearance of the structure.

To install doors in frames, hinges are required. In interior designs, two are enough, and for the entrance, a third is often installed.

The main difficulty in assembling the box lies in the correct execution of cuts and connecting the horizontal beams with the vertical ones. Their profiled structure creates difficulties for beginners. The installer must fit all elements exactly to size. Before assembling the door frame, you should choose an installation technology. The beam is attached in several ways.

Tenon connection

The most durable and reliable, but at the same time the most complex, is the tenon joint. To do this, grooves and ridges are made at the junction of the beams along their thickness. Here you also need the ability to use it. The connection is made without fasteners, but many craftsmen make additional reinforcement with galvanized nails.

It is not so important on which part to make a groove or tenon. In any case, a rigid connection is ensured.

A router is a tool for professionals and it is not practical to purchase it to install even several doors. When we assemble the door most in an accessible way is docking at an angle of 45 0 or 90 0.

Even a beginner can do the assembly at right angles if he performs all the operations correctly.

How to assemble an interior door frame with a joint 45 0

At the junction of horizontal and vertical beam cuts are made. Measurements are taken several times in advance so as not to make mistakes in the calculations. It is especially necessary to adjust the horizontal beam precisely in order to correctly select the gap of 3-4 mm and the width of the door. The racks can subsequently be sawed off from the bottom after assembling the box, since they are made with a margin of length. After cutting, the surfaces to be joined are leveled with a chisel.

The timber is usually fastened with self-tapping screws at an angle of 45 0 . To prevent the wood from splitting, holes are made under them with a drill, the diameter of which should be smaller than that of the self-tapping screw core. The drilling depth is made less than the length of the fastener so that the connection is reliable. One joint requires two screws on one side. You can add another one in the middle, on the other side of the corner.

How to assemble a door frame with a docking 90 0 yourself

The assembly method is best for beginners. First of all, the door leaf is measured for compliance rectangular shape. It is often observed that one of the sides is slightly different in size from the other. This deviation must be taken into account when sawing the racks. The cuts from the ends of the timber are also checked, which must be strictly at an angle of 90 0. Workpieces may arrive from the factory with an uneven cut.

The connection of the horizontal strip with the vertical ones is also made with self-tapping screws.

Checking the correct connections

The test is carried out by placing the box on a flat horizontal surface and placing the door leaf on top of it. If it fits in with a small gap, then the assembly was done correctly.

The lower ends of the racks are filed down, as they should rest against the floor. The horizontalness of the floor covering is preliminarily checked doorway. Deviations should be taken into account when sawing off the posts.

Important! The blanks are cut from the veneer side to prevent its peeling.

Installing hinges

Before that, you need to choose the side where it will open. Depending on this, loops of a certain type are selected - right or left. The fabric for fastening the hinges is chosen to be more massive, without defects and cracks. The location of their installation is marked at a distance of 15-25 cm from the door end. The canopies are separated into a large part for the frame and a small part for the door leaf. Then the loop is applied to the end of the door and outlined with a pencil, and then with a knife. The markings on the box are done in the same way. In this case, the door leaf is placed against the frame and the marks for the hinges match.

The edges of the door leaf and hinges are aligned, avoiding distortions. The hinges should face the direction the door opens. When marking, it is unacceptable to confuse the top and bottom of the door. This determines how it will be installed after securing the hinges. If the door has glass, their location should also be taken into account.

Using a chisel and hammer, cut out a place for the hinges to a depth of 3-5 mm so that they fit flush with the wooden surface. Fittings for fittings are made with extreme care and precision. Then the loops are applied, the screws are marked and screwed in. The marks should coincide with the centers of the holes so as not to split the wood when screwing in the fasteners. To prevent the loops from tightening with self-tapping screws, the pencil marks are additionally marked with an awl.

By applying a ruler, the correct fit of the loop is checked. When protruding, the platform underneath it deepens, but not more than the required level. If the hinges are installed correctly, the doors should open 180 0. The load on the door should not exceed the specified value. Usually it is 50 kg.

Installing a frame in a doorway

The work does not end with the points describing how to properly assemble a door frame. It still needs to be installed so that the door opens and closes well. To do this, the box is carefully placed in the opening and temporarily secured with pieces of packaging cardboard or polystyrene foam. The level checks the verticality of the loop beam. Then wooden wedges are cut.

They are installed under the hinges. These parts are also clogged in the upper corners. To prevent the box from moving, two wedges are driven in from opposite sides with sharp parts overlapping each other. The positions of the sidewall and lintel are checked with a level, since displacements are possible during wedging. The box should be level with room wall. The wedges should not protrude outward.

Questions of how to assemble and install the door frame, as well as hanging the door leaf, are resolved together, since everything is a single structure.

The door frame is attached to the wall with dowels at the hinge locations. Wedges are also located there to prevent deformation of the timber. The pretend side is not yet exposed.

To make the exposed elements of the box more stable, they need to be partially foamed. The surfaces are pre-cleaned and moistened with water, which increases the adhesion of the foam by an order of magnitude.

Hinges are attached to the door leaf, after which it is installed on the lining in the doorway. Then the door hinges are attached to the frame beam: first from above, then from below.

The door is closed and the porch is set using wedges. When all the gaps are set, you should foam the box around the entire perimeter. It is recommended to install spacers in it to prevent swelling of the parts.

Conclusion

If you have the necessary tools, you can install the doors yourself. To do this, the most important thing is to figure out how to assemble the door frame. If you perform all installation operations correctly and consistently, everything will work out.

A door of a new design was purchased and the owner looks in bewilderment at the door without fittings and the necessary inserts.

If you want to do without craftsmen for assembly door frame with your own hands was successful, you need to familiarize yourself with this technological process.

Only correct installation door design will be responsible for its reliability and beauty. Determining the size of the doorway and proper assembly of the necessary elements determines how long and effectively the door will serve in the house.

Important points that masters pay attention to before starting work:

• correspondence of the horizontal and vertical axes of the box with the elements of the wall and canvas
• take into account the state of the microclimate in the home
• comply with GOST requirements
• select parts for fixation in accordance with the weight of the structure
• the product is fixed in the correct relationship with the load-bearing elements with appropriate reliability
• pay attention to the use of polyurethane foam, its ability to expand at the moment of hardening

The door frame is fixed according to the following schemes:

• with making cuts at right angles, which are performed with a saw shaped with fine teeth; with special care, for this you need to have knowledge and ability to process wooden parts
• installation at an angle of 45 degrees. carried out using a miter saw and miter box

To carry out the installation steps, you need to know where to start assembling the door frame, step-by-step instruction explains the list of necessary components for commercial products.

Need for tools and materials

Acquisition necessary details contains the following elements:

• door leaf
• screws and dowels
• bars for vertical and horizontal
• platbands
• anchor bolts
• iron hanging strips
• wedges according to the width of the openings
• polyurethane foam

The design of the door frame is an ordinary frame of vertical hinged and hinged jambs. The purpose of loop beams is to carry loads from the webs. In addition, there are horizontal box jumpers. The upper elements are called lintels, the lower ones - thresholds.

Not every consumer installs thresholds in their doors, since they are optional and serve to hide cracks or get rid of drafts, and also protect the neighboring room from moisture penetration. If a hole appears near the floor and the threshold hides it flooring. The side of the door frame at the time of construction of a new house is performed before installation begins finishing materials lower.

Availability of detailed connections

Despite the structural simplicity of the door frame, they correct work depends on the competent assembly of the connections of individual parts in order to obtain a single closed circuit if there is no lower jumper.

In this case, the bars are fixed together using the following methods:

• Tenoning is a durable but labor-intensive process. To perform it you will need special skills and certain tools.
• Baguette fastening is performed using studs and screws; detailed trimming at an angle of 45 degrees will be required. At the same time, if a door frame is assembled from MDF, chipping of the materials and sloppy external seams is possible.

Making connections using right angles implies the need to cut a quarter of the structure, but it has been proven in practice that the method is the most reliable, simple and effective for any door structures.

How to assemble a box

Beginning masters choose the most easy way, join the parts at right angles. To begin the procedure, you need to assemble all the structural elements on a horizontal platform. A floor surface covered with any available material or shifted ones will do.

The technological process consists of the following working order:

• Lay out the bars facing the front, align the door plane with the future frame. Regardless of the chosen connection, the elements consist of a loop, a false jamb and a lintel piece.
• The crossbar related to the lintel frame, if it is installed in an opening made of foam concrete or brick, must be wider in width than the frame, this increases the load-bearing capacity. Then they determine where to attach the jambs to the lintel. From the middle of the lintel beam, equal measures are taken on both sides.
• Form equal gaps between the frame and the door leaf on all sides using various gaskets.
• If necessary, the points for cutting are determined.
• The crossbar is being manufactured.
• An awl or scalpel is used to mark the false profile area for further removal to form an area for connecting points. Careful cuts or cuts are made according to the marks.

Installation actions are carried out with special attention. Allowing minor errors in the dimensions of the beams masks other elements and appears unaesthetically in the false areas. The formation of excess can be removed with a chisel if the recess is cut out correctly.

The next assembly stage consists of the following actions:

• The pieces of bars prepared with the necessary cuts are laid out where the gaps on the canvas are marked with gaskets. Mark the places where the loops will be placed. If standard is selected, add the upper gap to this size and determine a point equal to a distance of 2.03 m from the intersection of the jamb and the lintel.
• Hinged sashes are screwed onto the corresponding beam, a sharp object is used to mark the boundary along which material will be removed and traces will be made at the points where mounting holes will be drilled. Based on pre-made measurements and markings, selective actions are carried out on the section of the bar. The recess should be equal to the thickness of the loop element.
• After the shapes for the hinged sashes are formed, they are placed in the prepared recesses and screwed with screws.
• The work will be completed by checking the correctness of all fastenings made, fixing the crossbar element with the posts.

Only the accuracy of measurements, checking the level for compliance of all parts, the correctness of their fixation without distortions, will provide the opportunity for good operation of the whole.

Making a frame from MDF

Many consumers choose to install door frames made from composites based on pressed fibers. The technological process of this design differs in some respects in relation to alternative options.

The characteristics of such commercial products include the following points:

• The products are based on elements made using cellulose fibers pressed and impregnated with glue. Strength and density are ensured by special technological processes.
• All parts are made by giving them shapes, so that they fit tightly to the door leaves.
• The surfaces of the parts are made with decorative coating protecting them from moisture penetration and adding attractiveness appearance.

The different designs are divided into the following:

• With application of paper segments. Profiled fragments are produced with textured paper pasted over them and a varnish coating. Such products, even with a protective layer, do not protect the product from defects after friction or wetting.
• Parts are laminated; such products are most in demand in construction markets. They are distinguished by their attractive appearance and long service life. Decorating with film makes surfaces moisture resistant and preserves color.
• The finishing is done with natural wood veneer. These boxes are similar to those made from solid wood, differing only in their short service life, since in a humid environment or temperature changes the glued part peels off.

In practice, there are examples when, when assembling parts, the door components contain a connection of a wooden beam with the fastening of a stamped profile part.

Advantages of pressing

The choice of many owners of MDF doors and frames is due to the following advantages:

• Providing small load effects on load-bearing elements due to the lightness of the materials
• products are manufactured with a homogeneous structure, which is the reason for their integrity; in addition, the stability of fastening elements is noted
• development technological processes in the field of decoration produces products with imitation of expensive natural finishes

The disadvantages of cheap panels include:

• poor resistance to direct contact with water, swelling and deformation of geometric parameters occurs
• the change in shape is caused by the installation of a thin door frame and a heavy door leaf
• requires careful handling regarding mechanical damage
• installation contains labor-intensive procedures

If we compare MDF and wooden boxes, of course, natural material takes precedence on all sides.

Even if it has lost its original appearance over time, it can be easily restored with the help of repair and restoration projects. But for consumers, their ability to pay often comes first.

The materials and tools for carrying out the work are no different from the above proposed list except for the MDF elements themselves. The main condition for assembly is the formation of a rectangle.

Work must be carried out on a flat surface on which:

• laying the door leaf
• parts of vertical risers are placed on the side sections
• carry out cutting of workpieces, adjusting the height with the corresponding 3mm. gaps at the top and bottom, if a threshold is provided
• the jumper at the top is also cut according to the width and side gaps

Then they move on to the connecting actions of the jumper and vertical riser. As soon as the assembly is completed, it is necessary to check whether a structural distortion has occurred.

How to install a frame in an opening

A door frame assembled from any material must be correctly inserted into the opening intended for it, so that it performs its functions for a long time without creaking or jamming.

To do this you need to work as follows:

• Carefully move the assembled structure to its intended location and temporarily secure it with polystyrene foam or packing cardboard. Using a level, the verticality of the surface is checked with the side where the hinges will be attached. The strength of the structure is necessary so as not to disrupt the evenness of the installation, so fixation is inserted into the gaps using wedges. They are made from wood waste.
• Installation for such fastening is carried out from the bottom of the hinge arrangement, there will be fastening with dowels or. The stakes are driven into the upper corners to achieve a stable position for the entire frame. The spacer wedges are driven in one at a time on each side, and try to align them with each other with the cut parts. On one side, the installation of extensions is carried out, the other is carried out by leveling the door frame with the wall surface.
• The door frame is fastened using holes prepared for fasteners to install hinges. Wedging must be present there so that deformation moments do not occur at the moment of screwing in the screws. In this case, the pretend side is slightly secured and not brought to the final stage. In order not to knock down the dimensions, the installation of this part occurs after the door leaf is installed.
• For stability, foam is applied to the gaps.
• All door hardware is installed.
• Place a gasket under the canvas and screw on the looped parts one by one, starting from the top.

After completion, close the door completely, using spacers, and finish installing the door part. After this, they begin to apply foam around the entire perimeter. Experts recommend using spacer stakes; only they will ensure reliable stability and prevent skewing of the risers.

You should not increase the number of fasteners, since the door leaf acts under its load with the help of hinges, so the main attention is paid to these places.

Excess hardware can create the appearance of unnecessary holes and only under the hinged base will the fasteners reliably hold, which must be screwed tightly. You cannot hide unreliable screwing with foam; it cannot get rid of the problem.

Do-it-yourself door installation is shown in the video:

IN full set The door block includes the leaf, frame and hinges. It can be difficult to purchase a ready-made complete set, so there is nothing left to do but make a door frame with your own hands from profiled timber or entrust this task to specialists. The box, most often, has to be selected separately, and it is not a structure ready for installation, but several elements that need to be adjusted in accordance with the size of the opening, the necessary cuts made and assembled. It is not so easy to assemble a door frame with your own hands, so in addition to tools, it would be nice to have at least a little carpentry skill.

Wood MDF

The frame serves not only as a frame for the door leaf, but also as a load-bearing base. The strength of the entire structure and its durability depend on the quality of the material and installation of the product. The choice of material depends on the purpose of the door and the material of the leaf itself. Metal-plastic and metal doors They are usually supplied fully equipped, so we will consider only those cases where the door frame has to be manufactured independently. As a rule, in this case we are talking about two types of material: wood and MDF.

• Natural wood has different densities and is sorted into soft and hard. The cheapest and most popular product is pine, but when it comes to installation entrance doors, then you should focus on a harder and more expensive type of wood, for example, oak. It will ensure durability, strength and reliability of the structure.
• MDF is used exclusively for interior doors. If you are going to assemble a box from this material, you should treat all cut edges with nitro varnish to ensure protection from moisture.

Equipment and standard sizes

The door frame consists of several slats: two side, top and bottom, if the design includes a threshold. If the depth of the doorway exceeds the corresponding parameters of the timber, your kit must be supplemented with extensions that will increase the depth of the box.

Standard door block sizes vary in width and height. The correspondence of the parameters of the door leaf, block and opening is indicated in the table.

Do-it-yourself door frame assembly is carried out taking into account the following points:

• There should be a technological gap of 3 mm wide between the inside of the frame and the door leaf along the entire perimeter.
• The gap between the wall and the top of the box must be at least 20 mm.
• The gap between the side planks and the wall is 10 mm from each side. When installed on polyurethane foam it is necessary to increase the gap to at least 20 mm.
• The gap between the bottom of the sash and the frame or floor depends on the material and location of the structure. For dry rooms, these parameters can vary between 5–15 mm, for wet rooms, in order to ensure ventilation, - 50 mm.

Options for connecting structural elements

The main difficulty in assembling door frames is the process of connecting individual elements. The joining of horizontal and vertical strips of the product can be done in two ways:

1. I washed it down at an angle of 45 degrees. This process is best done with a miter saw, but in the absence of one, a miter box will do.
2. At a right angle of 90 degrees. To cut the workpiece you will need a saw with fine teeth.

The joining of the planks is carried out using tenon joints or galvanized self-tapping screws. The figure shows options for tenon joints, which clearly show how to assemble the door frame yourself to ensure high strength of the joints.

When calculating the parameters of the length and width of the profile slats, it is necessary to take into account that the length of the tenon should be equal to the thickness of the box beam. The tenon joint provides sufficient strength to the finished structure, but if desired, additional reinforcement of the joints can be made with zinc-coated nails.

Door frame assembly process

Let's look at how to properly assemble a door frame . As a starting material, we will need profiled timber made of natural wood or MDF.

The box is assembled in the following order:

Step-by-step installation process

To secure the assembled frame in the opening and install the doors yourself, you must perform the following steps:

Tip: Before foaming, you need to clean the surface from dust and moisten it with water from a spray bottle. These measures can significantly increase adhesion.

Another important condition To avoid disturbing the geometry of the frame during the installation process, use spacer wedges that correspond to the width of the box and are inserted across it.

The final stage of installing the frame and door is decorative design opening with platbands.

One of the final stages of renovation is the installation of an interior door. This process is quite complex and requires special attention to detail. After all, even the slightest mistake can render the entire structure unusable. If you follow all the rules, the process of assembling the door frame will not be difficult.

Calculation of doorway parameters

Before installing the door frame, you should prepare the room. The walls must be leveled and plastered. You also need to decide what type of finished floor will be installed in order to cut the box to the desired height. It is important to maintain the verticality of the walls, since after installing the door their curvature will be evident.

Having chosen the doors, you need to figure out the size of the opening. Specialists can adjust the openings by installing a plasterboard partition on the metal profile. However, it is very difficult to match the dimensions of the box with the existing parameters of the opening. And if you do not carry out all the calculations, then the risk that the door block will not fit increases, and then it will be necessary to eliminate large gaps and re-glue the wallpaper.

To assemble the door frame, the following parameters should be determined:

Door width and height;

The width and thickness of the door block;

Threshold height (if any);

Width of platbands.

The width of the opening can be calculated by adding 15 mm to the width of the gap on each side. When calculating the height, the threshold value is taken into account. If it is absent, take into account the gap formed between the bottom of the door and the floor.

Door frame assembly

After all the required parameters have been found, we begin to connect the elements of the door frame, which can be done using several methods.

A 45 degree connection involves sawing off pieces on bars at an angle of 45. On the horizontal crossbar, cuts are made on both sides. It is important to ensure that the length vertical racks was the same. You can find it as the sum of the width of the door leaf, the thickness of the vertical boards and the spaces between door block and canvas. The beams are connected using self-tapping screws, which are screwed in at an angle of 45 degrees. It is recommended to carry out work on a flat surface, such as the floor.

With another method, the beams are connected at right angles. In this case, the boards are simply stacked on top of each other. This method is the easiest, however, before fastening, you should saw off the doorway of the box.
