Construction frame houses is gaining more and more popularity. Characteristic application of this technology – reduction in cost and efficiency of work. Due to the variety of materials on the market, the question arises about the use of I-beams in construction. The material is a pair of timber (shelves) equipped with glued-in milled plywood of a given thickness. According to calculation methods for the resistance of materials, I-beams wooden beams are characterized by optimal distribution of bending load, which is a necessary condition construction requirements for load-bearing and other structures. How practical are houses made from I-beams, what are the advantages and disadvantages of the material and the scope of application of piece products - this is worth knowing before planning the development of an individual cottage.

Advantages and disadvantages of using I-beams in frame construction

Possessing a lot of advantages, I-beams are one of the most durable and at the same time practical materials. In particular, professionals emphasize the following advantages:

• The reduced degree of bending under load and increased strength characteristics make it possible to use the material for load-bearing beams for arranging frame-type structures.
• Wood has a reduced weight compared to others piece materials, which means a lighter foundation is shown, which is a direct cost saving.
• The uniformity and stability of the shapes of the beams facilitate installation and speed up the construction time.
• The adhesive base used to connect the beams does not contain harmful substances, which allows us to call the I-beam an environmentally friendly material.
• The lightweight mass of the elements makes it possible to carry out all construction operations with your own hands.
• Carrying out engineering systems carried out quickly and without compromising the load-bearing capacity wall panels.
• A high energy saving rate will reduce coolant costs.
• An expanded range of sizes will help you build a house of any size.
• Impregnations against moisture and fire will ensure the resistance of the material to harmful phenomena.
• The absence of deformation will allow you to maintain the original shape of the structure for many years of operation.

As for the disadvantages, they also exist:

1. When using low-quality glue, after 1.5-2 years the I-beam “looses” and walking on such an overlap becomes dangerous.
2. The use of poorly dried timber for the manufacture of I-beams risks deformation of the material during further drying.

Important! A house made of an I-beam requires thoughtful ventilation, otherwise you will end up with a “thermos” in which it will be unbearably hot in the summer.

The I-beam allows for all communications in the platform. Elements up to 300 mm in size allow drilling holes up to 150 mm, and side inserts made of OSB will serve as additional reinforcement. Such manipulations are impossible with a regular board. Making floors from I-beams is not only possible, but highly recommended. It is recommended to use beams for both small and large spans (in some cases, an I-beam is laid for spans of up to 7 meters). Recommended dimensions: 300 beam with 68 mm flange. On such a platform you can make a concrete screed to strengthen the floor.

As for the application features, the indicators are as follows:

• If the I-beam lies as the main supporting structure, then the total weight of the building will decrease, which will reduce costs general installation and foundation work.
• Floors made from I-beams made of wooden beams have high strength indicators, which complies with the norms and requirements (SNiP for building materials). The use of elements on areas of any size will minimize typical problems: bending, cracking, shrinkage.
• I-beam interfloor ceilings, if installed in accordance with the requirements, will last for a very long time and will not lose their original properties. quality characteristics.

Important! The use of an I-beam in the manufacture of a frame box threatens with an unjustified increase in price and thickening of the wall panels. For example, minimum size beams are 240 mm, while the insulation will be in 5-6 layers - this will provide warmth, but at high financial costs.

I-beams of wood, of course, have a reduced cost compared to materials of similar quality characteristics, but building a complete house from this material may not be profitable. But if you make the I-beam yourself, the costs will be significantly reduced.

How to make an I-beam with your own hands

Making the material is not the most troublesome task. Having minimal carpentry skills, tools and patience will reward your efforts and result in real savings. Expert calculations confirm that making an I-beam with your own hands can reduce construction costs by at least 20%. And given that the scope of application of the I-beam is not limited in any way, the material will be useful not only for arranging all the floors in the house, but also for building a “box”.

The manufacturing technology is as follows:

1. The main material is purchased - these are bars with a section of 25 * 35, and the calculation is made after determining the bearing load.
2. The lintel material also needs to be purchased; this is an OSB board, OSB or plywood, which is also determined by the purpose of the I-beam.
3. The groove is cut using a milling machine, a circular saw, or even a regular electric saw. But everything depends on production volumes.
4. Process the edge of the plywood in the shape of a trapezoid.
5. Using a mallet, align the plywood with the groove of the timber, having previously applied it to the length of the groove. adhesive composition. And here it’s better not to be cheap, but to buy good glue for plywood.
6. Align the parts and place them in clamps or a vice until the adhesive mixture dries completely.
7. Then repeat the entire procedure on the other side.
8. Cut the finished product into the required lengths, but first check for size compliance.

Here is a simple option for making an I-beam with my own hands. At the same time, the products are no worse than those from Intercity, a manufacturer that offers very high-quality I-beams. Construction frame house made from home-made I-beams will not cost as much as from purchased material.

A little about the Intercity material. The I-beam from this company is a truly high-quality timber, suitable for the construction of frame or frame-panel type buildings. Characterized by strength, lightness and practicality, the I-beam is inexpensive, and the company offers individual cutting of the size range. The popularity of the products is that only perfectly dried timber and an adhesive composition that is safe for human health are used for production. Therefore, having decided to build frame house from an I-beam or make floors from these elements, you can not only save significantly by purchasing Intercity products, but also be sure of a long service life. And, most importantly, the manufacturer provides a 30-year guarantee on its product, which is also important.

Scope of application of I-beam

The significant use of beams in the construction of a frame house is explained by the breadth of application of the elements. They are good for many processes:

1. Floors. Minimal deflection ensures quiet operation flooring In addition, the I-beam will provide additional rigidity to the joist elements.
2. Walls. The huge range of sizes, strength and practicality of the beams will allow you to maintain the shape of the building for a long time, lining up the panels different types: from small to large format.
3. Ceilings. I-beam roof rafters are the ideal solution to all problems. Reliable, strong and durable beams will withstand any roof for any length of time.
4. Formwork and concreting. The use of an I-beam will provide high quality concrete structures and will extend service life.

Application of I-beams in frame construction– the ability to significantly expand the variability of building forms. For example, long beams are good for buildings where a large room, dance hall. It will not be possible to create strong floors using a regular board, but an I-beam will do the job perfectly. In addition, double bending strength is a guarantee of maintaining the shape of the entire house. Some concerns that I-beams burn much faster than regular boards are minimized by the use of fire-resistant impregnations. In any case, wood needs to be processed, be it timber, board or I-beam, but the quality of beams is much higher than that of any other piece product. And, most importantly, you can make the beams yourself, and this will help to significantly reduce costs and build a house that will cost at least 25-30% less than even the most inexpensive frame project.

Walls and ceilings are the main elements of any construction.

The purpose of the ceiling is to separate floors in the house, as well as to carry and distribute the load from the components located above - walls, roof, communications, furniture, interior details.

There are several types of flooring: metal, reinforced concrete and wood.

Let us dwell in more detail on wooden floors, since they are the ones that are most widespread in private construction.

Wooden beam flooring has advantages and disadvantages

Pros:

• Beautiful appearance;
• low weight of wood;
• maintainability;
• high speed installation

Minuses:

• without special protective impregnation, flammable;
• low strength compared to reinforced concrete or metal beams;
• susceptible to moisture, fungus and living organisms;
• may become deformed due to temperature changes.

The material for wooden floor beams must have certain properties and meet the requirements:

• strength. The flooring material must withstand possible loads. The impact of both permanent and variable loads should be taken into account;

• rigidity. Refers to the ability of a material to resist bending;

• sound and heat insulation;

• Fire safety.

Types and types of wooden floors - classification

1. As intended

The main requirement for such a floor is high strength. Since in in this case, the beams will serve as the basis for the floor and, accordingly, must withstand significant loads.

Advice. If there is a garage or large basement under the first floor, it is better to make a wooden floor over metal beams. Since wooden ones are susceptible to rotting and cannot always withstand significant loads. Or reduce the distance between the beams.

Principle structural device can be independent or be a continuation of the roof, i.e. part of the rafter system. The first option is more rational, because It is repairable, plus it provides better sound insulation.

The design feature is a two-in-one effect - the floor beams between floors are, on the one hand, joists for the floor, and on the other, supports for the ceiling. The space between them is filled with heat and sound insulating materials, with the obligatory use of vapor barrier. The bottom of the pie is sheathed with plasterboard, and the top is covered with a floorboard.

2. By appearance

Wooden floor beams also differ from each other, and each type has its own advantages.

Solid (solid) wooden floor beams

For their production, solid wood from coniferous or deciduous trees is used.

Interfloor ceilings on wooden beams can be made in one piece only with a short span (up to 5 meters).

Glued wood floor beams

The length limitation is removed, since this manufacturing technology makes it possible to realize floor beams of great length.

Due to their increased strength, laminated veneer lumber beams are used in cases where it is necessary to withstand increased load on the floor.

Advantages of glued beams:

• high strength;
• the ability to cover large spans;
• ease of installation;
• light weight;
• long service life;
• no deformation;
• Fire safety.

The maximum length of a wooden floor beam of this type reaches 20 linear meters.

Since laminated wood beams have a smooth surface, they are often not sewn up from below, but are left open, creating a stylish design interior

Section of wooden floor beams

As practice shows, the cross-section of wooden floor beams has a significant impact on the beam’s ability to withstand load-bearing loads. Therefore, it is necessary to first calculate the cross-section of wooden floor beams.

IN wooden houses Logs can be used as interfloor beams for decorative purposes.

Typically used for attic floors. Round beams are highly resistant to bending (depending on the diameter).

The maximum length of a wooden floor beam made from rounded logs is 7.5 m.p.

They can be made of solid wood, or a combination of OSB and plywood. They are actively used in frame construction.

Advantages of wooden I-beams:

• exact dimensions;
• possibility of use on long spans;
• the possibility of deformation is excluded;
• light weight;
• reduction of cold bridges;
• the ability to consolidate communications;
• Possibility of installation with your own hands without involvement special equipment;
• wide scope of application.

Flaws:

• high price;
• inconvenient for insulation with slabs.

The correct selection of the cross-section of a wooden beam must be included in the design plan, otherwise the floor structure will be insufficiently or excessively rigid (an extra cost item).

Calculation of wooden floors

The distance between the wooden floor beams is determined:

Firstly, the expected loads.

The load, in turn, can be constant - the weight of the floor, the weight of the partitions between rooms, or the weight of the rafter system.

And also a variable - it is taken equal to 150 kg/sq.m. (According to SNiP 2.01.07-85 “Loads and impacts”). Variable loads include the weight of furniture, equipment, and people in the house.

Advice. Since it is difficult to take into account all possible loads, the floor should be designed with a safety margin. Professionals recommend adding 30-40%.

Secondly, rigidity or standard deflection value.

For each type of material, GOST sets its own rigidity limits. But the formula for the calculation is the same - the ratio of the absolute value of the deflection to the length of the beam. The stiffness value for attic floors should not exceed 1/200, for interfloor slabs 1/250.

The amount of deflection is also influenced by the type of wood from which the beam is made.

Calculation of floors using wooden beams

Let's assume that the distance between the wooden beams is 1 m.p. The total length of the beam is 4 m.p. And the expected load will be 400 kg/sq.m.

This means that the greatest deflection will be observed under load

Mmax = (q x l in sq.) / 8 = 400x4 in sq./8 = 800 kg sq.m.

Let us calculate the moment of resistance of wood to deflection using the formula:

Wreq = Mmax / R. For pine this figure will be 800 / 142.71 = 0.56057 cubic meters. m

R is the resistance of wood, given in SNiP II-25-80 (SP 64.13330.2011) “ Wooden structures» commissioned in 2011

The table shows the resistance of larch.

If pine is not used, then the value should be adjusted by the transfer coefficient (given in SNiP II-25-80 (SP 64.13330.2011)).

If we take into account the expected service life of the structure, the resulting value must be adjusted for it.

An example of a beam calculation showed that the beam's resistance to deflection can be halved. Therefore, it is necessary to change its cross-section.

The calculation of wooden floor beams can be performed using the above formula. But you can use a specially designed calculator for calculating wooden floor beams. It will allow you to take into account all the points without bothering yourself with searching for data and calculations.

Thirdly, the parameters of the beam.

The length of solid wooden floor beams can be no more than 5 meters for interfloor floors. For attic floors, the span length can be 6 m.p.

The table of wooden floor beams contains data for calculating the suitable height of the beams.

The thickness of wooden floor beams is calculated based on the premise that the thickness of the beam must be at least 1/25 of its length.

For example, a beam 5 m long. should have a width of 20 cm. If it is difficult to maintain this size, you can achieve the desired width by installing narrower beams.

You should know:
If the beams are stacked side by side, they will withstand twice the load, and if they are stacked on top of each other, they will withstand the load four times more.

Using the graph presented in the figure, you can determine the possible parameters of the beam and the load that it can bear. Please note that the graph data is suitable for calculating a single-span beam. Those. for the case when the beam rests on two supports. By measuring one of the parameters you can get the desired result. Typically, the variable parameter is the pitch of the wooden floor beams.

The result of our calculations will be the drawing up of a drawing that will serve as a visual aid during work.

In order to efficiently and reliably carry out the ceiling on wooden beams with your own hands, the drawing must contain all the calculated data.

Wooden floor beams - GOSTs and SNiPs

Government standards govern all aspects of the use of wood floor beams, regardless of their type or location of use.

Below is a selection of the most important documents on this topic.

Conclusion

In this article, you became familiar with the factors that influence the choice of material for constructing wooden floor beams. We also learned how to determine the cross-section and calculate wooden floor beams.

The possibility of unsupported covering of large areas significantly expands the architectural possibilities when designing a house. A positive solution to the beam issue allows you to “play” with the volume of rooms, install panoramic windows, build large halls. But if it is not difficult to cover a distance of 3-4 meters with “wood”, then which beams to use on a span of 5 m or more is already a difficult question.

Wooden floor beams - dimensions and loads

Made a wooden floor in timber house, and the floor shakes, bends, a “trampoline” effect appears; we want to make wooden floor beams 7 meters long; you need to cover a room 6.8 meters long so as not to rest the logs on intermediate supports; what should be the floor beam for a span of 6 meters, a house made of timber; what to do if you want to do it open plan– such questions are often asked by forum users.

Maxinova User FORUMHOUSE

My house is about 10x10 meters. I “threw” wooden logs onto the ceiling, their length is 5 meters, cross-section is 200x50. The distance between the joists is 60 cm. During the operation of the floor, it turned out that when children run around in one room and you stand in another, there is quite a strong vibration along the floor.

And such a case is far from the only one.

I can’t figure out what kind of beams are needed for the interfloor floors. I have a house 12x12 meters, 2 floors. The first floor is made of aerated concrete, the second floor is an attic, wooden, covered with timber 6000x150x200mm, laid every 80 cm. The logs are laid on an I-beam, which rests on a pillar installed in the middle of the first floor. When I walk on the second floor, I feel shaking.

Beams for long spans must withstand heavy loads, therefore, in order to build a strong and reliable wooden floor with a large span, they must be carefully calculated. First of all, you need to understand what load it can withstand. wooden joist one section or another. And then think about, having determined the load for the floor beam, what rough and finishing floor coverings will need to be made; what the ceiling will be hemmed with; whether the floor will be a full-fledged residential space or a non-residential attic above the garage.

1. The load from the own weight of all structural elements of the floor. This includes the weight of beams, insulation, fasteners, flooring, ceiling, etc.
2. Operating load. The operating load can be permanent or temporary.

When calculating the operating load, the mass of people, furniture, household appliances, etc. is taken into account. The load temporarily increases when guests arrive, noisy celebrations, or furniture is rearranged if it is moved away from the walls to the center of the room.

Therefore, when calculating the operating load, it is necessary to think through everything - right down to what kind of furniture you plan to install, and whether there is a possibility in the future of installing a sports exercise machine, which also weighs more than one kilogram.

The following values ​​are taken for the load acting on long wooden floor beams (for attic and interfloor floors):

• Attic floor – 150 kg/sq.m. Where (according to SNiP 2.01.07-85), taking into account the safety factor, 50 kg/sq.m is the load from the floor’s own weight, and 100 kg/sq.m is the standard load.

If you plan to store things, materials and other household items in the attic, then the load is assumed to be 250 kg/sq.m.

• For interfloor slabs and slabs attic floor the total load is taken at the rate of 350-400 kg/sq.m.

Flooring with boards 200 by 50 and other common sizes

These are the types of beams on a span of 4 meters that are allowed by the standards.

Most often during construction wooden floors boards and timber of the so-called running sizes are used: 50x150, 50x200, 100x150, etc. Such beams meet the standards ( after calculation), if you plan to cover the opening no more than four meters.

For floors 6 or more meters long, the dimensions 50x150, 50x200, 100x150 are no longer suitable.

Wooden beam over 6 meters: subtleties

A beam for a span of 6 meters or more should not be made of timber and boards of standard sizes.

You should remember the rule: the strength and rigidity of the floor depend to a greater extent on the height of the beam and to a lesser extent on its width.

A distributed and concentrated load acts on the floor beam. Therefore, wooden beams for large spans are not designed “end-to-end”, but with a margin of strength and permissible deflection. This ensures normal and safe operation ceilings

50x200 - overlap for openings of 4 and 5 meters.

To calculate the load that the ceiling will withstand, you must have the appropriate knowledge. In order not to delve into the strength of strength formulas (and when building a garage this is definitely redundant), an ordinary developer just needs to use online calculators for calculating wooden single-span beams.

Leo060147 User FORUMHOUSE

A self-builder is most often not a professional designer. All he wants to know is what beams need to be mounted in the ceiling so that it meets the basic requirements for strength and reliability. This is what online calculators allow you to calculate.

These calculators are easy to use. To make calculations of the required values, it is enough to enter the dimensions of the logs and the length of the span that they must cover.

Also, to simplify the task, you can use ready-made tables presented by the guru of our forum with the nickname Roracotta.

Roracotta User FORUMHOUSE

I spent several evenings to make tables that would be understandable even to a novice builder:

Table 1. It presents data that meets the minimum load requirements for the floors of the second floor - 147 kg/sq.m.

Note: since the tables are based on American standards, and the sizes of lumber overseas are somewhat different from the sections accepted in our country, you need to use the column highlighted in yellow in the calculations.

Table 2. Here is data on the average load for the floors of the first and second floors - 293 kg/sq.m.

Table 3. Here is the data for the calculated increased load of 365 kg/sq.m.

How to calculate the distance between I-beams

If you carefully read the tables presented above, it becomes clear that with an increase in the span length, first of all, it is necessary to increase the height of the log, and not its width.

Leo060147 User FORUMHOUSE

You can change the rigidity and strength of the lag upward by increasing its height and making “shelves”. That is, a wooden I-beam is made.

Self-production of laminated wood beams

One solution for spanning long spans is to use wooden beams in the floors. Let's consider a span of 6 meters - which beams can withstand a larger load.

By appearance cross section a long beam can be:

• rectangular;
• I-beam;
• box-shaped

There is no consensus among self-builders as to which section is better. If we do not take into account purchased products (factory-made I-beams), then the ease of production in “field conditions”, without the use of expensive equipment and accessories, comes first.

Just Grandfather User FORUMHOUSE

If you look at a cross section of any metal I-beam, you can see that from 85% to 90% of the metal mass is concentrated in the “shelves”. The connecting wall contains no more than 10-15% of the metal. This is done based on calculation.

Which board to use for beams

According to the strength of strength: the larger the cross-section of the “shelves” and the farther they are spaced apart in height, the greater the loads the I-beam will withstand. For a self-builder, the optimal I-beam manufacturing technology is a simple box-shaped structure, where the upper and lower “shelves” are made of boards laid flat. (50x150mm, and the side walls are made of plywood with a thickness of 8-12 mm and a height of 350 to 400 mm (determined by calculation), etc.).

Plywood is nailed to the shelves or screwed with self-tapping screws (not black ones, they do not work for cutting) and must be placed on glue.

If you install such an I-beam on a six-meter span with a step of 60 cm, then it will withstand a large load. Additionally, an I-beam for a 6-meter ceiling can be lined with insulation.

Also, using a similar principle, you can connect two long boards, collecting them in a “package”, and then put them on top of each other on an edge (take boards 150x50 or 200x50), as a result, the cross-section of the beam will be 300x100 or 400x100 mm. The boards are placed on glue and tied together with pins or placed on wood grouse/dowels. You can also screw or nail plywood to the side surfaces of such a beam, having previously lubricated it with glue.

Also interesting is the experience of a forum member under the nickname Taras174, who decided to independently make a glued I-beam to span a span of 8 meters.

To do this, the forum member purchased 12 mm thick OSB sheets and cut them lengthwise into five equal parts. Then I bought a board 150x50 mm, 8 meters long. Using a dovetail cutter, I used a dovetail cutter to select a groove 12 mm deep and 14 mm wide in the middle of the board, so as to create a trapezoid with a downward expansion. OSB in grooves Taras174 glued it in using polyester resin (epoxy), having previously “shot” a strip of fiberglass 5 mm wide to the end of the slab with a stapler. This, according to the forum member, would strengthen the structure. To speed up drying, the glued area was heated with a heater.

Taras174 User FORUMHOUSE

On the first beam I practiced “pushing my hand.” The second one was done in 1 working day. At cost, taking into account all materials, I include whole board 8 meters, the cost of the beam is 2000 rubles. for 1 piece

Despite the positive experience, such “squatter construction” did not escape several critical remarks expressed by our experts. Namely.

The Balok-house for tramps

There is such a belief: for every person on the globe there is a place,
which is unknown to this person, but can be seen in a dream. If a man
one way or another will still find him and settle,
he will be happy until the end of his days.
Oleg Kuvaev “House for a Tramp”
Better a bad beam than a good tent
From personal experience

They are different: unsightly, blown from all sides and with an old stove; good-quality, well-insulated, with a canopy and a cast-iron stove; pretentious, with glazed verandas, large stoves, baths and toilets; Spartan... They are different. But they all have one thing in common: they are always desirable and attractive to travelers, hunters, tourists and other wandering people.

They are scattered across the vast expanses of the North, from Murmansk to Chukotka. A traveler who accidentally wanders into a ravine remains unaware of the name of the owner, this simple monument of civilization. However, each beam has its own owner. The beams don't live very long without their owner. He begins to wither, grow moldy and somehow quickly die. And this is not just a metaphor, I have seen dead beams - a sad sight.

Beams are most often placed in fishing areas - hunting or fishing. Less often they are placed as a base pass, on winter roads or in places where reindeer herders roam.

Rarely does one person put up a beam. More often this is a group of like-minded hunters/fishermen, or as they used to be called a gang of industrialists.

The place for the beam is chosen in the summer. There are several criteria for its selection - it should be located close to fresh water, the place should not be flooded and preferably be picturesque. With the onset of winter and the formation of a winter road, the beams on a sleigh are dragged by an all-terrain vehicle or tractor to a favorite place.

Beams can be framed - sheathed wooden planks; log cabins (less often), metal (container, 5-ton tank, cabins from barges or boats). I once saw beams made from doors.
A proper Chukchi gully must have a canopy, or as they are most often called a dressing room. The main thing in the beam itself is the stove.

The dimensions of the furnace depend on the size of the beam.

But she will definitely stand near the door. In good-quality beams, the stoves are often lined with stones on the sides so that it retains heat longer. The stoves themselves are all-metal and have “burner holes” on which you can cook food faster. In order not to “drown the street,” a valve is installed in the chimneys, with the help of which the draft is regulated, which in turn helps to use fuel economically.

Fuel, as well as beams, is brought by all-terrain vehicles/tractors/cars or collected from driftwood (if the beam is located near the sea) or bushes. They heat with either coal or wood. Everything in the tundra is subject to strict logic, on which traditions grow. Everyone who stays in the beam will definitely leave an armful of firewood or branches so that the next guest can easily make a fire. There are nails nailed to the walls around the stove and a wire stretched for drying clothes or shoes.

The next beam element is the bunk.

Most beams have two tiers. They can be wooden, or they can be ordinary Soviet “two-story” beds (however, I have only seen such bunks a few times).

The most comfortable bedding is deerskin. But you don’t often see such luxury lately; most often you see an ordinary cotton mattress, which, before lying on it, is “simmered” near the stove for a couple of hours.
The table, as a rule, is placed in the middle between the bunks, which in this case act as benches. One of the end sides of the table rests against a wall with a window.
There are rarely more than two windows in a beam, and most often there is one. And it won’t even be a window (in the understanding of a city dweller), but rather a large window. This layout is dictated by the reduction in heat transfer from the beam.
In addition to the above basic items of any beam, you may come across “optional” but very useful interior elements, such as shelves, cabinets, lockers, washstands, etc.
Since childhood, I remembered the rule - when leaving the village, leave some of the food. IN Soviet time in any beam one could live peacefully from 2-3 days to a week. In the 90s, with the lack of food in the villages themselves, little was left in the ravines. But salt, matches and crackers can be found in almost all beams. In addition to food, they leave behind clothes and old shoes - cut-off felt boots, kirzachi, sneakers. While your shoes are drying near the stove, you fit into “oversize slippers” and feel almost at home.
In a rare ravine you will not see a file of old newspapers. Moreover, the further into the tundra, the more erotic the press becomes. The hit of all beams is “Speed-info”. In addition to literature, you can also find more mundane entertainment in the beam: cards, dominoes, etc.
The main enemies (besides humans, of course) of any beam are the bear and the wolverine. One can only be amazed at how inventive these animals can be. The bear most often rushes through a door or window.

Wolverine is more cunning; she can gnaw a hole in the floor or wall, and sometimes even in the ceiling.

Traces of the wolverine's presence are visible, as they say, to the naked eye. Everything is turned upside down, literally. Having climbed into a beam, a wolverine can live in it for several days. Hiding under the bunks. Therefore, when entering a ravine, experienced tundra dwellers look there first. They told a story when, after a riotous evening gathering, one of the men woke up to go out to relieve himself and saw how a wolverine calmly crawled out from under the neighboring bunks and slipped through the ajar door. Many methods have been invented to combat animal pests. In areas inhabited by polar bears, hedgehog shields are made on doors and windows, with nails facing outwards. But the surest remedy is not to leave food waste near the beams and especially not to gut game and fish. They are what attract predators.
The most pleasant moment of staying in the beam is the evening exercise. Things are hung on nails and wires near the stove, which hums cheerfully, along with a “reaching” kettle. Everyone, well-fed and satisfied, sits or reclines on their bunks and conducts leisurely midnight conversations “about life.”

Sometimes it seems to me that it is precisely for such conversations that people go to the tundra. How many conversations did each beam listen to! From the apartheid policy in South Africa to neighborhood gossip. From quantum mechanics to the addroid collider, and every third person will know exactly why it has not yet launched. I’m not talking about “your jigs are rubbish, look at mine,” or “I’m sitting in a hiding place...”. And all these “oh yeah?!” or “seriously?” flavored with dozens of mugs of tea and liters of vodka. Because “what’s the point of going without this?” And of course, the most delicious gastronomy that a person who has ever visited the tundra has eaten is prepared in ravines.

Although, what about gastronomy? Everything is delicious in the tundra.
A beam with a bathhouse is considered especially chic. This is generally from the category of transcendental pleasures. Such places are revered as tundra shrines. For a Russian person, a bathhouse is like a holiday in the city, and even in the tundra... Jumping into a lake, river or snow, and then going into a heated, somewhat smoky ravine and waving “goodbye” is many times cooler than a week in Turkey.
Humanity invented the iPhone and iPad, launched the Hubble telescope into space and learned to clone animals, but what does it matter when, having crossed the next pass, you find in the distance a small beam with a match pipe. With your last strength you will make the final push towards this primitive, but ideally perfect creation of man, in which you will find shelter, warmth and food.

And already falling asleep, your gaze will rest on the inscription on the ceiling made by the tramps of your predecessors: “People don’t shit in the beam! It will be useful for someone else.”

For the installation of interfloor ceilings and rafter systems you will need a modern structural material - a wooden I-beam. Lumber is widely used in the construction of low-rise residential buildings (frame, block, brick and wood), commercial buildings and industrial premises.
