Profiled bar: pros and cons. Construction of houses from profiled beams

It has long been proven that living in a wooden house brings its inhabitants a special state of mind and excellent health. You can admire the wonderful appearance of a wooden hut endlessly. However, in order to settle in such a tower, not only certain funds are needed, but also important knowledge about the differences between one type of timber and another. Glued or profiled bar, price, quantity of material, finishing methods and type of foundation - everything matters. On the profiled beam the price can vary from 1000 to 2000 rubles per log 6 m long.

Why are wooden houses popular?

It is difficult to argue with the fact that natural wood has many advantages over stone, brick and especially concrete materials. Fibers of the fibrous-cellular structure of the wood are located along the entire length of the trunk. This makes the material non-heat-conducting, lightweight, breathable, durable and elastic.

Thermal insulation properties of wood are several times superior to concrete and brick. In summer the house breathes coolly in this house, in winter the comfortable temperature is kept perfectly. The natural qualities of the material do not allow air to stagnate in the house, there is a natural ventilation, so mold and dampness are not the satellites of the life of the tenants. On the contrary, house blocks from profiled beams are built exclusively from coniferous species of wood. This contributes to the creation of a certain microclimate with a special quality of air in the dwelling. Vapors of coniferous resins have a positive effect on improving people's health, strengthening immunity.

Of what modern buildings are built

For the erection of dwellings from wood, not only round traditional logs and old technologies are used. The construction of houses from profiled beams proved to be a good idea. What is it possible to build a wooden house today:

• Of raw unprocessed timber of minimum value;
• From calibrated, which has more precise geometric dimensions and a qualitative appearance;
• From a profiled beam, which differs from the previous one by connecting threaded elements, simplifying the assembly of the log hut;
• From glued beams, which are obtained in the process of joining lamella boards under the influence of high pressure and temperature, which makes these blanks quite expensive, but strong and light.

The technologies for building houses for each of these materials are similar in the main stages. Differences only in the time of natural shrinkage of structures, in methods of insulation and finishes.

The glued beam does not need external grinding of the walls, it is not necessary to wait for the building to shrink. Even inside, it looks great without additional finishing.

Consequences of using undried wood

Construction of profiled beams has its own characteristics. First of all, the material has a certain degree of humidity, we can say, "dryness". Ideally, this indicator should be approximated to a level of 14-15%. Basically for construction use wood of natural humidity, that is absolutely not dried after sawing. This option is much cheaper than the additionally processed bar in the thermal chamber. Profiled dry material when assembling the house will give a minimum shrinkage, which greatly accelerates the construction time.

Undried logs are more susceptible to bioprotection by fungi and mold, even antiseptic impregnations help little. The walls of a house erected from such a tree, giving away moisture, can be severely deformed, which will lead to cracking of the windows, door screw-ups and damage to the roof. Is it worth saving initially to get such problems in a couple of years?

Profiled bar: pros and cons

Is there an alternative? Among all types of wooden materials used for the rapid erection of modern and beautiful buildings, the most widely spread profiled glued beam. How does it differ from other species?

From the title it becomes clear that this is not an array, but an invoice consisting of several layers. The density of the well-dried material is such that a house built of it can be installed immediately after the completion of the final work. While projects from a conventional profiled beam are built in several stages:

• First, the main house box is assembled on the foundation;
• Then the works stop for almost a year;
• After the final shrinkage of the frame, installation of floors, roofs, communications, internal and external finishing is carried out.

This duration of construction can not be considered a plus. However, the production of the profiled beam is at a good pace, which indicates the demand for the material on the market.

Substantial advantages

A significant positive moment of using this material in construction can be called a simple high-quality assembly with minimal costs for insulation of premises. For finishing the outer surface of the walls, it is enough to grind the wood well enough to make the structure shine in the sun, like a fairy tale.

A great positive quality can be considered and the fact that the construction of houses from profiled beams practically does not require special finishing of the internal surfaces of the walls of the house. The tree itself serves as a beautiful decoration and heat insulator.

Profiled bar (pros and cons always will be) is a universal building material if you want to have a bath or an additional guest house on the site. The technology of assembling a small building differs little from the assembly of a large tower.

Nothing is eternal under the Moon

Rains, snow and frost affect both the concrete and the profiled bar. Pros and cons of the consequences of these natural phenomena become clear only in the process of exploitation of the dwelling. The house will be warm without additional measures if it is in the southern regions of the country. Where frosts reach too low temperatures, the profile bar (dry) must be necessarily insulated from the outside of the house. This can be done by additional wall cladding with mineral wool and lining or siding.

The tree is an organic material and is susceptible to burning and rotting. Antipyrene impregnations can only be temporarily protected against fire from an open flame. For safety from fungi and mold, the profiled bar (photo) must be regularly treated with antiseptics, which sometimes complicates residence.

How to build a house: from spruce or from cedar?

Pine and spruce trunks are the most affordable and cheap raw materials for the production of timber. Wood of cedar is more expensive about one and a half times and is considered elite not so much because of the price, but because of its density and medicinal properties. In addition, it is very durable and resistant to dampness.

Saw-timbers from a larch differ the amazing stability to a moisture. Such logs do not rot even after several years of being under water. That is why, in accordance with the technology, the lower row of crowns of the house is laid from this wood. The larch bar is the most expensive, but if you save at this stage, in a few years you will have to dismantle and rebuild all the walls of the house.

Pine logs are least susceptible to cracking both at the drying stage and during the process of months of natural shrinkage. The upper part of the tower can be built from this material. One of the important conditions for the assembly of walls is approximately the same moisture index of the timber from different wood. Otherwise, the entire structure may become skewed. It is the danger of such an event that is the main disadvantage when building wooden houses. Experts say that the result of all the work depends on the ability to handle the humidity of logs.

In the old days, the folded "black" box of the log had to stand in this form for at least a year, subject to all winds, rains, sun and hurricanes. Only then the workpiece was dismantled into logs and again collected already in a permanent place. Then there were works on caulking, laying the floor and erecting the roof.

The modern production of profiled beams is arranged in such a way that when the logs are properly dried in a warm chamber they are put on sale in the state of the required humidity. If such material is purchased, then all construction can be completed in one season.

House-constructor: what you need to know

Profiled bar (the price depends on several factors) is made using the following technology:

• The log from a single trunk of a tree (whip) is cleared of branches and bark;
• The array is processed from four sides to giving it the correct geometric shape with a certain number of spikes on both sides.

The transverse dimensions of the workpiece must be the same along the entire length and more than the calculated ones, since they decrease during the shrinkage by several millimeters. For example, in order to produce a profiled bar 200x200, the workpiece cross-section must be equal to 210 × 210 mm.

The standard length of the beam is 6 meters, the shape in the section is trapezoidal. On the upper and lower sides there are grooves of the "mama-papa" type at full length. When stacking logs one on another, such thorns and grooves prevent them from moving, which is a guarantee of building strong walls.

For the possibility of a simple enough assembly, home sets from a profiled beam are sometimes called "designers".

In the corners, at the door and window openings the binding of the timber is made between each other. To do this, drill through round holes in the joints. After that, insert and finish with blows of heavy hammers special birch nagels (stakes) of square section. In the process of natural shrinkage of timber, the timber "tightly" grasps with nagel, which ensures the reliability of the walls for many years.

Wooden tower: where to start?

It is clear that you can not build a house in the air. The first thing to take care of is a piece of land. The next step is to select the project and design the design estimates, which includes the engineering component with full calculations and architectural and construction with details and details of the future home.

Projects from profiled beams have a preliminary estimated estimate, in which the required amount of materials is indicated. When calculating the calculations, the dimensions of the construction and the cross-section of timber are taken into account.

At the next stage, the foundation is installed under the construction. It is recommended to make either a pile or a pile-tape variant of a shallow (55-70 cm) fill. Separate details of the choice depend on the location and relief of the land plot intended for construction.

On the firm foundation lay waterproofing, a layer of insulation, then the first row of logs that are attached not only to the corners between themselves, but also to the concrete base. Further construction is carried out according to the project of the selected material. If a profiled glued beam is purchased, the house is assembled immediately "for finishing": a thin layer of linen insulator is laid between logs, windows and doorways are made, and the roof is closed and closed.

A common mistake in the assembly of wooden structures is the rigid attachment of trusses and medium ridge runs to shrinkage. How can this happen in the future? In the process of natural drying of wood walls, the angles of connections between the elements of the roof structure change . As a consequence, bolts that hold the roof slopes can be torn. As they say, "hurry up - then you'll cry."

Is it possible to reduce the cost of construction?

Among the most budgetary options for building a house of wood, you can call the following kit:

• Foundation of screw piles;
• Thin in 100 mm profiled bar (pros and cons are clear without unnecessary words) of natural moisture;
• Minimum insulation of floors and roofs (mineral wool up to 100 mm thick);
• Simple wooden frames;
• Refusal to "crawl" when installing windows;
• Use for the fastening of wreaths of ordinary metal nails and nagels;
• Minimum of finishing materials;
• Roof covered with slate or onduline.

Using the most affordable means, you can, of course, build a house. The fact that this dwelling will stand and serve its owner will remain a question to which only time will answer. For a long time the truth is known that "the miser pays twice." So is it worth it to save on your own comfort, if saving money and reducing costs can be achieved in other ways?

There are other savings options, in which you can save the budget, using solid materials for construction. First of all, you need to reduce the number of halls and corridors in the project. When buying a flat plot of land, there may be a noticeable decrease in basic expenses. In complex terrain, it is worth taking into account its features and using elevations in the compilation of the project.

The cost of construction can be significantly reduced by buying a ready-made structure from glued or profiled beams. The peculiarity of this option is that the house is delivered to the buyer in disassembled form, with numbered elements and detailed assembly instructions. Any person who had studied at school could understand it. In addition, the majority of companies with the strength of their employees put the design completely and give the owner what they say, "turnkey".
