In detail: do-it-yourself repair in a trailer from a real master for the site my.housecope.com.
The construction of a private house usually starts with a "construction trailer". On the market you can find many offers for the purchase of new or used wooden cabins. Even such a concept as "block container" has appeared in everyday life. It is made of metal, has a large number of equipment options and can already be used as an element of modular housing construction.
But it is a do-it-yourself change house on a wooden frame that is the most economical and optimal solution for a prudent owner. After completion of construction, it can be used as a guest house, a shed for inventory and equipment, converted into a bathhouse or transported to a summer cottage.
The further use of the change house depends on its size, device and finishing materials.
As a small barn, no internal partitions are needed. There is also no need to insulate walls, floors and roofs.
If you plan to use the change house as a seasonal residence (for example, a summer garden house), then you can provide for the presence of an internal layout. It is better to carry out insulation at the construction stage - when using heaters, the change house with your own hands will be better to keep warm in spring and autumn, and in summer it will not get very hot in the sun.
For a construction trailer, lining can be limited to inexpensive and simple materials. Conversion into a garden or country house will only require revision in terms of decorative finishes.
It is best if the interior space is divided into at least two rooms. For example, the house in the first photo can be represented as follows.
Video (click to play).
A small vestibule-hallway and a large room with one small window - a typical DIY construction trailer.
And this is an improved version with three windows, which can be conventionally called a house with a living room and a bedroom.
In this diagram, the change house consists of three rooms - a vestibule and two equivalent rooms.
And of course, before starting construction, you need a simple drawing indicating the main dimensions.
Without it, it is impossible even to calculate the amount of materials.
How to build a change house - step-by-step instructions for building a change house begin with the foundation.
The peculiarity of a small wooden structure is its low weight. But even this does not mean that it can be placed directly on the ground. To protect against the effects of soil moisture (including precipitation in the form of rain and snow), an elevated base is required.
The simplest view is columnar foundation... Its strength is enough to withstand the weight of the change house. For temporary placement (and setting a horizontal level), bricks or cinder blocks are often used, laid simply on the ground. But in any case, it is better to use full-bodied blocks. Such an option as in this photo, even for a temporary foundation, is not the best choice, especially since the block was initially laid sideways and the pressure falls not on the walls, but on the voids.
Cinder block, although it belongs to concrete, but hollow blocks are used for the construction of walls.
Even a columnar foundation must be done according to the rules. A small depression is dug under each base, the bottom is rammed, a pillow of sand (at least 20 cm) is poured, which is poured with water and compacted, and blocks are laid on top. The sand prevents the capillary rise of moisture and acts as a drainage.
There are alternative options for a columnar foundation.
A geomembrane is laid on the ground cleared of the top layer, a layer of sand is poured on top, and then the base is laid out from the blocks.
Instead of sand, you can use fine or medium crushed stone.
Even large-format paving slabs can serve as the basis for a columnar foundation made of blocks.
For permanent deployment, it is possible to use asbestos-cement pipes dug to the depth of soil freezing and filled with concrete as pillars. This is if you are building not a construction, but a summer cottage with your own hands.
The distance between the posts is usually chosen based on the dimensions of 1.5-2.5 meters. Therefore, in addition to the corner supports, there will be 1-2 additional ones along the perimeter plus internal ones (for partitions and for a beam that provides the rigidity of the subfloor).
In addition to the columnar, the arrangement of the slab foundation is applicable. Of course, a reinforced concrete monolith is redundant for such a structure, but large-format paving slabs on a sand-filled foundation are quite suitable.
How to build a change house with your own hands, for this you only need dry wood. But this is not enough - all wooden elements of the frame and cladding must be treated with antiseptics. Moreover, working out is suitable only for "underground" elements, but the change house does not have them, and drying oil is only temporary protection from moisture and mold, therefore it is necessary to use antiseptics and fire retardants.
A bar of 150 × 100 mm is best suited as a lower strapping. This size is even used for the grillage of a columnar or pile foundation of wooden and frame small residential buildings. The simplest corner joint is in the wood floor.
This is followed by a second crown made of 100 × 100 mm timber. Moreover, the installation takes place with an internal "step" between the crowns. This is the optimal device for insulated floors. On a shelf of 50 mm, logs are mounted for a finished floor with a section of 100 × 50 mm.
Corner and bearing posts (for partitions and doors) are made of 100 × 100 mm timber, intermediate posts (including for window fastening) are made of 100 × 50 mm timber. They are attached to the harness using metal corners,
having previously set the level and fixed with temporary jibs.
Alternatively, you can use pins, which will additionally fix the corner connection of the strapping.
A frame wooden change house can be erected not element by element, but in sections mounted on the ground. This also applies to the walls,
and to the top harness assembled with the rafter system.
But such a technology will require the involvement of assistants, therefore, when building a change house with their own hands, more "lighter" (by weight) techniques are often used.
The upper harness follows the same rules as the lower one. The supporting beam along the perimeter has the same cross-section as the corner posts of the frame. The connection of the elements is carried out in the floor of the tree, having previously selected the grooves at the intersections. First, the long side is mounted, fixing it to the racks with a temporary fastener.
Then the cross bar is installed. After checking the levels and corners, the upper harness is finally attached to the posts with a metal corner.
For a pitched roof, and this is the simplest option, the upper strapping can be performed in two levels, when the front (or rear) racks are made at the required slope angle.
But there is also a more complex option using wall racks.
Intermediate posts (100 × 50 mm) are also fixed to the lower and upper strapping using corners.
The distance between the uprights is selected based on the width of the insulation and the size of the sheathing sheet material. If lining is used for interior decoration, and for exterior - block house or siding, then only the width of the insulation is of decisive importance. The usual recommendation is 600mm between the tine axles. This dimension is tied to drywall.
But when sheathing OSB (OSB) (the most common material for frame technology), each sheet will require cutting by 50 mm. Therefore, if the inner lining will be made of clapboard, then it is better to choose an axial distance between the posts of 625 mm. The size of the gap between the posts will be 575 mm, which is permissible for laying mineral wool with a width of 600 mm and a deformation strip of 50 mm.
For racks, between which windows and doors are mounted, their own criteria. You can, of course, make the frame of a paneled door and window frames from a bar yourself, but more often they buy finished products. Therefore, they will require the installation of additional struts and struts.
And if the doors are standard in width and height, then the windows can be large
or vice versa, a little more than a window.
Do-it-yourself change house There are many ways of attaching the rafters to the Mauerlat (in this case, to the upper strapping bar). The simplest one uses metal staples. For a more reliable fixation, you can either cut a groove in the rafter, or use a support bar.
Rolled waterproofing is attached to the rafters, and the crate is on top. The pitch of the lathing depends on the type of roofing material and the angle of the slope.
The most inexpensive is ondulin (a modern analogue of slate). For an angle of less than 10 °, a continuous crate is made, up to 15 ° - a step of 450 mm, more than 15 ° - 600 mm.
Change house do it yourself floor device. First, boards (or OSB-3) of the subfloor are attached between the logs. The protruding edge of the lower strapping beam (150 × 100 mm) is used as a support.
Then the surface of the subfloor is covered with a waterproofing film. For this, dense polyethylene is often used, but roll materials with bitumen or polymer-bitumen impregnation are considered more reliable. Hydroizol... The film is laid with an overlap between the strips of at least 20 cm, with gluing of the seams with construction tape. The edges of the stripes should go over the walls (the same 20 cm).
Insulation is placed between the lag. Better to choose mineral wool, for example URSA(URSA). Unlike Styrofoam, it is non-flammable and rodents will not start in it. Its only drawback is hygroscopicity and the property of loss of insulating properties when saturated with moisture (the same condensate). Therefore, a gap is needed between the finished flooring and the vapor-permeable membrane, or use Izospanthat does not allow water to pass through - this will protect the mineral wool from direct contact with water and allow water vapor to escape from it.
A tongue-and-groove board is best as a finishing floor. The principle of connection of the coating "thorn-groove" allows you to further protect the insulation from water ingress into it.
But you can lay the same OSB (OSB), and linoleum on top.
In order for the change house to be warm, it is necessary to insulate the ceiling. Of course, cold air will not go down from top to bottom, but warm air will "evaporate". In addition, when it gets on a cold floor, it will cause condensation. That is why even for a pitched roof it is necessary to equip a small "attic" distance and insulate it with mineral wool. The principle is the same as for the floor: overlap (board or OSB), waterproof Izospan film, insulation (mineral wool).
Decorative cladding from the inside is performed in the same way as walls.
The classic frame structure sandwich has several layers: inner lining, vapor barrier film Izospan, insulation between the frame posts (mineral wool), a vapor-permeable membrane, a spacer bar (for the ventilation gap), OSB and decorative cladding.
In practice, the outer cladding for a change house can be "simplified" to one outer layer - either OSB or decorative trim. Considering the low "aesthetic" properties of OSB, the second option is often chosen, although the boards can be painted in any color like an ordinary wooden surface.
Most often, a house block is chosen for outdoor decoration.
It is stronger and "warmer" than lining and is more suitable for outdoor decoration. You can use imitation timber.
Vinyl siding is preferred by some as an alternative to wood paneling. It does not require maintenance and paintwork.
Interior decoration can also have an economy version of OSB (OSB) or Fiberboard,
which can be painted or covered with vinyl wallpaper.
But lining with wooden clapboard is more common.
An internal partition must be foreseen while developing the project of the change house, but it is not too late to equip it later.The main thing is that it is attached to one of the floor logs from below and the ceiling beam from above.
Outside and inside, window frames and doors are attached. The corner joints are trimmed from the outside with planks or wooden profiles, and from the inside with plinths and fillets.
