Building a house for 3 weeks: carcass

A good frame on the main characteristics does not yield to the traditional for our country construction technology

Before you begin to work on the construction of partition walls is necessary to perform the warming platform and sew up her sheeting.

Take part in our competition and win domokomplekta! Take part in a competition.

She warming platform

The project envisages the arrangement of the floor inside a log raft foundation. To lag, we also use the board 145 * 45 mm in size napilennuyu. To the bottom of the pile cap, as well as to each lag on both sides fasten the bars 45 * 45 mm over the entire length to maintain polystyrene performing the function of insulation at the overlap. Said bar takes on the height of the board of 45 mm, thereby effectively floor insulation would be 100 mm.

If necessary to increase the thickness of insulation in the floor platform can instead limiting bars nail along the lower edges of each board with the joists defining section 20 * 100 mm. Thus, the platform can be insulated with the entire log height.

Next, perform the marks on the raft foundation in increments of 56 cm along the axes. This step is dictated by the size of standard polystyrene sheets - 100 cm. insulation sheet is cut in half, we obtain two pieces of a width of 50 cm. Sawed-off piece is placed in the ceiling and is based on full of logs on bars. According to one centimeter on each side of the foam remains on the seam. After thorough foaming windproof such overlap is obtained and in combination with flooring sheets from above SIR does not require a vapor barrier.

The final stage of platform installation - OSB sheathing her sheets. For this purpose, we used a 18 mm thick OSB with tongue and groove edge. Plating is performed in Extension sheets, the joints must diverge approximately half the length of the sheet. Availability tongue and groove edge allows join sheets anywhere, not agreeing with lags.

When using a conventional edge, all the joints of sheets of OSB must fall on the wooden bearing elements. In longitudinal direction - a floor joists, laterally, perpendicular joists are mounted so-called bridging.

It is understood that after sewing the platforms SIR sheets necessary to ensure its protection from rain and cover film before the roofing.

The modest size of our house make it possible to move immediately to the next stage - the construction of partition walls.

frame

The design of our frame house is a hybrid of the Scandinavian and North American systems. Of American technology, we took a second upper banding board on the walls. This is due to the fact that the side walls have longer than six meters and are assembled from shorter segments. In addition, the upper strapping board connects the walls together, it allows you to distribute the load from the rafters to the walls evenly.

According to construction standards for the construction of timber frame houses must be dry, moisture content below 18%. Therefore, we use dry planed boards, humidity 10-12%. The cross section of the boards to studs 45 * 95 mm, made of the same rafter board section 45 * 145 mm.

In the presence of the project it is advisable to saw all domokomplekta advance in size, which significantly reduces the total time of construction. Construction of frame houses by the "platform" implies a horizontal assembly of walls on the already assembled base, followed by lifting and fixing.

Installation is as follows: prepared by the top and bottom boards are stacked on the platform and are spread over a distance corresponding to the height of the wall. After that, there is rack layout. The height of the racks have 2500 mm, pitch axis 625 mm. Such a step, firstly, provides the distance between the uprights corresponding to the width of the heater, secondly, to the width of the sheet SIR - 1250 mm (625 * 2), which we plan sheathing frame house inside. The height of the racks have also not accidental, and corresponds to the height of the sheet OSB, so all of our Cabin framework will be made OSB sheets with little or no waste, which fully meets our concept construction.

Walls collected on nails with an annular knurling 90 mm long.
Once the wall is assembled fragment on the platform must be as accurate as extinct it diagonally with a tape measure and a temporary liberated jib.

The next stage of the walls are raised and also fixed with nails to the bottom and fastened together.

After this shot jib and frame for rigidity is sheathed with OSB sheets. OSB plates are mounted with a gap of 3-4 mm deformation.

At the junction of internal walls to the outer walls we originally on the partition end of the strip was attached vapor barrier to create a continuous sealed circuit. Skip to main canvas vapor barrier, these bands are subsequently attached to bilateral adhesive tape.

In terms of all the work by filing for studs, knocking up, lifting and installation of wall takes only 1-2 days.

truss system

After the carcass immediately proceed to the installation of roof system, as quickly as possible to make a roof. The roof will protect the house from precipitation platform and allow in more comfortable conditions to carry out further work on the construction and decoration of the house.

As noted earlier, we have a simple roof gable, it is the most simple, reliable and low-cost option Roof perfect for a country house. The advantage of manufacturing simplicity, simplicity of installation and minimize the risk of a mistake, which is very important for samostroyschika.

In this house we apply naslonnuyu truss system - and this is when the top and bottom of the rafter is supported. That is, the top rests on the ridge pole, and on the bottom banding board.

Design angle of slope of the roof of 21 degrees, thus taking into account the small size of the house, you can see that we are not planned attic, as its height would be too small for effective use - it also simplifies and reduces the cost of design.

Work on the project, rather than on the knee, allowing all the manipulation of cutting rafters in size exercise below, strictly according to the drawings, and after cutting to submit rafters up and fix them in place.

Rafters we also manufacture of dry planed boards section 45 * 145 mm.

Step rafters have the same as that of the studs - 625 mm. Between the rafters, on the edge of the wall mount spacers, which serve to maintain the insulation and prevent torsion rafters.

The final phase of the installation of roof system - a device offsets gable eaves of the roof, which we are doing on the outriggers or in common parlance to "mare". Fillies are attached to the first rafter mounted on the house. Spacers inserted therebetween restricting insulation and stiffening assembly.

The following article will tell you about the device and a vapor barrier insulation.
