Construction of the wall framing

The process of assembling the wall frame begins with the processing of the basement at home - covering waterproofing layer. Depending on the size of frame houses on either side of openings wider than 1,5 m provide additional vertical posts that provide structural rigidity, protecting the gap and facilitate the fixing of tiles. For vertical mounting rails framework used compound of 3 - 4 nails 125 mm in length. Skeleton racks are placed at intervals depending on the width ordered or provided in the project of finishing and insulation panels - usually within 60 cm in the calculation of the gaps between the posts should also take into account the size of window and door openings. As an upper horizontal belt carcass using dual-beam, the total thickness of which corresponds to the size uprights and the height is calculated on the perception of stress is higher than the structures on the site where the frame between the uprights have the greatest distance, or on site at opening of maximum width. In the area of ??this opening the upper horizontal beam of the frame can be strengthened an additional wooden beam. Upper chord frame walls can also serve as a bar, located at the upper edge of the lower tier of the roof trusses. Installation of frame start with fixing the lower belts. Accuracy of angles between the belts should be checked before assembly. Angular vertical bars set with a plumb. Vertical angle bars and ordinary rack frames the side walls are placed in accordance with the dimensions shown in the draft, if necessary, carry out the frame. Between the corners after the markup set at intervals of 4-5 mm of the uprights of the framework. Supporting a horizontal board nailed to a height of 1.5 m along the entire length of the wall, after which it is possible to fix the rest of the vertical bars of the walls. Then nail the upper belt sidewalls. If he was going out several runs in the interval between the end part of the belt fasteners to the vertical bar should be located not less than three studs. Vertical frame end walls harvested from long boards so that the longest reception was at the level of the ridge. After mounting the upper frame side walls belts corner posts are fixed with nails or bolts. Stability of the skeleton with respect to wind loads increase with struts, fastened to the inside of the frame, or using hard plates lining. After their attachment can be removed temporary supports. The upper level window and door openings are at a height of 2.1 m from the design mark of sex. Top frame openings set independently of the upper horizontal support beams (upper zone) of the framework. If the top frame of the opening should be combined with a supporting structure, it is done in accordance with the drawings. Bottom of the window measured from the top timber framing and strengthen additional racks. When calculating the location of the vertical frame rails under the window opening should take into account the radiators. Frame rail must be located in front of the battery bracket. The size of openings in the horizontal and vertical should be increased by 30 mm compared with the respective sizes of window frames. Placing the heating pipes relative to studs checked before final installation of the latter. The distance from the bar to the surface of the pipe must be at least 24 cm Racks mount, raising the upper zone, and plumbing, and if they had to be stored on site, then manually or using a crane. If the timber stands must be processed in a horizontal state, should make sure that it does not sag in length. Implications of possible bending legs can become weakened joints. For the installation of large-span roof trusses in the middle passage install additional horizontal support, placing it below the upper zone of the reference frame side walls. This backup and how to use the forest, and as additional support for the movement of the farms in the process of mounting them on the length of the frame. It also prevents excessive deflection of the farm. Farms are fixed or nails, or with the help of overhead items. Skew nailing should be done at a distance from the edge to avoid damaging the wood. Installing trusses begin from the end of the building. Farms are fixed, from the end wall. Since fixing the time, the nails do not pierce through, so that reliance can be easily removed after the final installation. Farms should be strictly vertical, so that they work properly statically. The final attachment is carried out by perceiving wind loads braces that set through a gap between the farms. On roofs with large surface area of ??the roof used a forward pad on the boards nailed to the upper edge of the roof on a diagonal or angled for rigidity. As a design eaves on its ends (at the gable houses) use cantilever beams of the same height as the rafters farm or rafters. These beams are fixed with nails in 60 - 70 cm along the length of the gable. Other end of the beam attached to a farm located near butt. The free ends of beams pass over the end face of the house far enough and are fastened with nails to the top bar of the pediment. Inserts, fixed on the top rod of the pediment cornice between the cantilever beams, do not admit their shifts when the roof rafters exposed to stress. The lowest cantilever beams on the corners, where the combined edge and the longitudinal rods, set at an angle of 45 °. These beams also support the end of the lateral eaves.
