As we all know, truss rafters are an efficient, safe and economical roof support method. These woods are usually supplied by professional wood manufacturing companies. Only when properly installed and used can they play their role to the maximum. Truss rafters are made of structural grade wood of the same thickness and connected by stamped metal connectors. They can be used to support the roof of a building, the ceiling of a room, and the floor ( in some cases ). Generally, the interval between them does not exceed 600 mm . They replace the ordinary rafters used on traditional cut roofs, can be quickly built on site, and are suitable for various types of buildings such as residential, commercial and industrial buildings. When properly installed in a building, truss rafters can provide a structure that meets the requirements of established building codes.
The spacing between trusses is usually 600 mm, but it is sometimes set to 450 mm or 400 mm to carry heavier weight. For truss rafters, they must be carefully installed, fixed and tied so as to provide a strong and stable roof and a good roof cover for the platform. At present, most of the fixed wooden connection fittings can be purchased from the official Sincerityhardware.com website.
Wallboards should be vertically fixed and kept on the same horizontal line. The length of the wallboard should generally not be less than 3 meters, or the length should exceed the distance of at least 3 joists / rafters or trusses. Wallboards shall be connected in half lap joints at corners and along the length direction. The support belt shall be fixed on the wall panel with a maximum center distance of 2m. If the steel strip does not become an interlayer joint, it should be fixed to the wall with at least four screws.
If the wind is very strong at the construction site, it is necessary to tie it vertically. In areas with high wind power, it may be required to directly bind rafters and truss rafters to the wall. The top of the harness should be nailed to the board on the wall, while the rafters depend on how they are designed. When fixed to the wall, the strap must be longer than the specified number of bricks and at least two fasteners must be engaged with the last complete brick at the bottom of the strap.
