How to build the roof of rural light steel villa? |The most detailed explanation of the light steel roof construction process in history! -wellcamp light steel villa manufacturers
Roof skeleton installation 1. After the roof skeleton assembly is completed, the roof skeleton assembly and construction can be started. 2. 2-4 people jointly lift a roof frame and move it to the designated location for installation. 3. For a roof skeleton, adjust the bottom guide beam first, and the bottom guide beam and the top guide beam of the wall are arranged to overlap. Then use self-drilling screws to temporarily fix it. Then adjust the verticality of the whole skeleton, and use the magnetic force line pendant to adjust the verticality. After installing one roof skeleton, use light steel rods to temporarily fix it first to ensure that other roof skeletons will not move during construction. 4. Then install other roof skeletons from side to side in accordance with the 'Roof Frame Installation Details' to ensure that the position and verticality of each truss meet the requirements. 5. The support system includes: upper chord support, lower chord support, vertical support and other supports. In addition to temporary reinforcement rods during the installation of the roof skeleton, it is necessary to install the support system in time to ensure the safety and stability of the structure. 6. Install all roof trusses from side to side in a similar manner. 7. After the roof truss is completed, see the following picture: 2. After the roof structure plate is installed and reinforced, the cornice is adjusted to ensure that the cornice is level, and then the roof structure plate is installed and constructed. The structure plate adopts imported osb plate. 1. Tool preparation: hand-held cutting machine, hand-held electric drill, self-drilling screws, etc. 2. Structural board installation 2.1 Imported osb board size is 2440×1220mm, the floor beam spacing is 610mm, just one osb board is placed for every 3 sets of roof trusses to ensure that each board can be overlapped with the roof truss beam. 2.2 After laying the osb board, use a hand-held electric drill to set the self-drilling screws to fix it. 2.3 The roof structural plates should be laid in staggered joints as much as possible. If there is no keel at the lap joint, steel straps must be added to meet the requirements of nailing, so as to enhance the strength of the roof structural plate. 2.4 Because the construction of the roof structural board is a high-altitude operation and the roof is inclined, it is necessary to temporarily fix short light steel members on the laid structural board to provide work support and temporary stacking of small tools for the construction workers. 2.5 The self-drilling screws shall be set according to the requirements of Table 8.2: the position and spacing of the self-drilling screws are allowed deviation!
