Large-span roof construction is very important for buildings, so what is the process of using steel structure for large-span roof construction? Is there anything to pay attention to? China SAFS steel structure takes everyone to learn together. The space frame manufacturer analyzes the steps of steel structure roof construction:
①When laying glass wool roll felt, the veneer should face the indoor side, perpendicular to the purlin, leave about 20 cm of rolled felt at the eaves of one side, and fix it on the outermost purlin with a special clamp or double-sided tape;
② Ensure that the roll is aligned and tensioned when unwinding, lay the glass wool roll felt on the other side of the eaves, also leave 20 cm of roll felt, and fix it on the outermost purlin with a special clamp or double-sided tape;
③ The two rolls of cotton are connected together by binding with a stapler on the veneer flash;
④ Install the roof color steel plate, remove the fixtures at the eaves on both sides, and use the reserved 20 cm veneer to close the edge of the glass wool;
⑤ Pay attention to maintaining the tension and alignment of the glass wool roll felt, and the joint between the rolls is tight. When the longitudinal overlap is required, the overlap joint should be arranged at the purlin;
⑥ According to the needs of the project, in order to avoid the generation of cold bridges, some hard thermal insulation materials can be considered on the purlins.
