Color steel sandwich panels can be used for roof installation by following the following steps:
Material mobilization: the manufacturer shall attach the original factory material inspection certificate. Before construction, the specification, size and thickness of color steel plate and purlin, as well as the specification, size, thickness and spare parts of all kinds of leftover materials shall be checked. It is required that the appearance of color steel plate shall be free of drag marks, color spots, wear, distortion, pollution, color difference, corner warping, etc. of the surface facial mask layer.
Lifting materials into the site: Before setting up a designated location, they must be placed in batches and classified separately. If they cannot be used immediately, they should be neatly stacked and covered with canvas or adhesive tape.
Before hanging the color steel plate on the roof truss, a baffle must be installed to prevent it from slipping; When the color steel plate is lifted to the roof truss, the hanging rod is tied to the color steel plate, and diagonal straps are added at both ends to maintain a stable and slow lifting; After hanging onto the roof and keeping the color steel stable, installation can proceed.
Installation of sandwich color steel plate: Draw corresponding installation drawings based on the materials and roof structure used. Hire professional workers to carry out accurate construction and fixing work according to installation drawings, ensuring the practicality and stability of materials.
Welding work for each chain and main beam: It is necessary to lay them in accurate positions in advance according to the installation drawings, level, straighten, and compact the main beam, and use symmetrical structural methods for spot welding work.
Installation and fixation of the top plate of the colored steel rock wool board: If the boards are fixedly connected, the spacing between each fixing point and the fixing point should be within 350 millimeters. Moreover, each plate and beam should be fixed at no less than 3 points during the connection process. And reinforcement work should be carried out in areas prone to detachment such as the roof ridge to ensure the stability of the colored steel rock wool board.
