Color steel tile steel frame or roof truss, purlin and roof panel are important components of color steel roof. The installation method of color steel plate is directly related to the bearing capacity of steel frame or roof truss, purlin and roof panel.
The photovoltaic support of color steel tile can be directly connected with the roof panel at the purlin, or the connection between the connector and purlin through the roof panel can be selected.
The number and size of various connectors and fasteners can be obtained by static calculation analysis and design construction.
1) When the color steel tile steel frame, roof truss and purlin can meet the design requirements and the roof panel steel is large, this method is based on the correct installation conditions. The photovoltaic support is connected with the roof panel by selecting connectors, and the position is kept as close as possible to the purlin.
2) The color steel tile steel frame, roof truss and purlin can meet the design requirements, but when the roof plate steel is small and the deformation is large, this kind of color steel roof mainly presents some places with low requirements, such as car shed, bus waiting hall and breeding farm.
3) Only the steel frame or roof truss of color steel tile can meet the design requirements, and the bearing capacity of purlin and roof panel is small. In this deployment method, the connector is selected to connect with the steel frame or roof truss. The detailed connection and installation method is the same as that of the support and purlin penetrating the roof panel.
4) There is still a connection method for color steel tile, which is to cut the roof panel at the position of the unchanged support and connect it to the roof steel beam through the steel column.
The above is the summary of the deployment method of photovoltaic support for the key color steel roof. For the connector penetrating the roof, it must be equipped with waterproof gasket or treated with sealing structural adhesive to ensure the waterproof strength.
If the color steel tile steel frame or roof truss, purlin and roof panel can not meet the design requirements, the name of photovoltaic power station cannot be built on the original roof. Before the support design, the steel frame or roof truss, purlin and roof panel of the original roof must be accurately calculated.
