They are vertical connection and horizontal connection.
Longitudinal connection: The longitudinal lap of the corrugated steel plate should be located in the purlin or wall beam, and both plates should be extended to the supporting member. The length of the lap shall be 350mm for the high-wave roof slab; The low-wave roof panel with roof slope ≤10 is 250mm, and the low-wave roof panel with roof slope > 10 is 200mm. The wall panels are 120mm. When roofing is bonded, a long sealing tape should be installed between the plate joints.
Horizontal connection: generally can be divided into lap, bite edge, buckle three ways. When the building has special functions and requirements, the ordinary connection method can also be improved, and the connection method for different special requirements can be researched and developed for practical projects. Secondly, the transverse lap direction of the molded steel plate should be the same as the dominant wind direction, and the lap is not less than one wave. The overlapping part is provided with a long sealing tape.
