Description

A steel structure gable joint connection structure

technical field

The utility model relates to the technical field of steel structure buildings, in particular to a steel structure gable node connection structure.

Background technique

In steel structure buildings, the metal roof is mainly composed of metal plates, various metal edges and flashings, and lighting panels. The connection between them is mainly by plate rib locking and screw fastening, and the waterproof is mainly realized by sealant. Since the roof system is in contact with the external environment and the main structure is in contact with the internal air environment, they experience inconsistent temperature changes in winter, summer and day and night. For large roofs, it is easy to accumulate temperature internal force and cause damage to connections and seals, resulting in water leakage. The roof must be connected to the wall panels at the gables through flashing boards for sealing and wind resistance.

In the traditional gable flashing board, one end of the flashing board is usually fixed on the exterior wall board, and the other end is folded and fixed on the roof board with screws. Roof panels can slide under large temperature differences, but wall panels must be fully fixed to the main structure. As the temperature changes, due to the inconsistent deformation of the roof panel and the wall panel, the gable flashing plate will generate shear force along the length direction, and the entire gable joint steel structure will undergo expansion and contraction deformation, resulting in damage at the screw connection, and rainwater will Seep into the house along the gap, and the problem of water leakage will follow. Even if the sealant is used to seal the gap, the sealant will be exposed to the outside for a long time, and it will soon lose its sealing effect after being exposed to wind and sun, causing roof leakage.
