Description

Connection structure between GRC composite thermal insulation exterior wall panels and main structure

technical field

The utility model relates to a connection structure between a GRC composite thermal insulation outer wall board and a main body structure.

Background technique

Compared with traditional masonry walls, prefabricated new GRC composite thermal insulation exterior wall panels have better integrity and strength, and compared with traditional shear walls, they have better ductility. The connection methods between the prefabricated new GRC composite thermal insulation exterior wall panels and the main body mainly include external hanging type and side connection type. The external hanging type is mainly connected to the beam by the upper part of the wall panel through dry connection, and the side and bottom edges are only used as limiters. Connection, the role of the wallboard is hardly considered in the design, and it is likely to cause the overall shedding and collapse of the wallboard during an earthquake. The side-connected type mainly relies on the side of the wall panel to be connected to the column through wet connection, and the lower side only has a limited connection, so it greatly increases the rigidity of the structure like a masonry wall, and it is easy to cause severe cracking of the wall panel during an earthquake and destroy. Therefore, there is a need for a new connection method so that the prefabricated new GRC composite thermal insulation wall panels will not be severely damaged like masonry walls, will not affect the ductility of the frame, and have certain seismic performance. The utility model uses silicone structural sealant to bond prefabricated new GRC composite thermal insulation exterior wall panels, beams, and columns instead of traditional mortar-bonded masonry, so that when the structure is damaged, the silicone structural sealant is used to bond No serious damage will occur to the new GRC composite thermal insulation exterior wall. The beams and columns in the new GRC composite thermal insulation exterior wall panels and the frame structure are connected by embedded fixings, which improves the overall rigidity of the structure. In this way, the silicone structural sealant, embedded fixings, and concrete steel nails form a combination of rigidity and flexibility. Some structures can not only protect the new GRC composite thermal insulation exterior wall panels, but also give full play to the advantages of prefabricated components.
