technical field

The utility model belongs to the technical field of building structures, in particular to a vertical connection node of a superimposed shear wall of equal thickness.

Background technique

The shear wall structure can prevent the structure from shearing (shearing) damage due to its strong ability to withstand horizontal loads and vertical loads (gravity) caused by wind loads or earthquakes; In the building, it does not affect the use function of the room, so the shear wall structure is the preferred structural form of high-rise residential buildings.

In recent years, prefabricated buildings have developed rapidly. Composite shear walls replace traditional cast-in-place shear walls, which can reduce the workload of on-site formwork, steel bar binding, and cast-in-place concrete. Prefabricated buildings are formed by different prefabricated components assembled on site, which will inevitably lead to connections between components. Prefabricated components are mechanized in the factory, and the quality is easy to guarantee. The rationality of the connection between components directly determines the Whether the overall structure is safe or not is also a difficult problem facing the development of prefabricated buildings. In the laminated shear wall structure, the vertical connection of the laminated shear wall is extremely critical.

In view of this, the applicant provides a vertical connection node for laminated shear walls of equal thickness, and this case arises from it.
