Description

[0001] Technical field: [0002] The invention belongs to the technical field of prefabricated assembled structures in civil engineering, and in particular relates to a connection structure and a construction method of a bolt-connected insertion type upper and lower prefabricated shear walls and laminated plates. [0003] Background technique: [0004] The prefabricated prefabricated structure has a series of advantages, and it is a structure worthy of vigorous promotion; the prefabricated shear wall structure is an important structure in the prefabricated structure, and has been used in engineering. The upper and lower prefabricated shear walls and the relationship between the shear wall and the floor The connection technology between them is the key issue in construction. [0005] The current construction method for the upper and lower connections of the prefabricated shear wall and the laminated slab is as follows: a certain length of steel bars are left on the upper part of...

Problems solved by technology

This connection method requires grouting on site, which has a great impact on construction and complicated procedures. The steel bars of the shear wall are not all connected, but connected at intervals. It takes time to construct the upper shear wall, which affects the construction progress

[0006] In the past, there were some studies on upper and lower prefabricated shear walls, but most of them did not consider the connection of floors, which is unrealistic. If the upper and lower prefabricated shear walls are only connected by steel bolts, this method may be damaged due to the bolt resistance under earthquake action. failure due to insufficient shear strength, and joints may fail prematurely due to insufficient strength or ductility

In addition, after the dry connection of the upper and lower prefabricated shear walls, it is difficult to achieve a reliable connection between the floor and the prefabricated shear walls
