Abstract

The invention provides a connecting structure of a prefabricated concrete wall body and belongs to the technical field of building structures. The connecting structure of the prefabricated concrete wall body comprises a first prefabricated concrete wall body and a second prefabricated concrete wall body, wherein longitudinal through holes are arranged at the positions close to the end faces of the first prefabricated concrete wall body and the second prefabricated concrete wall body, and the end faces of the first prefabricated concrete wall body and the second prefabricated concrete wall body are correspondingly provided with a plurality of transverse grooves. The end face of the first prefabricated concrete wall body is provided with a first U-shaped steel bar protruding outward from the inside of the wall body, the end face of the second prefabricated concrete wall body is correspondingly provided with a second U-shaped steel bar protruding outward from the inside of the wall body, the intersected portions of the first U-shaped steel bar and the second U-shaped steel bar form a rectangular steel bar ring, and cast-in-place concrete is arranged in spaces among the transverse grooves, the longitudinal through holes and the prefabricated concrete wall bodies. The connecting structure can improve integrity of an assembled monolithic concrete structure and the performance of a building structure.

Description

technical field [0001] The invention belongs to the technical field of building structures and relates to a connection structure of prefabricated concrete walls. Background technique [0002] Prefabricated concrete structure is suitable for industrialization and is the development direction of housing industrialization. The joint connection structure between prefabricated components in precast concrete structures determines the overall performance of the structure. The existing prefabricated concrete structure nodes are generally the weak link of the assembled integral concrete structure, which affects the mechanical performance, and the structure is relatively complicated, and it is easy to crack and affect the performance during the use stage. Contents of the invention [0003] The invention solves the problem of weak prefabricated wall joint connection in the traditional prefabricated concrete structure, and provides a connection structure of the prefabricated concrete...
