Abstract

The invention provides an L-shaped precast concrete wall connection, belonging to the technical field of the building structures. The L-shaped precast concrete wall connection comprises a first precast concrete wall and a second precast concrete wall, wherein longitudinal penetrating holes are formed on the precast concrete walls on the connection side in the vicinity of end faces and a plurality of transverse grooves crossing with the longitudinal holes are oppositely formed on the end faces; first and second thin plates extend from the connection-side end faces of the first and second precast concrete walls, respectively; a first horizontal reinforcing steel bar extending to the edge of the first thin plate is arranged in the first precast concrete wall, while a second horizontal reinforcing steel bar and a first embedded column stirrup both extending to the edge of the second thin plate are arranged in the second precast concrete wall; cast-in-place concrete is poured in the space formed by the first and second thin plates, the longitudinal holes and the transverse grooves; and a second embedded column stirrup and a vertical reinforcing steel bar are arranged in the cast-in-place concrete. The L-shaped precast concrete wall connection is capable of improving the integrity of the assembled integrated concrete structure and improving the performance of the building structures.

Description

technical field [0001] The invention belongs to the technical field of building structures and relates to an L-shaped prefabricated concrete wall connecting node. 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 is easy to crack 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 an L-shaped prefabricated concrete wall connection node. The L-shaped prefabricated concrete wall connection node proposed by ...
