Abstract

The invention provides an L-shaped prefabricated concrete wall connection joint, and belongs to the technical field of construction structures. The L-shaped prefabricated concrete wall connection joint comprises a first prefabricated concrete wall body and a second prefabricated concrete wall body, wherein a longitudinal through hole is formed in the portion, on the joint side and close to the end face, of the first prefabricated concrete wall body, a longitudinal through hole is formed in the portion, on the joint side and close to the end face, of the second prefabricated concrete wall body, a plurality of transverse grooves are formed in the end face on the joint side of the first prefabricated concrete wall body, a plurality of transverse grooves are formed in the end face on the joint side of the second prefabricated concrete wall body, the top portion of each transverse groove extends into the portion, inside the corresponding longitudinal hole, of the corresponding wall body or intersects with the corresponding longitudinal hole, the first prefabricated concrete wall body and the second prefabricated concrete wall body extend on the end faces of the joint sides to form a first sheet and a second sheet respectively, an edge joint is reserved at the joint of the first sheet and the second sheet, and cast-in-place concrete is arranged in the space defined by the first sheet and the second sheet, the longitudinal holes and the transverse grooves. According to the L-shaped prefabricated concrete wall connection joint, the integrality of a prefabricated overall concrete structure can be improved, and performance of the construction structure can be improved.

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 ...
