Problems solved by technology

[0004] (1) The vertical flat plate (steel plate) bolt connection node of the beam only has vertical stiffness and bearing capacity, and the load bearing capacity is small, which is only applicable to the case where there is a wall plate under the beam
[0005] (2) When there is no wall panel under the beam or no connection between the floor and the beam, the safety of large-span structures and complex structures cannot be ensured
[0006] (3) In a narrow space where the length is only 300mm, the minimum width of the upper section is 120mm, and the minimum width of the lower section is 220mm, due to construction errors, it is difficult to ensure the construction accuracy of the joint connection and reduce the structural safety
[0007] (4) The connection nodes of the beams need external templates for wet joint pouring concrete connection, which cannot be reused

Abstract

The invention discloses a beam joint structure for horizontal bending resistance of a bolt-connected fully-assembled reinforced concrete wallboard, and relates to the technical field of assembled concrete structures, in particular to a beam joint structure for horizontal bending resistance of a reinforced concrete wallboard assembled in a bolt connection mode. The beam joint structure comprises ajoint assembling part, a beam end steel plate, an anchoring structure and a assembly component; the joint assembling part and the anchoring structure are welded on the two sides of the beam end steelplate correspondingly to form the beam joint structure; the anchoring structure is prefabricated in beam concrete; two opposite beam joint structures are fixedly connected through the connecting assembly, so that connection and assembling with large horizontal bending resistance of the assembled reinforced concrete wallboard structure are realized. By means of the technical scheme, the problems inthe prior art that the horizontal bearing capacity of an unsupported wallboard is small, large-span and high-precision construction cannot be realized, and repeated use cannot be realized are solved.

Description

technical field [0001] The invention relates to a bolt-connected fully assembled reinforced concrete wall plate horizontal bending-resistant beam joint structure, which relates to the technical field of assembled concrete structures, in particular to a bolt-connected reinforced concrete wall plate horizontal bending resistant beam joint structure. Background technique [0002] Prefabricated concrete structures have been widely used at home and abroad because of their advantages such as high production efficiency, convenient assembly, green energy saving and environmental protection. The low-story fully-fabricated bolt-connected wall panel reinforced concrete structure is increasingly playing a good technical and economical advantage. Among them, the modular unitized wall panels that use wall panels with both vertical load-bearing components and space division functions are connected to each other with horizontal bolts in the horizontal direction, and connected to beams (or f...
