Method for reinforcing space concrete beam column node by sticking fiber cloth

Abstract

The invention relates to a technique stabilizing room concrete pillars joint points by pasting fiber cloth. First add element concrete at the bases of the pillars around the core section in pillar communication area, namely the concrete haunch, forming the triangle concrete blocks. Then paste fiber cloth on the surface of the blocks and the pillars joining the blocks and the joints main bodies together.

Description

technical field [0001] The invention relates to building reinforcement engineering, in particular to a structure for reinforcing spatial concrete beam-column joints with pasted fiber cloth. Background technique [0002] Concrete beam-column joints are a common part of building structures. Please refer to the schematic diagram in Figure 1. Its stress state is relatively complicated, and it bears the vertical load transmitted by the column, the bending moment and shear force at the beam end, and is one of the frame structures. An important part, and the core area of ​​the intersection area of ​​beams and columns is even more important. [0003] When the planar frame joints are reinforced by sticking fiber cloth, that is, the sheet form of fiber-reinforced composite material, fiber cloth with different directions and different layers can be pasted on beams, columns, and core areas as required, as shown in Figure 2. [0004] But for space nodes, the intersection of cross-shaped...

Problems solved by technology

[0005] The task of the present invention is to provide a structure for pasting fiber cloth to reinforce space concrete beam-column joints, which solves the problem in the prior art that the concrete in the core area of ​​space joints cannot be directly pasted with fiber cloth for reinforcement and thus cannot improve the performance of the entire joint
