Description

Technical Field

[0001] The utility model belongs to the technical field of earthquake-resistant reinforcement of buildings, in particular to an earthquake-resistant reinforcement mechanism for a concrete column. Background Art

[0002] In the field of seismic reinforcement of buildings, the reinforcement of original structural members such as beams and columns of buildings is a common method. Concrete columns are the most basic load-bearing components in various engineering structures such as houses, bridges, and hydraulic structures. They are often used as pillars of floor slabs, bridge piers, foundation columns, towers, and compression rods of trusses. In particular, upgrading and reinforcing existing production workshops requires reinforcement of the load-bearing concrete columns. In related technologies, the cross-section reinforcement method is to pour a layer of new concrete on the top of the component and add corresponding steel bars to increase the bearing capacity of the component. When pouring additional concrete in the compression zone of the component, the effective height of the component can be effectively increased, thereby improving the bending and shear bearing capacity of the component and increasing the stiffness of the component.

[0003] However, existing reinforcement methods usually involve complex construction processes and large material consumption, which leads to increased costs and reduced construction efficiency. Therefore, developing a concrete column reinforcement mechanism that can not only improve the bearing capacity of earthquake resistance, but also reduce material consumption and simplify the construction process is of great significance in the field of building earthquake reinforcement technology.
