Description

Building structure column reinforcement structure and reinforcement method

technical field

The invention relates to the field of building reconstruction and reinforcement, in particular to a building structure column reinforcement structure and a reinforcement method, which are suitable for replacement concrete reinforcement method, posted steel plate reinforcement method, enlarged section reinforcement method and outer profile steel reinforcement method.

Background technique

The development process of structural engineering at home and abroad shows that when the engineering construction reaches a certain stage, the maintenance and reconstruction of the engineering structure will become the main construction method. Due to the self-weight of the completed building and the existence of the live load at the non-renovation position, the structural column has already assumed a large load during the reinforcement and transformation. In the reconstruction process, in order to eliminate the adverse effect on the reinforcement effect caused by the stress lag when reinforcing the structural column, or to avoid the insufficient bearing capacity of the adjacent members caused by the change of the force transmission path when the structural column is replaced, it is necessary to unload the structural column first. Reinforce and rebuild.

At present, the commonly used unloading methods include angle steel support method, vertical pole support method, joist replacement method and so on. The joist-to-column method does not provide support, but applies prestress to the upper beam of the column to be replaced or installs a superimposed beam for support, so as to achieve the purpose of unloading. And the construction technology content is high. Relatively speaking, the support unloading method is the most common. However, the support provided must not only facilitate the adjustment of the internal force so as to transfer the load borne by the supported column according to the design requirements, but also must be easy to operate. The angle steel support method is widely used in construction, and the structural column bears part or all of the force borne by the angle steel. An optimization of the support, the bottom is equipped with a top support, and the vertical pole can be adjusted to rise and fall, but it requires multiple vertical poles to work together, and there are disadvantages such as inconvenient application of support force and complicated operation.

Using the above-mentioned traditional unloading method for structural columns, after the structural columns are reinforced by the enlarged section reinforcement method and the outsourcing steel reinforcement method, the used angle steel supports and vertical rod supports need to be dismantled after unloading, which is time-consuming and labor-intensive.
