本文详细介绍了某砖混结构底层变大空间的加固与改造在该工程中的应用。为满足大空同平面尺寸的建筑功能,将多层砖混结构改建成局部框架结构,可采用托梁换柱技术。但在具体的各环节的质量均应接要求严格把关,才能达到预期的效果。 This paper introduces in detail the reinforcement and reformation of the larger space of a masonry concrete structure in the project. In order to meet the building function of large space with the same size, the multi-story brick-concrete structure is transformed into a partial frame structure, and the joist column-changing technique can be adopted. However, in all aspects of the quality of the specific requirements should be strictly checked in order to achieve the desired results.
