The foundation bottom plate reinforcement reverse construction method of the present invention belongs to the technical field of building construction and structure reinforcement and transformation. The present invention first pours a new foundation bottom plate on the top of the original foundation bottom plate, reserves pits around the original load-bearing columns during pouring, and the new foundation Rebar joints are reserved at the end of the bottom plate reinforcement close to the original load-bearing column, and then the original load-bearing column is topped, and then the original load-bearing column and the original foundation floor directly below the pit are removed, and the position of the original foundation floor directly below the pit is Concrete is poured again, and the steel mesh is bound in the pit, and the steel mesh is connected with the steel joint. Concrete is then poured in the pit and finally new load-bearing columns are installed. The invention effectively solves the problem of difficult installation when the positions of the new structural column and the old structural column conflict, and improves the construction efficiency. It also improves the integrity of the concrete at the bottom of the structural column, improving safety.
Description
technical field [0001] The invention relates to the technical field of building construction and structure reinforcement and transformation, in particular to a reverse construction method for foundation floor reinforcement. Background technique [0002] With the acceleration of urban construction and renewal, some old buildings can no longer meet the functional requirements. There are more and more underground space reconstruction and foundation reinforcement projects, and the application of reverse construction technology is becoming more and more extensive. However, the following two problems may occur during the foundation reinforcement process: [0003] 1. The position of the load-bearing column (box-shaped steel column) of the new structure partially coincides with the position of the load-bearing column (concrete column) of the old structure. The existence of the old structural column affects the construction of the new structural column, and the direct demolition of t...
