Reverse building board construction structure and construction method thereof

Abstract

The invention discloses a reverse building board construction structure and a construction method thereof. The structure comprises temporary steel supports and further comprises a cushion layer, a short framed bent and a formwork which are arranged inside a foundation pit from bottom to top in sequence. The temporary steel supports penetrate through the short framed bent at intervals in the horizontal direction. The two ends of the temporary steel supports are respectively and fixedly connected with a vertical structure of the foundation pit. The foundation pit is excavated to the elevation X, and the formula X=Y-r-d is met, wherein Y represents the board bottom elevation of a reverse building board, r represents the sum of the height of the short framed bent and the height of the formwork, and d represents the thickness of the cushion layer. The temporary steel supports are utilized and can effectively control the deformation of the foundation pit before the reverse building board is achieved, and due to the fact that the method that the combination of the short framed bent and the cushion layer is used for supporting the reverse building board is utilized, the integral pouring of the reverse building board and a board underbeam can be achieved, the horizontal supporting force of the reverse building board and the beam integral can be improved, and the deformation of the foundation pit can be effectively controlled. Due to the fact that the short framed bent does not need to be erected from a first layer of floor on the lower portion, the erecting time of the short framed bent can be greatly shortened, needed materials can be greatly reduced, and construction efficiency is improved.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to an upside-down slab construction structure and a construction method thereof. Background technique [0002] At present, there are two mainstream floor construction methods: the first is to directly pour the floor (such as the base plate, etc.) on the cushion, which is relatively simple and economical to construct; Pouring floor slabs and beams, the construction is complex, takes a long time and has high potential safety hazards. [0003] The first method is pouring directly on the cushion, and this construction technology can fully meet the requirements for the straight method. However, when it comes to upside-down or semi-upside-down slab construction, that is, when pouring upside-down slabs, pouring directly on the cushion cannot meet the requirements of the upside-down slab structure and the simultaneous construction of beams and slabs. For the upside-down me...

Problems solved by technology

However, when it comes to upside-down or semi-upside-down slab construction, that is, when pouring upside-down slabs, pouring directly on the cushion cannot meet the requirements of the upside-down slab structure and the structural requirements of beams and slabs at the same time

For the upside-down method, when the upside-down slab is poured, the construction of the lower floor has not yet started, so the bent method cannot meet its construction conditions
