Prefabricated part and semi-prefabricated construction method for multistory building

Abstract

The invention discloses a prefabricated part and a semi-prefabricated construction method for a multistory building. The prefabricated part comprises a prefabricated outer wall (6), the prefabricated outer wall (6) comprises a reinforced concrete wall body (61); the middles of the end surfaces of two side edges of the reinforced concrete wall body (61) are provided with a groove (611) respectively; a plurality of exposure steel bars (63) are extended out of the end surfaces of two sides of the reinforced concrete wall body (61); and the plurality of exposure steel bars (63) are fixedly connected with a steel mesh in a cast-in-place bearing horizontal wall (11) which is adjacent to and in the same layer with the exposure steel bars. The semi-prefabricated construction method comprises the following steps of: constructing the prefabricated outer wall and prefabricated floor plates; laying the prefabricated floor plates and pouring concrete on the prefabricated floor plates to form semi-prefabricated floor plates; temporarily fixing the prefabricated outer wall by using a flexible straight bar and a triangular bracket; and pouring the bearing horizontal wall. By the prefabricated part and the semi-prefabricated construction method, the construction efficiency of the multistory building can be obviously improved, the construction cycle is shortened, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the construction of a multi-storey building, in particular to a prefabricated component of a multi-storey building and a semi-prefabricated construction method for building a multi-storey building by using the prefabricated component. Background technique [0002] In order to save land resources, today's buildings, venues, and buildings generally have several or even more than ten floors. The traditional construction method of multi-storey buildings is generally as follows: 1) First build the steel mesh that forms the load-bearing wall frame, and then build the steel mesh on the periphery of the steel mesh. Formwork is installed, after which concrete is poured into the formwork to form a load-bearing wall; 2) formwork supported by a series of braces is installed to form the frame of the slab, steel bars are then laid in the formwork, and concrete is subsequently poured into the formwork to cast the formwork Floor; 3) Remove the...

Problems solved by technology

This invention patent solves the shortcomings of traditional technology such as long construction period and low construction standardization. However, since there are brackets on both sides and top of the vertical plate unit 1, the brackets on the upper and lower floors need to be accurately docked when installing the brackets. The bracket also needs to be embedded in the load-bearing cross wall 2, which will inevitably affect the construction time and increase the construction cost
