Multi-storey building with prefabricated parts and its semi-prefabricated construction method

Abstract

The invention discloses a multistoried building with prefabricated members and a semi-prefabricating construction method of the multistoried building. The multistoried building comprises prefabricated outer walls (1), cast-in-place wall bodies (2), semi-prefabricated slabs (31), cast-in-place slabs (32), prefabricated ladders (6), prefabricated bathrooms (7) and prefabricated kitchens (8), wherein the upper end and the lower end of each prefabricated ladder (6) are provided with installation holes (61) for grouting mortar, exposed reinforced steel bars are fixedly arranged on slabs connected with the upper end and the lower end of each prefabricated ladder (6) and are inserted into the corresponding installation holes (61) and fixed through grouting the mortar; and horizontally-exposed reinforcing steel bars are pre-arranged on the bottoms of the prefabricated bathrooms (7) and the prefabricated kitchens (8) and are mutually connected with reinforcing steel bars in the cast-in-place slabs (32). The multistoried building and the semi-prefabricating construction method thereof have short construction period, so that a standard storey can be built in four days, the idle time of workers is reduced to be minimum, and the quality standard is more uniform.

Description

technical field [0001] The invention relates to a multi-storey building and a construction method thereof, in particular to a multi-storey building with prefabricated components and a semi-prefabricated construction method thereof. Background technique [0002] In the prior art, the traditional construction method of multi-storey buildings is generally as follows: 1) first build the steel mesh for the load-bearing walls and columns, then install the formwork around the steel mesh, and then pour concrete into the formwork to form the load-bearing walls and columns; 2 ) Install the formwork and support frame for the floor slab and supporting beams, then lay steel bars for the slab and beams in the formwork, and then pour concrete into the formwork to form the floor slab and beams; 3) Remove the support frame for the next floor, press The above steps complete the construction of the upper floor of the building. The disadvantages of this traditional construction method are: bui...

AI Technical Summary

Problems solved by technology

The disadvantages of this traditional construction method are: building buildings layer by layer, not only the construction period is long, the construction cost is high, but also the construction site is seriously polluted by noise and dust, and it is difficult to ensure that the buildings have uniform quality standards

But even so, the construction volume of toilets, kitchens, stairs, etc. in each suite in the building is still very large, so the construction period is still unsatisfactory.
