Problems solved by technology

The prefabricated structure has the advantages of factory production and simple on-site construction. However, according to existing research and practice, the existing prefabricated structure or prefabricated-integral structure has poor integrity and earthquake resistance and partial construction of cast-in-place concrete. The disadvantage of low industrialization degree, which limits the application of prefabricated structures

Embodiment 1

[0017] figure 1 As shown, the present invention is used for the assembly-cast-in-place dense column structure of the multi-storey residential building of the shear wall system. The slab consists of 1. The cavity diaphragm thickness of the prefabricated building hollow wall form 8 is 30mm. The prefabricated building hollow wall formwork 8 is installed by a crane, temporarily fixed after correction, and the cast-in-place dense columns 7, cast-in-place corner columns 5, cast-in-place beams 4 and floor 1 are connected with steel bars and formwork supports, and then concrete is poured. Form the overall structure of dense columns.

[0018] In order to form the assembly-cast-in-place dense column structure, the technical scheme adopted is:

[0019] (1) Factory prefabricated building hollow wall formwork

[0020] figure 2 As shown, the prefabricated building hollow wall formwork 8 is a modularized permanent formwork, its area is equivalent to a single shear wall, its height and ...

Embodiment 2

[0030] The present invention is used in the assembly-cast-in-place dense column structure of a small high-rise residential building with a shear wall system, including a prefabricated building hollow wall form 8, a cast-in-place dense column 7, a cast-in-place corner column 5 and a cast-in-place beam 4, and a cast-in-place floor slab 1 composition. The cavity diaphragm thickness of the prefabricated building hollow wall form 8 is 60mm. The prefabricated building hollow wall formwork 8 is installed by a crane, temporarily fixed after correction, and the cast-in-place dense columns 7, cast-in-place corner columns 5, cast-in-place beams 4 and floor 1 are connected with steel bars and formwork supports, and then concrete is poured. Form the overall structure of dense columns.

[0031] The concrete construction process of embodiment 2 is the same as embodiment 1.

[0032] By adopting the assembly-cast-in-place dense column structure, the industrialized construction of the shear w...

Abstract

The invention belongs to the field of construction engineering, and relates to construction technology of building structures, in particular to the technology of adopting the construction method of assembly-cast-in-place to realize the dense column structure used in residential buildings with shear wall system. It is suitable for multi-storey and small high-rise residential buildings with shear wall system, and can also be used for shear wall structures of other industrial and civil buildings. In the present invention, dense columns (7) are arranged in the cavity of the prefabricated building hollow wall formwork (8) and connected with cast-in-place corner columns (5), cast-in-place beams (4), floor slabs (1) and other components to form an assembled-on-site Poured dense column structure. Adopting the assembly-cast-in-place dense column structure with good structural performance of the present invention, in the construction of multi-storey and small high-rise residential buildings of the shear wall system, the cast-in-place concrete wall does not need traditional wall formwork, which improves the assembly-type concrete structure. The prefabrication rate of the structure realizes the industrialized operation on the construction site, which can be used in the construction of industrialized houses, and effectively overcomes the defects of the current prefabricated concrete structure.

Description

technical field [0001] The invention belongs to the field of construction engineering, and relates to construction technology of building structures, in particular to the technology of adopting the construction method of assembly-cast-in-place to realize the dense column structure used in residential buildings with shear wall system. It is suitable for multi-storey and small high-rise residential buildings with shear wall system, and can also be used for shear wall structures of other industrial and civil buildings. Background technique [0002] With the promotion of housing industrialization in my country and the gradual deepening of green and environmental protection construction, the use of prefabricated construction technology has become one of the construction methods. The prefabricated structure has the advantages of factory production and simple on-site construction. However, according to existing research and practice, the existing prefabricated structure or prefabri...
