Problems solved by technology

At present, in prefabricated concrete buildings, the area of ​​prefabricated concrete inner wall panels is generally large, which is inconvenient for transportation and hoisting. At the same time, the size of the inner wall panels of each building is different, and the degree of standardization is low, which is not conducive to large-scale production.

Embodiment Construction

[0038] like Figure 1-Figure 15 As shown, the sandwich type prefabricated concrete inner wall panel structure, production and assembly method of the present invention are as follows:

[0039] (1) Structure and manufacturing process of sandwich precast concrete interior wall panels

[0040] like figure 1 As shown, the single-layer reinforcement mesh 1 (reinforcement mesh for short) of the concrete inner wall panel is formed by vertically arranging criss-cross thin steel bars with a diameter of 4 mm, and the spacing of the thin steel bars is 150 mm.

[0041] like Figure 2-Figure 3 As shown, the non-threaded T-screw 4 is welded with the steel plate 2 with holes to form the bottom formwork 3 of the concrete inner wall panel. On the other side of the steel plate 2, the nut is welded to the steel plate with holes 2 through holes, and the welding seam is located in the hole of the steel plate 2 with holes, so as to prevent the weld between the bottom template 3 and the nut from a...

Abstract

The invention relates to the field of prefabricated concrete structure construction, in particular to a sandwich type prefabricated concrete inner wallboard structure, manufacture and assembly method.A template structure is used for pouring concrete, a concrete inner wall boardsingle-layer reinforcing mesh is arranged in a prefabricated concrete inner wall board,and the concrete inner wall boardsingle-layer reinforcing mesh is formed by criss-cross steel bars vertically arranged;two rows of reserved bolt holes are formed in parallel in the prefabricated concrete inner wall board in a penetration manner, and two rows of supporting embedment pieces are arrangedin parallel on the back face of the prefabricated concrete inner wall board. According to the sandwich type prefabricated concreteinner wallboard structurewith smaller width, the manufacture and the assembly method, the installation is simple, the arrangement is flexible, the degree of standardization is high, and the process ofbuilding industrialization is promoted.

Description

technical field [0001] The invention relates to the field of prefabricated assembled concrete structure buildings, in particular to a structure, production and assembly method of a sandwich type prefabricated concrete inner wall panel. Background technique [0002] The prefabricated concrete structure has the advantages of fast construction speed, energy saving and environmental protection, and small amount of wet work on site. It has developed rapidly in China in recent years. The inner wall panel is an important component and maintenance structural member of the fabricated concrete structure. At present, in prefabricated concrete buildings, the area of ​​prefabricated concrete inner wall panels is generally large, which is inconvenient for transportation and hoisting. At the same time, due to the different sizes of the inner wall panels of each building, the degree of standardization is low, which is not conducive to large-scale production. In order to solve the above pro...
