Construction structure for horizontal spliced seams of vertical joints of sandwich thermal insulation wall

Abstract

The invention relates to a construction structure for horizontal spliced seams of vertical joints of a sandwich thermal insulation wall. One gap is reserved between a lower internal wall and an upperinternal wall, one end of a composite floor slab is placed on the lower internal wall, the height of first concrete poured in a lower thermal insulation wall is located at the floor elevation position, the first concrete and a cast-in-place floor slab above the composite floor slab are of an integrated structure, and the floor elevation position is lower than the lower ends of the upper internal wall and an upper external wall; and a space between the floor elevation position and the bottom of the upper internal wall is subjected to form sealing by using square battens, the square battens arefixedly connected with the upper internal wall and the first concrete, and second concrete is poured into an upper thermal insulation wall. The construction structure for the horizontal spliced seamsof the vertical joints of the sandwich thermal insulation wall simplifies the form erecting procedure of an outer side formwork, improves the construction convenience and construction efficiency of the horizontal spliced seams of the vertical joints of the sandwich thermal insulation wall, meanwhile, the waterproof and thermal insulation performance of the spliced seam is improved, the external spliced seams are located at the floor elevation or above and form an internal-external height difference with internal plate spliced seams, and floor elevation concrete pouring is facilitated.

Description

technical field [0001] The invention relates to a joint structure of a sandwich thermal insulation wall, in particular to a construction structure of vertical joints and horizontal joints of a sandwich thermal insulation wall, belonging to the technical field of sandwich thermal insulation walls. Background technique [0002] Since the external thermal insulation structure has relatively serious fire prevention and durability problems (the service life is 10 to 15 years), the internal thermal insulation structure is easily damaged by the interior decoration. Therefore, a sandwich thermal insulation shear wall system that places thermal insulation materials between the inner and outer leaf concrete slabs has received extensive attention abroad and has been maturely applied, forming a mature system. With the development of prefabricated buildings, the existing technology has gradually begun to do some research on the sandwich shear wall system, but there are still a lot of def...

AI Technical Summary

Problems solved by technology

In the prior art, the process of forming the outer formwork of the sandwich insulation wall is cumbersome, the construction is difficult at the joints, the waterproof and thermal insulation performance of the joints is poor, the construction efficiency is low, and there is a risk of grout leakage; at the same time, it is inconvenient to pour concrete at the floor level
