Lamination transitional construction method for concrete heat insulation curtain wall

Abstract

The invention belongs to the field of buildings, and provides a lamination transitional construction method for a concrete heat insulation curtain wall. The lamination transitional construction method comprises a cast-in-place concrete heat insulation curtain wall construction process and a rear concrete heat insulation curtain wall construction process. The method comprises the steps that a heat insulation plate of the cast-in-place concrete heat insulation curtain wall is fixed, a main structure formwork is erected, an EPS plate is arranged in the position of a cast-in-place concrete panel at the interface of the rear concrete heat insulation curtain wall in a filled mode, concrete is not poured into the cast-in-place concrete panel at the position of the EPS plate temporarily, and an overlapped notch is formed; after the filling wall is poured, a heat insulation plate of the rear concrete heat insulation curtain wall and a heat insulation plate of the cast-in-place concrete heat insulation curtain wall horse tooth stubbles which are staggered; a reinforcing mesh is hung on the heat insulation plate of the rear concrete heat insulation curtain wall, and concrete is smeared on the heat insulation plate of the rear concrete heat insulation curtain wall. According to the method, construction cracks at the interface are scattered within the area of a certain width on the junction of the interface, so that the interface seam width is decreased to be within the tolerance range, and the durability of the concrete heat insulation curtain wall is guaranteed.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a laminated transition construction method for a concrete thermal insulation curtain wall. Background technique [0002] Concrete thermal insulation curtain wall is composed of concrete surface layer and thermal insulation board, and does not bear the load and function of the main structure. It includes the cast-in-place concrete thermal insulation curtain wall and the rear concrete thermal insulation curtain wall. The cast-in-place concrete thermal insulation curtain wall refers to the concrete thermal insulation curtain wall that is constructed simultaneously with the main structure, and the post-installed concrete thermal insulation curtain wall refers to the concrete thermal insulation curtain wall that is constructed after the construction of the main structure or building enclosure wall. Such as figure 1 As shown, on the exterior wall of a building, the main structu...
