Description
Technical Field
The invention relates to the field of building construction, in particular to a cast-in-place concrete built-in heat-insulation wall structure and a construction method.
Background
The cast-in-place concrete built-in heat insulation wall body is structurally composed of an inner wall layer, a heat insulation layer and an outer wall layer, wherein the heat insulation layer is provided with a plurality of connecting pieces. The rod body of the connecting piece of the existing cast-in-place concrete built-in heat insulation wall body is a solid rod. In addition, the inner wall layer and the outer wall layer of the cast-in-place concrete built-in heat insulation wall body need to be fastened by using the split bolts before pouring, so that the inner template and the outer template are positioned under the synergistic effect of the pulling force of the split bolts and the supporting force of the connecting piece. In order to enable the split bolts to pass through, through holes need to be specially arranged on the heat insulation layer. Usually, 6-8 connecting pieces and 9 split bolts need to be arranged per square meter, namely 15-17 through holes need to be formed in the heat insulation layer per square meter, after pouring is completed, the through holes penetrate through the inner wall layer, the heat insulation layer and the outer wall layer, the overall structure of the cast-in-place concrete built-in heat insulation wall body can be damaged by the numerous through holes, heat loss is increased, and the heat insulation performance of the cast-in-place concrete built-in heat insulation wall body is reduced.
The existing cast-in-place concrete built-in heat insulation wall body, such as a CL wall body (composite heat insulation steel bar welded net rack concrete shear wall), is complex in structure, labor-consuming and time-consuming in installation and construction due to the fact that a steel wire mesh sheet is arranged in an outer wall layer of the existing cast-in-place concrete built-in heat insulation wall body. And the use of the steel wire mesh sheet leads to high cost of the cast-in-place concrete built-in heat insulation wall. In addition, because the distance between the steel wire mesh and the heat insulation layer is small, a vibrating rod cannot be used for vibrating during pouring, because the outer wall layer can only use Self-compacting Concrete (Self compacting Concrete or Self-compacting Concrete for short SCC) when pouring, namely Concrete which can flow and compact under the action of Self gravity, can completely fill the formwork even if compact steel bars exist, can obtain good homogeneity and does not need additional vibration), the durability of the Self-compacting Concrete after hardening is very limited, meanwhile, the self-compacting concrete usually has air bubbles, so that the strength of the self-compacting concrete is inferior to that of the conventional concrete, the high-flow self-compacting concrete has slightly larger drying shrinkage compared with the conventional concrete, and the serious defect of the self-compacting concrete causes the low strength of the whole concrete wall, and because the inner wall layer uses conventional concrete, the use of self-compacting concrete leads to the whole integration degree of concrete wall body to be low.
