Construction method of insulating layer of outer shear wall

Abstract

The invention provides a construction method of an insulating layer of an outer shear wall. The insulating layer comprises insulating boards, foam concrete, outer boards and insulating layer supporting frames. The construction method comprises the following steps that (1) right-angle section steel is cut into short right-angle section steel and strip-shaped right-angle section steel for standby application; (2) the insulating layer supporting frames on the joint right-angle portion of two adjacent wall bodies are manufactured; (3) multiple pieces of short right-angle section steel are fixed on the cement wall surfaces and are longitudinally and transversely arranged at intervals; (4) the insulating boards are attached to the cement wall surfaces through adhesion agents, and a flat board of the short right-angle section steel penetrates through the space between every two adjacent insulating boards; (5) flat boards of every two pieces of short right-angle section steel distributed longitudinally are connected with the two ends of the strip-shaped right-angle section steel respectively; (6) the insulating layer is formed after each outer board is connected with a flat board of the strip-shaped right-angle section steel corresponding to the corresponding outer board, and space is filled with the foam concrete. The construction method can overcome the defects in the prior art, the thickness of the insulating layer reaches more than eight centimeters, and the heat preservation effect, the heat insulating effect and other performance reach higher levels.

Description

technical field [0001] The invention relates to an external wall thermal insulation technology, and relates to a construction method for an external shear wall thermal insulation layer. Background technique [0002] External wall insulation is an important construction link in building construction. The construction quality of external wall insulation directly affects the living and use quality of buildings. Therefore, in order to improve the quality of external wall insulation, in recent years, technical personnel in the field have provided more A construction method for external wall insulation. The usual external wall insulation construction method is to connect the granular insulation layer, steel wire mesh, anti-crack mortar layer and paint layer in sequence. Although the construction of this insulation layer is simple, the deficiency is due to the corner The support strength cannot be solved, so the insulation layer is thin, it is difficult to achieve more than 8 cm, t...

[0002] External wall insulation is an important construction link in building construction. The construction quality of external wall insulation directly affects the living and use quality of buildings. Therefore, in order to improve the quality of external wall insulation, in recent years, technical personnel in the field have provided more A construction method for external wall insulation. The usual external wall insulation construction method is to connect the granular insulation layer, steel wire mesh, anti-crack mortar layer and paint layer in sequence. Although the construction of this insulation layer is simple, the deficiency is due to the corner The support strength cannot be solved, so the insulation layer is thin, it is difficult to achieve more than 8 cm, the insulation effect is poor, and the waterproof permeability is low. The foam method requires many steps in the construction process, and the operation technology requirements in high-altitude operations are relatively high, and the construction quality is difficult to guarantee. At the same time, the strength, impact resistance and thermal insulation performance of this insulation layer are difficult to meet the requirements of modern buildings. The service life of the insulation layer is low, and it is easy to fall off
