Construction method of high-strength short fiber composite building outer wall heat preservation layer

Abstract

The invention discloses a construction method of a high-strength short fiber composite building outer wall heat preservation layer. The construction method comprises the following specific steps that S1, the surface of an outer wall body is pretreated, specifically, floating sand and bulges on the surface of the outer wall body are cleaned, a vertical datum line is hung, and cement mortar is smeared on the sunken part of the wall surface for leveling; S2, threaded expansion bolts are mounted, specifically, mounting holes are drilled in the surface of the outer wall body through a handheld drill, the threaded expansion bolts are inserted into the mounting holes, and the threaded ends of the threaded expansion bolts are exposed out of the outer wall body; and S3, heat preservation plates are mounted, specifically, the heat preservation plates are hung on the threaded expansion bolts. According to the construction method, the heat preservation plates are hung on the surface of the outer wall body in advance, then the flatness of the heat preservation plates is adjusted, then adhesive cement is injected into gaps between the heat preservation plates and the outer wall body for bonding and fixing, the heat preservation plates do not need to be smeared with adhesives one by one, the plate width of the heat preservation plates can be properly increased, the coverage area of each mounted heat preservation plate is large, and the construction speed is greatly increased.

Description

technical field [0001] The invention relates to the technical field of resources and environment, in particular to a construction method of a high-strength short fiber composite type building exterior wall insulation layer. Background technique [0002] With the continuous improvement of the country's requirements for energy conservation and environmental protection, the insulation technology of building envelopes is also becoming more and more mature, especially the external wall insulation technology has been further developed, and has become an important building energy-saving technology in my country. Wall thermal insulation technology is mainly divided into external wall thermal insulation, external wall sandwich insulation and external wall thermal insulation. It is beneficial to improve the indoor environment, facilitate the renovation of old houses, and facilitate the enrichment of exterior facades. [0003] In the construction process of the existing external thermal...

Problems solved by technology

[0003] In the construction process of the existing external thermal insulation technology for external walls, when the thermal insulation boards are pasted on the external wall, the narrow thermal insulation boards are spliced ​​together, resulting in many joints, and improper handling is likely to cause cracks, and most of the joints need to be sealed one by one processing, affects the construction speed, and the construction period is long. The wide-width insulation board can reduce the number of splicing, but it is troublesome to apply the adhesive, and it is not easy to install on the wall. Construction method of thermal insulation layer of exterior wall of large-scale building
