Insulated construction method of wall body

Abstract

The invention relates to the technical field of concrete building wall bodies, in particular to an insulated construction method of a wall body. The insulated construction method is characterized by comprising the following steps: 1), treating a base course wall; 2) making a wall surface marking line; 3) point-sticking mortar on an insulated board; 4), adhering the wall surface with the insulatedboard; 5), treating holes of doors and windows and toes of walls; 6) mounting fixed pieces; 7), smearing anti-cracking and waterproof bottom-layer mortar; 8), paving grid cloth; and 9) smearing an anti-cracking and waterproof surface layer. Compared with the prior art, the insulated construction method disclosed by the invention has the following advantages that based on an existing construction method, the fireproofing grade of an insulated layer can be improved by adopting the polystyrene vitreous flame-retardant insulated board, and additionally, putting emphasis on places, on which the insulated layers are easily stripped and dropped, of exposed corners of an outer wall body and four corners of windows, a compound reinforcing method of steel wires and reinforced anchor points is adopted, so that the connection strength of the insulated layers and the wall body is improved, the difficulties of non-uniformity of adhesive force of the insulated layers of the outer walls of high-rise buildings and poor fireproof performance are solved, and a concrete building construction goal with higher quality requirement can be achieved.

Description

technical field [0001] The invention relates to the technical field of thermal insulation of concrete building walls, in particular to a wall thermal insulation construction method with high fire resistance and excellent adhesion performance. Background technique [0002] External wall insulation is composed of polymer mortar, glass fiber mesh cloth, flame-retardant molded polystyrene foam board (EPS) or extruded board (XPS) and other materials, and is bonded on site. The construction process is carried out with polystyrene board as insulation material, polymer bonding mortar as bonding material, polymer plastering mortar as plastering layer, alkali-resistant glass fiber plastic-coated mesh cloth as reinforcement material and fastening nails. Construction and acceptance of external thermal insulation systems for anchored industrial and civil buildings. [0003] Construction requirements for external thermal insulation of exterior walls include: 1) Basic cleaning. Clean up ...

AI Technical Summary

Problems solved by technology

[0005] For high-rise buildings, affected by the windy weather at high altitudes, the requirements for the adhesion strength of the external wall insulation are higher. At the same time, high-rise fire protection is also a difficult point, and higher construction requirements need to be put forward. There are no detailed reports in the relevant literature.
