Glass fiber mesh reinforcement, external thermal insulation and anti-cracking structure of wall and its construction method

Abstract

The invention relates to a glass fiber net reinforcement part, an exterior wall heat-preservation anti-cracking structure and a construction method of the exterior wall heat-preservation anti-cracking structure. The glass fiber net reinforcement part is of an integral sheet structure formed by two fixing sheets with the same shape and a connecting bridge connected between the two fixing sheets, and a threaded hole penetrating through a screw is formed at the center position of the fixing sheet. In addition, the glass fiber net reinforcement part is designed to be used for reinforcing the connecting strength of an anti-cracking mortar layer and a heat preservation layer, the glass fiber net reinforcement part has a simple structure, has low cost, can be constructed conveniently, and has a good fixing effect, can compensate the strength loss when the binding power between the anti-cracking mortar layer and the heat preservation layer is low, and can ensure the bonding quality and the construction reliability of the follow-up surface layer, the construction operation is simple, the construction difficulty is not increased, the original construction quality and the construction efficiency are not influenced, the using amount of the anti-cracking mortar can be used to a certain extent, the cost is reduced and the glass fiber net reinforcement part can be widely applied to exterior wall construction.

Description

technical field [0001] The invention relates to a reinforcement device, an external thermal insulation and crack resistance structure of a wall and a construction method thereof. Background technique [0002] At present, the construction industry generally adopts block materials such as EPS, XPS, phenolic resin, polyurethane or rock wool composite boards for thermal insulation of building exterior walls, cornices, parapets, etc., and then paints exterior walls. When these block materials are used, in order to ensure the decoration effect of the outer decorative layer, the anti-cracking layer is generally constructed by adding anti-cracking mortar and alkali-resistant glass fiber mesh. Alkali-resistant glass fiber mesh is alkali-resistant glass fiber grid cloth. The existing anti-cracking mortar construction process for external thermal insulation is "cleaning the insulation layer - plastering the anti-cracking mortar on the bottom layer - pressing in the alkali-resistant gl...
