Thick plastered exterior wall outer heat-insulation system with double-layer gridding cloth compounded with foam cement boards

Abstract

The invention discloses a thick plastered exterior wall outer heat-insulation system with double-layer gridding cloth compounded with foam cement boards. The thick plastered exterior wall outer heat-insulation system comprises an interface layer, a leveling layer, an adhesion mortar layer, a heat-insulation layer with the foam cement boards, an anti-crack protective layer with the inlaid double-layer gridding cloth and a finishing layer. The interface layer, the leveling layer, the adhesion mortar layer, the heat-insulation layer with the foam cement boards, the anti-crack protective layer with the inlaid double-layer gridding cloth and the finishing layer are sequentially fixedly connected with one another from the inside to the outside on the basis of a base-layer wall, joint filling and leveling heat-insulation materials are embedded in gaps of the foam cement boards in the heat-insulation layer with the foam cement boards, and the anti-crack protective layer with the inlaid double-layer gridding cloth comprises first gridding cloth, anchoring parts, second gridding cloth and three layers of anti-crack mortar. The thick plastered exterior wall outer heat-insulation system has the advantages that common quality problems of plate marks, anchor bolt marks, cracks and the like of a thin plastered system can be solved, the anchoring parts are assuredly positioned on the outer side of the gridding cloth, performance indexes of the wind load resistance, water absorption, impact resistance and the like of the outer heat-insulation system are increased, and the safety of the system is improved.

Description

technical field [0001] The invention relates to the field of building thermal insulation materials, in particular to an external thermal insulation system of a double-layer grid cloth composite foamed cement board thick plastered external wall. Background technique [0002] Composite foamed cement board is one of the few undisputed A-grade fireproof and thermal insulation materials with complete certificates on the market. It has the advantages of high strength, light weight, thermal insulation, and service life synchronized with buildings, especially suitable for summer heat. Use in cold winter areas. [0003] However, due to the backward production equipment of the composite foamed cement board, especially the low precision of the cutting equipment, the size deviation of the foamed cement board is relatively large. Foam cement board thinly plastered external wall external insulation system is prone to common quality problems such as board marks, anchor bolt marks, and cra...
