Embodiment

[0015] Embodiment, construction method step of the present invention:

[0016] a. During construction, firstly, thoroughly remove floating ash, oil stains, release agents, hollows and weathered substances on the surface of the base wall that affect the construction of the wall. When the protrusions on the wall surface are greater than or equal to 10mm, they should be removed;

[0017] b. Brush the interface mortar on the base wall;

[0018] c. Carry out the insulation layer construction, the insulation thickness should meet the design thickness requirements, and carry out the leveling treatment of the insulation layer;

[0019] d. Apply anti-cracking gypsum 3mm-10mm thick and perform leveling treatment;

[0020] e. Paste the non-woven fabric with an adhesive on the anti-crack gypsum surface layer, and use butt joints at the seams of the non-woven fabric, and no wrinkles are allowed when the non-woven fabric is pasted;

[0021] f. Flexible putty for scraping interior walls; ...

Abstract

The anti-cracking inner thermal insulation wall includes base layer, interface layer, thermal insulating layer, leveling layer, anti-cracking protecting layer, inner putty layer and facing decorating layer. Its anti-cracking protecting layer consists of successively adhered leveling gypsum layer, adhering layer and non-woven fabric layer. The construction process includes the steps of: wall base treatment via painting interface mortar; constructing thermal insulating layer and leveling layer; painting 3-10 mm thick anti-cracking gypsum and leveling before adhering non-woven fabric; scraping flexible inner wall putty; and constructing the facing decorating layer. The present invention has relatively low anti-cracking cost and high anti-cracking effect.

Description

technical field [0001] The invention relates to a thermal insulation wall body and a construction method thereof. Background technique [0002] In the existing internal thermal insulation wall and construction methods, the anti-crack protection treatment is generally carried out by using polymer anti-crack mortar composite glass fiber mesh cloth on the thermal insulation layer. In this method, since the thickness of the glass fiber mesh cloth is relatively large, the anti-cracking layer is relatively thick, so the amount of polymer anti-cracking mortar consumed is also relatively large, so the cost is relatively high. When the crack layer is too thick, the anti-crack protection effect will be weakened, so the wall is easy to crack. Contents of the invention [0003] The invention provides a crack-resistant inner thermal insulation wall and a construction method, which solve the technical problems that the thermal insulation and crack-resistant protective layer is easy to ...
