Embodiment Construction

[0027] The present invention is described in detail below in conjunction with embodiment.

[0028] The construction method of extruded board exterior wall external thermal insulation described in this embodiment is carried out according to the following steps:

[0029] a. Wall base treatment.

[0030] Thoroughly remove floating ash, oil stains, release agents, hollows and weathered materials on the surface of the base wall that affect the bonding strength. The base wall should be cleaned as much as possible to facilitate the pasting of the extruded board.

[0031] b. Paste the extruded board.

[0032] In order to increase the adhesion between the extruded board and the base layer and the surface layer, firstly brush the interface agent on both sides of the extruded board. The bonding method adopts the spot dipping method, that is, apply 80-100MM wide and 10MM thick adhesive mortar on the four corners of the inner surface of the extruded board, and leave a 50MM exhaust chann...

Abstract

The invention relates to a building external-wall heat insulation construction method, in particular to an extruded-sheet external-wall external heat insulation construction method comprising the following steps: treating the basal layer of the wall surface, sticking extruded sheets, fixing the extruded sheets, installing gridding cloth, coating polymer mortar on the finishing layer, installing U-shaped fasteners and constructing the decorative layer. The construction of the decorative layer comprises the following steps: knife-coating soft water-resistant putty, brushing special alkali-resistant primer, spray-coating stone paint and spray-coating coating varnish. The method can ensure the flatness of the heat insulation layer, increase the thickness of the mortar layer especially by usingthe U-shaped fasteners and control the error within 5 mm, but the traditional construction process can not easily control the error. The surface layer does not easily fall off, and the thickness of the anti-cracking mortar needs to be controlled within 2-3 mm according to the specification requirement, otherwise, the surface layer can easily fall off. The traditional construction can not meet theflatness requirement for the same thickness; but after the method uses the U-shaped fasteners, the thickness of the anti-cracking mortar can be properly adjusted so as to meet the flatness requirement and ensure that the surface layer does not easily fall off.

Description

Technical field: [0001] The invention relates to a construction method for thermal insulation of an exterior wall of a building, in particular to a construction method for thermal insulation of an exterior wall of an extruded board. Background technique: [0002] The traditional thermal insulation construction method of extruded board exterior wall has many unsatisfactory aspects, and often fails to meet the specification requirements. In the construction process, there are many problems. After the construction is completed, the flatness does not meet the 4mm error required by the specification. It has a serious impact on the overall appearance of the building, thereby reducing the quality of the project. Invention content: [0003] The purpose of the present invention is to provide a thermal insulation construction method for extruded board exterior wall aiming at the deficiencies of the traditional extruded board exterior wall insulation construction method, which can e...
