Embodiment Construction

[0018] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0019] Such as figure 1 Shown, the exterior wall construction technique of described dry wall comprises the steps:

[0020] Base wall 1 cleaning: the pre-buried pipes (pieces) protruding from the outer wall of base wall 1 have been installed and the thickness of the insulation layer has been reserved; the holes in the scaffolding joints and the wall defects have been repaired; the walls should be clean , no oil stains and floating ash; loose and weathered parts should be removed; the flatness and verticality of the base wall 1 should meet the specification requirements, so as to avoid partial insufficient thickness of polyurethane spraying; before spraying polyurethane insulation layer 3, door and window frames, scaffolding and non-insulation should be done Part of the occlusion work.

[0021] Hanging vertical line: After the base treatment, in o...

Abstract

The invention relates to an exterior wall construction process of a dry wall and particularly relates to a construction process of an overall waterproof exterior wall heat insulation and energy conservation system. The construction process comprises the following steps: cleaning the exterior wall of a base wall; pasting fireproof isolation strips on the surface of the exterior wall; brushing polyurethane moisture-proof primer coat on the surface of the exterior wall; coating a polyurethane heat insulation material on the surface of the moisture-proof primer coat; coating and brushing an interface agent on the surface of the polyurethane heat insulation material; plastering polyphenyl granules on the surface of the interface agent; and slicking and plastering anti-crack mortar on the surfaces of the polyphenyl granules. The construction process is low in requirements on the base wall; the dry exterior wall does not need to be plastered and leveled and is directly constructed; the construction time is reduced; the constructed exterior wall is high in integrality and free of joints; cracking of the heat insulation layer can be effectively avoided; polyurethane foams intrinsically have waterproof effects; meanwhile, the exterior wall is integrally coated, so that the exterior wall has a good waterproof effect; the hidden trouble of leakage of the exterior wall can be effectively eliminated.

Description

technical field [0001] The invention relates to an exterior wall construction process of a dry wall, in particular to a construction process for an integral waterproof exterior wall heat preservation and energy-saving system of a dry wall. Background technique [0002] As an important part of the energy-saving division, the external wall insulation project is currently on the market using EPS and XPS boards for pasting. This kind of construction method is prone to quality problems such as water seepage of the outer wall, falling off of the insulation board, cracks, etc., and may easily lead to safety accidents in severe cases. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned defect that prior art exists, has proposed a kind of exterior wall construction technique of dry wall, and it can reach the characteristics of good waterproof effect, firm structure, short construction period. [0004] The present invention is rea...
