Problems solved by technology

[0003] In the actual application process of the project, due to comprehensive reasons such as plate deformation, surface material swelling (shrinkage), and surface material temperature deformation, the external wall is prone to cracking along the block joints and panel material joints, causing water seepage, resulting in heat preservation in some parts Cotton with high humidity or high water content, and multiple interior decoration damages (inside of exterior walls, ceiling)

Embodiment Construction

[0032] (1) Wall pretreatment:

[0033] ① Investigate the outer wall, mainly investigate the parts suspected of serious water ingress, cut the inner wall at these parts, and check the moisture content of the insulation cotton. When the vertical compression deformation of the insulation wool exceeds 3% due to the serious water content of the rock wool, or the compression of a single piece of insulation wool exceeds 3cm, or the insulation wool is damaged, it is considered serious. At this time, the insulation wool should be replaced, and the keel and connection rust should be observed at the same time. case, deal with it separately.

[0034] ②Temporarily seal the cracked gaps in the outer wall to prevent further water ingress during construction.

[0035] ③ Grind the protruding particles of the imitation stone coating so that the G / 1 keel can be adhered to. For the parts that should be leveled according to the design requirements, the coating should be leveled so that the alumin...

Abstract

The invention relates to an external wall system repair method and belongs to the technical field of building construction. The method comprises the steps that after an external wall is preprocessed, the positions of wall keels are verified and marked; isolating bars are arranged transversely along a wall body, and meanwhile, the wall body is coated with a waterproof breathable film; after aluminum alloy parts are mounted and fixed, G / 1 bars and XPS plates are paved from bottom to top, and then network cloth plastering is performed; and finally, vertical deformation joints are arranged in the horizontal direction. The external wall system repair method is applied to external wall repairing, and has the advantages of reliable anchorage, double-layer waterproofness and the like.

Description

technical field [0001] The invention relates to a method for repairing an exterior wall system, which belongs to the technical field of building construction. Background technique [0002] At present, the external wall of light steel composite fiberboard is widely used in steel frame structure buildings. The commonly used method in my country is: galvanized steel frame plate, 10 thick cement fiberboard nailed on the outside, 60 thick Hubang board nailed inside, and insulation cotton in the middle. The stone-like paint is applied on the outside, and the vertical keel spacing in the steel frame plate is generally ≤600mm. [0003] In the actual application process of the project, due to comprehensive reasons such as plate deformation, surface material swelling (shrinkage), and surface material temperature deformation, the external wall is prone to cracking along the block joints and panel material joints, causing water seepage, resulting in heat preservation in some parts The c...
