Problems solved by technology

[0011] First, the leakage and mildew spots on the FGRC and TCP facing walls are due to the long-term penetration and erosion of rainwater and the organic matter carried in the air penetrates into the shallow surface of the wall with the erosion of rainwater. A large number of other molds such as Penicillium and Aspergillus niger have been reproduced, which is harmful both in terms of aesthetics and environmental health. At the same time, mold spots appearing on building walls are also called building cancer, which is difficult to cure

Embodiment 1

[0046] A method for repairing building exterior walls and structure exterior walls, comprising the steps of:

[0047] (1) cleaning the surface of the exterior wall 1, removing stains and mold spots on the surface of the exterior wall 1, and then drying;

[0048] (2) Cut on both sides of the crack 2, cut out the groove 3, and cut the cutting mechanism along the sides of the crack 2 at about 10mm. When cutting, the angle between the cutting mechanism and the surface of the outer wall 1 is an acute angle , the cutting depth is 15-20mm, and the center of the crack 2 is cut once to facilitate the removal of the cutting block. Use a chisel to gently remove the cutting fast, keep the outer ends of the groove 3 from being damaged and intact, and then clean the crack 2. Groove 3, dry;

[0049] (3) Adopt high-pressure grouting method to fill the caulking glue in the crack 2, after the caulking glue is solidified, brush the waterproofing agent on the inner surface of the groove 3, and d...

Embodiment 2

[0068] The repair method for the cracked and permeable exterior wall of a domestic cultural tourism project includes the following steps:

[0069] (1) cleaning the surface of the exterior wall 1, removing stains and mold spots on the surface of the exterior wall 1, and then drying;

[0070] (2) Cut on both sides of the crack 2, cut out the groove 3, and cut the cutting mechanism along the sides of the crack 2 at about 10mm. When cutting, the angle between the cutting mechanism and the surface of the outer wall 1 is an acute angle , the cutting depth is 15-20mm, and the center of the crack 2 is cut once to facilitate the removal of the cutting block. Use a chisel to gently remove the cutting fast, keep the outer ends of the groove 3 from being damaged and intact, and then clean the crack 2. Groove 3, dry;

[0071] (3) Adopt high-pressure grouting method to fill the caulking glue in the crack 2, after the caulking glue is solidified, brush the waterproofing agent on the inner s...

Abstract

The invention provides a building exterior wall and structure exterior wall repairing method which comprises the following steps: (1) cleaning the exterior wall surface, removing stains and mildew spots on the exterior wall surface, and then carrying out drying in the air; (2) cutting a groove on two sides of a crack, cleaning the crack and the groove, and carrying out drying in the air; (3) fullyfilling the crack with a caulk compound, coating the inner surface of the groove with a waterproof agent after the caulk compound is solidified, and carrying out drying in the air; (4) filling the groove with a composite epoxy resin material and carrying out solidification; (5) brushing the exterior wall surface with a mildew inhibitor and carrying out drying in the air; and (6) carrying out coating with the waterproof agent on the mildew inhibitor, and carrying out coating with finishing paint after drying in the air. According to the building exterior wall and structure exterior wall repairing method provided by the invention, the crack can be cut into the groove of which the interior is large and the exterior is small; due to the characteristic that the exterior of the groove is largeand the interior of the groove is small, the separation of the newly-repaired part can be restricted; and the newly-repaired part can be protected against the falling-off phenomenon.

Description

technical field [0001] The invention belongs to the field of wall restoration, in particular to a method for repairing building exterior walls and structure exterior walls. Background technique [0002] With the rise of many themed playgrounds in China, the theme-style FGRC / TCP decorative walls in the venues are more abundant and render their core themes. However, after the erosion of rain and sunlight ultraviolet rays over time, the original colorful Cracks, skin peeling, powdering, and dark black or dark green mold and mildew spots gradually appeared on the FGRC and TCP decorative walls. Greatly affected its original appearance. The above-mentioned problems occurred on some walls of the film and television city, and with the penetration of rainwater, the internal steel structure has been affected, and a large amount of metal corrosion has appeared. If it is not repaired in time, there will be certain safety hazards. [0003] In many themed decorative FGRC / TCP facing wal...
