Insulation external wall repair technology

Abstract

The invention relates to the technical field of external wall repair, in particular to an insulation external wall repair technology. According to the insulation external wall repair technology, whena small amount of superficial shallow cracks appear in a finish coat, a reinforcing agent is injected into the cracks, the strength of the finish coat around the cracks is enhanced, and then adhesivemortar is injected into the cracks to repair the cracks; when a large amount of craquelure appears in a facing, the finish coat is remade, anti-cracking fibers are added to a finish coat material, andthe anti-cracking ability of the finish coat is improved; and when cracks appear in an insulation layer, the cracks are filled with fitting pieces after crack expanding, and the sufficient elastic space is provided for thermal expansion or contraction of the insulation layer. According to the insulation external wall repair technology, the repair way is convenient, the repair cost is low, and after repair, the service life of an insulation wall can be obviously prolonged.

Description

technical field [0001] The invention relates to the technical field of exterior wall repair, in particular to a thermal insulation exterior wall repair process. Background technique [0002] Since the 1990s, my country has begun to promote the application of foam plastic insulation boards and thin plastered external wall external insulation systems. The earlier multi-storey buildings have been used for more than 20 years. With the gradual increase of the service life, most of the early put into use Cracking, peeling, and cracking of the insulation layer have already appeared on the thermal insulation exterior wall, and complaints caused by this, as well as accidents such as personal injury and death, and damaged vehicles are common. The introduction of the Ministry of Housing and Urban-Rural Development's "Repair Standards for Building Exterior Wall Thermal Insulation System" indicates that the country has attached great importance to the repair of external wall thermal insul...

Problems solved by technology

The introduction of the Ministry of Housing and Urban-Rural Development's "Repair Standards for Building Exterior Wall External Thermal Insulation System" indicates that the country has attached great importance to the repair of external wall thermal insulation. Centuries of repairs and green houses will enter the "new normal". Wall repairs generally use adhesives to mix base materials and then fill and repair. The repaired part cannot be well bonded to the original wall surface, and the repaired wall surface will crack again on the basis of the original cracks in a short period of time. Repeated repairs higher cost
