External wall insulation layer nondestructive repair method and external wall insulation structure

Abstract

The invention provides an external wall insulation layer nondestructive repair method. The external wall insulation layer nondestructive repair method comprises the following steps: (S1) original insulation layers to be repaired are pressed, and are provided with multiple transverse grooves; and then, the original insulation layers on each rows are returned and reinforced; (S2) primary plasteringglue is fully coated on the outer surfaces of one row of the original insulation layers; (S3) first transverse grid cloth is uniformly pressed into the primary plastering glue to form turning parts; (S4) new insulation plates are embedded in bottom grooves; the plastering glue is fully coated on the outer surfaces of the new insulation plates; and second transverse gird cloth is uniformly pressedinto the plastering glue to form joint parts; (S5) the steps (S2-S4) are repeated to embed the new insulation plates into the grooves from bottom to top; and (S6) secondary plastering glue is fully coated on the outer sides of all the transverse grid cloth; and the grid cloth is longitudinally bonded. The invention further provides an external wall insulation structure. The external wall insulation layer nondestructive repair method has the beneficial effects of capability of solving such problems as hollows, cracks or fall in the insulation layers and capability of preventing garbage and pollution generated during repair.

Description

technical field [0001] The invention relates to the technical field of building maintenance, in particular to a non-destructive repair method for an exterior wall insulation layer and an exterior wall insulation structure. Background technique [0002] With the rapid development of my country's urban and rural construction industry, the installation of external insulation systems on the exterior walls of high-rise and super high-rise buildings has become an important energy-saving technical measure for industrial and civil buildings. High, involving a wide range of areas, the construction is difficult, and its quality is difficult to control. Therefore, in recent years, various provinces and cities in my country have experienced water seepage and large-scale shedding of the external wall insulation layer to varying degrees. [0003] In the construction process of the existing repair and refurbishment of the external wall insulation system, it is generally used to eradicate h...
