Abstract

The invention relates to building construction, in particular to a method of plugging holes in a prefabricated outer wall of a fabricated concrete building. The method comprises the following steps that firstly, outdoor construction is conducted, specifically, the holes are cleared and the plugging construction hole depth is determined, polyethylene plates are prepared and serve as liners to be arranged in the holes, masking tapes are pasted on the peripheries of the holes, first coat liquid is brushed in the holes, the holes are filled with sealant, and the pasted masking tapes are torn down;and construction is transferred from the outdoor space to the indoor space, specifically, a foaming agent is injected into the holes, and hole openings facing the indoor space are filled with waterproof mortar. Compared with traditional hole plugging, according to the method of plugging the holes in the prefabricated outer wall of the fabricated concrete building, the problem that micro cracks are prone to being generated on the peripheries of the holes is solved, by arranging lining plates, the quantity of the filled sealant is set simply, practically and conveniently, the sealant is set, thus the obtained structure is better in waterproof performance, and the service life is longer.

Description

technical field [0001] The patent of the invention relates to building construction, in particular to a method for sealing holes in prefabricated exterior walls of prefabricated concrete buildings. Background technique [0002] At present, my country's prefabricated concrete buildings are in a stage of rapid development, but the relevant supporting standards and specifications still need to be continuously improved. Generally speaking, in order to meet the construction measures, prefabricated external walls will reserve some holes for installing pull screws and external hangers. Because the external surface of the prefabricated external wall often has no waterproof mortar plastering layer, and the internal surface generally has no plastering At this time, few construction units and design institutes have paid enough attention to the sealing of these reserved holes, so some construction units still use traditional sealing methods in order to save costs (see figure 1 ): The i...
