Plugging method for fabricated outer wall hole

Abstract

The invention relates to the technical field of building construction, and particularly relates to a plugging method for a fabricated outer wall hole. The plugging method comprises the following steps that 1, a containing cavity is formed above the hole of a wall body; 2, a first extruded sheet and a second extruded sheet are sequentially arranged in holes of a heat preservation plate and an outer sheet plate on the outer side of the wall body; 3, a first formwork is arranged on the outer side of the outer sheet plate to fix the second extruded sheet, and a second formwork is arranged on the inner side of the wall body to plug the hole of the wall body; 4, concrete is poured into the hole of the wall body; 5, the second formwork, the first formwork, a screw and the second extruded sheet are removed; 6, the hole of the outer sheet plate is plugged with cement mortar; and 7, the outer sheet plate is coated with waterproof paint. According to the plugging method, the concrete is poured into the hole of the wall body, the hole of the outer sheet plate is plugged with the cement mortar, a plugging structure with a heat preservation layer is formed by cooperating with the first extruded sheet in the hole of the heat preservation plate, a cold bridge is prevented from occurring at the hole, and the heat preservation performance and the waterproof quality are improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for sealing an opening of an assembled outer wall. Background technique [0002] In the construction process of high-rise shear wall structures, the erection of scaffolding generally chooses the cantilever method. The wall structure of force wall, insulation board and outer leaf board is integrated. Therefore, there are certain difficulties in how to seal and repair the external insulation structure for the holes left on the assembled outer wall. The existing method is to directly seal the entire hole with fine stone concrete, but this method will cause the outer wall of the hole to have no insulation or leave bolt holes in the outer wall, which will easily form a cold bridge at this part, and the waterproof effect will be significantly reduced. Therefore, it is necessary to provide a sealing method for the openings in the prefabricated external wall struc...
