Embodiment 1

[0062] Such as Figure 4 As shown, when there is an original PVC pipe 3 in the hole of the wall, the method for plugging the hole of the wall includes the following steps: the first step is to clean up the residue in the original PVC pipe 3 with the air gun of a small air compressor; The original PVC pipe 3 exposed on the wall, in order to remove the original PVC pipe 3 once with a shovel to avoid secondary cleaning, it is necessary to mark the joint between the original PVC pipe 3 and the wall with a shovel. Flat with the wall to reduce the occurrence of deviation; the third step is to use a brush to clean the residue around the wall hole 2; the fourth step is to hammer the waterproof sealing plug 7 from the outer wall into the wall hole 2 with a hammer In the original PVC pipe 3; the fifth step, fill the flame-retardant polyurethane foaming agent 8 into the original PVC pipe 3 in the hole 2 of the wall; in the sixth step, use a spatula to flush with the wall 1 to remove resi...

Embodiment 2

[0064] Such as Figure 2a and Figure 5 As shown, when there is no PVC pipe in the hole in the wall, the method for sealing the hole in the wall includes the following steps: the first step is to clean the residue in the hole 2 with the air gun of a small air compressor; the second step is to clean the wall with a brush The residue around the body hole 2; the third step is to hammer the waterproof sealing plug 7 from the outer wall into the wall hole 2 with a hammer; the fourth step is to fill the flame-retardant polyurethane foaming agent 8 into the wall hole 2; The fifth step is to remove the residual foaming agent flush with the wall 1 with a spatula; the sixth step is to use plastering mortar to smooth the inner wall.

Embodiment 3

[0066] Such as Figure 2b and Figure 6 As shown, when there is no PVC pipe in the hole in the wall, the method for sealing the hole in the wall includes the following steps: the first step is to clean the residue in the hole 2 with the air gun of a small air compressor; the second step is to clean the wall with a brush The residue around the body hole 2; the third step is to hammer the waterproof sealing plug 7 from the outer wall into the wall hole 2 with a hammer; the fourth step is to fill the flame-retardant polyurethane foaming agent 8 into the wall hole 2; The fifth step is to hammer the waterproof sealing plug 7 from the inner wall into the wall hole 2 with a hammer; the sixth step is to remove the residual foaming agent with a spatula flush with the wall 1; the seventh step is to use plastering glue Slurry is used to smooth the inner wall surface.

Abstract

The invention discloses a sealing structure and method for a wall hole. The sealing structure comprises a wall and a hole formed in the wall, and comprises a waterproof sealing plug, and the waterproof sealing plug is plugged into the wall hole from the outer side and / or the inner side of the wall. The waterproof sealing plug is in a circular truncated cone shape, the diameter of the top face of the waterproof sealing plug is smaller than the diameter of the wall hole, and the diameter of the bottom face of the waterproof sealing plug is larger than the diameter of the wall hole. When the sealing structure is installed, the top face of the waterproof sealing plug is inserted into the wall hole firstly, and is rapidly embedded into the wall through hammering, the technology is simple, and the efficiency is high. The waterproof sealing plug is formed by waterproof and elastic vinyl plastic, and has the good waterproof performance. According to the sealing structure and method for the wall hole, the technology is simple, the efficiency is high, the construction period is short, time of work high above the ground of constructors is shortened, hidden danger is reduced, the sealing effect is good, and leakage of an outer wall is effectively prevented.

Description

technical field [0001] The invention relates to the field of building wall construction, in particular to a wall hole sealing structure and method. Background technique [0002] Wooden formwork construction technology is widely used in shear walls of buildings to ensure smooth concrete surfaces and small dimensional deviations, while reducing the amount of secondary plastering. During the process of strengthening the wooden formwork, holes for through-wall bolts will be left in the shear wall. Currently, if figure 1 As shown, the plugging of the through-wall bolt hole includes the following steps: first, use an electric drill, hammer or chisel to break the original PVC pipe out; then, clean and moisten the hole; then, use a trowel to remove the mortar 4 from the through-wall Fill in both ends of the bolt holes, and then smooth them; finally, apply double-layer polyurethane waterproof coating on the smoothed part of the outer wall, the first polyurethane waterproof coating ...
