Detailed Description
The following description of the embodiments of the present application is provided by way of specific examples, and other advantages and effects of the present application will be readily apparent to those skilled in the art from the disclosure herein. The present application is capable of other and different embodiments and its several details are capable of modifications and/or changes in various respects, all without departing from the spirit of the present application.
The present application is described in further detail below with reference to fig. 1.
The embodiment of the application discloses a plugging construction process of a fully-inserted outer wall screw hole. Referring to fig. 1, the plugging construction process of the fully-inserted outer wall screw hole comprises the following steps:
the method comprises the steps of firstly, constructing the screw hole 6 into a horn shape before plugging, expanding the outer wall surface 12 of the screw hole 2 into a horn shape by using an electric drill with the diameter of 16mm, gradually reducing the inner diameter of the screw hole 6 with the depth of the horn mouth of 40mm, the diameter of the bottom of 16mm and the diameter of an outer opening of 60-80 mm from one side outside the wall body to one side inside the wall body, cleaning the inside of the screw hole 6 completely, and driving a small rubber plug 1 into one side of the wall body close to the outdoor water-facing surface to plug the screw hole 6 tightly.
Step two, from the outdoor one side of wall body to drive into the foamer in the screw hole 6 and the extrusion is closely knit, and the foamer uses the polyurethane foamer in this embodiment, forms filling layer 2, in order to make filling layer 2 more closely knit, drives into the polyurethane foamer and fills up whole screw hole 6, makes things convenient for follow-up construction to press filling layer 2 more closely knit.
Meanwhile, in order to stabilize the filling layer 2 in the screw hole 6 and reduce the possibility that the filling layer 2 is loosened from the screw hole, at least one circular grid plate 61 is fixed in the screw hole 6, the grid plate 61 is made of plastic in the embodiment, one grid plate 61 is arranged, the number of the grid plates 61 can be determined according to the length of the screw hole 6 in other embodiments, the grid plate 61 has certain deformation capacity, and the grid plate 61 divides the screw hole 6 into a plurality of parts. In order to make the grid plate 61 more stable in the screw hole 6, an annular clamping groove 62 is formed on the length side wall of the middle position in the screw hole 6, and the clamping groove 62 is arranged around the inner wall of the screw hole 6.
When filling polyurethane foaming agent, earlier with the partial filling in screw hole 6, fill to the position of draw-in groove 61, go into draw-in groove 62 with grid plate 61 card, continue to fill polyurethane foaming agent, fill the net on the grid plate 61 completely, grid plate 61 can increase the adhesion of polyurethane foaming agent and screw hole 6 inner wall, can increase the steadiness of filling layer 2, filling layer 2 that is more firm in screw hole 6, fill polyurethane foaming agent until filling to the position of the entrance to a cave of screw hole 6, fill up screw hole 6.
And step three, a large rubber plug 3 is driven into the screw hole 6 from one side of the wall body outside the wall body to tightly plug the screw hole 6, and when the large rubber plug 3 enters the screw hole 6, the polyurethane foaming agent is extruded into the screw hole 6, so that the polyurethane foaming agent is more tightly filled, and the polyurethane foaming agent is tightly pressed on the small rubber plug 1.
And step four, plugging the screw holes 6 at the indoor side and the outdoor side of the wall body to form a plugging layer 4, wherein the plugging layer 4 in the embodiment uses micro-expansion waterproof mortar, and the holes at the two sides of the screw holes 6 are plugged. Meanwhile, in order to increase the stability between the micro-expansion waterproof mortar and the inner wall of the screw hole 6, the mesh cloth is arranged at the positions of the holes at the two sides of the screw hole 6, in order to fix the mesh cloth in the screw hole 6, the mesh cloth is stuffed in the screw hole 6 when the small rubber plug 1 and the large rubber plug 3 are driven in, meanwhile, the rest mesh cloth is paved on the inner walls of the holes at the two sides of the screw hole 6, the micro-expansion waterproof mortar is poured into the screw hole 6, the expansion waterproof mortar is paved on the Wangcao, the expansion waterproof mortar is contacted with the mesh cloth, the mesh cloth is fixed in the screw hole 6 through the small rubber plug 1 and the large rubber plug 3, the stability of the plugging layer 4 in the screw hole 6 can be increased, and the possibility that the plugging layer 4 falls off is reduced.
Step five, brush waterproof layer 5 on the shutoff layer 4 of the outdoor one side of the upstream face of wall body, the waterproof layer 5 uses JS polymer waterproof coating in this embodiment, waterproof layer 5 is the positive direction that length and width are 100mm, after thickness is 1.5mm, waterproof layer 5 can be with the gap shutoff between shutoff layer 4 and the 6 inner walls of screw hole, can reduce water and flow into in screw hole 6 from the gap, cause the possibility of damage to the wall body, can play waterproof effect well.
Finally, the above embodiments are only used for illustrating the technical solutions of the present application and not for limiting, although the present application is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present application without departing from the spirit and scope of the technical solutions of the present application, and all the technical solutions of the present application should be covered by the claims of the present application.
