Abstract
A kind of outer shear wall bolt hole plugging structure, comprise waterproofing course, sealant and packed layer, described sealant is placed in both sides inside and outside body of wall, coincides outside sealant with body of wall, and sealant open side is tubaeform, and its sealant thickness is the inside 40mm of body of wall; Described packed layer is placed between sealant, 40mm inside its thickness body of wall; Described waterproofing course is placed in wall outer side sealant, and its scope is the circle of the radius 75mm centered by bolt hole.Outer shear wall bolt hole plugging structure of the present utility model, easy construction, effectively can control shutoff quality and the seepage problem at outer shear wall bolt hole place, reduces the work for the treatment of of later stage exterior wall, has higher application value.
Description
Technical field
The utility model relates to a kind of outer shear wall bolt hole plugging structure, belongs to technical field of building construction.
Background technology
At present, highrise building particularly high residential building structural system mostly is Frame-Shear Wall system, and its exterior wall scaffold generally adopts overhanging type or overall climbing type scaffold, must leave larger hole when structure construction.In recent years, the measure of process outer shear wall bolt hole gets more and more, wherein, with the shutoff of swelling polymer waterproofing mortar, fill in real hole and compacting troweling is a kind of by the technical measures generally applied, this technical measures easy construction, but bolt hole place shutoff quality and waterproof requirement can not be guaranteed, easily cause outer shear wall to seep water, add the work of body of wall post-processed.
Summary of the invention
For the deficiency that prior art exists, technical problem to be solved in the utility model is, provides a kind of outer shear wall bolt hole plugging structure, easy construction, effectively can control shutoff quality and the seepage problem at outer shear wall bolt hole place, reduce the work for the treatment of of later stage exterior wall.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of outer shear wall bolt hole plugging structure, comprise waterproofing course, sealant and packed layer, described sealant is placed in both sides inside and outside body of wall, coincide with body of wall outside sealant, sealant open side is tubaeform, and its sealant thickness is the inside 40mm of body of wall; Described packed layer is placed between sealant, 40mm inside its thickness body of wall; Described waterproofing course is placed in wall outer side sealant, and its scope is the circle of the radius 75mm centered by bolt hole.
Further, described waterproofing course is by 3 layers of polyurethane water-proof paint.
Further, described sealant is expansive cement mortar.
Further, described packed layer is polyurethane foaming layer.
Further, the described tubaeform degree of depth is about 20mm, and collar extension diameter is about 30mm.
Outer shear wall bolt hole plugging structure of the present utility model, easy construction, effectively can control shutoff quality and the seepage problem at outer shear wall bolt hole place, reduces the work for the treatment of of later stage exterior wall, has higher application value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further details.
As shown in Figure 1, a kind of outer shear wall bolt hole plugging structure, comprises waterproofing course 1, sealant 2 and packed layer 3, described sealant 2 is placed in both sides inside and outside body of wall 4, coincide with body of wall 4 outside sealant 2, sealant 2 open side is tubaeform, and its sealant 2 thickness is body of wall 4 inwardly 40mm; Described packed layer 3 is placed between sealant 2,40mm inside its thickness body of wall 4; Described waterproofing course 1 is placed in body of wall 4 outer side seal layer, and its scope is the circle of the radius 75mm centered by bolt hole.Further, described waterproofing course 1 is by 3 layers of polyurethane water-proof paint.Further, described sealant 2 is expansive cement mortar.Further, described packed layer 3 is polyurethane foaming layer.Further, the described tubaeform degree of depth is about 20mm, and collar extension diameter is about 30mm.
Specific construction process is:
1, removed by the pvc pipe exposing metope with perching knife, the remaining mortar of eyelet periphery is cleaned out, and sweeps only with hairbrush.
2, with the electric drill of diameter 16mm, eyelet is expanded into toroidal, the degree of depth is about 20mm, and collar extension diameter is about 30mm.
3, carry the previous day use water to carry out cleaning moistening.
4, outside exterior wall, 40mm in shutoff hand-hole is carried out with expansive cement mortar, with round steel tamping and wall floating.
5, polyurethane foam is carried out, to inner side of outer wall metope 40mm place from side within the walls after expansive cement mortar reaches some strength every other day.
6, with perching knife, residual blowing agent is cleaned out.
7, side expansive cement mortar is in fact stifled by bolt hole within the walls, with round steel tamping and wall floating.
8, bolt hole is with after cement mortar shutoff, maintenance about 3 days.
9, outside exterior wall after mortar drying, with polyurethane waterproofing paint brush at bolt hole place, for anti-leak-stopping brush and brushing pass inadequate, divide the polyurethane water-proof paint brushing of 3 kinds of different colours, first pass is white, is for second time red, 3rd time is black, and shape is the circle that diameter is about 150mm.
As mentioned above, we are illustrated according to aim of the present utility model completely, but the utility model is not limited to above-described embodiment and implementation method.Different changes and enforcement is carried out in the scope that the practitioner of correlative technology field can permit at technological thought of the present utility model.
