Description
Technical field
The utility model is related to technical field of building construction, and in particular to a kind of closure knot of exterior wall Screw arbor with nut at both-ends hole
Structure.
Background technology
At present, can all be run into construction site need to block the problem of screw hole, present Normal practice when metope screw rod is removed
It is the PVC sleeve pipes for only cutting protrusion metope, is directly blocked at twice with cement mortar.The mode of existing closure screw rod eye is not
Construction quality hidden danger is only existed, seepage easily occurs in metope, later period maintenance is difficult, the problems such as maintenance cost is high, so existing
Closure screw rod eye mode it is still not perfect enough.
Utility model content
The purpose of this utility model is to provide a kind of plugging structure of exterior wall Screw arbor with nut at both-ends hole, to solve existing envelope
Easily there is seepage in the construction quality hidden danger that the mode of stifled screw rod eye is present, metope, and later period maintenance is difficult, and maintenance cost is high etc. asks
Topic.
What the utility model was realized in：
A kind of plugging structure of exterior wall Screw arbor with nut at both-ends hole, including exterior wall, are respectively equipped with inner wall surface inside and outside exterior wall
And wall face, the screw hole of insertion is provided with exterior wall, foaming agent is filled with the center aperture section of screw hole, it is outer in screw hole
The hole section of metope is filled with mixed with expansion filled with the waterproof cement mortar mixed with swelling agent in the hole section of the inner metope of screw hole
The cement mortar of agent.
Further, wall face one end filling is 50mm, interior wall mixed with the hole segment length of the waterproof cement mortar of swelling agent
The hole segment length that the cement mortar mixed with swelling agent is filled in face one end is 40mm.
Further, the waterproof cement mortar mixed with swelling agent is provided with wall face and is higher by wall face 5mm's
The ash cake of 50mm × 50mm.
Of the present utility model easy to operate, simple structure, practicality, reliability are high, durable in use, compared with prior art,
Quality is good, good water-proof effect to have the advantages that closure.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Mark in accompanying drawing for：1- screw holes, 2- waterproof cement mortars, 3- cement mortar, 4- foaming agents, 5- exterior walls, 6-
Wall face, 7- inner wall surfaces, 8- ash cakes.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in figure 1, the utility model is one end of 1 hole wall face of screw hole 6 on exterior wall 5 filling mixed with swelling agent
Waterproof cement mortar 2, the one end of inner wall surface 7 elder generation filling-foam agent 4, then blocked with the cement mortar 3 mixed with swelling agent.Wall face
The filling of 6 one end enters screw hole 150mm mixed with the waterproof cement mortar 2 of swelling agent, and the water mixed with swelling agent is filled in the one end of inner wall surface 7
Cement mortar 3 enters screw hole 140mm.
The waterproof cement mortar 2 mixed with swelling agent is filled in the one end of wall face 6, and make be higher by the 50mm of wall face 65mm ×
The ash cake 8 of 50mm.
The utility model is implemented：
During work, the PVC sleeve pipes that will expose metope with perching knife first are cleaned out, the remnants mortar cleanings of eyelet periphery, are used
Wire brush is swept only, is cleaned out plastic bushing in screw hole 1 using the electric drill of diameter 16.Carry the previous day be rinsed with water it is wet
Profit.With 1 of the UEA micro-expanding agents mixed with 10%:2 waterproof cement mortars 2 from the outside of wall face 6 block in screw hole 1
50mm, is consolidated with the round steel of Φ 10, and metope makes the ash cake 8 of 5mm thickness 50mmX50mm.The UEA micro-expanding agents mixed with 10% are treated every other day
1:2 waterproof cement mortars 2 to reach and foam sebific duct is goed deep into the bottom of screw hole 1 from inner wall surface 7 after some strength carry out foaming agent 4
Perfusion, perfusion depth is to apart from inner wall surface 740mm.Residual blowing agent 4 is cleaned out with perching knife.It is micro- swollen with the UEA mixed with 10%
The 1 of swollen dose:2 cement mortar 3 are stifled real by remaining 40mm screw holes 1, consolidated with the round steel of Φ 10 floating with inner wall surface 7.Treat screw hole
It has been blocked that, after waterproof mortar hardening, done water pouring test, the water pouring test time has been no less than 2 hours.Treat closure site it is fully hardened and
After ne-leakage, next step construction can be carried out.
It is only above the concrete application example of utility model, the utility model also has other implementation methods, all uses
The technical scheme that equivalent or equivalent transformation are formed, all falls within the protection domain required by the utility model.
