Abstract
The invention discloses a concrete outer wall screw rod hole sealing and blocking structure, which comprises a concrete outer wall and a screw rod hole, wherein the screw rod hole penetrates through the cross section of the concrete outer wall; injection holes are formed in the inner side and the outer side of the screw rod hole; the screw rod hole is filled with foaming agents; waterproof mortar is injected into the injection holes of the screw holes formed at the two sides of the foaming agents and is used for sealing and blocking; three polyurethane waterproof paint layers sequentially coat the outer side surface of the concrete outer wall; and then, a cement mortar protection layer coats the outside of the three polyurethane paint layers for integrally sealing and blocking the screw rod hole. The invention also discloses a concrete outer wall screw rod hole sealing and blocking construction method. Compared with a conventional construction method, the concrete outer wall screw rod hole sealing and blocking construction method has the advantages that the operation process is simple; the implementation is easy; the concrete outer wall screw rod hole water seepage phenomenon is avoided; the anti-seepage effect of the construction method is good; the seepage due to improper screw rod hole sealing and blocking processing of the concrete outer wall surface is avoided; the engineering progress and the quality guarantee are facilitated; the repair cost due to seepage can be greatly reduced by the same concrete outer wall; and the cost is reduced.
Description
Technical field
The present invention relates to a kind of concrete exterior wall screw hole plugging structure.
The invention still further relates to a kind of concrete exterior wall screw hole plugging construction method.Be applicable to the construction of concrete exterior wall screw hole shutoff in civilian construction and industrial construction cast-in-situ concrete.
Background technology
Traditional concrete exterior wall screw hole, for the common quality defect preventing sealing hole imprecision from producing seepage, in screw hole, fill the method such as cement mortar or blowing agent shutoff, but in these two kinds of method application processes, water-proof plug hole effect is general, correspondingly adds the time of reprocessing and expense.
Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of concrete exterior wall screw hole plugging structure.
The technical problem that the present invention also will solve is to provide a kind of concrete exterior wall screw hole plugging construction method.
For solving the problems of the technologies described above; a kind of concrete exterior wall screw hole plugging structure of the present invention; comprise concrete exterior wall and screw hole; described screw hole is through concrete exterior wall cross section; injection hole is formed in the inside and outside both sides of screw hole; blowing agent is filled with in described screw hole; waterproofing mortar is injected for shutoff in the screw hole injection hole of blowing agent both sides; the lateral surface of described concrete exterior wall is brushed successively three road polyurethane water-proof paint layers, polyurethane water-proof paint layer outer brushing cement mortar protective course in Zai tri-road carrys out comprehensive shutoff screw hole.
The thickness of described waterproofing mortar is 30 ㎜.
The thickness of described polyurethane water-proof paint layer is 1 ㎜.
The thickness of described cement mortar protective course is 10 ㎜.
A kind of concrete exterior wall screw hole plugging construction method,
(1) pvc pipe is rejected: concrete exterior wall face die plate rejects pvc pipe with chisel after removing, and removes the residual slurry in reserving hole, blows off the grieshoch of the inside outside concrete exterior wall with little hair-dryer;
(2) waterproofing mortar shutoff: inject appropriate water with water jet in screw hole and keep fully moistening, inwardly waterproofing mortar is injected with special tool again after hole is slightly dry, the position of waterproofing mortar shutoff is that in concrete exterior wall, each 30 ㎜ in outside are thick, centre blowing agent tamps, inside outer wall screw hole outwards, compacting is floating for waterproofing mortar;
(3) blowing agent tamps: in concrete exterior wall, the middle blowing agent that adopts of outside waterproofing mortar shutoff tamps, after the waterproofing mortar sclerosis of inner side, blowing agent is squeezed in hole, when waiting blowing agent to solidify 60% soon, with instrument, outstanding blowing agent is compressed into hole, outside waterproofing mortar shutoff;
(4) water-repellent paint construction: after the waterproofing mortar sclerosis outside concrete exterior wall, brush the heterochromatic polyurethane water-proof paint that three road 1 ㎜ are thick in outside;
(5) topping construction: after above-mentioned water-repellent paint drying, at the cement mortar protective course that surface construction 10 ㎜ is thick, cement mortar protective course has been constructed rear reinforcement maintenance.
Beneficial effect of the present invention: compared with traditional construction method, operating process is simple, easy, stop concrete exterior wall screw hole infiltration phenomenon, this construction good seepage-proof property, stop the seepage that concrete exterior wall face is caused because screw hole shutoff process is not good at, be conducive to programming, guarantee quality, same concrete exterior wall can greatly reduce cause because of seepage reprocess expense, cost-saving.

Fig. 2 is the enlarged diagram at A place in Fig. 1.
Wherein: 1, concrete exterior wall, 2, screw hole, 3, injection hole, 4, blowing agent, 5, waterproofing mortar, 6, polyurethane water-proof paint layer, 7, cement mortar protective course.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment, only for explaining the present invention, does not form the restriction to protection scope of the present invention.
As illustrated in fig. 1 and 2, a kind of concrete exterior wall screw hole plugging structure of the present invention, comprise concrete exterior wall 1 and screw hole 2, screw hole 2 is through concrete exterior wall 1 cross section, in screw hole 2, outer both sides form injection hole 3, blowing agent 4 is filled with in screw hole 2, waterproofing mortar 5 is injected for shutoff in screw hole 2 injection hole 3 of blowing agent 4 both sides, the thickness of waterproofing mortar 5 is 30 ㎜, the lateral surface of concrete exterior wall 1 is brushed successively three road polyurethane water-proof paint layers 6, the thickness of polyurethane water-proof paint layer 6 is 1 ㎜, the comprehensive shutoff screw hole 2 of the outer brushing cement mortar protective course 7 of Zai tri-road polyurethane water-proof paint layer 6, the thickness of cement mortar protective course 7 is 10 ㎜.
A kind of concrete exterior wall screw hole plugging construction method,
(1) pvc pipe is rejected: concrete exterior wall face die plate rejects pvc pipe with chisel after removing, and removes the residual slurry in reserving hole, blows off the grieshoch of the inside outside concrete exterior wall with little hair-dryer;
(2) waterproofing mortar shutoff: inject appropriate water with water jet in screw hole 2 and keep fully moistening, waterproofing mortar 5 is inwardly injected with special tool again after hole is slightly dry, the position of waterproofing mortar 5 shutoff is that in concrete exterior wall, each 30 ㎜ in outside are thick, centre blowing agent 4 tamps, adopt the waterproofing mortar 5 of DP20 outside inside outer wall screw hole 2, compacting is floating;
