Abstract
The utility model discloses a rapid blocking structure of a screw hole of a concrete structure outer wall. The rapid blocking structure comprises the shear wall and the screw hole, wherein the screw hole penetrates through the section of the shear wall, the inner side and the outer side of the screw hole are broadened through machines to form a horn-shaped injection hole, polystyrene foam is injected into the screw hole, the injection hole of the screw hole is filled with dry hard waterproof mortar for blocking after the screw hole is filled with the polystyrene foam, the two side surfaces of the dry hard waterproof mortar are flush with the inner surface and the outer surface of the shear wall respectively, and the outer side face of the screw hole is coated with a polymer cement-based waterproof coating film. By the rapid blocking structure, cost is largely lowered, working efficiency is improved, and structure progress is accelerated. Leakage of the screw hole caused after a plaster layer is removed from the concrete outer wall can be prevented, and the overall leakage preventing capacity of the building outer wall is improved.
Description
Technical field
the utility model relates to the quick blocking structure in a kind of concrete structure outer screw rod hole, belongs to construction work wall construction technical field.
Background technology
in construction work decorations construction, shear wall and masonry wall are plastered simultaneously often, and the amount of plastering is large, long construction period, if and shear wall basal plane is dealt with improperly, easily produce hollowing, crack, in this case, cancel shear wall and plaster, especially cancel plastering of outer shear wall, cost-saved, accelerating construction progress, reduces the probability that work high above the ground accident occurs.If but building concrete exterior wall is cancelled and being plastered, concrete exterior wall is losing after one floated coat, in position, screw rod hole, seepage very easily occurs, therefore prior art scheme is very undesirable.
Summary of the invention
the purpose of this utility model is: a kind of concrete structure outer screw rod hole quick blocking structure is provided, significantly to reduce costs, increase work efficiency, accelerating construction progress, and prevent that concrete exterior wall from losing the possibility that seepage occurs after one floated coat, in position, screw rod hole, thereby improve the overall antiseep ability of external wall and overcome the deficiencies in the prior art.
the technical solution of the utility model:
the quick blocking structure in a kind of concrete structure outer screw rod of the present utility model hole is, this structure comprises shear wall and screw rod hole, screw rod hole is through shear wall cross section, carry out reaming in the inside and outside both sides in screw rod hole by machinery and form trumpet type injection hole, foamed glue is injected in screw rod hole, after filling screw rod hole, injects foamed glue stiff type waterproofing mortar for shutoff in the injection hole in screw rod hole, the surface of the stiff type waterproofing mortar of both sides is concordant with the inside and outside surface of shear wall, then brushing polymer cement-based waterproof film on the lateral surface of screw rod hole.
in aforementioned structure, the external diameter of described trumpet type injection hole is 30mm～50mm, and the degree of depth is 10mm～40mm.
in aforementioned structure, the film scope of described brushing polymer cement-based waterproof film 6 is taking center, screw rod hole as the center of circle, the border circular areas that diameter is 100mm～200mm, and its coating thickness is 1.5mm～5mm.
in aforementioned structure, the degree of depth in the outside, injection screw rod hole of described stiff type waterproofing mortar is 40mm～60mm, and the degree of depth of the inner side, injection screw rod hole of described stiff type waterproofing mortar is 20mm～40mm.
owing to having adopted technique scheme, the utility model compared with prior art, structure of the prior art has floated coat on shear wall and masonry wall in decoration construction, the amount of plastering is large, long construction period, easily produce hollowing or crack, particularly the position, screw rod hole of concrete wall is because wall leakage very easily occurs for method for blocking and improper measures, and the utility model has been cancelled the particularly floated coat on outer shear wall of shear wall, can significantly reduce the amount of plastering, reduce the cost of plastering, increase work efficiency, accelerating construction progress, can reduce the possibility of floated coat hollowing or cracking simultaneously, save maintenance cost, particularly improve the overall antiseep ability of external wall.
Brief description of the drawings
accompanying drawing 1 is the structural representation of quick blocking structure of the present utility model before shutoff;
accompanying drawing 2 is the structural representations after the utility model shutoff.
being labeled as in accompanying drawing: 1-shear wall, 2-screw rod hole, 3-trumpet type injection hole, 4-foamed glue, the stiff type waterproofing mortar of 5-, 6-polymer cement-based waterproof film.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to any restriction of the present utility model.
embodiment of the present utility model: the utility model is constructed according to the rapid plugging method in following a kind of concrete structure outer screw rod hole, and the rapid plugging method in this concrete structure outer screw rod hole is by comprising following construction sequence:
step 1, after the concreting of shear wall completes and wall form is removed, leave and connect the screw rod hole of body of wall at the position of template-setup Screw arbor with nut at both-ends concrete wall, there is glue cup at hole, both sides, hole wall is pvc pipe;
foreign material rubbish in step 3, cleaning eye, and moistening at inside and outside both sides, screw rod hole place water;
step 4, perfusion foamed glue: toward screw rod hole, squeeze into foamed glue from screw rod hole inner side, when the foamed glue that injects screw rod hole reaches outside screw rod hole, from the dry waterproofing mortar shutoff of outside, screw rod hole, continue to squeeze into foamed glue until fill immediately;
process step 5, inner side, screw rod hole: the dry waterproofing mortar shutoff of inner side, screw rod hole;
process in step 6, outside, screw rod hole: brushing polymer cement-based waterproof film is in outside, screw rod hole.
in wherein said step 2, mechanical hole reaming is shaped as trumpet type, and the reaming degree of depth is 10mm～40mm, external diameter is 30mm～50mm, in described step 4, outside screw rod hole, use the shutoff of dry waterproofing mortar, its sealed depth is 40mm～60mm, in described step 5, inside screw rod hole, use the shutoff of dry waterproofing mortar, its sealed depth is 20mm～40mm, in described step 6, brushing polymer cement-based waterproof film is in outside, screw rod hole, its film scope is taking center, screw rod hole as the center of circle, diameter is the border circular areas of 100mm～200mm, its coating thickness is 1.5mm～5mm.
