Description
Technical field
the utility model relates to the external wall structure in a kind of shutoff screw rod hole, belongs to construction work wall construction technical field.
Background technology
in construction work decorations construction, exterior wall and masonry wall are plastered simultaneously often, and the amount of plastering is large, long construction period, if and exterior wall basal plane is dealt with improperly, easily produce hollowing, crack, in this case, cancel external wall plastering, especially cancel plastering of exterior 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, after having lost one floated coat, very easily there is seepage in position, screw rod hole in concrete exterior wall, therefore prior art scheme is very undesirable.
Summary of the invention
the purpose of this utility model is: the external wall structure in a kind of shutoff screw rod hole is provided, can significantly reduces costs, increase work efficiency, accelerating construction progress.Also can prevent that concrete exterior wall is after having lost one floated coat, the possibility of seepage occurs in position, screw rod hole, improve the whole antiseep ability of external wall, to overcome the deficiencies in the prior art.
the technical solution of the utility model
the external wall structure in a kind of shutoff screw rod hole, comprise exterior wall and screw rod hole, screw rod hole is through exterior wall cross section, it is characterized in that: in screw rod hole, outer both sides are carried out reaming by machinery and are formed trumpet type injection hole, foamed glue is injected in screw rod hole, after filling with screw rod hole, injects foamed glue dry waterproofing mortar for shutoff in the injection hole in screw rod hole, the surface of the dry waterproofing mortar of both sides and metope are given prominence to 1mm～3mm, the part dry waterproofing mortar of outstanding metope is that cake structure its diameter are 45mm～60mm, then on two sides, screw rod hole, brushing polymer cement-based waterproof is filmed.
in the external wall structure in aforementioned shutoff screw rod hole, the external diameter of described trumpet type injection hole is 30mm～40mm, and the degree of depth is 20mm～30mm.
in the external wall structure in aforementioned shutoff screw rod hole, the scope of filming that described brushing polymer cement-based waterproof is filmed is the center of circle for take center, screw rod hole, the border circular areas that diameter is 100mm～200mm, and its coating thickness is 1mm～3mm.
compared with prior art, existing structure has floated coat on exterior 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, the present invention has cancelled the particularly floated coat on exterior wall of exterior 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 improved the whole antiseep ability of external wall.
Accompanying drawing explanation
accompanying drawing 1 is construction schematic diagram one of the present utility model;
accompanying drawing 2 is construction schematic diagrames two of the present utility model;
being labeled as in accompanying drawing: the scope of the filming diameter that 1-exterior wall, 2-screw rod hole, 3-trumpet type injection hole, 4-foamed glue, 5-dry waterproofing mortar, 6-polymer cement-based waterproof are filmed, a-trumpet type injection hole external diameter, the b-trumpet type injection hole degree of depth, c-polymer cement-based waterproof are filmed, the coating thickness that d--polymer cement-based waterproof is filmed.
The specific embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.
the utility model is formed according to the rapid plugging method in following a kind of exterior wall screw rod through walls hole, the method of this exterior wall screw rod through walls hole quick blocking construction is in medial and lateral, external wall screw rod through walls hole, to do the shutoff of dry waterproofing mortar and waterproof coating processing, filling-foam glue in the middle of hole, reach the effect of five heavy waterproof, concrete method for blocking comprises the following steps:
step 1, reaming and cleaning; Exterior wall screw rod holes blocking through walls will be rejected the finished product plastic cushion at Screw arbor with nut at both-ends two ends before processing, to not using the screw rod hole of finished product plastic cushion to form trumpet type injection hole from outside with mechanical hole reaming, and the PVC pipe of reaming part is removed, the external diameter of mechanical hole reaming is 30mm～40mm, the degree of depth is 20mm～30mm, trumpet type injection hole wire brushing is thorough, after having rinsed, should remove ponding and keep moisture state
step 2, dry waterproofing mortar are made; What dry waterproofing mortar adopted is 1:2 dry cement mortar, and in dry cement mortar, mixes waterproof agent and expansion agent, reaches the effect that prevents shrinkage crack and reach waterproof.
step 3, the shutoff of screw rod hole; First with dry waterproofing mortar, inject trumpet type injection hole outside screw rod hole, after completing also final set, to screw rod hole, injects again by this place's dry waterproofing mortar foamed glue, filling-foam glue must be filled into body of wall middle part and fill closely knit from the trumpet type injection hole of inner side, screw rod hole, until foamed glue overflows a part from inner side, foamed glue is filled and completely with dry waterproofing mortar, to be carried out shutoff inside screw rod hole again, wherein mortar shutoff must be full closely knit, guarantees with original structure concrete binding firm; Mortar should carry out maintenance in time, and check whether have crack or hollowing, appearance hollowing or crack should be rectified and improved immediately, the sealed depth of dry waterproofing mortar is consistent with the trumpet type injection hole degree of depth, and the surface of dry waterproofing mortar is than the outstanding 1mm～3mm of metope after the shutoff of both sides, screw rod hole, the part dry waterproofing mortar of outstanding metope is that cake structure its diameter are 45mm～60mm.
step 4, waterproofing course are processed; On the dry waterproofing mortar of both sides, screw rod hole and body of wall, all should film by brushing polymer cement-based waterproof, and the polymer cement-based waterproof scope of filming of filming is the center of circle for take center, screw rod hole, diameter is the border circular areas of 100mm～200mm, and its coating thickness is 1mm～3mm.。
