Abstract
An infiltration prevention method for a bolt hole in the outer wall of a reinforced concrete shear wall comprises the following steps: A, cleaning the surface of the bolt hole in the outer wall: taking out sundry in the bolt hole, removing ash residues in the hole and using water to fully wet the wall of the hole with water; B, using rigid cement mortar to fill and compact the bolt hole; C, cleaning and smoothening 30 mm around the bolt hole in the outer wall surface; D, horizontally and vertically brushing cold base oil to the bolt hole and the periphery of the bolt hole; E, cooling down the cold base oil for 3-5 minutes, and pasting PTO self-adhesive water-proof coiled materials; F, using a rubber mallet to uniformly hammer the PTO self-adhesive water-proof coiled material to enable the PTO self-adhesive water-proof coiled materials to be bonded firmly with the outer wall surface. The infiltration prevention method for the bolt hole in the outer wall of the reinforced concrete shear wall solves the problem that the indoor wall is contaminated by infiltration of the bolt hole in the outer wall, saves higher maintenance cost, reduces claim for compensation of a proprietor due to infiltration and improves the whole construction quality of projects.
Description
Technical field
The present invention relates to a kind of construction techniques, specifically, relate to a kind of reinforced concrete shear wall exterior wall bolt hole percolation-proof method.
Background technology
In the situation that existing job practices and technological means have inevitably stayed the through-wall bolt hole during construction shear wall.Therefore invented this technical patent for the shutoff at this position with the processing means that increase waterproofing course, avoided the pollution that interior decoration caused because of the infiltration of exterior wall bolt hole and reprocessed.
The method of processing at present shear wall exterior wall bolt hole in the industry is:
Adopt cement mortar to tamp in the both sides of bolt hole simultaneously, it is floating flat with structure metope one that bolt hole tamps the surface.After reaching intensity, mortar carries out metope (plaster, putty, coating, insulation) interior and exterior finishes etc. lower to operation.
There are the following problems for prior art:
(1) shutoff is closely knit fully.The original structure concrete shear force wall is generally C30～C40 concrete, and rear plugging material generally is cement mortar.There is the time interval of strength difference and construction in bi-material, each own contraction separately in the process that mortar strength and structural concrete strength increase simultaneously in the hole, its shrinkage stress opposite direction.At it separately in the process of gain in strength, the former bolt hole wall position Lock-in of joining at bi-material the slit.
(2) slit inevitably occurs after the bolt hole shutoff, but original construction technology has been ignored the processing to this position, has caused the hidden danger of infiltration.Simultaneously, the construction object of bolt hole plugging construction content is relatively discrete and quantity is very big, and mortar quality checking means are deficient and be difficult to accomplish absolutely check in the shutoff metapore.The shutoff quality of any one bolt hole slightly has deficiency, must seep water from this position in the future.
Summary of the invention
For above-mentioned deficiency of the prior art, the invention provides a kind of reinforced concrete shear wall exterior wall bolt hole percolation-proof method that prevents that the infiltration of exterior wall bolt hole from causing indoor wall to pollute.
The technical solution used in the present invention is:
A kind of reinforced concrete shear wall exterior wall bolt hole percolation-proof method, operating procedure is as follows:
The surface of A, External Wall bolt hole is cleared up: take out foreign material in the bolt hole, lime-ash in the cleaning hole, the abundant moistening hole wall of water;
B, real with filling up plug in the bolt hole with the hydraulic cement mortar;
Clear up smooth around C, the wall face bolt hole in the scope of 30mm;
Anyhow brush oil of the cold end around D, bolt hole and the bolt hole;
After hanging 3～5 minutes after E, the oil brushing of the cold end, paste the PTO adhesive waterproof coil;
F, the even hammering PTO of rubber hammer adhesive waterproof coil make PTO adhesive waterproof coil and wall face bonding firmly.
During described filling hydraulic cement mortar, carried out simultaneously by wall face and interior metope both sides.
Described PTO adhesive waterproof coil is cut into square according to the bolt hole size; PTO adhesive waterproof coil edge is greater than bolt hole edge 15mm.
The bolt hole surface of described filling hydraulic cement mortar is floating with trowel, and the bolt hole surface is bright and clean smooth all around with the bolt hole wall face.
The beneficial effect of the relative prior art of the present invention:
Reinforced concrete shear wall exterior wall bolt hole percolation-proof method of the present invention, having solved the indoor wall that in the past caused because of the infiltration of exterior wall bolt hole pollutes, saved higher maintenance cost, reduced because infiltration to owner's claim, has improved the integral construction quality of engineering.

The specific embodiment
The present invention will be described in detail referring to drawings and Examples:
A kind of reinforced concrete shear wall exterior wall bolt hole percolation-proof method, operating procedure is as follows:
The surface of A, External Wall bolt hole 3 is cleared up: take out bolt hole 3 interior foreign material, lime-ash in the cleaning hole, the abundant moistening hole wall of water;
B, real with filling up plug in the bolt hole 3 with the hydraulic cement mortar; Mortar strength is unsuitable excessive, and proportioning is (mass ratio) cement: medium sand: water=1:6:1, cement mortar moisture control be (can agglomeratingly throw away can scatter on the ground is advisable to be held in the hand) between 12%～13%;
Clear up smooth around C, wall face 1 bolt hole 3 in the scope of 30mm;
Anyhow brush oil of the cold end 5 around D, bolt hole 3 and the bolt hole;
After hanging 3～5 minutes after E, 5 brushings of oil of the cold end, paste PTO adhesive waterproof coil 6;
F, the even hammering PTO of rubber hammer adhesive waterproof coil 6 make that PTO adhesive waterproof coil 6 and wall face 1 are bonding firmly can to carry out the follow-up work such as external wall insulation stickup.
During described filling hydraulic cement mortar 4, carried out simultaneously by wall face 1 and interior metope 2 both sides.
Described PTO adhesive waterproof coil 6 is cut into square according to the bolt hole size; PTO adhesive waterproof coil 6 edges are greater than bolt hole 3 edge 15mm.
During reinforced concrete shear wall exterior wall bolt hole percolation-proof method construction of the present invention, the each household cost drops into increases by 25～75 yuan.But eliminated a hidden danger of quality, the expense of reprocessing of saving simultaneously and the economic results in society of increase are huge.
