Description
The application is application number: 2013102614643；The applying date: 2013-06-26；Denomination of invention: the divisional application of " a kind of external wall bolt hole Seepage method ".
Technical field
The present invention relates to a kind of building hole anti-seepage construction method, particularly relate to external wall shear wall formwork bolt hole waterproof plugging construction technology.
Background technology
In frame-shear structure construction, install in process as ensureing template strength and rigidity at shear wall formwork, it is prevented that the generation of occur in casting concrete process the rising quality accidents such as mould, spillage, template deformation, adopting split bolt to reinforce is necessary means and measure.Simultaneously in order to accelerating construction progress and construction are convenient, current unit in charge of construction is commonly used adds the reusable split bolt of sleeve pipe.Thus causing shear wall split bolt position to produce artificial hole.According to conventional slurry method for blocking, exterior wall leakage phenomenon very easily occurring, impact uses function and attractive in appearance.
Summary of the invention
The technical problem to be solved is just to provide a kind of construction method effectively preventing external wall bolt hole from seeping water.
The present invention adopts the following technical scheme that
A kind of external wall shear wall bolt hole Seepage method, comprises the steps:
(1) aperture, medial and lateral in shear wall bolt hole being picked cutter, so as to form " V " type mouth, clear up backlash water-wet, when vent surface is without open fire, with Polymer cement materials, apertura lateralis mouth is blocked, compacting is floating；
(2) after the Polymer cement materials in aperture, outside reaches three days intensity, bolt hole is finely cleared up, rubbish and floating ash in cleaning hole；By in microdilatancy type chemical adhesive hand-hole after cleaning, then by the straight section reinforcing bar implant holes that makes in advance, make in hole full；
(3) after bolt hole bar planting completes 48 hours, check outside closure bolt hole, whether the Polymer cement materials in aperture has loosening, repair in time if any loosening, after completing, adhesive excessive for aperture inside bolt hole is cleaned out, and with aperture, clear water moistening inner side, after completing, aperture, inner side Polymer cement materials is blocked, floating；
(4) the basic unit's laitance around aperture outside bolt hole, foreign material are cleaned out, and within the scope of 200mm, shear wall surfacing is not more than 9% without convex-concave, dry, water content around aperture, outside, at the uniform brushing base treatment agent of apertura lateralis mouth after completing, treat that base treatment agent is dried, SBS coiled material is positioned, adopt hot melt paving method, make the asphalt melting of SBS coiled material bottom surface, be firmly bonded with base treatment agent.
Further, in step (1), utilize external scaffolding as construction operation platform.
Further, in step (1), clear up " V " type mouth with palm fiber brush.
Further, in step (2), bolt hole is carried out fine cleaning and includes adopting compression air to carry out 35 cleanings, rubbish in cleaning hole repeatedly；Then with cotton or hairbrush, floating for hole wall ash is cleaned.
Further, in step (2), adopt manual slip casting machine by microdilatancy type chemical adhesive hand-hole.
Further, in step (2), injecting glue amount is the 50% of pore volume.
Further, in step (2), implanting reinforcing bar length and subtract 60mm equal to shear wall's thickness, bar list edema over the face rust should be cleaned out, and exposes metallic luster.
Further, in step (4), SBS coiled material is the fritter of 150mm × 150mm.
Further, in step (4), light flame gun or blowtorch baking SBS coiled material bottom surface and the junction of base treatment agent, make the asphalt melting of SBS coiled material bottom surface.
Further, in step (4), block-type SBS coiled material periphery should take the measure of rolling.
The invention has the beneficial effects as follows:
External wall shear wall bolt hole disclosed in this invention Seepage method, simple to operate, by four layers of waterproof blocking processing measure, it is prevented effectively from the infiltration of external wall bolt hole.
Accompanying drawing explanation
Fig. 1 is the profile of the external wall bolt hole after using the construction method disclosed in the embodiment of the present invention 1 to process.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
Embodiment 1, refer to Fig. 1, present embodiment discloses a kind of external wall shear wall bolt hole Seepage method, comprises the steps:
