Abstract
The invention discloses a seepage-proof construction method for a bolt hole. The seepage-proof construction method for the bolt hole comprises the following steps of (1) trimming and digging an internal side hole and an external side hole of the bolt hole of a shear wall to form into a V-shaped opening, filling water to enable the V-shaped opening to get wet after being cleared, plugging the external side hole with polymer cement waterproof mortar when the surface inside the hole is not provided with visible water and compacting and trowelling; (2) performing fine clearing on the bolt hole after the polymer cement waterproof mortar at the external side hole achieves three-day intensity; (3) detecting whether the polymer cement waterproof mortar at the external side hole gets loose or not 48 hours after steel bar embedment and plugging and trowelling the internal side hole with the polymer cement waterproof mortar; (4) enabling pitch on the bottom surface of SBS (Styrene Butadiene Styrene) coiled materials to be melted to be firmly bonded with the base primer through a hot melting paving method. The seepage-proof construction method for the bolt hole is simple in operation and effectively avoids bolt hole of the building external wall from water seepage due to the four-layer waterproof blocking treatment measures.
Description
Technical field
The present invention relates to a kind of building hole anti-seepage construction method, relate in particular to external wall shear wall formwork bolt hole waterproof plugging construction technology.
Background technology
In frame structure building operations, install in process as ensureing template strength and rigidity at shear wall formwork, prevent from occurring in concreting process the rising generation of the quality accidents such as mould, spillage, template deformation, adopting split bolt to reinforce is necessary means and measure.Simultaneously convenient with construction for accelerating construction progress, unit in charge of construction generally adopts and adds the reusable split bolt of sleeve pipe at present.Thereby cause shear wall split bolt position to produce artificial hole.If adopt conventional slurry method for blocking, very easily there is exterior wall leakage phenomenon, impact is used function and attractive in appearance.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of construction method that effectively prevents the infiltration of external wall bolt hole
The present invention adopts following technical scheme:
A kind of external wall bolt hole Seepage method, comprises the steps:
(1) cutter is picked in the aperture, medial and lateral in shear wall bolt hole, make it to form " V " type mouth, cleaning backlash water-wet, vent surface is during without open fire, apertura lateralis mouth carried out to shutoff with polymer cement waterproof mortar, and compacting is floating;
(2) the polymer cement waterproof mortar in aperture, outside reaches after three days intensity, and bolt hole is carried out to meticulous cleaning, rubbish and floating ash in cleaning hole; After cleaning, by microdilatancy type chemical adhesive injection hole, then the straight section reinforcing bar of making is in advance implanted in hole, made in hole full;
(3) bolt hole bar planting completed after 48 hours, outside inspection shutoff bolt hole, whether the polymer cement waterproof mortar in aperture has loosening, repair in time if any loosening, after completing, the excessive bonding adhesive in aperture inside bolt hole is cleaned out, and with aperture, the moistening inner side of clear water, after completing, aperture, inner side is used to polymer cement waterproof mortar shutoff, floating;
(4) basic unit's laitance, the foreign material around of aperture outside bolt hole are cleaned out, and aperture, outside around in 200mm shear wall surfacing without convex-concave, be dried, water content is not more than 9%, after completing at the even brushing base treatment agent of apertura lateralis mouth, after base treatment agent is dry, SBS coiled material is positioned, adopt hot melt paving method, make the asphalt melting of SBS coiled material bottom surface, firm with base treatment agent bonding.
Further, in step (1), utilize external scaffolding as construction operation platform.
Further, in step (1), with palm fiber brush cleaning " V " type mouth.
Further, in step (2), bolt hole is carried out to meticulous cleaning and comprise that employing compressed air carries out 3-5 cleanings repeatedly, rubbish in cleaning hole; Then with cotton or hairbrush, floating hole wall ash is cleaned.
Further, in step (2), adopt manual slurry filling machine by microdilatancy type chemical adhesive injection hole.
Further, in step (2), injecting glue amount is pore volume 50%.
Further, in step (2), implantation reinforcing bar length equals shear wall thickness and subtracts 60mm, and the floating rust of rebar surface should be cleaned out, and exposes metallic luster.
Further, in step (4), the fritter that SBS coiled material is 150mm × 150mm.
Further, in step (4), light the junction of flame gun or blowtorch baking SBS coiled material bottom surface and base treatment agent, make the asphalt melting of SBS coiled material bottom surface.
Further, in step (4), piece type SBS coiled material periphery should be taked the measure of rolling.
The invention has the beneficial effects as follows:
External wall bolt hole Seepage method disclosed in this invention, simple to operate, by the measure of four layers of waterproof blocking processing, effectively avoid the infiltration of external wall bolt hole.
Brief description of the drawings
Fig. 1 is the sectional drawing that uses the disclosed construction method of the embodiment of the present invention 1 external wall bolt hole after treatment.
