Description
Technical field
the present invention relates to the impervious method for blocking of a kind of shear wall screw hole through walls and structure, belong to architectural engineering construction technique field.
Background technology
shear wall, in work progress, needs to fix by the template of screw rod through walls by shear wall both sides, after building, is conveniently convenient to screw rod through walls releases from body of wall, and on screw rod through walls, cover has plastic pipe.When after the form removable of building shear wall, shear wall can leave the hole that cover has plastic pipe.In order to anti-hole seepage here, cause hidden dangers in project, need this screw hole through walls to carry out shutoff.Shutoff in the past directly cement mortar is daubed into from wall-through hole two ends in the process of plastering, effect low and in hole fill leakiness; Plastic bushing is not removed, and defines one separation layer in hole, makes wall-through hole be present in the hidden danger that seriously seeps water.
Summary of the invention
the object of the invention is to, the impervious method for blocking of a kind of shear wall screw hole through walls and structure are provided.In shear wall screw hole shutoff through walls process, current national codes can be made up not to the blank of its Uniform provisions, its processing method of specification and acceptance criteria, guarantee that exterior wall leakproof provides effective measure guarantee, improve effect, remove a hidden danger, economic environmental protection.
technical scheme of the present invention:
the impervious method for blocking of a kind of shear wall screw hole through walls, the method operates according to the following steps:
a, employing are impacted electric hammer and are smashed by plastic bushing in screw hole through walls;
b, round steel is utilized to remove clean by plastic residues in screw hole through walls;
c, utilize air compressor air gun by screw hole through walls dust blow down;
d, water pistol is utilized to clean up in screw hole through walls;
in E, shear wall apertura lateralis after the drying, plug is set;
f, utilize water pistol will spray plain-water slurry in screw hole through walls together;
g, inside shear wall, utilize air compressor by the expansive cement mortar injection hole for preparing;
h, to receive after water until cement mortar, two ends adopt the sealing of 1:2 dry cement mortar, fill in closely knit;
i, finally to sprinkle water maintenance, enter next process.
in preceding method, in described steps A, the length of the bit is greater than shear wall's thickness 100mm and is advisable, and drill bit specification is identical with plastic bushing external diameter.
in preceding method, in described step B, the diameter of round steel is identical with screw diameter through walls.
in preceding method, in described step e, plug is positioned at exit orifice 20mm position, and plug is the silicone weather resistant structure glue of thickness 20mm.
in preceding method, described plug adopts glue rifle to inject.
in preceding method, in described step G, inside shear wall, 20mm shutoff space is reserved in aperture.
according to the impervious plugging structure of shear wall screw hole through walls that preceding method is formed, the outer aperture Nei Chu of described shear wall screw hole through walls is provided with plug, be provided with expansive cement mortar in shear wall screw hole through walls, the inner orifice of shear wall screw hole through walls and outer aperture are provided with cement mortar sealing.
in aforementioned structure, described plug is positioned at exit orifice 20mm position, and plug is the silicone weather resistant structure glue of thickness 20mm.
in aforementioned structure, the thickness of described cement mortar sealing is 20mm.
compared with prior art, the present invention can reserve in screw hole plugging construction process through walls in shear wall structure and make up current national codes not to the blank of its Uniform provisions, its processing method of specification and acceptance criteria, guarantee that exterior wall leakproof provides powerful guarantee, improve effect, remove a hidden danger, economic environmental protection.Meanwhile, also reference value can be provided for similar engineering construction.
