Description
Technical field
The present invention relates to construction engineering technical field, specially a kind of high-layer shear force wall exterior wall upstream face Screw arbor with nut at both-ends hole envelope
Blocking method.
Background technique
At present in concrete structure pouring construction, it is substantially shear wall and frame structure, but in civil buildings
Shear wall structure is more, and shear wall is related to a large amount of Screw arbor with nut at both-ends construction, pours in shear wall slab during template support
It completes, after form removable, inner, external wall can all retain a large amount of Screw arbor with nut at both-ends hole, and interior wall Screw arbor with nut at both-ends hole is generally being plastered at present
It is blocked in the process with mortar, exterior wall Screw arbor with nut at both-ends hole is all using foam filled dose of injection as closure.
But foamed material density is low, fragile structure, the closure of Screw arbor with nut at both-ends hole often occurs and does not stand sternly, outside Screw arbor with nut at both-ends hole
Face end is rough and uneven in surface or because of external wall seepage situation caused by foamed material aging.
Summary of the invention
It is an object of the invention to solve classic screw hole mentioned above in the background art method for blocking to will appear to drawing
Screw hole blocks that not tight, Screw arbor with nut at both-ends hole alien invasion end is rough and uneven in surface or because of external wall seepage situation caused by foamed material aging
Problem.
To achieve the above object, the present invention provides a kind of high-layer shear force wall exterior wall upstream face Screw arbor with nut at both-ends hole method for blocking,
Including implementation steps in detail below:
Step 1, preparatory regularization produces PVC plastic conical plug in factory, and sets in the tail end of PVC plastic conical plug
Set conical plug anti-slip layer；
Step 2, construction point at the construction field (site) set up scaffold, auxiliary construction；
Step 3, rejects the plastic cushion of outer end in Screw arbor with nut at both-ends hole, and takes out Screw arbor with nut at both-ends；
Step 4 clears up sundries in Screw arbor with nut at both-ends hole, and wet in the watering of Screw arbor with nut at both-ends hole periphery；
Step 5 squeezes into PVC plastic conical plug at the Screw arbor with nut at both-ends hole port of shear wall slab upstream face；
Step 6, the filling-foam filler at the Screw arbor with nut at both-ends hole port of shear wall slab back side；
Step 7 carries out white washed wall operation, after clearing up shear wall slab outer surface of wall, moistens to metope, and linked network is smeared
Ash.
Preferably, in step 1, the point diameter of the PVC plastic conical plug is less than its tail end diameter, the PVC plastic
Expect that the tail end diameter of conical plug is equal with split bolt bore dia.
Preferably, in step 1, the conical plug anti-slip layer includes PVC plastic conical plug rear end surface and in PVC plastic
The interlaced a plurality of non-slip groove that material conical plug rear end surface opens up.
Preferably, in step 5, when squeezing into PVC plastic conical plug, first PVC plastic conical plug front end is inserted into drawing spiral shell
Rod aperture, and using the tail end of hand hammer percussion PVC plastic conical plug, make PVC plastic conical plug completely into Screw arbor with nut at both-ends hole, and
The tail end of PVC plastic conical plug is flushed with Screw arbor with nut at both-ends hole in the port of shear wall slab upstream face.
Preferably, in step 6, when the foam filled dose of injection Screw arbor with nut at both-ends hole, from PVC plastic conical plug with it is right
It draws and starts at the gap of screw hole inner wall, filled PVC plastic conical plug and Screw arbor with nut at both-ends hole after filler natural foaming to be foamed
The gap of inner wall, and closely knit screw hole.
Preferably, in step 7, when carrying out mesh plaster to shear wall slab exterior wall upstream face, cement mortar is attached to
The surface of conical plug anti-slip layer.
Preferably, described foam filled dose is cranny filler of polyurethane foam.
It is compared with prior art, the present invention having the following advantages and benefits:
1) the high-layer shear force wall exterior wall upstream face Screw arbor with nut at both-ends hole method for blocking is used by increasing PVC plastic conical plug
PVC plastic conical plug draws screw rod exit orifice to be blocked in alien invasion shear wall Screw arbor with nut at both-ends hole, insertion, then right from shear wall inside
It draws and injects foam filled dose at screw hole, shear wall Screw arbor with nut at both-ends hole is blocked in the way of the combination of inner and outside, it is ensured that PVC plastic
Conical plug tail end is tightly packed by the outer end in Screw arbor with nut at both-ends hole and is bonded completely with shear wall outer surface of wall, while conical plug is anti-skidding
Layer can effectively adhere to cement mortar.
2) high-layer shear force wall exterior wall upstream face Screw arbor with nut at both-ends hole method for blocking, by being hammered into shape at exterior wall upstream face screw hole
Enter PVC plastic conical plug, can be while guaranteeing to block quality, the filling with foam filled dose on the inside of outside cooperates, fastly
Speed is completed to block operation.
The method of the present invention is implemented simply, easy to operate, greatly reduces due to high-rise outer wall leakage scenarios, shortens engineering
Time-consuming reduces maintenance cost, improves construction quality, and solving classic screw hole method for blocking will appear Screw arbor with nut at both-ends hole envelope
It is stifled it is not tight, Screw arbor with nut at both-ends hole alien invasion end is rough and uneven in surface or because caused by foamed material aging the problem of external wall seepage situation.
