Specifically, the resilient plug is rubber stopper.
Further, the screw hole offers horn mouth in outside.
Further, the resilient plug is partial to the exterior wall outside and is set, and is abutted with horn mouth position.
Specifically, the waterproof coating layer is from cement-base waterproof coating layer, thickness is 0.5-2mm, a diameter of 100-
200mm。
Specifically, the horn mouth is 15-20mm along the length of inner side of outer wall to exterior wall lateral direction.
The exterior wall that a kind of device blocked for outer wall screw hole and screw hole provided by the utility model are blocked
Structure, can bring following at least one beneficial effect：
1st, screw hole is pressed into using resilient plug, connecting the elastic-restoring force for producing by interference is fastened in screw hole, and
Completely cut off interior or exterior space, can bear >=hydraulic pressure of 20MPa is strong, effectively prevent the Seepage after the closure of outer wall screw hole,
One-time-reach-place, saves and reprocesses cost.
2nd, inner side foaming agent and outside waterproof mortar are separated by resilient plug, and because resilient plug is fastened in screw hole
, injection foaming agent is carried out again after being hardened without waiting for waterproof mortar, and can be construction simultaneously.And outside waterproof cement mortar
Hardening generally needs 2~3 days, significantly shortens the duration, reduces time cost and labor cost.
3rd, the price of elastic component is more cheap, will not increase engineering cost.
4th, it is simple and easy to apply using the structural traps screw hole.
In addition, a kind of construction method of outer wall screw hole closure is also disclosed, it is divided into following four step：
The first step, outer flare
After concrete exterior wall face die plate is removed, enlarging is carried out to outside screw hole with jump bit, dig flue, cleaning hole
Residue, dust in hole.
Second step, is pressed into rubber stopper
Rubber stopper is pressed into horn mouth root.
3rd step, waterproof cement mortar closure and filling-foam agent
Screw hole on the outside of rubber stopper, it is bell-mouthed fully wet to ensure to suitable quantity of water is sprayed into horn mouth with water jet
Profit, is filled after horn mouth is slightly dry with waterproof cement mortar, is compacted from inside to outside floating.
At the same time, to injection foaming agent in the screw hole on the inside of rubber stopper until overflowing inner side of outer wall metope, it is ensured that fill out
Fill closely knit, press flat with finger when foaming agent somewhat solidifies.
4th step, cement-base waterproof coating construction
After outside waterproof cement mortar is dried, exterior wall lateral surface smears cement-base waterproof coating, diameter 100mm after 1mm.
