Abstract
The utility model discloses an outer wall screw hole plugging structure, which comprises a micro-expansion waterproof mortar cylinder filled in a screw hole and a micro-expansion waterproof mortar protruding square block plugged on the inner and outer wall surfaces around the screw hole; waterproof coating layers with certain thickness are coated on all surfaces of the convex square blocks and the wall surfaces at certain distances outside the outer edges of the convex square blocks, which are contacted with the inner wall surface and the outer wall surface; and a colloidal cement paste layer with a certain thickness is coated on the waterproof coating layer. The utility model has good water seepage prevention effect by synchronously plugging the screw hole and the hole and adopting the waterproof mortar added with the micro-expanding agent as the plugging material; the raised square blocks surrounding the screw hole play a role of a retaining dam, so that most of rainwater cannot directly enter the screw hole area, the water seepage rate of the outer wall is obviously reduced, and the post-maintenance cost of the project is reduced to a great extent.
Description
Technical field
The utility model is related to a kind of outer wall screw hole plugging structures.
Background technology
Current Domestic construction market external wall seepage problem generally existing, is a big common fault of residential housing, and anti-exterior wall oozes
Water is also a big difficulty, traditional foaming agent block screw hole cannot be guaranteed in building Life cycle can effectively by
Moisture is blocked in outside wall, and seeping water in the later stage, probability is big, and maintenance cost is high.
Utility model content
The purpose of this utility model is to solve to use foaming agent closure screw hole infiltration probability big at present, and maintenance cost is high
Technical problem.
To realize that the above purpose of utility model, the utility model provide a kind of outer wall screw hole plugging structure, including perfusion
In in screw hole microdilatancy waterproof mortar cylinder and be plugged in the microdilatancy waterproof mortar on inside and outside metope around screw rod hole
Raised square；
Certain distance on the outside of the outer edge that each face of the protrusion square and the raised square are contacted with inside and outside metope
Certain thickness waterproof coating layer is painted on metope；
Certain thickness colloidal state grout layer is painted on the waterproof coating layer.
Further, fiberglass gridding cloth is pasted on the colloidal state grout layer, on the fiberglass gridding cloth
It is painted with certain thickness mortar bed.
Further, the raised square on wall face is equipped with waterproof cover, and the waterproof cover is fixed on wall face
The raised square around, the waterproof cover will be including the raised square integral sealing.
Further, the vertical range of each side to the screw hole circumference of the raised square is 40-50mm.
Further, the thickness of the raised square is 10-15mm.
Compared with prior art, the utility model has the beneficial effects that：
The utility model is blocked by synchronous with the hole positions Wai Shuan in screw hole, and closure is that micro-expanding agent is added with material
Waterproof mortar, percolation-proof effect is good；Raised square around screw rod hole plays the role of checkdam, makes the major part of rainwater
It cannot directly enter screw hole region, it is ensured that external wall seepage rate is substantially reduced, thus after also largely reducing engineering
Phase maintenance cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is sectional view along A-A in Fig. 1.
In figure, microdilatancy waterproof mortar cylinder 1；Microdilatancy waterproof mortar protrusion square 2；Waterproof coating layer 3；Exterior wall 4.
Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figs. 1-2, the outer wall screw hole plugging structure of the utility model, including the microdilatancy that is poured into screw hole
Waterproof mortar cylinder 1 and it is plugged in the microdilatancy waterproof mortar protrusion square 2 on inside and outside metope around screw rod hole；
On the outside of the outer edge that each face of raised square 2 and raised square 2 are contacted with inside and outside metope on the metope of certain distance
It is painted with certain thickness waterproof coating layer 3, the area of waterproof coating layer 3 is bigger, and thickness is thicker, and water proofing property is better；
Certain thickness colloidal state grout layer is painted on waterproof coating layer 3, colloidal state cement mortar is mixed by cement and building adhesive
It closes.
Preferably, it is pasted with fiberglass gridding cloth on colloidal state grout layer, is painted on fiberglass gridding cloth certain
The mortar bed of thickness.
Preferably, the raised square 2 on wall face is equipped with waterproof cover（It is not shown in figure）, waterproof cover is fixed on wall face
On raised square 2 around, waterproof cover further increases water resistance by including 2 integral sealing of raised square.
Preferably, the vertical range of each side of raised square 2 to screw hole circumference is 40-50mm, the area of raised square 2
Bigger water proofing property is better.
Preferably, the thickness of raised square 2 is 10-15mm, and thicker water proofing property is better.
As shown in Figs. 1-2, multiple screw holes through exterior wall 4 are evenly equipped on exterior wall 4, screw hole spacing 45cm is sealed
Before stifled construction, the PVC casings rejected in screw hole are first bored with inflation, it is miscellaneous to clear up dust, pvc pipe in screw hole etc. with hair-dryer
Object.
When carrying out plugging construction, first watering wetting screw hole then will be by micro-expanding agent and waterproof mortar with thin mouth spray gun
The microdilatancy waterproof mortar being mixed into is poured into screw hole, screw hole is clogged closely knit；Then it constructs around screw rod hole
Screw rod hole is enclosed in it by raised square 2, and rainwater gear cannot be introduced into tunnel opening area outside；Subsequently prevented again
The construction of water paint layer 3, colloidal state grout layer, fiberglass gridding cloth and mortar bed, multilayer flashing structure ensure exterior wall never
Infiltration.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to which its technology is determined according to right
Property range.
