Abstract
The utility model discloses a concrete outer wall bolt hole leakproof structure, which comprises an outer wall body, a bolt hole and a rubber piston, wherein the bolt hole and the rubber piston are obligated in a wall, the rubber piston is embedded in the middle segment of the bolt hole, the rubber piston fills expended waterproof mortar which is mixed with expanding agent with 15% cement content into the bolt hole which is arranged toward the direction of an outer wall, and the rubber piston fills 1:3 harsh cement mortar into the bolt hole which is arranged toward the direction of an inner wall. Polymer cement (JS) waterproof coating is coated on a hole mouth of the bolt hole of the outer wall, the diameter of the rubber piston is bigger 1.5-2mm than the diameter of a casing pipe, and the depth of the rubber piston embedded into the bolt hole is equal or greater than half of the thickness of a wall body. A concrete outer wall bolt hole uses a three-layer seal structure, and cuts off water seepage channels and water leakage channels, thereby enabling the outer wall to be successful to prevent seeping in one time, eliminating a repair phenomenon, guaranteeing use function, and preventing economic loss caused by repair treatment because of leakage.
Description
Technical field
The utility model relates to a kind of concrete exterior wall bolt hole anti-leakage structure.
Background technology
Exterior wall leakage is one of common quality defect that affects the house normal usage function, especially one of focal issue of customer complaint.Particularly in the Shear Wall Structure Construction, in order to satisfy the formwork requirement, template need to arrange the set bolt of some when installing.Deal with improperly because of the split bolt hole again after the form removal, often stayed external wall seepage hidden danger even long-term seepage.Not only difficulty of construction is large if again process breakthrough in the house use procedure, and expense is high, and the cycle is long.Untimely processing will cause body of wall infringement, decorative layer cracking, outward appearance to be polluted, and has had a strong impact on use function and the life-span of building.
The seepage process of exterior wall bolt hole its essence is water in the pressure-acting process at bolt hole place, and the key of therefore pre-antiseep is exactly the path that cuts off rainwater in fact, stops the transmission of water pressure.
Traditional method for blocking is to adopt dry cement mortar layered tamping:
The shortcoming of this method is in the mortar hardening process, along with the drying of mortar is shunk, easily forms the micro-cracks of infiltration between mortar and hole wall, very easily forms and oozes passage.
Adopt the single mortar laminated plugging method of micro-expansion cement: the very difficult control of the expansion rate of expansion agent and assurance, when autogenous shrinkage behind the mortar hardening and expansion are uneven, easily form the contraction microcrack at the hole wall place, produce the weak spot of seepage; In addition, plug is filled out many factors artificial in the operation, and whether whether plug is filled out closely knit, clear up in the hole and totally waterproof is all had a significant impact.According to construction experience ago, adopt the exterior wall bolt hole of this kind method shutoff, all there are to some extent some breakthroughs.Can not guarantee waterproof quality.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of concrete exterior wall bolt hole anti-leakage structure.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: concrete exterior wall bolt hole anti-leakage structure, comprise outer wall body and the bolt hole of reserving within the walls, and be embedded with the PVC sleeve pipe in the bolt hole, also comprise rubber stopper; Rubber stopper is embedded in the inside in bolt hole stage casing; Rubber stopper expansion waterproofing mortar of water mixing mud consumption 15% expansion agent in the filling in the bolt hole of exterior wall direction; Rubber stopper is filling 1:3 dry cement mortar in the bolt hole of interior wall direction.
As preferably, exterior wall bolt hole hole place's brushing water-repellent paint.
As preferably, the rubber stopper diameter is than the large 1.5～2mm of diameter of PVC sleeve pipe pre-buried in the bolt hole.
As preferably, the degree of depth in rubber stopper stud bolt hole is not less than 1/2 of thickness of wall body.
The beneficial effects of the utility model are:
The concrete exterior wall bolt hole has been adopted three seal structures, blocked ooze, leak paths, outer wall impermeable is leaked accomplishes once success, stopped to reprocess the generation of phenomenon, guaranteed the use function.Avoided doing over again because of seepage and processed the economic loss cause.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model concrete exterior wall bolt hole anti-leakage structure embodiment.
Among the figure, 1-rubber stopper, 2-bolt hole, 3-recess, 4-exterior wall, 5-water-repellent paint, 6-expansion waterproofing mortar, 7-dry cement mortar, 8-interior decoration layer.
The specific embodiment
1, technological process:
The bolt hole drill removes, and------the nose end concrete is cut a hole into splayed, and------the pressure waterproofing mortar is smeared in layering---brushes water-repellent paint---exterior wall base treatment---shutoff interior wall bolt hole to nose end concrete base treatment to embed rubber stopper
2, as shown in Figure 1, operating procedure is as follows:
1) first with electric drill will be within the walls in the bolt hole 2 pre-buried PVC Sleeve drill remove: used bit diameter is slightly larger than PVC sleeve pipe external diameter, and the degree of depth of boring except the PVC sleeve pipe is not less than 2/3 of wall thickness;
2) with rubber stopper 1 stud bolt hole 2: used rubber stopper 1 is cylinder, and diameter is than the large 2mm of PVC casing diameter, and the degree of depth in stud bolt hole is not less than 1/2 of thickness of wall body;
3) cutter flue recess 3 is picked with little chisel in bolt hole 2 outer ends, and the degree of depth is not less than 20mm, and outside diameter is not less than 50mm;
4) hole base treatment: the loose concrete after will cutting is removed, and floating ash in the hole is rinsed well, also waters in advance the outer end face bristle moistening with wire brush.Divide the expansion waterproofing mortar that is laminated into interior water mixing mud consumption 15% expansion agent in exterior wall 4 one side direction bolts hole, at hole scope brushing two road JS water-repellent paints 5, the coating area is not less than 100mm * 100mm after mortar final set;
5) exterior wall base treatment: after the shutoff of exterior wall screw hole was complete, External Wall basic unit cleared up and sprinkles water moisteningly, and the metope large tracts of land is criticized and scraped interfacial agents after water is received on the surface, then carries out the construction of decoration of exterior wall layer.
6) shutoff of inner wall one side bolt hole: before the side is whitewashed within the walls, adopt 7 layerings of 1:3 dry cement mortar to get final product the bolt hole shutoff is closely knit, do not need to carry out specially treated and can satisfy waterproof requirement.
In Fig. 1, after the above-mentioned steps processing, rubber stopper 1 is positioned at the middle part of bolt hole 2, the outer wall one side filling expansion waterproofing mortar 6 of bolt hole 2 interior rubber stoppers, the inner wall one side filling dry cement mortar 7 of bolt hole 2 interior rubber stoppers, interior wall also scribbles interior decoration layer 8.
Above-described the utility model embodiment does not consist of the restriction to the utility model protection domain.Any modification of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present utility model.
