Abstract
The utility model belongs to the technical field of sealing water stopping tape and discloses puncture-proof pre-laid reverse-adhesion water stopping tape, which is characterized by comprising a water stopping tape body. A puncture-proof pre-laid reverse-adhesion layer is covered outside the water stopping tape body. The puncture-proof pre-laid reverse-adhesion layer can conduct a series of physical and chemical reactions with pouring concrete, thereby enabling the water stopping tape and the concrete to be firmly bonded together. After the concrete solidifies, the puncture-proof pre-laid reverse-adhesion layer has certain fluidity. Thus, after the water stopping tape is punctured, the puncture-proof pre-laid reverse-adhesion layer can flow automatically to repair the water stopping tape. When the area of the section of the water stopping tape changes due to the fact that the water stopping tape is stretched or extruded, the puncture-proof pre-laid reverse-adhesion layer can adapt to change of the area of the section automatically to fill gaps or flow to other positions, thereby enabling the concrete and the water stopping tape to be closed well and avoiding water leakage.
Description
Technical field
The utility model belongs to rubber seal waterstop technical field, relates in particular to a kind of anti-piercing through and overlays anti-sticking formula waterstop.
Background technology
In engineerings such as subway, tunnel and water conservancy, constuction joint and deformation joint generally need be provided with waterstop.Most rubber, plastics or other synthesized polymer materials of adopting of the waterstop that uses are at present processed, and have following defective: one of which, and existing waterstop top layer is rubber or plastics, rubber or plastics and concreting are together the time, and is bonding insecure; Its two, be prone to puncture, original waterstop product is in concrete placement, partly or entirely to water to be embedded in the concrete, but many stone and sharp keen steel bar ends that have wedge angle are easy to pierce through waterstop in the concrete.Because the tearing strength specific tensile strength of plastics and rubber is little, in a single day waterstop is pierced or tears, and breach enlarges easily under external force, causes waterstop to lose efficacy; Its three, easy to leak, waterstop sectional area after receiving stretching action can diminish, the concrete after making waterstop and solidifying separates, and forms the gap, water can infiltrate in the gap.Application life is shorter.
The utility model content
The technical problem that the utility model will solve just provides a kind of good seal performance, self-reparing capability anti-piercing through strong, long service life overlays anti-sticking formula waterstop.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: comprise the waterstop body, be enclosed with anti-piercing through in the outside of described waterstop body and overlay anti-adhesion coating.
Anti-the piercing through that the utility model provided overlays anti-sticking formula waterstop compared with prior art; Have the following advantages: owing to comprise the waterstop body; Be enclosed with anti-piercing through in the outside of described waterstop body and overlay anti-adhesion coating; Anti-piercing through overlays anti-adhesion coating and can a series of physics and chemical reaction take place with concreting, makes firm the bonding together of waterstop and concrete; Anti-piercing through overlays anti-adhesion coating after concrete setting, and anti-piercing through overlays anti-adhesion coating and have certain fluidity, and after waterstop was punctured, anti-piercing through overlay anti-adhesion coating and can flow voluntarily and make up; Because of after being stretched or pushing sectional area and change, anti-piercing through overlays the variation that anti-adhesion coating can adapt to sectional area voluntarily, fills up the gap or flows to other places at waterstop, makes between concrete and waterstop closed well, stops the phenomenon that seeps water.
Description of drawings
Fig. 1 pierces through the profile that overlays anti-sticking formula waterstop for the utility model is anti-;
Fig. 2 is the another kind of anti-profile that overlays anti-sticking formula waterstop that pierces through.
The specific embodiment
Below in conjunction with accompanying drawing the anti-structure that overlays anti-sticking formula waterstop that pierces through that the utility model provided is further specified.
As depicted in figs. 1 and 2; The utility model provided, and anti-piercing through overlays anti-sticking formula waterstop and comprises waterstop body 1; Overlay anti-adhesion coating 2 in spraying of the outside of waterstop body 1 or anti-the piercing through of coating; Anti-piercing through overlays anti-adhesion coating 2 and can a series of physics and chemical reaction take place with concreting, makes firm the bonding together of waterstop body and concrete; Anti-piercing through overlays anti-adhesion coating 2 after concrete setting, and anti-piercing through overlays anti-adhesion coating 2 and have certain fluidity, and after waterstop was punctured, anti-piercing through overlay anti-adhesion coating 2 and can flow voluntarily and make up; Because of after being stretched or pushing sectional area and change, anti-piercing through overlays the variation that anti-adhesion coating 2 can adapt to sectional area voluntarily, fills up the gap or flows to other places at waterstop, makes between concrete and waterstop closed well, stops the phenomenon that seeps water.
The cross sectional shape of waterstop body 1 not only is confined to two kinds of Fig. 1 and Fig. 2, also can be other arbitrary shapes.
Claims (1)
1. anti-piercing through overlays anti-sticking formula waterstop, comprises the waterstop body, it is characterized in that: be enclosed with anti-piercing through in the outside of described waterstop body and overlay anti-adhesion coating.
