Abstract
The utility model belongs to the technical field of the waterstop, a strong sealing rubber waterstop is disclosed. The main technical characteristics are as follows: the telescopic belt comprises a telescopic ring with telescopic holes, a belt body positioned on two sides of the telescopic ring and a dovetail end positioned outside the belt body, wherein a plurality of deformation holes with certain intervals are arranged at the vertical central line position of the belt body. When the construction, the concrete extrudees the area body for the area body warp because of the existence in deformation hole, and like this, the upper surface and the lower surface of the area body combine more firmly with the concrete, and sealing performance is good, and after using a period, when rubber materials because of ageing and elasticity reduces, because of the outside tension that produces in deformation hole that the extrusion warp, the faying face of the area body and concrete still can realize fine sealing, life prolongs greatly.
Description
Technical Field
The utility model belongs to the technical field of the waterstop, especially, relate to a strong sealing rubber waterstop.
Background
Rubber water stopping is needed to prevent water or other impurities from leaking at the bridge expansion joint device, the water conveying pipeline joint and the like. The rubber waterstop that uses at present is including the expansion ring that has the telescopic hole, the area body that is located this expansion ring both sides and the forked tail end that is located this area external portion, and the telescopic hole can provide certain flexible volume to the stagnant water area, and the forked tail end can play the fixed action, prevents that the waterstop from deviating from. The rubber strip can be used for sealing. The currently used rubber waterstops have the following defects: firstly, the belt body of the rubber water stop is made of rubber materials, the elasticity of the belt body made of the rubber materials is reduced along with the aging of the rubber materials, the sealing performance between the belt body and concrete is poor, water leakage and the like are caused, and the service life of the water stop is shortened; secondly, because the belt body of the rubber waterstop is made of rubber materials, the deformation of the belt body is small, the pressure between the belt body and concrete is small, and the sealing effect is poor.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a sealed effectual, long service life's strong sealing rubber waterstop.
In order to solve the above problem, the utility model discloses technical scheme that the strong sealing rubber waterstop adopted does:
the telescopic belt comprises a telescopic ring with telescopic holes, a belt body positioned on two sides of the telescopic ring and a dovetail end positioned outside the belt body, wherein a plurality of deformation holes with certain intervals are arranged at the vertical central line position of the belt body.
The additional technical characteristics are as follows:
the section of the deformation hole is circular, and the ratio of the diameter of the circle to the thickness of the belt body is 1:5-1: 3;
the section of the deformation hole is in a herringbone shape;
the section of the deformation hole is triangular;
the upper surface and the lower surface of the belt body are provided with anti-seepage strips at intervals.
The utility model provides a strong sealing rubber waterstop compares with prior art, has following advantage: firstly, because the telescopic structure comprises a telescopic ring with telescopic holes, a belt body positioned on two sides of the telescopic ring and a dovetail end positioned outside the belt body, a plurality of deformation holes with certain intervals are arranged at the vertical central line position of the belt body, and during construction, concrete extrudes the belt body to ensure that the belt body deforms due to the existence of the deformation holes, thus, the upper surface and the lower surface of the belt body are combined with the concrete more firmly, the sealing performance is good, after the rubber material is used for a period of time, when the elasticity of the rubber material is reduced due to aging, the deformation holes deformed due to extrusion generate tension outwards, the combined surface of the belt body and the concrete can still realize good sealing, and the service life is greatly prolonged; secondly, the section of the deformation hole is circular, so that the processing is more convenient, the ratio of the diameter of the circle to the thickness of the belt body is 1:5-1:3, and compared with the existing water stop belt, the tensile strength of the belt body is not reduced too much, the recovery tension is larger, and the sealing effect is good; thirdly, because the upper surface and the lower surface interval of the belt body are provided with the anti-seepage strip, the anti-seepage strip adopts the water-swelling material to make, and when water appears on the surface of the belt body, the anti-seepage strip swells with water, and the sealing effect is better.

Detailed Description
The structure and the application principle of the strong sealing rubber water stop of the present invention will be further described in detail with reference to the accompanying drawings and the specific embodiments.
As shown in fig. 1, the utility model discloses the structural schematic diagram of strong sealing rubber waterstop, the utility model discloses strong sealing rubber waterstop is including the expansion ring 2 that has telescopic hole 1, the area body 3 that is located 2 both sides of this expansion ring and the forked tail end 4 that is located 3 outsides of this area body, sets up the deformation hole 5 of a plurality of intervals certain distance in the vertical central line position of the area body 3.
When the construction, the concrete extrudees the area body for the area body warp because of the existence in deformation hole 5, and like this, the upper surface and the lower surface of the area body combine more firmly with the concrete, and sealing performance is good, and after using a period, when rubber materials because of ageing elasticity reduces, because of the outside tension that produces in deformation hole 5 that the extrusion warp, the faying face of the area body and concrete still can realize fine sealing, life prolongs greatly.
As shown in fig. 1 and 2, the section of the deformation hole 5 is circular, so that the processing is more convenient, the ratio of the diameter of the circle to the thickness of the belt body is 1:5-1:3, not only the tensile strength of the belt body is not reduced too much, but also the recovery tension is larger, and the sealing effect is good.
As shown in fig. 3, the cross-section of the deformation hole 5 may be a "herringbone".
As shown in fig. 4, the cross-section of the deformation hole 5 may be triangular.
As shown in fig. 2, 3 and 4, the impermeable strips 6 are arranged on the upper surface and the lower surface of the belt body 3 at intervals, the impermeable strips 6 are made of water-swellable material, and when water appears on the surface of the belt body, the impermeable strips swell with water, so that the sealing effect is better.
The utility model discloses a protection scope not only limits in above-mentioned embodiment, as long as the structure with the utility model discloses strong sealing rubber waterstop structure is the same or similar, just falls the utility model discloses the scope of protection.
