Abstract
The utility model belongs to waterstop technical field, particularly relates to a kind of water-swellable composite waterstop.Rubber belt body both sides are provided with steel plate, in the middle part of rubber belt body, arranged outside has water expandable waterstop simultaneously, this water expandable waterstop and rubber strip bluk recombination are connected as a single entity, water expandable waterstop material is polyurethane material, water expandable waterstop is single or double, be at least more than one or more than a pair, its cross section is trapezoidal.This water-swellable composite waterstop, meets self-expansion after water, adds the tight ness rating of waterstop and construction of structures, thus improve sealing, water resistance, solve long-standing problem people around leakage problems, there is antiseep, anti-pull-out, anti-aging effect.
Description
Technical field
The utility model belongs to waterstop technical field, particularly relates to a kind of water-swellable composite waterstop.
Background technology
The engineering fields such as the lining cutting seam of tunnel, subway, water delivery aqueduct, reservoir, gate, checkdam, water channel, building lot, basement and other structure and building and the distortion of settlement joint, waterproof and damping, buffering, need to use waterstop.The waterstop of current use is generally General Purpose Rubber waterstop, rubber watertight strip etc.In practical engineering application, easily there is following problem in above-mentioned waterstop: concrete and rubber adhesion poor, and rubber is soft elastomer, makes concrete when building not easily by tamping, so that produces around leakage problems when head pressure is higher; Concrete joint is sewn on expansion, avulse, reverse, large deformation situation occurs under, because the elasticity of waterstop rubber water-proof stalk is large, and poor rigidity, make waterstop very easily occur loosening, coming off, be even drawn out; Steel limit waterstop, as occurred around seepage, makes steel limit that corrosion occur, has a strong impact on product application life.
Utility model content
The technical problems to be solved in the utility model is just to provide a kind of water-swellable composite waterstop, and sealing rod adopts water-expandable polyurethane material to make, and meets water self-expansion, and make it contact with construction of structures tightr, waterproof effect is better.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of water-swellable composite waterstop, rubber belt body both sides are provided with steel plate, in the middle part of rubber belt body, arranged outside has water expandable waterstop simultaneously, and this water expandable waterstop and rubber strip bluk recombination are connected as a single entity, and water expandable waterstop material is polyurethane material.
Described water expandable waterstop is single or double, is at least more than one or more than a pair, and its cross section is trapezoidal.
A kind of water-swellable composite waterstop provided by the utility model, self-expansion after chance water, adds the tight ness rating of waterstop and construction of structures, thus improves sealing, water resistance, solve long-standing problem people around leakage problems, there is antiseep, anti-pull-out, anti-aging effect.

Detailed description of the invention
Be described further below in conjunction with the structure of accompanying drawing to the preferred embodiment of a kind of water-swellable composite waterstop provided by the utility model.
As shown in Figure 1,2,3, 4, a kind of water-swellable composite waterstop of the utility model comprises rubber belt body 1, rubber belt body 1 has centre bore, the both sides of rubber belt body 1 are provided with the steel plate 2 that sulfuration with it connects as one, in the middle part of rubber belt body 1, namely central hole location arranged outside has water expandable waterstop 3.
A kind of water-swellable composite waterstop provided by the utility model, waterstop middle part still adopts elastomeric material to form, and rubber belt body 1 is for adapting to seam distortion, the both sides of rubber belt body 1 are provided with galvanized steel plain sheet 2, galvanized steel plain sheet 2 inserts the inside of rubber belt body 1, both are integrated in sulfuration, galvanized steel plain sheet 2 upper and lower surface covers butyl caulk compound overcoat, in the middle part of rubber belt body, arranged outside has water expandable waterstop simultaneously, this water expandable waterstop and rubber belt body are by extruding, sizing, compound, high temperature is connected as a single entity, water expandable waterstop is single or double, be at least more than one or more than a pair, its cross section is trapezoidal, sealing rod height and rubber strip height match, water expandable waterstop material is polyurethane material.In use, rubber belt body 1 effectively can adapt to the various distortion of seam to water-swellable composite waterstop provided by the utility model, and rubber belt body 1 has through hole, and its retractility is good; Butyl caulk compound overcoat has good tightness, water proofing property, ageing resistance, and itself and galvanized steel plain sheet 2 and concrete all have good adhesiveness, play airtight sealing, Effective Anti seepage, prevent galvanized steel plain sheet 2 by action of rust; Galvanized steel plain sheet 2 is compared rubber belt body 1 and is had higher tension, compressive strength; Water expandable waterstop 3 meets self-expansion after water, adds the tight ness rating of waterstop and construction of structures, thus improves sealing, water resistance, solve long-standing problem people around leakage problems, there is antiseep, anti-pull-out, anti-aging effect.
Water-swellable composite waterstop provided by the utility model is not limited to said structure, but no matter is which kind of form, as long as arranged outside has water expandable waterstop in the middle part of rubber belt body, all falls into protection domain of the present utility model.
