Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-2, the embodiment provides a steel-edged rubber waterstop, which includes a waterstop body 1, wherein a deformation region 11 with a through hole is disposed in the middle of the waterstop body 1, two sides of the deformation region are respectively connected with a steel plate 2 extending outward, one side of the steel plate 2 is provided with a tensile portion 21 embedded in the waterstop body 1, and the other side is provided with a plurality of protrusions 22 arranged side by side.
When the steel-edge rubber water stop is used, the steel-edge rubber water stop is arranged at a construction joint, the bulge 22 on the steel plate 2 can be embedded into concrete, and compared with the original plane type contact, the bulge 22 forms firmer connection. The waterstop area body 1 is used for construction joint stagnant water, and when the construction joint takes place to change, because the design of tensile portion 21, the difficult appearance of steel sheet 2 breaks away from the waterstop area body 1, only has the deformation zone 11 and is elongated the attenuation, can not take place new seepage between steel sheet 2 and the waterstop area body 1 to possess good antiseep performance.
Further, in order to meet the requirement of the physical and mechanical properties of the water stop strip body 1 and ensure the reliability of water stop, in the embodiment, the water stop strip body 1 is made of chloroprene rubber material, the tensile strength is not less than 15Mpa, the elongation at break is not less than 380%, the permanent set at definite elongation is not more than 20%, the tear strength is not less than 35N/mm, and the brittleness temperature is not higher than-45 ℃.
In order to enhance the water-blocking effect, a plurality of waterproof ribs 12 are arranged between the deformation area 11 and the steel plate 2 side by side, and the waterproof ribs 12 and the water-stop strip body 1 are integrally formed. In this embodiment, the waterproof ribs 12 are also made of neoprene, and the number of the waterproof ribs is two, each waterproof rib 12 protrudes from the upper and lower surfaces of the water stop strip body 1, and after swelling in water, the waterproof ribs and concrete can form a good water stop seal, and the pressure resistance of the water stop strip body 1 can be enhanced.
As shown in FIG. 2-3, the steel sheet 2 is a galvanized sheet having a thickness of 2 to 4 mm. Reducible corruption of galvanized sheet guarantees the reliability that steel sheet 2 and concrete are connected, and in this embodiment, the galvanized sheet thickness is 3mm, and this thickness has greatly strengthened steel sheet 2's structural strength, can avoid steel sheet 2 to shift because of warping under the high pressure, and then guarantees the effect of stagnant water.
Further, the surface of the steel plate 2 is provided with anti-slip threads 23. The anti-slip lines 23 can further enhance the connection strength between the steel plate 2 and the concrete, and are easy to process and manufacture and low in cost.
Further, the protrusion 22 is provided with a through hole 24 for positioning. The perforation 24 on the protruding 22 of steel sheet 2 accessible and the steel bar structure in the concrete are connected to reinforcing steel plate 2's fixed strength avoids the problem that follow-up concrete pouring in-process steel sheet 2 shifted.
Specifically, the tensile part 21 is of an inverted hook structure or a T-shaped structure, so that a better tensile effect can be realized; the tensile part 21 is connected with the water stop belt body 1 in a vulcanization mode, wherein the connection part of the tensile part 21 and the water stop belt body 1 is in a drop shape, so that the tensile part 21 is embedded into the water stop belt body 1.
The present invention is not limited to the above specific embodiments, and for those skilled in the art, the above conception can be used without any creative work, and all the changes made fall within the protection scope of the present invention.
