Abstract
Description
technical field
[0001] The invention relates to a water-stop belt for water sealing, in particular to a veneer type multi-flange water-stop belt. Background technique
[0002] Waterstop is a building structure material used to connect the joints of concrete structures in water conservancy and hydropower projects. At present, the copper sheet waterstop and rubber waterstop used in water conservancy and hydropower projects have only one flange on each side. In order to achieve a certain water-stop effect, the width of the flange is generally greater than the thickness of the reinforced concrete protective layer. Therefore, When arranging the steel bars of the concrete structure, in order to avoid the waterstop, the steel bars of the concrete structure have to be bent inwards, which weakens the strength of the reinforced concrete structure, and also causes great interference to the design and construction of the reinforced concrete structure. Contents of the invention [000...
Examples
Embodiment 1
[0012] Such as figure 1 As shown, the veneer-type multi-flange waterstop of the present invention includes a waterstop body made of rubber material, the section shape of the waterstop body is a U-shaped structure, and the waterstop body is located The U-shaped opening of the body is provided with a rubber connecting diaphragm 1; the left veneer 2 and the right veneer 3 of the waterstop body are respectively provided with a left wing plate 4 and a right wing extending horizontally to both sides along the longitudinal direction of the waterstop body. Plate 5, the left and right wing plates 4, 5 are three layers arranged at intervals up and down respectively, and the outer edges of each layer of left and right wing plates 4, 5 are respectively downward vertically bent flanging structures 6, 7. The radius of the semicircular connecting section 8 at the lower end of the U-shaped waterstop body is adjusted according to the width of the concrete structure joint; the width of each lef...
Embodiment 2
[0014] Such as figure 2 As shown, the veneer-type multi-flange waterstop of the present invention includes a waterstop body made of copper material, and the cross-sectional shape of the waterstop body is a U-shaped structure, located at The U-shaped opening of the waterstop body is provided with a copper connection diaphragm 9; the left veneer 10 and the right veneer 11 of the waterstop body are respectively provided with horizontally extending to both sides along the longitudinal direction of the waterstop body. Left wing plate 12 and right wing plate 13, said left and right wing plates 12, 13 are three layers arranged at intervals up and down respectively, and the upper and lower plates of each layer of left and right wing plates 12, 13 are spaced vertically along the waterstop body Ribs 14, 15 are provided. The radius of the semicircular connecting section 16 at the lower end of the U-shaped waterstop body is adjusted according to the width of the concrete structure joint...
