Description

Technical Field

[0001] This utility model relates to the field of waterstops, and in particular to an embedded rubber waterstop. Background Technology

[0002] Embedded rubber waterstops, also known as centrally placed rubber waterstops, are a type of water-prevention building material that is fixed to pre-embedded reinforcing bars and then poured into the building during concrete pouring. They are primarily used in expansion joints and other structural elements of concrete buildings, utilizing the elasticity and structure of the rubber material to accommodate the expansion and contraction of the concrete. Currently, the most commonly used embedded rubber waterstops in engineering are steel-edged waterstops, which have galvanized steel plates vulcanized and bonded to both sides of the central rubber substrate. While the galvanized steel plates facilitate the fixing of the waterstop to some extent, their flat surface results in relatively weak adhesion to the concrete. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a centrally embedded rubber waterstop. The technical solution adopted by this utility model is as follows:

[0004] This utility model provides an embedded rubber waterstop, including a central rubber substrate. Galvanized steel plates are embedded on both sides of the rubber substrate. Wire mesh is provided on the upper and lower surfaces of the galvanized steel plates along the length direction. The outer edges of the upper and lower wire mesh are connected by an arc-shaped bending section, which is integrally formed with the upper and lower wire mesh.

[0005] Preferably, the rubber matrix includes an intermediate elastomer, both sides of which are provided with extended edges, and the outer edge of the extended edges is provided with a bulging end, and the inner edge of the galvanized steel sheet is embedded in the bulging end.

[0006] Preferably, the intermediate elastomer is U-shaped, and reinforcing ribs are provided in the U-shaped opening of the intermediate elastomer.

[0007] Preferably, the reinforcing rib is X-shaped.

[0008] Preferably, the bulging end is teardrop-shaped, and the bulging end gradually decreases in size from the inside to the outside along the transverse direction.

[0009] Preferably, the inner edge of the wire mesh extends into the rubber matrix.

[0010] Preferably, a steel wire is fixed inside the arc-shaped bending section, and a gap is left between the steel wire and the outer edge of the galvanized steel plate.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0012] This invention involves covering a steel plate with a wire mesh, which increases the bonding strength between the waterstop and the concrete. At the same time, the curved bends of the wire mesh facilitate fixing with binding wire, making the installation of the waterstop easier. Attached Figure Description

[0020] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] Example 1

[0022] like Figure 1 and 2 As shown, this embodiment discloses a centrally embedded rubber waterstop, including a central rubber substrate 1, with galvanized steel plates 2 embedded on both sides of the rubber substrate 1, and the rubber substrate 1 and the galvanized steel plates 2 are bonded together by a vulcanization process.

[0023] Wire mesh 3 is welded to both the upper and lower surfaces of the galvanized steel sheet 2 along its length. The wire mesh 3 is fixed to the galvanized steel sheet 2 by electric welding and can be galvanized for corrosion protection later. The outer edges of the upper and lower wire mesh 3 are connected by an arc-shaped bending section 301, which is integrally formed with the upper and lower wire mesh 3 (i.e., the upper and lower wire mesh 3 and the arc-shaped bending section 301 are a single piece of wire mesh). By setting the wire mesh 3, the bonding strength between the upper and lower surfaces of the galvanized steel sheet 2 and the concrete can be improved.

[0024] like Figure 3 As shown, when this utility model is used, the middle part of the rubber matrix 1 is located in the middle of the deformation joint and expansion joint of the concrete building. Then, the arc-shaped bending section 301 is connected to the binding wire 5. The binding wire 5 passes through the mesh on the arc-shaped bending section 301 and is tied to the reinforcing bar.

[0025] like Figures 2 to 4 As shown, in order to improve the connection strength between the binding wire 5 and the arc-shaped bending section 301, a steel wire 4 can be fixed inside the arc-shaped bending section 301. A gap is left between the steel wire 4 and the outer edge of the galvanized steel plate 2. The binding wire 5 passes through the gap between the steel wire 4 and the galvanized steel plate 2 and is tied to the reinforcing bar.

[0026] like Figure 2 As shown, the rubber matrix 1 includes an intermediate elastomer 101. Both sides of the intermediate elastomer 101 are provided with extending edges 102. The outer edge of each extending edge 102 is provided with a bulging end 103, and the inner edge of the galvanized steel plate 2 is embedded in the bulging end 103. In this embodiment, the intermediate elastomer 101 is U-shaped, and a reinforcing rib 104 is provided in the U-shaped opening of the intermediate elastomer 101. The reinforcing rib 104 can be X-shaped.

[0027] In this embodiment, the bulging end 103 is teardrop-shaped, and the bulging end 103 gradually decreases in size from the inside to the outside along the transverse direction.

[0028] Example 2

[0029] Based on the technical solution in Embodiment 1 above, such as Figure 5 As shown, in this embodiment, the inner edge of the wire mesh 3 extends into the rubber matrix 1 to improve the connection strength between the steel plate and the rubber matrix 1.

[0030] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
