[0002] The rubber waterstop is made of natural rubber or various synthetic rubbers as the main raw materials, mixed with various additives and fillers, and is plasticized, mixed, and pressed into shape. It is used to be installed at the expansion joint to prevent water leakage at the expansion joint. The patent with application number 202120963069.X discloses a rubber waterstop, including a waterstop body, and connecting heads are respectively provided on the two side positions along the width direction of the waterstop body. The same connecting head has a first inclined surface connected to the upper side surface of the waterstop body, a second inclined surface connected to the lower side surface of the waterstop body, a third inclined surface connected to the second inclined surface, and a fourth inclined surface connected to the first inclined surface. It can fully contact with the concrete and has better waterproof ability. However, it is not easy to fix it when pouring concrete. It is easy to shift when pouring concrete, and it is difficult to ensure that the waterstop is in the correct position in the concrete. Utility Model Content

[0012] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0013] Specific implementation method: Figure 1 As shown, a rubber waterstop includes a waterstop body 2, wherein the waterstop body 2 is provided with expansion strips 4 on both sides thereof in the width direction. The expansion strips 4 increase in thickness as they are further away from the waterstop body 2. The cross-section of the expansion strips 4 is preferably an isosceles trapezoid, wherein the upper base of the isosceles trapezoid is combined with the side surface of the waterstop body 2 in the width direction, and the length of the lower base of the isosceles trapezoid is greater than the thickness of the waterstop body 2. The two waists of the isosceles trapezoid are respectively located on the upper and lower sides of the waterstop body 2. The expansion strip 4 is provided with a groove 41 on the side away from the waterstop body 2, wherein a plurality of support plates 5 are provided at intervals in the groove 41, and the support plates 5 are provided with fixing holes 51 running through both sides thereof. When in use, lead wire or iron wire can be passed through the fixing holes 51 and tied to the steel bars (the steel bars preset when pouring reinforced concrete or the additional steel bars provided to fix the waterstop) to fix the waterstop body 2, so that it is not easy to be displaced during the pouring of concrete, and it is easy to ensure that the waterstop is in the correct position in the concrete. After concrete is poured, it enters groove 41. After the concrete hardens, the upper and lower sides of expansion strip 4 cannot move closer together, resulting in a stronger anchoring ability. If groove 41 is not present, that is, expansion strip 4 is solid, the anchoring ability will not be as strong as if there is concrete in groove 41, because the rubber can be further compressed and the thickness of this area is relatively thick (the thicker the area, the greater the deformation under the same force).

[0014] The cross section of the groove 41 is an isosceles triangle, the height of which is on the symmetry plane in the thickness direction of the waterstop body 2 , so that the anchoring capabilities of the upper and lower sides of the expansion strip 4 are substantially the same.

[0015] A deformation portion 1 is provided in the middle of the width direction of the waterstop body 2, and a deformation hole 11 is provided in the center of the deformation portion 1. When the reinforced concrete on both sides of the expansion joint undergoes relative displacement within a certain range, the waterstop body 2 will not be damaged.

[0016] A plurality of waterstop bars 3 are arranged at intervals on the upper and / or lower sides of the waterstop body 2. The waterstop bars 3 enhance the anchoring ability of the waterstop body 2 in the reinforced concrete and also enhance the waterproof sealing performance between the waterstop body 2 and the reinforced concrete.

[0017] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
