[0002] The rubber waterstop takes natural rubber and various synthetic rubbers as the main raw materials, adds various auxiliaries and fillers, and is formed by plasticating, mixing and pressing; it is mainly used in infrastructure projects, underground facilities, tunnels, sewage treatment plants, water conservancy, subways and other projects. There are some expansion joints, construction joints or deformation joints in these buildings. And in these construction projects, the groundwater will have obvious contact with the buildings. In order to prevent the groundwater from entering the building interior through the gaps such as expansion joints, construction joints or deformation joints, a waterproof barrier is set to ensure the service life of the engineering building
[0003] The rubber waterstop is processed from rubber. Due to the problems of the rubber's own characteristics, during the installation and construction process of the waterstop, due to the self - gravity of the waterstop and the flow and vibration of the concrete, problems such as the edge of the waterstop sagging, deforming and shifting will occur, reducing the anchoring performance of the waterstop in the concrete and the waterproof performance. The most serious is that after the waterstop is shifted, the concrete at the joint edge becomes thinner, and it is extremely easy to cause the concrete to fall off during tunnel settlement or earthquake, seriously affecting the driving safety and the waterproof effect of the waterstop. The commonly used fixing methods in the existing waterstop installation process are: fixing with cross - bar steel bars; fixing with special fixtures; fixing with wire and formwork, etc. The fixing bracket needs to be bent and processed, consuming materials and increasing the labor hours; and there are strict dimensional requirements for the distance between the formwork trolley and the half - stop steel formwork, and precise positioning is required during installation, and its installation process is relatively complex

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] See Figure 1 and 3 , the embodiments of the present utility model disclose a reinforced composite rubber waterstop, including: a waterstop body 1 and a reinforcement layer 2.
[0026] Wherein, anchoring ribs 3 are arranged on both the upper surface and the lower surface of the waterstop body 1. The anchoring ribs 3 are integrally formed with the waterstop body 1.
[0027] The reinforcement layer 2 is arranged inside the water stop body 1. The water stop body 1 wraps the reinforcement layer 2 inside the water stop body 1, and the reinforcement layer 2 extends a certain preset length from the end of the water stop body 1 in the width direction of the water stop body 1. The part of the reinforcement layer 2 extending out of the water stop body 1 is the anchorage area 4.
[0028] It should be noted that the reinforcement layer 2 is arranged throughout in the length direction of the water stop body 1. However, the reinforcement layer 2 can be arranged as a whole block or a structure composed of multiple blocks spliced in sequence along the length direction of the water stop body 1. The reinforcement layer 2 extends 20 - 50 mm out of the edge of the water stop body 1 along the width direction of the water stop body 1. The reinforcement layer 2 is made of metal sheet, polymer sheet, high-strength fiber board or metal wire braiding. Preferably, the reinforcement layer 2 is made of metal wire braiding. The metal wire is preferably iron wire or stainless steel wire. Specifically, the metal wire used for the reinforcement layer 2 is made of wire with a diameter of 1 mm after braiding, and the mesh holes are regular rhombus after braiding. In some other embodiments, other materials that can be vulcanized with rubber and have certain strength and toughness can be used to replace the metal wire, not limited to metals, polymer materials, etc. By arranging the reinforcement layer 2 inside the water stop body 1, the stiffness of the water stop in the width direction can be provided for the water stop. Multiple reinforcement layers 2 are arranged inside the water stop body 1, and the reinforcement layer 2 extends 20 - 50 mm outside the water stop body 1 along the width direction of the water stop body 1. The reinforcement layer 2 adopts the metal wire braiding process, which ensures the transverse stiffness of the water stop body 1 and is convenient for curling the water stop, facilitating the storage and transportation of the water stop. When used in construction joints, the reinforcement layer 2 can provide a good transverse support effect for the water stop. The setting of the anchorage area 4 can integrate the water stop with the concrete. When large gaps are generated in the tunnel concrete due to thermal expansion and contraction, settlement or geological disasters, it can effectively prevent the water stop from being pulled out due to tunnel deformation, effectively strengthening the anchorage ability of the water stop. For the reinforcement layer 2 made of metal wire braiding, the spacing between the metal wires is controllable, and the transverse stiffness can be adjusted by changing the spacing between the metal wires, so as to meet the construction requirements of the tunnel. The arrangement of the reinforcement layer 2 can effectively prevent the offset caused by the rubber characteristics of the water stop body 1 and the impact of concrete during the construction process, thereby improving the anchorage ability and waterproof ability of the water stop; the setting of the anchorage area 4 enables the water stop to be fully combined with the concrete, which can effectively enhance the anchorage ability of the water stop and prevent the water stop from being pulled out during tunnel deformation, resulting in the failure of the water stop.
[0029] In some embodiments, the anchorage ribs 3 on the upper surface of the water stop body 1 and the anchorage ribs 3 on the lower surface of the water stop body 1 are symmetric structures. Thus, when the anchorage ribs 3 are anchored with the concrete, the forces on the upper and lower sides of the water stop body 1 are balanced.
[0030] In some embodiments, anchoring ribs 3 are respectively provided at the end portions of the waterstop body 1 in its width direction, and the anchoring ribs 3 at both ends of the waterstop body 1 in the width direction are of a dovetail structure. By setting the anchoring ribs 3 of the waterstop body 1 in the width direction into a dovetail structure, the contact area between the anchoring ribs 3 and the concrete is increased through the inclined sides, thereby enhancing the anchoring ability of the anchoring ribs 3.
[0031] In some embodiments, the strengthening layer 2 is arranged at the middle position of the waterstop body 1 in the thickness direction. With such an arrangement, the structures of the waterstop body 1 on the upper surface and the lower surface of the strengthening layer 2 are the same, ensuring that the anchoring abilities of the upper and lower surfaces of the waterstop are consistent during the use of the waterstop.
[0032] In some embodiments, a plurality of anchoring ribs 3 are arranged at intervals along the width direction of the waterstop body 1. In this embodiment, four anchoring ribs 3 with a rectangular cross-section are further arranged between the dovetail-shaped anchoring ribs 3 at both ends of the waterstop body 1. In other embodiments, the number of the anchoring ribs 3 arranged between the two dovetail-shaped anchoring ribs 3 can be specifically set according to actual requirements.
[0033] In some embodiments, the waterstop body 1 is an axisymmetric structure in its width direction. This ensures that the two parts of the waterstop symmetric along the central axis in its width direction are evenly stressed.
[0034] See Figure 2 , in some embodiments, a deformation zone 5 is arranged at the middle position of the waterstop body 1 in its width direction. The deformation zone 5 has a through cavity 6 along the length direction of the waterstop, and the strengthening layer 2 is located above or below the through cavity 6. That is to say, the deformation zone 5 is a cylindrical structure arranged along the length direction of the waterstop body 1, and a through cavity 6 is arranged on the axis of the cylindrical structure. The shape of the deformation zone 5 perpendicular to the axial section is an annular structure, and the outer diameter of the annular structure is greater than the thickness of the waterstop body 1. With such an arrangement, during the use of the deformation joint, the strengthening layer 2 can meet the deformation requirements of the deformation joint while having a lateral support effect. In the waterstop for the deformation joint, the deformation zone 5 at the middle part of the strengthening layer 2 adapts to the deformation of the deformation joint, and the mesh structure of the strengthening layer 2 can also effectively adapt to the deformation effect of the deformation joint in the deformation joint.
[0035] In some embodiments, the upper surface and the lower surface of the deformation zone 5 are respectively flush with the end portions of the anchoring ribs 3 on the upper surface and the lower surface of the waterstop body 1. That is, the deformation zone 5 is respectively set into a planar structure at the top and bottom of the waterstop body 1, so that the height of the deformation zone 5 is the same as that of the anchoring ribs 3, which is convenient for anchoring the anchoring ribs 3 and the deformation zone 5 in the concrete during the construction process.

Each embodiment focuses on the differences from other embodiments, and the same or similar parts among the embodiments can be referred to each other. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the description in the method section.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
