Description

Technical Field

[0001] This utility model belongs to the field of building drainage riser technology, specifically relating to a suspended steel waterstop ring. Background Technology

[0002] In traditional building drainage construction, the method of pre-drilling holes, then installing pipes, and finally sealing them is typically used. However, this method has many problems, such as a tendency to leak, difficulty in ensuring the quality of the sealing, complex construction procedures, and increased construction time and costs.

[0003] To address these issues, the water-stop joint was developed. During construction, the water-stop joint is directly embedded in the floor slab, bonding tightly with the concrete to effectively prevent leakage at the pipe roots and improve waterproofing performance. Simultaneously, it simplifies construction procedures, increases efficiency, and reduces costs. Furthermore, with the continuous development of building technology and increasing demands for building quality, the performance, materials, and installation methods of water-stop joints are constantly being improved and innovated to adapt to different building structures and usage requirements.

[0004] However, existing plastic waterstops, when joined to concrete, are prone to deformation due to temperature changes because of the different coefficients of thermal expansion and contraction between the two materials, resulting in water leakage at the joint. Utility Model Content

[0005] In view of the above-mentioned problems in the prior art, the purpose of this utility model is to provide a suspended embedded steel waterstop ring, which can reduce the degree of temperature change of the waterstop section as a whole and avoid water leakage at the joint between the waterstop section and the concrete.

[0006] This utility model provides the following technical solution: a suspended embedded steel waterstop ring, including a waterstop ring body, with an upper connecting port and a lower connecting port respectively provided on both sides of the waterstop ring body, and a set of waterstop rings and waterstop structures provided on the outer side of the waterstop ring body, with an installation gap left between the waterstop structure and the outer side wall of the waterstop ring body, and a steel insert placed in the installation gap.

[0007] Furthermore, the water-stopping structure is an overall ring-shaped structure, sleeved on the outside of the water-stopping ring body, with its bottom fixedly connected to the water-stopping ring body, and an annular installation gap formed between the inner wall of the water-stopping structure and the outer wall of the water-stopping ring body.

[0008] Furthermore, the steel insert has a ring-shaped structure and is fitted into the installation gap.

[0009] Furthermore, a set of water-stopping ring structures is provided on the outer side of the water-stopping structure.

[0010] Furthermore, the water-stopping structure and the water-stopping ring body are integrally formed.

[0011] By adopting the above-mentioned technology, the beneficial effects of this utility model compared with the prior art are as follows:

[0012] This invention provides an annular water-stopping structure on the outside of the water-stopping ring body, creating an installation gap between the water-stopping structure and the water-stopping ring body. Combined with the steel insert, the steel insert is integrated with the water-stopping ring body. Utilizing the low coefficient of thermal expansion and contraction of steel, the deformation of the water-stopping ring body with temperature changes is reduced, thereby reducing water leakage at the joint between the water-stopping ring and the concrete.

[0017] Please see Figure 1-2 A suspended embedded steel waterstop ring includes a waterstop ring body, with an upper connection port 1 and a lower connection port 2 on both sides of the waterstop ring body for connecting to a pipe; a waterstop structure 3 is provided on the outer side, and a steel insert 2 is provided between the waterstop structure 3 and the outer side wall of the waterstop ring body.

[0018] Specifically, the main body of the water-stop ring is a circular tube structure, and in this embodiment, multiple water-stop ring structures are provided on its outer side.

[0019] Specifically, the water-stop structure 3 is a ring-shaped structure, which is fitted on the outside of the water-stop ring body. An annular installation gap is formed between its inner sidewall and the outer sidewall of the water-stop ring body. Its bottom end is fixedly connected to the outer sidewall of the water-stop ring body, and the two can be integrally formed. Multiple water-stop ring structures are provided on the outer sidewall of the water-stop structure 3.

[0020] Specifically, the steel insert 2 is a ring structure, the size of which matches the installation gap. It is embedded and fastened in the installation gap, so that it forms a whole with the water-stop structure 3 and the main body of the water-stop ring. By utilizing the small coefficient of thermal expansion and contraction of steel, the deformation of the overall structure with temperature changes is reduced, thereby avoiding water leakage caused by gaps between the water-stop ring and the concrete layer.
