Description

Technical Field

[0001] This utility model relates to the field of building construction technology, especially tunnel construction, and specifically to a waterstop positioning device. Background Technology

[0002] In the field of tunnel construction technology, the construction quality of waterproofing and drainage systems has always been a key indicator for evaluating the overall performance of the project, especially waterproofing, which involves the installation of waterstops. Waterstops are a material used in building engineering to prevent water leakage, and are usually used in joints, expansion joints, construction joints and other parts of concrete structures.

[0003] Traditional waterstop installation typically involves simply tying it to reinforcing bars. However, during concrete pouring, the deformation of the reinforcing bars often causes the waterstop to shift, affecting its sealing performance and potentially threatening the overall structural safety of the tunnel. Furthermore, some devices use hinged joints and pressure plates to tighten the waterstop. When dealing with longer sections of waterstop, ensuring secure tightening is often difficult, leading to the waterstop loosening.

[0004] To address the aforementioned technical problems, Chinese utility model patent application number 2021204149010 discloses a waterstop positioning device for tunnels, comprising a mounting base and an electric push rod. One end of the electric push rod is fixedly mounted on the mounting base, and the other end is fixedly mounted on a lining trolley. A support frame is mounted in the mounting base with adjustable height. An electromagnet is mounted above the support frame, and a lead screw motor is mounted on the support frame. A pressure plate rotates on the lead screw of the lead screw motor, and a suction block corresponding to the position of the electromagnet is located below the pressure plate. A pressure sensor is located at the end of the support frame away from the electromagnet, and a pressing assembly for pressing the pressure sensor is mounted on the pressure plate. The pressure sensor is electrically connected to the lead screw motor. This waterstop positioning device utilizes the suction effect of the electromagnet to achieve rapid pressing and positioning of the waterstop. However, in practical applications, the tunnel environment often has the problem of moisture leakage, and the normal operation of the electromagnet requires a stable power supply. This poses certain safety hazards when the device is used in a humid environment, which limits its widespread application and practicality in actual engineering projects, and affects the promotion and application of the above-mentioned waterstop positioning device in the field of tunnel construction technology.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0021] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] Example: Figures 1 to 3 As shown, the waterstop positioning device in this embodiment mainly consists of a mounting base plate 1, clamping blocks 2, and locking components 3. To facilitate the installation of the clamping blocks 2 and provide sliding space, the mounting base plate 1 has a sliding groove 1-1. The sliding groove 1-1 extends inwards to both sides of the mounting base plate 1 to form mounting cavities 1-2 for the clamping blocks 2 to be installed. The clamping blocks 2 can move within the mounting cavities 1-2. The shape and size of the mounting cavities 1-2 are adapted to the clamping blocks 2 to ensure smooth sliding within the mounting cavities 1-2, facilitating subsequent adjustment of the clamping block 2's position. To clamp the waterstop and ensure its stability during installation and use, the clamping blocks 2 in this embodiment are a pair. The pair of clamping blocks 2 are respectively installed in two mounting cavities 1-2 and can move relative to each other to adjust the distance between the two clamping blocks 2. The distance between the clamping blocks 2 can be adjusted according to the size of the waterstop. When the waterstop is placed between the two clamping blocks 2, the clamping blocks 2 can be moved to fit tightly against the waterstop, thereby fixing the waterstop. After the spacing of the clamping blocks 2 is adjusted to match the waterstop, the mounting base plate 1 and the clamping blocks 2 are fixedly connected together by the locking assembly 3 to prevent the clamping blocks 2 from moving during construction, thus ensuring the stable positioning of the waterstop.

[0024] To simplify the structure while meeting performance requirements, the clamping block 2 in this embodiment is L-shaped. Specifically, it consists of a moving part 2-1 and a clamping part 2-2. The moving part 2-1 is installed in the mounting cavity 1-2, and its shape and size are adapted to the shape and size of the mounting cavity 1-2, allowing it to move towards the sliding groove 1-1 within the mounting cavity 1-2. The clamping part 2-2 is formed at one end of the moving part 2-1 and is perpendicular to it. By setting the clamping part 2-2, the contact area between the clamping block 2 and the waterstop is increased, thereby ensuring the stability of the waterstop during installation and use. To improve the overall structural strength of the clamping block 2 and enable it to withstand greater clamping force and external forces, the moving part 2-1 and the clamping part 2-2 are integrally formed in this embodiment. The integrally formed structure reduces connection points and avoids clamping failure caused by loose or damaged connection parts, making the clamping block 2 more reliable during use and better able to position the waterstop.

[0025] To make the movement of the clamping block 2 within the mounting cavity 1-2 more precise, in this embodiment, a positioning tooth 2-3 is formed at the bottom of the moving part 2-1. There are multiple positioning teeth 2-3, and a limiting groove 2-4 is formed between two adjacent positioning teeth 2-3. The locking component 3 is partially located within the limiting groove 2-4 to ensure that the clamping block 2 can be accurately fixed in the appropriate position after being adjusted. This arrangement avoids the problem of inaccurate positioning of the waterstop due to slight movement of the clamping block 2 after locking.

[0026] In this embodiment, an anti-slip pad 4 is also provided on the surface of the clamping block 2, specifically on the clamping surface of the clamping part 2-2. The anti-slip pad 4 significantly increases the friction between the clamping part 2-2 and the waterstop, thereby enhancing the clamping force and effectively preventing the waterstop from sliding during clamping, ensuring its stable position during construction. The anti-slip pad 4 also prevents the clamping part 2-2 from directly contacting the waterstop, thus avoiding scratches or damage to the surface of the waterstop. The anti-slip pad 4 also acts as a buffer and protector, reducing the direct pressure of the clamping block 2 on the waterstop and preventing damage to the waterstop during clamping. The anti-slip pad 4 is made of rubber, which has a high coefficient of friction, significantly increasing the friction between the clamping part 2-2 and the waterstop, effectively preventing the waterstop from sliding during clamping and ensuring its stable position during construction. The rubber material also has a certain degree of elasticity, allowing it to adapt to waterstops of different thicknesses and providing a more stable clamping effect. Even if the thickness of the waterstop is uneven, the rubber anti-slip pad 4 can ensure good contact between the clamping part 2-2 and the waterstop, thereby ensuring the stability of the waterstop.

[0027] In this embodiment, the locking assembly 3 mainly consists of a locking rod 3-1, a locking slider 3-2, a locking positioning block 3-3, and an elastic element 3-4. The locking rod 3-1 passes through the locking slider 3-2 and the locking positioning block 3-3, and the end of the locking rod 3-1 is used to be embedded in the limiting slot 2-4. The elastic element 3-4 is fitted outside the locking rod 3-1 and is located between the locking slider 3-2 and the locking positioning block 3-3. By embedding the end of the locking rod 3-1 in the limiting slot 2-4, a quick connection between the mounting base plate 1 and the clamping block 2 can be achieved, improving installation efficiency and accurately fixing the position of the clamping block 2 to prevent the clamping block 2 from shifting during construction. In this embodiment, the elastic element 3-4 is a highly economical and practical spring, mainly providing elastic buffering and automatic reset functions for the locking rod 3-1. When the position of the clamping block 2 needs to be adjusted, the locking rod 3-1 is pulled down to separate the mounting base plate 1 from the clamping block 2. When the clamping block 2 moves to the desired position, the locking rod 3-1 is released, and the locking rod 3-1 will quickly be embedded in the limiting slot 2-4 under the action of the elastic element 3-4, i.e., the spring, thus achieving a fixed connection between the mounting base plate 1 and the clamping block 2. The locking rod 3-1 and the locking slider 3-2 are fixedly connected as one unit. The locking positioning block 3-3 has a through hole for the locking rod 3-1 to pass through. That is, when the locking rod 3-1 moves down, the locking slider 3-2 moves down with the locking rod 3-1, while the locking positioning block 3-3 remains stationary. To facilitate installation and reduce installation difficulty, this embodiment also provides a limiting groove 1-3 for the locking slider 3-2 to slide within the mounting base plate 1. The locking slider 3-2 can slide up and down within the limiting groove 1-3. To prevent the locking positioning block 3-3 from protruding from the surface of the mounting base plate 1, this embodiment also provides a positioning block mounting groove 1-4 for the locking positioning block 3-3 to be installed within the mounting groove 1-4 and connected to the mounting base plate 1 via a connector 3-6. The connector 3-6 can be a connecting screw or a connecting bolt, etc.

[0028] In this embodiment, a pull ring 3-5 is also provided at the end of the locking rod 3-1, specifically as the operating end. The pull ring 3-5 provides a convenient gripping point for the operator, allowing the operator to easily pull the locking rod 3-1 by hand, greatly improving the convenience of operation, especially when frequent locking and unlocking of the clamping block 2 is required. The pull ring 3-5 also allows the operator to complete the locking and unlocking operations without the use of additional tools, reducing reliance on tools and improving work efficiency.

[0029] In this embodiment, a connection hole 5 can also be provided at the top or near the top of the mounting base plate 1. By inserting steel bars or other connectors into the connection hole 5, multiple waterstop positioning devices can be connected together to form a more stable positioning system to meet the needs of waterstops in different scenarios.

[0030] The specific installation steps of the waterstop positioning device in this embodiment are as follows: First, the clamping block 2 is installed into the mounting cavity 1-2 of the mounting base plate 1; then, the waterstop is placed between the two clamping blocks 2, and the spacing between them is adjusted by moving the clamping blocks 2 until the spacing matches the thickness of the waterstop; finally, after the spacing of the clamping blocks 2 is adjusted, the mounting base plate 1 and the clamping blocks 2 are connected and fixed using the locking assembly 3, so that the clamping blocks 2 and the mounting base plate 1 are tightly connected, thereby firmly fixing the waterstop between the clamping blocks 2.

[0031] This embodiment provides a waterstop positioning device with a simple and ingenious structure and convenient installation. It consists of a mounting base plate 1, clamping blocks 2, and a locking assembly 3. The mounting base plate 1 has mounting cavities 1-2 for mounting the clamping blocks 2. A mounting position for the waterstop is formed between a pair of clamping blocks 2. The size of the mounting position can be adjusted by adjusting the position of the clamping blocks 2 to accommodate waterstops of different thicknesses, thus making the overall utilization rate of the waterstop positioning device wider. After the clamping blocks 2 are moved to the required position to meet the installation of the waterstop, the locking assembly 3 locks the clamping blocks 2 to prevent them from shifting during use.

[0032] The waterstop positioning device in the above embodiments not only improves the accuracy and stability of waterstop installation, but also simplifies the operation process and improves work efficiency, and has significant practical value for waterproofing construction in tunnels and other projects.
