[0002] Embedded waterstops are commonly used in expansion joints, construction joints, and other water-stopping structures. By increasing the contact area with the concrete through the water-stopping ribs at the longitudinal center of the embedded waterstop, it can prevent water leakage and ensure the normal use of the engineering structure in a watery environment.

[0028] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0029] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer" used in the description of specific embodiments of this utility model to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0031] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0032] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0033] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0034] Example 1

[0035] like Figures 1-8As shown, a fixing mechanism for an embedded waterstop includes an abutment mechanism 100. The abutment mechanism 100 includes a main rod 1 and an abutment part 2. The abutment part 2 is disposed at one end of the main rod 1. The abutment part 2 is provided with a limiting groove 3 and an abutment surface 21. The abutment surface 21 is perpendicular to the axial direction of the main rod 1. The limiting groove 3 is located on the extension line of the main rod 1.

[0036] The abutting part 2 is used to abut against the wide side of the embedded waterstop 6. When the two abutting mechanisms 100 abut against the two sides of the embedded waterstop 6 respectively, the position of the embedded waterstop 6 can be fixed.

[0037] In optional implementations, such as Figure 1 , Figures 3-5 As shown, the abutment part 2 may include two limiting rods 22. The limiting rods 22 extend to both sides from the end of the main rod 1, so that the two limiting rods 22 are symmetrically distributed relative to the main rod 1. A limiting groove 3 is formed between the two symmetrically arranged limiting rods 22. An abutment surface 21 is provided on the side wall of the limiting rod 22, so that the abutment surface 21 can abut against the wide side of the embedded waterstop 6.

[0038] In optional implementations, such as Figure 2 As shown, the limiting rods 22 can also be an even number of four or six, and the even number of limiting rods 22 are symmetrically distributed.

[0039] In an optional embodiment, the limiting rods 22 can be an odd number of three or five, with the odd number of limiting rods 22 distributed on both sides of the main rod 1, forming a limiting groove 3 on the extension line of the main rod 1.

[0040] In optional implementations, such as Figure 1 , Figure 3 As shown, the limiting rod 22 can be an arc-shaped rod-shaped structural component, and the abutting surface 21 can be an arc-shaped surface provided on the outer side of the arc-shaped rod-shaped structural component's bend. Alternatively, the abutting surface 21 can be a flat surface formed by cutting and grinding on the outer side of the arc-shaped rod-shaped structural component's bend.

[0041] In optional implementations, such as Figure 4 , Figure 5 As shown, the limiting rod 22 can be composed of a first straight rod segment 221, an arc-shaped rod segment 222, and a second straight rod segment 223. The first straight rod segment 221 and the second straight rod segment 223 are perpendicular to each other. The first straight rod segment 221 and the second straight rod segment 223 are connected by the arc-shaped rod segment 222. The abutment surface 21 is provided on the side wall of the second straight rod segment 223. The abutment surface 21 can be a plane formed by cutting and grinding the side wall of the second straight rod segment 223, or it can be formed by the side wall of the second straight rod segment 223 itself.

[0042] In an optional embodiment, the main rod 1 can be a steel reinforcement component, the limiting rod 22 can be a steel reinforcement component, the main rod 1 and the limiting rod 22 can be welded together, or they can be an integrally formed structural component made of a single steel reinforcement component.

[0043] In an optional embodiment, adjacent first straight rod segments 221 can be arranged side by side and welded together to form an abutment portion 2, so that the abutment portion 2 has a stable structure and can cooperate with the central waterstop rib of the embedded waterstop 6 through the limiting groove 3.

[0044] In optional implementations, such as Figure 4 As shown, the second straight rod segment 223 can be surrounded by a protruding rib 4. The protruding rib 4 can be used to increase the contact stability between the limiting rod 22 and the embedded waterstop 6, and improve the limiting and fixing effect of the embedded waterstop 6.

[0045] In an optional embodiment, the protruding rib 4 can be a rib structure that is inherent in the second straight rod segment 223 itself, or it can be a rib structure formed by welding. The part of the protruding rib 4 that contacts the embedded waterstop 6 can be ground into an arc surface to avoid damage to the embedded waterstop 6 by the contact part 2.

[0046] In one or more implementations, such as Figure 5 As shown, the abutment mechanism 100 may include at least two main rods 1, each main rod 1 having a limiting rod 22 at its end. Adjacent main rods 1 are parallel and welded together, meaning the number of main rods 1 can be the same as the number of limiting rods 22, and multiple main rods 1 are parallel and welded together as a whole.

[0047] In one or more implementations, such as Figure 6 As shown, a limiting sleeve 5 can be provided at one end of the abutment part 2 near the main rod 1, and the main rod 1 and the limiting sleeve 5 are connected in a limiting manner.

[0048] In an optional embodiment, the limiting sleeve 5 may be provided with an internal thread, and the main rod 1 may be threadedly connected to the limiting sleeve 5, so that the limiting sleeve 5 and the main rod 1 can be rotated relative to each other according to the actual situation, thereby realizing the adjustment of the overall length of the fixing mechanism.

[0049] This embodiment describes a fixing mechanism for an embedded waterstop. When in use, as follows: Figure 7 , Figure 8 As shown, multiple abutment mechanisms 100 are arranged at intervals, and every two abutment mechanisms 100 abut against each other on the two wide sides of the embedded waterstop 6, so that every two abutment mechanisms 100 abut against each other from both sides of the embedded waterstop 6, restricting the position of the embedded waterstop 6. The embedded waterstop 6 can be limited and fixed by connecting the main rod 1 with the adjacent steel cage, frame and other fixed structures.

[0050] In an optional embodiment, the length of the main rod 1 of each abutment mechanism 100 can be adjusted and preset according to the actual situation to ensure that the main rod 1 can extend to the corresponding position of the nearest fixed structure such as a steel cage or frame that can be used for connection and fixation.

[0051] The fixing mechanism of the embedded waterstop in this embodiment achieves the limiting and fixing of the embedded waterstop 6 by abutting the abutting mechanism 100. The abutting mechanism 100 will not pass through or damage the embedded waterstop 6, and is not easy to damage the embedded waterstop 6, thereby affecting the waterproof effect. The structure is simple and easy to use. At the same time, the limiting groove 3 can cooperate with the middle waterstop rib of the embedded waterstop 6, and the abutting surface 21 can abut with the wide side of the embedded waterstop 6, so as to achieve stable limiting and fixing of the embedded waterstop 6.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
