Description

Technical Field

[0001] This utility model relates to the technical field of water conservancy construction, and in particular to a toe plate waterstop joint protection device. Background Technology

[0002] In the construction of rockfill dams, the first step is to construct the foundation panel dam. In order to prevent water seepage, water-stop joints are usually used for seepage prevention. These water-stop joints are typically made of rubber or copper.

[0003] When using copper waterstops, to ensure their stability, one end of the copper waterstop is installed along with the toe slab during the toe slab pouring process. This one end of the copper waterstop is placed inside the toe slab. According to the construction plan, since the pouring of the panel will be spaced out over a long period of time, the other end of the copper waterstop connected to the panel is easily subject to impacts and concrete adhesion during construction without any protective measures, which may affect the waterstop's anti-seepage effect.

[0004] In existing technologies, a protective cover is typically used to protect the exposed end of the water-stop copper sheet. To ensure stability, the upper and lower ends of the protective cover are welded to the pre-reserved anchor bars at the toe plate. The exposed end of the pre-reserved anchor bar is bent to be perpendicular to the ground, allowing the outer circumferential wall of the anchor bar to weld to the end face of the U-shaped protective cover, resulting in a large welding area and thus ensuring stable installation. However, this protective device still has some problems that need improvement during use:

[0005] The protective cover and anchor bars are connected by welding, which requires professional personnel and is time-consuming, resulting in low installation efficiency and high requirements for the installers.

[0006] After the protective cover is welded to the anchor bar, it is difficult to disassemble the protective cover later, resulting in low disassembly efficiency and damage to the protective cover, which in turn prevents the protective cover from being reused, thus increasing construction costs.

[0007] Therefore, there is an urgent need for a protective device to solve the above problems. Utility Model Content

[0008] The purpose of this utility model is to provide a toe plate water-stop joint protection device to solve the above-mentioned technical problems.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0048] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0049] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, 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, and therefore should not be construed as a limitation of this utility model.

[0050] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0051] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted.

[0052] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0053] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0054] It should be understood that during construction, the protective cover and anchor bars are connected by welding, which requires professional personnel to operate and takes a long time. This results in low installation efficiency of the protective cover and high requirements for the installers.

[0055] Furthermore, after the protective cover is welded to the anchor bar, it is difficult to disassemble the protective cover later, resulting in low disassembly efficiency and damage to the protective cover, which in turn prevents the protective cover from being reused, thus increasing construction costs.

[0056] To improve the above problems, this embodiment provides a toe plate water-stop joint protection device, which mainly includes a protective cover and a slider.

[0057] In this embodiment, the protective cover 1 adopts a U-shaped structure and has a protective space for a water-stopping copper sheet 30 inside. When the protective cover 1 is installed, the cover opening of the protective cover 1 faces the toe plate 9, and the copper sheet is set in the protective space of the protective cover 1. The upper side wall and the lower side wall of the protective cover 1 are parallel to each other. The U-shaped structure of the protective cover 1 is existing technology and will not be described in detail.

[0058] In this embodiment, as Figures 1-3 As shown, one end of the upper sidewall of the protective cover 1 is bent upward to form a convex plate 11, which is perpendicular to the upper sidewall of the protective cover 1. The lower sidewall of the protective cover 1 is bent downward to form a convex plate 11, which is perpendicular to the lower sidewall. The upper and lower sidewalls of the protective cover 1 are parallel. Specifically, one end of the upper sidewall of the protective cover 1 facing the toe plate 9 is bent upward to form a convex plate 11, and one end of the protective cover 1 facing the lower sidewall of the toe plate 9 is bent downward to form a convex plate 11. The convex plates 11 at one end of the upper and lower sidewalls are perpendicular to the upper and lower sidewalls, respectively.

[0059] The convex plate 11 has multiple sliders 2 at the end away from the protective cover 1. The sliders 2 are detachably connected to the convex plate 11 and can move back and forth along the extension direction of the boundary line between the side wall of the convex plate 11 and the upper side wall of the protective cover 1. Specifically, the sliders 2 adopt a rectangular structure and the lower surface of the sliders 2 is provided with a groove 22. The groove 22 is adapted to the convex plate 11. When the sliders 2 are set on the convex plate 11, the opposite side wall of the groove 22 is in contact with the two side walls of the convex plate 11, so that the sliders 2 can slide back and forth relative to the convex plate 11.

[0060] The device also includes multiple connecting bolts 4. The convex plate 11 has a through groove 111 that penetrates the convex plate 11 and extends along the boundary line between the side wall of the convex plate 11 and the upper side wall of the protective cover 1. The two opposite side walls of the sliding groove 22 each have multiple through holes 23, and these through holes 23 correspond one-to-one. The number of connecting bolts 4 is the same as the number of through holes 23 on one side wall of the multiple sliders 2. The through holes 23 penetrate the side wall of the slider 2 and are perpendicular to it. In this embodiment, when... When the slider 2 is installed at one end of the convex plate 11, the through holes 23 on both sides of the slider 2 are aligned with the through grooves 111 of the convex plate 11. One end of the connecting bolt 4 passes through the through holes 23 and through grooves 111 on one side wall of the slider 2 groove 22 and the through holes 23 on the other side wall of the slider 2 groove 22 in sequence, and is connected to the nut. The side of the nut and the side of the bolt head of the connecting bolt 4 abut against and fit against the side walls on both sides of the slider 2, thereby fixing the slider 2, which makes the installation and disassembly of the slider 2 relatively simple.

[0061] In this embodiment, the upper side of the slider 2 is provided with a rib groove 21. When the protective cover 1 is installed around the water-stop joint, the reserved anchor bar 7 is set in the rib groove 21, and one bent end of the anchor bar 7 abuts against the side wall of the slider 2 away from the toe plate 9. The upper end of the slider 2 is provided with a detachable end cap 3. The upper side of the outer wall of the anchor bar 7 abuts against the lower surface of the end cap 3. Specifically, the extension direction of the rib groove 21 on the upper side of the slider 2 is perpendicular to the side walls on both sides of the slider 2 and is consistent with the extension direction of the reserved anchor bar 7. One end of the reserved anchor bar 7 is bent upward and perpendicular to the upper side wall of the protective cover 1. When the protective cover 1 is connected to the reserved anchor bar 7, the reserved anchor bar 7 is installed in the rib groove 21, and the reserved anchor bar 7 is installed in the water-stop joint 1. One bent end of the anchor bar 7 is positioned on the side of the slider 2 away from the toe plate 9. Then, the end cap 3 is connected to the slider 2, ensuring that the end cap 3 covers the upper side of the rib groove 21, and the lower surface of the end cap 3 abuts against the upper side of the circumferential outer wall of the reserved anchor bar 7 in the rib groove 21. At the same time, the circumferential outer wall of the bent end of the reserved anchor bar 7 abuts against the circumferential outer wall of the end cap 3. This ensures a relatively stable connection between the protective cover 1 and the reserved anchor bar 7, while also making the installation and disassembly of the protective cover 1 and the reserved anchor bar 7 relatively simple, improving construction efficiency. Furthermore, the protective cover 1 will not be damaged during disassembly, thus allowing the protective cover 1 to be reused, thereby reducing construction costs.

[0062] In this embodiment, when installing the protective cover 1, the protective cover 1 that meets the requirements can be selected according to the length of the water-stop copper sheet 30. At the same time, the number of sliders 2 that need to be installed on the protective cover 1 is determined according to the number of reserved anchor bars 7. Then, according to the interval between the reserved adjacent reserved anchor bars 7, the sliders 2 are slid to the position on the upper end of the convex plate 11 corresponding to the reserved anchor bars 7 for installation, thereby making the application range of this device wider.

[0063] Among them, sliders 2 with different sizes of grooves 21 can be used according to the diameter of the reserved anchor bar 7, so as to be compatible with the reserved anchor bars 7 of different sizes.

[0064] In this embodiment, the end caps 3 all adopt a rectangular structure, and the lower surface of the end caps 3 is adapted to the upper surface of the slider 2. The end caps 3 are provided with bolt holes 31 and fixing bolts 5 at the four corners, and the upper surface of the slider 2 is provided with connecting holes 25 at the four corners. When the end caps 3 are placed on the slider 2, the lower surface of the end caps 3 abuts and fits against the upper surface of the slider 2, and one end of the fixing bolts 5 passes through the bolt holes 31 and connecting holes 25 in sequence and is bolted to the connecting holes 25, so that the installation and disassembly of the end caps 3 and the slider 2 are relatively simple.

[0065] In this embodiment, the end face of the convex plate 11 facing away from the water-stop section is provided with an arc-shaped limiting groove 112. The limiting groove 112 is opened along the extension direction of the boundary line between the convex plate 11 and the protective cover 1. When the protective cover 1 is installed around the water-stop copper sheet 30, the groove opening of the limiting groove 112 faces away from the water-stop joint. The side wall of the bottom of the sliding groove 22 is provided with an arc-shaped protrusion 24, which is adapted to the limiting groove 112. When the slider 2 is installed on the convex plate 11, the outer side wall of the protrusion 24 abuts and fits against the groove wall of the limiting groove 112, thereby stabilizing the displacement direction of the slider 2. It can also cooperate with the end cover 3, the reserved anchor bar 7, the side walls on both sides of the sliding groove 22 and the convex plate 11, etc., so that the installation of the slider 2 and the convex plate 11 is relatively stable.

[0066] In this embodiment, a rubber pad 6 is provided on the lower surface of the end cap 3. The rubber pad 6 is adapted to the rib groove 21. The outer walls of the opposite sides of the rubber pad 6 are in contact with the opposite side walls of the rib groove 21. When the end cap 3 is set on the slider 2, the lower end of the rubber pad 6 is inserted into the rib groove 21, and the lower surface of the rubber pad 6 abuts against the anchor bar 7, thereby further fixing the anchor bar 7, so that the installation of the anchor bar 7 is more stable.

[0067] In this embodiment, multiple clamping members 8 are provided on the upper and lower sidewalls of the protective cover 1. The multiple clamping members 8 are arranged sequentially at intervals along the extension direction of the boundary line between the convex plate 11 and the upper sidewall of the protective cover 1. The clamping member 8 includes a rotating plate 81 and a screw 82. The rotating plate 81 is provided with a rotating hole 811. The screw 82 is threadedly connected to the rotating plate 81 through the rotating hole 811. One end of the screw 82 passes through the convex plate 11 and abuts against the outer wall of the toe plate 9. The screw 82 is perpendicular to the convex plate 11 and the sidewall of the slider 2.

[0068] In this embodiment, the protruding plate 11 is provided with a plurality of screw holes 113. The plurality of screw holes 113 are arranged sequentially at intervals along the extension direction of the boundary line between the protruding plate 11 and the protective cover 1, and are adapted to the screws 82. The plurality of screws 82 are all arranged between the through groove 111 and the protective cover 1. One end of the screw 82 passes through the protruding plate 11 through the screw hole 113 and abuts against the outer wall of the toe plate 9.

[0069] In this embodiment, a top clamping plate 10 is provided at one end of the screw 82. The top clamping plate 10 adopts a cylindrical structure. When installing the protective cover 1, the reserved anchor bar 7 is first connected to the slider 2, and then the screw 82 is turned so that the top clamping plate 10 at one end of the screw 82 abuts against the toe plate 9, thereby making the circumferential side wall of the bent end of the reserved anchor bar 7 abut against the side wall of the end cover 3, thus making the installation of the protective cover 1 more stable and the disassembly more convenient.

[0070] In this embodiment, a top clamping pad 20 is provided on the side of the top clamping plate. The top clamping pad 20 is made of rubber, so that when the protective cover 1 is installed, the elasticity of the top clamping pad 20 continuously provides force to the screw 82, so that the top clamping plate 10 at one end of the screw 82 and the toe plate 9 are stable against each other. At the same time, it avoids the difference in installation accuracy caused by small deviations in the bending dimensions of the reserved anchor bar 7.
