Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of construction, and more specifically, particularly relates to a waterproof structure for an expansion joint. Background Art
[0002] Building expansion joints, also known as expansion joints, refer to a structural joint set at an appropriate position along the construction joint direction of a building or structure to prevent cracks or damage to the structure due to climate and temperature changes (thermal expansion and contraction). Expansion joints divide building components above the foundation, such as walls, floors, roofs (except wooden roofs), into two independent parts, allowing the building or structure to expand and contract horizontally along the length direction.
[0003] The existing publication number CN220580229U discloses a waterproof structure for an expansion joint. Although a sealing plate is set to enable the device to adapt to the expansion and contraction of the expansion joint, the combined action of the arc-shaped water retaining plate, the upper waterproof plate, the lower waterproof plate and the waterstop strip can provide effective waterproofing for the expansion joint. By detaching the first fixing bolt and the second fixing bolt from the wall, the fixing plate and the mounting plate can be driven upward and detached from the wall through the cross plate. At this time, the mounting plate can be slid outward to detach from the sliding bar, and the waterstop strip can be removed so that it can be replaced, thereby improving the convenience of replacing the waterstop strip.
[0004] Based on the above, the inventors discovered the following problems: However, the waterstop is suitable for the same horizontal height of the walls on both sides of the expansion joint, but the walls on both sides of the expansion joint are not all at the same horizontal height, which makes this waterproof structure not applicable. At the same time, the expansion joint is long, and the gap between the two waterproof structures after this kind of waterproof structure is spliced together is large, which makes it easy for water to seep through the gaps between the waterproof structures.
[0005] Therefore, in view of this, research and improvement are conducted on the existing structure and deficiencies, and a waterproof structure for expansion joints is provided in order to achieve a more practical purpose. Utility Model Content
[0006] In order to solve the above technical problems, the utility model provides an expansion joint waterproof structure to solve the problem that the existing walls on both sides of the expansion joint are not all located at the same horizontal height, resulting in the unsuitability of the waterproof structure.
[0007] The utility model provides a waterproof structure for expansion joints, which is achieved by the following specific technical means:
[0008] A waterproof structure for expansion joints, comprising a first cover plate and a second cover plate. The first cover plate and the second cover plate are symmetrically arranged. Sealing gaskets are fixed to the top of the inner walls and one side of the inner side walls of the first cover plate and the second cover plate. At both ends of the side of the first cover plate close to the second cover plate, third hinge seats are fixed. At both ends of the side of the second cover plate close to the first cover plate, second hinge seats are fixed. A threaded rod is hinged inside the third hinge seat. A threaded sleeve rod is movably installed inside the second hinge seat. The threaded sleeve rod is threadedly connected to the threaded rod. In the middle of the top of the outer wall of the first cover plate, a first hinge seat is fixed. In the middle of the top of the outer wall of the second cover plate, a second hinge seat is fixed. A first support rod is hinged inside the first hinge seat. A second support rod is hinged inside the second hinge seat. A water-blocking cloth is laid on the outer walls of the first support rod and the second support rod.
[0009] Further, the second hinge seat is hinged to a connecting block, the connecting block is rotatably connected to the threaded sleeve rod, and the length value of the threaded sleeve rod is equal to the length value of the threaded rod.
[0010] Further, the first hinge seat and the second hinge seat are on the same horizontal plane. A first card slot is opened on one side of the top end of the first support rod, and a second card slot is opened on the other side of the top end of the second support rod.
[0011] Further, the first card slot and the second card slot fit together. A first connecting bolt is rotatably connected through the other side of the top end of the first support rod, and a second connecting bolt is rotatably connected through one side of the second support rod. The second connecting bolt is threadedly connected to the first connecting bolt.
[0012] Further, first grooves are opened at the bottom of one end of the first cover plate and the second cover plate, and placement grooves are opened at the top of the other end of the first cover plate and the second cover plate. The first grooves and the placement grooves are used in combination.
[0013] Further, the width value of the water-blocking cloth is greater than the sum of the length values of the first support rod and the second support rod.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] 1. In the utility model, by placing the first cover plate and the second cover plate on both sides of the top of the expansion joint respectively, and connecting them through the threaded sleeve rod and the threaded rod, the distance between the two ends can be adjusted, so that the first cover plate and the second cover plate can be applied to expansion joints of different widths. By connecting the threaded sleeve rod and the threaded rod through the first hinge seat and the second hinge seat, the first cover plate and the second cover plate can be used at different horizontal heights. Subsequently, by tightening the first connecting bolt and the second connecting bolt, the first support rod and the second support rod are limited. In rainy weather, water flows along the water-blocking cloth, so as to achieve the effect of being applicable to expansion joints with different heights on both sides.
[0016] 2. In the present utility model, when encountering a relatively long expansion joint, the first groove and the placement groove can be connected, so that the connection between two adjacent first covers and between two adjacent second covers is tight, reducing the possibility of water seepage, thereby achieving the effect that the two waterproof structures are tightly connected after splicing and reducing the possibility of water seepage.

[0025] Embodiment:
[0026] As shown in Figure 1 to Figure 4 shown:
[0027] The utility model provides a waterproof structure for expansion joints, which includes a first cover plate 1 and a second cover plate 2. The first cover plate 1 and the second cover plate 2 are symmetrically arranged. Sealing gaskets 13 are fixed on the top of the inner walls and one side of the inner side walls of the first cover plate 1 and the second cover plate 2. Third hinge seats 5 are fixed at both ends of the first cover plate 1 close to the second cover plate 2. Second hinge seats 21 are fixed at both ends of the second cover plate 2 close to the first cover plate 1. A threaded rod 4 is hinged inside the third hinge seat 5. A threaded sleeve rod 3 is movably installed inside the second hinge seat 21. The threaded sleeve rod 3 is threadedly connected with the threaded rod 4. A first hinge seat 14 is fixed in the middle of the top of the outer wall of the first cover plate 1. A second hinge seat 22 is fixed in the middle of the top of the outer wall of the second cover plate 2. A first support rod 6 is hinged inside the first hinge seat 14. A second support rod 7 is hinged inside the second hinge seat 22. A water blocking cloth 10 is laid on the outer walls of the first support rod 6 and the second support rod 7.
[0028] Among them, the second hinge seat 21 is hinged with a connecting block, and the connecting block is rotatably connected with the threaded sleeve rod 3. The length value of the threaded sleeve rod 3 is equal to the length value of the threaded rod 4. Through the connection of the threaded sleeve rod 3 and the threaded rod 4, the distance between the two ends can be adjusted, so that the first cover plate 1 and the second cover plate 2 can be applicable to expansion joints of different widths. By connecting the threaded sleeve rod 3 and the threaded rod 4 through the first hinge seat 14 and the second hinge seat 21, the first cover plate 1 and the second cover plate 2 can be used at different horizontal heights.
[0029] Among them, the first hinge seat 14 and the second hinge seat 22 are located in the same vertical plane. A first card slot 61 is opened on one side of the top end of the first support rod 6, and a second card slot 71 is opened on the other side of the top end of the second support rod 7. The first support rod 6 and the second support rod 7 are connected through the first card slot 61 and the second card slot 71.
[0030] Among them, the first card slot 61 and the second card slot 71 are mutually attached. The other side of the top end of the first support rod 6 is rotatably connected through a first connecting bolt 8. One side of the second support rod 7 is rotatably connected through a second connecting bolt 9. The second connecting bolt 9 is threadedly connected with the first connecting bolt 8. After the first cover plate 1 and the second cover plate 2 are connected and placed, and the length adjustment of the threaded sleeve rod 3 sliding on the threaded rod 4 is completed, the included angle between the first support rod 6 and the second support rod 7 will automatically change for adaptation. Subsequently, by tightening the first connecting bolt 8 and the second connecting bolt 9, the first support rod 6 and the second support rod 7 are limited. After the water blocking cloth 10 is laid, the water blocking cloth 10 exerts pressure on the first support rod 6 and the second support rod 7, and then exerts pressure on the top of the first cover plate 1 and the second cover plate 2 to prevent one of the cover plates from detaching when the first cover plate 1 and the second cover plate 2 are at different horizontal heights.
[0031] Among them, first grooves 11 are provided at the bottom ends of one sides of the first cover plate 1 and the second cover plate 2, and placing grooves 12 are provided at the top ends of the other sides of the first cover plate 1 and the second cover plate 2. The first grooves 11 and the placing grooves 12 are used in a matching manner. When encountering a relatively long expansion joint, the first grooves 11 and the placing grooves 12 can be connected, so that the adjacent two first cover plates 1 and the adjacent two second cover plates 2 are closely connected, reducing the possibility of water seepage.
[0032] Among them, the width value of the water blocking cloth 10 is greater than the sum of the length values of the first support rod 6 and the second support rod 7. After the first cover plate 1 and the second cover plate 2 are placed, the length of the threaded sleeve rod 3 sliding on the threaded rod 4 is adjusted, and after the first connecting bolt 8 and the second connecting bolt 9 are tightened, the water blocking cloth 10 is laid on the tops of the first support rod 6 and the second support rod 7. In rainy weather, water flows along the water blocking cloth 10.
[0033] The specific usage method and function of this embodiment are as follows:
[0034] In the present utility model, first, the first cover plate 1 and the second cover plate 2 are respectively placed on both sides of the top of the expansion joint and are connected by the threaded sleeve rod 3 and the threaded rod 4. The distance between the two ends can be adjusted, so that the first cover plate 1 and the second cover plate 2 can be applied to expansion joints of different widths. The threaded sleeve rod 3 and the threaded rod 4 are connected through the first hinge seat 14 and the second hinge seat 21, so that the first cover plate 1 and the second cover plate 2 can be used at different horizontal heights. After the first cover plate 1 and the second cover plate 2 are connected and placed, and the length of the threaded sleeve rod 3 sliding on the threaded rod 4 is adjusted, the included angle between the first support rod 6 and the second support rod 7 will automatically change for adaptation. Subsequently, by tightening the first connecting bolt 8 and the second connecting bolt 9, the first support rod 6 and the second support rod 7 are limited. After the water blocking cloth 10 is laid, the water blocking cloth 10 exerts pressure on the first support rod 6 and the second support rod 7, and thus exerts pressure on the tops of the first cover plate 1 and the second cover plate 2, preventing one of the cover plates from detaching when the first cover plate 1 and the second cover plate 2 are at different horizontal heights. The water blocking cloth 10 is laid on the tops of the first support rod 6 and the second support rod 7. In rainy weather, water flows along the water blocking cloth 10. When encountering a relatively long expansion joint, the first grooves 11 and the placing grooves 12 can be connected, so that the adjacent two first cover plates 1 and the adjacent two second cover plates 2 are closely connected, reducing the possibility of water seepage.
