Description

Technical Field

[0001] This utility model relates to the field of expansion joints, and in particular to an expansion joint with high strength and long service life. Background Technology

[0002] An expansion joint is a structural joint installed at an appropriate location along the construction joint direction of a building or structure to prevent cracks or damage to building components due to changes in climate and temperature. An expansion joint divides a building component above the foundation, such as a wall, floor slab, or roof, into two independent parts, allowing the building or structure to expand and contract horizontally along its length.

[0003] Existing high-strength, long-life expansion joints are usually constructed using cement pouring. However, over time, cracks can easily appear at the cement pouring points, leading to detachment and damage, resulting in unsatisfactory performance.

[0004] In view of this, this paper studies and improves the existing problems to provide a high-strength and long-lasting expansion joint. It features a first positioning plate, a second positioning plate, and an L-shaped plate that cooperate with each other and are fixedly installed in a groove on the surface of the beam by positioning bolts. This results in good structural support stability, long service life, and easy disassembly and replacement when damage occurs. It can effectively improve vehicle driving safety. The aim of this technology is to solve the problem and improve its practical value. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and 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; the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In addition, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] Reference Figure 1-3 An embodiment of this utility model provides a high-strength and long-life expansion joint, including a beam body 1. The upper surfaces of the two beam bodies 1 are provided with slots 2. A first positioning plate 3 is provided above the slots 2. A second positioning plate 4 is provided above the first positioning plate 3. An L-shaped plate 5 is fixedly provided on the bottom surface of the second positioning plate 4. The first positioning plate 3 is snapped into the interior of the L-shaped plate 5. A positioning bolt 11 is provided through the surface of the second positioning plate 4.

[0024] Specifically, the L-shaped plate 5 and the second positioning plate 4 are welded together. The end face of the second positioning plate 4 is set as a rack shape, and the surface of the second positioning plate 4 is provided with anti-slip texture 12, which makes the connection between the L-shaped plate 5 and the second positioning plate 4 more stable and can fix the first positioning plate 3 and the second positioning plate 4. At the same time, the rack shape of the end face of the second positioning plate 4 and the anti-slip texture 12 on the surface can improve the safety of vehicles traveling on the bridge surface.

[0025] Specifically, a protrusion 9 is fixedly provided on the upper surface of the first positioning plate 3, and a positioning groove 10 is provided through the surface of the second positioning plate 4, with the protrusion 9 installed inside the positioning groove 10, so as to further fix the first positioning plate 3 and the second positioning plate 4 and enhance the stability of the connection between the first positioning plate 3 and the second positioning plate 4.

[0026] Specifically, a connecting block 6 is fixedly installed on the end face of the first positioning plate 3, and a rubber mesh 7 is snapped into the connecting block 6. The surface of the rubber mesh 7 is provided with drainage holes, which prevents water and mud on the rubber mesh 7 from freezing in winter, thereby hindering drainage and ensuring the dryness of the bridge expansion joint structure.

[0027] Specifically, a waterstop 8 is fixedly installed below the connecting block 6, and the waterstop 8 is set in an arc shape so as to form a drainage function.

[0028] Working principle: First, the first positioning plate 3 is snapped into the inside of the L-shaped plate 5. Then, the L-shaped plate 5 is welded to the second positioning plate 4. Through the cooperation between the first positioning plate 3, the second positioning plate 4, and the L-shaped plate 5, and by using positioning bolts 11, they are fixedly installed in the slots 2 on the surface of the beam 1. This ensures good structural support stability and long service life. When damage occurs, it is easy to disassemble and replace them, which can effectively improve vehicle driving safety.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
