Description

Technical Field

[0001] This utility model relates to the technical field of bridge expansion joint devices, specifically, to a water-stopping expansion joint device between beams of a high-speed railway. Background Technology

[0002] In recent years, my country's transportation construction has developed rapidly, with the number of bridges increasing by tens of thousands every year. To meet the requirements of bridge deck deformation, expansion joints are usually installed between the ends of two beams, between the beam end and the abutment, or at the hinged joints of the bridge. Due to the harsh operating environment of bridge expansion joints, which are exposed to the atmosphere for a long time, it is necessary to prevent rainwater or garbage and mud from clogging them. Existing bridge expansion joint water-stopping devices have a short service life and are troublesome to install and replace.

[0003] The applicant discovered through a search that Chinese patent document with publication number 203938964U, published on November 12, 2014, discloses a water-stopping structure for expansion joints of railway bridges, comprising: two F-shaped steels symmetrically arranged relative to the expansion joint and a waterproof sealing rubber strip. The grooved side of each F-shaped steel faces the expansion joint. The two ends of the waterproof sealing rubber strip are respectively set in the grooves of the two F-shaped steels, and the waterproof sealing rubber strip is in a "V"-shaped hanging state. The two ends of the waterproof sealing rubber strip are coated with a rubber-metal adhesive at the grooves of the F-shaped steels to bond the waterproof sealing rubber strip to the F-shaped steels to achieve a complete seal for waterproofing.

[0004] The device has low structural strength and short service life; moreover, its structure is complex and installation and replacement operations are difficult. Utility Model Content

[0005] The purpose of this utility model is to provide a high-speed railway beam-to-beam water-stopping expansion joint that is easy to install and replace, and has high structural strength.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a water-stopping expansion joint device between beams of a high-speed railway, comprising an elastic body disposed in the expansion joint, and a connecting rod provided on the elastic body.

[0007] The bottom of the elastic body is provided with a U-shaped groove; the connecting rod is disposed in the U-shaped groove, and its two ends are respectively connected to the inner wall of the U-shaped groove.

[0008] The connecting rod has an arc-shaped structure and its opening direction is opposite to that of the elastic body; the ends of the connecting rod are respectively connected to the inner walls of the U-shaped grooves facing each other.

[0009] The elastomer and the connecting rod are an integral structure.

[0010] The connecting rod is provided with a reinforcing hole; the reinforcing hole is located on the bottom surface of the connecting rod.

[0011] The connecting rods are evenly distributed in the U-shaped groove.

[0012] The elastic body is connected to the beam.

[0013] The end of the elastic body is provided with a connecting foot, which is connected to the beam.

[0014] The connecting feet are connected to the beam body by adhesive.

[0015] A sealing layer is provided between the top of the elastomer and the beam.

[0016] The beneficial effects of this application are as follows:

[0017] The elastic body has an arched structure and a U-shaped groove at the bottom; a connecting rod is provided in the U-shaped groove; the connecting rod and the elastic body are integral structures made of the same material and are evenly spaced along the longitudinal direction of the U-shaped groove;

[0018] This device uses the elastomer as a water-stopping device between beams in high-speed railways. The elastomer has excellent high tensile strength, high tensile strength, toughness and aging resistance. The elastomer can be used under various harsh climate and environmental conditions, and it will not age or deform after long-term use, which can effectively ensure the stable water-stopping function of the device for the expansion joint.

[0019] The U-shaped groove of the elastomer is provided with a connecting rod opposite to its opening direction; the connecting rod is also made of elastomer material, which has strong elasticity and toughness; when the elastomer is installed in the expansion joint, it is in a compressed state, and the connecting rod is also in a compressed state. At this time, the two ends of the connecting rod press the two sides of the elastomer tightly against the beams on both sides of the expansion joint, which enhances the stability of the connection of the device in the expansion joint; when it is necessary to remove the device, it is only necessary to pull down and fold the connecting rod to further compress the two ends of the elastomer inward, thereby detaching the elastomer from the expansion joint, which facilitates the disassembly of the device.

[0020] The connecting rod and the elastic body are an integral structure with high structural integrity. The connecting rod is not easy to detach from the elastic body and be damaged, which effectively enhances the structural stability of the device. The bottom surface of the connecting rod is provided with a reinforcing hole, which can not only enhance the structural strength of the connecting rod, but also effectively reduce the weight of the device.

[0021] The elastic body has connecting feet at its ends; when not installed, the width between the two connecting feet is greater than the width of the expansion joint; the elastic body is compressed from both sides towards the middle, thus entering the expansion joint; because the elastic body is in a compressed state and has high elasticity, the outer wall of the elastic body and the two connecting feet press firmly against the beams on both sides of the expansion joint, effectively preventing rainwater or garbage and mud from seeping into the expansion joint, effectively ensuring the water-stopping effect of the device; and the connecting feet are coated with adhesive between them and the beams, which ensures a stable connection between the device and the beams, and further enhances the device's water-blocking effect.

[0022] This device is easy to install and is not limited by climate or construction conditions. Furthermore, the elastomer can be prefabricated according to the width and expansion amount of the bridge expansion joint, and is not limited by the bridge expansion amount, thus having a wider range of applications.

[0033] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this utility model, and to facilitate its implementation.

[0034] Figure 1 The high-speed railway beam-to-beam water-stopping expansion joint shown includes an elastic body 1 installed in the expansion joint, and a connecting rod 2 is provided on the elastic body 1.

[0035] The elastomer 1 can be used in various harsh climates and environmental conditions, and it will not age or deform after long-term use, effectively ensuring the stable water-stopping function of the device for expansion joints; the connecting rod 2 can enhance the stability of the connection of the elastomer 1 in the expansion joint; when it is necessary to disassemble the device, simply pull down and fold the connecting rod 2 to further compress the two ends of the elastomer 1 inward, thereby detaching the elastomer 1 from the expansion joint, which facilitates the disassembly of the device; the connecting rod 2 can intercept rainwater, effectively extending the service life of the device and saving maintenance and replacement costs.

[0036] The bottom of the elastic body 1 is provided with a U-shaped groove 3; the connecting rod 2 is provided in the U-shaped groove 3, and its two ends are respectively connected to the inner wall of the U-shaped groove 3. The elastic body 1 has an arched structure, and the length of the elastic body 1 and the expansion joint are equal; the connecting rod 2 is provided at the bottom of the elastic body 1, and forms a cavity structure with the U-shaped groove 3.

[0037] The connecting rod 2 has an arc-shaped structure and its opening direction is opposite to that of the elastic body 1; the ends of the connecting rod 2 are respectively connected to the inner walls of the U-shaped groove 3 facing each other.

[0038] The connecting rod 2 is made of an elastomer material, which has strong elasticity and toughness. When the elastomer 1 is installed in the expansion joint, it is in a compressed state, and the connecting rod 2 is also in a compressed state. At this time, the two ends of the connecting rod 2 press the elastomer 1 tightly against the beams 4 on both sides of the expansion joint, which enhances the connection stability of this device in the expansion joint. When it is necessary to remove this device, simply pull down and fold the connecting rod 2 to further compress the two ends of the elastomer 1 inward, thereby detaching the elastomer 1 from the expansion joint and simplifying the disassembly of this device.

[0039] The connecting rod 2 and the elastic body 1 are integrated into one structure. The connection rod 2 and the elastic body 1 are integrated into one structure, which makes the structural integrity of the device high; the connecting rod 2 is not easy to detach from the elastic body 1 and be damaged, which effectively enhances the structural stability of the device and can increase the service life of the device.

[0040] The connecting rod 2 is provided with a reinforcing hole 21; the reinforcing hole 21 is located on the bottom surface of the connecting rod 2. The reinforcing hole 21 is a circular hole; the reinforcing hole 21 can effectively strengthen the structural strength of the connecting rod 2, and at the same time can significantly reduce the weight of the connecting rod 2, thereby achieving lightweighting of the device.

[0041] The connecting rods 2 are evenly distributed in the U-shaped groove 3. Along the longitudinal direction of the U-shaped groove 3, a connecting rod 2 is set at every predetermined interval; the elastic body 1 has an arched structure, and the connecting rods 2 are evenly arranged at the bottom of the elastic body 1 to provide stable support for the elastic body 1.

[0042] The elastic body 1 is connected to the beam 4. The connection between the elastic body 1 and the beam 4 allows the device to be stably fixed to the beam 4, thereby enabling it to perform normal water-stopping work for the expansion joint.

[0043] The end of the elastic body 1 is provided with a connecting foot 11, which is connected to the beam 4. When the elastic body 1 is not installed, the width between its two connecting feet 11 is greater than the width of the expansion joint. When the elastic body 1 is squeezed from both sides towards the middle, it is compressed and thus enters the interior of the expansion joint. Because the elastic body 1 is in a compressed state and has high elasticity, the outer wall of the elastic body 1 and the two connecting feet 11 are pressed tightly against the beam 4 on both sides of the expansion joint, which can effectively prevent rainwater or garbage and soil from seeping into the expansion joint and effectively ensure the water-stopping effect of this device.

[0044] Connecting foot 11 is connected to beam 4 by adhesive. Connecting foot 11 can increase the bonding area between elastomer 1 and beam 4, thereby strengthening the connection stability between the two.

[0045] A sealing layer 5 is provided between the top of the elastomer 1 and the beam 4. The sealing layer 5 is made of an elastomer material with good fluidity and can be cured at room temperature. The sealing layer 5 can prevent water or soil foreign objects from accumulating in the gap between the arc-shaped top of the elastomer 1 and the beam 4, thereby affecting the connection strength between the elastomer 1 and the beam 4.

[0046] The specific workflow of this utility model is as follows:

[0047] First, apply adhesive to the side wall of beam 4, then compress and install the elastomer 1 into the expansion joint, and finally pour the sealing layer 5 into the gap between beam 4 and elastomer 1.

[0048] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
