Description

Technical Field

[0001] This utility model relates to the technical field of bridge expansion joints, and specifically to a bridge expansion joint. Background Technology

[0002] Bridge expansion joints are retractable structures installed at the expansion joints of bridges. They are an important part of the bridge structure and can adjust the length, height, or position of the bridge according to the influence of stress and environmental changes to adapt to the deformation of the bridge structure.

[0003] Existing bridge expansion joints have poor drainage performance, and rainwater tends to accumulate at the expansion joints on the bridge deck. This water can easily seep into the bridge structure, causing erosion of critical components such as beams and supports, and affecting the bridge's durability and safety.

[0004] For example, the bridge expansion joint disclosed in patent CN204023398U does not have a drainage structure. This may cause water to easily accumulate between the vertical steel plate and the water-stop tape when it rains or when there is water on the bridge surface, forming puddles. Long-term water accumulation will not only affect the normal use of the bridge expansion joint and accelerate the aging and corrosion of the materials, but also reduce the adhesion between the road surface and the vehicle tires, increasing the risk of vehicle skidding.

[0005] Therefore, it is necessary to invent a bridge expansion joint to solve the above problems. Utility Model Content

A second sliding groove is formed at the contact position between the side wall of the F-shaped side beam and the slider. Locking mechanisms are provided on the side walls at both ends of the drainage channel.

[0008] Preferably, two F-shaped side beams are provided, and a rubber sealing strip is provided between the two F-shaped side beams. The rubber sealing strip has a "V" shaped structure design. The rubber sealing strip enhances the sealing performance of the expansion joint and prevents moisture, dust and other debris from entering the expansion device.

[0009] Preferably, the upper part of the rubber sealing strip is provided with a waterproof rubber strip made of rubber material, which further enhances the waterproof performance of the telescopic device.

[0010] Preferably, the water guide groove is provided with multiple water guide grooves arranged in an inclined slope and evenly distributed at equal intervals, and the low part of the water guide groove is located at the water inlet end of the drainage groove.

[0011] Preferably, the bottom of the drainage groove is provided with a drainage hole, and the drainage groove is designed in a right triangle, which is beneficial to rapid drainage and reduces the potential damage of accumulated water to the bridge structure.

[0012] Preferably, the sliding block is connected with the first and second sliding grooves, and the sliding block and the first and second sliding grooves are provided with multiple sliding grooves, which facilitates the installation, disassembly and cleaning of the filter screen.

[0013] Preferably, the locking mechanism comprises a triangular connecting piece, a connecting plate, a fixing bolt and a screw hole, the triangular connecting piece is located on the side wall of the drainage groove, and the connecting plate is hinged on the triangular connecting piece.
