Description

Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to a bridge expansion joint with a buffer function. Background Art

[0002] A bridge is a building built for roads to cross natural or artificial obstacles. The expansion joint of a bridge is an important component of the bridge structure. It is mainly used to adjust the displacement and connection between the superstructures caused by vehicle loads and bridge construction materials. It is a device to adapt to the axial, bending and torsional capabilities of the bridge and to eliminate gaps between structures caused by factors such as temperature and settlement.

[0003] After searching, the authorization announcement number is CN219137391U, and the name is a utility model patent for a bridge expansion joint, which includes two bottom plates. Through research and analysis, it is found that although the other bottom plate can be moved by the movable hinge between the screw rod and the fixed plate, so that the two bottom plates can adjust the bridge joint, there are still the following disadvantages to a certain extent.

[0004] For example, because it does not have the function of buffering the expansion joint of the bridge during use, when passing vehicles pass through the expansion joint, it will cause pressure on the expansion joint, which will easily lead to damage of the expansion joint in the long run and reduce the service life of the bridge expansion joint. It also does not have an anti-slip function, so when a vehicle passes through the expansion joint of the bridge, the friction on the expansion joint of the bridge is small, which can easily cause the vehicle to slip and affect the passage of passing vehicles. In order to solve the above technical problems, we have designed a bridge expansion joint with a buffering function. Utility Model Content

[0005] The utility model aims to provide a bridge expansion joint with a buffering function, which has the advantages of buffering and anti-skid for the bridge expansion joint, and solves the problem of lack of buffering and anti-skid for the bridge expansion joint.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bridge expansion joint with a buffering function, comprising a bottom shell, a buffering assembly is installed in the inner cavity of the bottom shell, a connecting frame is installed on the top of the buffering assembly, a bridge expansion joint body is welded to the top of the connecting frame, an anti-skid assembly is installed on the top of the bridge expansion joint body, one side of the bottom shell is connected to a drainage shell by bolts, and the left and right sides of the drainage shell are fixedly connected with drainage pipes.

[0008] Preferably, the top end of the telescopic rod is fixedly connected to the bottom of the connecting frame by bolts, a connecting spring is provided on the movable sleeve on the surface of the telescopic rod, an elastic rubber pad is connected to the bottom of the inner cavity of the bottom shell by bolts, a through hole is provided on the surface of the elastic rubber pad, and the top and bottom ends of the connecting spring are respectively welded to the bottom of the connecting frame and the bottom of the inner cavity of the bottom shell.

[0009] Preferably, the anti-skid component includes a telescopic hose, the bottom end of which is fixedly connected to the top of the drainage shell, the top of the bridge expansion joint body is connected to an anti-skid plate by bolts, a long tube is penetrated through the surface of the anti-skid plate, and the left and right ends of the long tube are fixedly connected to one end of the telescopic hose.

[0010] Preferably, an anti-slip strip is welded to the top of the anti-slip plate, and water inlet holes are provided at the top of the long tube and the top of the anti-slip plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model has the function of buffering the expansion joint of the bridge by cooperating with an elastic rubber pad, a damper, a connecting spring, a telescopic rod, a supporting rod, a rotating rod, a short plate, a moving block and a moving rubber pad. When a vehicle passes through the expansion joint body of the bridge, the connecting frame presses down to squeeze and buffer the elastic rubber pad, and the rotating rod rotates to allow the moving block to squeeze and buffer the moving rubber pad. At the same time, the telescopic rod and the connecting spring contract. Under the action of the damper, the energy generated by the connecting spring can be consumed, thereby buffering the expansion joint body of the bridge again, protecting the expansion joint body of the bridge and increasing its service life.

[0014] 2. The utility model has the advantage of anti-skid by cooperating with a telescopic hose, an anti-skid plate, an anti-skid strip, a long tube, a drain pipe and a drain shell. Two anti-skid plates are fixed to the bridge expansion joint body by bolts, the long tube is passed between the two anti-skid plates, and then the long tube is connected with the telescopic hose. When a vehicle passes through the bridge expansion joint body, the anti-skid plate and the anti-skid strip can increase the friction force, thereby ensuring the stability of the vehicle passing. At the same time, on rainy days, rainwater can enter the long tube through the water inlet hole, be discharged into the drain shell through the telescopic hose, and be discharged through the drain pipe, so that the rainwater on the anti-skid plate can be better discharged, thereby preventing the phenomenon of slipping on rainy days and preventing the bridge expansion joint body from being affected by rainwater.
