The production and installation of the bridge bearing manufacturer tells you the characteristics of the bridge expansion joint: the bridge expansion joint has the characteristics of reliable connection, stable connection with the pavement, sealing and waterproof, flexible expansion, stable driving, and durability. This product is parallel to and perpendicular to the axle shaft. It can expand at will. It is firm and reliable. The car runs smoothly without sudden jumping and noise; It can prevent precipitation and garbage from infiltrating and blocking; Installation, inspection, maintenance and dirt removal shall be simple and convenient. This product is applicable to the design load of grade 120 straight bridges, curved bridges, skew bridges, skew bridges and other urban bridges.

Bridge expansion joint steel side beam 16Mn finish rolling, anchor plate and Φ 16 The bolt has good mechanical properties. The vehicle impact force applied to the side beam shall be transferred to the beam body according to the balance of the anchoring member. After the expansion device is put into the groove, it should be basically calibrated. Use a 3 meter ruler and feeler gauge to detect a point every 1 meter. The flatness should be kept at 0~1mm. At the detection point, weld the embedded reinforcement and anchor ring reinforcement, and temporarily fix its position. And gradually retreat until it is adjusted and welded to the whole joint to meet the requirements. The whole rubber strip of the bridge expansion joint is made of rubber, neoprene or EPDM, with good aging resistance and bending resistance characteristics.

Because the bridge expansion joint is composed of steel edge beam, bird-shaped rubber sealing strip and anchor components. When the bridge is offset due to temperature difference and other factors, the rubber sealing strip mechanically fixed in the side beam pipe trench can be folded and expanded at will to play the role of waterproof and dustproof. The impact force of the vehicle is transferred to the bridge structure according to the side beam and the welded anchor components.

The above is about the characteristics of bridge expansion joints introduced by the manufacturer of bridge bearings. If you still don't understand anything, you can leave a message or contact us.
