Modular Expansion Joint Product Brief
It consists of side beam, middle beam, supporting beam, rubber sealing strip, sliding spring, sliding support and control spring. It is a traditional structure expansion device.
With a certain amount of lateral displacement and vertical displacement.
Control system: polyurethane control spring to achieve, to adapt to structural deformation, balance the force between beams, ensure that the middle beam spacing is equal, effective absorption of vehicle impact load.
Supporting system: The flexible and sliding support is provided in the movement direction of the expansion device. The pre-compression of the sliding spring prevents the offset of the supporting elements and compensates the manufacturing tolerance. The design of the sliding support can absorb the composite inclination of the supporting beam and reduce the torsional stiffness to compensate the height difference of the side beams at both ends.
Main specifications: D160, D240, D320, D400D480, D560, D640 and other seven levels.
Suitable for bridge engineering whose expansion is not greater than 640 mm (special design for more than 640 mm)
