Is the price of Expansion joint in Hebei high? What is the main function of Expansion joint
Is the price of Expansion joint in Hebei high? What is the difference between Expansion joint and settlement joint: Expansion joint, also called temperature joint, is a joint set to prevent deformation caused by temperature. The Expansion joint shall start from the top of the foundation and be disconnected from the wall, floor and roof. The foundation is buried underground and is less affected by temperature, so it does not need to be disconnected. If the roof of the building adopts tile roof, Expansion joint is not required for the roof. The spacing of Expansion joint is closely related to the material, structure type, construction method, location and environment of the component.

How long does the rubber bearing need to be replaced
In fact, when we discover abnormal deformation of the rubber bearing, we need to quickly stop replacing it. This situation is mainly due to the lack of leveling during the construction process, which leads to significant initial shear deformation of the bearing and the inability to guarantee its function. So at this point, we need to quickly stop and replace it to ensure that the rubber bearings play their due role and prevent hidden dangers.

What should be paid attention to during the construction of rubber bearings
When checking the rotation angle of rubber bearings, it is necessary to consider the impact of uncertainty in the compressive elastic modulus and take the upper limit of the compressive elastic modulus for calculation. We also need to consider temperature factors together to advance the rolling function of the rubber bearing itself. In terms of construction, strictly follow the specifications and level the upper and lower load-bearing steel plates. If there are no upper and lower load-bearing steel plates, the top surface of the pad stones supported by the pier and abutment should be leveled, and the relative level difference of each pad stone should be controlled within 1mm.
