A multi-directional movable spherical steel bearing
The reaction force of the upper structure of the bridge can be reliably transmitted and at the same time it can realize the deformation (horizontal displacement and rotation angle) required by the beam structure. According to these requirements, the bridge support should be designed to have sufficient stiffness in the vertical direction to ensure that the support is less flexible under the maximum vertical load. The bridge support should have a certain degree of flexibility in the horizontal direction to adapt to the braking force of the beam. The horizontal displacement caused by the shortening, creep, and load effects of concrete at high temperature. At the same time, the bridge bearings should also adapt to the rolling specifications and models of the beam ends. Multi-directional movable longitudinal movable fixed bearings

Features
① The anti-seismic spherical steel bearing can roll in all directions and carry load in all directions, which can well meet the requirements of various loads on the superstructure. The transmission of reaction force requires rolling movement to ensure that the resultant force of the reaction force is concentrated clearly, safely and reliably.
② The anti-seismic spherical steel bearing can withstand tension, compression and shear (lateral) forces. Under the effect of infinite random earthquake forces, it only needs to be constructed independently up and down. If damaged, catastrophic consequences such as falling beams and falling frames will not occur, so it is particularly suitable for fortification in high-intensity seismic areas and has the ability to withstand seismic intensity.
③ The static stiffness of the anti-seismic spherical steel bearing is large in trains and large cars Under the influence of infinite self-weight and inertial force, the bearing only undergoes minimal deformation, which can reliably ensure the smoothness of cars and trains when running at high speed.
④ The anti-seismic spherical steel bearing has a large force-bearing area through the spherical surface and is made of a variety of materials The optimized combination of materials greatly reduces the volume and height. It is lightweight, easy to install, and has a lower cost than steel bearings with the same bearing capacity.
⑤ The anti-seismic spherical steel bearing has a wide applicable temperature range (℃℃, good durability and performance). There is no impact of rubber aging on the rolling function of the bearing when bearing pressure
