It can be designed as required if there are special needs
Price of shock-absorbing sliding bearing - grid sliding spherical joint bearing - Hebei shock-absorbing sliding bearing should bear tensile, compressive and shear (transverse) forces
Under the action of huge random seismic force, as long as the upper and lower structures themselves are not damaged, there will be no beam falling In general, the bearing is a weak link
Under the action of strong seismic force, it is very easy to drop beams and frames, and the strength and ductility of this bearing are higher than that of the structure itself
Therefore, it is especially suitable for the fortification of high-intensity seismic areas
The rotation angle is realized by the relative rotation between the ball core and the upper base plate, the base and the ball core; The displacement is realized by the sliding of the base in the box; The resistance to vertical tension is realized by sphere, base and box; The horizontal force is realized by the box, base and upper base plate; Spherical hinge bearings are divided into vibration damping spherical hinge steel bearings and seismic spherical hinge steel bearings

Steel corridor support
Since the bolt holes of the support and the bolt holes reserved on the construction site are made by the two units respectively, in the actual construction process, the bolt hole position is often not correctly made, and the steel corridor support can not be installed according to the requirements, so the bolt installation is not recommended

Corridor support steel rigid corridor sliding support, rigid corridor sliding support, seismic steel corridor support gcqz, easy to use, Taiheng Zhanjiang steel structure corridor spherical support technical index
Analysis of key design points of sliding support: the mechanical parameters of the support come from the stress of the node of reticulated shell structure
The rotation of the node and support shall be calculated respectively according to the center of the contact surface between the node and the support
The material selection of steel structure corridor spherical support
An important problem in the design of sliding bearing is to set a limit reset device and provide the expected sliding amount to prevent the structural damage caused by the sliding of corridor or collision with tower
Therefore, this connection method is generally used in the case of low corridor location and small span
