One-way anti-seismic spherical hinge bearing
Primary technical performance
, friction coefficient of the bearing is
, horizontal shear force of the bearing is greater than the vertical bearing capacity< br/> , The pull-out force and tensile strength of the bearing are the vertical bearing capacity
, The vertical bearing capacity of the bearing is divided into grades
, The bearing rotation angle is
, The bearing is suitable Temperature range ℃~+℃
One-way anti-seismic spherical hinge bearing
Installation
The installation plan and connection method of the spherical bearing should be discussed in detail with the structural planner to ensure that the upper and lower parts Reliable connection and functional performance of structure and support.
The number of the lower reinforced concrete column shall not be lower than grade 1.
The internal reinforcement of the column should refer to the research and analysis results during the design of this support, that is, within the height range from the top of the column along the column axis to the column foot (the configuration of the horizontal stirrup section to increase the width of the column section , the increase is determined based on the bearing capacity analysis results.
, The movable bearing sets an offset value between the upper bearing plate and the sliding plate according to planning needs.
, If the connection between the bearing and the embedded steel plate is selected When welding, cooling measures should be taken, or intermittent welding of opposite sides should be adopted to prevent the steel parts of the support from overheating and damaging the polytetrafluoroethylene plate, rubber sealing ring and silicone grease.
Before installation, the lower structure should be The elevation and levelness meet the planning requirements. The height difference between the four corners of the support shall not be greater than mm.
, The center line of the support should coincide with the center line of the main beam and the installation line of the lower structure.
, After the support device is in place , the welding of the base plate and the embedded steel plate meets the design requirements. After the construction of the beam body is completed, the temporary connecting parts should be removed immediately.
, When installing the supports, it is necessary to connect the connecting parts between the upper support plate and the lower support plate. After the installation is complete, remove it after the bearing is installed in place, and install the dust cover immediately (the dust cover is a rubber plate, and the on-site construction unit is responsible for installation).

One-way anti-seismic ball joint Maintenance of the bearing
. Check and maintain the bearing regularly every time during use.
Check whether the bearing and the upper and lower connecting parts are damaged, and check whether the bolts are sheared. Or loose, whether the weld is cracked, etc.
, Check the dust accumulation in the dust cover, and remove the dust.
, Check the rubber sealing ring for cracks and aging.
, Rotate the fixing nut, clean it and then oil it from the head to prevent rust.
, Check the height change of the support itself. This change reflects the wear and tear of the aggregate. When the height change exceeds mm, it should be overhauled.
, Check the integrity of the anti-rust paint. If it falls off, use emery cloth to grind out the steel body and show the metallic luster before repainting.
