Things to note when selecting
When selecting a bearing, attention should be paid to the size of the bearing capacity, the size of the vertical pulling force, the size of the horizontal force and Pay attention to the displacement and rotation angle as well as the horizontal elastic stiffness.
When selecting a support, attention should be paid to the type of support, which is a two-way movable type, a one-way movable type, and a fixed type.
The constraint direction of the shock-absorbing bearing is given displacement and stiffness for the purpose of engineering shock absorption.

Installation of anti-seismic spherical bearing
The connection form of the installation plan of the bearing should be specifically agreed with the structural designer To ensure the reliable connection and function of the upper and lower structures and supports.
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 (as the width of the column section increases, the configuration of the horizontal stirrup section increases. The amount 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 design needs.
If welding is used to connect the bearing and the embedded steel plate, cooling must be taken Measures or the method of intermittent welding on opposite sides to prevent the steel parts of the support from overheating and damaging the PTFE plate rubber sealing ring and silicone grease.
Before installation, the elevation and levelness of the substructure should meet the design requirements. Bearing The height difference between the four corners should 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 is installed in place, the welding of the bottom plate and the embedded steel plate will meet the design requirements. Wait for After the construction of the beam body is completed, the temporary connectors should be removed immediately.
When installing the supports, the connectors between the upper support plate and the lower support plate must be installed. After the support installation is completed, remove them and install the upper support immediately. Dust cover (the dust cover is a rubber plate and is installed by the on-site construction unit).

Maintenance
Bearing During use, perform regular inspections and maintenance every time.
Check whether the supports and upper and lower connections are damaged, check whether the bolts are sheared or loose, whether the welds are cracked, etc.
Check the dust accumulation in the dust cover and remove it Dust.
Check the rubber sealing ring for cracks and aging.
Rotate the fixing nut, clean it and re-oil it to avoid rust.
Check the height change of the support itself. This change reflects the polymerization reaction. The wear condition of the PTFE plate should be overhauled when the height change exceeds mm.
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 and then repaint.
Special After the occurrence of situations (such as earthquakes, destructive winds, etc.), the above contents should be checked promptly.
