Solution! First-class price for anti-seismic spherical bearings!
Hengshui Haotong Engineering Rubber Co., Ltd. specializes in the production of steel structure shock-absorbing spherical steel bearings
. The products are sold at home and abroad. The production of
< steel structure shock-absorbing spherical steel bearings
/>Passed national certification standards!
, can carry vertical load
, has the performance of resisting vertical tensile force, ensuring that it can move up and down during vertical earthquakes The structure is not out of joint
It has the performance of resisting horizontal force to ensure that the structure is not out of joint during horizontal earthquakes
It can adapt to the radial and circumferential displacement requirements
It can adapt to the angle requirements in any direction
/> , The shock-absorbing bearing has good shock-absorbing performance
The bearing transmits force through the spherical surface, and there is no force necking phenomenon. The reaction force acting on the upper and lower structures is relatively uniform
. The seat does not use rubber to bear pressure, and there is no impact of rubber aging on the support, and the service life is long.
The installation plan and connection form of the bearings should be specifically agreed with the structural designer to ensure the stability of the upper and lower structures and the bearings. Reliable connection and functionality.
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 .b to .b from the top of the column along the column axis to the column foot (b is the column cross-section width), To increase the configuration of the horizontal stirrup section, the amount of increase is determined based on the bearing capacity analysis results.
The movable support sets an offset value between the upper support plate and the sliding plate according to design needs.
If the connection between the support and the embedded steel plate is welded, cooling measures should be taken, or the method of intermittent welding on the opposite sides can be used to prevent the support steel parts from overheating and damaging the polytetrafluoroethylene plate, rubber sealing ring and Silicone grease.
Before installation, the elevation and levelness of the substructure should meet the design 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 supports are installed 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 connections should be removed immediately.
When installing the support, the connection between the upper support plate and the lower support plate must be installed. After the support is installed, remove it and install the dust cover immediately (the dust cover is a rubber plate , the same on-site construction unit is responsible for installation).
During the use of the bearings, check and maintain them regularly.
. Check whether the support and the upper and lower connecting parts are damaged, check whether the bolts are sheared or loose, and whether the welds are cracked, etc.
Check the dust accumulation in the dust cover and remove the dust.
. Check the rubber sealing ring for cracks and aging.
, Turn the fixing nut, clean it and re-oil it to avoid rust.
. Check the height change of the support itself. This change reflects the wear of the PTFE plate. When the height change exceeds mm, it should be overhauled.
. Check the integrity of the anti-rust paint. If there is any peeling off, use emery cloth to grind out the steel body and give it a metallic luster before repainting.
After special circumstances occur (such as earthquakes, destructive winds, etc.), the above contents should be checked in time.
