Fixed anti-seismic spherical hinge bearing
Planning parameters< br/> The vertical pressure of the support is divided into
The vertical pull-out resistance of the support is taken as the internal load of the vertical load
The horizontal shear resistance of the support is taken as the internal load of the vertical load
The planning angle is It can also be planned accordingly in the enclosure according to the actual situation
The displacement-type bearing can be set to the corresponding displacement amount according to its displacement mode. It can also be planned according to the actual needs
Sliding friction coefficient of the bearing ()< br/> Two fixed anti-seismic spherical hinge bearings
Things that should be paid attention to when selecting
When selecting a bearing, you should pay attention 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. The horizontal elastic stiffness of the shock-absorbing bearing should also be paid attention to.
When selecting a support, you should pay attention to the type of the support, which is a two-way movable type, a one-way movable type, and a fixed type.
The displacement and stiffness are determined in the binding direction of the shock-absorbing bearing for the purpose of engineering shock-absorbing.
Installation of three-fixed anti-seismic spherical hinge bearings
The installation plan and connection method of the bearings should be agreed upon in detail with the structural planner to ensure the reliable connection and function of the upper and lower structures and the bearings.
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 increase in the horizontal stirrup section for the increase in the width of the column section) The quantity is determined based on the bearing capacity analysis results.
The movable bearing sets an offset between the upper bearing plate and the sliding plate according to the design requirements.
If welding is used to connect the bearing and the embedded steel plate, cooling must be adopted Measures or intermittent welding of 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 level of the substructure should meet the planning 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 planning requirements. Wait for The temporary connecting parts should be removed immediately after the construction of the beam body.
When installing the supports, it is necessary to install the connecting parts between the upper support plate and the lower support plate. After the installation of the supports is completed, they should be removed and installed immediately. Dust cover (the dust cover is installed by the rubber plate and on-site construction unit).
Maintenance of the four-fixed anti-seismic spherical hinge bearing
Regular inspection and maintenance should be performed every time the bearing is in use. .
Check whether the support and the upper and lower connecting parts 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 the dust.
Check the rubber sealing ring for cracks and aging.
Rotate the fixing nut and clean it, then apply oil from the head to avoid rust.
Check the height change of the support itself. This change will reflect the wear of the polymer when the height changes. If it exceeds ㎜, it should be overhauled.
Check the integrity of the anti-rust paint. If it has fallen off, use emery cloth to grind out the steel body and show the metallic luster, then paint it again.
After special circumstances (such as earthquake destructive force) Feng et al. should check the above content in time.
