Main technical features of the finished hinged sliding bearing
Can withstand vertical load
Have considerable resistance to vertical pull-out force, ensuring that the upper and lower structures are not disconnected when vertically pulled out, and can function normally Corner
It has the performance of resisting horizontal shear force to ensure that it does not fall off when horizontal force is applied
It can meet the horizontal displacement requirements
It can meet the universal rotation and universal load bearing
The material is alloy casting Steel, fully meeting the project life span.
Design of finished hinged sliding bearings
Architectural design specifications Steel structure design specifications
National standards/bridge spherical bearings
Traffic standards highway reinforced concrete and prestressed concrete bridge and culvert design Code
Building Design Code Code for seismic design of buildings.
Design parameters of the finished hinged sliding bearing
The vertical pressure is divided into
The vertical pull-out resistance is taken as the internal load of the vertical load
The horizontal shear resistance is taken as the internal load of the vertical load ~
The design angle is also can be designed accordingly according to the actual situation
Sliding friction coefficient (~)
Matters that should be paid attention to when selecting the finished hinged sliding bearing
Selection When hinged supports, 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 the displacement and angle. For shock-absorbing supports, the horizontal elastic stiffness should also be paid attention to.
When selecting a hinge support, attention should be paid to the type of support, that is, two-way movable type, one-way movable type, and fixed type.
The constraint direction of the damping hinge support is given displacement and stiffness for the purpose of engineering shock absorption.
Installation of finished hinged sliding bearing
The connection form of the hinged bearing installation plan should be specifically agreed with the structural designer to ensure reliable connection and functional performance of the upper and lower structures and the bearing.
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 (for the configuration of the horizontal stirrup section as the width of the column section increases, The increase is determined based on the bearing capacity analysis results.
The movable hinge support sets an offset value between the upper support plate and the sliding plate according to design requirements.
If the connection between the hinge support and the embedded steel plate is welded When installing, cooling measures or intermittent welding of opposite sides should be taken to prevent the steel parts of the hinge support from overheating and damaging the polytetrafluoroethylene plate, rubber sealing ring and silicone grease.
Before installation, the elevation of the substructure should be adjusted and levelness meet the design requirements. The height difference between the four corners of the hinge support should not be greater than mm.
The center line of the hinge support should coincide with the center line of the main beam and the installation line of the lower structure.
After the hinge support is installed in place , the welding of the bottom plate and the embedded steel plate meets the design requirements. After the construction of the beam body is completed, the temporary connectors should be removed immediately.
When installing the hinge support, the connector between the upper support plate and the lower support plate must be installed OK, 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 installing it).
Maintenance of the finished hinged sliding bearing
During the period of use of the hinge support, check and maintain it regularly.
Check whether the hinge 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 dustproof Check the dust accumulation in the 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 hinge 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 remove it. Repaint after showing metallic luster.
After special circumstances occur (such as earthquakes, destructive winds, etc.), the above content should be checked in time.
