Excellent design, universal anti-seismic spherical bearings | Bearing prices
Hengshui Haotong Engineering Rubber Co., Ltd. specializes in the production of shock-absorbing spherical bearings,
for you Provide new
< shock-absorbing spherical bearings,
quotations,
< shock-absorbing spherical bearings,
construction plans, etc., directly supplied by manufacturers, with a wide range of products!
, Building design code: B "Steel Structure Design Code"
, National standard: B/- "Bridge Ball Bearing "Block"
Traffic standards: "Code for Design of Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts"
, Building design code: "Code for Seismic Design of Buildings."
The vertical pressure of the bearing is divided into,,,,,,,,,,,
The vertical pull-out force of the seat is determined within the vertical pressure
The horizontal shear resistance of the support is determined within the vertical pressure
The horizontal displacement stiffness of the support is between /~/
, The design angle is ., or the corresponding design can be made within the range of .~ according to the actual situation
, The horizontal displacement is: ~, the displacement designed due to fixed shock absorption is the displacement required for different projects The amount can be designed separately
When selecting the bearing, attention should be paid to the size of the bearing capacity, the size of the vertical tension, 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, you should pay attention to the type of support, namely two-way movable type, one-way movable type, and fixed type.
The constraint direction of the shock-absorbing support is given displacement and stiffness for the purpose of engineering shock absorption.

Installation
The installation plan and connection form of the bearing should be specifically agreed with the structural designer to ensure reliable connection between the upper and lower structures and the bearing. and function.
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 must be taken, or the method of intermittent welding on 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).
