Introduction
It has the characteristics of large horizontal displacement and flexible rolling, and has the advantages of light weight, compact structure, simple structure, low building height, convenient processing and manufacturing, saving steel and reducing cost. , is an ideal bearing suitable for large collapsed bridges. This series of pot-type rubber bearings has a bearing capacity of 100%, and the bearing capacity can meet the needs of large-scale bridge construction.
In this specification series, the horizontal bearing capacity of the fixed bearing in all directions and the non-slip direction of the one-way movable bearing is not less than the vertical bearing capacity of the bearing. The horizontal bearing capacity of the anti-seismic pot-type rubber bearing is not less than the vertical bearing capacity of the bearing. The rolling angle of the bearing is not greater than that after adding silicone grease lubrication, and the friction coefficient of the normal temperature movable bearing is designed to be the smallest
Characteristics of basin-type bearings

Based on rubber bearings Above, further improved and more complete rubber bearings. _ Basin-type rubber bearing
Deformation mechanism
Use the restraints of the rubber blocks on the bottom basin to obtain a larger capacity. Use the center lining PTFE plate and the top plate stainless steel plate to achieve a low friction coefficient and a large level. The displacement uses the pot's three-force elastic rubber block to evenly compress the large angle.

Precautions
It is recommended to set supporting padding stones on the top surfaces of piers and platforms.
, basin-type rubber bearing
should be unpacked for comprehensive inspection and cleaning before installation. Remove oil stains, especially the relative sliding surfaces of stainless steel and filled PTFE plates. Carefully wipe them clean with alcohol. Other parts of the bearing should also be wiped clean. Do not apply anti-rust oil inside the bearing.
In addition to the fact that the elevation of the bearing must meet the planning requirements, in order to ensure the performance of the pot-type rubber bearing
, the plane level in three directions must be ensured.
The upper and lower parts of the support must be aligned vertically and horizontally, or because the temperature during installation is different from the planned temperature, the pot-type rubber bearing
The vertically staggered distance between the upper and lower parts must be in accordance with the calculation. The value remains unchanged.
The center line of the support and the center line of the main beam should coincide or be kept parallel.
When carrying out system transformation on continuous bridges, it is necessary to adopt thermal insulation measures between the pot-type rubber bearings
and the sulfur cement slurry blocks to avoid damage to the filled PTFE plates and rubber blocks.

The production of seismic isolation bearings includes two large Partial rubber and steel plate production. After these two parts are prepared, stack a layer of steel plate and a layer of rubber, seal the upper and lower ends with thicker steel plates, and wrap a thick layer of rubber around them. Then, put them into the mold and keep them under high temperature and high pressure conditions. In a few hours, the isolation bearing will be ready.
