Structure & Design Principle
The performance of this product stems from the synergistic working mechanism of its laminated composite structure. The embedded high-strength steel plates effectively constrain the Poisson's expansion of the rubber, thereby significantly enhancing the vertical stiffness and compressive stability of the bearing. Concurrently, the intermediate rubber layers can deform freely under shear forces, providing the necessary horizontal flexibility for the superstructure. This “rigidity-flexibility combination” design enables it to simultaneously meet the comprehensive mechanical requirements of vertical load bearing, horizontal movement accommodation, and slight rotation.
Material & Durability
The rubber layers are typically made from materials such as Natural Rubber (NR) and Neoprene (CR), which offer good elasticity and aging resistance. Natural rubber provides excellent elastic recovery, while neoprene performs well in resistance to oils, ozone, and atmospheric aging, making it adaptable to various environmental conditions. The steel plates are made of high-strength steel, providing stable support and necessary rigidity for the core structure. The rubber and steel are securely bonded through vulcanization. This composite structure helps the bearing maintain its shape stability under long-term loading and preserve its designed performance under common temperature variations and exposure conditions.
Technical Parameters & Customization
The key parameters of the product, including plan dimensions (typically rectangular or circular), total height, individual rubber layer thickness, number and thickness of internal steel plates, can all be customized according to the specific requirements of the bridge project. The customization process is typically based on technical documentation or specific performance requirements provided by the project party. By adjusting these parameters accordingly, the bearing's performance can be precisely matched to the project's demands, aiding in achieving the intended support and movement accommodation functions under specific engineering conditions.
Primary Application Scenarios
This product is primarily suitable for bridge engineering projects such as highway bridges, railway bridges, viaducts, and overpasses, serving as a key support component connecting the superstructure beams to the substructure piers and abutments. It is also commonly used in joints of large building structures and equipment foundations that require release of thermal stress and provision of elastic support.
FAQ
Q：How do I select the appropriate bearing type and parameters for my bridge project?
A：Bearing selection must be based on specific design conditions, including vertical reaction force, horizontal displacement magnitude, rotation requirements, beam bottom dimensions, and applicable standards. It is recommended to provide your design drawings or parameters, and we will provide a customized solution.
Q：What should be noted during installation?
A: Installation requires ensuring the bearing seat surface is level, clean, and at the correct elevation. The bearing should be placed centrally, making full contact with the beam bottom and the bearing seat. Impacts or improper twisting of the bearing during construction should be avoided.
