Engineering safety upgrade from earthquake resistance to full-scenario adaptation

In the field of infrastructure engineering, bearings are key components connecting structures and foundations, and their technological breakthroughs directly affect the life and safety of the project. Hengshui Guoheng Rubber and Plastic Products Co., Ltd. recently launched a number of innovative bearing products, which meet the needs of complex working conditions with differentiated designs and provide full-scenario solutions for buildings, bridges, railways and other fields.

Seismic isolation bearings: "safety cushions" in earthquakes

Adopting a multi-layer rubber and steel plate alternating stacking structure, the vertical bearing capacity is more than 5000kN, and the horizontal stiffness is 40% lower than that of traditional bearings, which can effectively resolve earthquake energy above 8 degrees. Its unique three-way constraint design increases the horizontal displacement allowable value to ±300mm, and has been applied to the Sichuan-Tibet Railway Tunnel Project, significantly improving the seismic performance.

Basin bearing: "intelligent regulator" with large bearing capacity

Through the fluid characteristics of the elastic rubber block in the steel basin, efficient rotation under three-way force state is achieved. With the low friction design of polytetrafluoroethylene plate and stainless steel plate, the horizontal displacement capacity reaches 1000mm and the bearing capacity exceeds 100,000 kN. This product successfully solves the problem of easy detachment of large-span bridge bearings and achieves zero-fault operation in the Xiong'an New Area Cross-River Bridge Project.

Spherical bearing: "free deformation node" of large-span space

The tensile spherical steel bearing can withstand pressure and tension at the same time through spherical contact design, and the ability to release temperature stress is increased by 3 times. It is suitable for space structures such as grids and domes. Its modular installation method shortens the construction period by 50% and has been applied to a stadium project in Southeast Asia to achieve precise control of millimeter-level displacement.

Plate rubber bearing: economical and efficient "basic guardian"

There are two series: ordinary type and polytetrafluoroethylene skateboard type, covering the needs of bridges below 5000kN. The former provides reliable force transmission with a multi-layer rubber-steel plate vulcanized structure, and the latter achieves resistance-free sliding through a 2mm polytetrafluoroethylene plate, reducing maintenance costs by 60%, becoming the preferred solution for small and medium-span bridges.

From earthquake-zone railways to cross-sea bridges, from urban elevated roads to industrial plants, Guoheng Rubber and Plastics has redefined the performance boundaries of bearings through material innovation and structural optimization. In the future, with the deep integration of intelligent monitoring technology and bearing products, engineering safety will enter a new era of "active defense".
