What are the applications of comb plate expansion device in road engineering
2026-07-13The comb plate relies on the sliding of meshing steel plates to adapt to the expansion and contraction of the beam body, with an expansion range of 40-1000mm. It has smooth driving, good noise reduction effect, strong bearing capacity, and can adapt to multi-directional displacement. It is divided into two major sections: new construction and old bridge renovation.

What are the material characteristics of the JQZ series ball bearings
2026-07-06JQZ multi-level horizontal force ball shaped steel bearings are divided into four categories of materials: steel structure main body, sliding wear-resistant pair, sealing element, and anchoring accessories. The materials, mechanics, weather resistance, and friction characteristics of each component are explained separately:

Where are pot type rubber bearings suitable for railway rail transit bridges
2026-06-29Core advantages of pot type rubber bearings: large load-bearing capacity, large horizontal expansion displacement, flexible rotation, weather resistant sealing, and ability to withstand repeated train impact braking force. They are specifically designed for heavy-duty, large-span, and complex deformation railway bridges that plate bearings cannot meet. They are suitable for four major scenarios: c

What is the function of cable supports for highway bridges
2026-06-221、 Transmitting the enormous pulling force of the cable and dispersing the load The tension force, vehicle live load, and self weight of the inclined cable are all transmitted to the main beam or bridge tower through the support, avoiding direct compression of the concrete beam/tower body by the cable.

What is the function of pot type rubber bearings for highway bridges
2026-06-15Basin type bearings are the main load-bearing bearings for large-span bridges, relying on steel basins, rubber compression, sliding/rotating structures to bear all the stress and deformation coordination between the upper part of the bridge and the piers and abutments. The five core functions are:

Where are plate rubber bearings used on highway bridges
2026-06-08Plate type rubber bearings rely on rubber elastic deformation to achieve vertical load-bearing, horizontal displacement, angular deformation, and shock absorption and buffering. They are the most commonly used type of bearings for highway bridges, divided into two categories: ordinary plate type and PTFE skateboard type. The scenarios are as follows:

What is the purpose of lead core seismic isolation rubber bearings
2026-05-25Lead core isolation rubber bearings (LRBs) are key seismic components installed between the foundation and upper part of a structure. Their core functions include vertical load-bearing, horizontal isolation, energy dissipation and seismic reduction, post earthquake reset, and protection of buildings and bridges during earthquakes.
