Why use plate type rubber bearings for highway bridges
2025-10-10Plate type rubber bearings for highway bridges are the core load-bearing components that connect the upper structure (such as beams) and lower structure (such as piers and abutments) of the bridge. Their core value lies in the elastic properties of rubber, which simultaneously achieve the three functions of "load-bearing, displacement adjustment, and shock absorption and buffering", solving the st

What is the main purpose of special bearings for highway bridges to solve
2025-09-08Special bearings for highway bridges are specialized bearings designed for complex working conditions or special functional requirements that conventional bearings cannot meet. Their core function is to solve the problems of bridge structural deformation, force transmission, environmental adaptation, and functional expansion that conventional bearings cannot cope with, ensuring the safety, stabili
-
How does the comb plate expansion device perform in low-temperature environments
2025-09-03The performance of the comb plate expansion device in low temperature environments (usually referring to temperatures ≤ -10 ℃, and can be as low as -30 ℃ in severe cold areas) is influenced by three core factors: material characteristics, structural design, and installation processes. The overall performance shows the characteristic of "retaining rigid advantages but highlighting flexible shortcom
