【Scope of application】
This machine is a special test device developed according to the test requirements of JT/T 327-2016 "General Technical Conditions for Expansion Joints of Highway Bridges" and other relevant standards. It can simulate the actual stress state of expansion devices on highway bridges and is mainly used for bridge expansion and contraction. Deformation performance, assembly tolerance, waterproof performance, horizontal friction resistance test in the field of equipment, suitable for single-slit, double-slit and multi-slit modular expansion devices, comb plate expansion devices and other test samples.
