Compression performance tests for determining the assembly tolerance size of expansion joint devices in the field of bridge expansion are used to simulate the actual stress state of expansion devices in highway bridges. They can be used for testing samples such as single-seam modulus test devices and multi-seam modulus test devices, as well as waterproof performance testing methods.
The Microcomputer Controlled Electronic Tensile Testing Machine, specifically designed by Beijing Lanhang Zhongke Measurement and Control Technology Research Institute for rubber sealing strips in highway bridge expansion joints. The computer system, through a fully digital controller, controls the rotation of a high-precision stepping motor via a speed control system. After deceleration by the deceleration system, it drives the movement of the moving crossbeam via a precision ball screw pair, completing the repeated tensile mechanical performance test of the sample. It is suitable for rubber sealing strip performance testing in highway bridges and other applications. The equipment meets the requirements of JT/T326-2016 "General Technical Conditions for Highway Bridge Expansion Joints".
