Highway Bridge Expansion Device Testing Machine

【Highway Bridge Expansion Device Testing MachineScope of application:

This machine is a specialized testing device developed according to the testing requirements of relevant standards such as JT/T 327-2016 "General Technical Conditions for Highway Bridge Expansion Joint Devices". It is mainly used for assembly tolerance and waterproof performance testing in the field of bridge expansion devices, and has functions such as compression and tension of bridge expansion devices. It simulates the actual stress state of the expansion device in highway bridges and can be used for assembly tolerance and waterproof performance testing of modular single joint, double joint and other specimens.

【 Compliant with standards 】:

JT/T 327-2016 6.1.3.5.2 Assembly Tolerance Requirements - Compression Performance Testing

JT/T 327-2016 General Technical Conditions for Highway Bridge Expansion Devices Appendix C Waterproof Performance Test Method
