Scope

Scope: This standard specifies the classification, structural forms, specifications and codes, technical requirements, test methods, inspection rules, marking, packaging, transportation, storage, and other precautions for prefabricated bridge expansion devices. This standard applies to comb-tooth plate bridge expansion devices (hereinafter referred to as expansion devices) with an expansion range of 80mm to 2400mm. Main technical content: The unit-assembled pre-stressed multi-directional displacement bridge expansion device effectively solves the technical challenges of bridge expansion devices in terms of assembly accuracy, mechanical performance, durability, environmental protection grade, and safety grade, and features standardized design, factory-processed fabrication, assembly-based installation, noise and vibration reduction, and maintenance-free operation. The assembly construction period is reduced by 85%, the amount of waste generated during the entire assembly process is reduced by 95%, and it can adapt to the displacement requirements in all directions of the bridge.
