Product Description

Product Introduction
Description:
Our modular multi-group joints distinguish themselves with their remarkable structural design, unparalleled expansion and contraction capabilities, and superior waterproof properties. Boasting an elegant aesthetic, immense strength, long-lasting durability, and simplicity in installation and maintenance, these joints are engineered to perfection. Each unit accommodates a displacement range from 0-80mm, while the total number of units can be customized to meet the specific displacement demands of your bridge. Typically, these joints are capable of managing expansion and contraction ranges spanning from 160mm to an impressive 2000mm.
The Core Working Principle of Modular Multi-Group Joints
1. Support Transmission System
When high-speed vehicles pass over the expansion and contraction device, they generate both vertical and horizontal forces. The central beam is strategically mounted on a supportive crossbeam that spans the main spacing, forming an integrated force-bearing structure. This sophisticated system transmits the reaction forces generated by the expansion and contraction device to its edges while allowing it to move freely, accommodating the bridge deck's displacement seamlessly.
2. Elastic Control System
The interface between the supporting crossbeam and the pressure-bearing components functions as a sliding surface. By precisely managing the spring action, the device adapts to ongoing bridge deformations while maintaining consistent seam gaps. For seam widths greater than 35mm, the sealing tape can be conveniently replaced without any structural damage.
3. Waterproofing
The expertly crafted sealing rubber strip not only effectively seals the gaps between steel beams but also adapts effortlessly to structural changes due to expansion and contraction. The ends of the sealing rubber strip are meticulously integrated with the grooves of the steel profile, ensuring a secure, tight fit that resists detachment and maintains waterproof integrity.
