Product Description

Enchanting Product Introduction
Captivating Description:
Our Modular Multi-Group Expansion Joints are marvels of engineering, crafted with exquisite precision and state-of-the-art technology. They distinguish themselves through an exceptional structural design, a remarkable range of expansion and contraction, superior waterproofing capabilities, a visually appealing aesthetic, robust strength, extended service life, and hassle-free installation and maintenance. Each modular group effortlessly accommodates a displacement range of 0-80mm, with the total number of groups meticulously customized to address the specific displacement requirements of the bridge. The overall span of expansion and contraction ranges from an impressive 160mm to a staggering 2000mm.
The Ingenious Working Principle of Modular Multi-Group Joints
1. Support Transmission System
As vehicles speed over the expansion joints, a combination of vertical and horizontal forces is generated. The central beam of the joint is firmly anchored to a supporting crossbeam that spans the primary spacing. This configuration forms a cohesive, force-bearing structure that efficiently transmits reaction forces from the expansion joint to its edges. Concurrently, the joint dynamically adjusts to accommodate the expansion and contraction of the bridge deck.
2. Elastic Control System
The interface between the supporting crossbeam and the pressure bearings is ingeniously designed as a sliding surface. Utilizing the resilient power of springs, the expansion device seamlessly adapts to continuous bridge deformation, ensuring consistently maintained gaps. For seam widths surpassing 35mm, the sealing tape can be easily replaced without any structural disruption.
3. Impeccable Waterproofness
Our masterfully engineered sealing rubber strip not only effectively seals the gaps between steel beams but also skillfully adjusts to structural expansion and contraction. The ends of the sealing rubber strip are precisely aligned with the grooves of the steel profile, ensuring a secure, detachment-resistant fit.
