Product Description

Product Introduction
Description:
Our Modular Multi-Group Joints are a marvel of meticulous engineering, designed to deliver unparalleled benefits such as robust structural integrity, a vast range of movement, superior waterproofing, and a refined aesthetic appeal. These joints are built to last and are remarkably easy to install, accommodating a displacement range of 0-80mm to meet the specific needs of any bridge. The extension and contraction span from a general 160mm to an impressive 2000mm.
The Main Working Principle of Modular Multi-Group Sewing
1. Support Transmission System
When vehicles speed over the expansion and contraction mechanism, they generate vertical and horizontal forces. The central beam of this mechanism is securely anchored on a crossbeam spanning the primary spacing. Together, they form a comprehensive force-bearing unit, efficiently channeling reaction forces to the device's edges while allowing for free movement in sync with the bridge deck's expansion and contraction.
2. Elastic Control System
The sliding interface between the crossbeam and pressure bearings ensures seamless operation. Through precise spring control, the expansion device adeptly handles continuous structural deformation while maintaining uniform gaps. For seam widths exceeding 35mm, the sealing tape can be conveniently replaced without causing any structural damage.
3. Waterproofness
Our expertly crafted sealing rubber strip not only seals gaps between steel beams but also flexibly adapts to the structure's expansion and contraction. The tightly integrated seal between the rubber strip and steel profile groove ensures durability and resistance to detachment.
