Product Description

Product Introduction
Description:
Our modular multi-group joints are masterpieces of engineering, designed to offer a multitude of benefits. These include an intricately crafted structure, outstanding expansion and contraction capabilities, top-notch waterproofing, visually appealing aesthetics, formidable strength, prolonged lifespan, and straightforward installation and maintenance. Each joint group caters to a displacement range of 0-80mm, providing the flexibility to customize the groups to match the bridge's specific displacement needs. Typically, the expansion and contraction range spans an impressive 160 to 2000mm.
The Main Working Principle of Modular Multi-Group Sewing
1. Support Transmission System
As vehicles pass over the expansion and contraction device at high speeds, they generate both vertical and horizontal forces. The device's central beam is strategically installed on a supporting crossbeam that spans the main spacing, together forming a highly robust force-bearing structure. This innovative design ensures that the reaction forces are seamlessly transmitted to the edge of the expansion and contraction device, while allowing it to move freely in sync with the bridge deck's expansion and contraction displacement.
2. Elastic Control System
The interface between the supporting crossbeam and the pressure-bearing surface is a meticulously designed sliding interface. Utilizing the force of the spring, the expansion device skillfully adapts to the bridge's ongoing deformations while maintaining consistent gaps. Furthermore, when the seam width surpasses 35mm, the sealing tape can be effortlessly replaced without inflicting any structural damage.
3. Waterproofness
Our precisely engineered sealing rubber strip excels at sealing gaps between steel beams and adeptly accommodates the structure's expansion and contraction variations. The beam end of the sealing rubber strip is securely embedded into the groove of the steel profile, ensuring a tight fit that remains firmly in place.
