Product Description
Bridge Expansion Joint, Modular Expansion Joint
Features:
1, Sturdy and reliable
Crafted with precision, the side beams and middle beams of this expansion joint utilize rolled 16Mn steel, designed to endure the vertical load of high-traffic, heavy vehicles, as well as horizontal impacts. The robust anchoring members, firmly welded to the embedded steel of the bridge deck, ensure that vehicular loads are securely transferred to the abutment. This results in a structure that is not only durable but also built to withstand design loads up to steam - over 20, and hanging - 120 of the bridge.
2, Sensitive expansion
The displacement control system of this advanced device integrates elements such as rubber springs, PTFE pressure bearings, and inclined support members. These components work harmoniously to offer uniform displacement with minimal friction during both expansion and contraction phases, ensuring smooth operation.
3, Smooth bridge deck, comfortable traveling
Designed to allow free expansion and contraction displacement of the beam, this device ensures that the bridge deck joints create a seamless and smooth surface, providing drivers with a comfortable and uninterrupted travel experience.
4, Water stopping and corrosion prevention
Equipped with neoprene rubber sealing strips embedded in the grooves of each steel beam group, this device offers excellent elastic deformation and waterproofing capabilities. These features not only prevent water and dust ingress but also protect the internal components of the expansion joints and the bearing from corrosion, ensuring long-term reliability.
5, Large displacement, convenient selection
Designed with flexibility in mind, the displacement range of this device spans from 80 to 1200mm, based on the modulus. This allows bridge design and construction departments the freedom to select the most appropriate size according to the actual expansion and contraction needs of the bridge superstructure.
Telescopic resistance:
Single-seam expansion joint
1, The compression force is 0.1KN/m during contraction.
2, The longitudinal shear force within the operational range of the expansion joint is 2.0KN/m.
Multi-seam expansion joint
1, The compression force during contraction is 0.1KN/m
2, The tensile force during stretching is 4.0KN/m.
