Product Description
Bridge Expansion Joint, Modular Expansion Joint
Futures:
1, Sturdy and reliable
The side beams and middle beams of this expansion joint are made of rolled 16Mn steel, which can withstand the vertical load of large flow and large tonnage vehicles and horizontal impact. Its anchoring members with beams, bridge deck of the embedded steel welded firmly, the vehicle load can be reliably transferred to the abutment, structurally sound, durable, applicable to the design load steam - over 20, hanging - 120 of the bridge.
2, Sensitive expansion
The displacement control system of this device consists of spring elements such as rubber springs, PTFE pressure bearings or inclined support members, with uniform displacement and small friction of expansion and contraction in each group.
3, Smooth bridge deck, comfortable traveling
This device can not only ensure the free expansion and contraction displacement of the beam, but also make the bridge deck joints form a smooth whole, driving smoothly and comfortably.
4, Water stopping and corrosion prevention
The neoprene rubber sealing strip embedded in the groove of each group of steel beams. According to the bridge width of the whole processing, with good elastic deformation and waterproof and dustproof function; can effectively protect the internal components of expansion joints and sorghum bottom bearing from erosion.
5, Large displacement, convenient selection
The displacement of this device is designed and manufactured according to the modulus, from 80 to 1200mm. bridge design and construction departments can choose freely according to the actual expansion and contraction of the bridge superstructure.
Telescopic resistance:
Single-seam expansion joint
1, The compression force is 0.1KN/m during contraction.
2, Longitudinal shear force within the working range of expansion joint is 2.0KN/m.
Multi-seam expansion joint
1, Compression force during contraction 0.1KN/m
2, Tensile force when stretching 4.0KN/m
