Expansion joint has complete model and mainly includes GQF-C,GQF-F,GQF-Z,GQF-E,GQF-RG model, GQF-L model and GQF-MZL numerical model bridge expansion joint ,which is a bridge expansion joint device designed by hot-rolled, integral moulding special-shaped steel. Among this ,the GQF-C model, GQF-F model, GQF-Z model, GQF-E model, GQF-RG model and GQF-L model expansion joint are suitable for bridge joint, the expansion amount of which is below 80mm .
TGQF-MZL model is a modular pattern bridge expansion device ,which is composed of edge beam, middle beam, beam and linkage structure . It is suitable for large and medium span bridge, the expansion amount of which is between 80mm-1200mm.
Requirements for expansion joints:
It required that expansion joints can be flexible, firm and reliable ,smooth and no sudden jump and noise when vehicle running on it in two directions :parallel and perpendicular to the axis of the bridge; it also can prevent rainwater and waste soil from infiltration and obstruction; it also shall be easy for installation, inspection, maintenance, and dirt elimination . When set expansion joints, railings and bridge deck pavement should be disconnected.
Range of application of sizing material :
a. When use neoprene (CR) expansion device, it is suitable for areas ,the temperature of which is between -25 ºC to-60 ºC.
b. When use natural rubber (NR) expansion device, it is suitable for areas ,the temperature of which is between -40 ºC- 60 ºC.
I. Rubber is elastic, easy to paste, could meet the requirement of deformation and has water
2. The structure is simple, installation is easy, reliability, comfortable and durability. Easy to re
Place the old expansion and contraction joint, also could be used for the new bridge
3. Good waterproof performance, shock absorption, not sensitive to the construction error of the
Beam-end clearance, long service life, automatic cleaning the inside seam rubbish, less mainte
Nance and low cost
Suitable for the bridge construction project of high-grade highways and urban main road.
