Army Bridge Hebei most professional manufacturer of bridge expansion joints May ex-factory supply, bridge expansion joints, expansion joints, rubber expansion joints, Modular expansion joints, expansion devices, bridges telescopic device, GQF-C, GQF-D, GQF -F, GQF-E, GQF-Z, GQF-L, GQF-MZL joints Installation Notes a telescopic device length due to transport limitations, can be segmented manufacturing, field splicing. Stored at the site of the telescopic device should be placed in parallel, not cross-stacked, to prevent deformation. 2 factory, just connect fixtures designed for easy transport, the gap is not a given location. When installing telescopic device should only be carried out under the supervision of engineers recognized. As specified on the design file to the file specified in the bridge design is based. 3 telescopic device before hoisting concrete tank should be set aside to fight hair, cleaned. When installing telescopic device along the width of a value to the bridge, called on to deal with the gap expansion joints, and make it the top surface elevation and the design elevation anastomosis pad level, and then put the balance to wear reinforced connection level, the telescopic device The anchor bars and beam weld reinforcement embedded on both sides (to maximize the length of weld and welding to extend the life of telescopic device), relax fixtures to free expansion, this time stretching device has entered the state.
