the setting of continuous seam

According to the design of continuous joint width and span bridge beam (plate) the difference between the length of the design set, 30m combination of T continuous beam width 6cm; various width of 4cm continuous slab; wedge adjustment curve on curve bridge deck set in cap and wedge parts of continuous suture set by two slits and each slot width not less than 4cm, usually the design width of 2cm is small.

Continuous deck joints, deformation pseudomorphism width and depth must be standardized, uniform, seam width and depth are advised by 0.5 - 2.5cm one set, this is convenient for construction.

Extension of the company's production of bridge expansion joint device and a rubber strip type device, suitable for expansion is equal to or less than 50mm below the highway bridge engineering: type BF with plate rubber expansion device, which is suitable for the expansion of highway bridge engineering is less than 200mm, not suitable for highway; ZT-SF comb plate telescopic device is made of steel plate comb after a cross shaped telescopic gap, at the other end of the stainless steel plate, the above expansion amount of up to 40mm, for large, medium span bridge; ZT-GQF-C type (Z type, F type, M type, O type) bridge expansion device for expansion is less than 80mm and Z;T-GQF-MZL type expansion device is a modular bridge expansion device is composed of shaped steel and the linkage mechanism, it is suitable for the expansion of the 80-1200mm bridge expansion device; ZT-XF series is composed of parallel special-shaped steel in bridge joint direction and oblique displacement and supporting box. It is also suitable for expansion in bridge engineering 80-1200mm.
