Background technology
Current setback shape steel web prestressed concrete combined box beam bridge reached more than 170 meters across footpath, the height of setback shape steel web is more than 8 meters.At this moment, the buckling stability of setback shape steel web becomes a key issue.The practices well of current solution setback shape steel Buckling of Web stability increases thickness of slab and wave height to improve the stability of setback shape steel web, but its effect is quite limited, and establish concrete method in adopting, namely on setback shape steel web surface, pin is welded, then concreting, effectively can improve resistance to compression and the shearing resistance buckling strength of setback shape steel web, and part maintains the feature of the fold effect that setback shape steel plate has.
Summary of the invention
Technical problem: in order to overcome the deficiencies in the prior art, the invention provides a kind of steel-concrete combined structure setback shape steel web, there is very strong resistance to compression and shearing resistance buckling strength, and part maintains the feature of the fold effect that setback shape steel plate has.
Technical scheme: a kind of steel-concrete combined structure setback shape steel web of the present invention, comprise hollow setback shape steel web and interior filling concrete, interior filling concrete is positioned at the groove of hollow setback shape steel web; Described groove is surrounded by the first foldable plate, bias plate and plain plate, and pin is positioned at the survey of the first foldable plate, bias plate, and perpendicular floor is positioned on the second foldable plate.
Be respectively equipped with top flange steel plate and bottom flange steel plate at hollow setback shape steel web top and bottom, top flange steel plate have strip perforate, and be provided with WELDING STUDS.
Top flange steel plate is provided with concrete flange plate.
Be respectively equipped with hole in hollow setback shape steel web upper and lower, in hole, run through plain bars.
Concrete flange plate and lower concrete flange plate is provided with respectively in the upper and lower part of setback shape steel web.
Beneficial effect:
1, the present invention by welding vertical floor on setback shape steel plate, effectively improves the shearing resistance buckling strength of setback shape steel plate;
2, the present invention by being welded with pin in the cavity of plain plate, foldable plate not with ribbing and both sides bias plate formation, and filling has concrete, effectively improves the steel plate resistance to compression of setback shape and shearing resistance buckling strength.
