As long as can play the role of increasing contact surface.
Preferably, the T-steel beam is that whole rolled steel plate-girder is formed along cutting wire cutting, the entirety rolled plate
Beam can be I-beam, H-type beam or T-type beam.
Preferably, the cutting line is broken line or spline curve, is also possible to other special-shaped curves, such as straight line and curve
The cutting line mixed.
Preferably, the cutting line being equidistant apart from described whole rolled steel two flange plates of plate-girder, at this point, one
Whole rolled steel plate-girder can be cut into two the same T-steel beams, not only save material, but also apply convenient for subsequent
Work.Certainly, if apart from not equal and feasible, as long as the T-steel beam can be cut into.
Preferably, the T-steel beam uses weathering steel, is not necessarily to coating, and energy anti-corrosion shortens the construction time, saves construction
Cost, the mountain area especially suitable for execution conditions difficulty.
Compared with prior art, the utility model has the beneficial effects that
(1) the utility model adds concrete by the way that web to be split as to the web one of steel and the web two of concrete
Web two can effectively increase deck-molding, solve the problems, such as that conventional steel plates depth of beam is insufficient, the rigidity of the bridge of large span in satisfaction
With bending resistance requirement.
(2) web one of the utility model T-steel beam and flange plate one eliminate original welded connecting form, are changed to adopt
With whole roll forming, fillet weld is eliminated, avoids adverse effect of the fillet weld to structure stress.
(3) the utility model is in the join domain of steel and concrete, and also eliminating traditional connector, (such as bolt is cut
Power nail etc.), lower concave part and upper convex portion are directly processed on the web one of T-steel beam, are formed tooth-shape structure, are increased T-steel
The contact surface of beam and concrete slab, concrete slab carry out cast-in-place filling, the lower concave part and upper convex portion insertion to the lower concave part
In the web two, engagement effect is formed, to realize effective connection of T-steel beam and concrete slab, such connection type
Not only bonding strength is high, and can avoid the fatigue problem of connector.
(4) the utility model also eliminates the top flange plate of traditional steel-concrete connecting beam light plate beam, more than neutral axis
Compressive region use concrete material, and neutral axis tensile region below uses steel construction, takes full advantage of material property, saves
Steel using amount.
