Description
Technical field
The utility model relates to bridge construction technology fields, in particular to a kind of Composite Steel-Concrete Bridges structure
And combined bridge deck.
Background technique
In existing highway bridge structure, traditional Orthotropic Steel Bridge Deck mainly includes top plate, longitudinal rib, diaphragm plate, tradition
Orthotropic Steel Bridge Deck be easy to appear local stiffness deficiency, the problems such as fatigue is prominent, and pave-load layer is easy to damage.It is examined based on above-mentioned
Consider, the prior art is provided with concrete on conventional orthogonal opposite sex steel bridge deck, is connected by connector therebetween
Achieve the effect that common stress, so that crucial tired damageable zone stress collection intermediate range be effectively reduced by increasing bridge floor panel stiffness
Degree, to achieve the purpose that improve Orthotropic Steel Bridge Deck fatigue cracking and deck paving rapid wear problem.But it is above-mentioned existing
Technology is that all kinds of structure sheafs, the weld seam position and tabula of top plate and longitudinal rib are directly arranged on conventional orthogonal opposite sex steel bridge deck
Plate and the connecting portion of longitudinal rib etc. are still to be easy to appear cracking.
Concrete box girder is one of most common structure type of bridge, with biggish bending and torsion stiffness.But with
The increase of bridge span, the self weight of concrete box girder can increase sharply, limit its application on Longspan Bridge, use
Steel-concrete combined structure is one of the effective way for reducing bridge self weight.Nowadays, there are mainly three types of the steel-concretes of type
Combined bridge structure: steel concrete combined bridge front panel and girder steel, top, lower concrete plate and steel web (or steel truss) beam,
And steel concrete combined bridge front panel, steel truss and bottom concrete filled steel tube.The top is wherein used to be for concrete slab, lower part
The combined bridge of truss can substantially reduce bridge self weight, but this structure contains a large amount of panel point, these nodes
Fatigue and stress are concentrated so that the bending resistance of bridge is not fully utilized, so as to cause total global failure.
Therefore, at present how guarantee bridge lightweight, it is high-strength on the basis of reduce weld seam from the root and make full use of
The bending resistance of beam is problem in the urgent need to address in current steel-concrete composite beam bridge design.
Utility model content
The main purpose of the utility model is to provide a kind of Composite Steel-Concrete Bridges structure and combined bridge deck, with
Solve the problems, such as Orthotropic Steel Bridge Deck fatigue cracking in the prior art and deck paving rapid wear.
