Technical field
The present invention relates to a kind of heterotype steel plate combining structure case beam. Belong to bridge structure field.
Background technology
Highway, high ferro, subway, overhead road of city, rural area bridge adopt xoncrete structure case beam mostly at present, and its complex structure, from great, tensile strength is poor, makes difficulty, and beam field is disposable to have high input, curing time is long, and spanning equipment is expensive, and the security risk of setting up is large.
And employing steel construction or ordinary steel ~ concrete combining structure, not only expensive and because the rigidity of steel plate is inadequate, need to weld a large amount of ribs, not only need to expend a large amount of materials and machinery, welding labour cost, and because the residual stress of welding and the existence of weld heat-affected zone reduce the anti-fatigue performance of structure node, affect the service life of structure.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of heterotype steel plate combining structure case beam is provided, has used the heterotype steel plate forming after clod wash or hot rolling to substitute existing xoncrete structure or steel plate structure, can not only increase substantially the strength and stiffness of steel plate, and the deadweight that has greatly alleviated case beam, reduce the load of case beam substructure, reduce construction costs, simultaneously processing, easy for installation, can batch production produce, shorten construction period, steel waste material recoverable, is beneficial to environmental protection.
The object of the present invention is achieved like this:
A kind of heterotype steel plate combining structure case beam, is characterized in: described heterotype steel plate combining structure case beam comprises top board, base plate, web and diaphragm plate, described top board adopts xoncrete structure, and described base plate, web and diaphragm plate all adopt heterotype steel plate to make.
A kind of heterotype steel plate combining structure of the present invention case beam, the shape of its heterotype steel plate can be grooved, arc, trapezoidal and buttress shape, is made up of separate unit or multiple-unit, and this heterotype steel plate uses the equipment of hot rolling corresponding with its shape or cold bending equipment rolling to form.
Compared with prior art, the invention has the beneficial effects as follows:
1. a kind of heterotype steel plate combining structure of the present invention case beam, its web, diaphragm plate and base plate all adopt heterotype steel plate to make, compared with traditional concrete box girder, effectively resistance to compression bending resistance, and greatly alleviated the deadweight of case beam, the load of minimizing substructure.
2. a kind of heterotype steel plate combining structure of the present invention case beam, not only reduces cost, and processing, easy for installation, can batch production produce, shorten construction period.
3. a kind of heterotype steel plate combining structure of the present invention case beam, compared with the case beam of xoncrete structure, steel are as the green resource that can reuse, and after bridge life stops, steel all reclaim, and have effectively reduced building waste, are beneficial to environmental protection.

Detailed description of the invention
Referring to Fig. 1-8, the present invention relates to a kind of heterotype steel plate combining structure case beam, it comprises top board 1, base plate 2, web 3 and diaphragm plate 4, and described top board 1 adopts prestressed reinforced concrete construction, and described base plate 2, web 3 and diaphragm plate 4 all adopt heterotype steel plate to make.
Described heterotype steel plate shape can be grooved, arc, trapezoidal and buttress shape, formed by separate unit or multiple-unit, the thickness of slab 6-30mm of heterotype steel plate, high 50-300mm, the wide 50-600mm of upper and lower opening, this heterotype steel plate can adopt roll bending to process by hot rolling or clod wash, and the roll of hot rolling or cold bending equipment is corresponding with the shape of heterotype steel plate.
Described heterotype steel plate also can be applicable to pier stud, and heterotype steel plate is as the wallboard of pier stud.
Described heterotype steel plate can be widely used in the prefabricated or cast-in-situ box girder of high ferro, subway, highway and city, rural area bridge superstructure, and heterotype steel plate is as web, base plate and the diaphragm plate of case beam, and floorings can be xoncrete structure.
Described heterotype steel plate also can be applicable to the wallboard of head tower structure.
The beam being made up of sketch plate or post can be formed by single sketch plate unit or multiple sketch plate unit combination, also can with steel plate, concrete composition combining structure, if adopt high performance high-strength steel, weathering steel, even stainless steel the combination property of heterotype steel plate is more superior.
