Description
Technical field
It is used for civil engineering bridge technology field the present invention relates to one kind, is more particularly to a kind of steel pipe web prestress steel
Mixed combination main beam structure and construction method.
Background technology
During bridge is highway, railway, urban road and road and water conservancy construction, in order to across various obstacles (such as river
Stream or other structures) works.By structure type, bridge can typically divide beam bridge, arch bridge, cable-stayed bridge and suspension bridge；By being used
Material type, bridge generally can be divided into wooden bridge, masonry bridge, reinforced concrete bridge, steel bridge, steel-concrete combined structure bridge etc..
Beam bridge be using by the girder based on curved as supporting member bridge.Girder can be solid web girder or girder truss.Steel
Mixed combining structure beam bridge is by steel and two kinds of concrete girder material of different nature, a kind of combined novel bridge
Structure type.The tensile property of steel and the compressive property of concrete are taken full advantage of due to such bridge, steel can be significantly improved
The mechanical property and raising economy of structure, and there are easy construction, handsome in appearance, environmental protection and energy saving, therefore increasingly
It is widely used in bridge engineering construction field.
Traditional steel concrete combining structure beam bridge is typically using concrete slab and plate girder, steel box-girder or steel truss
The mode that beam is combined.Because the deadweight of real abdomen steel reinforced concrete combination beam (steel plate combination beam, composite beam of steel box) is lighter, real abdomen steel plate is easily
By Wind effects；Empty stomach steel reinforced concrete combination beam (steel truss combination beam) is without the traditional prestressed concrete beam bridge of the image of Buddha, top, bottom plate
Apply prestressing force in concrete to resist dead load and mobile load, therefore span ability is by larger limitation；Traditional girder steel assembling construction
When, cantilever construction is more difficult, and need to set up floor stand is used for the assembled temporary support of girder steel.Thus on the whole, traditional steel reinforced concrete
Coagulating the main deficiency of local soil type's conjunction structure beam bridge is：(1) poor (2) the empty stomach steel reinforced concrete combination beam of real abdomen steel reinforced concrete combination beam wind loading rating is pre-
Stress applies difficult, and span ability is complicated by limitation (3) construction, and construction site takes larger.
So under this background, a kind of satisfaction of exploitation possesses bigger span ability and construction is more convenient, new
Steel pipe web prestressing force steel-concrete combined structure beam bridge structure form, has great practical value.
