Abstract
The utility model discloses a prestressed concrete box girder adopting corrugated steel webs, which solves the problems that material consumption and weight are increased when the bearing capacity of the prestressed concrete box girder adopting the corrugated steel webs is improved in the prior art. The prestressed concrete box girder comprises a box body formed by an upper steel wing plate, a concrete-filled steel tube bottom plate as well as left and right corrugated steel webs, wherein a plurality of inner diaphragm plates are arranged at two ends of the box body and on the inner side of the box body, a plurality of reinforcing supports are connected onto the upper steel wing plate and buried in precast concrete, and the height of each reinforcing support is smaller than the thickness of the concrete; the reinforcing supports are triangular and rectangular; prestressed tendons are arranged in the concrete-filled steel tube bottom plate and anchored on the concrete through an anchorage device; and the cross section of the box body is rectangular and trapezoidal, and shapes of the inner diaphragm plates are matched with the cross section of the box body. With the adoption of the technology, steel is saved, the bearing capacity is improved, and the stability of the bearing capacity is further guaranteed.
Description
Technical field
This utility model relates to a kind of concrete box girder, particularly relates to a kind of Wavelike steel webplate prestressed concrete box girder.
Background technology
At present, Wavelike steel webplate Combined concrete girder construction takes full advantage of concrete anti-compression, Wavelike steel webplate light weight, the advantage that shearing resistance yield strength is high.Due to the axial force of Wavelike steel webplate non resistance effect, the confined concrete wing is not pulled owing to creeping and being dried and is shunk the distortion producing, and has improved the service efficiency of stability, intensity and the material of structure.In order to improve the ability to bear of case beam, simple mode is exactly to improve the thickness of case beam various piece, but also increased material and whole weight simultaneously.
Utility model content
The utility model has overcome in prior art, and Wavelike steel webplate prestressed concrete box girder, when improving supporting capacity, has also increased the problem of material consumption and own wt simultaneously, and a kind of Wavelike steel webplate prestressed concrete box girder simple in structure is provided.
Technical solution of the present utility model is, provide a kind of Wavelike steel webplate prestressed concrete box girder with following structure: the casing that contains steel upper flange, concrete filled steel tube base plate, left and right Wavelike steel webplate formation, in tank ends and inner side, be provided with some interior diaphragms, on described steel upper flange, be connected with a plurality of reinforced supports, it is embedded in precast concrete, and it is highly less than concrete thickness.
Reinforced support is triangle, rectangle.In concrete filled steel tube base plate, have presstressed reinforcing steel, they are anchored on concrete by ground tackle.The cross section of casing is rectangle, trapezoidal, interior diaphragm shape and casing cross section adapt.
Compared with prior art, the utility model Wavelike steel webplate prestressed concrete box girder has the following advantages: saved steel, increased supporting capacity, and guaranteed the stability of supporting capacity.
