Abstract
The utility model relates to a prestressed-concrete simply-supported whole-hole box beam, which aims to enable the line of a bridge structure to be more attractive. The prestressed-concrete simply-supported whole-hole box beam comprises an upper web plate (21), a lower web plate (22), a left web plate (11) and a right web plate (12), wherein the upper web plate (21) and the lower web plate (22) are mutually parallel, the left web plate (11) and the right web plate (12) are fixedly connected with the upper web plate (21) and the lower web plate (22), the left web plate (11) and the right web plate (12) are inclined relative to the upper web plate (21) and the lower web plate (22), and the intersected parts of the left web plate (11) and the right web plate (12) as well as the upper web plate (21) and the lower web plate (22) are in circular-arc transition.
Description
Technical field
The utility model relates to prestressed concrete freely-supported whole opening box girder form of structure.
Background technology
Prestressed concrete freely-supported whole opening box girder structurally is made of epiplastron, bottom web, left web and right web.Straight web box girder form is mainly adopted in pre existing prestressed concrete freely-supported whole opening box girder cross section, and there are comparatively stiff, the heavy deficiency of outward appearance in promptly left web, right web perpendicular to epiplastron, bottom web.
The utility model content
Technical problem to be solved in the utility model provides a kind of prestressed concrete freely-supported whole opening box girder, can make the bridge construction lines more attractive in appearance.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
Prestressed concrete freely-supported whole opening box girder of the present utility model, comprise the epiplastron, the bottom web that parallel, and fixed with it left web, right web, it is characterized in that: described left web, right web tilt with respect to epiplastron, bottom web, are arc transition with epiplastron, bottom web intersection.
The beneficial effects of the utility model are, compare with traditional straight web box girder form, can make the bridge construction lines more mellow and fuller, smooth and easy, attractive in appearance, are specially adapted to the area that view is had relatively high expectations.Be mainly used in the high-speed railway bridge simply supported beam, be specially adapted to standardization in enormous quantities and make.
Description of drawings
This manual comprises as next width of cloth accompanying drawing:
Fig. 1 is the cross-sectional drawing of the utility model prestressed concrete freely-supported whole opening box girder.
Component shown in the figure, toponym and pairing mark: left web 11, right web 12, epiplastron 21, bottom web 22.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, prestressed concrete freely-supported whole opening box girder of the present utility model comprises the epiplastron 21, the bottom web 22 that parallel, and fixed with it left web 11, right web 12.Described left web 11, right web 12 tilt with respect to epiplastron 21, bottom web 22, are arc transition with epiplastron 21, bottom web 22 intersection.Can make the bridge construction lines more mellow and fuller, smooth and easy, attractive in appearance, be specially adapted to the area that view is had relatively high expectations.Be mainly used in the high-speed railway bridge simply supported beam, be specially adapted to standardization in enormous quantities and make.
Some principles of the above the utility model prestressed concrete freely-supported whole opening box girder that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
