Abstract
The invention provides a multi-box single-chamber box beam which comprises a top plate, base plates and web plates between the top plate and the base plates. The base plates and the doubled web plates are increased, and a plurality of box type units are added on the basis of a horizontal side of an original box type unit. The number of the added box type units can be randomly increased or decreased according to the width of the top plate. The web plates are corrugated steel web plates. The multi-box single-chamber box beam structure is changed, and by adding the box type units, the bearing capacity of the box beam is improved.
Description
Technical field
The present invention relates to a kind of many casees single cell box girder, belong to bridge engineering field.
Background technology
Along with the quickening with urban modernization pace of construction that develops rapidly of communications and transportation cause, in the fast development of day by day busy highway and urban traffic cause, the status of bridge construction is also more and more important.The features such as at present most popular in bridge construction is exactly case beam, and that case beam has is firm in structure, bearing capacity is strong, durable in use.But for the wider bridge in some road surfaces, common case beam cannot reach load bearing requirements.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, and a kind of many casees single cell box girder is provided, and changes box-beam structure, increases the bearing capacity of case beam.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
Many casees single cell box girder, comprises top board, base plate and web between the two, increases the web of base plate and diploidy number amount, and the transverse side in original box unit, adds some boxes unit.
Further, the box unit number of interpolation can increase and decrease arbitrarily according to the width of top board.
Further, described web is Wavelike steel webplate.
A kind of many casees single cell box girder of the present invention, changes box-beam structure, by increasing box unit, has increased the bearing capacity of case beam.
The specific embodiment
The present invention relates to a kind of many casees single cell box girder, comprise top board, base plate and web between the two, increase the web of base plate and diploidy number amount, the transverse side in original box unit, adds some boxes unit.
The box unit number of adding can increase and decrease arbitrarily according to the width of top board.
Web is Wavelike steel webplate.
By adding box unit, make case beam in the situation that integral width increases, still guarantee enough bearing capacities; And the feature that Wavelike steel webplate has is lightweight, rigidity is large, constructability.
A kind of many casees single cell box girder of the present invention, changes box-beam structure, by increasing box unit, has increased the bearing capacity of case beam.
Finally it should be noted that: the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although the present invention is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
