Embodiment Construction

[0009] The invention relates to a multi-box single-chamber box girder, which includes a top plate, a bottom plate and webs between the two. The bottom plate and double the number of webs are added, and several box-shaped units are added to the lateral sides of the original box-shaped units.

[0010] The number of added box units can be increased or decreased arbitrarily according to the width of the top plate.

[0011] The web is corrugated steel web.

[0012] By adding box-type units, the box girder can still ensure sufficient bearing capacity when the overall width is increased; and the corrugated steel web has the characteristics of light weight and high rigidity, which is convenient for construction.

[0013] The invention discloses a multi-box single-chamber box girder. The structure of the box girder is changed, and the bearing capacity of the box girder is increased by adding box-type units.

[0014] Finally, it should be noted that: the above is only a preferred embod...

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 [0001] The invention relates to a multi-box single-chamber box girder, which belongs to the field of bridge engineering. Background technique [0002] With the rapid development of transportation and the acceleration of urban modernization, bridge construction is becoming more and more important in the increasingly busy highways and the rapid development of urban transportation. At present, the most widely used in bridge construction is the box girder, which has the characteristics of firm structure, strong bearing capacity, and durability. However, for some bridges with wide road surface, ordinary box girders cannot meet the load-bearing requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects, provide a multi-box single-chamber box girder, change the structure of the box girder, and increase the bearing capacity of the box girder. [0004] In order to solve the probl...
