At the above-mentioned defective of prior art, the present invention to solve in the existing freight container because of adopt C font bottom cross beam higher as the not high enough tradition of the support stiffness that support beam brought the splicing seams of floor under " worker " font bottom cross beam cost, and steel that need be thicker and special hard wooden floor could satisfy the problem that support performance requires.

For solving the problems of the technologies described above, the freight container among the present invention comprises underframe and the floor that is layered on the described underframe; Comprise two foundation curb girders and many foundation crossbeam in the described underframe; Described bottom cross beam is made up of end face, vertical surface and bottom surface; In described each foundation crossbeam, have at least the end face of a foundation crossbeam to form by left end face that lays respectively at described vertical surface and arranged on left and right sides and right end face; Constituting the cross section between described left end face, right end face, vertical surface and the bottom surface is The structure of font.During assembling, be provided with in each bar bottom

The splicing seams place, floor of font crossbeam, the floor in left side are overlapped on the described left end face, and the floor on right side then is overlapped on the described right end face.

Among the present invention, described Can be structure as a whole between the left end face of font bottom cross beam, right end face, vertical surface and the bottom surface.Also can be to be structure as a whole between end face in left end face or the right end face and described vertical surface and the bottom surface, another end face then be installed on the described vertical surface by riveted joint, screw connection, bolted connection or welding manner.Adopt the method for welding in this way, then weld seam has only 2, is half of the I-beam section of traditional fabrication.

Among the present invention, described floor can be a wood covering, also can be in veneer sheet, plastic flagstone, steel-plastic plate or the steel plate any.

Among the present invention, owing to adopted The font bottom cross beam is as the support beam at floor splicing seams place, make the floor of both sides can be overlapped on left end face and right end face respectively, thereby can be on the cooresponding basis of material cost, make bottom cross beam significantly improve to the support stiffness of container floor, and can reduce requirements for quality to container floor, significantly improve freight container service life of container floor particularly.
