BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention concerns a container having profiled wall and roof panels which are secured to each other at the longitudinal edge joints by welded, profiled longitudinal girders.
BACKGROUND
In the known containers (dry cargo) the profiled longitudinal girders are formed by closed profiles, preferably four-sided profiles. When goods are to be transported in the container in a suspended state, the longitudinal girders are provided with rails or profiles for the attachment of cross beams from which the goods hang down.
Only when there is need for transporting suspended goods in the container, is the container provided with said rails or profiles, which are subsequently riveted or welded to the longitudinal girders. This subsequent mounting causes damage to the internal surface finish of the container, and in case of welding also damage to the external surface finish. The subsequent mounting moreover involves additional costs in that the container is to be taken out of service, is to be transported to a workshop in which the subsequent mounting is to be performed, and is then to be sent back to be put into service. The subsequently mounted container is thus often in a poorer state, in particular as regards the surface finish, than the container was beforehand.
SUMMARY OF THE INVENTION
The object of the present invention is therefore to provide a container which is provided with expedient means already during the actual manufacture for the mounting of transverse suspension beams for the goods.
The container of the present invention is characterized in that the longitudinal girders are formed by profiles which are formed integrally with longitudinal, inwardly extending flaps for the subsequent mounting of transverse suspension devices.
Accordingly, there is provided a container which need not to be subsequently equipped with rails or profiles for the mounting of transverse suspension beams, and which is simultaneously both simple and inexpensive to manufacture, since it can be manufactured at the existing production plants.
According to the invention, the profiled longitudinal girders may be provided as "open" profiles so that the longitudinal girders, and thereby the entire container, can be formed without cavities that might contain contraband goods, such as narcotics or the like.
Further, according to the invention, the longitudinal girders may be formed by U-profiles arranged so that the legs of the U extend substantially horizontally, said flaps being formed by the lower leg of the U. The transverse suspension beams, and hereby the suspended goods, may hereby be arranged quite close below the roof panel.
Said flanges may be formed by an extension of one leg of the U in a particularly simple manner.
According to the invention, the longitudinal girders may be formed by other "open" profiles, such as I-profiles, where said flaps are formed by one portion of the lower flange of the I.
Finally, according to the invention, the inwardly directed edge of the flap may be provided with a thickening to retain and control the mounting device of the transverse suspension beam at the end.
BRIEF DESCRIPTION OF THE DRAWING
The invention will be explained more fully below with reference to a particularly preferred embodiment illustrated in the drawing, in which
FIG. 1 is a schematic perspective view of a dry cargo container provided with the longitudinal girders of the invention,
FIG. 2 is a schematic sectional view of a longitudinal edge joint comprising a U-shaped longitudinal girder, and
FIG. 3 is a reduced-scale view of the same with a mounted suspension beam.
DETAILED DESCRIPTION
The dry cargo container shown in FIG. 1 comprises profiled wall and roof panels 2, 3, which are secured to each other at the longitudinal edge joints 4 via welded profiled longitudinal girders 5.
The profiled longitudinal girders may be formed as U-profiles 5 in a particularly expedient manner, arranged so that the legs 6, 6' of the U 5 extend substantially horizontally from the outwardly directed bot
