Abstract
The utility model provides a convenient, the rational in infrastructure a steel case roof beam that is used for space curved surface rack crooked of preparation, its cross section is rectangle, it including lie in inboard flange plate, lie in the outside outer flange plate, lie in the upper end last shrouding, lie in the lower shrouding of lower extreme, interior flange plate and outer flange plate are respectively some of polygon periphery of the formation by the welding of polylith plain plate.
Description
Technical field
The utility model relates to steel box-girder.
Background technology
Some large stadiums at present, usually adopt the large space curved surface rack of modern design uniqueness.
These large space curved surface racks melt arc component, and space truss is in one, and moulding is complicated.For bending H profile steel, steel box-girder, swan-neck truss that large space curved surface rack uses, how application of advanced technique, for reduce fabrication error as far as possible, producing up-to-standard product is a difficult problem.
Summary of the invention
The purpose of this utility model is to provide a kind of steel box-girder bending for space curved surface rack easy to prepare, rational in infrastructure.
The steel box-girder bending for space curved surface rack described in the utility model, its cross section is rectangle, it comprises the frange plate being positioned at inner side, the outer frange plate being positioned at outside, is positioned at the upper sealing plate of upper end, is positioned at the lower shrouding of lower end, and interior frange plate and outer frange plate are a part for the polygonal outer periphery being welded by polylith plain plate and formed respectively.
Above-mentioned steel box-girder, it also comprises multiple internal partition, the periphery of internal partition respectively with interior frange plate, outer frange plate, upper sealing plate, lower seal plate welding.
Above-mentioned steel box-girder, upper sealing plate and lower shrouding are all plurality of steel plates welding.
Above-mentioned steel box-girder, the soldered of the soldered of upper sealing plate and the soldered of interior frange plate, outer frange plate staggers mutually, and the soldered of the soldered of lower shrouding and the soldered of interior frange plate, outer frange plate staggers mutually.
The beneficial effects of the utility model: the utility model adopts the little plain plate of size to be welded into the interior frange plate of approximate arc, outer frange plate, eliminate the conventional method adopting rolling depression method large-sized long steel plate to be pressed into frange plate in arc, outer frange plate, be convenient to the long distance transportation to plain plate, the Assembling to steel box-girder can be accomplished.Upper sealing plate and lower shrouding adopt Plate Welding, are convenient to equally, to the transport of steel plate, be convenient to Assembling.Internal partition further enhances the intensity of steel box-girder, ensure that bearing capacity.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the steel box-girder bent for space curved surface rack;
Fig. 2 is the enlarged cross sectional views of Fig. 1.
Detailed description of the invention
See the steel box-girder bending for space curved surface rack shown in Fig. 1,2, its cross section is rectangle, it comprises the frange plate 1 being positioned at inner side, the outer frange plate 2 being positioned at outside, is positioned at the upper sealing plate 3 of upper end, is positioned at the lower shrouding 4 of lower end, and interior frange plate is a part (approximate arc) for the polygonal outer periphery being welded by polylith plain plate 11 and formed.Outer frange plate is a part (approximate arc) for the polygonal outer periphery being welded by polylith plain plate 21 and formed.Upper sealing plate 3 almost fan, is welded by polylith plain plate 31 and is formed.Lower shrouding 4 almost fan, is welded by polylith plain plate 41 and is formed.
It also comprises the internal partition 5 of multiple basic rectangularity, the periphery of internal partition respectively with interior frange plate, outer frange plate, upper sealing plate, lower seal plate welding.
The soldered of the soldered of upper sealing plate and the soldered of interior frange plate, outer frange plate staggers mutually, and the soldered of the soldered of lower shrouding and the soldered of interior frange plate, outer frange plate staggers mutually.
