The utility model belongs to a steel grating, in particular to a composite steel grating with a horizontal bar at the bottom. The problem to be solved exists in the background technology: the welding surface with the checkered plate is discontinuous, which affects the welding strength. And the residual zinc in the gap formed in the galvanizing process affects the appearance. The key points of the technical solution adopted to solve this technical problem are: several horizontal bars are located below the composite steel grating, some flat steels are welded on the tops of the several horizontal bars, and checkered plates are welded on the tops of the several flat steels. The utility model can be applied to manufacture composite steel gratings, and has the remarkable advantages of high welding quality and beautiful appearance.
Description
Technical field: the utility model belongs to steel checkerboard, particularly a kind of cross bar under compound steel checkerboard.
Background technique: the structure of existing compound steel checkerboard: some band steels are positioned at below the compound steel checkerboard, and pressure welding plurality of cross bars above some band steels is welded diamond plate above the plurality of cross bars.Therefore the compound steel checkerboard of this structure forms contacting of discontinuous state with diamond plate because cross bar is higher than the upper surface of band steel, causes with the face of weld of diamond plate discontinuously, influences weld strength.On the other hand, the compound steel checkerboard of this structure forms the entrapped zinc in the gap in zincincation, influences attractive in appearance.
Summary of the invention: the purpose of this utility model be exactly propose a kind of cross bar under the technological scheme of compound steel checkerboard, background technique exists to solve: discontinuous with the face of weld of diamond plate, influence weld strength.And in zincincation, form entrapped zinc in the gap, influence attractive in appearance.Solving this technical problem the technological scheme that is adopted is: a kind of cross bar under compound steel checkerboard, it is characterized in that plurality of cross bars be positioned at compound steel checkerboard below, the some band steels of top welding of plurality of cross bars, the top welding diamond plate of some band steels.Wherein, the plurality of cross bars pressure welding in some band steels within.
The beneficial effect that the utility model is had compared with the prior art is: owing to adopt technique scheme, direct and the band steel upper surface welding of diamond plate, the mating face voidlessness has guaranteed welding quality and intensity, and in zincincation, do not produce entrapped zinc, guarantee that product is attractive in appearance.
Description of drawings: Fig. 1 is the utility model overall structure schematic representation.
