Abstract

The invention discloses a highly-erected steel bar grating. The highly-erected steel bar grating includes multiple flat steel bars (1), multiple twisted square steel bars (2), two enclosing steel bars(31, 32) and two highly-erected pipe fittings (41, 42) with equal heights, wherein each highly-erected pipe fitting (41 or 42) is a rectangular steel pipe or two rectangular steel pipes welded in a top-bottom overlaying mode; the multiple twisted square steel bars (2) are transversely arranged on and fixedly connected in a pressure welding mode with the multiple flat steel bars (1) which are evenly arranged according to preset intervals, the two enclosing steel bars (31, 32) are transversely welded on the two end faces of the multiple flat steel bars (1), and the two highly-erected pipe fittings (41, 42) are each transversely welded on the bottom surfaces of the two ends of the multiple flat steel bars (1). According to the highly-erected steel bar grating, the highly-erected pipe fittings are arranged at the bottom of the steel bar grating, wherein each highly-erected pipe fitting is the rectangular steel pipe or two rectangular steel pipes welded in a top-bottom overlaying mode, sothat installment operation of steel bar CNN20357140703571407U gratings with different installment height requirements is satisfied, and the adaptability of the steel bar grating is improved.

Description

technical field [0001] The invention relates to the technical field of steel gratings, in particular to an elevated steel grating. Background technique [0002] In the prior art, the steel grating includes pressure-bearing flat steel and cross bars, and multiple load-bearing flat steel bars are arranged and welded according to predetermined spacing and cross bars. The structural stability and strength of the steel grating are extremely high. The application in the industrial field is very extensive. Since the steel grating has a square grid structure, its dimensions can be made according to actual application requirements, and it can be square, arc, circular and composite structures. Therefore, the steel grating can meet the application requirements of different application scenarios . In the steel grating design process, in order to save materials, the height of the steel grating is controlled within the predetermined range under the premise of meeting the load-bearing re...
