The invention discloses a cross-penetrating fixed steel lattice plate comprising M first flat bars, N second flat bars and four side bars. The middle of each flat bar is evenly provided with N through holes including elongated holes and sector holes communicated with each other. The top of each second flat bar is evenly provided with M notches. The first flat bars are evenly arranged, and the through holes in the first flat bars are in one-to-one correspondence according to positional relation. The second flat bars transversely penetrate the elongated holes of the first flat bars and rotate along the sector holes to allow the notches of the second flat bars to be locked in the through holes of the first flat bars. The tops of the first flat bars and the tops of the second flat bars are in a same horizontal plane. The second flat bars penetrate the two first flat bars on two sides. The side bars enclose the first flat bars and the second flat bars and are fixedly welded to the first flat bars and the second flat bars in a one-to-one correspondence manner. The first flat bars and the second flat bars are fixedly connected in a cross-penetrating manner, and the cross-penetrating fixed steel lattice plate is high in bearing capacity and long in service life.
Description
technical field [0001] The invention relates to the technical field of steel gratings, in particular to a cross-interspersed fixed steel grating. Background technique [0002] In the prior art, the steel grating includes pressure-bearing flat steel and twisted square steel. The twisted square steel is placed on a plurality of load-bearing flat steels arranged at predetermined intervals, and the twisted square steel is pressed into the Obtained from flat steel, the structural stability and strength of the steel grating are extremely high, and it is widely used in the industrial field. 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 . During the manufacturing process of the steel grating, the twisted square steel is pressed into the flat...
