Description

Technical Field

[0001] The utility model belongs to the technical field of shelves, and particularly relates to a heavy-duty shelf. Background Art

[0002] Traditional heavy-duty shelves usually include several groups of column components arranged in the left-right direction. Several groups of storage platform components are arranged in the height direction between adjacent column components. Each group of column components includes two symmetric columns arranged in the front-back direction. The storage platform component includes a support frame and a storage iron net placed on the support frame. The support frame includes two parallel crossbeams, and several braces are vertically arranged between the two crossbeams.

[0003] Currently, the braces usually adopt two structural forms. The first is a U-shaped structure with the opening facing downwards. The two ends of the top plate of the U-shaped structure are bent downwards for plug-in cooperation with the crossbeam. It is easy to bend downwards when bearing weight, and the load-bearing effect is poor. The second is a U-shaped structure with the opening facing left or right. The two ends of the parallel upper and lower sides are bolted to the crossbeam. Since the open end of the U-shaped structure lacks corresponding support, the load-bearing effect is also poor.
