Stepped crossbeam of light goods shelf

Abstract

The invention discloses a stepped crossbeam of a light goods shelf, comprising a bearing surface, and vertical faces which are arranged at the two sides of the bearing surface in a downward extending manner, wherein, the vertical face comprises an outer vertical face and an inner vertical face; the top part of the outer vertical face is higher than the bearing surface; a stepped flange is formed between the top parts of the bearing surface and the outer vertical face; and the inner vertical face gradually inclines to the outer vertical face from the bearing surface, thus leading the bottom projected area to be less than the sum of the projected area of the bearing surface and the top surface of the flange. As the stepped crossbeam of the invention is provided with the flange, the two crossbeams can be arranged on a goods shelf stand column in an opposite direction when in installation; when in paving the laminated panels, the end parts of the laminated panels are blocked and strained by the flanges of the crossbeam, thus the laminated panels are fixed between the crossbeams which are arranged in the opposite direction, thereby avoiding the laminated panels from displacing, and improving the use safety of the goods shelf; and meanwhile, as the inner vertical face is arranged obliquely, the circumference of the cross section is short relative to the crossbeam with a square cross section, thus saving the crossbeam materials.

Description

technical field [0001] The invention relates to the technical field of load-bearing parts of shelves, in particular to a stepped beam of a light-duty shelf. Background technique [0002] The beam is the basic component of the shelf. On the one hand, it connects the column of the shelf to form the frame of the shelf. On the other hand, it is used to lay laminates on the beam for placing goods. [0003] Existing shelf beams are generally made of square tubes, that is, the cross-section of the beam is generally square. This beam includes a bottom surface, two facades, and a bearing surface located on the top surface. Because the bearing surface is flat, when installing the laminate, the laminate is placed on the bearing surface of the beam, and there is no constraint along the direction of the laminate surface, which will easily cause the sliding displacement of the laminate on the shelf, which is not conducive to the fixing of the laminate, and even causes The laminate breaks...

AI Technical Summary

Problems solved by technology

Because the bearing surface is flat, when installing the laminate, the laminate is placed on the bearing surface of the beam, and there is no constraint along the direction of the laminate surface, which will easily cause the sliding displacement of the laminate on the shelf, which is not conducive to the fixing of the laminate, and even causes The laminate falls off the bearing surface and overturns, which brings inconvenience to the use and maintenance of the shelf

[0004] And especially for light-duty shelves, due to the small load-bearing capacity of light-duty shelves, the safety load-bearing requirements of the beams are easy to meet, and the beams with square cross-sections have a long cross-section perimeter, resulting in unnecessary waste of beam materials and increased material costs.
