Description

[Detailed description of the invention] The present invention relates to an improvement in a prefabricated steel shelf.

Conventional prefabricated steel shelves consist of frames made by welding the front and rear supports together using horizontal and diagonal members, which are arranged side by side at a fixed distance in the left and right direction of force, and a loading beam is erected between each frame. There are two types: those that are fixed, and those that connect columns, horizontal members, diagonal members, load receiving beams, etc. with bolts and nuts.

By the way, the former prefabricated steel shelf has a rigid structure in which the frames on both the left and right sides cannot be disassembled, so the packaging during transportation is large and shipping costs are extremely high. be.

In addition, special metal fittings are required at both ends of the load receiving beam to erect and fix it to the frame, and since the erecting and fixing position of the load receiving beam is fixed at a fixed position, the shelf height can be adjusted according to the shape of the cargo to be loaded and stored. It is impossible to adjust.

In addition, the latter type of prefabricated steel shelves are assembled by connecting all the parts with bolts and nuts, which requires a great deal of labor and time to assemble and disassemble, resulting in extremely poor work efficiency. be.
