Description

Rack with improved coupling convenience and construction method thereof

The present invention relates to a rack with improved coupling convenience and a construction method thereof.

A rack for loading or storing goods is composed of a plurality of support columns, a support and a fixed beam connecting the columns, and a shelf plate on which goods are placed.

Conventional racks were mostly assembled by fastening each part using bolts and nuts.

This bolt-nut fastening method has the problem that it takes a lot of time during the assembly process, assembly tools are absolutely necessary, and the threads of the bolts or nuts wear out or are damaged during frequent assembly and disassembly, which reduces the bonding strength.

Additionally, if the bolts are not tightened sufficiently, the overall structural stability of the rack may be reduced, and excessive tightening may cause deformation of the parts.
