ABSTRACT:
The invention relates to a set of components used for producing a load-bearing structure for gratings, comprising pillars and support beams which are removably connected to the pillars via couplings. Flat network-type supporting frames of variable sizes can be formed by using couplings that preferably comprise four connecting elements which are arranged in a cruciform manner for the corresponding connecting elements of the supporting beams. A vertical space can be created between two supporting frames by means of spacers that are disposed on the pillars.
