PURPOSE: To reduce the time for assembling, reduced the cost, and effectively utilize the resourceful refuse by disposing a large number of empty cans or empty containers of synthetic resin between an upper board and a lower board and fixing them by means of bands for packaging.

CONSTITUTION: Supports 3 comprising a large number of empty cans or empty containers 31 of synthetic resin are disposed between an upper board 1 and a lower board 2, both the board 1 and the board 2 having thereon lateral and longitudinal recesses, and both the boards are fixed by means of packaging bands 5 or blind rivets. And the empty containers 31 may be arranged, in a honeycomb structure pattern, in a space between the board 1 and the board 2 excluding an opening for insertion of forks of a fork-lift truck to provide a structure for supporting heavy weights. By this method, since spot welding is not required at the time of assembling, the assembling is performed in a simple manner and the productivity is improved, and reduced cost can be achieved, and further resourceful refuse can be effectively utilized. Moreover, the disposal of the boards can be achieved only by cutting off the bands 5, so that the separated components thereof can be efficiently treated.
