1. A method for constructing a museum display case comprising a platform and a case above the platform, the case having at least one opening door, the method comprising:
applying first metal beams comprising a tubular structure to glass panes by gluing, forming wall units;
providing second metal beams comprising a tubular structure at the at least one opening door;
providing L-shaped corner joints, each L-shaped corner joint having only two arms;
forming the case by assembling the wall units together by the first metal beams, the second metal beams, and the L-shaped corner joints,
wherein the first metal beams applied by gluing to the glass panes and the second metal beams provided at the at least one opening door are fixed together by the L-shaped corner joints to form together a load-bearing structure, and
wherein the first and second metal beams are solely horizontally arranged along the glass panes;
applying a ceiling to the load-bearing structure after the load-bearing structure has been formed by the first metal beams, the second metal beams, and the L-shaped corner joints; and
fixing the load-bearing structure to the platform.
