<p>The parallelepipedic or cubic shaped casing frame is formed by supports (2), which are interconnected in the angles of the casing by means of angle elements (8). Struts (3) may be arranged between the supports (2). Between the supports (2) or optionally between the struts (3), wall plates (4) are fixed. These wall plates (4) are fixed on air-tight profiles (15) by their inner face, these profiles being held by grooves (14, 19) in the supports (2) or optionally in the struts (3). The wall plates (4) are pressed against these profiles (15) by means of rod-shaped support elements (23). The support elements (23) have an L-shaped cross-section and are engaged with one of the branches (23b) in a recesst (10, 10", 20, 20") in the supports (2) or optionally in the struts (3). The support elements (23) are held in a tightening position by means of string-shaped safety members (27) inserted from the outer location of the casing between the supports (2), optionally the struts (3) and the support elements (23); in their tightening position, the support elements are prevented from falling out of the recesses (10, 10", 20, 20"). By spacing the safety members (27), the support elements (23) and then the wall plates (4) may be removed. </p> |
