The cold forcing frame has a base (1) which is fitted in a framework (5). The four side walls (2) are fitted with their edges in corner posts (6). The legs (4), which consist of angle iron, are welded onto the base framework (5) or onto the corner posts (6), which likewise consist of angle iron. In this way, the cold forcing frame is raised to the desired height above the ground surface or another support. <IMAGE>
