<p>The invention principally relates to a method of forming a closed metal frame unit (2), with a number, at least three, of coordinated metal frame parts (4a, 4b, 4c), with metal profiles (5a', 5b', 5c') adapted to extend between and be fixedly connected to opposing metal frame parts, while the metal frame parts and the metal profiles rest against an assembly table (1). The invention is based on: a. positioning one or more, metal frame parts (4a, 4b) formed with "L" or "U" cross section, on the assembly table (1) with an orientation corresponding to a part of the periphery of a closed metal frame (2'), b. positioning a number of metal profiles (5a', 5b') in a direction towards a metal frame part, or metal frame parts, where each one of these metal profiles is given a length which corresponds to a distance between opposing metal frame parts (4a, 4c), c. positioning one or more of the remaining metal frame parts (4f, 4g, 4h) against said assembly table (1) for forming the closed metal frame (2') and surrounding said metal profiles (5a', 5b'). The invention especially suggests. d. activating power generating means (90, 91) in order to be able to urge the metal frame parts against the end surfaces (5c'a, 5c'b) of the metal profiles, in order to form said closed metal frame (2') and e. fixedly connecting the diverging end surfaces of the metal profiles (5a', 5b', 5c') to adjacent metal frame part and fixedly and flexurally rigidly connecting the mutually facing end surfaces of the metal frame parts, or vice versa.</p> |
