Construction device for the assembly of trusses mounting apparatus

摘要

Device construction assembly lattices mounting apparatus, with profiles (1, 2 14), nuts (11, 12) engageable in half-open grooves (5, 6, 7, 15) of the profiles and screws (10) usable with them, which are provided fundamental or frame profiles (1, 2) which have suitable for direct determination of the height of mounting profiles (8, 14) for apparatus (9) and covers (18) slots on a mounting base, and in that the basic profiles (1) have two branches (3, 4) at right angles relative to each other; characterized in that the shorter leg (4) which serves for mounting on the base (40) has a groove (5) open inward transversely of that branch, while the other branch (3) has at its end a slot (6) open out, and within a groove (7), at least open inwards transversely to the branch (3).
