A method and means for releasably rigidly fastening two standardized metal profiles intersected at an angle and lying one upon another are provided in which four L-shaped members each having two vertical sides are respectively applied at the respective corners of the intersection such that the outer faces of the respective sides of the L-shaped member abut against the respective edge portions of the metal profiles at the intersection lying one upon another and at the same time portions of the respective sides are made to protrude beyond the upper or lower surface of the metal profiles, whereby the confronting protruded portions of the sides of the L-shaped members are rigidly connected together by any suitable fastening means with the metal profiles being respectively interposed between the confronting sides, respectively.
A means for releasably rigidly fastening two metal beams intersecting at an angle and lying one upon another, consisting essentially of four L-shaped members each having two vertical sides intersected at one end of each so as to make an angle corresponding to the angle made at the respective corners of said intersection of said metal beams, said sides of each of said L-shaped members being formed on their outer faces with grooves respectively adapted to receive therein the respective edge portions of the lower and upper parts of said metal beams at said respective corners of said intersection, and a number of fastening means adapted to rigidly connect said sides of said L-shaped members protruding above or below said lower and upper parts of said metal beams so as to confront each other.
