Abstract
Abstract 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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
134 words
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.
Claim 2
Dependent Claim
134 words
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.
Claim 3
Dependent Claim
58 words
A means for releasably rigidly fastening two metal beams intersecting at an angle and lying one upon another as claimed in claim 1 wherein said outer faces of said sides of said L-shaped member are respectively provided with two or more vertical ribs so as to protrude orthogonally thereto, and said grooves are formed transversely in said ribs.
Claim 4
Dependent Claim
57 words
A means for releasably rigidly fastening two metal beams intersecting at an angle and lying one upon another as claimed in claim 1 or 2 wherein when said metal beams intersect substantially at right angles two pairs of said L-shaped members are provided, whereby each of said pairs comprises two of said L-shaped members of identical configuration.
Claim 5
Dependent Claim
36 words
A means for releasably rigidly fastening two metal beams intersecting at an angle and lying one upon another as claimed in claim 1, 2 or 3 wherein said fastening means is a nut and bolt assembly.
