Abstract
Abstract A device for laterally interconnecting structural members such as beams and columns. The device comprises a plate with a face and a circumscribing edge, at least one slot extending inwardly from the edge and at least one stud extending outwardly from the face of the plate means. Two such plates, one inverted, fixed to a pair of structural members, are interconnected by passing them contiguously and in parallel to have the stud of one plate enter the slot of the other plate. Preferably there are two parallel slots and two studs in the plate means, the closed ends of the slots and the studs forming a rectangle. In an I-column the upper portion of the flange may be used as one plate and below the upper portion of the column the plate may take the form of a bracket.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
68 words
A device for use in interconnecting two structural members, comprising plate means having a planar face and a circumferential edge, at least two parallel slots in the plate means extending from the edge of the plate means, and at least two studs projecting outwardly from the face of the plate means, the studs being arranged to be engagable in the slots of an inverted device of like construction.
Claim 2
Independent Claim
68 words
A device for use in interconnecting two structural members, comprising plate means having a planar face and a circumferential edge, at least two parallel slots in the plate means extending from the edge of the plate means, and at least two studs projecting outwardly from the face of the plate means, the studs being arranged to be engagable in the slots of an inverted device of like construction.
Claim 3
Dependent Claim
42 words
A device as claimed in claim 1 in which the plate means has two of said slots and two of said studs, the slots being parallel one to the other, the closed ends of the slots and the studs forming a rectangle.
Claim 4
Dependent Claim
16 words
A device as claimed in claim 1 in which said plate means comprises a rectangular plate.
Claim 5
Dependent Claim
34 words
A device as claimed in claim 1 in which said stud comprises a bolt having a threaded shank projecting outwardly from the plate means and having a nut threaded on the free end thereof.
Claim 6
Dependent Claim
32 words
A device as claimed in claim 4 in which said bolt has a knurled shank portion adjacent the head thereof, the shank portion being press-fitted into an aperture in the plate means.
Claim 7
Dependent Claim
18 words
A device as claimed in claim 1 in which the slot tapers inwardly from the open end thereof.
Claim 8
Dependent Claim
39 words
A device as claimed in claim 6 in which the stud has a shank trapezoidal in cross-section, the two non-parallel sides of the shanks having planes converging at an angle equal to the angle of taper of the slot.
Claim 9
Independent Claim
146 words
A device for interconnecting two structural members comprising: plate means fixed vertically on one of the members, the plate means having a circumferential edge and a planar face, at least two parallel first slots extending upwardly from the edge of the plate means and at least two first studs projecting outwardly from the face of the plate means; and means on the other member for interengaging with said plate means, said interengaging means having a vertical planar face, at least two parallel second slots extending downwardly from a free upper edge of the interengaging means, and at least two second studs projecting outwardly from the face of the interengaging means, the first two studs being engageable in the second two slots and the second two studs being engagable in the first two slots on moving said one member vertically downward with respect to the other member.
Claim 10
Independent Claim
146 words
A device for interconnecting two structural members comprising: plate means fixed vertically on one of the members, the plate means having a circumferential edge and a planar face, at least two parallel first slots extending upwardly from the edge of the plate means and at least two first studs projecting outwardly from the face of the plate means; and means on the other member for interengaging with said plate means, said interengaging means having a vertical planar face, at least two parallel second slots extending downwardly from a free upper edge of the interengaging means, and at least two second studs projecting outwardly from the face of the interengaging means, the first two studs being engageable in the second two slots and the second two studs being engagable in the first two slots on moving said one member vertically downward with respect to the other member.
Claim 11
Dependent Claim
84 words
A device as claimed in claim 8 in which the plate means has two of said first slots parallel one with the other and two of said first studs, the closed ends of the first slots and the first studs forming a rectangle, and in which the interengaging means on the other member has two of said second slots parallel one with the other and two of said second studs, the closed ends of the second slots and the second studs forming a rectangle.
Claim 12
Dependent Claim
25 words
A device as claimed in claim 8 in which the interengaging means comprises a bracket having a vertical plate portion outstanding from said other member.
Claim 13
Dependent Claim
15 words
A device as claimed in claim 10 in which the bracket comprises a channel member.
Claim 14
Dependent Claim
50 words
A device as claimed in claim 8 in which said one member is an I-beam and said other member is an I-column, said second slot being located in one flange of the column and extending downwardly from the top end thereof, said second stud extending outwardly from said one flange.
Claim 15
Dependent Claim
57 words
A device as claimed in claim 8 in which said one structural member is an I-beam and the upper edge portion of the plate abuts the end of the upper flange of the I-beam, and including a recess located in the lower flange of the I-beam contiguous one with said first slot to pass said second stud.
Claim 16
Dependent Claim
126 words
In a beam interconnectable with another structural member to form a structural unit: a pair of plates each having a planar face and a circumscribing edge, at least two parallel slots in each plate extending inwardly from the edge thereof and at least two studs in each plate projecting outwardly from the face thereof; one of said plates being fixed vertically to one end of the beam with the slots therein opening upwardly and the other of said plates being inverted and fixed vertically to said other structural member with the slots therein opening downwardly; the two plates being interconnectable contiguously and in parallel one with the other on moving said beam downwardly whereby the studs of each plate enter the slots of the other plate.
Claim 17
Dependent Claim
126 words
In a beam interconnectable with another structural member to form a structural unit: a pair of plates each having a planar face and a circumscribing edge, at least two parallel slots in each plate extending inwardly from the edge thereof and at least two studs in each plate projecting outwardly from the face thereof; one of said plates being fixed vertically to one end of the beam with the slots therein opening upwardly and the other of said plates being inverted and fixed vertically to said other structural member with the slots therein opening downwardly; the two plates being interconnectable contiguously and in parallel one with the other on moving said beam downwardly whereby the studs of each plate enter the slots of the other plate.
Claim 18
Dependent Claim
40 words
A device as claimed in claim 14 in which each plate has a pair of said slots in parallel one with another and a pair of said studs, the closed ends of the slots and the studs forming a rectangle.
