Arrangement for connecting structural members

Claim 2

An arrangement for connecting structural members, particularly members of a frame or scaffold, comprising a first elongated member having two end portions, at least one of said end portions being provided with an elongated recess having one open end and a first throughgoing passage extending substantially transversely to the elongation of said recess; a second elongated member to be connected with said first elongated member; a third member fixedly mounted on said second member and extending outwardly away from the second member, said third member being adapted to be received in said recess when said first and second members are connected to each other, said third member being provided with at least one second throughgoing passage so arranged on said third member as to communicate and bound with said first passage an uninterrupted channel; a fourth member closely receivable in said channel so as to arrest said second member on said first member to thereby prevent any movement of said first and second members relative to one another; and a fifth member fixedly spaced from said first member and having first and second portions, an intermediate portion spaced from said first member and extending substantially parallel thereto, said first and second end portions being bent relative to said intermediate portion in direction towards said first member and being rigidly connected thereto.

Claim 3

An arrangement as defined in claim 1, wherein said second member extends substantially vertical when the latter is connected to said first member.

Claim 4

An arrangement as defined in claim 2, wherein said third member is a disc having a central throughgoing hole operative for closely receiving therein said second vertical member.

Claim 5

An arrangement as defined in claim 3, wherein said recess has a predetermined width measured in direction transversely to that of the extension of said recess and slightly exceeding that of said disc.

Claim 6

An arrangement as defined in claim 4, wherein said fourth member is a wedge.

Claim 7

An arrangement as defined in claim 5, wherein said second throughgoing passage has a cross-section adapted to closely receive said wedge therein upon displacing said wedge through said second passage.

Claim 8

An arrangement as defined in claim 6, and further comprising a fifth member fixedly spaced from said first member and extending substantially parallel thereto.

Claim 9

An arrangement as defined in claim 1, said first elongated member is provided with an element fixedly mounted on said first member, said element being provided with said first passage and said recess.

Claim 10

An arrangement as defined in claim 1, wherein said disc is provided with a first plurality of said second passages uniformly spread one from another by a predetermined distance.

Claim 11

An arrangement as defined in claim 9, wherein said disc is further provided with a second plurality of third throughgoing passages uniformly spread on said disc so each said third passage is surrounded by two of said second passages.

Claim 12

An arrangement as defined in claim 10, wherein each of said third passages has a cross-section substantially exceeding that of said second passage.

Claim 13

An arrangement as defined in claim 7, wherein said fifth member has two end portions at least one of said end portions being fixedly connected to said second member.

Claim 14

An arrangement as defined in claim 12, and further comprising detachable means for connecting at least one of said end portions of said fifth member to said second member.

Claim 15

An arrangement as defined in claim 13, wherein said connecting means comprise an angular-coupling element fixedly connecting said fifth member to said second member.

Claim 16

An arrangement for connecting structural members, particularly frame girders, comprising a plurality of frame girders, each having a first substantially horizontally elongated member, a second elongated member having at least one substantially horizontal portion extending parallel to said first member and a plurality of connecting elements extending angularly between said first and second members and connecting the same so as to constitute together with said first and second members a frame girder, said first member having two end portions and at least one of said end portions being provided with an elongated recess having one open end and a first throughgoing passage extending substantially transversely to the elongation of said recess; a third elongated member to be connected with the frame girder; a fourth member fixedly mounted on said third member and extending outwardly away therefrom, said fourth member being adapted to be received in said recess of said first member when said third member is connected to the frame girder, said fourth member being provided with at least one second throughgoing passage so arranged on said fourth member as to communicate and bound with said first passage an uninterrupted channel; and a fifth member closely receivable in said channel so as to arrest said third member on the frame girder to thereby prevent any movement of the latter and said third member relative to each other.

Claim 17

An arrangement for connecting structural members, particularly frame girders, comprising a plurality of frame girders, each having a first substantially horizontally elongated member, a second elongated member having at least one substantially horizontal portion extending parallel to said first member and a plurality of connecting elements extending angularly between said first and second members and connecting the same so as to constitute together with said first and second members a frame girder, said first member having two end portions and at least one of said end portions being provided with an elongated recess having one open end and a first throughgoing passage extending substantially transversely to the elongation of said recess; a third elongated member to be connected with the frame girder; a fourth member fixedly mounted on said third member and extending outwardly away therefrom, said fourth member being adapted to be received in said recess of said first member when said third member is connected to the frame girder, said fourth member being provided with at least one second throughgoing passage so arranged on said fourth member as to communicate and bound with said first passage an uninterrupted channel; and a fifth member closely receivable in said channel so as to arrest said third member on the frame girder to thereby prevent any movement of the latter and said third member relative to each other.
