Abstract
Abstract A common joint assembly for a plurality of converging bracing members in an open support structure, such as an offshore drilling platform, including a polyhedral-shaped core and transition pieces for connecting each bracing member to a polygonal face of the core. Each transition piece has a larger cross section at the core than at the bracing member and has at least in part plane sides.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
204 words
A common joint structure for joining the converging ends of a plurality of braciNg members comprising: a. a polyhedral-shaped core having at least as many faces as there are bracing members leading to the joint, b. a plurality of transition members connecting each bracing member to a polygonal face of the core, each transition member being in line with the bracing member to which it is connected, the transition members each having at the end thereof connected to the bracing member a cross-sectional area equal to that of the adjacent part of the bracing member and smaller than the cross-sectional area of the transition member at the other end thereof where it is connected to the core and where this cross-sectional area is polygonal and at least in one direction equal in linear dimension to the linear dimension in the same direction of that face of the core to which the transition member is connected, each transition member having a number of plane faces at least equal to the number of sides of said polygonal cross section of the transition member at the end connected to the core, each side of said polygonal cross section being the edge of one of said plane faces.
Claim 2
Dependent Claim
204 words
A common joint structure for joining the converging ends of a plurality of braciNg members comprising: a. a polyhedral-shaped core having at least as many faces as there are bracing members leading to the joint, b. a plurality of transition members connecting each bracing member to a polygonal face of the core, each transition member being in line with the bracing member to which it is connected, the transition members each having at the end thereof connected to the bracing member a cross-sectional area equal to that of the adjacent part of the bracing member and smaller than the cross-sectional area of the transition member at the other end thereof where it is connected to the core and where this cross-sectional area is polygonal and at least in one direction equal in linear dimension to the linear dimension in the same direction of that face of the core to which the transition member is connected, each transition member having a number of plane faces at least equal to the number of sides of said polygonal cross section of the transition member at the end connected to the core, each side of said polygonal cross section being the edge of one of said plane faces.
Claim 3
Dependent Claim
34 words
A common joint structure as set forth in claim 1, wherein: a. the bracing members have circular cross sections, and b. the plane faces of the transition members are each alternated by part-conical faces.
Claim 4
Dependent Claim
40 words
A common joint structure as set forth in claim 1, wherein the core is formed by a plurality of flat plates and is provided in its interior with a plurality of stiffening plates to add greater rigidity to the core.
Claim 5
Dependent Claim
42 words
A common joint structure as set forth in claim 1, wherein the core has a vertical part of polygonal cross section from which transition members extend in an upwardly inclined direction, in a horizontal direction and one in a vertically upward direction.
Claim 6
Dependent Claim
50 words
A common joint structure as set forth in claim 4, wherein parts of polygonal cross section of the core extend in an upwardly inclined direction from the walls of the said vertical part of the core and are connected at their outer ends to the said upwardly inclined transition members.
Claim 7
Dependent Claim
51 words
A common joint structure as set forth in claim 4, wherein: a. the vertical part of the core has the shape of a vertical prism with a pentagonal cross section, and b. there are five pairs of horizontal and inclined bracing members lying in vertical planes and converging at the joint.
Claim 8
Dependent Claim
16 words
A common joint structure as set forth in claim 1, wherein the bracing members are hollow.
