Abstract
Abstract The method of assembling a framework, comprises assembling at least a portion of its rib members to one another, at their ends, by means of wedge shaped elements. A part of generally frustoconic shape is driven into the framework at the point of convergence of at least three rib members to render it rigid.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
60 words
Method of assembling a spherical framework including a plurality of rib members, comprising fastening at least a portion of its rib members to one another at their ends by means of wedge shaped elements, and driving a member of generally frustoconic shape into the framework at the point of convergence of at least three rib members to render it rigid.
Claim 2
Dependent Claim
60 words
Method of assembling a spherical framework including a plurality of rib members, comprising fastening at least a portion of its rib members to one another at their ends by means of wedge shaped elements, and driving a member of generally frustoconic shape into the framework at the point of convergence of at least three rib members to render it rigid.
Claim 3
Dependent Claim
44 words
Method according to claim 1, wherein a network of ribs forming the sides of triangles by means of rectilinear rib members and wedge shaped elements is assembled so that the angles of said triangles comprise the support points of the surface of a dome.
Claim 4
Dependent Claim
49 words
Method according to claim 1 wherein the ends of the rib members are assembled by wedge shaped elements having a base in which a notch is formed so as to provide two wings inbetween the two sides of the wedge, each of said wings having at least one perforation.
Claim 5
Dependent Claim
41 words
Method according to claim 1 wherein the ends of the rib members are assembled by wedge shaped elements made of two plates hinged together along one of their edges, and including means for adjusting the angle defined between such two plates.
Claim 6
Independent Claim
63 words
A method for assembling the framework of a structural surface with apexes comprising the steps of: forming a network of polygonal cells by fastening wedge shaped elements to rectilinear rib members at their ends, and raising the framework towards said apexes by driving a frustoconical member into the framework at the junction of rib members of the polygonal cells surrounding each said apex.
