Abstract
Abstract A building structure with a plurality of strut members forming a geometric configuration having a plurality of vertices. A joint member joins the strut members at each of the vertices and a plurality of panel members bridge the strut members. Each of the panels is connected at its edge to a strut member under springlike action providing frictional engagement with the strut member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
151 words
A space enclosing building structure comprising: a. a plurality of strut members joined at a plurality of vertices forming a plurality of geometric configurations giving a space grid structural frame; b. means at each vertex joining the strut members at each vertex and for making distance between the vertices adjustable which includes: 1. a polyhedral member having a plurality of holes; 2. a threaded stud corresponding to each strut member inserted into one of the holes in the polyhedral member; 3. a threaded plug engaging each threaded stud, an opposite end of the threaded plug threaded into an end of the strut member; and c. a plurality of panel members bridging the strut members and stressed by the frame, each panel having an edge which is semipolygonal in cross section which engages the strut, the semipolygonal crOss section having an extension which joins a corresponding extension from an adjacent panel edge.
