Dan 4w L P/c'A TEQ United States Patent 3,194,360 STRUCTURE Donald L. Richter, Mount Prospect, 111., assignor to Kaiser Aluminum & Chemical Corporation, Uakland, Calif., a corporation of Delaware Filed Mar. 16, 1962, Ser. No. 180,169 7 (Ilaims. ((31. 1892) This invention relates to ground anchoring arrangements for building structures. More particularly, this invention relates to improved ground anchoring arrangements for geodesic building structures of the type disclosed in my previously filed application, Serial No. 676,223 which matured as Patent No. 3,026,651 on March 27, 1962, filed August 5, 1957.

Accordingly, it is a primary purpose of the instant invention to provide a ground anchoring arrangement for a building structure of the type shown in the aforesaid patent application wherein improved means are utilized to secure the building structure to the ground.

Other purposes and advantages of the instant invention will become more apparent from a review of the following detailed description when taken in conjunction with the appended drawings, wherein:

FIG. 1 is a schematic view of a geodesic dome structure, the base perimeter of which can be anchored to the ground by the anchoring means of the instant invention;

FIG. 2 is a fragmentary perspective view of a portion of the base perimeter of the building structure shown in FIG. 1 and discloses in more detail the unique arrangement for anchoring the building structure to the ground;

FIG. 3 is a view with parts added and generally taken along line 3--3 of FIG. 2; and

FIG. 4 is an exploded view of the flanged column elements, etc., making up the ground anchoring arrangement of the instant invention.

With further reference to the drawings and in particular FIG. 2, the base perimeter anchoring means of the instant invention can be advantageously employed with the type of geodesic structure generally disclosed in my previously filed patent application Serial No. 676,223, filed August 5, 1957, wherein specially formed panels are employed. Since the structure of these panels and the manner in which they are secured together is fully disclosed in my previous application, no detailed discussion of the same is believed to be required.

The geodesic building structure, as indicated in FIG. 1 is generally made up of a plurality of panel members or structural units 2. These panels are four-cornered and are ,so formed that they are preferably diamondshaped in plan and have a major axis MM and a minor axis NN. The structural unit or panel includes corners or vertices 3, 4, 5 and 6, the corners or vertices 3 and 4 lying along the major axis and corners 5 and 6 lying along the minor. axis. Corners 5 and 6 are also displaced upwardly from the normal plane of rest of the sheet and, in turn, are connected by suitably shaped strut members 7 which lie along and generally coincide with the minor axis NN. The strut 7 is secured to a panel 2 by means of an apertured sleeve member which fits over the end of the strut or the ends of the strut can be provided with apertured flanged portions 8. Bolts or rivets (not shown) pass through suitable openings in the flanged portions 8 and corresponding openings in the panel adjacent the corners 5 and 6. Y

The sheet or panel 2 can also be advantageously provided with a plurality of delineations or creases 12 and 13, emanating from the major axial points or vertices 4 and 3 of the sheet.

The marginal edges of a structural unit or panel 2 are provided with reinforcing marginal flanges 9 which act as integrally formed frame elements for a building structure in which the panels 2 are incorporated.

As indicated in my previous application, the formed panel along with its strut 7 defines a tetrahedron-like solid or building block wherein certain integral portions of the panel serve as a framework While other integral portions of the panel serve as a covering for the building in which they are incorporated.

When one structural unit 2 is joined to another structural unit or panel 2 to form a series of building blocks, each panel, in effect, serves as a three-dimensional beam unit in a three-dimensional space truss structure. The mathematical arrangement of these structural units is such that load stresses are distributed substantially through all of the material in each unit and are directed to the diamond vertices or tips 3, 4, 5 and 6. These tetrahedron-like elements are of considerable three-dimensional strength and the central portion of a panel 2 located along the line or plane MM, i.e., a long diagonal, also advantageously acts in the manner of a strut or frame member.

When a plurality of the units 2 including a strut 7, are joined at a common point X, six of the units having adjacent flanged edges are located in abutting relation while the struts 7 of each of the six units are joined together and approximately define a regular hexagon, all as described more fully in my previous application.

To the aforesaid basic pattern there may be added additional series of structural units so arranged that the struts 7 are connected to the various vertex points B which comprise the conveying points of the short diagonals of the various four-sided and four-cornered panels. I

By securing the panels together in this fashion along with the struts 7 and the short diagonals thereof, the struts on adjacent units are also interconnected with each other, whereby the struts advantageously transfer loads from one to the other. By use of the structural panels herein described, the unique structure, as formed, has a geometrically patterned spider-like framework comprised of struts 7 and a surface wall of undulating marginally joined four-sided sheets. The geometric pattern or frame is generally a series of re-occurring hexagons. The total arrangement of the panels becomes that of a hexagonal strut overlying a three-dimensional covering of bowed panels 2. The structure formed from these panels 2 is also geodesic in that the vertices of all tetrahedronlike building blocks or structural elements 2 fall in a series of great circles which generally define a sphere in the case of the building structure shown in FIG. 1. In the building structure as shown in FIG. 1 each strut 7, the long and short diagonals and the marginal flanges 9 of any two contiguous units are positioned along great circle arcs.

The novel arrangement for anchoring a structure as shown in FIG. 1 to the ground will now be described. As illustrated, particularly in FIGS. 2-4, this arrangement contemplates that the bottom extremities of a plurality of panels located adjacent the bottom perimerical portions of the building structure will be directly anchored to a series of base supports or ground piers 14.

7 Base perimeter portions of the building are connected 7 etc. (not shown).

to piers 14 through the useof unique flanged columns 16. r Each of the flanged columns is generally comprised of i a webor base 17 and sideslfi. Each of the sides 18 is further provided with outwardly and somewhat downwardly disposed flange members 19. The sides lil pro-- ject in a converging fashionwith web 17 from one end 20 of the flanged column until they merge with the web 17 and flanges 19 adjacent the other extremity 21v of the flanged column. Thus, the other extremity 21 of the columnis somewhat triangular in cross-section.
