Description
- Geodesic domes are generally formed of multiple triangular plate like patterns arranged together, and such constructions are well known in the art. These dome shaped structures are assembled by combining triangle shaped patterns to an adjacent pattern to define a cohesive structure. A geodesic dome includes a formation of repetitive triangular patterns, which define the surface of the dome. The construction of the dome structure is characteristically defined by a sequence of struts which are linked to common hubs to generate the dome's framework. The surface area generated amongst one of the three adjoining struts or the triangles must essentially be portioned, bounded, and secured, as they are of a substantial dimension which is inter-reliant with the overall diameter of the geodesic dome.
- In the conventional systems or prior arts, the geodesic domes are constructed in multiple ways, such as, one system discusses geometric tile members which are secured together to define a three-dimensional geometric shape, which are combined with other such geometrically shaped tiles of such three dimensional characteristics to form the dome. Another method comprises carefully arranging polygonal panels in such a way so that they slide into lateral pouches formed on each side of a strut. Some other conventional panels for geodesic domes are constructed in the form of sheet members, with inner and outer faces of the sheet member being connected to an intermediary backing member.
- Most conventional geodesic domes are constructed by a method that includes multiple steps, and includes an intricate structure to connect neighboring tiles to the struts that back them up. However, in most of the above mentioned constructions, there are several major problems that exist, such as, instability of the framework of the dome structure owing to poor method of connecting and fastening of dome hubs, and none of the methods are focused on allowing a dimensional lumber, for example, a wooden framing member, to be in inserted and fastened into the completed or assembled geodesic dome frame.
- Hence, there is a long felt but unresolved need for a strut which can strengthen the hub of the geodesic dome structure, as well as provide provisions to insert and fasten dimensional lumber sections into the geodesic dome structure.
- The strut disclosed herein addresses the above mentioned need for a device which can strengthen the hub of the geodesic dome structure, as well as provide provisions to insert and fasten dimensional lumber sections into the dome structure. The strut disclosed herein, where multiple such struts are configured to form a geodesic dome, where each strut comprises multiple elongate rod members with multiple fastener-through holes defined on each of the elongate rod members. The opposing ends of each elongate rod member comprises a bolt hole configured to receive a fastener member, where each of the opposing ends of one elongate rod member is joined and fastened to other opposing ends of the other elongate rod members to define a hub, thereby defining a framework for the geodesic dome. Each fastener-through hole is configured to fasten a covering material of a predefined configuration over the framework defined by the elongate rod members, thereby forming the geodesic dome.
- In an embodiment, the elongate rod members are flanged elongate sections made of sheet metal. In an embodiment, the thickness of the sheet metal forming the elongate rod member is variable. In an embodiment, the strut further comprises a formed stiffening ridge defined proximal to the opposing ends of each of the elongate rod members, where the formed stiffening ridge is configured to provide additional strength to the hubs formed by the elongate rod members. In an embodiment, the hub defined by the elongate rod members is fastened via the fastener members which are inserted through each bolt hole positioned on one of the opposing ends of the adjacent elongate rod members connected together, for example, a bolt and nut of any type, but not limited to a machine screw and a wing nut. In an embodiment, the fastener-through holes for fastening the covering material are configured to define a reference template for the manufacturing of similar material pieces which need to be fastened over the struts. In an embodiment, the flanged elongate section which defines the elongate rod member further defines a channel configured to receive and attach a lumber section to provide additional strength to the geodesic dome and accept fasteners which hold covering material in place.

As shown inFIG. 2 , theopposing ends elongate rod member 101 comprise abolt hole 107, where each of theopposing ends elongate rod member 101 is joined and fastened to otheropposing ends elongate rod members 101 to define ahub 102, thereby defining aframework 103 for the geodesic dome. Each fastener-throughhole 104 is configured to fasten a coveringmaterial 300 of a predefined configuration over theframework 103 defined by theelongate rod members 101, thereby forming the geodesic dome. In an embodiment, thehub 102 defined by theelongate rod members 101 is fastened viafastener members bolt hole 107 positioned on one of theopposing ends elongate rod members 101 connected together, for example, thefastener members machine screw 105 as shown inFIG. 1A , and awing nut 106 as shown inFIG. 1B . -
FIG. 2 exemplarily illustrates a top perspective view of anelongate rod member 101. In an embodiment, theelongate rod member 101, as further shown in the FIG.2 byreference numerals elongate rod member 101 is variable. The sheet metal section is flanged or folded into a generally rectangular cross section as shown inFIG. 2 . In an embodiment, thestrut 100 further comprises a formedstiffening ridge 108 defined proximal to theopposing ends elongate rod members 101, where the formedstiffening ridge 108 is configured to provide additional strength to thehubs 102 formed by theelongate rod members 101.

FIG. 3 exemplarily illustrates a top perspective view of a coveringmaterial 300 being positioned over thestrut assembly 100. In an embodiment, the fastener-throughholes 104 for fastening the coveringmaterial 300 are configured to define a reference template for the manufacturing of similar coveringmaterial 300 which need to be fastened over thestrut assemblies 100. The precisely positioned fastener-throughholes 104 for fastening the coveringmaterial 300 allow for the use of a template when creating the triangular panels, and this aspect is not used in the conventional construction of geodesic domes. There are different patterns of fastener-throughholes 104, for example, randomly oriented fastener-throughholes 104 a, or closely positioned fastener-through holes 104 b as shown inFIG. 3 . The fastener-through holes 104 b allow a user to identify the various different struts for assembly. The spacing of the fastener-throughholes 104 that are positioned along the surface of theelongate rod members 101 allows for the fasteners to be inserted from the outer covering material, for example, plywood, into thedimensional lumber section 301 which occurs in thechannel 109, and therefore can be easily manipulated to incorporateother covering materials 300 to be installed adjacently. Thechannel 109 provides the space for thedimensional lumber 301 to be snuggly seated and fastened within thechannel 109 to provide added strength to thestrut 100 as further exemplarily illustrated inFIG. 4 . - The
multiple struts 100 from which the geodesic dome can be constructed allow for the use of commonly available dimensional lumber and covering materials to be installed once themetallic framework 103 is assembled. Such a procedure allows a technically difficult project to be completed using commonly available material with low level expertise, where a user can obtain readily available material from a lumber yard and cut and install the lumber and covering material. This also allows for the creation of various wall thickness of the finished structure, for example use of 2×4, 2×6, or 2×8, members. In an example, plywood and other covering materials can then be fastened into the wood through the fastener-throughholes 104 existing on each of theelongate rod members 101 defining thestrut assembly 100, thereby creating a livable structure, for example, a dwelling or greenhouse. -
FIG. 4 exemplarily illustrates a side perspective view of a portion of the coveringmaterial 300 being positioned over thestrut assembly 100, as shown inFIG. 3 . In an example,strut assembly 100, as disclosed here, creates the metallic structure which is assembled of struts orelongate rod members 101 making a finished dome shape with its own strength. Theelongate rod members 101 havechannels 109 which face inwards in the geodesic dome which is defined by theelongate rod members 101. Thelumber section 301, such as, 2×4 pieces, are inserted on the inside of the structure in thestrut channels 109 where thelumber sections 301 are configured to snuggly fit. In an example, a coveringmaterial 300 such as plywood, is installed on the outside of the dome over thestrut assembly 100 and the fasteners such as screws go through the plywood, through the fastener-throughholes 104 in theelongate rod members 101 and fasten into thelumber sections 301, such as 2×4 pieces, which are in thechannel 109 of thelumber sections 301. - The foregoing examples have been provided merely for the purpose of explanation and are in no way to be construed as limiting of the present concept disclosed herein.
