       BRIEF SUMMARY OF THE INVENTION 
       [0009]    The apparatus described herein provides a unique design for a geodesic dome utilizing materials that are affordable and readily available throughout much of the world for the construction and connection of hubs and struts. 
         [0010]    In the preferred embodiment, hubs are formed from rebar and constructed by placing precisely cut rebar sections in specially designed jigs and welding the rebar sections together. The prongs of the rebar hubs are inserted into cement/concrete filled notched struts and wired into place. Once the cement/concrete hardens, the hub and strut connections provide compressive and tensile strength to the combination. Each hub and strut combination is then enclosed within a uniquely designed form that is filled with cement/concrete. The form is removed after the cement/concrete hardens thereby providing additional strength to the structure. The uniqueness of this design is the connection of the rebar hubs with struts using affordable and available materials. 
         [0011]    It is the intention that the invention described herein be used in regions that have suffered a natural disaster and are in need of humanitarian aid. The apparatus may be built or repaired with materials that are salvageable from destroyed structures or found in nature.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0039]    The embodiments discussed herein are merely illustrative of specific manners in which to make and use the invention and are not to be interpreted as limiting the scope of the instant invention. Referring to the above listed drawings in detail: 
       Hubs. 
       [0040]    The preferred embodiment of the apparatus and the method for making same utilizes 37 hexagon hubs ( FIG. 2 ), 6 pentagon hubs ( FIG. 1 ), 13 half-hexagon hubs ( FIGS. 3 ), and 6 entry hubs. The 6 entry hubs include 2 entry midway Ts ( FIG. 4 ), 2 entry tops ( FIG. 5  &  FIG. 6 ), and 2 entry bottoms ( FIG. 7  &  FIG. 8 ). The hubs are produced with cylindrical and notched jigs ( FIG. 19  &  FIG. 20 ). 
         [0041]    The jigs ( FIG. 19  &  FIG. 20 ) used to fashion the hubs are cylinders 2 inches high by 3.125 inches in diameter with 5 (for pentagon hubs) or 6 (for hexagon hubs) 0.5 inch by 0.5 inch notches ( 1901  &  2001 ) fashioned at equidistant intervals around the cylinder edge. (Notches are cut at 72 degree intervals for pentagon hubs and 60 degree intervals for hexagon hubs.) Placing the jigs on a flat surface with notched ends up will provide the proper inclination to achieve a 10 degree pronation of 8 inch long #4 rebar inserts with ends touching at the center to form a hub. Placing the 8 inch long #4 rebar inserts in the notched locations around the top of the jig with ends touching will set the inserts at the proper angles for strut orientation. 
         [0042]    The 37 hexagon hubs ( FIG. 2 ) are created by placing 6-8 inch long #4 rebar inserts ( 201 ) into a jig for hexagon hubs, described above, and welding the ends of the rebar inserts together in the center of the jig. 6-2 inch locking bars ( 202 ) are welded between the rebar inserts near the center of the hub. 
         [0043]    The 6 pentagon hubs ( FIG. 1 ) are created by placing 5-8 inch long #4 rebar inserts ( 101 ) into a jig for pentagon hubs, described above, and welding the ends of the rebar inserts together in the center of the jig. 5-3 inch locking bars ( 102 ) are welded between the rebar inserts near the center of the hub. 
         [0044]    The 13 half-hexagons ( FIG. 3 ) are created by placing 4-8 inch long #4 rebar inserts ( 301 ) into 4 adjacent notches in a jig for hexagon hubs, described above, and welding the ends of the rebar inserts together in the center of the jig. 3-2 inch locking bars ( 302 ) are welded between the rebar inserts near the center of the hub. 
         [0045]    The 2 entry midway Ts ( FIG. 4 ) are created by welding an 8 inch long #4 rebar insert ( 402 ) at the center point of a 16 inch long section of #4 rebar ( 401 ) at a 90 degree angle. 
         [0046]    The 2 mirrored entry tops ( FIG. 5  &  FIG. 6 ) are created by placing 5-8 inch long #4 rebar inserts ( 501  &  601 ) into a jig for hexagon hubs, described above, and welding the ends of the rebar inserts together in the center of the jig. 4-2 inch locking bars ( 502  &  602 ) are welded between the rebar inserts near the center of the hub. A 6 th  8 inch long #4 rebar insert ( 503  &  603 ) is welded into the hub creating a 90 degree angle in relation to the left adjacent insert and 30 degree angle in relation to the right adjacent insert. For the mirrored entry top, a 6 th  8 inch long #4 rebar insert is welded into the hub creating a 90 degree angle in relation to the right adjacent insert and 30 degree angle in relation to the left adjacent insert. 
         [0047]    The 2 mirrored entry bottoms ( FIG. 7  &  FIG. 8 ) are created by placing 2-8 inch long #4 rebar inserts ( 701  &  801 ) into 2 adjacent notches in a jig for hexagon hubs, described above, and welding the ends of the rebar inserts together in the center of the jig. 1-2 inch locking bar ( 702  &  802 ) is welded between the rebar inserts near the center of the hub. A 3 rd  8 inch long #4 rebar insert ( 703  &  803 ) is welded into the hub creating a 270 degree angle in relation to the left adjacent insert and 30 degree angle in relation to the right adjacent insert. For the mirrored entry bottom, a 3 rd  8 inch long #4 rebar insert is welded into the hub creating a 30 degree angle in relation to the right adjacent insert and 270 degree angle in relation to the left adjacent insert.

       [0177]    After the frame is assembled and the concrete in the struts has cured for three days, the forms and concrete are ready to be installed over the hub connections. 1) Place a pentagon or a hexagon form under the center of the corresponding metal hub. 2) Fold the flaps around the struts. 3) Take the string over the struts and wrap around the screw on each flap securing the form to the framework. 4) When the form is in the horizontal position, secure the flaps and fill concrete from the top. 5) When the form is in the vertical position, leave the top flap untied for inserting concrete. 6) For vertical forms, place the outer part of the form with the notched side facing outward against the ends of the flaps of the attached form. 7) Secure wire around the strut below the notch in the outer part of the form. 8) Pull the wire across the notch in the form and secure the wire on an opposing strut below the end of the notch. 9) Repeat Step 8 by running the wires through the axes of the hub until all of the axes are secure. 10) Tighten the wires to bend the outer form into to the shape of an apex shape. 11) Draw the surface of the outer form to the ends of the flaps of the inner form. 12) Pour concrete mix in the upper opening of the form filling the form to the top. 13) Vibrate form to remove any voids in the pour to make a good cast. 14) After the concrete has set, snip the wires and remove the outer parts of the forms. 15) Untie the strings of the inner form, open up the flaps and remove the inner part of the form. Check for voids in the casting and repair as needed. 
       Coverings. 
       [0178]    Coverings may be utilized as shown in  FIG. 17 ,  FIG. 18 ,  FIG. 22 , and  FIG. 23 . An “AAB Panel” ( 1701 ) is formed of OSB panel, or any other suitable material, and cut to cover a triangular aperture created by two “A Struts” ( FIG. 9 ) and one “B Strut” ( FIG. 10 ). Bracing rods ( 1702 ) may be affixed to the “AAB Panel” via wire or string and bracing rod holes ( 1703 ). The “AAB Panel” may be affixed to the two “A Struts” and one “B Strut” via wire or string and “AAB Panel” holes ( 1704 ). A “CCB Panel” ( 1801 ) is formed of OSB panel, or any other suitable material, and cut to cover a triangular aperture created by two “C Struts” ( FIG. 11 ) and one “B Strut” ( FIG. 10 ). Bracing rods ( 1802 ) may be affixed to the “CCB Panel” via wire or string and bracing rod holes ( 1803 ). The “CCB Panel” may be affixed to the two “C Struts” and one “B Strut” via wire or string and “CCB Panel” holes ( 1804 ). 
       Panel Assembly. 
       [0179]    1 st  Step: Place the AAB panel on the struts that form a pentagon in the middle of the dome. Locate the AAB Struts that correspond to the sides of the panel. 
         [0180]    2 nd  Step: Place the AAB panel on the triangle formed by the A Struts and B Strut with the 1″ bamboo braces resting on the 2″ bamboo struts. 
         [0181]    3 rd  Step: Wrap the panel lashing wires (attached to the panel) around the Struts and twist until panel is drawn tight against the cement hubs and 1″ panel braces. 
         [0182]    4 th  Step: Lock the next AAB panel into the mounted AAB panel by placing the A side over hanging 1″ bamboo braces under the existing panel's A side and sliding the edges together. Line up the points of the angle's A side. Lash the panel into place drawing the panel tight against the struts and hubs. 
         [0183]    5 th  Step: Continue locking and securing AAB panels into place until the last triangle in the Pentagon is to be put in place. 
         [0184]    6 th  Step: Lock the next AAB panel into the mounted AAB panel by placing the A side over hanging 1″ bamboo braces under the existing panel's A side and sliding the edges together. Line up the points of the angle's A side. Use a mallet to help drive the 1″ bamboo braces back and forth until the panel is locked into place on both sides of the panel. Lash the panel into place drawing the panel tight against the struts and hubs. 
         [0185]    7 th  Step: Place a CCB panel up against an AAB panel with the B sides lined up with each other. Place the CCB panel on the triangle formed by the C Struts and B Strut with the 1″ bamboo braces resting on the 2″ bamboo struts. Lock the CCB panel into the mounted AAB panel by placing the B side over hanging 1″ bamboo braces under the existing panel's B side and sliding the edges together. Line up the points of the angle's B side. Push the panel into place drawing the panel tight against the struts and hubs with the lashing wires. 
         [0186]    8 th  Step: Lock the next CCB panel into the mounted CCB panel by placing the C side over hanging 1″ bamboo braces under the existing panel's C side and sliding the edges together. Line up the points of the angle's C side. Use a mallet to help drive the 1″ bamboo braces back and forth until the panel is locked into place on both sides of the panel. Lash the panel into place drawing the panel tight against the struts and hubs. 
         [0187]    9 th  Step: Continue locking the panels together, lining up A to A sides, B to B sides and C to C sides until the dome is covered.
