Geodesic dome

Abstract

A geodesic dome construction system utilizing a plurality of prefabricated flanged triangular panels and interior rigid insulation material. The flanged triangular panels are formed from single sheets of rigid material and fastened together on a flange-to-flange basis with sealant between the flanges. Along the interior face of the panel, rigid insulative material is attached with adhesive. The seams or voids along the edges of the rigid insulative material can be filled with foam insulation or other sealer which will further seal the interior flange seam of the flanged triangular panels. In addition, the interior face of the insulative material is covered with a coating to provide an interior finish and protection against damage.

I claim:  
     
         1 . A geodesic dome consisting of a plurality of flanged triangular panels whereby each panel is formed from a single sheet of rigid material.  
     
     
         2 . The dome of  claim 1  wherein said panel has flanges which are formed at acute angles in relation to the interior face of said panel.  
     
     
         3 . The dome of  claim 2  wherein said panels are fastened to one another at said flanges with the flanges facing the interior of said dome.  
     
     
         4 . The dome of  claim 3  wherein holes are provided in said flanges to accept fasteners.  
     
     
         5 . The dome of  claim 1 , further including rigid insulative material which is attached to the interior face of said flanged triangular panels.  
     
     
         6 . The dome of  claim 5  wherein seams between rigid insulative material are filled with insulative foam or equivalent sealer.  
     
     
         7 . The dome of  claim 5  wherein said rigid insulative material is coated with an interior finish.
