Garden Dome 3


The three subdivisions of Garden Dome 3 - Top Views

GD3-X1 This first illustration depicts all the triangles of the dome bisected or cut in half by the addition of a strut. By using the Multi-Max hub system 75 struts are added to the dome for extra structural stability for larger domes. Recommended for domes 30 - 40+ feet in diameter where more structural strength is required, for example when adding roof panels or areas with greater snow loads. Note that no extra hubs are added to this version of Garden Dome 3. There are 2 basic sizes of struts added and attached from the hubs to the original dome struts by means of 4-way connecting plates or other convenient methods.

GD3-X2 Each original triangle of the dome is subdivided into three triangles for a total of 225 additional struts. Our special connecting system makes this a logical, natural and practical method for giving superior triangulated strength to the spherical shape. The pentavalent and hexavalent hubs become vertices for joining 10 and 12 struts at a hub. 75 hubs are also added for connecting the added struts. Recommended for domes 30 - 45 feet in diameter or larger for added structural integrity.View pictorial illustration


 
 
 

GD3-X3 Each triangle of the original Garden Dome 3 is subdivided into 6 triangles. In other words 225 struts are added to the GD3-X2 (or, 450 struts and 75 hubs to the original GD3). View pictorial illustration


 
 
 
 
 
 
 
 
 

Note: The original triangle faces of the dome are left intact. In other words the subdivision struts do not break the triangle face plane of the original Garden Dome 3.

You may have noticed how varieties of the three Garden Dome 3 versions may be used in one dome frame to facilitate installation of windows, door entries etc. There is flexibility in the design variables- combinations of subdivisions types, materials, etc. to suit a particular purpose and appearance.

These color enhanced illustrations are representative only to present a concept of the basic design and proportions. The subdivided Garden Dome 3 is shown without the Base Option added. Here are some paper model plans of -X2 and -X3 shown above.X - FILES
