Abstract:
1. A monolithic dome building including a generally dome shaped unitary monolithic peripheral wall that includes a mesh reinforced built-up layer of cementitious material defining an outer generally convex surface and an interior chamber and having an access opening enabling entry into and exit from the chamber, and a rigid unitary door operatively associated with the building and adapted for lateral movement between a first position closing said access opening and a second position enabling passage through the access opening, said door having a rigid frame structure supporting an outer metallic sheet or a mesh reinforced built-up layer of cementitious material defining a generally unitary closure wall having a three-dimensional convex external contour substantially similar to the outer convex contour of the dome shaped building adjacent the access opening, said door being supported on the building at an upper margin of the door on a substantially horizontal guide track for lateral movement between said first and second positions, said guide track extending internally of said chamber adjacent a wall of the building so that the door complements the dome shaped peripheral wall when in its first position and is disposed in closely spaced relation to said wall when in its second position.
