ABSTRACT:
A method of and apparatus for making a self-supporting dome-like skeletal structure including the steps of preparing a substantially flat surface, assembling an array of multi-sided first members which is criss-crossed by paths comprising adjacent flanges of adjacent first members, placing a strip of pliable material along each path and interweaving the strips at intersections thereof, securing the ends of the strips, mounting over each first member a second member of configuration similar to said first member, said second members peripherally sealingly resting on the strips on the flanges of the first members, placing concrete in troughs having as sides the sides of adjacent second members and as bottoms the strips on the flanges of the first members and introducing pressurized gas below said array of first members to cause it to assume a dome-like configuration, allowing the concrete in the troughs to set and exhausting the gas from below the first members so as to strip at least said first members from the concrete skeleton so formed.
