Abstract

PURPOSE: To obtain a diving spherical body easy to manufacture with large strength against pressure, by building up many T-shaped steel pieces to frame-shape in such a manner that their flange part faces outward further their web inward, welding the pieces and forming a spherical shell.
CONSTITUTION: Flanges 2A of many T-shaped steel pieces 2 are faced outward and webs 2B of them are faced inward to build up respectively to frame shape, perform welding to one another and form a spherical shell 3. The T-shaped steel pieces 2 are arranged in such a manner that their web 2B is situated within a plane including the center O of a spherical body to form an enclosure S, and the enclosure S is enclosed by welding a metal plate 4 overhung inward of the spherical shell 3. The metal plate 4 is previously formed to such curved shape as durable with expansion force for pressure exceeding water pressure applied in the depths of the sea.
