Title:
【発明の名称】球殻構造体形成用構造ユニット及び該構造ユニットを用いた球殻構造体並びにその収納及び組立方法
Document Type and Number:
Japanese Patent JP3370960
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a spherical shell structure body formed to obtain suitable structural strength, a lightweight structural unit for forming the spherical shell structure body, and an efficient assembling method for the spherical shell structure body. SOLUTION: This frame structural unit 10 is constituted to have an outermost edge frame formed in regular hexagonal shape, provided with side connecting mechanisms 13 with three non-adjacent side members of six side members 11 as connected sides, or a skeleton structural unit 20 is constituted to have regular hexagonal shape formed by connecting the apexes of radial skeleton members 21, comprising point connecting mechanisms 23 with the respective apexes of the skeleton members 21 as connected points, the adjacent connected points of which are paired. Twenty frame structural units 10 or skeleton structural units 20 are used and fixedly connected through all the side connecting mechanisms or point connecting mechanisms of the respective units so that an interior angle defined by the planes of the respective connected units is 138.2 deg., thus constituting this spherical shell structure body with twelve regular pentagonal cavities.
