A dome constructing method for constructing a spherical dome by assembling a polyhedral skeleton and then by finishing the interior/exterior of the same. A plurality of joints, which are to be arranged when assembled at the positions of the individual vertexes of a polyhedral skeleton and each of which has a plurality of joint blades in the directions of the individual sides of the polyhedral skeleton, as extended from said individual vertexes, and a plurality of frame members are adopted as members for constructing the polyhedral skeleton of the spherical dome. Three joints and three frame members are assembled into a triangular frame or a basic unit of the polyhedral skeleton in a grounded state by using the three joints as the vertexes and the three frame members as the individual sides of the triangular frame. Moreover, a new triangular frame is assembled around said grounded triangular frame by using similar frame members and joints, thereby to assemble the polyhedral skeleton of a polyhedral cone such as a pentahedral cone or a hexahedral cone, which uses the joints positioned at one vertex of said grounded triangular frame as its vertex and said grounded triangular frame as its one side. Each time the polyhedral skeleton of the polyhedral cone is thus assembled, a triangular frame different from said triangular frame is newly grounded by turning said polyhedral skeleton, and the polyhedral skeleton is subsequently assembled by repeating similar assembling works. Next, said polyhedral skeleton is finished on its interior/exterior to construct the spherical dome.

L'invention concerne un procédé de construction d'un dôme, ce procédé consistant tout d'abord à assembler, à l'aide de trois joints et de trois éléments de cadre, un cadre triangulaire composant l'unité fondamentale d'un squelette polyédrique. Les trois joints sont utilisés comme sommets alors que les trois éléments de cadre font office de cotés, ledit cadre triangulaire étant en contact avec le sol. Ce procédé consiste ensuite à assembler les nouveaux cadres triangulaires autour du cadre en contact avec le sol, au moyen d'éléments de cadre et de joints identiques, ce qui permet d'assembler le squelette polyédrique d'une pyramide à plusieurs cotés, par exemple une pyramide pentagonale ou une pyramide hexagonale, un joint placé au niveau d'un sommet du cadre triangulaire en contact avec le sol étant utilisé comme sommet, et ledit cadre triangulaire en contact avec le sol formant une surface. Chaque fois que le squelette polyédrique de la pyramide à plusieurs cotés est assemblé, un nouveau cadre triangulaire, autre que le cadre triangulaire en contact avec le sol, entre lui-même en contact avec le sol, cette opération d'assemblage étant ensuite répétée afin d'assembler un squelette polyédrique et ainsi de construire un dôme sphérique.
