A dome constructing method comprising the steps of assembling a triangular frame, which is the fundamental unit for a polyhedral skeleton, by using three joints and three frame members with the three joints used as the apexes and the three frame members used as the sides and with the triangular frame in contact with the ground, assembling new triangular frames around the ground-contacting triangular frame by using similar frame members and joints, thereby assembling the polyhedral skeleton of a multipyramid, such as pentagonal pyramid or hexagonal pyramid, with one joint that is positioned at one apex in the ground-contacting triangular frame being used as the apex and with the ground-contacting triangular frame used as one surface, wherein each time the polyhedral skeleton for the multipyramid is thus assembled, the same is turned to bring a new triangular frame other than the ground-contacting triangular frame into contact with the ground and then the assembling operation is repeated to assemble a polyhedral skeleton, thus constructing a spherical dome.

A construction element according to claim 3, wherein the element has two substantially cylindrical curved faces and the longitudinal flat bars of each armouring section are curved so that their external faces are parallel, respectively to the corresponding facings of the element. 5. A construction element according to claim 1, wherein the transverse linking armouring between two respectively active and passive longitudinal flat bars comprise a series of distinct elements each composed of a band with two bent ends respectively on the internal faces of both longitudinal flat bars. 6. A construction element according to claim 1, wherein the element has two substantially cylindrical curved faces and the longitudinal flat bars of each armouring section are curved so that their external faces are parallel, respectively to the corresponding facings of the element.
