摘要： PURPOSE:To enable a building to have a degree of freedom in area and form by dividing a roof into a plurality of elements for connection with hinges, supporting the grouped top of each roof element in such a way as to be capable of free vertical motion, and providing a movable recessed wall at a wall section. CONSTITUTION:A roof is constituted with a plurality of roof elements 1 radially divided, and the elements 1 are jointed with hinges 2. Also, the grouped top 4 of each element 1 is supported with a screw jack 5, and a movable nut 6 screwed into the screw jack 5 and a rotary core member 7 pivotally supported on the grouped top 4 are connected to each other with a lever 8. In this case, when the screw jack 5 is driven to rotate with a motor 9, the nut 6 moves vertically, and the rotary core member 7 opens or closes about the grouped top 4. Furthermore, the roof element l connected to the rotary core member 7 rotates thereabout, and the shape of the roof changes. Also, mean peripheral length formed with the external surface of each element 1 changes. As a result, recessed walls 14 and the corner columns 10 thereof move respectively along rails 16 and 15. According to the aforesaid construction, a building area increases or decreases as well, according to a change in the peripheral length of the roof. Also, the roof and wall can be fixed at a desired position.

摘要： PURPOSE:To achieve efficient and economical construction of prefabricated big space roof structure for such buildings as a gymnasium, a public hall, etc. by connecting curved central materials in a desired curvature with straightened materials in the tangential direction and by making them into corrugated frameworks by bonding the adjoining materials each other. CONSTITUTION:At the opposite ends of a curved central material 1, straightened end materials 2 are fixed, extending in the tangential directions, and an unit A is made thereby. The units A are continuously placed either in the span direction or in the latitudinal direction passing through the zenith of spherical surface. The outermost parts of the corrugations of the adjoining units A, i.e. the center of the curved central materials 1, are continuously superimposed and bonded each other with bonding metal 6 either in the ridge direction or in the longitudinal direction. By continuously arranging the corrugated frame work materials in the two directions intersecting each other, a big space frame is constructed. Therefore depending on selection out of a variety of radius of curvatures, construction can be made in various shapes. As the construction is made from the unit materials A, less-expensive prefabricated structure can be achieved.
