    • PURPOSE:To ensure the proper ascent and descent of a roof by rotating a shaft on the operation of a drive mechanism for the subsequent rotation of a screw shaft and vertical motion of a nut member along the screw shaft on the rotation thereof to cause a roof support section for bearing the roof to ascend and descend. CONSTITUTION:A roof structure body 21 is provided at a position above a baseball field 71, so as to be capable of freely ascending and descending. The body 21 has a trapezoidal form and a soccer field 77 using natural turf is formed on the upper surface of the body 21. In a dome structure, the body 21 is elevated up to the uppermost position of roof support pillars 23 and ceiling height is made maximum, when a baseball game is watched. On the other hand, when a soccer game is watched, using the soccer field 77, the body 21 is lowered to the lowermost position of the pillars 23. In a roof elevating device so constituted, therefore, when a shaft 45 is rotated with a motor 57 via a reduction gear 59, a screw shaft 27 is rotated and a nut member 29 vertically moves along the screw shaft 27 due to the rotation thereof. Thus, a roof support section to bear a roof is made to ascend and descend. According to this construction, the roof can be made to properly ascend and descend via the application of a simple construction.

    • PROBLEM TO BE SOLVED: To provide a roof frame connection device which reduces stress burden on an open and close type roof of facility such as an outdoor theater having no enclosure wall in its surrounding. SOLUTION: An open and close roof 14 is constituted in such a manner that a plurality of arch element 13 in which a membrane material is stretched on a truss frame body, a wheel is mounted on an end side of a lower end part, of which is decreased gradually when approaching the inside of a structure, and of which plan is like a wedge are constituted, and side end part of a central part of the structure in each arch element 13 are superposed on each other and supported like a pivotal point of a fan in such a manner that they can rotate freely on a support structure 16 in the structure, respectively, and are put on horizontal guide members 18 like circular arc which are laid at many steps in an open part of an end side face provided in a support frame 17 on the opposite side through the wheel in such a manner that they can run freely so that the arch elements 13 are piled up at many steps in such a manner that load can be transmitted when the roof 14 is opened. In this case, a connection and integration device 19 is arranged between upper and lower arch elements which oppose mutually on a peripheral locus close to the center of a span of the multi-step arch elements 13 to connect and integrate the upper and lower arch elements 13 when the roof is in a condition in which the roof is at many steps and is open.
