2. Description of the Related Art Conventionally, roof structures used in buildings, stadiums, outdoor exposition halls, etc. are represented by conventional compression-bending roof structures such as shells and trusses, openable roof structures, membrane structures and cables. It is divided into the field of tension structures. Conventionally, the open / closed roof structure is such that the rigid roof structure is opened and closed by rigidly rotating or moving in parallel, as represented by the Music Hall in Pittsburgh in the United States, the Sky Dome in Toronto, Canada and the Fukuoka Dome. Many have been proposed and used in practice. This openable roof structure is a system in which a spherical dome is divided into steel roof panels, and the upper panel is opened and closed by turning the upper panel on a traveling path of a perfect circular orbit.

[0003] On the other hand, a tension structure is a structure in which a lightweight cable material or a film material is used as a roof structure by tensioning the cable structure. Among them, a typical example of the cable structure is the Olympic Stadium in Munich, Germany. As a structure, such as a tent structure, Izumo, Akita, Odate Dome, etc.
A tension film structure that introduces tension to the film surface and tensions it, and an air film structure that introduces air and expands the film surface to tension the film surface, such as Korakuen Tokyo Dome, have already been used.

Further, a double air film structure such as a Kumamoto dome is also used. Although a tension structure can realize a lightweight roof frame, a reaction force structure for introducing tension is required at the boundary around the roof. An open / close roof using a membrane surface has been proposed as a device that covers the above two fields. There have been proposed a type using a membrane material as a roofing material of an openable roof structure (Miyazaki Seagaia) and a type in which a membrane material is stretched on a foldable frame and the membrane surface is folded and stored together with the frame. In addition, there is a Canadian Montreal Olympic Stadium and the like as an openable roof utilizing the flexibility of the membrane material.

The conventional large roof structure without opening and closing resists severe external force conditions such as its own weight, wind load, snow load, etc., so that the whole roof integrally resists external force. In addition, the whole structure was closed and the structure was completed, for example, utilizing the mechanical continuity of a dome-like structure such as a hemisphere. In such a structure, it is necessary to reduce the weight of the entire structure as much as possible, and a lightweight material such as a film material is often used. The openable roof structure must open and close the closed roof structure which is originally completed as described above. In the conventional openable roof structure, a roof structure having a completed shape is appropriately cut and moved to open and close. Therefore, compared to a roof structure that does not open and close, the structure that opens and closes loses structural integrity, and significantly reduces the structural performance obtained from mechanical rationality.
As a result, the weight of the open / close roof structure had to be significantly heavier than that of the dome roof structure without opening / closing.

Further, in the case of a structurally integrated dome structure without cutting, even the stress offset inside the roof structure loses continuity due to cutting for opening and closing, so that it is all processed in the boundary structure. When the need arises, for example, the dome tries to open outward.
In addition, the traveling device for opening and closing had to be burdened.

[0007] In addition, the cutting of the roof structure has caused problems such as a rain break at the cut portion. Also, as described above, a tension structure using a membrane material or the like is often used in a large roof structure to reduce the weight, but in the case of a retractable roof structure, a large change in the roof shape is caused by opening and closing. As a result, mechanical continuity is also lost, and it has been considered difficult to use a tension structure, which needs to introduce tension over the entire roof surface, for an openable roof. Further, since the roof structure has a cut portion, the air film structure that needs to maintain the internal pressure has not yet been used, despite being the lightest structural system among the conventional structures.

In the openable roof structure according to the present invention, the boundary reaction force structure 1 composed of the upper frame 3 and the lower frame 4 that move relatively allows stable tension to be introduced to a lightweight roof surface. The reaction force is processed in the pair of frames 3 and 4. That is, due to a change in the shape of the connecting member such as the cable member 5 and the film member 6 due to the relative movement between the upper frame 3 and the lower frame 4, tension is introduced into the connecting member, and during this time, tension is introduced into the connecting member. Is always processed in the boundary reaction structure 1, so that the load on the traveling device for moving the frames 3 and 4 is slightly perpendicular to the weight of the frames 3 and 4. Only the tension component is provided, which significantly reduces the load on the traveling device. Further, after the roof surface is formed by the film material 6, the air is blown as a compressed material into the bag-like film surface having the twist pattern formed from the closed portion between the upper frame 3 and the lower frame 4, thereby being extremely limited. To achieve a lightweight roof structure.
