Field of the Invention The present invention relates to a connecting structure for a membrane, and more particularly to a connecting structure for a membrane in which the rigidity of the connecting portion of the membrane in the swinging direction is reduced.

いる。2. Description of the Related Art In recent years, there has appeared a structure in which a roof of a large space facility or the like having a pillarless structure such as a dome is constructed as a membrane roof. This membrane roof is formed of a waterproof flexible membrane, and covers the upper end of the outer wall surrounding the large space facility. The membrane roof is inflated (expanded) by injecting air into the inside of the facility, and a dome-shaped roof whose central portion is expanded in this inflated state is formed. The inflated membrane roof is supported by cables stretched at appropriate intervals.

分離してしまうのを防止できるようになっている。Since the membrane roof needs to continuously cover large space facilities, the area of the membrane roof becomes significantly large. Therefore, this membrane roof connects a plurality of membrane bodies cut into a predetermined shape to each other. The whole is formed. At this time, the connection between the film bodies is performed via a connection fitting as disclosed in, for example, Japanese Utility Model Publication No. Hei 2-24857 (E04H 15/54). That is, the connection fitting includes inner and outer presser members disposed on both sides of the film member so as to straddle between the connection ends of the film member. It is configured to be tightened via a nut. Then, the connection end portions of the film body are sandwiched between the presser fittings,
Even when a large tension acts on the film body, it is possible to prevent the connection portion from being easily separated.

課題があった。However, in such a conventional connection structure for a film body, a bolt and a nut are tightened with the connection end of the film body to be connected between the inner and outer presser fittings sandwiched therebetween. Therefore, the connection between the film bodies is performed in a rigidly connected state. Therefore, when the film roof is fluttered and the angle between the film members connected to each other is changed, the respective film members are swung about both side edges of the inner and outer presser foot. The bending is repeated locally at this edge portion. For this reason, the fatigue occurs in the locally bent portion of the film body, and the film body is easily damaged in the portion,
As a result, there is a problem that the durability of the film body is significantly reduced.

It is an object of the present invention to provide a connection structure of a film body that can be used.
