[0002]
[Prior art]
2. Description of the Related Art In recent years, as a spatial building including an event venue, a public facility, and an indoor stadium, a membrane structure building such as a so-called dome structure and a tent structure has been actively constructed.
[0003]
In these membrane structures, there are many structures in which the roof surface can be opened and closed so that a lighting and an open feeling can be obtained. For a structure that allows the roof surface to be opened and closed, for example, in a relatively large-scale membrane structure, a method in which a part of the entire roof frame can be opened and closed by sliding is often used, but a relatively small-scale structure is used. In the membrane structure, a cable wire is stretched, and the cable material is used as a guide so that the membrane material can be opened or closed by expanding or folding, or a membrane material is stretched between the frame structures arranged in parallel, and 2. Description of the Related Art In many cases, a system in which a frame material can be opened and closed by expanding or folding it by making it possible to run a frame is adopted.
[0004]
[Problems to be solved by the invention]
However, as described above, in the case of a structure in which the roof surface can be opened and closed by expanding or folding the membrane material, the folded position of the membrane material is not uniform when the roof surface is open (when the membrane material is folded and stored). There are problems that the appearance of the film becomes poor and that the film material is unfolded in a pleated state, and that the film material is unfolded, which may damage the film material.
[0005]
Accordingly, a main object of the present invention is to provide a membrane structure in which a roof surface can be freely opened and closed by unfolding or folding a roof membrane material so that the roof membrane material is always neatly folded, and the membrane material is folded and stored. An object of the present invention is to prevent the aesthetic appearance in the state from being impaired and to prevent the film material from being damaged.
