“Prior Art” In general, a roof is provided above a building to prevent rain and snow from entering the building, and also has a function of blocking direct sunlight. Such roofs are covered with beams as roofing materials (roofing materials) as the span of buildings increases.
In addition to the structure for supporting the structure, a shell structure, a film structure, a suspension structure, or the like is often applied.

By the way, in the case of a so-called arcade where this kind of roof is provided on the upper part of the sidewalk such as a shopping street, in addition to the original purpose such as awning and rain protection, like the outdoor sidewalk,
It is required to give consideration to the brightness and the feeling of liberation, and consideration of fire extinguishing activities in a fire and smoke emission is also one of the important matters in building an arcade.

Conventionally, this type of arcade is a beam material that extends in the width direction of the sidewalk on a substructure consisting of columns that are erected at intervals along the longitudinal direction of the sidewalk and beams that are erected between the columns. In general, the beam material is used to support the roof material, and the roof is fixed to the lower structure that supports it.

"Problems to be solved by the invention" With such a conventional arcade structure, the roof constituting the arcade is fixed to the lower structure, so that the user is anxious about strong sunlight or rain. It is not necessary, but there is a problem that needs to be solved, such as lack of brightness and feeling of openness, compared to outdoor sidewalks.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an openable and closable roof that can create a space with brightness and a sense of openness in an internal space covered by a roof. is there.
