[0002]

2. Description of the Related Art Conventionally, a simple roof structure used for outdoor rain protection and sun protection uses a metal frame material or a suspension material, and an awning is stretched by supporting it. There is a structure that was constructed, which is to assemble a frame material when needed, and to put an awning on it,
When not in use, the awning is removed and the frame material is disassembled and stored.

Further, as the openable and closable roof structure, a plurality of roof structures obtained by dividing a dome-shaped roof into a plurality of roofs are used, and the rails installed on the upper end portions of the side walls of the building are each movable and divided. There is a structure in which the roofs are opened by storing the roof structures on one side so that the roof structures overlap each other in a vertically overlapping arrangement.

Further, there is also a structure using an awning as an opening / closing roof structure. This kind of opening / closing roof structure is hung on a pair of rails installed on both side walls of a building so as to be independently movable in parallel. A large number of beam members are installed, the awning is fixed to the beam members, and the awnings are expanded and stretched by moving the beam members in parallel in a direction in which they are separated from each other. There is a structure in which the awning is folded to one side and folded up by moving it in one direction and moving it to one side so that the roof is opened.

[0005]

The above-mentioned conventional structure in which the skeleton is assembled by assembling the skeleton when needed, is easily installed if the skeleton can be manually assembled or disassembled. It can be installed and dismantled, but with large ones such as several hundred square meters, the skeleton and awning become large, large heavy equipment and many workers are required for installation and dismantling, and opening and closing at short intervals It is not suitable for the required roof structure. Also, the conventional structure that uses a plurality of roof structures obtained by dividing the roof into multiple parts and slides them horizontally to open and close is useful as a roof structure for a permanent building. However, it is disadvantageous in terms of cost and unsuitable when it is disassembled after being used for a certain period of time, for example, several months to several years, and then reused at another place.

Further, in the case of the conventional structure in which the awning is supported by a plurality of beam members and moved, the structure is simple, but it is self-supporting between the rails due to the bending resistance of the beam members themselves. Since it is hung over, the beam cross section is large,
The longer the span, the larger the beam cross section, the larger the roof material storage space required when the roof is opened, the more the opening space is restricted, and the installation and dismantling become difficult.

In view of the above-mentioned conventional problems, the present invention can be easily opened and closed, has a small roof material storage space when the roof is opened, has a large open ratio, and has a super-span installation or disassembly. The purpose is to provide a temporary membrane opening / closing roof structure that can be easily and inexpensively used, and does not have a cost disadvantage even if it is dismantled or relocated after being used for a short period of several months.
