[0002]

2. Description of the Related Art Recently, for indoor athletics facilities, etc.,
Large fixed dome roofs have been adopted. As a structural type of the fixed dome type roof, there are known a steel truss structure including a single-layer truss and a multi-layer truss, a cable structure, and a structure in which the steel truss structure and the cable structure are combined. In such a fixed dome type roof, there is a roof having a membrane structure in which a roof finishing material made of a metal plate or the like is attached to the steel frame truss, or a membrane swelled by air filling is pressed by a cable structure.

[0003]

By the way, it cannot be denied that the fixed dome roof has a closed atmosphere even if it has a membrane structure. Therefore, in recent years, an openable roof structure has been developed. As this openable-closable roof structure, for example, one that opens and closes an opening of an indoor baseball field is provided, but since this opening is usually circular in plan view, its roof shape is also circular, Is divided into a pair of semicircular shapes to open and close the opening.

However, for example, a general athletic stadium or the like, which is provided with an annular track around it and is capable of playing ball games such as soccer and rugby, has a substantially rectangular shape in a plan view. When introducing a retractable roof structure into such a stadium, etc., if the circular roof is divided into a pair of semi-circular shapes, no matter whether the roof is slid or rotated, There is a problem that it is difficult to open the opening into an appropriate size and shape according to the type and the like. For example, it is difficult to open and close the opening in accordance with a soccer game in which only the central part of the ground is desired to be open, or an athletic game in which the entire ground including the surrounding tracks is desired to be open.

The present invention has been made in view of the above circumstances, and a retractable roof capable of opening and closing a rectangular or elliptical opening having a different length and width in plan view to have a desired size and shape. It is intended to provide a structure.

And a pair of first movable roofs movably provided in the major axis direction of the opening to open and close a part of the opening, and a pair of first movable roofs movably provided in the minor axis direction of the opening. It is provided with a pair of second movable roofs that open and close other portions other than a part of the opening opened and closed by the movable roof.

According to a second aspect of the present invention, there is provided the openable roof structure according to the first aspect.
In the above, the first movable roof is provided so as to be movable above the second movable roof and to be able to open and close the central portion of the opening.

According to a third aspect of the present invention, in the openable roof structure according to the first or second aspect, each rail for guiding the movement of the first movable roof and the second movable roof is along an arc having the apex of the roof as an apex. It is fixed to a steel beam that is installed.

[0009]

In the openable roof structure according to claim 1, the pair of first movable roofs is moved in the longitudinal direction of the opening to determine the length of the opening in the longitudinal direction, and Second
By moving the movable roof in the short axis direction of the opening,
Determine the minor axis length of the aperture. As a result, the opening is opened and closed in a desired size and area.

In the retractable roof structure of claim 2, the first movable roof moves above the second movable roof to open and close the central portion of the opening, thereby closing the second movable roof. The central part of the opening can be opened and closed while it is fixed.
In addition, the first movable roof and the second movable roof can be moved independently of each other, and in the plan view,
Since the movable roof and the second movable roof can be partially overlapped with each other, the opening can be opened and closed in various sizes and shapes.

According to another aspect of the present invention, there is provided a steel frame in which rails for guiding the movement of the first movable roof and the second movable roof are provided along an arc having the apex of the roof as an apex. Since it is fixed to the beam, the first and second
The movable roof opens and closes while drawing an arcuate trajectory, so that it is possible to shorten the protruding length to the outside as compared with a horizontally moving roof. Further, since the rails for guiding the movement of the first and second movable roofs are fixed to the steel beam, these first and second movable roofs are fixed.
Also, the second movable roof can be reliably supported.
