Description

TECHNICAL FIELD The present invention relates to a retractable roof suitable for an all-weather building where the roof opens and closes like an athletic stadium.

<Prior Art> Conventional open / close type roofs each have a laminated structure in which the roofs are stacked in several stages, and these are slidably slid or run to open / close the top of the building.

For example, a beam or a girder supporting a roof is configured to be extendable and retractable, or traveling wheels are attached to the girder to run on the beam.

<Problems to be solved by the invention> However, in the conventional roof, since the space for accommodating the open roof part remains at the top, considering the opening ratio in the horizontal projected area of the roof, the roof opening Rate 100
It could not be set to%.

Therefore, according to the present invention, when the roof is opened, since the roof member is positioned substantially vertically, the horizontal projected area required for storage is minimized, and opening / closing with an opening ratio of 100% is sufficient to withstand the influence of cross wind at that time. The purpose is to provide a roof.

<< Means for Solving Problems >> In order to achieve the above object, the retractable roof of the present invention is a quadrangular pyramid, a triangular pyramid, a cone, a dome-shaped roof, and a radial cut reaching from the center to the periphery. A plurality of fan-shaped roof members that are formed by being divided along the line and are formed so that they can move up and down with the peripheral end side base end as a rotation axis, and these roof members are erected to open and collapse the roof. And a lifting means for lifting and lowering these roof members to close the roof. Further, each of the roof members is formed such that a middle portion thereof in the height direction can be folded in the middle, and the middle portion can be bent and stretched. It is characterized in that it is provided with a bending and stretching means for performing a center folding operation.

<Operation> When the roof moves from the closed state to the open state, the roof member pivotally moves in the elevation direction so that the central portion when the roof is closed is lifted upward by the elevation means so that the roof end is the center. Then, it becomes almost vertical and stops. Then, the roof member in the opened state is bent from the middle part in the height direction by the bending and stretching means, and the height of the roof in the opened state becomes about ½.

<Examples> Hereinafter, preferred examples of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a building having a dome roof 1 in the shape of a hemisphere, and this building has the dome roof 1 placed on an outer wall 3 standing in a circle on a ground surface 2.

The dome roof 1 has a structure in which it is radially cut down at intervals of 60 degrees from the center point of the top of the roof and is divided, and each fan-shaped roof member 4-
4a-4b-4c-4d-4e.

Each roof member 4 to 4e is a frame 6 in which a lightweight steel frame is assembled in a lattice.
It is covered with a thin metal plate or a fluororesin film.
Furthermore, the middle part in the height direction of each roof member 4 to 4e is a flexible hinge and is bent inside the building.

There is a ground 8 in the center of the inside of the building, and a stand 9 surrounds the outer circumference.

That is, the dome roof 1 has a hemispherical shape in a closed state, but when the dome roof 1 is opened, each roof member 4 to 4e is rotated in the elevation direction with the base end located on the outer wall 3 side as a rotation axis. The roof opens from the roof top in six directions (Fig. 2), and after that, as shown in Fig. 3, the roof members 4 to 4e act to bend inward from the middle part in the height direction where the roof members 4 to 4e open, increasing the opening ratio and opening the roof. The area where the members 4 to 4e receive the wind pressure is reduced.

Note that the skeleton of the roof members 4 to 4e is not limited to metal and may be a composite material of plastic and metal, and it is desirable to reduce the weight.

Next, since the roof members 4 to 4e have the same structure,
One of them is illustrated in detail in FIG. Each of the drawings is a side view relating to only the roof member 4, and the outside of the outer wall 3 forms an inclined surface 10 that descends outward from the top thereof, and further the inclined surface 1
A base end 11 of the roof member 4 is pivotally supported by a hinge 12 on the outer edge of the top of the roof member 0.

The middle part of the roof member 4 is bent in a free hinge 13 so that the top is the upper roof material 5 and the base is the lower roof material 7. That is, the roof member 4 has an upper roof member 5 and a lower roof member 7 each formed of a frame 6, and the upper and lower roof members 5 and 5 are formed.
7 is connected by a flexible hinge 13.

On the joint surface of the upper roof material 5 and the lower roof material 7 which are connected and connected by the flexible hinge 13 and the front end surface of the roof member 4, connecting tools 14 for the roofs are installed, respectively, for waterproofing and safe connection. Are considering.

As the connecting tool 14, the actual application of the applicant's earlier application Sho6
No. 0-161309 is preferable. This is a sickle lock on one side,
The other is provided with a lock hole to be engaged therewith, and the lock holes are connected to each other in a pulled state.

The rotational movement of the roof member 4 at the base end 11 and the bending movement of the roof hinge 13 are performed by the following structure.

A hydraulic cylinder 15 as a lifting means and a hydraulic cylinder 17 as a bending / extending means are used for driving power. One end of the first cylinder 15 is rotatably supported inside the top of the outer wall 3, and the tip of the cylinder rod 16 thereof is rotatably supported at a position slightly above the base end 11 of the lower roofing material 7.

When the hydraulic pressure of the first cylinder 15 is controlled and the cylinder rod 16 is expanded and contracted, the roof member 4 reciprocally rotates in the elevation direction with the hinge 12 of the base end portion 11 as a rotation axis.
Since the base end portion 11 escapes in the inclination direction by the inclined surface 10 during the elevation movement, the tip of the roof member 4 which bends inward due to the curved curvature surely moves to the outside of the stand 9 and has an opening ratio of 100%. can get.

In the middle of the roof member 4, one end of the second cylinder 17 is pivotally supported slightly below the joint between the upper roof material 5 and the lower roof material 7, and the tip of the cylinder rod 18 thereof is attached. A sickle-shaped bracket 20 is pivotally mounted between the cylinder rod 18 and the base of the upper roof member 5.

When the cylinder rod 18 is extended, the bracket 20 pivots forward with the hinged hinge 13 as a pivot, and as a result, the upper roofing member 5 bends inwardly of the building so as to bend forward. When the cylinder rod 18 is contracted, the reverse operation is performed and the upper roof material 5 returns to the vertical state.

The descriptive bracket 20 transmits the linear movement of the cylinder rod 18 to the upper roofing member 5 and interlocks with it. That is, since the force of the second cylinder 17 is transmitted to the upper roof member 5, the shape of the bracket 20 is such that the center of the tip shaft attachment portion of the cylinder rod 18 always moves outside the axis of the hinge 13. Anything can be used.

Therefore, a bracket 22 as shown in FIG. 5 is also conceivable. The side surface of the bracket 22 is formed in a hook shape, the bent portion of the bracket 22 is pivotally supported by the shaft of the free hinge 13, and the cylinder rod 18 is axially attached to the end of the short extension end 24, while the long rod is long. The extended end portion 25 is pivotally attached to an intermediate position of the upper roofing material 5.

According to the above bracket 22, contrary to the case of the bracket 20, the upper roof member 5 maintains the vertical position at the position where the cylinder rod 18 is extended, and the flexible hinge 1 is at the contracted position.
The upper roofing material 5 is bent inward with 3 as a rotation axis. The point of action of this bending and stretching movement is the base of the upper roofing material 5 (fourth
The stress applied to the frame 6 is relatively small because it is not the case (in the figure) but the intermediate position.

<Effect> As described in detail above, according to the retractable roof of the present invention, the roof is opened by vertically moving the base member so as to vertically elevate the roof member so that the roof member is opened. The horizontal projection area is minimized when it is cut, and the aperture ratio is 100%.
Can be Therefore, the feeling of openness can be made almost the same as in the state without the roof. Further, since the retractable roof of the present invention does not have a step unlike the conventional multi-layer structure, a flat roof surface without a step can be obtained when the roof is closed. It is advantageous in that there is no need to take care of rain. Regarding the problem of wind blowing, it is necessary to prevent the blowing by some kind of closing means in the conventional roof having stepped portions, but in the present invention, such a consideration is not necessary because a flat roof surface can be secured. effective.

Furthermore, when the roof member is erected and the roof is opened, the middle part of the roof member can be folded inward, so the area that receives cross winds can be reduced, and the height of the erected roof member must be low. Since it is possible to reduce the structure for wind pressure resistance while being preferable in terms of wind pressure resistance and landscape,
It has the excellent effect of reducing the design strength of the surrounding structure such as the foundation that supports the roof.
