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-mentioned object, the retractable roof of the present invention has a quadrangular pyramid, a triangular pyramid, the peripheral side base end of which is supported by a support base.
A plurality of roofs, such as a cone and a dome, are formed by dividing the roof along a radial cutting line that extends from the center to the peripheral side, and are vertically movable with the peripheral side base end portion as a rotation axis. A fan-shaped roof member, and a lifting means for lifting and lowering the roof members to raise and lower the roof members and close the roof members by closing the roof members. It is characterized by having means.

<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 moved downward together with the support frame by the driving means to lower the height of the roof, so that it is possible to reduce the influence of wind hit and the shadow.

However, the support base may be moved up and down in parallel with the elevation movement of the roof member. In this way, the time required to open and close the roof becomes shorter.

<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.

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

That is, the dome roof 1 has a hemispherical shape in the closed state, but when it is opened, the roof members 4 to 4e are rotated in the elevation direction with the base end supported on the outer wall 3 side as a rotation axis. It opens from the roof top in six directions (Fig. 2), and after that, the roof members 4 to 4e move downward together with the supporting frame 3'supporting the base end thereof as shown in Fig. 4 to lower the opened height. The area of the roof members 4 to 4e that receives the wind pressure is reduced.

Further, for the purpose of lowering the height of the dome roof 1, as shown in FIG. 3, the ground surface 2 is dug down to lower the portion supporting the building and its surroundings.

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. That is, the drawing is a side view relating only to the roof member 4, and a part of the outer wall 3 is configured as a supporting frame 3'for supporting the base end portion of the roof member 4, and this supporting frame 3'is formed on the outer wall 3. Inserted hole 2
It is arranged so that it can move up and down in 0, and is moved up and down by a pneumatic jack, a hydraulic jack or a hydraulic cylinder 10 as a drive means installed at the bottom of the fitting hole 20.

In the hydraulic cylinder 10, the speed at which the cylinder rod moves up and down and the vertical movement can be switched between two stages and three stages by a hydraulic circuit so that the stop height can be selected.

The base end of the roof member 4 is rotatably supported by a hinge 12 as a hinge mechanism on the outer edge of the top of the vertically movable support frame 3 '.

The roof member 4 can perform a depression / elevation motion with the hinge 12 as a rotation axis. When the roof member 4c is rotated and tilted in the depression direction, the roof member 4c is in contact with the tip of the roof member 4c at the opposite position. Since it is desirable that the abutting portions are engaged in a watertight manner so as not to be easily disengaged, a connecting tool 14 is provided.

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 hinge 12 is as follows.

A hydraulic cylinder 16 is used for the driving power as the elevation means. One end of the cylinder 16 is rotatably pivoted at a position slightly above the hinge 12 at the base end of the roof member 4 and the tip of the cylinder rod 18 is rotatably supported on the top of the pedestal 3 '. Are provided.

When the hydraulic pressure of the hydraulic cylinder 16 is controlled and the cylinder rod 18 is expanded and contracted, the roof member 4 is fixed to the hinge 1 at the base end thereof.
It reciprocally rotates in the elevation direction with 2 as a rotation axis. Since the base end part escapes to the outer peripheral surface side of the outer wall 3 during the elevation movement, the tip of the roof member 4 that bends inward due to the curved curvature surely moves to the outside of the stand 9, and an opening ratio of 100% is obtained. To be

Since the mounting position of the hinge 12 affects the aperture ratio of the dome roof 1, it is preferable that the hinge 12 is mounted between the inside of the base end of the roof member 4 and the top of the support frame 3'on the outer peripheral side.

Further, it is sufficient that only the part to which the hinge 12 is attached is the part that moves up and down of the support frame 3 '. Therefore, as shown in FIG. 4, a piston-shaped supporting base 3 ', which should also be called a movable outer wall, is used.
After the hydraulic cylinder 10 is installed in the bottom of the fitting hole 20 formed in a part of the outer wall 3, the hydraulic cylinder 10 is loosely fitted so as to be vertically movable.

Of course, this changes the height of the dome roof 1,
Each of the roof members 4 to 4e is rotated in the elevation direction and lowered from the opened state to reduce the resistance to cross wind.

However, the roof members 4 to 4e are rotated in the elevation direction by the hydraulic cylinders 10 and 16, respectively, so that the dome roof 1 can be opened and closed and vertically moved.

<Effect> As described in detail above, according to the retractable roof of the present invention, the roof is opened by raising and lowering the peripheral side base end portion of the roof member as a rotation axis so as to vertically erect the roof member. , The horizontal projected area becomes the minimum when fully opened, and the aperture ratio is 1
It can be set to 00%. 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 supporting base can be moved downward by the driving means,
The area that receives cross winds can be reduced, and the height of the standing roof member can be reduced, which is preferable in terms of wind pressure resistance and landscape, and the structure for wind pressure resistance can be reduced, which allows the roof to be reduced. It has an excellent effect that it can also reduce the design strength of the surrounding structure such as the foundation part that supports the.
