Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a retractable roof capable of partially opening and closing a central portion such as a dome roof depending on the weather.

《Prior art》 Recently, all-weather stadiums have attracted attention, and part of the roof is partially opened or closed depending on the weather, allowing natural daylight ventilation in fine weather, and closing the roof in rainy weather The retractable roof, which has been designed so that it can be used, is drawing attention.

Then, in order to realize a large span structure that can be applied to a baseball field even in the scale of a building equipped with this openable roof, an air film or suspension film structure, a rotary slide type roof, a horizontal stacking slide type or a vertical slide type A retractable roof with a large span frame structure that allows a large opening ratio has been proposed.

These retractable roofs open the opening by storing the movable roof in a fixed roof with a small horizontal projection area, and when closing the opening, move the movable roof that was stored in the fixed roof to the opening. By opening the opening, the opening can be opened and closed arbitrarily.

<< Problems to be Solved by the Invention >> Therefore, the problem is to protect the housed movable roof and to make the movable mechanism of the movable roof easy to maintain. That is, the purpose of constructing a retractable roof is to open the roof in order to obtain as natural a state as possible, and it is natural to keep the roof open normally. Protecting the movable roof, which fits in the open state, has also become an important issue.

The present invention has been made in view of the above circumstances, and an object thereof is to provide sufficient protection of a movable roof and an aperture ratio that facilitates its maintenance without significantly changing the basic structure of a conventional retractable roof. To provide a high retractable roof.

<< Means for Solving the Problems >> In order to achieve the above object, the retractable roof of the present invention is:
An openable roof that opens or closes an opening of a building by slidingly moving a plurality of movable roofs divided into at least two steps, and a fixed roof is provided at one side edge of the opening. Below the roof, beams are extended at intervals equal to or greater than the thickness of the movable roofs stacked along the movable direction of the movable roofs, and the movable roofs are divided into two or more steps. Among the movable roofs, the movable roof located on the fixed roof side is moved on the beam so that the other movable roof overlaps and is stored under the fixed roof in the overlapped state. Further, in order to increase the opening ratio, it is preferable that the fixed roof is arranged so as to surround the opening, and the movable roof divided is moved radially from the position where the opening is closed to open the opening. For the purpose of facilitating maintenance such as waterproofing, the movable roof is a two-tiered stack, and the second movable roof located above is along the guide rail laid on the surface of the first movable roof. Superimpose.

<< Operation >> According to the retractable roof of the present invention having the above-described configuration, in order to open the opening of the building, the movable roof located on the fixed roof side among the plurality of movable roofs divided into at least two steps or more is used. The movable roof is slid on the upper surface so that other movable roofs overlap each other, and the movable roofs are housed under the fixed roof in an overlapped state.

By thus storing the movable roof below the fixed roof, it is possible to reduce the floating of the movable roof due to wind pressure, and it is possible to downsize the device for preventing this floating.

Further, since the beams are extended below the fixed roof with an interval equal to or larger than the thickness of the movable roofs stacked, a space for accommodating the plurality of movable roofs stacked below the fixed roof is secured. In addition, since the beams will not be visible from outside the fixed roof, the appearance of the building will not be impaired.

A higher aperture ratio can be obtained by disposing the fixed roof around the opening and moving the movable roof radially from the position where the movable roof closes the opening to open the opening.

Furthermore, if the movable roofs are stacked in two layers and the second movable roof located above is superposed along the guide rails laid on the surface of the first movable roof, the movement of the movable roof will be smoother. Therefore, it is possible to stabilize the opening and closing work of the openable roof.

<Example> Hereinafter, a preferred example of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a case where a dome is formed by a retractable roof applied to the present invention. The openable / closable dome roof 1 has a side wall 3 standing on the ground. Further, there is provided a donut-shaped fixed roof 9 in which the outer peripheral portion is supported by the outer peripheral annular beam 5 at the upper edge of the side wall 3 and the inner peripheral portion is supported by the inner peripheral annular beam 7.

Further, the opening portion on the inner peripheral surface side of the fixed roof 9 is covered with the upper movable roof 11 and the lower movable roof 13 that are vertically stacked. The outline plane shape is divided into three concentric circles from the center of the dome roof 1 in the outer diameter direction, the outermost periphery of which is the fixed roof 9, and the remaining two steps are further divided into a fan shape at intervals of 60 degrees from the center of the dome. It is configured as a defined triangle, which is divided and overlapped in the circumferential direction, and the center side of the dome is the movable roof 11 on the upper second stage, and the fixed roof side is the movable roof 13 on the lower first stage. It is a thing.

Arch beams 15 are provided radially from the center of the dome roof 1 at an angle of 60 degrees in the outer diameter direction. The arch beams 15 are arranged below the fixed roof 9 with a space equal to or larger than the thickness of the movable roofs 11 and 13 of the upper second stage and the lower first stage stacked.
The movable roofs 11 and 13 are extended along the movable direction. The movable roof 11 of the second stage and the movable roof 13 of the first stage are supported by arch beams 15 at the center in the diametrical direction and by guide rails 17 provided at the lower layer positions from the outer peripheral end.

That is, as shown in FIG. 2, the second movable roof 11 can be freely run on the first movable roof 13 so that the first movable roof 13 can travel.
The movable guide roofs 11 and 13 having the two-stage structure supported by the guide rails 17 above the guide rails 17a laid on the joint beam 23 that is provided between the outer peripheral annular beam 5 and the inner peripheral annular beam 7. It is designed to move upward. The fixed roof 9 is the above-mentioned outer ring beam 5,
It is supported by a bundle 21 erected on the inner peripheral circular beam 7.

The movable roofs 11 and 13 are stored under the fixed roof 9 when the opening 19 is opened, and from there, the guide rails 17b laid on the arch beams 15 move to above the opening 19, and thus the opening 1
Block 9

When the second movable roof 11 and the first movable roof 13 are housed under the fixed roof 9, the opening 19 is completely opened, and the housed state is shown in FIG. The arch beam 15 is integrally connected so as to intersect with the inner peripheral annular beam 7, and the base end portion thereof is connected to the outer peripheral annular beam 5. A guide rail 17b for moving the movable roof 13 of the first stage is laid on the surface of the arch beam 15, and the base end of the arch beam 15 is sandwiched from both sides with a certain distance. A joint beam 23 is provided between the outer peripheral annular beam 5 and the inner peripheral annular beam 7 while keeping a distance, and a guide rail 17a is laid on the surface of the joint beam 23. Then, a ring-shaped lattice 25 assembled in a ring-shaped lattice so as to cover the upper surfaces of the inner peripheral annular beam 7 and the outer peripheral annular beam 5 is erected on the inner peripheral annular beam 7 and the outer peripheral annular beam 5, respectively.
We support at 21.

The fixed roof 9 is formed by applying a film material formed of carbon fiber woven cloth or the like on the surface of the ring-shaped lattice 25.

The second movable roof 11 is supported by three points of a guide rail 17 laid on the surface of the first movable roof 13 and a guide rail 17b laid on the surface of the arch beam 5, while the first movable roof 13 is supported.
When the opening 19 is moved up and down and the opening 19 is opened, it is superposed on the surface of the movable roof 13 of the first step, and the movable roof 13 of the first step is further directly connected to the guide rail 17a and the arch beam 1 laid on the joint beam 23.
It fits under the fixed roof 9 while being supported by three points of the guide rail 17 of 5.

<Effect> As described in detail above, according to the retractable roof of the present invention, the fixed roof is formed at one end of the building, and the movable roof is housed under the fixed roof to obtain the opening portion. There is an effect that can be protected from wind and snow. In addition, the fixed roof surrounds the central opening of the building, and the opening is obtained by accommodating the movable roof that is superposed so that it overlaps from the position where the central opening is closed, so that the opening is obtained. The radial length of the roof is relatively short, and the radial length of the fixed roof that houses the roof is also short, so that the aperture ratio can be increased. Furthermore, when this movable roof has a two-stage structure, the movable devices such as the guide rails on the surface of the movable roof of the first stage are repaired and inspected and rust-proof when the movable roof is stored under the fixed roof. It has an effect that it can be easily processed. In addition, not only does the guide or support device for mounting the moving roof on the surface of the fixed roof unnecessary in appearance, but the surface of the fixed roof is cluttered by mounting the movable roof on the fixed roof. Avoiding the feeling of getting rid of and getting a clean look,
Further, it is also advantageous in that the structural consideration for resisting the lift force due to the wind received by the movable roof located on the fixed roof is not required.

Further, since the beams are extended below the fixed roof with an interval equal to or larger than the thickness of the movable roofs stacked, a space for accommodating the plurality of movable roofs stacked below the fixed roof is secured. In addition, since the beams will not be visible from outside the fixed roof, the appearance of the building will not be impaired.

A higher aperture ratio can be obtained by disposing the fixed roof around the opening and moving the movable roof radially from the position where the movable roof closes the opening to open the opening.

Furthermore, if the movable roofs are stacked in two layers and the second movable roof located above is superposed along the guide rails laid on the surface of the first movable roof, the movement of the movable roof will be smoother. Therefore, it is possible to stabilize the opening and closing work of the openable roof.
