Description

Description: TECHNICAL FIELD The present invention relates to a roof structure, and more particularly to a retractable roof that can be partially opened and closed depending on the weather.

《Prior art》 Recently, all-weather stadiums have attracted attention. Among them, focusing on the problems of the air film structure, part of the roof is partially opened and closed according to the weather, and natural lighting is provided during sunny weather. The applicant has proposed various retractable roofs so that ventilation is possible and driving competitions can be performed even in rainy weather. JP 61-1695
40, JP-A-61-169541 and JP-A-62-236939.

In each of these, the floor area of the building was very small compared to the site area, and we were thinking of a retractable roof that can be applied to things where there is no room on the site.

<Problems to be solved by the invention> Narrative In the conventional retractable roof, there was no room in the site area, so the aperture ratio had to be sacrificed to some extent.

It is an object of the present invention to provide a retractable roof in which a sufficient opening ratio can be obtained when the site area has a margin, and the site portion with a margin can be used in some way.

<< Means for Solving the Problem >> In order to achieve the above object, the retractable roof of the present invention covers an opening formed from a lower side portion to a top portion of a building having a substantially circular flat sectional shape. A retractable roof, covering the lower side of the opening, and moving along the building so as to overlap the fixed roof arranged on one side of the building to move the lower side of the opening. A lower movable roof that opens and closes, and a horizontal movable roof that is provided separately from the lower movable roof, covers the top of the opening, and slides in the horizontal direction to open and close the top of the opening. It is composed of and. Further, in order to reduce the weight of the horizontally movable roof portion, maintain its shape, and facilitate handling, the horizontally movable roof integrally connects a plurality of bag-shaped membranes,
In addition, it is a double film that shares air through through holes that allow air to pass through each other.

《Operation》 It is possible to obtain a sufficient opening by moving only the top of the roof horizontally and rotating the lower part if necessary. In the case of a dome type roof, it is difficult to move the lower part horizontally because the lower part of the dome has bleachers. Therefore, in the horizontal movement type, leaving the bleachers and other equipment as they are,
The roof configured to cover all of these is moved horizontally, but if only the top is moved horizontally in this way, there is no need to perform horizontal movement for each large roof that covers the entire building. There is. When further opening the surroundings of various facilities, the lower part of the roof configured to cover the bleachers is opened and closed as a rotary movement type.

For the horizontally movable roof part, if air with some pressure is sent to the arbitrary bag-shaped place, this air becomes bag-shaped through the through holes passing between the bag-shaped membrane members. The membrane roof is made up of a double membrane that extends through the membrane.

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

This openable dome roof 1 has a horizontally movable roof 5 in which the top of a base leg 3 straddling two rails 2-2 installed in parallel so as to sandwich both sides is made up of a double membrane 4 and the lower part is rotated left and right. And a pivoting movable roof 6 that opens.

The base 3 has a shape in which a semi-circular frame top is hollowed out in a circular shape, and a double membrane is stretched on the top, and the base is supported on a rail 2-2 by a trolley. FIG. 1 shows a state in which the dome roof 1 is closed, and when it is opened, it becomes as shown in FIG. That is, the length of the rails 2, 2 is at least the length at which the horizontally closed movable roof 5 ends moving to the outside of the dome roof 1, and corresponds to the diameter of the dome roof 1 from the outer peripheral end surface of the dome roof 1. It is attached to the horizontal movable roof 5 by an extra length in the moving direction. The horizontally movable roof 5 opens and closes by moving a dolly 7 at the base of the pedestal 3 and horizontally moving the top of the dome roof 1.

The pedestal 3 is not a semi-arcuate shape that is integrally formed so as to straddle the rails 2 and 2, but supports an annular beam 8 having a radius required to cover the top of the dome roof 1. The annular beam 8 may be provided with the double film 4, which is shown in FIG. In such a structure, the bottom surface of the annular beam 8 is in close contact with the top of the rotary roof 6 to close the gap.

Half of the dome roof 1 that constitutes the lower part and is placed on the outer wall 9 is the fixed roof 10.
FIG. 4 shows the details of the rotary movable roof 6 and the double membrane 4 which move in the outward direction of 10.

The rotary movable roof 6 may have a semi-circular shape, but in this embodiment, the membrane material 12 is stretched on the surface of the main frame 11 that spreads at a 90 ° angle so as to open toward the fixed roof 10. At the base of the main frame 11, rails 13 attached to the top surface of the outer wall 9 are attached with wheels 14 which can travel freely, and an inner ring provided so as to overlap with the lower side of the ring beam 8. The beam 15 is supported by a column 16, and a rail 17 provided on the outer peripheral surface side of the inner annular beam 15 rotatably supports the upper part of the main frame 11 of the rotary movable roof 6.

On the other hand, the horizontally movable roof 5 is formed by forming a bag-shaped film into a hemispherical shape and connecting the through holes 18 to each other at the connecting portion.
The air is made to flow through each other, and if compressed air is sent to one place, it will be spread throughout the through hole 18. An air duct and 19 are provided inside the annular beam 8 for passing air compressed to a pressure slightly higher than the normal pressure, and from this duct 19 in the middle of the flexible pipe 20 desired in any part of the double membrane 4. Check valve 21
Is provided.

Therefore, if air having a slightly higher atmospheric pressure is sent to the duct 19, this air is sent through the check valve 21 into the double membrane 4, and the double membrane 4 expands to a predetermined shape.

<Effect> As described in detail above, according to the retractable roof of the present invention, since the lower part is the rotationally movable type and the top part is the horizontally movable type, the roof has a horizontal movement type compared to the entire roof. Since only the top part moves horizontally, the moving part can be kept as small as possible, and at the same time the visibility of the space that receives this horizontally movable roof part is improved and the horizontally movable roof part can be moved. When you do this, it is convenient to avoid direct sunlight underneath. Further, a sufficient opening ratio can be obtained by opening the rotary movable roof part.

Further, the horizontally movable roof is a double-layered membrane having a bag-like structure, and the whole is integrally connected with a plurality of small membranes having a bag-like structure, and is provided with through holes through which air flows. Since it has been made considerably lighter, the structure that supports it has become easier in terms of strength, and the movement power capacity is also small. Further, even when the air pressure becomes insufficient or the air amount becomes small, the shape of each is relatively small, so that the overall shape is maintained and the handling becomes easy.
