Abstract

PURPOSE:To ensure a large sky factor under an open state by dividing a movable roof at mutually different stepped shapes while movably supporting the movable roof onto a guide rail laid at a stepped section formed to the roof peripheral surface in lower structure. CONSTITUTION:Curved surface-shaped fixed roofs 1, 2 are disposed at both ends of a roof section while curved surface-shaped movable roofs 3a, 3b, 3c divided in a stepped shape are arranged among both roofs 1, 2. These movable roofs 3a, 3b, 3c are supported movably on guide rails 5a, 5b, 5c laid at a stepped section formed to a roof peripheral surface in lower structure 4. The movable roof 3b of an intermediate section is disposed so as to be positioned on the side upper than the fixed roof 1. Accordingly, the height of the positions of the guide rails of each movable roof are changed in conformity with the shapes of stands, thus ensuring a large sky factor.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a retractable roof structure for a covered stadium, etc., which allows the inside of the stadium to be opened to the outside when the weather is good.

(Prior art) This type of structure that has been proposed in the past includes a method in which a plurality of movable roofs are moved on a linear track on a substructure, a method in which a plurality of movable roofs are rotated along a circular track, and a method in which a plurality of movable roofs are moved on a linear track. A system that combines a system that moves the movable roof and a system that rotates and moves it along a circular track (problem to be solved by the invention) In the conventional retractable roof structure described above, the track section of each movable roof is Because the movable roof is configured to open and close at the same level, a lower structure with a high height and uniform height to support the track is required, regardless of the purpose of use of the internal space. Become. In addition, when the roof is open, the lower structure obstructs visibility, so the sky factor (s
ky factor) becomes smaller.

The present invention has been proposed in view of the problems of the prior art described above, and its purpose is to provide a retractable roof structure that ensures a greater sky coverage when the roof is open.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the retractable roof structure according to the present invention has two fixed roofs each having a curved surface facing each other, and a movable roof having a curved surface disposed between the two fixed roofs. In a building with a retractable roof, the movable roof is divided into a plurality of different stages, and each movable roof is placed on a guide rail laid on a stepped portion formed on the circumferential surface of the roof in the lower structure. It is configured to be movably supported.

(Function) As described above, the retractable roof structure according to the present invention has a plurality of movable roofs that are arranged between fixed roofs having curved surface shapes facing each other, and that is divided into a plurality of different stepwise shapes. The roof surface can be opened by moving it along a guide rail laid on a step formed on the surface and storing it in an overlapping state on the fixed roof side.

Further, the roof surface is closed by moving each of the movable roofs along the guide rails in a direction away from the fixed roof.

At this time, by changing the level of the guide rails of each of the movable roofs installed at the stepped portion of the lower structure of the roof circumferential surface according to the shape of the stand, it is possible to ensure a large sky ratio and to increase the spatial volume. can be kept to a minimum.

(Example) Hereinafter, an illustrated example in which the present invention is applied to an all-weather stadium will be described.

(1) and (2) are curved fixed roofs installed at both ends of the roof. (3b)
(3c) is arranged, and the guide rail (5a
) (5b) is movably supported on (5c).

The movable roof (3b) in the middle part is arranged above the fixed roof (1). i.e. movable roof (3b)
The 7 points at the rear end are the upper end χ of the free end of the fixed roof (1)
It is located above the dot so that there is no problem when opening and closing.

The movable roof (3a) at the front end is the movable roof (3b) at the middle part.
Therefore, the gap H generated between the tip of the movable roof (3a) and the fixed roof fil (1) is formed in a folded cross section so that the movable roof (3a) The gap H portion of fll (3a) can be used as a stadium ventilation port or a smoke exhaust port.

Each of the movable roofs (3a) (3b) (3c) has a steel truss structure structure (6) with a finishing material (7) made of a metal material or a membrane material layered thereon, and the rails (5a) (5b).
) (5c) A wheel (8) and its drive device (9) are mounted to run on it.

(Refer to Section 6V) Conventionally, in this type of retractable roof structure, the track section of each movable roof is opened and closed at the same level, so the lower part of the movable roof is at the same height regardless of the purpose of use of the internal space. A structure is required, and when the roof is open, this lower structure obstructs visibility and reduces the sky factor, but in the above embodiment, each movable layer m (3a) (3b) (3c
) By changing the levels of the guide rails (5a), (5b), and (5c), it is possible to ensure a greater sky coverage when the roof is open.

7 to 1O show the storage order of the movable roof,
From the roof closed state shown in Fig. 7, move the movable roof (3a) to the fixed roof (1) side so as to cover the roof (1) (see Fig. 8), then move the movable roof (3b) to the fixed roof (1) side. Fix the roof (
1) Move to the same roof (1) and the moving roof (3b)
(see Figure 9) and then the movable roof (3c
) is moved to the fixed roof (21) side and covers the same roof (2) (see Fig. 10), thus storing the movable roof group on both sides.

Note that each of the movable layers FF1 (3a) (3b) (3cl
The roof can be opened and closed by moving the l at the same time.
It is also possible to make the entire stadium open by making it movable.

Furthermore, as shown in FIGS. 12 to 15, the movable roofs (3a), (3b, and 3c) may be stored on the fixed roof (1) side, or as shown in FIGS. 16 to 18. To,
It may be stored on the fixed roof (2) side.

Furthermore, by increasing the number of movable roofs as shown in FIGS. 19 to 22, it is possible to construct a lower structure (4) that is more suitable for the shape of the stand.

In the illustrated embodiment, the movable roof is (3a) (3b)
Consists of (3c) (3d) (3e) (3f),
Guide rails (5a) (5b) (5c) (5d) (5e) for each movable roof on the stepped lower structure (4)
(5f) has been installed.

In the figure, (4A) is the upper stand, and (4B) is the lower stand.

Figure 23 is a comparison diagram of the spatial volumes of the retractable membrane root structure according to the present invention and the conventional retractable roof structure (P) that moves in parallel along a linear trajectory. According to the embodiment, the spatial volume can be minimized.

Especially in the case of baseball stadiums, although the height of the ball's trajectory gradually decreases toward the outfield stands, in the case of the conventional structure,
The stadium was designed so that the height of the roof would be highest in the center of the stadium, resulting in a lot of wasted space, but this embodiment can solve these problems.

(Effects of the Invention) According to the retractable membrane roof structure according to the present invention, as described above, the curved movable roof arranged between the opposing curved fixed roofs is divided into a plurality of different steps. At the same time, since each of the movable roofs was movably supported on guide rails laid on a step formed on the roof circumference of the lower structure, the guide rail position of each of the movable roofs was adjusted to the height according to the stand shape. By changing the above, it is possible to secure a large sky ratio, and the lower structure that supports each guide rail can be lowered, which together with the ability to minimize the space volume, contributes to economic efficiency. It is true.

Further, according to the present invention, it is possible to accommodate various site shapes by changing the opening/closing direction of the movable roof, and when a larger space is required, it can be accommodated by changing the shape of the movable roof.

Furthermore, it is possible to construct a lower structure that conforms to the shape of the stand.
