Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an open / close dome roof structure having a large opening area when the roof is opened.
[0002]
[Prior art]
In a large openable dome roof structure, generally, a movable roof that opens a part of the fixed roof and swirls in a fan shape is arranged on the upper part of the outer wall with the seats inside. When the weather is good, the movable roof is swiveled or slid to open a part of the roof to the outdoors, and at the same time, the outside air is positively taken into the room at the same time. However, in this type of roof structure, the area of the fixed roof that supports the movable roof is large, and the opening position thereof is only a specific position, and each part cannot be evenly opened.
[0003]
On the other hand, for example, in the roof opening and closing type dome shown in Japanese Patent Publication No. 3-26747, the movable roof has a structure that can be opened and closed like a diaphragm shutter of the camera from the roof center. It becomes an open shape even in the shape of a windmill.
[0004]
[Problems to be solved by the invention]
However, in the above structure, since one movable roof is made to correspond to each fixed roof, in order to support each movable roof safely and stably, the area occupied by the fixed roof is inevitably wide. It was necessary to take, and the open area when the roof was opened could not be taken sufficiently large.
[0005]
Accordingly, the present invention solves the above-mentioned problems, and its purpose is basically to adopt a camera aperture shutter-shaped opening / closing method so that the opening area when fully open can be increased compared to the conventional case. An openable dome roof structure is provided.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 of the present invention includes an outer wall body having a substantially circular planar shape , a plurality of outer wall bodies arranged on the outer wall body along the circumferential direction, and Fan-shaped fixed roofs each disposed toward the center of the roof, which is the center of the circle of the outer wall body , and a guide that is provided along the edge of the fixed roof and that can extend and contract toward the roof center; A movable roof that is stacked on the top of each fixed roof and is movable in the shape of a diaphragm shutter of a camera toward the center of the roof , and has an edge supported by the guide when moving; The roof is divided into a plurality of pieces and is configured to be able to be overlapped with each other. While the guides are extended and joined to each other at the top of the roof center, the movable roof is supported by the guides. Close the roof Characterized in that it moves in a direction toward and opening.
[0007]
According to the openable dome roof structure of the present invention, a movable roof is placed on each roof in good weather and the like, and the movable roof is extended toward the center of the roof according to the weather, time zone, and the like. As a result, each movable roof has a shape similar to the aperture shutter of the camera and is fully closed. The roof is fully opened by performing the reverse operation from this state. In the fully opened state, each movable roof is divided and can be overlapped, so that an open area when opened can be widened. Furthermore, since each guide is stretched and joined to each other at the top of the roof center, the movable roof is supported by each guide and moves in the direction of closing and opening the roof. Stability and safety can be increased .
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0010]
1 and 2 show a movable dome roof structure according to the present invention, and the structure in the figure is an example of a case where it is applied to a soccer field or the like, and is constructed by connecting a circular plane shape. A plurality of spectator seat stands 2 are arranged in an approximately oval shape inside a large number of inner and outer pillars constructed between the five outer wall bodies 1 and the outer wall body 1, and an inner bottom surface surrounded by a mortar shape in the spectator seat stand 2 Is the soccer competition scene 3.
[0011]
Further, five fixed roofs 4 that rise at a predetermined slope toward the roof center that is the center of the circle connecting the upper portions of the respective wall bodies 1 are fixedly arranged. The covering intermediate movable roof 5 is laid out so as to be movable toward the center of the roof, and the upper movable roof 6 is also laid out on the intermediate movable roof 5 so as to be movable toward the center of the roof. .
[0012]
A fixed guide 7 is provided along the circular arc surface at the edge of each fixed roof 4, and the edge of the intermediate movable roof 5 is supported inside the fixed guide 7 and along the inside of the fixed guide 7. An intermediate movable guide 8 that telescopically expands and contracts is arranged. Further, the upper movable roof 6 is supported inside the intermediate movable guide 8 and can be telescopically expanded along the inner movable guide 8. A guide 9 is arranged.
[0013]
As shown in detail in FIG. 5, each of the guides 7, 8, and 9 is formed of a steel frame structure having a substantially U-shaped cross section and slidably engaged with each other. As shown in the figure, when the lengths are L1, L2, and L3, the movable roofs 5 and 6 at the time of extension are secured by securing a sufficient length for the overlapping dimensions T1 and T2 at the time of maximum extension. In addition to being able to be held in a stable and safe state, although not shown in the drawings, the upper movable roofs 6 are joined to each other in a closed state like a diaphragm shutter, thereby forming a one-piece roof, and stability or A mechanism for improving safety is employed.
[0014]
3 (a) to 3 (c) show the form of the above structure from fully closed to fully open. In (a), all the movable roofs 5 and 6 are closed in the form of a diaphragm shutter, thereby the structure. The interior is completely enclosed and can be used in all weather conditions. The telescopic guides 7, 8, and 9 are in an extended state, but are not shown in the figure.
[0015]
FIG. 5B shows a state in which only the upper movable roof 6 is lowered along the guide and overlapped with the lower portion of the intermediate movable roof 5, thereby obtaining an opening area in the intermediate state. In (c), the upper movable roof 6 and the intermediate movable roof 5 are further lowered from this state and overlapped with the lower portion of the fixed roof 4. In the case of (b) or (c), it is used to block the western sun and allow the game to be played in the best condition.
[0016]
FIG. 4D shows a state in which the movable roofs 5 and 6 are fully opened, whereby the competition upper surface 3 and most of the audience seats are opened to the outside. Note that the guides 7, 8, and 9 are degenerated in a state where the movable roofs 5 and 6 are opened.
[0017]
As described above, when the movable roofs 5 and 6 are opened, the telescopic guides 7, 8, and 9 are first extended, and the movable roofs 5 and 6 are guided by these, so that the opening operation is stable and safe. The nature is also increased. On the other hand, when the movable roofs 5 and 6 are closed from the fully opened state of FIG. 3D, the guides 7, 8, and 9 are first extended and joined to each other at the top, and then sequentially movable along the guides. Raise the roofs 5 and 6. Therefore, at the time of closing, the guide remains to the end.
[0018]
FIG. 4 shows the form of the entire structure in its fully open state, and the five roofs 4 (including 5 and 6) are continuously formed on the outer wall 1 as a wall-like structure that rises with a predetermined gradient. It will have a new appearance.
[0019]
【The invention's effect】
As apparent from the above description, according to the openable dome roof structure of the present invention, the movable roof is divided and can be overlapped, so that there is an advantage that the opening area when opened can be widened. Also, since each guide is extended and joined to each other at the top of the center of the roof, the movable roof is supported by each guide and moves in the direction of closing and opening the roof. Stability and safety can be increased.
