Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a retractable roof structure, and more particularly to a retractable roof structure that can be partially opened and closed depending on the weather.

(Prior Art and Problems) As is well known, structures used for athletic events such as baseball stadiums and track and field stadiums do not have roofs attached to them.

This is intended to allow athletic competitions to be held in as natural a environment as possible, but if it rains or it rains during a competition, the competition must be suspended or canceled.

Therefore, all-weather stadiums have recently been proposed, such as one ton of air! JM construction is attracting attention.

However, the air membrane structure has the following problems.

In other words, the air membrane 14m has a roof made of a membrane material made of synthetic resin, etc., and seals pressurized air that is slightly higher than atmospheric pressure inside, but with this structure, the pressurized air is not released outside. In order to prevent leakage, the structure of the entrance/exit 4'I becomes complicated.

Furthermore, not only will lighting and ventilation inside the stadium become difficult, but the purpose of holding or watching competitions in a natural environment will be diminished.

This invention was made in view of the above-mentioned conventional problems, and allows the roof to be partially opened and closed depending on the weather, allowing natural lighting and ventilation during sunny days, allowing athletic events to be held in a natural environment. To provide a retractable roof which can be opened and closed even in rainy weather and can be opened and closed easily.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a fixed roof having a circular opening at the center and having a peripheral edge fixed to an outer wall, and a fixed roof constructed radially from the center of the circular opening. a girder, a guide rail laid on a fixed roof from the intersection of the girder, the girder, and the opening in parallel with another girder adjacent to the girder, and a plurality of almost identical fan-shaped movable rails that divide the opening by the girder. It is characterized by comprising a roof, rollers that roll along the guide rails attached to the tip and fan-shaped outer end of each movable roof, and a moving device for the movable roof.

(Embodiments and Effects) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 show an embodiment of a retractable roof according to the present invention.

The retractable roof shown in the figure has a concentric opening 10 in the center.
It is generally composed of a ring-shaped fixed roof 12 fixed to a cylindrical outer wall with an upright peripheral edge, and eight movable roofs 14a to 14h that open and close the opening 10.

The above 1; if D 10 is defined by a ring beam 15 fixedly installed on the inner peripheral edge of the fixed roof 12, and eight large beams 16 are formed so as to divide the circumference from the center at equal angular intervals.
．． 16... are installed radially, and 59 annular beams 18 are installed in the center.

The radius of the opening 10 is set to be approximately the same as the width W of the fixed roof 12, and the girder 16 extends from the annular beam 18 to the fixed roof 1.
2 to its outer edge.

On each girder 16, as shown in FIGS. 2 and 3,
A first guide rail 20a consisting of upper and lower guide rails 201 and 202 in which H-shaped steel materials 2 are stacked in steps.
has been installed.

Further, on the fixed roof 12, from the intersection of each large beam 16 and the opening 10, a small guide rail 22 having the same structure as the first guide rail 20a is arranged so as to be parallel to other large beams adjacent in the circumferential direction. A second guide rail 20b is laid, and a small beam 22 is constructed parallel to the first and second guide rails 20a and 20b from the midpoint of the length installed in the opening 10 of each large beam 16, A third guide rail 20c having the same configuration as the first and second guide rails 20a and 20b is provided on its upper surface.

The movable roofs 14a to 14h have the opening 10 connected to the main beam 1.
It has a planar shape that is almost the same as a fan shape divided into 6 and 8 parts, and both sides are bent diagonally upward, and each movable roof 14a to 1
When opening 1o is closed with 4b, between adjacent movable roofs,
The sides overlap each other to prevent rainwater from entering the structure, and the lower surface of each movable roof 14a to 14b has a tip, a midpoint of the side, both ends of the arcuate side, and an arc. At the midpoint of each side, the first . Second. The rollers 24 rolling along the third guide rails 20a, b, Q are 6
They are attached at different locations and move in parallel in the direction of the arrow as shown in Figure 2 (A).

FIG. 3 shows an example of the engagement between the roller 24 and the guide rails 20a to 20c.

In this example, the rollers 24 are connected to each guide rail 208-2.
A pair of upper and lower rollers 24 are arranged to sandwich the flanges of the upper guide rail 201 from both sides.
The F roller 24a is composed of four rollers 1 and 24b, and one end of the F roller 24a is fixed to the frame 26 of the movable roofs 148 to 1411.
It is rotatably supported by a spindle 30 on a box-shaped frame 28 whose lower end is open, and the lower opening 524b is rotatably supported by a spindle 34.34 on a pair of plates 32.32 supported by a spindle 3o. supported.

and first and third guide rails 20a.

The frame 28 provided along the axis 20c is connected to the connecting shaft 36.
and is connected to phase B via a joint 38.

Note that the member 4o shown in FIG. 3(B) is a pin that connects the pair of plates 32, 32.

On the other hand, a rotating sheave 42 is pivotally supported at appropriate locations on the web of the lower guide rail 202 of each guide rail 208 to 20c, a wire 44 is wound around the rotating sheave 42, and one end of the wire 44 is connected to each turn lamp. It is secured to the roofs 14 to 14h, and the other end is rolled up by a winding drum of a winch (not shown).

In the retractable roof constructed as described above, as shown in FIG. 44 in a predetermined direction with a winch, the rollers 24 roll along the guide rails 20a to 200, and each movable roof 14a to 14h moves in parallel toward the center, closing the opening 10. On the other hand, if the winch is reversed, the opening 10 can be opened in the opposite direction.

This open/closed state is detected by, for example, providing a limit switch or the like that is activated when the movable roofs 14a to 14h come into contact with the annular beam 18, and the winding by the winch is controlled.

During the opening/closing of each of the movable roofs 14a to 14h, each of the movable roofs 14a to 171h moves while being supported at five points by the [1-ra-24], so it can be easily moved in a stable state.

Note that the small beam 22 of the above embodiment and the third guide rail 20c laid on the upper surface thereof are not necessarily required, but the first and second guide rails 20a.

20b and four or three rollers 24 may support each of the movable roofs 14a to 1/Ih.

(Effects of the Invention) As explained in detail in the examples, in the retractable roof according to the present invention, by moving the movable roof toward the center and closing the opening, the inside of the structure can be closed. It can block rainwater from entering and sunlight, making it possible to hold athletic events and events even in the rain or under the scorching sun.

On the other hand, during the middle of the season or when the weather is sunny, the movable roof is moved to the fixed roof, leaving the openings open, making it possible to hold athletic events under the sky.

In addition, if the opening is covered with a movable roof at night, the lighting inside will be reflected, increasing the lighting effect.
