Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to air membrane roof structures for competition facilities, event facilities, and the like.

(Prior art) Conventionally, a hollow hemispherical dome body used in large, all-weather multipurpose stadiums, etc. is provided with a band-shaped opening along an imaginary plane that divides the body into two in the radial direction. A dome with a lid that allows for sunlight and ventilation as needed was published in Japanese Patent Laid-Open No. 59-126835.
It is proposed in the publication No.

(Problems to be Solved by the Invention) In the conventional dome described above, the shape of the roof and the indoor space are constant, and it is not possible to achieve different effects depending on the use.

The present invention was proposed in view of the problems of the prior art, and its purpose is to provide an air membrane that enables a variety of effects on roofs and indoor spaces, and that can be constructed on existing facilities. The point is to provide a roof structure.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the air membrane roof structure according to the present invention has a roof structure that is suspended between pillars erected outside a facility via steel wires from each pillar. A cable-stayed beam is installed, and a plurality of cylindrical air membranes are successively spanned between both sides of the cable-stayed beam and the facility perimeter beam.

In the air membrane roof structure, self-propelled devices fixedly installed at both ends of the cylindrical air membrane are installed on guide rails installed on both sides of the cable-stayed beam and on opposing surfaces of the cable-stayed beam in the facility perimeter beam, respectively. It is recommended that the roof be mounted so that the roof can be opened and closed smoothly.

Furthermore, movable terminals attached to both ends of wires attached to the joint valleys of adjacent cylindrical air IIIs are movably mounted on each of the guide rails of the cable-stayed beams and the facility surrounding beams, so as to prevent strong winds. This is to strengthen the air membrane roof during times of stress.

(Function) According to the present invention, as described above, columns are erected outside the facility, and cable-stayed beams are suspended between the columns via steel wires, and the cable-stayed beams are thus arranged between the columns. A plurality of cylindrical air membranes are successively spanned between both sides of the cable-stayed beam and peripheral beams placed around the facility, and each cylindrical air membrane covers the air membrane roof of the facility. Since the above-mentioned cable-stayed beam is configured as a horizontal straight beam,
By constructing diagonal straight beams, arch beams, etc., the roof surface and interior space are shaped to suit the purpose.

In the invention of claim 2, a self-propelled device is fixedly installed at both ends of each cylindrical air membrane, and each self-propelled device is opposed to both sides of the cable-stayed beam and the cable-stayed beam in the facility peripheral beam. By mounting it on guide rails installed on the respective surfaces, the air IIa roof can be opened and closed by moving each of the cylindrical air films using the guide rails as a guide.

In the invention of claim 3, wires are attached to the joint valleys of the adjacent cylindrical air membranes, and both ends of the wires are mounted so as to be freely movable on guide rails installed on the cable-stayed beams and the facility peripheral beams. A movable terminal is attached to the movable terminal, and the wire resists wind pressure during strong winds, and the wire moves along the guide rails via the movable terminal when the air membrane roof is opened and closed. This prevents any hindrance to the opening/closing operation of the air membrane roof.

(Example) Hereinafter, an illustrated example in which the present invention is applied to an air membrane roof structure of a baseball stadium will be described.

(1) are a pair of opposing poles that are erected on the outside of the stadium; one is erected outside the outer wall behind the back net, and the other is erected outside the outer wall behind the back screen.

A cable-stayed beam (2) is installed between the above-mentioned twin columns (]) (11, and the cable-stayed beam (2) is tensioned from the top of each of the above-mentioned columns (1) by a steel wire (3) and lifted. (See Figures 1 to 3) In the figure, (4) is the restraining rope.

Furthermore, a peripheral beam (6) is provided at the upper end of the outer wall (5) over the entire length of the outer circumference of the stadium.

Furthermore, both sides of the cable-stayed beam (2) and the peripheral beam (6)
), guide rails (7) and (8) are installed on the surfaces facing the cable-stayed beam (2), respectively.

Both sides of the cable-stayed beam (2) and the peripheral beam (
A plurality of cylindrical air membranes (9) are arranged in succession between 6) and (6), and self-propelled devices (10) are installed at both ends of each cylindrical air membrane (9). The self-propelled devices (10) are fixedly mounted on the guide rails (7) and (8) of the cable-stayed beam (2) and the peripheral beam (6).

The self-propelled device (10) is a self-propelled device and a central ventilation control room (
an electric drive device that operates upon receiving a command from the guide rail (7) (
8) It consists of a running wheel or a slider that runs on the top.

Furthermore, a wire (
12), and movable terminals (13) mounted on the guide rails (7) and (8) so as to be movable are attached to both ends of the wire (12).

The movable terminal (13) is attached to the guide rail (7).
) (equipped with wheels or sliders that run on 81.

Since the illustrated embodiment is configured as described above, the cylindrical air membrane (9) is connected to the self-propelled device and the air blowing central control room (11).
) is activated by a self-propelled device (lO) that operates in response to a signal from the cable-stayed beam ( 2
) to the left in both directions to open the roof surface as shown in Figure 2.

Also, the cylindrical air Ill! (9) is a cable-stayed beam (2) from the open roof state shown in FIG. By moving to the center side of
The roof surface is closed as shown in FIG.

Each of the cylindrical air membranes (9) must maintain its longest span so as not to sag when the roof surface is opened.

Therefore, the self-propelled devices (lO) at both ends of the cylindrical air membrane (9) running on the respective guide rails (7) and (8) of the cable-stayed beam (2) and the peripheral beam (6) move at different speeds. do,

The speed control of the self-propelled device (lO) and the air blowing to the cylindrical air membrane (9) are carried out collectively by the self-propelled device and the air blowing central control room (11).

Thus, the wire (12) attached to the joint valley where adjacent cylindrical air membranes (9) are connected has movable terminals (13) at both ends of the wire (12) connected to the cable-stayed beam (2) and the surrounding area. Because it is mounted on each guide rail (7) (8) of the beam (6), it is protected against strong winds.

When the air film is opened and closed, the movable terminals (13) at both ends of the wire (12) use the guide rails (7) and (8) as guides to act as a reinforcing material against wind pressure. It moves following the membrane (9).

Also, the cable-stayed beam (2) installed between the above-mentioned - twin pillars (+)
