DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mounting a roof membrane in which a roof membrane is supported by a cable installed between outer walls.

[0002]

2. Description of the Related Art In recent years, there has appeared a structure in which a roof of a large space facility having a pillarless structure such as a dome is constructed as a membrane roof. In this membrane roof structure, the upper end of the outer wall surrounding the large space facility is covered with a roof membrane formed of a waterproof flexible membrane. The roof membrane is inflated (expanded) by injecting air into the inside of the facility, and a dome-shaped roof having a central portion swelled in the inflated state is formed.
In order to prevent the roof membrane from being fluttered by the influence of wind or the like, the roof membrane is usually supported by a cable installed between opposed outer walls.

[0003]

However, in such a conventional membrane roof structure, since the entire large space facility must be continuously covered with the roof membrane, the roof membrane has an extremely large area. It will be. For this reason, when the roof membrane is manufactured in a factory at the time of construction of the large space facility, and the roof membrane is to be carried to the site, even when the roof membrane is folded, it becomes extremely bulky, and the transportation becomes difficult. In particular, when the insulation film is attached to the roof film to form an insulation film roof, or when a cable is previously attached to the roof film in a factory, the roof film will be further bulky,
Its transportation becomes extremely difficult.

Therefore, it is conceivable that the roof membrane is composed of a plurality of membrane pieces and these membrane pieces are assembled on site. In this case, even if a heat insulating material is attached to each membrane piece, Since the connecting fitting is provided at the connecting portion of the membrane piece, the heat insulating material cannot be provided at the attaching portion of the connecting fitting. Therefore, there is a problem that the outside air temperature is greatly affected by the inside of the facility from the connecting portion of the membrane piece, and as a result, the air conditioning facility for keeping the temperature in the large space facility constant becomes large. Therefore, in view of such conventional problems, the present invention configures the roof membrane by connecting a plurality of membrane pieces to facilitate transportation thereof, and at the same time, the outside temperature affects the facility through the connecting portions of the membrane pieces. It is an object of the present invention to provide a method for attaching a roof membrane that can significantly reduce the noise.

[0005]

In order to achieve the above object, a first method for attaching a roof membrane according to the present invention is a roof stretched between the outer walls facing each other in a large space facility so as to be inflatable and deflatable. In a method of attaching a roof membrane, which comprises a membrane, and the roof membrane is supported via a cable laid between these outer walls, a heat insulating material is attached to a plurality of membrane pieces constituting the roof membrane, and at the same time, each of the membrane pieces A joint membrane was extended in a branched state inside the end on the connection side, each membrane piece to which this joint membrane was attached was laid on the floor surface of a large space facility, and a connecting metal fitting was attached between these membrane pieces. The cable is routed, the connection side end of each membrane piece is fixed to this connecting fitting via a seal member, and then the cable is attached to a predetermined position on the outer wall, and air is injected into the facility in this state. Bulge the roof membrane, this It said joint layer comrades are next set in out state connected to each other, and a method of covering the connecting fitting in the connected joint film.

In order to achieve such an object, the second method of attaching the roof membrane according to the present invention is such that the outer membrane and the inner membrane are stretched between the outer walls facing each other in a large space facility so that they can be inflated and deflated. In the method for attaching a roof membrane, which comprises a roof membrane configured as a double membrane structure by means of a cable installed between the outer walls, heat insulation is applied to a plurality of membrane pieces constituting the inner membrane. While attaching the material, the joint membrane is extended in a branched state inside the connection side end of each of these membrane pieces, and each membrane piece to which this joint membrane is attached is laid on the floor surface of the large space facility, and this Laying a plurality of membrane pieces constituting the adventitia on the outer side of the inner membrane, laying the cable with connecting fittings attached between the membrane pieces of the inner membrane and the adventitia, and connecting side end of each membrane piece Part is fixed to this connecting metal fitting through a seal member. After that, the cable is attached to the outer wall at a predetermined position, air is injected into the facility in this state to swell the roof membrane, and in this bulge state, the joint membranes adjacent to each other are connected to each other, and this connection is made. The inner side of the connecting fitting is covered with the joint film.

Further, in the first or second attachment method, it is desirable to attach a heat insulating material to the joint membrane.

[0008]

According to the first method of attaching the roof membrane of the present invention having the above-described structure, the joint membrane is extended in a branched state inside the connection side end of each membrane piece to which the heat insulating material is attached. By laying each membrane piece to which a joint membrane is attached on the floor of a large space facility and connecting each piece through a connecting metal fitting, the roof membrane can be assembled on site.

The connecting fitting is attached to a cable, and the roof membrane is bulged by injecting air into the facility with the cable attached to a predetermined position on the outer wall. Therefore, the roof membrane is thus bulged so that the roof membrane is floated from the floor surface, and the joint membrane extending in a branched state inside the connection-side end of the membrane piece is hung downward. In this way, the roof membrane floats up and the joint membrane hangs down, which simplifies the connection between adjacent joint membranes.
The inside of the connecting fitting can be covered by the connection of these joint membranes. That is, by covering the connecting fittings with the joint membrane in this way, the outside air temperature affecting the facility can be blocked by the joint membrane through the joint portions of the membrane pieces, and the heat insulation efficiency of the roof membrane can be improved.

According to the second method for attaching the roof membrane of the present invention, the roof membrane is constructed as a double membrane structure by the outer membrane and the inner membrane, and the outer membrane and the inner membrane are constituted. By laying each membrane piece on the floor and connecting the respective connection side end portions through the connecting metal fittings, the roof membrane can be assembled on site. Even when the roof membrane has a double membrane structure, the roof membrane should be swollen when connecting the joint membrane extending inside the connection side end of the membrane piece of the inner membrane. This makes it possible to easily connect the joint membrane. Therefore, according to the second mounting method, it is of course possible to improve the heat insulation efficiency of the roof membrane by covering the coupling fitting with the joint membrane, and the roof membrane has the double membrane structure, so that the roof membrane is The overall heat insulation efficiency can be further improved.

Further, in the first or second attachment method, by attaching a heat insulating material to the joint membrane, the heat insulating efficiency of the connecting portion of the membrane piece can be remarkably improved.

The same applies hereinafter). To be Also. Inside the connection-side end of each membrane piece 36, the joint membrane 48 is appropriately spaced from the tip of the end of the membrane piece 36.
And the joint films 48 are extended from the film piece 36 in a branched state. A heat insulating material 50 is attached to each outer surface of the joint membrane 48.
An air introduction hole 52 is formed in the membrane piece 36 at a position closer to the end side than the welded portion of the joint membrane 48.

By the way, when the roof membrane 14 is attached to the artificial ski resort 10, each of the membrane pieces 34 and 36 and the cable 20 are carried into the artificial ski resort 10 as shown in FIG.
The roof membrane 14 is assembled through the work steps shown in (A) to (D). Note that FIG. 2 is shown as a cross section in a direction corresponding to the line AA in FIG.

That is, in order to attach the roof membrane 14, first, as shown in FIG. 2A, each membrane piece 36 of the inner membrane 32 to which the joint membrane 48 is attached is attached to the floor surface 1 of the artificial ski resort 10.

The roof membrane 14 is constructed by connecting the outer membrane 30 and the inner membrane 32 to each other by connecting the membrane pieces 34 and 36 via the connecting metal fittings 38.
And since the cable 20 is assembled at the artificial ski resort 10 on site, it can be made significantly easier to carry.

By the way, the heat insulating material 46 is attached to the membrane piece 36 of the inner membrane 32. Since the membrane piece 36 is connected to the membrane piece 34 of the outer membrane 30 to each other through the coupling metal fitting 38, this coupling metal fitting is used. The heat insulating material 46 is cut off at the mounting portion of 38, and the outside air temperature is easily affected through the connecting metal fitting 38 portion. Here, in the present embodiment, since the inner side of the coupling fitting 38 is covered with the joint membrane 48 extending in a branched state from the membrane piece 36, the joint membrane 48 exerts a heat insulating effect, so that It is possible to block the outside air temperature that affects the large space portion 16. Further, at this time, since the heat insulating material 50 is attached to the joint film 48, the heat insulating effect in the connecting metal fitting 38 portion can be remarkably improved.

Therefore, in this embodiment, since the heat insulation effect of the roof membrane 14 is improved, the heat retaining effect inside the artificial ski resort 10 is significantly improved, and the air conditioner installed in the artificial ski resort 10 is downsized. Also, the energy consumption for air conditioning can be reduced.

Further, in this embodiment, when the joint membrane 48 is connected, the roof membrane 14 is bulged and the roof membrane 14 is floated from the floor surface 18.
This connecting work can be easily performed from the inside of 4.

Although the roof membrane 14 of the present embodiment has a double membrane structure composed of the outer membrane 30 and the inner membrane 32,
The present invention can be applied not only to this double film but also to a roof film having a single film structure.
It is needless to say that the heat insulating structure of the roof membrane of the present invention can be applied to other large space facilities using a roof membrane, such as a general dome.
