FIG. 3 is an enlarged cross-sectional view corresponding to the line AA, and FIG. 3 is a perspective view of a main part of the cable attachment device.

That is, the large space facility shown in FIG. 1 is used as an artificial ski resort 10, and outer walls 12, 12 that are continuous in the direction perpendicular to the plane of the drawing in the figure are constructed on both sides, and the upper ends of these outer walls 12, 12 A membrane roof 14 as a membrane structure is stretched between the parts. The floor surface 18 of the large space portion 16 formed by the outer walls 12 and 12 and the membrane roof 14 is continuously inclined in the extending direction of the outer walls 12 and 12, and the inclined floor surface 18 is Artificial snow is piled up to form a slope, and it is possible to slide on the snow.

The membrane roof 14 shows a state in which air is injected into the large space portion 16 to inflate in a solid line state in FIG. 1, and an internal air pressure is removed in a two-dot chain line state to deflate. The state is shown. The membrane roof 14 is supported by a plurality of cables 20 (see FIG. 2) installed between the upper ends of the outer walls 12, 12. Both ends of the cable 20 are vertically rotatably connected to the outer walls 12 and 12 via anchor metal fittings 22 to smoothly move the membrane roof 14 when inflated and deflated. A machine room 24 and a lift room 26 are provided outside the outer walls 12, 12, and an air conditioner, an artificial snowmaking machine, a snow gun, etc. are installed in the machine room 24.

The membrane body 30 constituting the membrane roof 14 is constructed as a whole by connecting a plurality of membrane pieces 30 a to each other via a connecting member 32 as shown in FIG. As shown in the figure, the connecting member 32 is arranged inside the film body 30 along the connecting end portions of the film pieces 30a, 30a to be connected to each other (note that the large space 16 is defined in the inner and outer directions). The inner presser plate 34 is arranged in the direction of the center, and the same applies to the following), and a pair of outer parts that are located at both ends of the inner presser plate 34 in the width direction and are arranged outside the film body 30. The pressing plate 36, 36 is provided.

The inner presser plate 34 and the outer presser plates 36, 36 are made of stainless steel or aluminum alloy in the form of strips each having a predetermined length. A plurality of them are arranged in a staggered manner. Then, between the inner side pressing plate 34 and the outer side pressing plates 36, 36, the connecting ends of the membrane pieces 30a, 30a are wound around the cord bodies 41, 41 via the cushioning members 38, 40 and sandwiched. , Bolts 42 and nuts 44 are used for tightening and fixing. A hanging plate 46 for attaching a secondary cable (not shown) is vertically provided at a lower end portion of the inner pressing plate 34 at an appropriate interval.

In this embodiment, as shown in FIG. 2, the base plate 50 is fixed via the bolts 40 and the nuts 42, straddling the outer pressing plates 36, 36. A cable attachment device 52 is attached to the base plate 50. The attachment device 52 includes a pedestal 54 attached to the film body 30 and a cover 56 attached to the pedestal 54 so as to be openable and closable.

The pedestal 54 includes a leg portion 62 fixed to the base plate 50 via a bolt 58 and a nut 60, and a recessed seat surface 64 into which the lower side of the cable 20 is fitted. The portion 62 and the seat surface 64 are formed as a continuous U-shaped double structure.

On the other hand, the cover 56 is arranged between the upper ends of the pedestals 54 and closely covers the upper side of the cable 20 fitted to the seat surface 64. The cover 56 is rotatably attached to the pedestal 54 via a hinge 66 provided at one end (left side in the drawing), and a locking mechanism 68 provided at the other end (right side in the drawing). And is detachably locked to the base 54.

The locking mechanism 68 is formed at the tip of the operating portion 70 integrally extending from the other end of the cover 56 along the outside of the pedestal 54, and is attached to the pedestal 54. A locking claw 74 that locks in the formed locking hole 72, and a fixing metal fitting 76 that movably fits around the operating portion 70 and the pedestal 54 are configured. Further, the fixing metal fitting 76 is formed in a channel shape by opening the outer side, while the upper end portions of the operating portion 70 are notched so that the releasing portion 76a of the fixing metal fitting 76 can pass through the notch 78. It has become. Further, a protrusion 80 for preventing the fixing metal fitting 76 from falling is formed at the lower end of the operation portion 70.

In the cable mounting structure for the roof membrane 14 of the present embodiment having the above-described configuration, the base plate 50 is provided outside the connecting member 32 that connects the plurality of membrane pieces 30 a, 30 a that constitute the membrane body 30. Since the cable attachment device 52 is provided via the cable attachment device 52, when the membrane roof 14 is inflated, the cable 20 can be pushed up via the cable attachment device 52 as the membrane roof 14 rises. When the membrane roof 14 is completely inflated, the cable 20 restricts the rise of the roof membrane 14 from the outside of the membrane body 30, and the cable 20 supports the membrane roof 14 in this state.

By the way, in the present embodiment, when the cable 20 is attached to the cable attaching device 52, the engagement mechanism 68 provided at the other end of the cover 56 is released, and the hinge 66 at one end is centered. The cover 56 is left open and the cable 20 is attached in this state. To release the locking of the locking mechanism 68, the fixing metal fitting 76 is moved upward (in the direction of the arrow X in FIG. 2) and the releasing portion 76a of the fixing metal fitting 76 is positioned in the notch portion 78. This is performed by removing the pawl 74 from the locking hole 72.

After fitting the cable 20 to the seat surface 64 of the pedestal 54 with the cover 56 opened, the cover 56 is closed and the locking mechanism 68 is locked, whereby the cable 20 is fixed. It can be fixed to the pedestal 54. Contrary to the above-described unlocking operation, the locking mechanism 68 is locked by allowing the fixing metal fitting 76 to pass through the notch hole 78 and then the locking claw 74 to be engaged with the locking hole 72. This is performed by moving the fixing metal fitting 76 downward (direction of arrow Y in the figure). By moving the fixing fitting 76 downward in this manner, the fixing fitting 76 reliably prevents the operating portion 70 from being separated from the pedestal 54, and prevents the locking mechanism 68 from being released.

Therefore, by fixing the cable 20 to the pedestal 54 in this way, the cable 20 is attached to the connecting member 32 and further to the film body 30 via the base plate 50 to which the leg portions 62 are attached. It will be.

Although the cable attachment device 52 is fixed to the film body 30 via the connection member 32 in the present embodiment, the cable attachment device 52 may be directly attached to the film body 30. Further, although the present embodiment discloses the case where the present invention is applied to the membrane roof 14 of the artificial ski resort 10, the present invention is not limited to this, and the present invention is applied to other large space facilities using a membrane roof, for example, a general dome. It goes without saying that the cable attachment device for the membrane structure of the invention can be applied.
