Embodiments of the present invention will now be described with reference to the drawings, but these embodiments are merely examples of the present invention and do not limit the present invention in any way.

(Embodiment 1) FIGS. 1 and 2 show a first embodiment of an air tube opening / closing roof system of the present invention, and FIG. 1 is a diagram showing a side structure of the system. 2 is a perspective view showing one structural unit of the present system.

As shown in the figure, the air tube opening / closing roof system according to the present embodiment supports a plurality of air tubes 1 and the other air tubes 1 adjacent to each other while supporting the longitudinal direction of each air tube 1. Holding cable (holding connecting member) 2 and connecting cable 3 that is vertically connected to a plurality of positions of the holding cable 2 upward.
And a suspension cable 4 that integrally suspends these connecting cables 3, and the suspension cable 4 and the presser cable 2 are formed, for example, in a curtain rail shape in a building to which the system is attached. It is suspended by a sliding member (not shown). In addition, in the said structure, the some connection cable 3 and the suspension cable 4 comprise the vertical support member 5. As shown in FIG.

As shown in FIG. 2, the air tube 1 is, for example, a cylindrical bag having an airtight space.
The fiber is formed by coating a polymer material having low gas permeability such as polyvinylidene chloride and a protective film such as nylon or polyethylene on the surface. A pressurizing / depressurizing pump (not shown) is connected to each of the air tubes 1, and is configured so that air can be sent to the inside to be expanded and the inside can be depressurized to contract. By connecting a large number of the air tubes 1 with the pressing cables 2, the film surface of the open / close roof is formed. Therefore, this film surface is a double film having a film surface facing the outside and a film surface facing the inside. Since the opening / closing roof system of the present invention can have the double film structure as described above, by adopting the system of the present invention, it is possible to avoid dew condensation and sound leakage which are unavoidably generated in the conventional single layer film material. Problems can be easily overcome.

In the above structure, the external force applied to the film surface is transmitted by the suspension cable 4 when the external force is vertically downwardly loaded, as shown in FIG. As shown in b), the pressing cable 2 transmits the force.

Next, the basic operation of the open / close roof system of this embodiment will be described with reference to FIGS. 4 (a) to 4 (c).

FIG. 4 (a) shows when the roof is opened, and the air in each air tube 1 is almost completely evacuated and is housed in one of the roofs together with the cable 3. When closing the roof, see Fig. 4 (b).
As shown in, air is blown in sequentially from the air tube 1 at the tip. When the air tube 1 at the base end is filled with air in this manner, the roof is completely closed as shown in FIG. 4 (c).

FIG. 5, FIG. 6 and FIG. 7 are schematic diagrams in which the opening / closing roof system of this embodiment is applied to an actual indoor exercise facility.
Shown in. FIG. 5 is a floor plan of the facility, in which reference numeral 1 is used.
Reference numeral 0 is an eave roof portion of the facility, and this portion has, for example, a suspension structure. Further, reference numeral 11 is an opening of the roof. FIG. 6 is a cross-sectional view of the same facility in the lateral direction, in which reference numeral 12 is a spectator seat. FIG. 7 is a vertical sectional view of the facility. As shown in these figures,
In the case of a large-diameter roof, it is clear that the facility can be significantly reduced in weight by adopting the air tube type opening / closing roof of the present application. Therefore, by adopting the air tube opening / closing roof of the present invention as the opening / closing roof of the facility, there is an advantage that the structure of the facility itself can be simplified as compared with the structure of the facility using the conventional opening / closing roof. Along with the fact that the occupied volume of the roof can be reduced, there is an advantage that the degree of freedom can be increased by designing the facility.

Further, in the air tube opening / closing roof system of the present invention, it has been described that the problems of dew condensation and sound leakage can be easily solved by the double film structure. Furthermore, by the double film structure, the roof is closed. In the open state, it is difficult to release the positive or negative temperature indoors to the outside,
There is a new advantage that the indoor temperature control can be economically performed. Furthermore, it is possible to actively utilize this double membrane to develop various temperature adjustments. For example, in winter, hot air can be blown into the tube to assist in heating the interior of the room, and snow on the roof surface and dew condensation can be prevented. On the contrary, in the summer, blowing the cool air into the tube can block the hot air from outside and assist the indoor cooling.

Further, in this opening / closing roof system, since the air tube is a basic constituent element, overall,
Locally, it has a very flexible structure. Therefore, even if the ground of the facility is unevenly subsided or the facility is subjected to the phase difference of the seismic force, the generated strain can be easily mitigated. Therefore, the open / close roof system of the present invention can be suitably attached to a facility that must be built on soft ground such as a landfill.

(Embodiment 2) FIGS. 8 and 9 show a second embodiment of the air tube opening / closing roof system of the present invention, and FIG. 8 is a side view of the system. 9 is a perspective view showing one structural unit of the present system, and the same components as those in FIGS. 1 and 2 are designated by the same reference numerals to simplify the description.

As shown in the figure, the air tube opening / closing roof system of this embodiment supports a plurality of air tubes 1 and the other air tubes 1 adjacent to each other while supporting the longitudinal direction of each air tube 1. Holding cable (holding connecting member) 2, a rigid bundle member 30 vertically downwardly connected to a plurality of places of the holding cable 2, and a hanging cable 4 integrally supporting the bundle member 30 from below.
The suspension cable 4 and the pressing cable 2 are supported by a sliding member (not shown) in the form of a curtain rail, for example, which is formed in a building to which the system is attached. In addition, in the said structure, the some bundle material 30 and the suspension cable 4 comprise the vertical support member 50. FIG.

As shown in FIG. 9, the air tube 1 is, for example, a cylindrical bag having an airtight space as in the case of the first embodiment. For example, fibers have low gas permeability such as polyvinylidene chloride. A polymer material is coated, and a protective film such as nylon or polyethylene is formed on the surface of the material. A pressurizing / depressurizing pump (not shown) is connected to each of the air tubes 1, and is configured so that air can be sent to the inside to be expanded and the inside can be depressurized to contract. By connecting a large number of the air tubes 1 with the pressing cables 2, the film surface of the open / close roof is formed. Therefore, this film surface is a double film having a film surface facing the outside and a film surface facing the inside. With this double film structure, as described above, it is possible to easily overcome the problems of dew condensation and sound leakage that are unavoidably generated in the conventional single layer film material.

In the above structure, the external force applied to the film surface is transmitted by the suspension cable 4 when the external force is vertically downwardly loaded, as shown in FIG. As shown in b), the pressing cable 2 transmits the force.

The basic operation of the open / close roof system of this embodiment is the same as the operation described in Embodiment 1 with reference to FIGS.

11 and 12 are schematic diagrams in which the opening / closing roof system of this embodiment is applied to an actual indoor exercise facility. FIG. 11 is a cross-sectional view of the facility in the lateral direction.
[Fig. 3] is a vertical sectional view of the facility. As shown in these figures, in the case of a large-diameter roof, it is apparent that the facility can be significantly reduced in weight by adopting the air tube type opening / closing roof of the present application. Therefore, by adopting the air tube opening / closing roof of the present invention as the opening / closing roof of the facility, there is an advantage that the structure of the facility itself can be simplified as compared with the structure of the facility using the conventional opening / closing roof. Along with the fact that the occupied volume of the roof can be reduced, there is an advantage that the degree of freedom can be increased by designing the facility. These advantages are the same as those obtained in the first embodiment. Besides, it is apparent that the various advantages described in the first embodiment can be similarly obtained in the opening / closing roof system having the configuration of the second embodiment.

In each of the above embodiments, the air tube is described as a cylindrical bag-shaped member as shown in FIGS. 13 (a) and 13 (b), but the air tube used in the present invention has this shape. Not limited to. For example, FIG. 14 (a)
As shown in (b) and FIGS. 15 (a) and (b), by providing the reinforcing tension member 100 inside in the shape of a partition, its width can be freely changed, and the thickness of the roof and the suspension can be changed according to the stress. You can adjust the garter spacing of the cables.
In addition, if the shape of each air tube is tapered so that the diameter gradually decreases from one end to the other end, the overall shape of the open / close roof can be made into a fan shape. It can be operated to close or close. As described above, since there are various variations in the shape of the air tube, by adopting the air tube opening / closing roof system of the present invention, it is possible to construct the opening / closing roof of various shapes.

[0026]

As described above, according to the air tube opening / closing roof system of the present invention, the following effects can be mainly obtained.

1) Since it is more weighing than the conventional roof, the driving unit for opening and closing becomes simple, the influence on the lower structure (main body of the facility) is small, and the cost for constructing the facility can be reduced.

2) Since the injection of air is used as the opening / closing driving force, it can be installed simply and at low cost.

3) Since the double film structure is adopted, the problem of dew condensation peculiar to the film material and the problem of sound leakage can be easily solved.

4) By blowing hot air into the double film, it is possible to prevent snow from melting on the roof surface and prevent dew condensation.

5) When the roof is opened, the double membrane is crushed due to the removal of air inside, so that the space of the facility can be effectively used.

6) Since the structure is soft both locally and locally, it does not have to be affected by the uneven settlement of the construction ground of the facility and the phase difference of the seismic force, and it is constructed on soft ground such as landfill. It is most suitable for the opening and closing roof attached to the facility.
