  In the openable roof structure described in Patent Document 1, a ring-shaped rail is laid along the outer peripheral edge of the movable roof portion, and a traveling device provided on the outer peripheral edge of the movable roof portion passes through the groove of the rail. The movable roof turns by running. However, during snowfall or strong winds, snow and dust may enter the rail grooves, which may hinder the travel of the travel device. For this reason, maintenance work such as snow removal work and cleaning work in the groove of the rail frequently occurs, and the movable roof part cannot be turned at any time.

  This invention is made | formed in view of this point, and it aims at providing the opening-and-closing type roof structure which can reduce the maintenance operation | work with respect to a rail and can turn a movable roof part at any time.

  The openable roof structure of the present invention overlaps the fixed roof part that partially covers the upper part of the facility, the rail laid around the facility, the closed position that covers the remaining part above the facility, and the fixed roof part. A movable roof portion that swivels on the rail between the open position, and the travel path of the rail is covered over the entire circumference by a lid member that swirls together with the movable roof portion. To do. According to this configuration, since the rail travel path is covered with the cover member over the entire circumference, the cover member functions as snow avoidance and dust avoidance during snowfall and strong winds. For this reason, snow and dust do not enter the rail travel path, and maintenance work such as snow removal work and cleaning work on the rail can be reduced. In addition, the movable roof portion can be turned at any time without the turning of the movable roof portion being hindered by snow or dust.

  In the openable / closable roof structure of the present invention, the movable roof portion is formed in a fan shape in a plan view having an arc-shaped outer peripheral edge, and the lid member is an arc-shaped outer peripheral edge of the movable roof portion. It extends to connect both ends. According to this configuration, since an appropriate tension is applied to the movable roof portion by the lid member, distortion of the structure constituting the movable roof portion can be suppressed.

  In the openable / closable roof structure of the present invention, the movable roof portion is formed in a fan shape in plan view having a central angle of 180 degrees or more.

It is a perspective view of the dome facility which concerns on this Embodiment. It is a top view of the dome facility which concerns on this Embodiment. It is sectional drawing of the dome facility which concerns on this Embodiment. It is an enlarged view of the outer periphery of the movable roof part which concerns on this Embodiment. It is explanatory drawing of the opening / closing operation | movement of the dome roof which concerns on this Embodiment.

  Hereinafter, the present embodiment will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view of the dome facility according to the present embodiment. FIG. 2 is a top view of the dome facility according to the present embodiment. 1A shows the dome facility when the dome roof is closed, and FIG. 1B shows the dome facility when the dome roof is opened. 2A shows a dome facility in which the dome roof is omitted, and FIG. 2B shows the dome facility when the dome roof is opened. In the following description, an example in which the openable roof structure of the present invention is applied to a dome facility will be described.

  As shown in FIGS. 1 and 2, the dome facility 1 is configured by covering a field 2 sandwiched between a main stand 3 and a back stand 4 with a conical dome roof 5. The dome roof 5 opens the field 2 to the outside by turning the fixed roof portion 11 covering substantially half of the dome facility 1 so that the movable roof portion 12 covering the remaining half is overlapped. Yes. The main stand 3 is arranged inside the fixed roof portion 11, and the field 2 is arranged near the side not covered by the fixed roof portion 11 from the center of the dome facility 1. For this reason, when the movable roof portion 12 is turned so as to overlap the fixed roof portion 11, most of the field 2 is opened to the outside.

  The fixed roof portion 11 is formed in a planar fan shape having a central angle of about 180 degrees, that is, a semicircular shape in a planar view, and is fixed to a foundation (not shown) or the main stand 3 arranged on the ground. The movable roof portion 12 is formed in a fan shape (semicircle) in plan view with a central angle of 180 degrees and is slidably supported on a rail 13 provided around the dome facility 1. The movable roof portion 12 has a larger diameter than the fixed roof portion 11 and has an outer shape that can cover the fixed roof portion 11 from above. When the movable roof portion 12 slides, the movable roof portion 12 overlaps the fixed roof portion 11, so that the substantially half of the dome facility 1 is opened.

  The rail 13 is formed in a circular shape over the entire circumference of the dome facility 1. On the rail 13, a ring (lid member) 14 is installed over the entire circumference of the rail 13, and a groove 19 (see FIG. 4B) of the rail 13 is covered by the ring 14. A plurality of traveling devices 18 (see FIG. 4B) are provided on the lower surface of the ring 14, and the movable roof portion 12 is provided on the upper surface of the ring 14. On the upper surface of the ring 14, a small roof portion 15 for the back stand 4 that can turn simultaneously with the movable roof portion 12 is provided. As the plurality of traveling devices 18 travel on the rail 13, the movable roof portion 12 and the small roof portion 15 rotate along the rail 13 together with the ring 14 to open and close the dome roof 5.

  With reference to FIG.3 and FIG.4, a fixed roof part and a movable roof part are demonstrated in detail. FIG. 3 is a cross-sectional view of the dome facility according to the present embodiment. FIG. 4 is an enlarged view of the outer peripheral edge of the movable roof portion according to the present embodiment. FIG. 3 shows a cross section along the longitudinal direction of the field. 4A shows the outer peripheral edge of the movable roof portion, and FIG. 4B shows an enlarged view of the rail and the traveling device.

  As shown in FIG. 3, the fixed roof portion 11 is formed, for example, by providing a SUS metal panel on a truss frame using H steel having the same cross-sectional shape. The movable roof portion 12 is formed, for example, by stretching a Teflon (registered trademark) film material on a truss frame using H steel having the same cross-sectional shape. Since the fixed roof portion 11 and the movable roof portion 12 are formed in a conical shape (cone shape), the surface area of the entire roof is minimized. Thus, since the fixed roof part 11 and the movable roof part 12 modularize the roof structure material based on H steel, and are formed in a cone shape, it becomes possible to form easily and at low cost. Yes.

  As described above, the movable roof portion 12 and the fixed roof portion 11 that are semicircular in plan view overlap each other, so that a temporary portion during construction can be halved. Specifically, a temporary part corresponding to the fixed roof part 11 is made, and further, a movable roof part 12 is made above the fixed roof part 11, so that the fixed roof part 11 and the movable roof part 12 are made of the same temporary part. Can be manufactured. In this way, it is not necessary to make a temporary part on the entire dome roof, and it is only necessary to make a temporary part in the half range of the entire dome roof, so that the temporary cost can be greatly reduced.

  Further, the movable roof portion 12 has a semicircular shape in a plan view and a triangular shape in a side view, and has an outer peripheral edge 16 having a semicircular arc shape. The movable roof portion 12 is supported by a semicircular arc-shaped outer peripheral edge 16, and the center of gravity of the movable roof portion 12 is positioned in a region inside the outer peripheral edge 16. Therefore, the movable roof portion 12 is self-supported without being supported by the fixed roof portion 11 so as not to apply a load to the fixed roof portion 11. Further, since the movable roof portion 12 does not need to be supported by the fixed roof portion 11, the size of the movable roof portion 12 is not limited to the fixed roof portion 11. For this reason, it is possible to enlarge the movable roof portion 12 and increase the opening rate of the field 2.

  A ring 14 surrounding the dome facility 1 is provided on the outer peripheral edge 16 of the movable roof portion 12. Both ends of the outer peripheral edge 16 of the movable roof portion 12 are connected by the ring 14, and an appropriate tension is applied to the movable roof portion 12. Thereby, the rigidity of the movable roof part 12 is enhanced, and the distortion of the structure constituting the movable roof part 12 is suppressed. Moreover, as shown to FIG. 4A and B, the ring 14 has covered the groove | channel 19 of the rail 13 over the perimeter. For this reason, snow or dust does not enter the groove 19 of the rail 13 during snowfall or the like, and the travel of the traveling device 18 is not hindered by snow or dust. As described above, the ring 14 functions as a reinforcing member for the movable roof portion 12 and also functions as a snow avoidance and a dust avoidance.

  The movable roof portion 12 turns around the dome facility 1 by a plurality of traveling devices 18 traveling on the rails 13. At this time, since the entire ring 14 turns, the load of the movable roof portion 12 can be distributed over the entire circumference of the ring 14. Further, the movable roof portion 12 is reduced in weight by stretching a Teflon (registered trademark) film material on the truss frame. By reducing the weight of the movable roof portion 12, each traveling device 18 is not excessively stressed, and the movable roof portion 12 can be smoothly turned. For this reason, the movable roof portion 12 can be turned with a small amount of power.

  In addition, the movable roof portion 12 turns along the rail 13 between a closed position that covers a substantially half portion above the facility that is not covered by the fixed roof portion 11 and an open position that overlaps the fixed roof portion 11. The movable roof portion 12 is turned to the closed position when it is raining or snowing, so that the entire facility is covered with the roof to protect the user from rain and snow. When the weather is fine, the movable roof portion 12 is turned to the open position, so that the field 2 is opened to the outside and outside air is taken into the facility. In this manner, the movable roof portion 12 turns around the facility, so that the dome roof 5 above the facility is opened and closed.

  The roof of the dome roof 5 is formed in a conical shape by the fixed roof portion 11 and the movable roof portion 12. For this reason, a smooth wind flow is created and the wind load can be reduced. Moreover, since the surface of the fixed roof part 11 and the movable roof part 12 inclines linearly in side view, the snow deposited on the roof surface can be made to snow naturally. In particular, in snowy areas where snowfall and strong winds occur simultaneously, wind load can be suppressed and the amount of snow on the roof can be reduced.

  With reference to FIG. 5, the opening / closing operation | movement of a dome roof is demonstrated. FIG. 5 is an explanatory diagram of the opening / closing operation of the dome roof according to the present embodiment. 5A shows the closed state of the dome roof, and FIG. 5B shows the open state of the dome roof.

  When the dome roof 5 shown in FIG. 5A is closed, the movable roof portion 12 is turned to the closed position on the back stand 4 side. A substantially half part of the entire facility is covered with the fixed roof part 11, and the remaining substantially half part is covered with the movable roof part 12. Thereby, a part of the main stand 3 and the field 2 is covered with the fixed roof portion 11, and most of the back stand 4 and the field 2 are covered with the movable roof portion 12. By covering the entire facility with the fixed roof portion 11 and the movable roof portion 12, it is possible to prevent rain and snow from entering the dome during rainy weather or snowfall.

  When the dome roof 5 shown in FIG. 5B is opened, the movable roof portion 12 is turned 180 degrees from the closed position on the back stand 4 side to the open position on the main stand 3 side, and the movable roof portion 12 overlaps the outside of the fixed roof portion 11. It is done. At this time, since the movable roof portion 12 has an outer peripheral edge 16 that covers substantially half of the entire facility, the movable roof portion 12 turns in a self-supporting state without being supported by the fixed roof portion 11. Thereby, a part of the main stand 3 and the field 2 is covered by the fixed roof portion 11, and most of the field 2 is opened to the outside. Since most of the field 2 is exposed to the outside, outside air can be taken into the dome in fine weather.

  Moreover, since the ring 14 which covers the groove | channel 19 (refer FIG. 4B) of the rail 13 over the perimeter is provided in the movable roof part 12, snow and garbage do not enter into the groove | channel 19 of the rail 13. FIG. Thus, in the present embodiment, since the groove 19 of the rail 13 is covered, the turning of the movable roof portion 12 is not hindered by snow, dust, or the like that has entered the groove 19 of the rail 13. Since both ends of the outer peripheral edge 16 of the movable roof portion 12 are reinforced by the rail 13, deformation of the outer peripheral edge 16 having low rigidity is suppressed. With such a configuration, the turning of the movable roof portion 12 is not hindered, the distortion of the outer peripheral edge 16 of the movable roof portion 12 is suppressed, and the movable roof portion 12 can be smoothly rotated.

  A small roof portion 15 is provided on the ring 14 at a position facing the movable roof portion 12 across the field 2. The small roof portion 15 pivots integrally with the movable roof portion 12, and is positioned outside the main stand 3 when the dome roof 5 is closed (see FIG. 5A), and covers the back stand 4 when the dome roof 5 is opened (see FIG. 5A). (See FIG. 5B). Thus, by providing the small roof portion 15 that rotates integrally with the movable roof portion 12, the back stand 4 can be covered not only when the dome roof 5 is closed but also when the dome roof 5 is opened. Yes.

  As described above, according to the present embodiment, since the groove 19 of the rail 13 is covered with the ring 14 over the entire circumference, the ring 14 functions as snow avoidance and dust avoidance during snowfall and strong winds. For this reason, snow and dust do not enter the groove 19 of the rail 13, and maintenance work such as snow removal work and cleaning work on the rail 13 can be reduced. Moreover, the movable roof part 12 can be turned at any time without the turning of the movable roof part 12 being hindered by snow or dust.

  The present invention is not limited to the above embodiments, and can be implemented with various modifications. In the above-described embodiment, the size, shape, and the like illustrated in the accompanying drawings are not limited to this, and can be appropriately changed within a range in which the effect of the present invention is exhibited.

However, the present invention is not limited to this configuration. The ring 14 may not be provided in the lower part of the movable roof portion 12. In this case, the lid member that covers the entire circumference of the rail 13 is configured by an outer peripheral edge 16 of the movable roof portion 12 and an arcuate member that connects both ends of the outer peripheral edge 16.

  In the present embodiment, the travel path is formed by the groove 19 formed in the rail 13, but the present invention is not limited to this configuration. The travel path of the rail 13 may be formed by an annular convex portion, as long as the movable roof portion 12 is guided so as to be able to turn. In this case, the ring 14 is provided with a concave portion that engages with the annular convex portion.

  Moreover, in this Embodiment, although the fixed roof part 11 and the movable roof part 12 were formed in the semicircle shape which is a planar view fan shape with a center angle of 180 degree | times, it is not limited to this structure. The movable roof portion 12 only needs to have an outer peripheral edge 16 having a length that allows the movable roof portion 12 to stand on its own, and the movable roof portion 12 may be formed in a fan shape in plan view with a central angle of 180 degrees or more.

  Moreover, in this Embodiment, although the roof surface of the fixed roof part 11 and the movable roof part 12 was set as the structure which inclines linearly in side view, it is not limited to this structure. The roof surfaces of the fixed roof portion 11 and the movable roof portion 12 may be curved.

  Moreover, in this Embodiment, although the conical dome roof was formed by the fixed roof part 11 and the movable roof part 12, it is not limited to this structure.
