(First embodiment)
FIG. 1 is a view of the framework structure according to the first embodiment of the present invention as viewed obliquely from above.

  This frame structure is applied to a dome-shaped structure, and includes a plurality of vertical frames 1 provided radially from the apex O, and a horizontal frame 2 provided in an intersecting manner across each vertical frame 1. Each vertical frame 1 has a substantially arc shape, and each horizontal frame 2 has a polygonal shape with a shorter radius toward the upper side, in this embodiment, a regular hexagonal shape. In FIG. 1, the vertical frame 1 portion and the horizontal frame 2 portion which are the back side are omitted.

  A top connecting member 6 is disposed at the upper end of each vertical frame 1. The connecting member 3 is located below the top connecting member 6 and intersects each vertical frame 1 and each horizontal frame 2. Is arranged. In the present embodiment, a total of 48 connecting members 3 are arranged, three at regular intervals in the direction along the vertical frame 1 and 16 at regular intervals in the direction along the horizontal frame 2. Each vertical frame 1 is constituted by three divided vertical frames 11 connected by a connecting member 3, and each horizontal frame 2 is also constituted by 16 divided horizontal frames 12 connected by a connecting member 3.

  As shown in FIG. 2, the divided vertical frame 11 is formed in a substantially trapezoidal shape having a wide outer side 11a and a narrow inner side 11b, and has a side 11c near the vertex O and a side 11d on the opposite side. By arranging so as to face the same position on the vertical line V passing through the vertex O, the vertical frame 1 having a substantially arc shape is configured. In the present embodiment, since the outer side 11a is linear, the entire vertical frame 1 is substantially arc-shaped as described above, but by making the outer side 11a curved, the entire vertical frame 1 is It can also be arcuate as shown by the dashed line.

  In the state between the adjacent vertical frames 1, the outer side is wider than the inner side, and the separation interval is wider toward the lower part, and the separation interval is narrower toward the upper part. And in this embodiment, since the connection member 3 is arrange | positioned at equal intervals in the direction along the vertical frame 1 as above-mentioned, it is possible to use the thing of the same shape as the division | segmentation vertical frame 11.

  On the other hand, the divided horizontal frame 12 is formed in a shape corresponding to the interval between adjacent vertical frames 1, that is, in a substantially rectangular shape with a wide outer side 12 a and a narrow inner side 12 b, and both side sides 12 c and 12 d are vertical lines V. It is arranged to face the upper position. However, with respect to the divided horizontal frame 12, since the radius becomes shorter as the horizontal frame 2 of each step is located on the upper side, it is not possible to use the same shape, but the horizontal frame 2 is a regular 16 corners. By adopting the shape, it is possible to use the same shape as those located in the same step.

As shown in FIG. 3, the connecting member 3 extends in the connecting direction of the divided vertical frame 11 and the divided horizontal frame 12 toward the axial center of the rod 4 on the outer side of the cylindrical bar 4 and the bar 4. The connecting piece 5 has a rectangular plate shape protruding like this, and the base end of the connecting piece 5 is connected to the rod body 4, and is arranged so that the axis of the rod body 4 faces the vertical line V. . In addition, as shown in FIG. 2, the connecting member 3 is located between upper and lower adjacent divided vertical frames 11, and the axial direction of the rod body 4 is a line connecting both ends of the outer sides 11 a in both divided vertical frames 11. is disposed an angle θ minute the mechanic so that the direction that bisects. In addition, the connecting members 3 arranged at substantially the same height position have the same height position on the vertical line V in the direction in which the rod 4 faces, for example, in this embodiment, the installation surface of the frame structure and the vertical line V intersect. It is provided so as to face the point v1. At this time, when all the divided vertical frames 11 in the direction along the vertical frame 1 have the same shape as in the present embodiment, the following can be said. That is, four connecting members 3 are provided at equal intervals along the direction of the vertical frame 1, and each connecting member 3 has an outer side higher than the inner side and an upper side connecting member 3 below the lower side connecting member 3. 3 is arranged with a large gradient angle, and the angle difference between the gradient of the upper connecting member 3 and the gradient of the lower connecting member 3 is constant.

  As the connecting member 3, three connecting pieces 5 and four connecting pieces 5 are used. This will be described with reference to FIG. 4. The four connecting pieces 5 a, 5 b, 5 c and 5 d connected to the two divided vertical frames 11 as well as the two divided horizontal frames 12 on both sides, Some have three connecting pieces 5a, 5b, and 5d connected to two divided horizontal frames 12 and one divided vertical frame 11 on one side. The connecting member 3 having the three connecting pieces 5 is used for both end positions in the height direction, and the connecting member 3 having the four connecting pieces 5 is used for the other height positions.

  Of the connecting pieces 5 described above, the connecting pieces 5a and 5c for the vertical frame connected to the divided vertical frame 11 do not need to change the arrangement angle because the entire vertical frame 1 is perpendicular to the horizontal plane. The angle θ1 around the axis of the bar 4 in the connecting pieces 5b and 5d for the horizontal frame connected to the two divided horizontal frames 12 depends on the polygonal shape of the horizontal frame 2 and the angle at which the bar 4 is tilted with respect to the horizontal plane. It is necessary to have a unique angle. For this reason, the same connection member 3 used for the same height step of the horizontal frame 2 is not a problem, but different connection members 3 in which the angle θ1 is adjusted to a specific angle are used at different height steps. ing.

  On the other hand, as shown in FIG. 5, concave grooves 13 are formed on both sides 11c and 11d of the divided vertical frame 11, and concave grooves 14 are also formed on both sides 12c and 12d of the divided horizontal frame 12. Yes. That is, the grooves 13 and 14 are formed on the crossing end faces of the divided vertical frame 11 and the divided horizontal frame 12. Then, by inserting the connecting piece 5 into the concave grooves 13 and 14 of the divided vertical frame 11 and the divided horizontal frame 12, the divided vertical frame 11 and the divided horizontal frame 12 are connected via the connecting member 3. At this time, the through holes 15 and 16 provided at both ends of the divided vertical frame 11 and the divided horizontal frame 12 and the attachment holes 5f provided in the connecting piece 5 are made to coincide with each other. Then, for example, bolts and nuts are stopped in the through holes 15 and 16 as a means for preventing the removal. This prevents the connecting piece 5 from coming out of the concave grooves 13 and 14.

  FIG. 6 is a perspective view showing the top connecting member 6.

  The top connecting member 6 connects the divided vertical frames 11 near the vertex O, and connecting pieces 6b connected to the divided vertical frames 11 are radially provided on the outer periphery of the cylindrical member 6a. The interval a on the proximal end side of the adjacent connecting pieces 6b is set according to the thickness of the divided vertical frame 11, and the outer diameter of the cylindrical member 6a is also set based on this. Instead of the hollow cylindrical member 6a, a solid cylindrical member, that is, a columnar member can be used.

  The number of the connecting pieces 6b is provided in accordance with the number of the divided vertical frames 11 to be connected, and the concave grooves 13 of the divided vertical frames 11 are inserted, whereby all the divided vertical frames 11 near the vertex O have one top portion. It is connected by the connecting member 6 for use.

  Next, an example of manufacturing a frame structure having this configuration will be described.

  First, 16 divided horizontal frames 12 are arranged on the installation location and connected by the connecting member 3 having three connecting pieces 5. Subsequently, the vertical frame connecting piece 5 remaining on the connecting member 3 is connected to the lower side 11d of the first-stage divided vertical frame 11, and the vertex O in each first-stage divided vertical frame 11 is connected. One lower frame connecting piece 5 provided in the connecting member 3 having the four connecting pieces 5 is connected to each of the side sides 11c close to each other, and subsequently, between the connecting members 3 arranged side by side. In addition, the divided horizontal frame 12 is connected. As a result, the unit U portion in the first stage composed of the four connecting members 3 adjacent to each other and the two divided vertical frames 11 and the two divided horizontal frames 12 connected by these connecting members 3 is viewed from the outside. Assembled into a trapezoidal shape.

  Next, the vertical frame connecting piece 5 remaining on the first-stage unit U is connected to the lower side 11d of the second-stage divided vertical frame 11, and the second-stage divided vertical frame 11 For each of the sides 11c near the vertex O, the lower frame connecting piece 5 having the four connecting pieces 5 is connected, and subsequently, between these side by side connecting members 3, The divided horizontal frames 12 are connected. As a result, the second-stage unit U portion composed of the four connecting members 3 that are close to each other and the two divided vertical frames 11 and the two divided horizontal frames 12 that are connected by these connecting members 3 is from the outside. It is assembled into a trapezoidal shape.

  Next, the vertical frame connecting piece 5 remaining on the second-stage unit U is connected to the third-stage divided vertical frame 11, and the top side 11 c of the third-stage divided vertical frame 11 is connected to the top portion. The connecting piece 6b of the connecting member 6 is connected. Thereby, the frame structure of FIG. 1 is completed.

  It should be noted that the bolts and nuts serving as the prevention means may be attached all at once after inserting the connecting pieces into the concave grooves, or may be attached one by one or at a plurality of places.

  In the frame structure of the present embodiment manufactured as described above, the two divided vertical frames 11 and the two divided horizontal frames 12 connected by the four connecting members 3 that are close to each other are viewed from the outside. Since it is assembled into a shape, it is possible to reduce the number of frame members required for the assembly, as compared with the case of assembling into a triangular prism, thereby simplifying the construction. The connecting member 3 has three or four connecting pieces 5 connected to two adjacent divided horizontal frames 12 and at least one divided vertical frame 11, and each connecting piece 5 is divided into the divided vertical frame 11 and the divided pieces. Since the divided vertical frame 11 and the divided horizontal frame 12 are connected by being inserted into the concave grooves 13 and 14 formed in the respective crossing end faces of the horizontal frame 12, first, the lowest step is made, and then Thus, it is possible to easily manufacture by adding the upper step.

  In the above-described example of manufacturing the frame structure, an example in which the frame structure is added from the lower stage to the upper stage is described. However, the frame structure of the present invention supports the top connection member 6 in a state of floating from the ground. By using the members, it is also possible to create from the upper stage to the lower stage.

  Further, in the case of the present embodiment, since the divided vertical frame 11 is formed in a substantially trapezoidal shape with the outside wide and the inside narrow, the side edges 11c and 11d are inclined so as to approach the inner side. Therefore, the side edges 11c and 11d of the adjacent divided vertical frames 11 are arcuate only by abutting. Further, since the divided horizontal frame 12 is also formed in a substantially trapezoidal shape having a wide outside and a narrow inside, both side edges 12c and 12d are inclined so that the inner side is approached. The side sides 12c and 12d are circular just by butting. Further, since the connecting member 3 is arranged so as to face the vertical line V passing through the vertex O, all the divided horizontal frames arranged at the same height position on each of the two side edges 12c and 12d in the divided horizontal frame 12 are provided. 12, the sizes of the divided horizontal frames 12 can be made common.

  Furthermore, the connecting member 3 positioned between the vertically divided vertical frames 11 adjacent to each other has an equal angle θ between the line segments L connecting the upper and lower ends of the outer side 11a of the both divided vertical frames 11 in the direction of the rod 4. Since they are arranged so as to be divided, the angle between the side edge 11c of the lower divided vertical frame 11 and the side edge 11d of the upper divided vertical frame 11 can be made uniform. It becomes possible. In particular, when the direction in which the rod (axial center) 4 of the connecting member 3 arranged at substantially the same height is directed to the same height on the vertical line V, the side 11c of the lower divided vertical frame 11 is provided. And the side 11d of the upper divided vertical frame 11 can be made uniform in one round.

  Furthermore, a plurality of connecting members 3 are provided along the direction of the vertical frame 1, and each connecting member 3 has an outer side higher than the inner side, and the upper one has a larger gradient than the lower one. The two side sides 11c and 11d of each divided vertical frame 11 are arranged so that the angle difference between the gradient of the upper connecting member 3 and the gradient of the lower connecting member 3 is constant. Can be made uniform, and the size of all the divided vertical frames 11 can be made common.

  Furthermore, in the present embodiment, since the top connecting member 6 in which the connecting pieces 6b are radially arranged on the outer periphery of the cylindrical member 6a is used, it is possible to omit the divided horizontal frame, thereby making it possible to manufacture a frame structure. It becomes possible to make it easier. In addition, since it is not necessary to attach the divided horizontal frame, there is an advantage that it can be easily manufactured even in a narrow place at the top. However, the divided vertical frame 11 and the divided horizontal frame 12 may be connected by the connecting member 3 without using the top connecting member 6.

  In the above embodiment, the outer edge 11a of each divided vertical frame 11 is a straight line and each vertical frame 1 is substantially arcuate. However, the present invention is not limited to this, and the outer edge of each divided vertical frame 11 is not limited thereto. 11a may be arcuate and the entire vertical frame 1 may be arcuate. In the case of such a configuration, when the dome-shaped tent curtain is put on the frame structure of the present embodiment, the outer edge of the vertical frame 1 and the outer edge of the horizontal frame 2 are formed in a shape along the curved surface of the tent curtain. Since they can be made to coincide, it is possible to increase the number of supporting portions of the tent curtain, and it is possible to support the tent curtain in a stable state.

The distance between the base end sides of the horizontal frame connecting pieces 5b and 5d and the arc-shaped member 31b is set to be approximately the same as the thickness of the cylindrical rod 31a.

  In the case of this connecting member 31, the meat portion of the cylindrical rod 31a passes through the opening surrounded by the connecting pieces 5b, 5d for the horizontal frame, the arc-shaped member 31b, and the two extending portions 31c. Therefore, the horizontal frame connecting pieces 5b and 5d can be rotated with respect to the cylindrical rod 31a. Thus, the horizontal frame connecting pieces 5b and 5d can adjust the angle around the axis of the cylindrical rod 31a. In addition, since the distance between the base end side of the connecting pieces 5b and 5d for the horizontal frame and the arc-shaped member 31b is set to be substantially the same as the thickness of the cylindrical rod 31a, the integrated horizontal frame It is possible to prevent the connecting pieces 5b and 5d and the arc-shaped member 31b from rattling with respect to the cylindrical rod body 31a.
