The simulator dome 1 according to the present embodiment has the above-described configuration, and then an example of an assembly method of the simulator dome 1 will be described.
First, in order to assemble the screen portion 2 of the simulator dome 1, one main body rib 8 is fixed on a base (not shown), and the flange portion of the main body rib 8 is brought into contact with one side portion thereof to form a fixing screw 18. Temporarily fix with nut 19. Next, the flanges of the main body panel 9 are brought into contact with both sides of the main body ribs 8 installed at predetermined intervals, and the fixing bolts 18 and nuts 19 are fastened together, and the main body ribs 8 and the main body panel 9 are sequentially tightened in the same manner. Will be connected.
Then, the flange portion of the final main body panel 9 is fastened and fixed together with the flange portion temporarily fixed to the first main body rib 8 with the fixing bolt 18 and the nut 19, so that the substantially annular screen portion 2 is formed. Further, if two sets of support frames 13 are fixed inside the beam portion 12 of the top plate portion 6 with fixing bolts 18 and nuts 19, the screen portion 2 can be firmly fixed.

Next, when assembling the ceiling portion 3, the lower end portion of the ceiling side rib 15 is fixed to the beam portion 12 of the top plate portion 6 or the main body rib 8 with bolts or the like. Then, the flange portion 16a of the ceiling side panel 16 is brought into contact with one side portion of the ceiling side rib 15, and the fixing bolt 18 and the nut 19 are tightened and temporarily fixed at the respective screw hole portions 15a and 16b. Next, the flange portions 16a of the ceiling side panel 16 are brought into contact with both sides of the fixed ceiling side rib 15 and fastened together with the fixing screw 18 and the nut 19, and the ceiling side rib 15 and the ceiling side panel 16 are connected in the same manner in order. To go.
Then, the ceiling portion 3 on the upper part of the substantially spherical surface is formed by fastening and fixing the flange portion 16a of the last ceiling side panel 16 together with the flange portion 16a temporarily fixed to the first ceiling side rib 15 with fixing bolts 18 and nuts 19. NS.

At the end of assembling the ceiling portion 3, a gap is generated between the last ceiling side panel 16 and the first ceiling side rib 15 due to an assembly error, a manufacturing error of each part, or the like, or the ceiling portion 3 overlaps with each other. Errors may occur. In this case, since the ceiling-side ribs 15 are plate-shaped, the gaps can be filled or the ceiling-side panels 16 can be filled by bringing a plurality of sheets into close contact with each other, adjusting the thickness of the ceiling-side ribs 15 by increasing or decreasing them, or replacing them with different ones. It is possible to adjust each other by eliminating the overlap with the ceiling.
Then, by fixing the ventilation device 23 on the annular fixed frame 22 provided on the top of each ceiling-side rib 15 with bolts or the like, the ceiling-side rib 15 of the ceiling portion 3 can obtain a stronger and more rigid skeleton structure. Be done. A cover or the like may be installed on the top of each ceiling-side rib 15 instead of the ventilation device 23.
Further, the plurality of projectors 10, the light-shielding member 25, and the like may be appropriately attached during the assembly process or after the assembly of the screen portion 2 and the ceiling portion 3 is completed.

As described above, according to the simulator dome 1 according to the present embodiment, the ceiling portion 3 has the ceiling side rib 15 and the flange portion 16a of the ceiling side panel 16 formed separately so as to project to the outside of the ceiling side panel 16 and are fixed bolts. Since the 18 and the nut 19 are fastened together and fixed, high rigidity can be obtained while being relatively lightweight, and assembly is easy. By fixing the ventilation device 23 to the upper end of each ceiling side rib 15, the skeleton structure is further strengthened.
Therefore, it has higher strength than the configuration in which the ribs of the panel-shaped split body are connected to each other to be sequentially connected as in the conventional simulator dome.

Moreover, by forming the ceiling-side rib 15 and the ceiling-side panel 16 individually, the mold at the time of manufacturing is simplified, and the degree of freedom in designing the ceiling-side rib 15 and the ceiling-side panel 16 is increased.
The error that occurs when assembling the ceiling side rib 15 and the ceiling side panel 16 can be eliminated by stacking a plurality of ceiling side ribs 15, replacing them with different thicknesses, or adjusting the thickness.
It should be noted that the same effect can be exerted not only on the ceiling portion 3 but also on the main body rib 8 and the main body panel 9 in the screen portion 2.
