The assembly structure 100 has the appearance shown in FIG. 1 and is a structure capable of accommodating people, animals, or objects inside. It can be used as a simple tent or a hut for pets. An opening 122 is provided in the lower part of the assembly structure 100 (specifically, the body structure 120) as shown in FIG.

As shown in FIG. 1, the assembly structure 100 is composed of a dome structure unit 110 forming the upper part of the structure and a cylindrical body structure 120 supporting the dome structure unit 110 from below. The dome structure unit 110 has an outer dome structure 80 and an inner dome structure 60 arranged inside the outer dome structure 80, as shown in FIG.
For convenience of explanation, the outer dome structure 80 in FIG. 2 is illustrated with a portion of the panel (hereinafter referred to as outer panel 82) that constitutes the outer dome structure removed.

The inner dome structure 60, the outer dome structure 80, and the fuselage structure 120 are each prefabricated structures constructed by combining multiple panels. The panels forming each structure are made of, for example, corrugated cardboard made of paper, that is, corrugated cardboard sheets. A corrugated cardboard sheet has a laminated structure in which a core made of corrugated paper is sandwiched between two flat sheets of paper, and the paper quality may be of any type, and various types of coatings may be applied.
It should be noted that the body structure 120 is not limited to a cardboard sheet, and may be formed by molding or processing a metal or resin material into a cylindrical shape.

[Outer dome structure]
The outer dome structure 80 will be described with reference to FIGS. 2, 3 and 4 above. 3 is a perspective view of the outer panel 82 viewed from the inside, and FIG. 4 is an enlarged view of a portion of the bottom portion 81 of the outer dome structure 80 in FIG.

The outer dome structure 80 is constructed by preparing a plurality of (specifically, 12) outer panels 82 shown in FIG. 3, arranging the plurality of outer panels 82 in a dome shape, and joining the panels together.

Each outer panel 82 is composed of a plurality of panel pieces 84. In the case of the configuration shown in FIG. 3, four panel pieces 84 are used and two adjacent panel pieces are joined together. When joining the panel pieces together, the connecting projections 85 provided on the outer edge portions of the panel pieces 84 are bent substantially perpendicularly to the panel body other than the connecting projections 85 . Then, the two panel pieces 84 are joined together by bringing the connecting projections 85 of the two adjacent panel pieces 84 into contact with each other and connecting the connecting projections with a binding tool or the like.

In the outer panel 82 constructed in the manner described above, as shown in FIG. Also, when joining the outer panels together, the connecting projections 85 erected on the outer edges of the respective outer panels 82 are connected to each other.

The outer joint hole 88 functions as an outer dome joined portion, which will be described later.

[Inner dome structure]
The inner dome structure 60 will be described with reference to FIGS. 2 and 5 already mentioned. 5 is a perspective view of the bent inner panel 10 as seen from the outside.

The inner dome structure 60 is a dome body smaller in size than the outer dome structure 80 , and is assembled to the outer dome structure 80 while being placed inside the outer dome structure 80 . As a result, the connecting protrusions 85 protruding from the inner surface of the outer dome structure 80 are hidden by the inner dome structure 60, and the design of the inner surface of the assembly structure 100, particularly the ceiling portion, can be improved. .

Also, the inner surface of the inner dome structure 60 is not provided with a portion corresponding to the connecting projection 85 of the outer dome structure 80 . Therefore, the inner surface of the inner dome structure 60 becomes a smooth curved surface without irregularities, and can be used for purposes such as projecting images on this curved surface. In addition, when a gap (joint) is formed between the outer panels in the outer dome structure 80, even if external light leaks into the dome through the gap, the inner dome structure 60 can block it. .

The inner dome structure 60 is constructed by combining a plurality of (specifically, 12) panels, and more specifically, by arranging a plurality of panels in a dome shape and joining the panels together. Panels forming the inner dome structure 60 (hereinafter referred to as the inner panel 10) are used in a three-dimensionally bent state as shown in FIG. The state in which the inner panel 10 is bent means that the outer surface of the panel body 12 of the inner panel 10 is bent so as to form a curved surface. The point with P) is bent so as to protrude outward. Here, the point P is the intersection of the diagonal lines of the quadrangle formed by the outer edge of the panel body 12 when the panel body 12 is in a bent state.

Also, each of the inner panels 10 forming the inner dome structure 60 has the same shape. That is, the inner dome structure 60 is composed of one type of inner panel 10 . Since the inner dome structure 60 is composed of only one type of panel, the inner dome structure 60 can be assembled more easily.

In addition, since only one type of inner panel 10 is used, the number of tools such as molds for manufacturing the inner panel 10 is reduced, which facilitates panel manufacturing and reduces panel manufacturing costs. Furthermore, when the inner dome structure 60 is assembled at a location where the assembly structure 100 is used, the inner panel 10 is transported to that location. The panels 10 can be stacked and transported. In addition, a plurality of inner panels 10 can be stacked and stored at a place of use. As a result, transportation, storage, etc. of the inner panel 10 become easier.

[Composition of inner panel]
The construction of the inner panel 10 will now be described with reference to FIGS. FIG. 6 is a view showing the inner panel 10 in a sheet state before being bent, and is a view of the inner panel 10 viewed from the inside (back side). FIG. 7 is a front view of the inner panel 10 in a bent state, and more specifically, a view showing the outer surface of the inner panel 10 when looking straight ahead at the point P mentioned above.

As described above, each of the plurality of inner panels 10 forming the inner dome structure 60 has the same shape, and the inner panels 10 have the same configuration. will be described.

Further, hereinafter, for convenience of explanation, when the inner panel 10 in a bent state (the inner panel 10 shown in FIG. 7) is viewed from the outside, the side proceeding clockwise around the point P will be referred to as the “downstream side”. , and the opposite side is called the "upstream side".

The inner panel 10 is composed of one sheet, and includes a panel body 12 and a joint 40 provided along the outer edge of the panel body 12, as shown in FIGS.

As shown in FIG. 6, the panel body 12 is divided into a plurality of unit portions, specifically, six unit portions 21 to 26 by a plurality of folding lines L1 formed in the panel body 12. As shown in FIG. Each of the six unit portions 21 to 26 has a triangular shape, and among them, five unit portions 21 to 25 are arranged around a point P as shown in FIG. ) are placed.

The first unit portion 21 is a substantially equilateral triangular portion. A substantially isosceles triangular second unit portion 22 and third unit portion 23 are provided on both sides of the first unit portion 21 . The second unit portion 22 and the third unit portion 23 are in a congruent relationship, the second unit portion 22 shares one side with the first unit portion 21, and the third unit portion 23 is the second unit portion. shares one side with the first unit portion 21 on the side opposite to the unit portion 22 of the . The fourth unit portion 24 is a substantially right-angled portion and shares one side with the second unit portion 22 at a position different from that of the first unit portion 21 . The fifth unit portion 25 is congruent with the fourth unit portion 24 and shares one side with the third unit portion 23 at a position different from that of the first unit portion 21 . The sixth unit portion 26 is an approximately isosceles triangular portion, the base of which is one side of the first unit portion 21 (the side at a position different from that of the second unit portion 22 and the third unit portion 23). ).

Moreover, in the panel body 12 before the panel body 12 is bent, as shown in FIG. An overlap margin portion 27 is provided. The overlapping portion 27 overlaps the fourth unit portion 24 when the panel body 12 is bent, and is continuous with the fifth unit portion 25 . A bending line L2 is provided at the boundary position between the fifth unit portion 25 and the overlapping margin portion 27. As shown in FIG.

Further, as shown in FIG. 6, a notch 28 is provided between the fourth unit portion 24 and the overlapping margin portion 27 in the panel body 12 before the panel body 12 is bent. The notch 28 is a cutting line extending linearly along one side of the fourth unit portion 24 (the side located on the side of the fifth unit portion 25) except for the portion where the later-described insertion piece 29 is provided. be. Here, as shown in FIG. 6, the fourth unit portion 24 and the overlap portion 27 correspond to two portions of the panel body 12 located on opposite sides of the notch 28 .

Further, as shown in FIG. 6, a substantially trapezoidal insertion piece 29 protrudes toward the fifth unit portion 25 from the side of the fourth unit portion 24 on which the notch 28 is located. In other words, the cut 28 described above is formed while curving along the outer edge of the insertion piece 29 at its midpoint. On the other hand, a slit-shaped insertion hole 30 is provided at a boundary position between the fifth unit portion 25 and the overlapping margin portion 27, more specifically, at a position corresponding to the insertion piece 29 on the bending line L2. The insertion piece 29 is inserted into the insertion hole 30 when the panel body 12 is bent.

The trapezoidal insertion piece 29 is constricted at the base portion, and the width of the portion adjacent to the base portion on the tip side of the insertion piece 29 is longer than the width of the insertion piece 29 . The width dimension in the longitudinal direction of the insertion hole 30 is set shorter than the longest dimension in the width direction of the insertion piece 29 . Such a shape of the insertion piece 29 functions as a retaining structure that prevents the insertion piece 29 from coming off from the insertion hole 30 .

The panel body 12 configured as described above is bent along a plurality of folding lines L1 when assembling the inner dome structure 60 (that is, combining a plurality of inner panels 10). At this time, since the notch 28 is provided, the panel body 12 can be bent so that a portion of the fourth unit portion 24 and the overlapping margin portion 27 overlap as shown in FIG. Specifically, the panel body 12 is bent so that one side of the fourth unit portion 24 (the side on which the notch 28 is located) and one side of the fifth unit portion 25 (the side forming the folding line L2) are aligned. be done. As a result, the panel main body 12 has a three-dimensional shape, more specifically, the surface of the panel main body 12 forms a curved surface, more specifically, a portion of a spherical surface.

Further, by inserting the insertion piece 29 into the insertion hole 30, a state in which a portion of the fourth unit portion 24 and the overlapping margin portion 27 are overlapped can be stably maintained. Note that the means for maintaining the overlapping state of the fourth unit portion 24 and the overlapping margin portion 27 is not limited to the above configuration. Both parts may be fixed by tape or the like.

Further, the outer edge of the panel main body 12 in the bent state forms a substantially square shape in a front view as shown in FIG. One diagonal CL in this substantially square is the longer diagonal and bisects the surface of the panel body 12 in the bent state. That is, the substantially quadrangular shape is line-symmetrical with respect to the diagonal line CL.

The joint portion 40 is formed of a projection projecting from the outer edge of the panel body 12 to the outside of the panel body 12, and is used when joining the panels. That is, each inner panel 10 is joined to another inner panel 10 adjacent to the inner dome structure 60 by the joining portion 40 when the panels are joined. The time of joining the panels means the time of joining two inner panels arranged at positions adjacent to each other in the inner dome structure 60 .

In addition, "joining" means that parts are joined together, and engagement including meshing and hooking, fitting including concave-convex fitting and fitting, insertion and insertion, and adhesion are all It can be included in the category of conjugation. Similarly, joining using a fastener such as a stapler or tape, or a binding tool such as an Insulok may be used.

6 and 7, the joint portion 40 preferably has at least two types of projections, specifically flap-shaped joint pieces 41 to 45 and a substantially trapezoidal shape. may be provided with a junction projection 46. However, the configuration is not limited to this, and a configuration in which the joint portion 40 does not include the joint projections 46 but only the joint pieces 41 to 45 may be employed.

The joint pieces 41 to 45 are quadrilateral portions extending along the outer edge of the panel body 12, and more specifically, they have a quadrilateral shape such as a parallelogram, a trapezoid, or similar. The shape of the joining piece is not particularly limited, and may be rectangular or square. The joining pieces 41 to 45 are joined to the joining piece missing portion 51 by engaging the joining piece missing portion 51 along the surface of the panel body 12 when joining the panels (see FIG. 8). The joining piece missing portion 51 corresponds to the joined portion 50 and is a part of the panel body 12, and is a region of the outer edge of the panel body 12 where the joining pieces 41 to 45 do not protrude (hereinafter referred to as missing region Ra). is the part adjacent to

As shown in FIG. 7, the outer edge of the panel body 12 has a mixture of a lacking area Ra and an area where the joint pieces 41 to 45 protrude (hereinafter referred to as a protruding area Rb). Therefore, in the inner panel 10, the portions adjacent to the projecting region Rb (that is, the joining pieces 41 to 45) are convex portions, and the portions adjacent to the missing region Ra are concave portions.

In addition, as shown in FIG. 6 , a bending line L3 is formed along the projecting region Rb of the outer edge of the panel body 12 . The fold line L3 is provided on the outer or inner surface of the inner panel 10, preferably on the outer surface. In addition, in FIG. 6, the bending line L3 formed on the outer surface of the inner panel 10 is indicated by a broken line. The bending lines L3 are configured by, for example, rows of recesses (embossments) that are continuously or intermittently provided at the positions where the bending lines L3 are formed, such as perforations.

The joining projection 46 protrudes from the missing region Ra of the outer edge of the panel body 12 and extends long along the outer edge of the panel body 12. remarkably small compared to The joining protrusion 46 is joined to the joining hole 52 by inserting it into the joining hole 52 of the other adjacent inner panel 10 along the surface of the panel main body 12 when joining the panels (see FIG. 8). ). The joining hole 52 corresponds to the joined portion 50 , is a slit-shaped hole, and is provided in the projecting region Rb of the outer edge of the panel body 12 as shown in FIG. 6 .
As described above, the joining hole 52 corresponds to the part to be joined 50 because the joining protrusion 46 is inserted into the joining hole 52 and joined to the joining protrusion 46. In other words, the part to be joined 50 is the joining protrusion. A joint hole 52 is provided as a portion to be joined with 46 .

The trapezoidal joint projection 46 is constricted at the root portion, and the width of the portion adjacent to the root portion on the tip side of the joint projection 46 is longer than the width of the joint hole 52 . Also, the width dimension in the longitudinal direction of the joint hole 52 is set shorter than the longest dimension in the width direction of the joint projection 46 . Such a shape of the joint protrusion 46 functions as a retaining structure that prevents the joint protrusion 46 from coming off from the joint hole 52 .

In the bent panel body 12, as shown in FIG. 7, one or more joint pieces 41 are formed along each side of the quadrangle formed by the outer edge of the panel body 12 (that is, each of the four sides included in the outer edge). . . . 45 and one or more mating projections 46 are provided. Also, one or more joint piece missing portions 51 and one or more joint holes 52 are provided along each of the four sides. As described above, the inner panel 10 is provided with a plurality of joint portions 40 and a plurality of joined portions 50, respectively. In a particularly preferred embodiment (the embodiment shown in FIGS. 6 and 7), the positions of the joint portion 40 and the joint portion 50 of each inner panel 10 are symmetrical with respect to the diagonal line CL.

Specifically, of the outer edge, of the side forming one side of the fourth unit portion 24 (hereinafter referred to as the first side), the upstream half area is the missing area Ra, and the downstream half area is the missing area Ra. is the projecting region Rb. As shown in FIG. 7, a substantially parallelogram-shaped joint piece 41 protrudes from the protruding region Rb of the first side. The upstream edge side of the joint piece 41 is inclined toward the upstream side as it separates from the first side. Further, as shown in FIG. 7, a joining projection 46 protrudes from substantially the center of the missing region Ra of the first side.

On the other hand, a portion of the panel body 12 adjacent to the missing region Ra on the first side becomes a joining piece missing portion 51 as the joined portion 50 . Further, as shown in FIG. 7, a joint hole 52 as a joint portion 50 is formed at the boundary position between the joint piece 41 and the panel body 12 (that is, on the projecting region Rb).

Of the above outer edges, the side that is symmetrical to the first side with respect to the diagonal line CL and constitutes one side of the fifth unit portion 25 (hereinafter referred to as the second side) lacks the upstream half area. This is the region Ra, and the downstream half region is the projecting region Rb.

[Method for Assembling the Inner Dome Structure]
A method of assembling the inner dome structure 60 will now be described with reference to FIGS.

The inner dome structure 60 is constructed by combining a plurality of, for example, twelve inner panels 10 . Here, of the inner dome structure 60 , the dish-shaped top portion is formed by combining four inner panels 10 , and the cylindrical side body portion is formed by combining eight inner panels 10 . be. Here, the inner panel 10 forming the side body portion corresponds to the lower panel. The lower panel is positioned such that when the inner dome structure 60 is placed inside the outer dome structure 80, part of the outer edge of the panel body 12 faces the bottom portion 81 of the outer dome structure 80. It's about.

When assembling the inner dome structure 60, the panel main body 12 of each of the plurality of inner panels 10 is bent so that its surface becomes a curved surface, and the inner panels 10 with the panel main bodies 12 bent are combined.
In the following description, the inner panel 10 with the panel body 12 bent is simply referred to as the "inner panel 10".

In order to combine the twelve inner panels 10, two inner panels (hereinafter referred to as two adjacent panels) of the twelve inner panels 10 that are positioned adjacent to each other in the inner dome structure 60 are joined together. do. The two adjacent panels are then joined by joints 40 on each of the two adjacent panels, as shown in FIGS. 8-10.

Specifically, of the two adjacent panels, the joint portion 40 provided by one adjacent panel is aligned with the joint portion 50 provided by the other adjacent panel in the direction in which the two adjacent panels are arranged (i.e., the adjacent direction). ). Similarly, the joining portion 40 of the other adjacent panel is joined to the joined portion 50 of the one adjacent panel along the direction in which the two adjacent panels are arranged (adjacent direction). This joins two adjacent panels together.
Here, when the panels are joined, the joining part 40 is not bent perpendicularly to the panel body unlike the connecting protrusions 85 of the outer panel 82 constituting the outer dome structure 80, and the surface of the panel body 12 is bent. used in accordance with

Also, one of the two adjacent panels can be joined to the other adjacent panel at each of the four sides of the quadrangle formed by the outer edge of the panel body 12 .

More specifically, for example, the adjacent panels are brought closer together in the adjacent direction while the first side of the panel body 12 of one adjacent panel faces the second side of the panel body 12 of the other adjacent panel. At this time, as shown in FIG. 8, the joint piece 41 protruding from the first side of one adjacent panel approaches the missing area Ra of the second side of the other adjacent panel, and eventually crosses the missing area Ra. It overlaps the joint piece lacking portion 51 in the panel body 12 of the other adjacent panel. Similarly, the joint piece 42 protruding from the second side of the other adjacent panel approaches the missing area Ra of the first side of the one adjacent panel, and eventually crosses the missing area Ra to the panel main body of the one adjacent panel. 12 is overlaid on the joint missing portion 51 .

According to the above procedure, the two adjacent panels are joined so that the first side of one adjacent panel is aligned with the second side of the other adjacent panel by means of respective joining pieces 41, 42, as shown in FIG. spliced. When the adjacent panels are joined together, as shown in FIG. 9, the joint piece 41 of one adjacent panel and the joint piece 42 of the other adjacent panel are adjacent to each other. Also, in the above state, the joint piece 41 of one adjacent panel overlaps the outer surface of the joint piece missing portion 51 of the panel main body 12 of the other adjacent panel. Similarly, the splice strip 42 of the other adjacent panel overlaps the outer surface of the splice missing portion 51 in the panel body 12 of the one adjacent panel.

As described above, the joint pieces 41 and 42 of each of the two adjacent panels approach the joint missing portion 51 and finally overlap and join the joint missing portion 51 . In other words, the joint pieces 41 and 42 of each adjacent panel enter into the portion of the adjacent adjacent panel lacking the joint piece to form a recess and overlap on the outer surface of the joint piece missing portion 51 . Such a state is hereinafter referred to as "a state in which the joining pieces are engaged with each other" for the sake of convenience.

Also, when the joining pieces are engaged with each other, that is, when the adjacent panels are joined together, the joining protrusions 46 provided on the adjacent panels are inserted into the joining holes 52 . Specifically, as shown in FIGS. 8 and 9, the joining projection 46 protruding from the missing region Ra of the first side of one adjacent panel is connected to the panel main body 12 and the joining piece 42 of the other adjacent panel. is inserted into the joint hole 52 formed at the boundary position of the . Similarly, the joining projection 46 protruding from the missing region Ra of the second side of the other adjacent panel is inserted into the joining hole 52 formed at the boundary position between the panel main body 12 and the joining piece 41 of the one adjacent panel. be

By the above procedure, as shown in FIG. 9, the adjacent panels are joined together with the first side of the panel body 12 of one adjacent panel facing the second side of the panel body 12 of the other adjacent panel. can do. In addition, by the same procedure as above, the adjacent panels can be joined together so that the second side of the panel body 12 of one adjacent panel and the first side of the panel body 12 of the other adjacent panel are aligned. can.

Further, for example, in a state in which the third side of the panel body 12 of one adjacent panel faces the fourth side of the panel body 12 of the other adjacent panel, the adjacent panels are brought closer to each other in the adjacent direction. At this time, the joint pieces 43 and 44 protruding from the third side of one adjacent panel approach the missing region Ra of the fourth side of the other adjacent panel, and eventually cross the missing region Ra to the other adjacent panel. It is superimposed on the joining piece missing portion 51 of the panel body 12 . Similarly, the joint piece 45 protruding from the fourth side of the other adjacent panel approaches the missing area Ra of the third side of the one adjacent panel, and eventually crosses the missing area Ra to the panel body of the one adjacent panel. 12 is overlaid on the joint missing portion 51 . That is, the mating strips interlock between two adjacent panels.

According to the above procedure, the two adjacent panels are joined so that the third side of one adjacent panel is aligned with the fourth side of the other adjacent panel by means of respective joining pieces 43-45, as shown in FIG. spliced. When the adjacent panels are joined together, the joint pieces 43 and 44 and the joint piece 45 are adjacent to each other. Specifically, as shown in FIG. 10, a joint piece 45 of one adjacent panel is inserted between two joint pieces 43 and 44 of one adjacent panel. In the above state, the joint pieces 43 and 44 of one adjacent panel overlap the outer surface of the joint missing portion 51 of the panel main body 12 of the other adjacent panel. Similarly, the joint piece 45 of the other adjacent panel overlaps the outer surface of the joint piece missing portion 51 in the panel body 12 of the one adjacent panel.

Further, when the adjacent panels are joined together, the joining projections 46 provided on each adjacent panel are inserted into the joining holes 52 . Specifically, the joining projection 46 protruding from the missing region Ra of the third side of one adjacent panel is a joining hole formed at the boundary position between the panel main body 12 and the joining piece 45 of the other adjacent panel. 52 is inserted. In addition, the joint projection 46 protruding from the missing region Ra of the fourth side of the other adjacent panel is inserted into the joint hole 52 formed at the boundary position between the panel main body 12 and the joint pieces 43 and 44 of the one adjacent panel. inserted.

By the above procedure, as shown in FIG. 10, the adjacent panels are joined together with the third side of the panel body 12 of one adjacent panel facing the fourth side of the panel body 12 of the other adjacent panel. can do. In addition, by the same procedure as above, the adjacent panels can be joined together so that the fourth side of the panel body 12 of one adjacent panel and the third side of the panel body 12 of the other adjacent panel are aligned. can.

As described above, the inner panel 10 switches its posture according to the inner panel 10 to be joined (that is, another inner panel 10 in an adjacent position), thereby appropriately Joinable. This is because, in the inner panel 10, the joining portion 40 and the joined portion 50 are provided in symmetrical positions with respect to the diagonal line CL.
It should be noted that to switch the posture means to switch the side facing the joining partner side among the four sides of the quadrangle formed by the outer edge of the panel body 12 of the inner panel 10. degree or 270 degrees.

From the above effect, it is possible to combine a plurality of inner panels 10 in a dome shape even though the panel shape is the same (that is, one type of shape). That is, the inner dome structure 60 can be composed of one type of inner panel 10 .

In addition, since the inner panel 10 has the joining portion 40, adjacent panels can be joined together by a dry joining method that does not use binding tools such as an adhesive and Insulok. This allows a plurality of inner panels 10 to be easily combined, making the work of assembling the inner dome structure 60 easier.

In addition, due to the meshing of the joining pieces, the joining state of the adjacent panels can be maintained in good condition. In addition, by inserting the joining protrusions 46 into the joining holes 52, the joined state of the adjacent panels can be maintained more firmly. This further facilitates the work of assembling the inner dome structure 60 .

More specifically, the joint portion 40 including the joint pieces 41 to 45 and the joint projections 46 allows the inner dome structure 60 to be assembled while maintaining the state in which the adjacent panels are joined together. Therefore, when assembling the inner dome structure 60, it is not necessary to first assemble the outer dome structure 80 and then hang the inner panel 10 inside the dome to join the inner panels together. That is, even if the outer dome structure 80 has not yet been assembled, the inner dome structure 60 can be assembled independently. At this time, since the joints between the adjacent panels are maintained in good condition, the assembly of the inner dome structure 60 can be proceeded without the need for temporary fixation or reinforcement with tape or the like.

Also, when assembling the inner dome structure 60, the top portion and the side body portion in the inner dome structure 60 can be assembled separately, and finally the top portion can be assembled on the side body portion. Such a procedure improves work efficiency. That is, since it is not necessary to assemble the top portion above the side torso portion after assembling the side torso portion, when assembling the top portion, the work is carried out on the ground or near the floor without using a stepladder or the like. be able to.

In addition, the method of assembling the inner dome structure 60 is different from the method of assembling the outer dome structure 80. Specifically, the adjacent panels are separated by the engagement of the joint pieces and the insertion of the joint projections 46 into the joint holes 52. Join each other. That is, the inner panel 10 does not have a portion that is bent perpendicularly to the panel body 12 at the time of joining the panels, such as the connection protrusion 85, and the thickness of the inner panel 10 is reduced (thinned) by the amount corresponding to the absence of the portion. be able to. Furthermore, since the portion corresponding to the connecting projection 85 does not appear on the inner surface of the inner dome structure 60, the space inside the dome can be expanded, and as a result, the space inside the dome can be used more effectively. can.

The joint pieces 41, 42, 43, and 45 are parallelograms or shapes similar to parallelograms, and their upstream edges are inclined toward the upstream side as they separate from the panel body 12. there is According to such a configuration, the joint pieces 41, 42, 43, and 45 joined to the joint piece lacking portion 51 are separated from the joint piece lacking portion 51 (that is, the joint state with the joint piece lacking portion 51 is released). (moving in the direction of movement) can be suppressed.

Further, on the outer surface of the inner panel 10, a bending line L3 is formed on the outer surface of the panel body 12 along the outer edge of the panel body 12 at the boundary position between the joining pieces 41 to 45 and the panel body 12. In this case, after the joint pieces are engaged with each other, the joint pieces 41 to 45 can be easily bent upward from the bending line L3, so that the joint pieces 41 to 45 and the joint piece lacking portion 51 can be easily joined. be able to.
If the bending line L3 is formed on the inner surface of the panel main body 12, each joint piece should be bent along the surface of the panel main body 12 (specifically, the outer surface of the joint missing portion 51). can be bent starting from As a result, each portion of the surface of the inner dome structure 60 at the time of completion of assembly can be brought closer to a curved surface (spherical surface).

A joint hole 52 is formed at a boundary position between the joint pieces 41 to 45 and the panel main body 12, that is, on the bending line L3. Therefore, when inserting the joint projection 46 into the joint hole 52 , the joint pieces 41 to 45 can be bent outward, so that the joint projection 46 can be easily inserted into the joint hole 52 .

In addition, since the adjacent panels are joined by the engagement of the joining pieces and the insertion of the joining protrusions 46 into the joining holes 52, the assembled inner dome structure 60 has a small gap between the adjacent panels. formation is suppressed. As a result, the inner dome structure 60 can appropriately block outside light leaking into the dome through the joints of the outer dome structure 80 , that is, the gaps between the panels.

In addition, when the joint pieces are engaged with each other, as described above, each joint piece overlaps the outer surface of the joint piece lacking portion 51, so that the force acting on the outer surface of the adjacent panel can be appropriately resisted. can be done.

To make it easier to understand, when the inner dome structure 60 is assembled inside the outer dome structure 80, the weight of the outer dome structure 80 acts on the inner dome structure 60 as an external force. This external force acts inwardly on the inner panel 10 that constitutes the inner dome structure 60 . Here, if the joint pieces engage with each other so that each joint piece slips into the lower side (inside) of the joint piece missing portion 51, when the above-described inward force acts, each joint piece sinks inward, As a result, the joint pieces are likely to be disengaged from each other.

On the other hand, when the joint pieces are engaged with each other so that each joint piece overlaps the outer surface of the joint piece lacking portion 51, even if an inward force is applied, the joint pieces will not sink. Since it is locked by the lacking portion 51, the meshing state of the joining pieces is maintained appropriately. Thereby, the joint strength of the adjacent panels can be improved.

In addition, in a state in which the joint pieces are engaged with each other so that each joint piece overlaps the outer surface of the joint piece lacking portion 51, the inner panel 10 is blown by, for example, a fan installed inside the inner dome structure 60. A force (outward force) may act on the In this case, each joint piece floats outward, and as a result, the engagement between the joint pieces is likely to be released. By arranging the inner dome structure 60 inside the outer dome structure 80, even when an outward force is applied to the inner panel 10, the mating state of the joint pieces is appropriately maintained. be done. As a result, the inner dome structure 60 can further improve the bonding strength of adjacent panels.

Also, in the inner dome structure 60, there is a point where three or four inner panels 10 join together and gather (hereinafter referred to as a gathering point Q), such as the highest point of the dome. The three or four inner panels 10 arranged around the gathering point Q are arranged at regular intervals with the gathering point Q as the center. Specifically, at the gathering point Q where the four inner panels 10 gather, as shown in FIG. 11, the inner panels 10 are arranged at intervals of 90 degrees around the gathering point while rotating their attitudes by 90 degrees. there is In addition, at a gathering point Q where three inner panels 10 gather, the inner panels 10 are arranged at intervals of 120 degrees around the gathering point Q while rotating their attitudes by 120 degrees.

Around the gathering point Q, as shown in FIG. 11, joint pieces (joint pieces 44 in the location shown in FIG. 11) provided for each inner panel 10 arranged around the gathering point Q are arranged at equal intervals. is joined to the joining piece lacking portion 51 at the arrangement position of . According to such a configuration, since the joining pieces are uniformly arranged near each gathering point in the inner dome structure 60, the strength (joining strength) around the gathering point Q can be made uniform. As a result, the bias of the intensity distribution around the gathering point Q is suppressed.

[Method of assembling the inner dome structure to the outer dome structure]
The method of assembling the assembled inner dome structure 60 to the outer dome structure 80 will now be described with reference to FIGS. 12-14.

In this case, as shown in FIG. 12, it is bent so that the projecting direction is horizontal. The horizontally bent joint pieces 41 to 45 are overlaid on the portion of the main body portion of the bottom portion 81 where the outer joint piece 86 does not protrude from the inner edge (that is, the portion lacking the outer joint piece 86). Join with the relevant part. Also, the joint protrusion 46 bent horizontally is inserted into the outer joint hole 88 .

In addition, the width of the portion of the joint protrusion 46 adjacent to the root portion on the tip side thereof is longer than the width of the outer joint hole 88 . In addition, the width dimension in the longitudinal direction of the outer joint hole 88 is set shorter than the longest dimension of the joint protrusion 46 in the width direction. Such a shape of the joint protrusion 46 functions as a retaining structure that prevents the joint protrusion 46 from coming off from the outer joint hole 88 .

By joining the lower panel to the bottom portion 81 in the above procedure, the inner dome structure 60 can be easily and reliably assembled to the outer dome structure 80 without using binding tools such as tapes or Insulok. can.
