(First embodiment)
FIG. 1 is a perspective view showing an appearance of an assembly structure 1 according to the first embodiment. FIG. 2 is an exploded perspective view of the assembly structure 1 in the first embodiment.
The assembly structure 1 is used, for example, as a partition for partitioning a space in an event hall or the like, or as a simple shooting booth in an event venue, a press conference hall, or the like. As will be described later, the assembled structure 1 can be stored and transported in a compact size by removing the fixtures and folding each panel. Moreover, the assembly structure 1 can be installed as an original three-dimensional structure by attaching each of the folded parts to a developed state and attaching a fixture.

<Overall configuration of assembly structure 1>
As shown in FIG. 1, the assembly structure 1 of the first embodiment includes a main panel 10, a pair of side panels 20, and a plurality (four in this embodiment) of fixtures 30.
The main panel 10 is a plate-like member that is a main part of the assembly structure 1. In the following description, the front side (Z1 side) is referred to as the front side or the front side, and the back side (Z2 side) is referred to as the back side or the back side in a state where the assembly structure 1 is arranged as shown in FIG. Depending on the usage pattern of the assembly structure 1, the near side may be the back side and the far side may be the front side. That is, the descriptions of “front”, “front side”, “rear side”, and “rear side” in each embodiment are for convenience and may be replaced as appropriate.

  For example, when the assembly structure 1 is used as a photography booth for a press conference, the front side of the main panel 10 is a so-called appeal surface, and a design such as a sponsor company name (company logo) is printed. Moreover, when using the assembly structure 1 as a partition, the main panel 10 becomes a wall material which partitions space. In that case, both sides (front side and back side) of the main panel 10 are plain or printed with a pattern, a picture, or the like. As will be described later, the main panel 10 is configured to be deformable between a folded state and a flattened unfolded state.

  The side panel 20 is a plate-like member that supports both sides of the main panel 10 in the width direction (X direction). As shown in FIG. 1, the pair of side panels 20 are respectively disposed on both sides of the main panel 10 in the width direction. As shown in FIG. 2, the side panel 20 has an opening 20 a (described later) at a position facing the side 10 e of the main panel 10. The side panel 20 is basically plain, but a pattern, a pattern, or the like may be printed thereon. As will be described later, the side panel 20 is configured to be deformable between a folded state and a flattened unfolded state.

  The fixture 30 is a member that fixes the main panel 10 and the side panel 20. The fixing tool 30 is engaged with the main panel 10 by being inserted from the opening 20a of the side panel 20 in a state where the side panel 20 is disposed at a position facing the side 10e of the main panel 10, The main panel 10 and the side panel 20 are fixed integrally.

This is to prevent the entire fixture 30 from being buried inside the opening 20a (20b) when the fixture 30 is inserted into the opening 20a (20b) of the side panel 20. Moreover, the dimension h1 of the vertical direction (Y direction) of the support plate 31 should just be more than the dimension h3 of the vertical direction of the opening part 20a (20b). This is to prevent the engaging portion 32 and a part of the opening 20a (20b) from being exposed from the side surface of the side panel 20 when the fixture 30 is inserted into the opening 20a (20b) of the side panel 20. In FIG. 7A, the outline of the opening 20a (20b) provided in the side panel 20 is indicated by an imaginary line (two-dot chain line).

  The engaging portion 32 is a portion that engages with the main panel 10. As shown in FIG. 7B, the engaging portion 32 is formed to be substantially U-shaped when viewed from the vertical direction (Y direction). Further, as shown in FIG. 7A, the engaging portion 32 extends along the vertical direction (Y direction). The dimension h2 in the vertical direction (Y direction) of the engaging portion 32 is desirably the same as or slightly shorter than the dimension h3 in the vertical direction of the opening 20a (20b). When the fixture 30 is inserted into the opening 20a (20b) of the side panel 20 and engaged with the main panel 10, the engaging portion 32 is located in the longitudinal direction (Y direction) inside the opening 20a (20b). This is to prevent wobbling.

As shown in FIGS. 7A and 7B, the engaging portion 32 includes a base portion 32a and a clamp portion 32b.
The base portion 32 a is a portion that is joined to the support plate 31. When the support plate 31 and the engaging portion 32 are formed of a resin material, the support plate 31 and the engaging portion 32 (base portion 32a) are joined by welding, adhesion, or the like, for example. It is desirable that the lateral dimension (X direction) W2 of the base 32a is the same as or slightly shorter than the lateral dimension W3 of the opening 20a (20b). When the fixture 30 is inserted into the opening 20a (20b) of the side panel 20 and engaged with the main panel 10, the engaging portion 32 is laterally (X direction) inside the opening 20a (20b). This is to prevent wobbling. In addition, the support plate 31 and the engaging part 32 may be integrally formed.

  The clamp portion 32 b is a portion that engages with the main panel 10. As shown in FIG. 7B, the clamp portion 32b has a pair of clamp pieces 321b extending from the base portion 32a to the Z2 side. The pair of clamp pieces 321b are separated in the vicinity of the base portion 32a, and are formed so as to gradually approach (or contact) toward the distal end side (Z2 side). According to this, when the main panel 10 is inserted between the pair of clamp pieces 321b (clamp portion 32b), a restoring force is generated in which the pair of clamp pieces 321b tries to return to the original position (shape). This acts as a biasing force in the direction of the arrow in the figure. The ends of the pair of clamp pieces 321b are separated from each other so as to be substantially V-shaped. This is because the main panel 10 is easily inserted between the pair of clamp pieces 321b.

  The support plate 31 and the engaging portion 32 are formed of a light-transmitting resin material such as PET (polyethylene terephthalate), acrylic resin, PVC (vinyl chloride resin), and the like. The support plate 31 and the engaging portion 32 are particularly preferably formed of a transparent member. By forming the fixture 30 with a transparent member, it is possible to prevent the design (sponsor company name, etc.) printed on the appealing surface of the main panel 10 from being covered with the engaging portion 32 and becoming invisible. Further, the support plate 31 exposed on the outer surface of the side panel 20 can be made inconspicuous.

  In addition, when the appeal surface of the main panel 10 is plain, the fixture 30 may not be formed of a transparent member or may be colored with the same color as the appeal surface. In that case, the support plate 31 and the engaging portion 32 may be formed of a metal material such as aluminum or iron, for example. Moreover, it is good also as a structure which combined the resin material and metal material which were mentioned above. Specifically, an example in which the support plate 31 is formed of a metal material and the engaging portion 32 is formed of a resin material can be given.

Next, attachment of the fixture 30 will be described.
FIG. 8 is a conceptual diagram showing an attachment state of the fixture 30. FIG. 8A is a conceptual diagram showing a state before the fixture 30 is inserted into the side panel 20. FIG. 8B is a conceptual diagram showing a state after the fixing tool 30 is inserted into the side panel 20. Hereinafter, the case where the fixing tool 30 is inserted into the opening 20a on the upper side (Y1 side) of the side panel 20 will be described as an example. The same effect occurs when the fixture 30 is inserted into the opening 20b on the lower side (Y2 side) of the side panel 20.

  As shown in FIG. 8A, the fixture 30 is inserted from the opening 20a of the side panel 20 in a state where the side 10e of the main panel 10 and the opening 20a of the side panel 20 are in contact with each other. Is done. When the fixture 30 is inserted from the opening 20a of the side panel 20, the tips of the pair of clamp pieces 321b (clamp portion 32b) of the fixture 30 abut against the side 10e of the first panel 101 (main panel 10). In contact with each other, they are spread out in directions away from each other (left and right in the figure). When the fixture 30 is further pushed into the side panel 20, the pair of clamp pieces 321 b protrude from the gap S between the main panel 10 and the opening 20 a of the side panel 20.

  Then, as shown in FIG. 8B, when the support plate 31 of the fixture 30 is inserted to a position where it contacts the front side (X1 side) of the side panel 20, the pair of clamp pieces 321b is further expanded. , Engage with the first panel 101 (main panel 10). Thereby, the 1st panel 101 is hold | maintained with the urging | biasing force of a pair of clamp piece 321b (fixing tool 30). Further, the fixture 30 is engaged with the main panel 10 with the side panel 20 interposed therebetween. The main panel 10 and the side panel 20 are integrally fixed by a fixing tool 30.

On the other hand, when the support plate 31 of the fixture 30 is inserted to a position where it contacts the front side of the side panel 20, as shown in FIG. 8B, the base portion 32a of the engagement portion 32 (fixture 30) It fits in the opening 20a of the panel 20, and the movement to a horizontal direction and a vertical direction (X direction and Y direction shown in FIG. 7) is controlled. When the fixing tool 30 is inserted into each of the openings 20a and 20b of the main panel 10, the main panel 10 is fixed by the fixing tool 30 at two places above and below with the bent portion 13h interposed therebetween as shown in FIG. . Thereby, as shown to FIG. 4 (B), it can suppress that the main panel 10 of an unfolded state deform | transforms into a folded state.
The fixture 30 is detachably engaged with the main panel 10. Therefore, if the fixing tool 30 is pulled out from the opening 20a of the side panel 20, the engagement between the main panel 10 and the side panel 20 is released, and the main panel 10 and the side panel 20 can be disassembled.

<Installation method of assembly structure 1>
Next, the installation method of the assembly structure 1 in 1st Embodiment is demonstrated.
FIG. 9 is a conceptual diagram showing a method for installing the assembly structure 1 in the first embodiment.

Next, as shown in FIG. 9B, the left side (X1 side) side 10e of the main panel 10 and the openings 20a and 20b of the one side panel 20 are arranged so as to contact each other. Note that FIG. 9B shows a positional relationship when the main panel 10 and the one side panel 20 are arranged, and both are separated from each other in the drawing.

  The side panel 20 is basically disposed so that the inner (X2 side) surface is in contact with the main panel 10, but may be disposed so that the outer (X1 side) surface is in contact with the main panel 10 ( The same applies to other embodiments). Subsequently, the two fixing tools 30 are inserted into the openings 20a and 20b of the one side panel 20, respectively. Thereby, the left side 10e of the main panel 10 and the one side panel 20 are integrally fixed.

Next, as shown in FIG. 9C, the side 10 e on the right side (X2 side) of the main panel 10 and the openings 20 a and 20 b of the other side panel 20 are in contact with each other. Note that FIG. 9C shows the positional relationship when the main panel 10 and the other side panel 20 are arranged, and both are separated in the drawing. Subsequently, the fixture 30 is inserted into the openings 20a and 20b of the other side panel 20, respectively. Thereby, the right side 10e of the main panel 10 and the other side panel 20 are integrally fixed.
By assembling in the above procedure, the assembly structure 1 of the first embodiment can be installed (see FIG. 1). Note that the side panel 20 may be attached to the main panel 10 in order from the right side (X2 side) to the left side (X1 side) of the main panel 10.

In the assembly structure 2 of the second embodiment, other configurations are the same as those of the first embodiment. Therefore, in the description of the second embodiment and the drawings, the same members as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment or the reference numerals such as A at the end, and redundant description is omitted. .

  FIG. 10 is a perspective view showing an appearance of the assembly structure 2 in the second embodiment. FIG. 11 is an exploded perspective view of the assembly structure 2. FIG. 12 is a perspective view showing the configuration of the main panel 10A. FIG. 13 is a perspective view showing the configuration of the main panel 10B.

FIG. 15A is a conceptual diagram showing a state before the main panels 10A to 10C are joined. FIG. 15B is a conceptual diagram showing a state after the main panels 10A to 10C are joined.

<Overall configuration of assembly structure 2>
As shown in FIG. 10, the assembly structure 2 of the second embodiment includes main panels 10A to 10C, a pair of side panels 20A, and a plurality (six in this embodiment) of fixtures 30. Since the configuration of the fixture 30 used in the second embodiment is the same as that of the first embodiment, description thereof is omitted.

  As shown in FIG. 11, the assembly structure 2 according to the second embodiment includes main panels 10A, 10B, and 10C (hereinafter also collectively referred to as “main panel 10”) having different configurations. The main panel 10 </ b> A is a panel arranged at the left end (X1 side) of the assembly structure 2. The main panel 10 </ b> B is a panel disposed on the right side (X2 side) end of the assembly structure 2. The main panel 10C is a panel arranged between the main panels 10A and 10B in the assembly structure 2. The main panel 10 according to the second embodiment is different from the main panel 10 according to the first embodiment in that the main panel 10 includes a joint described later. Hereinafter, the main panels 10A, 10B, and 10C will be described in this order.

<Configuration of main panel 10A>
As shown in FIG. 12, the main panel 10 </ b> A includes a first core material 11, a second core material 12, a front paperboard 13, a first back paperboard 14, and a second back paperboard 15. In the main panel 10A of the second embodiment, the configuration of each part excluding the first core material 11 and the second core material 12 is the same as that of the first embodiment, and thus the description thereof is omitted.

  The main panel 10A has recesses 11a and 12a on the side 10e on the side not in contact with the side panel 20A (X2 side) as a joint with the adjacent main panel 10C (not shown). The recess 11a is a rectangular recess provided on the side 10e on the X2 side in the first core member 11. The recess 12a is a rectangular recess provided in the X2 side 10e in the second core member 12. As shown in FIG. 15B, convex portions 11b and 12b (described later) of the adjacent main panel 10C are fitted into the concave portions 11a and 12a, respectively. In addition, as shown in FIG. 12, the recessed parts 11a and 12a are provided only in the 1st core material 11 and the 2nd core material 12, and are not provided in the paperboard. Therefore, when each part is bonded and it is set as the main panel 10A, the recessed parts 11a and 12a become a bag-shaped space.

  As shown in FIG. 15A, the recess length L1 of the recesses 11a and 12a in the main panel 10A is set according to the lengths L2 and L3 from which the projections 11b and 12b (described later) of the main panel 10C protrude. The In the present embodiment, the recess length L1 of the concave portions 11a and 12a is equal to the length L2 from which the convex portion 11b protrudes. In addition, you may change the hollow length L1 of the recessed parts 11a and 12a according to length L2 and L3 which the convex parts 11b and 12b protrude.

<Configuration of main panel 10B>
As shown in FIG. 13, the main panel 10 </ b> B includes a first core material 11, a second core material 12, a front paperboard 13, a first back paperboard 14, and a second back paperboard 15. In the main panel 10B, the configuration of each part excluding the first core material 11 and the second core material 12 is the same as that of the first embodiment, and thus the description thereof is omitted.

  The main panel 10B has convex portions 11b and 12b on the side 10e on the side not in contact with the side panel 20A (X1 side) as a joint with the adjacent main panel 10C (not shown). The convex portion 11 b is a substantially rectangular protrusion provided on the side edge 10 e on the X1 side in the first core material 11. The convex portion 12 b is a substantially rectangular protrusion provided on the side 10 e on the X1 side in the second core member 12. The tips of the convex portions 11b and 12b are formed in a triangular shape. The convex portions 11b and 12b are fitted into the concave portions 11a and 12a of the main panel 10C (described later), respectively.

  As shown in FIG. 15A, the convex portions 11b and 12b of the main panel 10B are provided at the same positions as the concave portions 11a and 12a of the main panel 10C (10A) in the height direction (Y direction). In the main panel 10B, the length L3 that the convex portion 12b of the second panel 102 protrudes from the side 10e is set shorter than the length L2 that the convex portion 11b of the first panel 101 protrudes from the side 10e. ing. The same applies to convex portions 11b and 12b of the main panel 10C described later.

  When the length L2 of the convex portion 11b of the first panel 101 is equal to the length L3 of the convex portion 12b of the second panel 102, when the main panel 10B is joined to the main panel 10C, the vertical direction of each panel ( In the (Y direction), since each convex part and concave part must be joined simultaneously, the operation becomes difficult.

  However, if the length L3 of the convex portion 12b is shorter than the length L2 of the convex portion 11b as in the main panel 10 of the present embodiment, the respective convex portions and concave portions are separately fitted in the vertical direction of each panel. Can be included. That is, when joining the main panel 10B to the main panel 10C, the operator first fits the convex portion 11b on the upper side (Y1 side) of the main panel 10B and the concave portion 11a on the upper side (Y1 side) of the main panel 10C, Next, the lower (Y2 side) convex portion 12b of the main panel 10B and the lower (Y2 side) concave portion 12a of the main panel 10C may be fitted. The same is true when a main panel 10C described later is joined to the main panel 10A.

  When fitting the upper convex portion 11b of the main panel 10B and the upper concave portion 11a of the main panel 10C, the lower convex portion 12b of the main panel 10B and the lower concave portion 12a of the main panel 10C are separated from each other. Therefore, the operator does not need to consider the positional deviation between the lower convex portion 12b and the concave portion 12a. Therefore, the operator can easily fit the convex portion 11b on the upper side of the main panel 10B and the concave portion 11a on the upper side of the main panel 10C.

  Next, the work inserts the lower convex portion 12b of the main panel 10B and the lower concave portion 12a of the main panel 10C. At this time, since the upper convex portion 11b of the main panel 10B and the lower concave portion 11a of the main panel 10C are already fitted, the operator can shift the positional deviation between the upper convex portion 11b and the concave portion 11a. There is no need to consider. Therefore, the operator can easily fit the lower convex portion 12b of the main panel 10B and the lower concave portion 12a of the main panel 10C. Thus, the operator first fits the upper convex portion 11b of the main panel 10B and the upper concave portion 11a of the main panel 10C, and then the lower convex portion 12b of the main panel 10B and the lower portion of the main panel 10C. By fitting the recess 12a on the side, both panels can be easily joined.

<Configuration of main panel 10C>
As shown in FIG. 14, the main panel 10 </ b> C includes a first core material 11, a second core material 12, a front paperboard 13, a first back paperboard 14, and a second back paperboard 15. In the main panel 10C, the configuration of each part excluding the first core material 11 and the second core material 12 is the same as that in the first embodiment, and thus the description thereof is omitted.

  The main panel 10C includes convex portions 11b and 12b on the side 10e on the left side (X1 side) in the width direction as a joint with the adjacent main panel 10A (not shown). The convex portion 11 b is a substantially rectangular protrusion provided on the side edge 10 e on the X1 side in the first core material 11. The convex part 12b is a substantially rectangular protrusion provided on the side 10e on the X1 side in the second core member 12 of the main panel 10C. The tips of the convex portions 11b and 12b are formed in a triangular shape. The convex portions 11b and 12b are fitted into the concave portions 11a and 12a of the main panel 10A, respectively. Since the shape, position, and the like of the convex portions 11b and 12b in the main panel 10C are the same as those of the convex portions 11b and 12b (see FIG. 13) of the main panel 10B, description thereof is omitted.

  On the other hand, the main panel 10C has recesses 11a and 12a on the right side (X2 side) side 10e in the width direction as joints with the adjacent main panel 10B (not shown). The recess 11a is a rectangular recess provided on the side 10e on the X2 side in the first core member 11. The recess 12a is a rectangular recess provided in the X2 side 10e in the second core member 12. The convex portions 11b and 12b of the main panel 10B are fitted into the concave portions 11a and 12a, respectively. Since the shapes, positions, and the like of the recesses 11a and 12a in the main panel 10C are the same as those of the recesses 11a and 12a (see FIG. 12) of the main panel 10A, description thereof is omitted.

<Configuration of side panel 20A>
Next, the side panel 20A will be described. FIG. 16 is an exploded perspective view of the side panel 20A.
The side panel 20A of the second embodiment is different from the side panel 20 of the first embodiment in that it has three openings 20a to 20c (see FIG. 11) in the height direction (Y direction). Since the pair of side panels 20A have the same configuration, the configuration will be described here taking the side panel 20A disposed on the X1 side of the main panel 10 as an example.

  In the description of the side panel 20A, as in FIG. 5 (side panel 20), the X1 side is defined as the outside, and the X2 side is defined as the inside, with the side panel 20A being arranged as illustrated in FIG. Incidentally, in the side panel 20A arranged on the X2 side (see FIG. 10) of the main panel 10, the X2 side is the outside and the X2 side is the inside.

  As shown in FIG. 16, the side panel 20 </ b> A includes a first core member 21, a second core member 22, an outer paperboard 23, a first inner paperboard 24, and a second inner paperboard 25. Since the basic shape, size, material, and the like of each part constituting the side panel 20A are the same as those in the first embodiment, description thereof is omitted.

The first core material 21 has a core material opening 21a and a first core material recess 221c. The first core material recess 221c is a rectangular recess that forms a core material opening 22c together with a second core material recess 222c (described later) of the second core material 22 when the side panel 20A is in an unfolded state. The shape and size of the core material opening 22c (see FIG. 11) are the same as the core material openings 22a and 22b. The core material opening 22c is divided into a first core material recess 221c and a second core material recess 222c when the side panel 20A is folded.
The second core member 22 has a core member opening 22b and a second core member recess 222c. The second core material recess 222c is a rectangular recess that forms the core material opening 22c together with the first core material recess 221c of the first core material 21 described above when the side panel 20A is in the unfolded state.

  The outer paperboard 23 is a sheet material provided on the front side (X1 side) of the side panel 20A. The outer paperboard 23 has paperboard openings 23a, 23b, and 23c on the upper side (Y1 side), the lower side (Y2 side), and the middle thereof, respectively. The shape and size of the paperboard openings 23a, 23b, and 23c when viewed from the X direction are the same as the core material openings 21a, 22b, and 22c.

  The paperboard openings 23a, 23b, and 23c are arranged when the first core material 21 and the second core material 22 are arranged side by side in the height direction (Y direction), and the outer paperboard 23 is attached to the front side (X1 side). Are provided at positions corresponding to the core material openings 21a, 22b, and 22c (first core material recess 221c + second core material recess 222c), respectively. The center position in the height direction (Y direction) of the paperboard opening 23c coincides with the position of the side panel bent portion 23h. Therefore, the side panel 20A of the second embodiment is folded in two at the position of the opening 20c by rotating the first side panel 201 outward (X1 side) around the side panel bent portion 23h. Can do.

  The first inner paperboard 24 is a sheet material provided on the back side (X2 side) of the first core material 21. The first inner paperboard 24 has a paperboard opening 24a and a first paperboard recess 241c. The first paperboard recess 241c is a rectangular cutout that forms a paperboard opening 24c together with a second paperboard recess 242c (described later) of the second inner paperboard 25 when the side panel 20A is in an unfolded state. The shape and size of the paperboard opening 24 c when viewed from the X direction are the same as the paperboard opening 23 c of the outer paperboard 23.

The second inner paperboard 25 is a sheet material provided on the back side (X2 side) of the second core material 22. The second inner paperboard 25 has a paperboard opening 25b and a second paperboard recess 242c. The second paperboard recess 242c is a rectangular cutout that forms a paperboard opening 24c together with the first paperboard recess 241c of the first inner paperboard 24 described above when the side panel 20A is in the unfolded state.
In the side panel 20A of the second embodiment, the outer paperboard 23 is attached to the outside (X1 side) of the first core material 21 and the second core material 22 arranged side by side in the height direction (Y direction), and the inside (X2 side) ), The first inner paperboard 24 and the second inner paperboard 25 are attached.

<Installation method of assembly structure 2>
Next, the installation method of the assembly structure 2 in 2nd Embodiment is demonstrated.
FIG.17 and FIG.18 is a conceptual diagram which shows the installation method of the assembly structure 2 in 2nd Embodiment.

  First, as shown in FIG. 17A, the folded main panel 10 (10A to 10C) and the side panel 20A are opened in the direction of the arrow to be in an unfolded state. In FIG. 17A, only the main panel 10A is shown, but the main panels 10B and 10C are also in the unfolded state. In FIG. 17A, only one side panel 20A is shown, but two side panels 20A are used.

  Next, as shown in FIG. 17B, the left side (X1 side) side 10e of the main panel 10A and the openings 20a, 20b, and 20c of the one side panel 20A are disposed so as to contact each other. Note that FIG. 17B shows a positional relationship when the main panel 10A and the one side panel 20A are arranged, and both are separated in the drawing.

  Subsequently, the three fixing tools 30 are respectively inserted into the openings 20a, 20b and 20c of the one side panel 20A. Thereby, the left side 10e of the main panel 10A and the one side panel 20A are fixed integrally. In one side panel 20A, the fixture 30 inserted into the opening 20c collectively holds the bent portion 13h of the main panel 10A and the left side (X1 side) of the first panel 101 and the second panel 102.

Note that FIG. 22C shows a positional relationship when the main panel 10 and the other side panel 20B are arranged, and both are separated in the drawing.

Subsequently, the fixture 30 is inserted into the opening 20 c of the other side panel 20. Thereby, the right side 10e of the main panel 10 and the other side panel 20B are fixed integrally. In the other side panel 20B, the fixture 30 inserted into the opening 20c collectively holds the bent portion 13h of the main panel 10, the right side (X2 side) of the first panel 101 and the second panel 102.
By assembling in the above procedure, the assembly structure 3 of the third embodiment can be installed (see FIG. 19). Note that the side panel 20B may be attached to the main panel 10 in order from the right side (X2 side) to the left side (X1 side) of the main panel 10.

Similar to the first embodiment, the assembly structure 3 of the third embodiment described above is excellent in stability as a structure and can be easily assembled and folded.
Since the fixture 30 of the third embodiment has a long length in the vertical direction (Y direction), the bent portion 13h of the main panel 10, the right side and the left side of the first panel 101 and the second panel 102 can be held together. Therefore, the assembled structure 3 according to the third embodiment has a simple configuration in which one fixing tool 30 is provided on each of the left and right in the width direction (X direction), but the main panel 10 in the unfolded state is deformed into a folded state. Can be suppressed. Moreover, since the assembly structure 3 of 3rd Embodiment is the structure which provides the fixing tool 30 on the right and left of the width direction of the main panel 10, respectively, an assembly and folding can be performed more simply and in a short time.

  In the third embodiment, a configuration in which a plurality of main panels 10 are provided may be used. In that case, however, a plurality of fixtures 30 are provided on the left and right in the width direction of the main panel 10 as in the second embodiment. It is desirable to provide a configuration. However, in the case where both the width direction (X direction) and the height direction (Y direction) of the main panel 10 are short, or when the main panel 10 is lightweight, even if there are a plurality of main panels 10, As in the third embodiment, one fixing tool 30 may be provided on each of the left and right sides of the main panel 10 in the width direction.

FIG. 23 is a perspective view showing an appearance of the assembly structure 4 in a modified form. The assembly structure 4 shown in FIG. 23 is configured as a face panel installed in a sightseeing spot, an event venue, or the like. In the assembly structure 4 of the present embodiment, a pattern (not shown) imitating a person, an anime character, or the like is printed on the front side (Z1) of the main panel 10, and the user can match the pattern. An opening 10a for fitting a face is provided. When the number of the main panel 10 is one as in the first or third embodiment, the opening 10a may be provided anywhere on the first panel 101 and the second panel 102. On the other hand, when the main panel 10 is composed of a plurality of panels as in the second embodiment, the opening 10a can be provided at a position where it does not interfere with the joint (concave portion or convex portion). In any case, the opening 10a may straddle the bent portion 13h or may straddle the adjacent main panel 10.

  In the first to third embodiments, the main panel 10 may be composed of only the core material without forming the first panel 101 and the second panel 102 in a laminated structure. In that case, what is necessary is just to connect one edge part of the side edge which the 1st core material 11 and the 2nd core material 12 mutually oppose as a bending part with a tape-shaped member.

For example, in the first embodiment, the vertical dimension of the fixture 30 provided on the lower side (Y2 side) of the side panel 20 may be larger than that of the fixture 30 provided on the upper side (Y1 side). In this case, the assembly structure 1 can be further stabilized. In the second embodiment, the vertical dimension of the fixture 30 may be increased stepwise from the upper side (Y1 side) to the lower side (Y2 side) of the side panel 20A.

  In 2nd Embodiment, the front-end | tip of convex part 11b, 12b (joining part) is not restricted to a triangle, For example, a semicircle, trapezoid, etc. may be sufficient. Further, the shape of the concave portions 11a and 12a (joint portions) is not limited to a rectangular shape, and may be any shape as long as the convex portions 11b and 12b can be accommodated. Further, three or more convex portions and concave portions may be provided on both sides of the main panel 10 in the width direction (X direction). Further, in the second embodiment, the example in which only the convex portion or the concave portion is provided on one side 10e of the main panel 10 has been described, but the convex portion and the concave portion may be alternately provided.

  In the main panels 10B and 10C of the second embodiment, the length L2 that the convex portion 11b of the first panel 101 protrudes from the side 10e, and the length L3 that the convex portion 12b of the second panel 102 protrudes from the side 10e. It may be set shorter. In addition, when the dimension in the height direction (Y direction) of the entire main panel 10 including the main panels 10B and 10C is short, a length L2 at which the convex portion 11b of the first panel 101 protrudes from the side 10e, It is good also as length L3 which the convex part 12b of the 2 panel 102 protrudes from the side 10e.
