Description

[Technical Field]

[0001] The present invention relates to a panel joining method for joining a plurality of panels using a joining member. [Background technology]

[0002] Generally, battens are used to join form panels used in construction when pouring concrete (Patent Documents 1 to 3). Although battens are sometimes used to increase the rigidity of formwork panels, when the rigidity of formwork panels is ensured by fastening them with pipe material, the battens only function to temporarily fix the formwork panels. Not only is the nailing required to attach the battens a significant burden, but the bulky formwork panels with battens attached make them difficult to transport and store. Furthermore, removing the nails is also a significant burden, meaning that most of the battens end up as waste after construction. Patent Documents 4 and 5 propose joining members for connecting form panels. [Prior art documents] [Patent documents]

[Example]

[0031] An embodiment of the panel joining method according to the present invention will now be described. The panel joining method according to the present invention is used to form formwork panels used in construction when pouring concrete, partition panels for dividing spaces, or wall or ceiling panels for temporary buildings. In the following examples, we will explain formwork panels used in construction when pouring concrete.

[0032] 1 and 2 are side views of the main part of a structure in a construction state showing a panel joining method according to an embodiment of the present invention, and FIGS. 3 to 5 are elevation views of the same structure. The formwork panel according to this embodiment is a panel 10 used in construction when pouring concrete, and is used by joining adjacent panels 10 together using joining members 20 instead of crosspieces.

[0033] As shown in Figure 1, in the construction of formwork for a concrete structure, a pair of walls 10a and 10b are erected on a foundation 1, and concrete is poured into a space 2 between the inner surface of wall 10a and the inner surface of wall 10b. In the beam section, the wall body 10c is supported by a beam support member 3, and the beam support member 3 is held by a pipe support 4. A fastening member 5 is attached to the pair of wall bodies 10a, 10b to maintain a constant distance between the pair of wall bodies 10a, 10b. The fastening member 5 is composed of a separator 5a, a pair of cones 5b, a pair of fastening member bodies 5c, and a pair of washers 5d. The walls 10a, 10b, and 10c are formed by joining multiple panels 10. Crosspieces are generally used to join the panels 10. Crosspieces are sometimes used to increase the rigidity of the panels 10, but in this embodiment, vertical pipe members 6a are placed at predetermined intervals on the outer surfaces of the panels 10 of the wall bodies 10a and 10b, and these vertical pipe members 6a are fastened with horizontal pipe members 6b to ensure the rigidity of the panels 10. The pipe members 6 support the load applied to the panels 10 when concrete is poured. Figure 1 shows the joining members 20 as joining member 20B, which joins the inner angle of the joint between two panels 10, joining member 20C, which joins the outer angle of the joint between the beam bottom projection angles, and joining member 20D, which joins the two panels 10 so that they are on the same plane.

[0034] 2 and 3 show the connecting member 20D, as well as a foot fixing member 50 for fixing the panel 10 to the batten 7 on the base 1, a holding member 60 for fixing the vertical pipe material 6a, and a guide member 70.

[0035] In FIG. 4, the joining member 20D and the spring holder 30 are shown. A first groove-shaped recess 11a is formed on the first panel outer surface 11s of the first panel 11 shown in Figure 4, and a second groove-shaped recess 12a is formed on the second panel outer surface 12s of the second panel 12 that is joined adjacent to the first panel 11. The first panel outer surface 11s and the second panel outer surface 12s are flat surfaces without protrusions for forming the first groove-shaped recess 11a or the second groove-shaped recess 12a. Therefore, the first groove-shaped recess 11a is formed at a position lower than the first panel outer surface 11s, and the second groove-shaped recess 12a is formed at a position lower than the second panel outer surface 12s, so that when the first panel 11 and the second panel 12 are stacked, they can be stacked with a height equal to the panel thickness.

[0036] In Figure 4, the joining member 20D is shown attached by engaging with a first groove-shaped recess 11a formed in the lower part of the first panel 11 and a second groove-shaped recess 12a formed in the upper part of the second panel 12. When the first panel 11 and the second panel 12 are arranged horizontally, the joining member 20 is attached by engaging with a first groove-shaped recess 11a formed on the side of the first panel 11 and a second groove-shaped recess 12a formed on the side of the second panel 12. The first groove-shaped recesses 11a are formed along the side surfaces of the first panel 11 at the top, bottom, and both sides of the first panel 11, and are preferably formed continuously from one end side surface of the first panel 11 to the other end side surface, but the first groove-shaped recesses 11a may also be formed partially. Furthermore, as shown in Fig. 4, it is preferable to form a plurality of first groove-shaped recesses 11a at appropriate intervals, for example, between the top and bottom. The second groove-shaped recesses 12a are formed along the side surfaces of the second panel 12 at the top, bottom, and both sides of the second panel 12. They are preferably formed continuously from one end side surface of the second panel 12 to the other end side surface of the second panel 12, but the first groove-shaped recesses 11a may be formed partially. Furthermore, as shown in Fig. 4, it is preferable to form a plurality of second groove-shaped recesses 12a at appropriate intervals, for example, between the top and bottom. Although FIG. 4 shows first panel 11 and second panel 12 as having the same shape, first panel 11 and second panel 12 may have different shapes and sizes. By forming the first groove-shaped recess 11a along the four side surfaces of the first panel 11 and the second groove-shaped recess 12a along the four side surfaces of the second panel 12, multiple first panels 11 and second panels 12 can be assembled in both the left-right and vertical directions.

[0037] Figure 5 shows the connecting members 20 as connecting member 20A, which is placed at the outer corner of the joint between two panels 10, connecting member 20B, which is placed at the inner corner of the joint between two panels 10, and connecting member 20D, which is placed so that the two panels 10 are on the same plane, as well as a foot fixing device 50 that fixes the panel 10 to the shim 7 on the base 1 and a clamping member 60 that fixes the vertical pipe material 6a. When the joining member 20A is positioned at the outer corner of the joint between the first panel 11 and the second panel 12, the first panel 11 and the second panel 12 are butted together perpendicularly so that the first groove-shaped recess 11a and the second groove-shaped recess 12a are positioned on the surface of the outer corner. When the joining member 20B is positioned at the inner angle of the joint between the first panel 11 and the second panel 12, the first panel 11 and the second panel 12 are butted together perpendicularly so that the first groove-shaped recess 11a and the second groove-shaped recess 12a are positioned on the surface of the inner angle. In this way, by using joining members 20A and 20B, first panel 11 and second panel 12 can be assembled so as to be perpendicular to each other.

[0038] Figure 6 is a structural diagram showing an example of a joining member used in the panel joining method of the present invention, where Figure 6(a) shows the member attached to the panel, Figure 6(b) shows the member with the first ridge-shaped protrusion and the second ridge-shaped protrusion separated, and Figure 6(c) shows the member with the first ridge-shaped protrusion and the second ridge-shaped protrusion close to each other. The joining member 20A according to this embodiment is disposed at the outer corner where the first panel 11 and the second panel 12 join.

[0039] The joining member 20A has a one-side joining member 21 that forms a first ridge-shaped protrusion 21a, an other-side joining member 22 that forms a second ridge-shaped protrusion 22a, and a displacement member 23 that is arranged in a sliding space 21b formed in the one-side joining member 21. A first groove-shaped recess 11a that engages with the first ridge-shaped protrusion 21a is formed in the first panel 11, and a second groove-shaped recess 12a that engages with the second ridge-shaped protrusion 22a is formed in the second panel 12. It is preferable that the first groove-shaped recess 11a and the second groove-shaped recess 12a have inclined sides at least on the outer peripheral side of the panel 10, and that the bottom surfaces of the first groove-shaped recess 11a and the second groove-shaped recess 12a are wider than the opening surfaces.

[0040] FIG. 7 is an exploded perspective view of the joining member shown in FIG. The joining member 21 on one side holds a first pin 21c, and the joining member 22 on the other side holds a second pin 22c. A first groove 23a and a second groove 23b are formed in the displacement member 23. The first groove 23a is formed parallel to the sliding direction, and the second groove 23b is formed inclined relative to the sliding direction. The first pin 21c is disposed in the first groove 23a, and the second pin 22c is disposed in the second groove 23b. The sliding range of the displacement member 23 is restricted by the first pin 21c, and the displacement member 23 is prevented from falling off from the one-side joining member 21. Since the second pin 22c moves along the second groove 23b, by displacing the displacement member 23 relative to the sliding space 21b, the other-side joining member 22 is displaced relative to the one-side joining member 21, and the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a move closer to or farther apart from each other. It is preferable that the first ridge-shaped convex portion 21a and the second ridge-shaped convex portion 22a form inclined surfaces corresponding to the inclined side surfaces of the first groove-shaped concave portion 11a and the second groove-shaped concave portion 12a.

[0041] As described above, a first groove-shaped recess 11a is formed on the first panel outer surface 11s of the first panel 11, and a second groove-shaped recess 12a is formed on the second panel outer surface 12s of the second panel 12 joined adjacent to the first panel 11, and the joining member 20A has a first ridge-shaped protrusion 21a that engages with the first groove-shaped recess 11a and a second ridge-shaped protrusion 22a that engages with the second groove-shaped recess 12a, so that the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a are spaced apart and close to each other, and by engaging the first ridge-shaped protrusion 21a with the first groove-shaped recess 11a and the second ridge-shaped protrusion 22a with the second groove-shaped recess 12a, the first panel 11 and the second panel 12 can be joined together and the panels 10 can be assembled into a wall shape. In this way, the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a of the joining member 20A can be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a to join the first panel 11 and the second panel 12, thereby assembling the panel 10 into a wall-like shape, and further, the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a are spaced close to each other, resulting in excellent workability. Furthermore, by displacing the displacement member 23 relative to the sliding space 21b, the other-side joining member 22 is displaced relative to the one-side joining member 21, and the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a move closer to and away from each other, thereby facilitating engagement of the first ridge-shaped protrusion 21a with the first groove-shaped recess 11a and engagement of the second ridge-shaped protrusion 22a with the second groove-shaped recess 12a.

[0042] Figure 8 is a structural diagram showing another embodiment of a joining member used in the panel joining method of the present invention, where Figure 8(a) shows the member attached to the panel, Figure 8(b) shows the member with the first ridge-shaped protrusion and the second ridge-shaped protrusion separated from each other, and Figure 8(c) shows the member with the first ridge-shaped protrusion and the second ridge-shaped protrusion close to each other. The joining member 20B according to this embodiment is disposed at the inner corner where the first panel 11 and the second panel 12 join.

[0043] The joining member 20B has a one-side joining member 21 that forms a first ridge-shaped protrusion 21a, an other-side joining member 22 that forms a second ridge-shaped protrusion 22a, a joining member main body 24 that holds the one-side joining member 21 and the other-side joining member 22, and a displacement member 23 that is arranged in a sliding space 24a (see Figure 9) formed in the joining member main body 24. A first groove-shaped recess 11a that engages with the first ridge-shaped protrusion 21a is formed in the first panel 11, and a second groove-shaped recess 12a that engages with the second ridge-shaped protrusion 22a is formed in the second panel 12. It is preferable that the first groove-shaped recess 11a and the second groove-shaped recess 12a have inclined sides at least on the outer peripheral side of the panel 10, and that the bottom surfaces of the first groove-shaped recess 11a and the second groove-shaped recess 12a are wider than the opening surfaces.

[0044] FIG. 9 is an exploded perspective view of the joining member shown in FIG. The one-side joining member 21 has a one-side joining member sliding space 21d formed therein, and the other-side joining member 22 has a other-side joining member sliding space 22d formed therein. A first wedge portion 23c and a second wedge portion 23d are formed on the displacement member 23. The first wedge portion 23c and the second wedge portion 23d are formed to be inclined with respect to the sliding direction of the displacement member 23. The joint member body 24 is formed with a sliding space 24a in which the one-side joint member 21, the other-side joint member 22, and the displacement member 23 can be disposed. The first wedge portion 23c moves in the one-side joining member sliding space 21d, whereby the one-side joining member 21 moves relative to the joining member main body 24. The second wedge portion 23d moves in the other-side joining member sliding space 22d, whereby the other-side joining member 22 moves relative to the joining member body 24. Therefore, by displacing the displacement member 23 relative to the sliding space 24a, the one-side joining member 21 and the other-side joining member 22 are displaced relative to the joining member body 24, and the first ridge-like protrusion 21a and the second ridge-like protrusion 22a move closer to or farther apart from each other. It is preferable that the first ridge-shaped convex portion 21a and the second ridge-shaped convex portion 22a form inclined surfaces corresponding to the inclined side surfaces of the first groove-shaped concave portion 11a and the second groove-shaped concave portion 12a.

[0045] As described above, a first groove-shaped recess 11a is formed on the first panel outer surface 11s of the first panel 11, and a second groove-shaped recess 12a is formed on the second panel outer surface 12s of the second panel 12 joined adjacent to the first panel 11, and the joining member 20A has a first ridge-shaped protrusion 21a that engages with the first groove-shaped recess 11a and a second ridge-shaped protrusion 22a that engages with the second groove-shaped recess 12a, so that the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a are spaced apart and close to each other, and by engaging the first ridge-shaped protrusion 21a with the first groove-shaped recess 11a and the second ridge-shaped protrusion 22a with the second groove-shaped recess 12a, the first panel 11 and the second panel 12 can be joined together and the panels 10 can be assembled into a wall shape. In this way, the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a of the joining member 20A can be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a to join the first panel 11 and the second panel 12, thereby assembling the panel 10 into a wall-like shape, and further, the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a are spaced close to each other, resulting in excellent workability. Furthermore, by displacing the displacement member 23 relative to the sliding space 24a, the one-side joining member 21 and the other-side joining member 22 are displaced relative to the joining member main body 24, and the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a move closer to and away from each other, thereby facilitating engagement of the first ridge-shaped protrusion 21a with the first groove-shaped recess 11a and engagement of the second ridge-shaped protrusion 22a with the second groove-shaped recess 12a.

[0046] Figure 10 is a structural diagram showing yet another embodiment of a joining member used in the panel joining method of the present invention, where Figure 10(a) shows the member attached to the panel, Figure 10(b) shows the member with the first ridge-shaped protrusion and the second ridge-shaped protrusion spaced apart, and Figure 10(c) shows the member with the first ridge-shaped protrusion and the second ridge-shaped protrusion close to each other. The joining member 20C according to this embodiment is disposed at the outer corner of the joint between the first panel 11 and the second panel 12.

[0047] The joint member 20C has a first joint member 21 that forms a first ridge-like protrusion 21a and a second joint member 22 that forms a second ridge-like protrusion 22a. A first groove-shaped recess 11a that engages with the first ridge-shaped protrusion 21a is formed in the first panel 11, and a second groove-shaped recess 12a that engages with the second ridge-shaped protrusion 22a is formed in the second panel 12. It is preferable that the first groove-shaped recess 11a and the second groove-shaped recess 12a have inclined sides at least on the outer peripheral side of the panel 10, and that the bottom surfaces of the first groove-shaped recess 11a and the second groove-shaped recess 12a are wider than the opening surfaces.

[0048] FIG. 11 is an exploded perspective view of the joining member shown in FIG. The joining member 21 on one side has a sliding groove 21e with an inclined surface, and the joining member 22 on the other side has a roller portion 22e that slides along the sliding groove 21e. The sliding groove 21e is formed to be inclined in the sliding direction. Therefore, by displacing the one-side joining member 21 relative to the other-side joining member 22, the first ridge-like convex portion 21a and the second ridge-like convex portion 22a move closer to or farther apart from each other. It is preferable that the first ridge-shaped convex portion 21a and the second ridge-shaped convex portion 22a form inclined surfaces corresponding to the inclined side surfaces of the first groove-shaped concave portion 11a and the second groove-shaped concave portion 12a.

[0049] As described above, a first groove-shaped recess 11a is formed on the first panel outer surface 11s of the first panel 11, and a second groove-shaped recess 12a is formed on the second panel outer surface 12s of the second panel 12 joined adjacent to the first panel 11, and the joining member 20A has a first ridge-shaped protrusion 21a that engages with the first groove-shaped recess 11a and a second ridge-shaped protrusion 22a that engages with the second groove-shaped recess 12a, so that the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a are spaced apart and close to each other, and by engaging the first ridge-shaped protrusion 21a with the first groove-shaped recess 11a and the second ridge-shaped protrusion 22a with the second groove-shaped recess 12a, the first panel 11 and the second panel 12 can be joined together and the panels 10 can be assembled into a wall shape. In this way, the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a of the joining member 20A can be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a to join the first panel 11 and the second panel 12, thereby assembling the panel 10 into a wall-like shape, and further, the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a are spaced close to each other, resulting in excellent workability. Furthermore, by displacing the one-side joining member 21 relative to the other-side joining member 22, the first ridge-shaped convex portion 21a and the second ridge-shaped convex portion 22a move closer to and away from each other, making it easy to engage the first ridge-shaped convex portion 21a with the first groove-shaped recess 11a and the second ridge-shaped convex portion 22a with the second groove-shaped recess 12a.

[0050] Figure 12 is a structural diagram showing yet another embodiment of a joining member used in the panel joining method of the present invention, where Figure 12(a) shows the member attached to the panel, Figures 12(b) and 12(c) show the member with the first ridge-shaped protrusion and the second ridge-shaped protrusion spaced apart, and Figures 12(d) and 12(e) show the member with the first ridge-shaped protrusion and the second ridge-shaped protrusion close to each other.

[0051] The joining member 20D according to this embodiment is arranged such that the first panel 11 and the second panel 12 are arranged side by side on the same plane. By using the joining member 20D, the first panel 11 and the second panel 12 are joined together so that the first panel outer surface 11s and the second panel outer surface 12s are flush with each other. In this way, by using the joining member 20, the first panel 11 and the second panel 12 that are arranged side by side on the same plane can be easily joined together. The joint member 20D has a first joint member 21 that forms a first ridge-like protrusion 21a and a second joint member 22 that forms a second ridge-like protrusion 22a. A first groove-shaped recess 11a that engages with the first ridge-shaped protrusion 21a is formed in the first panel 11, and a second groove-shaped recess 12a that engages with the second ridge-shaped protrusion 22a is formed in the second panel 12. It is preferable that the first groove-shaped recess 11a and the second groove-shaped recess 12a have inclined sides at least on the outer peripheral side of the panel 10, and that the bottom surfaces of the first groove-shaped recess 11a and the second groove-shaped recess 12a are wider than the opening surfaces.

[0052] 13 is an exploded perspective view of the joining member shown in FIG. The joining member 21 on one side has a sliding groove 21e with an inclined surface, and the joining member 22 on the other side has a roller portion 22e that slides along the sliding groove 21e. The sliding groove 21e is formed to be inclined in the sliding direction. Therefore, by displacing the one-side joining member 21 relative to the other-side joining member 22, the first ridge-like convex portion 21a and the second ridge-like convex portion 22a move closer to or farther apart from each other. It is preferable that the first ridge-shaped convex portion 21a and the second ridge-shaped convex portion 22a form inclined surfaces corresponding to the inclined side surfaces of the first groove-shaped concave portion 11a and the second groove-shaped concave portion 12a.

[0053] As described above, a first groove-shaped recess 11a is formed on the first panel outer surface 11s of the first panel 11, and a second groove-shaped recess 12a is formed on the second panel outer surface 12s of the second panel 12 joined adjacent to the first panel 11, and the joining member 20A has a first ridge-shaped protrusion 21a that engages with the first groove-shaped recess 11a and a second ridge-shaped protrusion 22a that engages with the second groove-shaped recess 12a, so that the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a are spaced apart and close to each other, and by engaging the first ridge-shaped protrusion 21a with the first groove-shaped recess 11a and the second ridge-shaped protrusion 22a with the second groove-shaped recess 12a, the first panel 11 and the second panel 12 can be joined together and the panels 10 can be assembled into a wall shape. In this way, the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a of the joining member 20A can be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a to join the first panel 11 and the second panel 12, thereby assembling the panel 10 into a wall-like shape, and further, the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a are spaced close to each other, resulting in excellent workability. Furthermore, by displacing the one-side joining member 21 relative to the other-side joining member 22, the first ridge-shaped convex portion 21a and the second ridge-shaped convex portion 22a move closer to and away from each other, making it easy to engage the first ridge-shaped convex portion 21a with the first groove-shaped recess 11a and the second ridge-shaped convex portion 22a with the second groove-shaped recess 12a.

[0054] 14 is a structural diagram showing an embodiment of a spring retainer used in the panel joining method according to the present invention. In FIG. 14, a spring retainer 30 is attached to the first panel outer surface 11s of the first panel 11. The spring retainer 30 has a pair of legs 31 on one side and a pair of legs 32 on the other side. The pair of one-side leg portions 31 and the pair of other-side leg portions 32 extend from the deformation portion 33 in the same direction. A first ridge-shaped protrusion 31a is formed at the end of each of the pair of one-side leg portions 31, and a second ridge-shaped protrusion 32a is formed at the end of each of the pair of other-side leg portions 32. The first ridge-shaped protrusion 31a abuts against one side of the first groove-shaped recess 11a, the second ridge-shaped protrusion 32a abuts against the other side of the first groove-shaped recess 11a, and the deformation portion 33 urges the one-side leg 31 and the other-side leg 32 in a direction separating them, thereby allowing the spring retainer 30 to be attached to the first groove-shaped recess 11a.

[0055] FIG. 15 is a structural diagram showing an embodiment of an interior corner temporary fastening member used in the panel joining method according to the present invention. The interior corner temporary fastening member 40 according to this embodiment is disposed at the interior corner where the first panel 11 and the second panel 12 join. The interior corner temporary fixing member 40 is formed with a first ridge-shaped protrusion 41a and a second ridge-shaped protrusion 42a. The interior corner temporary fixing member 40 is used to temporarily fix the first panel 11 and the second panel 12 together before the joining member 20B is attached. Therefore, the first ridge-like protrusions 41a are engaged with the first groove-like recesses 11a of the first panel 11, and the second ridge-like protrusions 42a are engaged with the second groove-like recesses 12a of the second panel 12 when in use.

[0056] Fig. 16 is a structural diagram showing an embodiment of a foot fixing device used in the panel joining method according to the present invention. Fig. 16 shows a case where a foot fixing device 50 is attached to the second panel outer surface 12s of the second panel 12. The foot fixing device 50 according to this embodiment is formed with ridge-shaped protrusions 51a. It is also preferable that the foot fixing device 50 has nail holes 52 formed therein. The foot fixing device 50 can be nailed to the shim 7 by nailing it into the nailing hole 52.

[0057] 17 is a structural diagram showing an embodiment of a pressing member used in the panel joining method according to the present invention. In FIG. 17, a pressing member 60 is attached to the second panel outer surface 12s of the second panel 12. The pressing member 60 positions the pipe material 6 to be attached to the second panel outer surface 12s. 17(a) and 17(b) show a pressing member 60 for a square steel pipe, and FIG. 17(c) shows a pressing member 60 for a round steel pipe. The pressing member 60 has a pipe contact surface 62 that contacts the pipe 6, and a ridge-like protrusion 61 that engages with the first groove-like recess 11a.

[0058] FIG. 18 is a structural diagram showing an embodiment of an alignment member used in the panel joining method according to the present invention. The guide member 70 has a member body 72 having a flat surface 71 formed thereon, and a ridge-like protrusion 73 that engages with the first groove-like recess 11a and the second groove-like recess 12a.

[0059] Figure 19 is a structural diagram showing another embodiment of a joining member used in the panel joining method of the present invention, where Figure 19(a) shows the member attached to the panel, Figure 19(b) shows the member with the first ridge-shaped protrusion and the second ridge-shaped protrusion not protruding, and Figure 19(c) shows the member with the first ridge-shaped protrusion and the second ridge-shaped protrusion protruding. Figure 20 is a diagram showing the movement of the joining member shown in Figure 19, where Figure 20(a) is a diagram showing the sliding space of the ridge-shaped convex portion on one side and the sliding space of the ridge-shaped convex portion on the other side, and Figure 20(b) is a diagram showing the joining member on one side and the joining member on the other side rotated by a predetermined angle.

[0060] The joining member 20E according to this embodiment is disposed at the outer corner where the first panel 11 and the second panel 12 join. The joint member 20E has a first joint member 21 on which the first ridge-like protrusion 21a is arranged, and a second joint member 22 on which the second ridge-like protrusion 22a is arranged. One-side ridge-shaped convex portion sliding space 21f is formed in one-side joining member 21, and one-side ridge-shaped convex portion displacement member 21g is disposed in one-side ridge-shaped convex portion sliding space 21f. Also, one-side elastic member 21h is disposed in one-side ridge-shaped protrusion sliding space 21f. The one-side elastic member 21h has a pair of protruding pieces 21i that are arranged outside the one-side ridge-shaped protrusion sliding space 21f.

[0061] The other-side joining member 22 has an other-side ridge-like convex portion sliding space 22f formed therein, and an other-side ridge-like convex portion displacement member 22g is disposed in the other-side ridge-like convex portion sliding space 22f. Further, the other-side elastic member 22h is disposed in the other-side ridge-like convex portion sliding space 22f. The other-side elastic member 22h has a pair of protruding pieces 22i disposed outside the other-side ridge-shaped protrusion sliding space 22f.

[0062] The first rib-shaped protrusion 21a is formed at the end of the one-side rib-shaped protrusion displacement member 21g. Therefore, by displacing the one-side rib-shaped protrusion displacement member 21g with respect to the one-side rib-shaped protrusion sliding space 21f, the first rib-shaped protrusion 21a protrudes from the one-side rib-shaped protrusion sliding space 21f. When the first ridge-shaped protrusion 21a protrudes from the one-side ridge-shaped protrusion sliding space 21f, the pair of protruding pieces 21i of the one-side elastic member 21h spreads out on both sides of the first ridge-shaped protrusion 21a.

[0063] The second rib-shaped protrusion 22a is formed at the end of the other-side rib-shaped protrusion displacement member 22g. Therefore, by displacing the other-side rib-shaped protrusion displacement member 22g with respect to the other-side rib-shaped protrusion sliding space 22f, the second rib-shaped protrusion 22a protrudes from the other-side rib-shaped protrusion sliding space 22f. When the second ridge-shaped protrusion 22a protrudes from the other-side ridge-shaped protrusion sliding space 22f, the pair of protrusion pieces 22i of the other-side elastic member 22h spreads out on both sides of the second ridge-shaped protrusion 22a.

[0064] In this way, by protruding the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a from the one-side ridge-shaped protrusion sliding space 21f and the other-side ridge-shaped protrusion sliding space 22f, the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a can be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a. Furthermore, by having the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a protrude from the one-side ridge-shaped protrusion sliding space 21f and the other-side ridge-shaped protrusion sliding space 22f, the pair of protrusion pieces 21i, 22i spread out, and the pair of protrusion pieces 21i, 22i can firmly engage the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a with the first groove-shaped recess 11a and the second groove-shaped recess 12a. The one-side joining member 21 and the other-side joining member 22 are connected by a rotation shaft 25. The one-side joining member 21 and the other-side joining member 22 can be rotated by a predetermined angle by the rotation shaft 25. Therefore, the first ridge-shaped convex portion 21a and the second ridge-shaped convex portion 22a can easily be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a.

[0065] Figure 21 is a structural diagram showing another embodiment of a joining member used in the panel joining method of the present invention, where Figure 21(a) shows the member attached to the panel and Figure 21(b) shows the member with the first ridge-shaped protrusion protruding. Figure 22 is a diagram showing the movement of the joining member shown in Figure 21, where Figure 22(a) is a diagram showing the sliding space of the one-side ridge-shaped protrusion with the first ridge-shaped protrusion not protruding, and Figure 22(b) is a diagram showing the state in which the one-side joining member and the other-side joining member have been rotated by a predetermined angle. Note that Figure 22(b) shows the state in which the first ridge-shaped protrusion protrudes.

[0066] The joining member 20F according to this embodiment is disposed at the outer corner where the first panel 11 and the second panel 12 join. The joint member 20F has a first joint member 21 on which a first ridge-like protrusion 21a is arranged, and a second joint member 22 on which a second ridge-like protrusion 22a is arranged. One-side ridge-shaped convex portion sliding space 21f is formed in one-side joining member 21, and one-side ridge-shaped convex portion displacement member 21g is disposed in one-side ridge-shaped convex portion sliding space 21f. Also, one-side elastic member 21h is disposed in one-side ridge-shaped protrusion sliding space 21f. The one-side elastic member 21h has a pair of protruding pieces 21i that are arranged outside the one-side ridge-shaped protrusion sliding space 21f.

[0067] By displacing the one-side ridge-shaped convex portion displacement member 21g relative to the one-side ridge-shaped convex portion sliding space 21f, the first ridge-shaped convex portion 21a protrudes from the one-side ridge-shaped convex portion sliding space 21f. When the first ridge-shaped protrusion 21a protrudes from the one-side ridge-shaped protrusion sliding space 21f, the pair of protruding pieces 21i of the one-side elastic member 21h spreads out on both sides of the first ridge-shaped protrusion 21a.

[0068] In this way, by projecting the first ridge-shaped convex portion 21a from the one-side ridge-shaped convex portion sliding space 21f, the first ridge-shaped convex portion 21a can be engaged with the first groove-shaped concave portion 11a. Furthermore, by protruding the first ridge-shaped protrusion 21a from the one-side ridge-shaped protrusion sliding space 21f, the pair of protruding pieces 21i spreads out, and the pair of protruding pieces 21i allows the first ridge-shaped protrusion 21a to be firmly engaged with the first groove-shaped recess 11a. The one-side joining member 21 and the other-side joining member 22 are connected by a rotation shaft 25. The one-side joining member 21 and the other-side joining member 22 can be rotated by a predetermined angle by the rotation shaft 25. Therefore, the first ridge-shaped convex portion 21a and the second ridge-shaped convex portion 22a can easily be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a.

[0069] Figure 23 is a structural diagram showing another embodiment of a joining member used in the panel joining method of the present invention, where Figure 23(a) shows the member attached to the panel, Figure 23(b) shows the member with the first ridge-shaped protrusion and the second ridge-shaped protrusion not protruding, and Figure 23(c) shows the member with the first ridge-shaped protrusion and the second ridge-shaped protrusion protruding. Figure 24 is a structural diagram showing the sliding space of the ridge-shaped protrusion on one side of the joining member shown in Figure 23, where Figure 24(a) shows a state in which the first ridge-shaped protrusion is not protruding, and Figure 24(b) shows a state in which the first ridge-shaped protrusion is protruding. The joining member 20G according to this embodiment is disposed at the inner corner of the joint between the first panel 11 and the second panel 12.

[0070] The joining member 20G forms a one-side rib-like-protrusion sliding space 21f in which the first rib-like protrusion 21a is disposed, and a second-side rib-like-protrusion sliding space in which the second rib-like protrusion 22a is disposed. The second-side rib-like-protrusion sliding space is not shown, but has the same configuration as the one-side rib-like-protrusion sliding space 21f. The joining member 20G has a member body formed with a one-side ridge-shaped protrusion sliding space 21f and an other-side ridge-shaped protrusion sliding space. In this embodiment, the member body is a hexahedron. The one-side ridge-shaped protrusion sliding space 21f and the other-side ridge-shaped protrusion sliding space are arranged in perpendicular directions. One-side ridge-shaped protrusion displacement member 21g is disposed in one-side ridge-shaped protrusion sliding space 21f, and another-side ridge-shaped protrusion displacement member 22g is disposed in the other-side ridge-shaped protrusion sliding space. One-side elastic member 21h is disposed in one-side ridge-shaped protrusion sliding space 21f, and the other-side elastic member is disposed in the other-side ridge-shaped protrusion sliding space. The other-side elastic member is not shown, but has the same configuration as one-side elastic member 21h. The one-side elastic member 21h has a pair of protruding pieces 21i arranged outside the one-side ridge-shaped convex portion sliding space 21f. The other-side elastic member also has a pair of protruding pieces 22i arranged outside the other-side ridge-shaped convex portion sliding space, similar to the one-side elastic member 21h.

[0071] The first rib-shaped protrusion 21a is formed at the end of the one-side rib-shaped protrusion displacement member 21g. Therefore, by displacing the one-side rib-shaped protrusion displacement member 21g with respect to the one-side rib-shaped protrusion sliding space 21f, the first rib-shaped protrusion 21a protrudes from the one-side rib-shaped protrusion sliding space 21f. When the first ridge-shaped protrusion 21a protrudes from the one-side ridge-shaped protrusion sliding space 21f, the pair of protruding pieces 21i of the one-side elastic member 21h spreads out on both sides of the first ridge-shaped protrusion 21a.

[0072] The second ridge-shaped protrusion 22a is formed at the end of the other-side rib-shaped protrusion displacement member 22g. Therefore, by displacing the other-side rib-shaped protrusion displacement member 22g with respect to the other-side rib-shaped protrusion sliding space, the second rib-shaped protrusion 22a protrudes from the other-side rib-shaped protrusion sliding space. When the second ridge-shaped protrusion 22a protrudes from the other-side ridge-shaped protrusion sliding space, the pair of protruding pieces 22i of the other-side elastic member spreads out on both sides of the second ridge-shaped protrusion 22a.

[0073] In this way, by protruding the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a from the one-side ridge-shaped protrusion sliding space 21f and the other-side ridge-shaped protrusion sliding space, the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a can be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a. Furthermore, by having the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a protrude from the one-side ridge-shaped protrusion sliding space 21f and the other-side ridge-shaped protrusion sliding space, the pair of protrusion pieces 21i, 22i spread out, and the pair of protrusion pieces 21i, 22i can firmly engage the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a with the first groove-shaped recess 11a and the second groove-shaped recess 12a.

The foot fixing device 50A according to this embodiment is formed with a ridge-like protrusion 51a. The foot fixing device 50A is attached to the first panel 11 or the second panel 12 by engaging the ridge-like protrusion 51a with the first groove-like recess 11a or the second groove-like recess 12a. It is also preferable that the foot fixing device 50A has nail holes 52 formed therein. The foot fixing device 50A can be fastened to the shim 7 or the like by nailing it into the nailing holes 52. A ridge-shaped protrusion sliding space 51f is formed in the foot fixture 50A, and a ridge-shaped protrusion displacement member 51g is disposed in the ridge-shaped protrusion sliding space 51f. The ridge-shaped protrusion 51a is formed at the end of the ridge-shaped protrusion displacement member 51g. By displacing the ridge-shaped protrusion displacement member 51g with respect to the ridge-shaped protrusion sliding space 51f, the ridge-shaped protrusion 51a protrudes from the ridge-shaped protrusion sliding space 51f. In this way, by protruding the ridge-shaped convex portion 51a from the ridge-shaped convex portion sliding space 51f, it can be engaged with the first groove-shaped recess 11a or the second groove-shaped recess 12a, making it easy to attach the foot fixing device 50A to the first panel 11 or the second panel 12. An elastic member 51h is disposed in the ridge-shaped protrusion sliding space 51f. The elastic member 51h has a pair of protruding pieces 51i. In a state where the ridge-shaped protrusion 51a protrudes from the ridge-shaped protrusion sliding space 51f, the pair of protruding pieces 51i of the elastic member 51h spreads out on both sides of the ridge-shaped protrusion 51a. In this way, by protruding the ridge-shaped protrusion 51a from the ridge-shaped protrusion sliding space 51f, the pair of protrusion pieces 51i spreads out, and the pair of protrusion pieces 51i can be firmly engaged with the first groove-shaped recess 11a or the second groove-shaped recess 12a.

A ridge-shaped protrusion sliding space 61f is formed in the pressing member 60A, and a ridge-shaped protrusion displacement member 61g is arranged in the ridge-shaped protrusion sliding space 61f. By displacing the ridge-shaped protrusion displacement member 61g relative to the ridge-shaped protrusion sliding space 61f, the ridge-shaped protrusion 61a protrudes from the ridge-shaped protrusion sliding space 61f.

An elastic member 61h is disposed in the ridge-shaped protrusion sliding space 61f. The elastic member 61h has a pair of protruding pieces 61i. In a state where the ridge-shaped protrusion 61a protrudes from the ridge-shaped protrusion sliding space 61f, the pair of protruding pieces 61i of the elastic member 61h spreads out on both sides of the ridge-shaped protrusion 61a. In this way, by protruding the ridge-shaped protrusion 61a from the ridge-shaped protrusion sliding space 61f, the pair of protrusion pieces 61i spreads out, and the pair of protrusion pieces 61i can be firmly engaged with the first groove-shaped recess 11a or the second groove-shaped recess 12a.

[0078] Figure 27 is a structural diagram showing another embodiment of a pressing member used in the panel joining method of the present invention, where Figure 27(a) shows a state in which the ridge-shaped protrusions do not protrude, Figure 27(b) shows a state in which the ridge-shaped protrusions do not protrude and the ridge-shaped protrusion sliding space is visible, Figure 27(c) shows a state in which the ridge-shaped protrusions protrude, and Figure 27(d) shows a state in which the ridge-shaped protrusions protrude and the ridge-shaped protrusion sliding space is visible. The holding member 60B is attached to the first groove-shaped recess 11a of the first panel 11 or the second groove-shaped recess 12a of the second panel 12, thereby fixing the pipe material 6 to the first panel outer surface 11s or the second panel outer surface 12s. The holding member 60B is used to fix a pipe material 6 having a polygonal cross section, such as a square steel pipe. The pressing member 60B has a ridge-shaped protrusion 61a that engages with the first groove-shaped recess 11a or the second groove-shaped recess 12a, and a pipe contact surface 62 that contacts the pipe material 6.

[0079] The pressing member 60B according to this embodiment has ridge-shaped protrusions 61a formed thereon. The pressing member 60B is attached to the first panel 11 or the second panel 12 by engaging the ridge-shaped protrusions 61a with the first groove-shaped recesses 11a or the second groove-shaped recesses 12a. A ridge-shaped protrusion sliding space 61f is formed in the pressing member 60B, and a ridge-shaped protrusion displacement member 61g is arranged in the ridge-shaped protrusion sliding space 61f. By displacing the ridge-shaped protrusion displacement member 61g relative to the ridge-shaped protrusion sliding space 61f, the ridge-shaped protrusion 61a protrudes from the ridge-shaped protrusion sliding space 61f. In this way, by protruding the ridge-shaped protrusion 61a from the ridge-shaped protrusion sliding space 61f, it can be engaged with the first groove-shaped recess 11a or the second groove-shaped recess 12a, making it easy to attach the pressing member 60B to the first panel 11 or the second panel 12. An elastic member 61h is disposed in the ridge-shaped protrusion sliding space 61f. The elastic member 61h has a pair of protruding pieces 61i. In a state where the ridge-shaped protrusion 61a protrudes from the ridge-shaped protrusion sliding space 61f, the pair of protruding pieces 61i of the elastic member 61h spreads out on both sides of the ridge-shaped protrusion 61a. In this way, by protruding the ridge-shaped protrusion 61a from the ridge-shaped protrusion sliding space 61f, the pair of protrusion pieces 61i spreads out, and the pair of protrusion pieces 61i can be firmly engaged with the first groove-shaped recess 11a or the second groove-shaped recess 12a.

[0080] Figure 28 is a structural diagram showing yet another embodiment of a joining member used in the panel joining method according to the present invention, where Figure 28(a) is a structural diagram of the state attached to a panel, Figure 28(b) is a structural diagram of the state in which the first ridge-shaped convex portion does not protrude and the second ridge-shaped convex portion protrudes, and Figure 28(c) is a structural diagram in which the sliding spaces of the ridge-shaped convex portion on one side and the other side in Figure 28(b) are visible.

[0081] The joining member 20H according to this embodiment is arranged such that the first panel 11 and the second panel 12 are arranged side by side on the same plane. By using the joining member 20H, the first panel 11 and the second panel 12 are joined together so that the first panel outer surface 11s and the second panel outer surface 12s are flush with each other. In this way, by using the joining member 20H, the first panel 11 and the second panel 12 that are arranged side by side on the same plane can be easily joined together.

[0082] The joining member 20H forms a one-side ridge-shaped protrusion sliding space 21f in which the first ridge-shaped protrusion 21a is disposed, and forms an other-side ridge-shaped protrusion sliding space 22f in which the second ridge-shaped protrusion 22a is disposed. The joining member 20H has a first-side ridge-shaped protrusion sliding space 21f and an second-side ridge-shaped protrusion sliding space 22f formed in the member body. In this embodiment, the member body is a hexahedron. The first-side ridge-shaped protrusion sliding space 21f and the second-side ridge-shaped protrusion sliding space 22f are parallel to each other, and the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a protrude in the same direction. One-side ridge-shaped protrusion displacement member 21g is arranged in one-side ridge-shaped protrusion sliding space 21f, and another-side ridge-shaped protrusion displacement member 22g is arranged in the other-side ridge-shaped protrusion sliding space 22f. A one-side elastic member 21h is disposed in the one-side ridge-shaped convex portion sliding space 21f, and a second-side elastic member 22h is disposed in the other-side ridge-shaped convex portion sliding space 22f. The first elastic member 21h has a pair of protruding pieces 21i arranged outside the first ridge-shaped convex portion sliding space 21f. The second elastic member 22h, like the first elastic member 21h, also has a pair of protruding pieces 22i arranged outside the second ridge-shaped convex portion sliding space 22f.

[0083] The first rib-shaped protrusion 21a is formed at the end of the one-side rib-shaped protrusion displacement member 21g. Therefore, by displacing the one-side rib-shaped protrusion displacement member 21g with respect to the one-side rib-shaped protrusion sliding space 21f, the first rib-shaped protrusion 21a protrudes from the one-side rib-shaped protrusion sliding space 21f. When the first ridge-shaped protrusion 21a protrudes from the one-side ridge-shaped protrusion sliding space 21f, the pair of protruding pieces 21i of the one-side elastic member 21h spreads out on both sides of the first ridge-shaped protrusion 21a.

[0084] The second rib-shaped protrusion 22a is formed at the end of the other-side rib-shaped protrusion displacement member 22g. Therefore, by displacing the other-side rib-shaped protrusion displacement member 22g with respect to the other-side rib-shaped protrusion sliding space 22f, the second rib-shaped protrusion 22a protrudes from the other-side rib-shaped protrusion sliding space 22f. When the second ridge-shaped protrusion 22a protrudes from the other-side ridge-shaped protrusion sliding space 22f, the pair of protrusion pieces 22i of the other-side elastic member 22h spreads out on both sides of the second ridge-shaped protrusion 22a.

[0085] In this way, by protruding the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a from the one-side ridge-shaped protrusion sliding space 21f and the other-side ridge-shaped protrusion sliding space 22f, the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a can be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a. Furthermore, by having the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a protrude from the one-side ridge-shaped protrusion sliding space 21f and the other-side ridge-shaped protrusion sliding space 22f, the pair of protrusion pieces 21i, 22i spread out, and the pair of protrusion pieces 21i, 22i can firmly engage the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a with the first groove-shaped recess 11a and the second groove-shaped recess 12a.

[0086] One-side rib-shaped protrusion displacement member 21g is provided with one-side return cam member 21j, and the other-side rib-shaped protrusion displacement member 22g is provided with a other-side return cam member 22j. One-side return cam member 21j is rotatably attached to one-side rib-shaped protrusion displacement member 21g, and the other-side return cam member 22j is rotatably attached to the other-side rib-shaped protrusion displacement member 22g. By rotating one-side return cam member 21j or the other-side return cam member 22j with first rib-shaped protrusion 21a or second rib-shaped protrusion 22a protruding, the first rib-shaped protrusion 21a or second rib-shaped protrusion 22a can be returned to one-side rib-shaped protrusion sliding space 21f or the other-side rib-shaped protrusion sliding space 22f.

[0087] Figure 29 is a structural diagram showing yet another embodiment of a joining member used in the panel joining method of the present invention, where Figure 29(a) is a structural diagram showing a state in which the first ridge-shaped convex portion does not protrude and the second ridge-shaped convex portion protrudes, Figure 28(b) is a structural diagram in which the ridge-shaped convex portion sliding space on one side and the ridge-shaped convex portion sliding space on the other side in Figure 28(a) are visible, Figure 29(c) is a structural diagram seen from the side in which the first ridge-shaped convex portion protrudes, and Figure 29(d) is a structural diagram seen from the side in which the first ridge-shaped convex portion does not protrude.

[0088] In the joining member 20J according to this embodiment, the first panel 11 and the second panel 12 are arranged side by side on the same plane, similar to the embodiment shown in FIG. By using the joining member 20J, the first panel 11 and the second panel 12 are joined together so that the first panel outer surface 11s and the second panel outer surface 12s are flush with each other. In this way, by using the joining member 20J, the first panel 11 and the second panel 12 that are arranged side by side on the same plane can be easily joined together.

[0089] The joining member 20J forms a one-side ridge-shaped protrusion sliding space 21f in which the first ridge-shaped protrusion 21a is disposed, and a other-side ridge-shaped protrusion sliding space 22f in which the second ridge-shaped protrusion 22a is disposed. The joining member 20J has a member body formed with a first-side ridge-shaped protrusion sliding space 21f and an second-side ridge-shaped protrusion sliding space 22f. In this embodiment, the member body is a hexahedron. The first-side ridge-shaped protrusion sliding space 21f and the second-side ridge-shaped protrusion sliding space 22f are parallel to each other, and the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a protrude in the same direction. One-side ridge-shaped protrusion displacement member 21g is arranged in one-side ridge-shaped protrusion sliding space 21f, and another-side ridge-shaped protrusion displacement member 22g is arranged in the other-side ridge-shaped protrusion sliding space 22f. A one-side elastic member 21h is disposed in the one-side ridge-shaped convex portion sliding space 21f, and a second-side elastic member 22h is disposed in the other-side ridge-shaped convex portion sliding space 22f. The first elastic member 21h has a pair of protruding pieces 21i arranged outside the first ridge-shaped convex portion sliding space 21f. The second elastic member 22h, like the first elastic member 21h, also has a pair of protruding pieces 22i arranged outside the second ridge-shaped convex portion sliding space 22f.

[0090] The first rib-shaped protrusion 21a is formed at the end of the one-side rib-shaped protrusion displacement member 21g. Therefore, by displacing the one-side rib-shaped protrusion displacement member 21g with respect to the one-side rib-shaped protrusion sliding space 21f, the first rib-shaped protrusion 21a protrudes from the one-side rib-shaped protrusion sliding space 21f. When the first ridge-shaped protrusion 21a protrudes from the one-side ridge-shaped protrusion sliding space 21f, the pair of protruding pieces 21i of the one-side elastic member 21h spreads out on both sides of the first ridge-shaped protrusion 21a.

[0091] The second rib-shaped protrusion 22a is formed at the end of the other-side rib-shaped protrusion displacement member 22g. Therefore, by displacing the other-side rib-shaped protrusion displacement member 22g with respect to the other-side rib-shaped protrusion sliding space 22f, the second rib-shaped protrusion 22a protrudes from the other-side rib-shaped protrusion sliding space 22f. When the second ridge-shaped protrusion 22a protrudes from the other-side ridge-shaped protrusion sliding space 22f, the pair of protrusion pieces 22i of the other-side elastic member 22h spreads out on both sides of the second ridge-shaped protrusion 22a.

[0092] In this way, by protruding the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a from the one-side ridge-shaped protrusion sliding space 21f and the other-side ridge-shaped protrusion sliding space 22f, the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a can be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a. Furthermore, by having the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a protrude from the one-side ridge-shaped protrusion sliding space 21f and the other-side ridge-shaped protrusion sliding space 22f, the pair of protrusion pieces 21i, 22i spread out, and the pair of protrusion pieces 21i, 22i can firmly engage the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a with the first groove-shaped recess 11a and the second groove-shaped recess 12a.

[0093] The one-side ridge-shaped protrusion displacement member 21g is composed of a one-side ridge-shaped protrusion displacement member main body 21g1 which forms the first ridge-shaped protrusion 21a at its end, a one-side ridge-shaped protrusion displacement member operating body 21g3 which has a rotation fulcrum 21g2 on the member main body, and a one-side ridge-shaped protrusion displacement member link body 21g4. One end of the one-side ridge-shaped protrusion displacement member link body 21g4 has a pivot point 21g5 on the one-side ridge-shaped protrusion displacement member main body 21g1, and the other end of the one-side ridge-shaped protrusion displacement member link body 21g4 has a pivot point 21g6 on the one-side ridge-shaped protrusion displacement member operating body 21g3. The other-side ridge-shaped convex portion displacement member 22g has the same configuration as the one-side ridge-shaped convex portion displacement member 21g. With this configuration, by rotating the one-side ridge-shaped protrusion displacement member operating body 21g3 about the rotation fulcrum 21g2, the first ridge-shaped protrusion 21a can be protruded from the one-side ridge-shaped protrusion sliding space 21f, or the first ridge-shaped protrusion 21a can be returned to the one-side ridge-shaped protrusion sliding space 21f.

[0094] Figure 30 is a diagram showing yet another embodiment of a joining member used in the panel joining method according to the present invention, where Figure 30(a) is a diagram showing a state in which the second ridge-shaped convex portion is not protruding, Figure 30(b) is a diagram showing a state in which the second ridge-shaped convex portion is protruding, and Figure 30(c) is a diagram showing a state in which the second ridge-shaped convex portion is returned to the other-side ridge-shaped convex portion sliding space by the other-side return cam member.

[0095] The joining member 20K according to this embodiment is disposed at the outer corner of the joining portion between the first panel 11 and the second panel 12, similar to the embodiments shown in FIGS. The joint member 20K has a first joint member 21 on which the first ridge-shaped protrusion 21a is arranged, and a second joint member 22 on which the second ridge-shaped protrusion 22a is arranged. A one-side ridge-shaped convex portion sliding space (not shown) is formed in one-side joining member 21, and a one-side ridge-shaped convex portion displacement member 21g is disposed in the one-side ridge-shaped convex portion sliding space (not shown). Also, a one-side elastic member (not shown) is disposed in the one-side ridge-like convex portion sliding space (not shown). The one-side elastic member (not shown) has a pair of protruding pieces 21i that are arranged outside the one-side ridge-shaped protrusion sliding space (not shown).

[0096] An other-side ridge-shaped convex portion sliding space (not shown) is formed in the other-side joining member 22, and an other-side ridge-shaped convex portion displacement member 22g is disposed in the other-side ridge-shaped convex portion sliding space (not shown). Further, an other-side elastic member (not shown) is disposed in the other-side ridge-like convex portion sliding space (not shown). The other elastic member (not shown) has a pair of protruding pieces 22i that are arranged outside the other ridge-like protrusion sliding space (not shown).

[0097] By displacing the one-side ridge-shaped convex portion displacement member 21g relative to the one-side ridge-shaped convex portion sliding space (not shown), the first ridge-shaped convex portion 21a protrudes from the one-side ridge-shaped convex portion sliding space (not shown). When the first ridge-shaped protrusion 21a protrudes from the one-side ridge-shaped protrusion sliding space (not shown), the pair of protruding pieces 21i of the one-side elastic member (not shown) spreads out on both sides of the first ridge-shaped protrusion 21a.

[0098] By displacing the other-side ridge-shaped convex portion displacement member 22g relative to the other-side ridge-shaped convex portion sliding space (not shown), the second ridge-shaped convex portion 22a protrudes from the other-side ridge-shaped convex portion sliding space (not shown). When the second ridge-shaped protrusion 22a protrudes from the other-side ridge-shaped protrusion sliding space (not shown), the pair of protruding pieces 22i of the other-side elastic member (not shown) spreads out on both sides of the second ridge-shaped protrusion 22a.

[0099] In this way, by protruding the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a from one side ridge-shaped protrusion sliding space (not shown) and the other side ridge-shaped protrusion sliding space (not shown), the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a can be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a. Furthermore, by having the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a protrude from one side ridge-shaped protrusion sliding space (not shown) and the other side ridge-shaped protrusion sliding space (not shown), the pair of protrusion pieces 21i, 22i spread out, and the pair of protrusion pieces 21i, 22i can firmly engage the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a with the first groove-shaped recess 11a and the second groove-shaped recess 12a. The one-side joining member 21 and the other-side joining member 22 are connected by a rotation shaft 25. The one-side joining member 21 and the other-side joining member 22 can be rotated by a predetermined angle by the rotation shaft 25. Therefore, the first ridge-shaped convex portion 21a and the second ridge-shaped convex portion 22a can easily be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a.

[0100] One-side rib-shaped protrusion displacement member 21g is provided with a one-side return cam member (not shown), and the other-side rib-shaped protrusion displacement member 22g is provided with a other-side return cam member 22j. The one-side return cam member (not shown) is rotatably attached to one-side rib-shaped protrusion displacement member 21g, and the other-side return cam member 22j is rotatably attached to the other-side rib-shaped protrusion displacement member 22g. By rotating one-side return cam member 21j or the other-side return cam member 22j while first rib-shaped protrusion 21a or second rib-shaped protrusion 22a is protruding, first rib-shaped protrusion 21a or second rib-shaped protrusion 22a can be returned to the one-side rib-shaped protrusion sliding space (not shown) or the other-side rib-shaped protrusion sliding space (not shown). 30(a), the other-side ridge-shaped protrusion displacement member 22g is pressed against the member main body, causing the second ridge-shaped protrusion 22a to protrude. At this time, as shown in FIG. 30(b), the other-side return cam member 22j abuts against the main body and rotates a predetermined angle. Then, by pressing the other return cam member 22j in the direction of the arrow shown in FIG. 30(c), the second ridge-shaped convex portion 22a can be returned in the direction of the other-side ridge-shaped convex portion sliding space (not shown).

[0101] Figure 31 is a structural diagram showing yet another embodiment of a joining member used in the panel joining method of the present invention, where Figure 31(a) shows a state corresponding to Figure 19(a), Figure 31(b) shows a state in which the first ridge-shaped convex portion and the second ridge-shaped convex portion do not protrude, and Figure 31(c) shows a state in which the first ridge-shaped convex portion and the second ridge-shaped convex portion protrude. Figure 32 is a diagram showing the movement of the joining member shown in Figure 30, where Figure 32(a) is a diagram showing the sliding space of the ridge-shaped convex portion on one side and the sliding space of the ridge-shaped convex portion on the other side, and Figure 32(b) is a diagram showing the joining member on one side and the joining member on the other side rotated by a predetermined angle.

[0102] The joining member 20L according to this embodiment is disposed at the outer corner of the joint between the first panel 11 and the second panel 12. The joint member 20L has a first joint member 21 on which a first ridge-like protrusion 21a is arranged, and a second joint member 22 on which a second ridge-like protrusion 22a is arranged. One-side ridge-shaped convex portion sliding space 21f is formed in one-side joining member 21, and one-side ridge-shaped convex portion displacement member 21g is disposed in one-side ridge-shaped convex portion sliding space 21f. Also, one-side elastic member 21h is disposed in one-side ridge-shaped protrusion sliding space 21f. The one-side elastic member 21h has a pair of protruding pieces 21i that are arranged outside the one-side ridge-shaped protrusion sliding space 21f.

[0103] The other-side joining member 22 has an other-side ridge-like convex portion sliding space 22f formed therein, and an other-side ridge-like convex portion displacement member 22g is disposed in the other-side ridge-like convex portion sliding space 22f. Further, the other-side elastic member 22h is disposed in the other-side ridge-like convex portion sliding space 22f. The other-side elastic member 22h has a pair of protruding pieces 22i disposed outside the other-side ridge-shaped protrusion sliding space 22f.

[0104] The first rib-shaped protrusion 21a is formed at the end of the one-side rib-shaped protrusion displacement member 21g. Therefore, by displacing the one-side rib-shaped protrusion displacement member 21g with respect to the one-side rib-shaped protrusion sliding space 21f, the first rib-shaped protrusion 21a protrudes from the one-side rib-shaped protrusion sliding space 21f. When the first ridge-shaped protrusion 21a protrudes from the one-side ridge-shaped protrusion sliding space 21f, the pair of protruding pieces 21i of the one-side elastic member 21h spreads out on both sides of the first ridge-shaped protrusion 21a.

[0105] The second rib-shaped protrusion 22a is formed at the end of the other-side rib-shaped protrusion displacement member 22g. Therefore, by displacing the other-side rib-shaped protrusion displacement member 22g with respect to the other-side rib-shaped protrusion sliding space 22f, the second rib-shaped protrusion 22a protrudes from the other-side rib-shaped protrusion sliding space 22f. When the second ridge-shaped protrusion 22a protrudes from the other-side ridge-shaped protrusion sliding space 22f, the pair of protrusion pieces 22i of the other-side elastic member 22h spreads out on both sides of the second ridge-shaped protrusion 22a.

[0106] In this way, by protruding the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a from the one-side ridge-shaped protrusion sliding space 21f and the other-side ridge-shaped protrusion sliding space 22f, the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a can be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a. Furthermore, by having the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a protrude from the one-side ridge-shaped protrusion sliding space 21f and the other-side ridge-shaped protrusion sliding space 22f, the pair of protrusion pieces 21i, 22i spread out, and the pair of protrusion pieces 21i, 22i can firmly engage the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a with the first groove-shaped recess 11a and the second groove-shaped recess 12a. The one-side joining member 21 and the other-side joining member 22 are connected by a rotation shaft 25. The one-side joining member 21 and the other-side joining member 22 can be rotated by a predetermined angle by the rotation shaft 25. Therefore, the first ridge-shaped convex portion 21a and the second ridge-shaped convex portion 22a can easily be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a.

[0107] In this embodiment, as in the embodiment shown in Figure 29, the one-side ridge-shaped protrusion displacement member 21g is composed of a one-side ridge-shaped protrusion displacement member main body 21g1 having the first ridge-shaped protrusion 21a formed at its end, a one-side ridge-shaped protrusion displacement member operating body 21g3 having a pivot point 21g2 on the member main body, and a one-side ridge-shaped protrusion displacement member link body 21g4. One end of the one-side ridge-shaped protrusion displacement member link body 21g4 has a pivot point 21g5 on the one-side ridge-shaped protrusion displacement member main body 21g1, and the other end of the one-side ridge-shaped protrusion displacement member link body 21g4 has a pivot point 21g6 on the one-side ridge-shaped protrusion displacement member operating body 21g3. The other-side ridge-shaped convex portion displacement member 22g has the same configuration as the one-side ridge-shaped convex portion displacement member 21g. With this configuration, by rotating the one-side ridge-shaped protrusion displacement member operating body 21g3 about the rotation fulcrum 21g2, the first ridge-shaped protrusion 21a can be protruded from the one-side ridge-shaped protrusion sliding space 21f, or the first ridge-shaped protrusion 21a can be returned to the one-side ridge-shaped protrusion sliding space 21f.

[0108] Figure 33 is a structural diagram showing yet another embodiment of a joining member used in the panel joining method of the present invention, where Figure 33(a) shows a state corresponding to Figure 23(a), Figure 33(b) shows a state in which the first ridge-shaped convex portion and the second ridge-shaped convex portion do not protrude, and Figure 33(c) shows a state in which the first ridge-shaped convex portion and the second ridge-shaped convex portion protrude. The joining member 20M according to this embodiment is disposed at the inner corner of the joint between the first panel 11 and the second panel 12.

[0109] The joining member 20M forms a one-side rib-like-protrusion sliding space (not shown) in which the first rib-like protrusion 21 a is disposed, and a other-side rib-like-protrusion sliding space (not shown) in which the second rib-like protrusion 22 a is disposed. The one-side rib-like-protrusion sliding space and the other-side rib-like-protrusion sliding space are the same as the one-side rib-like-protrusion sliding space 21 f and the other-side rib-like-protrusion sliding space 22 f described in other embodiments. The joining member 20M has a member body formed with a ridge-like protrusion sliding space on one side and a ridge-like protrusion sliding space on the other side. In this embodiment, the member body is a hexahedron. The ridge-like protrusion sliding space on one side and the ridge-like protrusion sliding space on the other side are arranged in perpendicular directions. One-side ridge-shaped protrusion displacement member 21g is disposed in one-side ridge-shaped protrusion sliding space, and another-side ridge-shaped protrusion displacement member 22g is disposed in the other-side ridge-shaped protrusion sliding space. A first elastic member (not shown) is disposed in the first ridge-shaped convex portion sliding space, and a second elastic member (not shown) is disposed in the second ridge-shaped convex portion sliding space. The first elastic member and the second elastic member have the same configuration as the first elastic member 21h and the second elastic member 22h described in other embodiments. The one-side elastic member has a pair of protruding pieces 21i arranged outside the one-side ridge-shaped convex portion sliding space. Similarly to the one-side elastic member, the other-side elastic member also has a pair of protruding pieces 22i arranged outside the other-side ridge-shaped convex portion sliding space.

[0110] The first rib-shaped protrusion 21a is formed at the end of the one-side rib-shaped protrusion displacement member 21g. Therefore, by displacing the one-side rib-shaped protrusion displacement member 21g with respect to the one-side rib-shaped protrusion sliding space, the first rib-shaped protrusion 21a protrudes from the one-side rib-shaped protrusion sliding space. When the first ridge-shaped protrusion 21a protrudes from the one-side ridge-shaped protrusion sliding space, the pair of protruding pieces 21i of the one-side elastic member spreads out on both sides of the first ridge-shaped protrusion 21a.

[0111] The second ridge-shaped protrusion 22a is formed at the end of the other-side rib-shaped protrusion displacement member 22g. Therefore, by displacing the other-side rib-shaped protrusion displacement member 22g with respect to the other-side rib-shaped protrusion sliding space, the second rib-shaped protrusion 22a protrudes from the other-side rib-shaped protrusion sliding space. When the second ridge-shaped protrusion 22a protrudes from the other-side ridge-shaped protrusion sliding space, the pair of protruding pieces 22i of the other-side elastic member spreads out on both sides of the second ridge-shaped protrusion 22a.

[0112] In this way, by protruding the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a from the one-side ridge-shaped protrusion sliding space 21f and the other-side ridge-shaped protrusion sliding space, the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a can be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a. Furthermore, by having the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a protrude from the one-side ridge-shaped protrusion sliding space 21f and the other-side ridge-shaped protrusion sliding space, the pair of protrusion pieces 21i, 22i spread out, and the pair of protrusion pieces 21i, 22i can firmly engage the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a with the first groove-shaped recess 11a and the second groove-shaped recess 12a.

[0113] In this embodiment, as in the embodiment shown in Figure 29, the one-side ridge-shaped protrusion displacement member 21g is composed of a one-side ridge-shaped protrusion displacement member main body 21g1 having the first ridge-shaped protrusion 21a formed at its end, a one-side ridge-shaped protrusion displacement member operating body 21g3 having a pivot point 21g2 on the member main body, and a one-side ridge-shaped protrusion displacement member link body 21g4. One end of the one-side ridge-shaped protrusion displacement member link body 21g4 has a pivot point 21g5 on the one-side ridge-shaped protrusion displacement member main body 21g1, and the other end of the one-side ridge-shaped protrusion displacement member link body 21g4 has a pivot point 21g6 on the one-side ridge-shaped protrusion displacement member operating body 21g3. The other-side ridge-shaped convex portion displacement member 22g has the same configuration as the one-side ridge-shaped convex portion displacement member 21g. With this configuration, by rotating the one-side ridge-shaped protrusion displacement member operating body 21g3 about the rotation fulcrum 21g2, the first ridge-shaped protrusion 21a can be protruded from the one-side ridge-shaped protrusion sliding space 21f, or the first ridge-shaped protrusion 21a can be returned to the one-side ridge-shaped protrusion sliding space 21f.

[0114] Figure 34 is a structural diagram showing yet another embodiment of a foot fixing device used in the panel joining method of the present invention, where Figure 34(a) shows the state in which the ridge-shaped convex portion protrudes, Figure 34(b) shows the state in which it does not protrude, Figure 34(c) shows the state in which the ridge-shaped convex portion protrudes with the ridge-shaped convex portion sliding space visible, and Figure 25(b) shows the state in which the ridge-shaped convex portion does not protrude with the ridge-shaped convex portion sliding space visible.

[0115] The foot fixing device 50B is attached to the first groove-shaped recess 11a of the first panel 11 or the second groove-shaped recess 12a of the second panel 12, thereby fixing the first panel 11 or the second panel 12 to the base. The foot fixing device 50B according to this embodiment is formed with a ridge-like protrusion 51a. The foot fixing device 50B is attached to the first panel 11 or the second panel 12 by engaging the ridge-like protrusion 51a with the first groove-like recess 11a or the second groove-like recess 12a. In addition, it is preferable that nail holes 52 are formed in the foot fixing device 50B. The foot fixing device 50B can be fastened to the shim 7 or the like by nailing it into the nailing holes 52. A ridge-shaped protrusion sliding space 51f is formed in the foot fixture 50B, and a ridge-shaped protrusion displacement member 51g is disposed in the ridge-shaped protrusion sliding space 51f. The ridge-shaped protrusion 51a is formed at the end of the ridge-shaped protrusion displacement member 51g. By displacing the ridge-shaped protrusion displacement member 51g with respect to the ridge-shaped protrusion sliding space 51f, the ridge-shaped protrusion 51a protrudes from the ridge-shaped protrusion sliding space 51f.

[0116] In this way, by protruding the ridge-shaped convex portion 51a from the ridge-shaped convex portion sliding space 51f, it can be engaged with the first groove-shaped recess 11a or the second groove-shaped recess 12a, making it easy to attach the foot fixing device 50A to the first panel 11 or the second panel 12. An elastic member 51h is disposed in the ridge-shaped protrusion sliding space 51f. The elastic member 51h has a pair of protruding pieces 51i. In a state where the ridge-shaped protrusion 51a protrudes from the ridge-shaped protrusion sliding space 51f, the pair of protruding pieces 51i of the elastic member 51h spreads out on both sides of the ridge-shaped protrusion 51a. In this way, by protruding the ridge-shaped protrusion 51a from the ridge-shaped protrusion sliding space 51f, the pair of protrusion pieces 51i spreads out, and the pair of protrusion pieces 51i can be firmly engaged with the first groove-shaped recess 11a or the second groove-shaped recess 12a.

[0117] The ridge-shaped protrusion displacement member 51g is composed of a ridge-shaped protrusion displacement member main body 51g1 which forms the ridge-shaped protrusion 51a at its end, a ridge-shaped protrusion displacement member operating body 51g3 which has a rotation fulcrum 51g2 on the member main body, and a ridge-shaped protrusion displacement member link body 51g4. One end of the ridge-shaped protrusion displacement member link body 51g4 has a rotation fulcrum 51g5 on the ridge-shaped protrusion displacement member main body 51g1, and the other end of the ridge-shaped protrusion displacement member link body 51g4 has a rotation fulcrum 51g6 on the ridge-shaped protrusion displacement member operating body 51g3. With this configuration, by rotating the ridge-shaped protrusion displacement member operating body 51g3 about the rotation fulcrum 51g2, the ridge-shaped protrusion 51a can be made to protrude from the ridge-shaped protrusion sliding space 51f or the ridge-shaped protrusion 51a can be returned to the ridge-shaped protrusion sliding space 51f.

The pressing member 60C is attached to the first groove-shaped recess 11a of the first panel 11 or the second groove-shaped recess 12a of the second panel 12, thereby fixing the pipe material 6 to the first panel outer surface 11s or the second panel outer surface 12s. The pressing member 60C is used to fix a pipe material 6 having a circular cross section, such as a round steel pipe. The pressing member 60C has a ridge-shaped protrusion 61a that engages with the first groove-shaped recess 11a or the second groove-shaped recess 12a, and a pipe contact surface 62 that contacts the pipe material 6.

A ridge-shaped protrusion sliding space 61f is formed in the pressing member 60C, and a ridge-shaped protrusion displacement member 61g is disposed in the ridge-shaped protrusion sliding space 61f. The ridge-shaped protrusion 61a is formed at the end of the ridge-shaped protrusion displacement member 61g. By displacing the ridge-shaped protrusion displacement member 61g with respect to the ridge-shaped protrusion sliding space 61f, the ridge-shaped protrusion 61a protrudes from the ridge-shaped protrusion sliding space 61f. In this way, by protruding the ridge-shaped protrusion 61a from the ridge-shaped protrusion sliding space 61f, it can be engaged with the first groove-shaped recess 11a or the second groove-shaped recess 12a, making it easy to attach the pressing member 60C to the first panel 11 or the second panel 12. An elastic member 61h is disposed in the ridge-shaped protrusion sliding space 61f. The elastic member 61h has a pair of protruding pieces 61i. In a state where the ridge-shaped protrusion 61a protrudes from the ridge-shaped protrusion sliding space 61f, the pair of protruding pieces 61i of the elastic member 61h spreads out on both sides of the ridge-shaped protrusion 61a. In this way, by protruding the ridge-shaped protrusion 61a from the ridge-shaped protrusion sliding space 61f, the pair of protrusion pieces 61i spreads out, and the pair of protrusion pieces 61i can be firmly engaged with the first groove-shaped recess 11a or the second groove-shaped recess 12a.

[0120] Although explanations of the symbols will be omitted, the ridge-shaped protrusion displacement member 61g is composed of a ridge-shaped protrusion displacement member main body having the ridge-shaped protrusion 61a formed at its end, a ridge-shaped protrusion displacement member operating body having a rotation fulcrum on the member main body, and a ridge-shaped protrusion displacement member link body, similar to that described in the embodiment of Figure 34. One end of the ridge-shaped protrusion displacement member link body has a pivot point on the ridge-shaped protrusion displacement member main body, and the other end of the ridge-shaped protrusion displacement member link body has a pivot point on the ridge-shaped protrusion displacement member operating body. With this configuration, by rotating the ridge-shaped protrusion displacement member operating body about the rotation fulcrum 2, the ridge-shaped protrusion 51a can be protruded from the ridge-shaped protrusion sliding space 61f, or the ridge-shaped protrusion 61a can be returned to the ridge-shaped protrusion sliding space 61f.

The retaining member 60D is attached to the first groove-shaped recess 11a of the first panel 11 or the second groove-shaped recess 12a of the second panel 12, thereby fixing the pipe material 6 to the first panel outer surface 11s or the second panel outer surface 12s. The retaining member 60D is used to fix a pipe material 6 having a polygonal cross section, such as a square steel pipe. The pressing member 60D has a ridge-shaped protrusion 61a that engages with the first groove-shaped recess 11a or the second groove-shaped recess 12a, and a pipe contact surface 62 that contacts the pipe material 6.

[0122] The pressing member 60D according to this embodiment has ridge-shaped protrusions 61a formed thereon.

A ridge-shaped protrusion sliding space 61f is formed in the pressing member 60D, and a ridge-shaped protrusion displacement member 61g is disposed in the ridge-shaped protrusion sliding space 61f. The ridge-shaped protrusion 61a is formed at the end of the ridge-shaped protrusion displacement member 61g. By displacing the ridge-shaped protrusion displacement member 61g with respect to the ridge-shaped protrusion sliding space 61f, the ridge-shaped protrusion 61a protrudes from the ridge-shaped protrusion sliding space 61f.

[0124] A further embodiment of the panel joining method according to the present invention will now be described. FIG. 37 is a side view of the main part of a structure in a construction state, showing the panel joining method according to this embodiment. The formwork panel according to this embodiment is a panel 10 used in construction when pouring concrete, and is used by joining adjacent panels 10 together using joining members 20 instead of crosspieces.

[0125] As shown in FIG. 37, in the construction of formwork for a concrete structure, a wall body 10c is supported by beam support members 3 at the beam portion, and the beam support members 3 are held by pipe supports 4. In this embodiment, wall body 10c is a second panel used as the bottom surface. A pair of walls 10a and 10b are joined to wall body 10c. In this embodiment, the pair of walls 10a and 10b are first panels. Concrete is poured into a space 2 surrounded by the pair of walls 10a and 10b and wall body 10c. A fastening member 5 is attached to the pair of wall bodies 10a, 10b to maintain a constant distance between the pair of wall bodies 10a, 10b. The fastening member 5 is composed of a separator 5a, a pair of cones 5b, a pair of fastening member bodies 5c, and a pair of washers 5d. The walls 10a, 10b, and 10c are formed by joining multiple panels 10. Crosspieces are generally used to join the panels 10. Crosspieces are sometimes used to increase the rigidity of the panels 10, but in this embodiment, horizontal pipe members 6b are placed at predetermined intervals on the outer surfaces of the panels 10 of the wall bodies 10a and 10b, and these horizontal pipe members 6b ensure the rigidity of the panels 10. The pipe members 6 support the load applied to the panels 10 when concrete is poured. In this embodiment, the first panel is butted against the second panel perpendicularly, and the joining member 20N is disposed at the outer corner of the joint between the first panel and the second panel. A support frame member 80 is attached to the beam support member 3 that supports the second panel from below.

[0126] Figure 38 is a diagram showing the main components of Figure 37, where Figure 38(a) is an enlarged view of the main components of Figure 37, Figure 38(b) is a cross-sectional view of the frame member for the receiving material, and Figure 38(c) is a perspective view of the frame member for the receiving material. In the panel joining method according to this embodiment, a pipe material made of a steel pipe is used as the beam support member 3. The pipe material is preferably a square steel pipe, but a round steel pipe can also be used. The beam support material (pipe material) 3 is used by inserting it into a support material frame member 80. In this embodiment, the material frame member 80 is provided on a part of the beam support material (pipe material) 3, but it may also be provided over the entire length of the support material (pipe material) 3. By using pipe material made of steel pipes as the beam support material 3, sufficient strength can be maintained and the number of pipe supports 4 can be reduced. A joining member holder 91 for holding the joining member 20N is attached to the upper surface of the frame member 80 for the receiving member. A pipe support holding material 100 for holding the upper end of the pipe support 4 is attached to the underside of the support frame member 80 . A pair of upper surface protrusions 81 are formed on both longitudinal sides of the upper surface of the frame member 80 for receiving material, and a pair of lower surface protrusions 82 are formed on both longitudinal sides of the lower surface of the frame member 80 for receiving material. The joint member holder 91 is formed with a pair of locking portions 91a corresponding to the pair of upper surface protrusions 81. The joint member holder 91 can slide relative to the receiving frame member 80 with the pair of locking portions 91a locked to the pair of upper surface protrusions 81.

[0127] The pipe support holding material 100 is formed with a pair of locking portions 100a corresponding to the pair of lower surface protrusions 82. The pipe support holding material 100 can slide relative to the receiving frame member 80 with the pair of locking portions 100a locked to the pair of lower surface protrusions 82. The joint member holder 91 is formed with a joint member holder portion 91b for holding the joint member 20N. The pipe support holding material 100 is formed with a cylindrical portion 100b into which the upper end of the pipe support 4 can be inserted. When the pipe support 4 is a square steel pipe, the cylindrical portion 100b is preferably a square cylindrical portion as shown in the figure, but when the pipe support 4 is a round steel pipe, the cylindrical portion 100b is preferably a round cylindrical portion.

[0128] Figure 39 shows the state in which the beam support material, support material frame member, joint member holder, and joint member are installed, with Figure 39(a) showing the state in which the first panel and second panel are present, and Figure 39(b) showing the state in which the first panel and second panel are absent. Also, Figure 40 is a structural diagram showing the state in which the frame member for the receiving member, the joint member holding member, and the joint member are attached, and is a structural diagram seen from an angle different from Figures 40(a) and 40(b).

[0129] According to this embodiment, the joining member 20N used for the second panel that forms the bottom surface can be held by the joining member holder 80. Furthermore, according to this embodiment, sufficient strength can be maintained by using the pipe material, and the joining member holder can be attached by the support frame member. Furthermore, according to this embodiment, the pipe support holder can be attached by the support frame member. Furthermore, according to this embodiment, the position of the joint member holder can be easily adjusted, and the joint members can be easily attached. Furthermore, according to this embodiment, the position of the pipe support holding member can be easily adjusted, and the pipe support can be easily attached.

[0130] Figure 41 is a structural diagram showing the joining member shown in Figures 39 and 40, and Figure 41(b) is a structural diagram showing a state in which one side joining member and the other side joining member have been rotated by a predetermined angle compared to Figure 41(a).

[0131] The joint member 20N has a first joint member 21 on which the first ridge-shaped protrusion 21a is arranged, and a second joint member 22 on which the second ridge-shaped protrusion 22a is arranged. Although some of the components are not shown in the illustration, as in the other embodiments, a one-side ridge-shaped convex portion sliding space is formed in the one-side joining member 21, and a one-side ridge-shaped convex portion displacement member 21g is arranged in the one-side ridge-shaped convex portion sliding space. In addition, a one-side elastic member is disposed in the one-side ridge-like convex portion sliding space. The one-side elastic member has a pair of protruding pieces 21i arranged outside the one-side ridge-like convex portion sliding space.

[0132] The other-side joining member 22 has an other-side ridge-like convex portion sliding space formed therein, and an other-side ridge-like convex portion displacement member 22g is disposed in the other-side ridge-like convex portion sliding space. In addition, an other-side elastic member is disposed in the other-side ridge-like convex portion sliding space. The other-side elastic member has a pair of protruding pieces 22i disposed outside the other-side ridge-like convex portion sliding space.

[0133] The first rib-shaped protrusion 21a is formed at the end of the one-side rib-shaped protrusion displacement member 21g. Therefore, by displacing the one-side rib-shaped protrusion displacement member 21g with respect to the one-side rib-shaped protrusion sliding space, the first rib-shaped protrusion 21a protrudes from the one-side rib-shaped protrusion sliding space. When the first ridge-shaped protrusion 21a protrudes from the one-side ridge-shaped protrusion sliding space, the pair of protruding pieces 21i of the one-side elastic member spreads out on both sides of the first ridge-shaped protrusion 21a.

[0134] The second ridge-shaped protrusion 22a is formed at the end of the other-side rib-shaped protrusion displacement member 22g. Therefore, by displacing the other-side rib-shaped protrusion displacement member 22g with respect to the other-side rib-shaped protrusion sliding space, the second rib-shaped protrusion 22a protrudes from the other-side rib-shaped protrusion sliding space. When the second ridge-shaped protrusion 22a protrudes from the other-side ridge-shaped protrusion sliding space, the pair of protruding pieces 22i of the other-side elastic member spreads out on both sides of the second ridge-shaped protrusion 22a.

[0135] In this way, by protruding the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a from the one-side ridge-shaped protrusion sliding space and the other-side ridge-shaped protrusion sliding space, the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a can be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a. Furthermore, by having the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a protrude from the one-side ridge-shaped protrusion sliding space and the other-side ridge-shaped protrusion sliding space, the pair of protrusion pieces 21i, 22i spread out, and the pair of protrusion pieces 21i, 22i can firmly engage the first ridge-shaped protrusion 21a and the second ridge-shaped protrusion 22a with the first groove-shaped recess 11a and the second groove-shaped recess 12a. The one-side joining member 21 and the other-side joining member 22 are connected by a rotation shaft 25. The one-side joining member 21 and the other-side joining member 22 can be rotated by a predetermined angle by the rotation shaft 25. Therefore, the first ridge-shaped convex portion 21a and the second ridge-shaped convex portion 22a can easily be engaged with the first groove-shaped recess 11a and the second groove-shaped recess 12a.

[0136] One-side rib-shaped protrusion displacement member 21g is provided with one-side return cam member 21j, and the other-side rib-shaped protrusion displacement member 22g is provided with a other-side return cam member 22j. One-side return cam member 21j is rotatably attached to one-side rib-shaped protrusion displacement member 21g, and the other-side return cam member 22j is rotatably attached to the other-side rib-shaped protrusion displacement member 22g. By rotating one-side return cam member 21j or the other-side return cam member 22j with first rib-shaped protrusion 21a or second rib-shaped protrusion 22a protruding, the first rib-shaped protrusion 21a or second rib-shaped protrusion 22a can be returned to one-side rib-shaped protrusion sliding space 21f or the other-side rib-shaped protrusion sliding space 22f. The joint member 20N according to this embodiment is formed with a protrusion 26 that engages with the joint member holding portion 91b.

Then, as shown in FIG. 42(a), the second ridge-shaped protrusion 22a is engaged with the second groove-shaped recess 12a of the second panel 12 by pressing the other-side ridge-shaped protrusion displacement member 22g. After engaging the second ridge-shaped protrusion 22a with the second groove-shaped recess 12a, the one-side joining member 21 is rotated as shown in Figure 42(c) to abut the one-side joining member 21 against the outer surface of the first panel (wall body 10a) 11. Then, as shown in FIG. 42(d), the first ridge-shaped protrusion 21a is engaged with the first groove-shaped recess 11a of the first panel 11 by pressing the one-side ridge-shaped protrusion displacement member 21g.
