According to such a configuration, when the deformable panel is subsequently constructed from the non-curved state to the curved state, the deformed portion of the third metal plate is limited by the amount of the embossed portion and / or the opening. As a result, the deformed portion of the third metal plate is easily plastically processed, and the processing force when performing the construction from the non-curved state to the curved state can be reduced. Further, it becomes easier to hold the deformed panel in a curved state, and the stability of the shape can be improved.

There may be further provided holding means. According to such a configuration, the curved state can be stably maintained after the deformable panel is subsequently curved.

  The building panel 10 according to the present embodiment will be described. As shown in FIG. 1A, the building panel 10 of this embodiment includes a panel body 20 and a spacer 140 for holding the panel body 20 in a curved state. In the construction example shown in FIG. 1A, the spacer 140 is attached to each of the upper end and the lower end of the panel body 20.

  2A, the panel body 20 includes a first metal plate 22 (an example of a first metal plate), a second metal plate 24 (an example of a second metal plate), and a third metal plate. A metal plate 26 (an example of a core material and an example of a third metal plate).

  The first metal plate 22 is a single plate material made of a metal material. For the first metal plate 22, for example, a steel plate for construction is used. The 1st metal plate 22 is arrange | positioned at the surface side or back surface side of a structure. The first metal plate 22 is configured to be able to bend in the x direction, and is in a curved state (curved state) after the construction (the state shown in FIG. 2A (a)). Here, “curve in the x direction” means that when the surface of the first metal plate 22 is scanned in the x direction, the z coordinate (position in the thickness direction) of the scanning point changes. Means. Note that even if the surface of the first metal plate 22 is scanned in the y direction, the z coordinate of the scanning point does not change, so the first metal plate 22 is not curved in the y direction.

  The 2nd metal plate 24 is comprised similarly to the 1st metal plate 22, and is one board | plate material formed with the metal material. The dimension of the 2nd metal plate 24 and the dimension of the 1st metal plate 22 are made the same. For the second metal plate 24, for example, a steel plate for construction is used. The 2nd metal plate 24 is arrange | positioned facing the 1st metal plate 22, and is arrange | positioned at the back surface side or surface side of a structure. The second metal plate 24 is configured to be bendable in the x direction, and is in a state of being bent in the x direction (curved state) after construction.

  The third metal plate 26 is a single plate material made of a metal material. For the third metal plate 26, for example, a steel plate for construction is used. The third metal plate 26 is disposed between the first metal plate 22 and the second metal plate 24, and connects the first metal plate 22 and the second metal plate 24. As shown in FIGS. 2A and 3A, the third metal plate 26 is bent at a plurality of locations, and is formed in a rectangular wave shape when viewed in the xz cross section. That is, the third metal plate 26 is bent at a plurality of locations spaced in the x direction. A ridge line 29 formed by bending the third metal plate 26 extends in the y direction. Since the third metal plate 26 is bent so that the ridge line 29 extends in the y direction, the third metal plate 26 can be bent in the x direction. The dimension in the xy direction of the third metal plate 26 is substantially the same as the dimension in the xy direction of the first metal plate 22 and the second metal plate 24 in a bent state. Specifically, each of the dimension in the x direction and the dimension in the y direction of the third metal plate 26 is slightly shorter than the corresponding dimension of the first metal plate 22 and the second metal plate 24.

  Here, the third metal plate 26 is bent as described above, so that a plurality of first portions 28 fixed to the first metal plate 22 and a plurality of first portions fixed to the second metal plate 24 are obtained. The second portion 30 includes a plurality of third portions 32 that connect the first portion 28 and the second portion 30.

  The plurality of first portions 28 are formed in a rectangular shape in plan view, and are arranged at equal intervals with an interval in the x direction. The first portion 28 has the same dimension in the x direction. Since the first portion 28 is fixed to the first metal plate 22, when the panel body 20 is changed from the non-curved state to the curved state, the first portion 28 is relatively disposed between the first metal plate 22 and the first portion 28. There is no change in position.

  The plurality of second portions 30 are also formed in a rectangular shape in plan view, and are arranged at equal intervals with an interval in the x direction by the length of the first portion 28. The dimensions of the second portion 30 in the x direction are the same, and are the same as the dimensions of the first portion 28 in the x direction. Since the second portion 30 is fixed to the second metal plate 24, when the panel body 20 is changed from the non-curved state to the curved state, the second portion 30 is relatively disposed between the second metal plate 24 and the second portion 30. There is no change in position.

  The plurality of third portions 32 are formed in a rectangular shape in plan view, and are arranged at intervals in the x direction by the lengths of the first portion 28 and the second portion 30. Since the lengths of the first portion 28 and the second portion 30 in the x direction are the same, the plurality of third portions 32 are arranged at equal intervals in the x direction. The dimensions of the third portion 32 in the z direction are the same. One end of the third portion 32 is connected to the first portion 28, and the other end of the third portion 32 is connected to the second portion 30. When the panel body 20 is in a non-curved state, the angle formed by the third portion 32 and the first portion 28 is 90 °, and the angle formed by the third portion 32 and the second portion 30 is 90 °. ing. For this reason, when the panel main body 20 is viewed in the xz section, the space 38 formed by the first portion 28 of the third metal plate 26, the third portions 32 and 32, and the second metal plate 24 is rectangular ( FIG. 4 (a)). Similarly, the space 38 formed by the second portion 30 of the third metal plate 26, the third portions 32 and 32, and the first metal plate 22 is rectangular (FIG. 4A). Further, as will be described in detail later, when the panel body 20 is changed from the non-curved state to the curved state, the plurality of third portions 32 each maintain parallelism. The first portion 28, the second portion 30, and the third portion 32 have the same y-direction dimensions.

  Next, the spacer 140 will be described. As shown in FIG. 2A (b), the spacer 140 is formed of a single plate material (for example, a steel plate for construction) formed of a metal material. The spacer 140 has a base end portion 148 and a plurality of insertion portions 142 arranged along one side of the base end portion 148. A slit 144 is formed between adjacent insertion portions 142. The width of the slit 144 gradually increases as the opening portion 146 moves away from the base end portion 148.

  Each of the insertion portions 142 is inserted into the space 38 of the panel body 20. For example, as shown in FIG. 1A, the insertion portion 142 of the spacer 140 shown on the upper side is inserted into the space 38 from the upper end surface side of the panel body 20, and the insertion portion 142 of the spacer 140 shown on the lower side is below the panel body 20. It is inserted into the space 38 from the end face side.

As shown in FIG. 2A, when the insertion portion 142 is inserted into the space 38 of the panel main body 20, the insertion portion 142 contacts the panel main body 20 at a corner portion on the diagonal line of the space 38. Specifically, a corner portion formed by the first portion 28 (or the second portion 30) and the third portion 32, a corner portion formed by the third portion 32 and the first metal plate 22, or a third portion. It abuts at any one of the corner portions formed by the portion 32 and the second metal plate 24. The insertion portion 142 is inserted after the panel main body 20 is bent. Since the insertion portion 142 contacts the panel main body 20 at the corner portion opposite to the space 38, the insertion portion 142 functions as a brace, and the curved state of the panel main body 20 is maintained by the insertion portion 142. 2A, when the panel body 20 is in a curved state, the lengths of the diagonal lines of the spaces 38a, 38b, 38c,. Therefore, the dimensions l ₁ , l ₂ , l ₃ ,... In the x direction of the insertion portions 42 a and 42 b are adjusted according to the curved state of the panel body 20. Further, since the spacer 140 formed from one plate material is inserted into the space 38 of the panel main body 20, when the spacer 140 is inserted into the panel main body 20, the spacer 140 is bent into a mountain / valley at the adjacent insertion portion 142. It is assumed that Since the width of the opening 146 of the slit 144 is formed so as to gradually widen, the insertion portion 142 can be smoothly inserted into the space 38 of the panel body 20. In consideration of workability, the connecting member 40 may be formed by separating the connecting members 40 from each of the members 42a and 42b. In this case, each of the separated 42a and 42b is inserted into the space 38 one by one.

  Next, the procedure at the time of manufacturing and constructing the building panel 10 described above will be described. In the present embodiment, the panel body 20 is manufactured in a non-curved state. That is, the first metal plate 22 and the second metal plate 24 are not curved, and the third metal plate 26 is only bent. For this reason, the cross-sectional shape (xz cross section) of the space 38 of the panel main body 20 is a rectangular shape (state of Fig.4 (a)). On the other hand, the spacer 140 must adjust the dimension of the insertion portion 142 in the x direction in accordance with the shape of the panel body 20 when it is in a curved state. Therefore, the slit 144 is not formed so that the dimension of the insertion portion 142 in the x direction can be adjusted at the construction site.

  When constructing the building panel 10, first, the panel body 20 is bent in the x direction so as to have a desired shape. Here, since each dimension of the 1st part 28 of the 3rd metal plate 26, the 2nd part 30, and the 3rd part 32 is comprised as mentioned above, the 1st metal plate 22 and the 2nd metal plate 24 are curved. If it does, the 3rd metal plate 26 will curve according to it. That is, even when the first metal plate 22 and the second metal plate 24 are curved, the state in which the space 38 of the panel body 20 is a parallelogram (the plurality of third portions 32 are parallel to each other) is maintained. For this reason, the shape of each space 38 of the panel main body 20 changes according to the curved shape of the 1st metal plate 22 and the 2nd metal plate 24 (state of FIG.4 (b)). Accordingly, the third metal plate 26 is bent according to the bending state of the first metal plate 22 and the second metal plate 24, and the panel body 20 is bent into a desired shape.

  When the panel body 20 is bent, the insertion portion 142 of the spacer 140 is inserted into the panel body 20. Here, the dimension of the insertion portion 142 in the x direction must be adjusted according to the shape of the panel body 20 when it is in a curved state. For this reason, the actual position of the slit 144 is adjusted in accordance with the curved shape of the panel body 20 at the construction site, and the slit 144 is actually formed in the spacer 140. Next, the insertion portion 142 of the spacer 140 is inserted into the space 38 of the panel body 20 to determine the curved shape of the panel body 20.

  As is clear from the above description, in the building panel 10 of this embodiment, the non-curved panel body 20 can be manufactured and deformed into a curved shape at the construction site. That is, the panel body 20 can be post-formed (later modified). For this reason, high accuracy is not required for the manufacture of the panel body 20, and the panel body 20 can be easily adjusted to a desired curved shape at the construction site.

  Moreover, since the panel main body 20 can be post-formed into a desired curved shape, the panel main body 20 can be factory-produced with a unified standard. For this reason, it can respond to the request | requirement of various construction sites, reducing manufacturing cost. Moreover, since the panel main body 20 can be manufactured according to a unified standard, the mechanical characteristics of the panel main body 20 are stabilized, and accurate performance prediction of the panel main body 20 becomes possible.

  In addition, in the panel main body 20 which concerns on said Example, you may use the 3rd metal plate 26 shown in FIG. In the third metal plate 26 shown in FIG. 5, an opening 34 is formed at the connection portion between the third portion 32 and the first portion 28 and at the connection portion between the third portion 32 and the second portion 30. A plurality of openings 34 are formed at intervals along the ridgeline 29. By forming the opening 34 in the third metal plate 26, the processing force when the panel body 20 is formed into a curved shape can be reduced. That is, when the opening 34 is formed in the third metal plate 26, when the panel body 20 is deformed into a curved shape, the deformation portion of the third metal plate 26 is changed to a portion where the opening 34 is not formed. Limited. Thereby, the processing force at the time of making the panel main body 20 into a curved shape can be reduced. Moreover, since the deformation | transformation site | part of the 3rd metal plate 26 is limited, it becomes easy to produce plastic working in the deformation | transformation site | part. As a result, the curved shape of the panel body 20 can be stabilized.

  Furthermore, in the panel main body 20 according to the above embodiment, the third metal plate 26 shown in FIG. 6 may be used. In the third metal plate 26 shown in FIG. 6, a plurality of embossed portions 36 are formed in the third portion 32. A plurality of embossed portions 36 are formed at intervals in the y direction. By forming the embossed portion 36 on the third metal plate 26, the deformed portion of the third metal plate 26 is further limited, and the reduction of the processing force at the time of molding and the stabilization of the curved shape of the panel body 20 are further improved. be able to.

  In the above-described embodiment, the curved portion of the panel body 20 is maintained by inserting the insertion portion 142 of the spacer 140 into the space 38 of the panel body 20, but the present invention has such a form. Not limited. For example, as shown in FIG. 7, the corner portions of the space 38 that are opposite to each other may be connected and fixed by fixing members (for example, screws, wires, etc.) 41. Even if it does in this way, the fixing member 41 fulfill | performs the bracing function and the curved shape of the panel main body 20 can be maintained. Further, as shown in FIG. 8, the curved shape of the panel body 20 may be maintained by plastically deforming the panel body 20 at each corner portion 49 of the space 38.

  Moreover, in the Example mentioned above, although it was the example which constructs the panel main body 20 single-piece | unit, you may make it construct by connecting the some panel main body 20. FIG. For example, in the construction example shown in FIG. 1B, one structure (for example, a wall, a roof, etc.) is formed by connecting the two panel bodies 20 with the connecting member 40. Since the panel main body 20 is the same as the panel main body 20 of the first embodiment, the connecting member 40 will be described here.

  As shown in FIG. 2B (b), the connecting member 40 is formed of a single plate material (for example, a steel plate for construction) formed of a metal material. The connecting member 40 has insertion portions 42a and 42b and a central portion 48 located between the insertion portions 42a and 42b. A plurality of insertion portions 42 a are arranged along one side of the central portion 48, and a plurality of insertion portions 42 b are arranged along the other side of the central portion 48. Slits 44a and 44b are formed between the adjacent insertion portions 42a and 42b.

  Each of the insertion portions 42 a and 42 b is inserted into the space 38 of the panel body 20. As shown in FIG. 1, the insertion portion 42a is inserted into the space 38 from the upper end surface side of the panel main body 20 located on the lower side in the drawing, and the insertion portion 42b is inserted from the lower end surface side of the panel main body 20 located on the upper side in the drawing. It is inserted into the space 38. By inserting the insertion portions 42a and 42b of the connecting member 40 into the spaces 38 of the panel main bodies 20 and 20, the two panel main bodies 20 are connected in the vertical direction. Thereby, the two panel main bodies 20 can be connected.

  In the panel main body 20 of Example 1 described above, the third metal plate 26 formed in a rectangular wave shape is used as the core material disposed between the first metal plate 22 and the second metal plate 24. Is not limited to such a form. As shown in FIGS. 9 and 10, in the panel main body 50 of the second embodiment, a core material 62 composed of a plurality of resin plates 56, 58, 60 is disposed between the first metal plate 52 and the second metal plate 54. The The core material 62 is formed of a third resin plate 60, a second resin plate 58 laminated on the third resin plate 60, and a first resin plate 56 laminated on the second resin plate 58. The first metal plate 52 and the first resin plate 56, the first resin plate 56 and the second resin plate 58, the second resin plate 58 and the third resin plate 60, the third resin plate 60 and the second metal plate 54, respectively. Is partially fixed. For this reason, when the panel main body 50 is formed in a curved shape, slip occurs on these contact surfaces. The first metal plate 52 and the first resin plate 56, the first resin plate 56 and the second resin plate 58, the second resin plate 58 and the third resin plate 60, the third resin plate 60 and the second metal plate 54, respectively. As a result of slippage at the contact surface, the panel body 50 can be deformed into a curved shape. As shown in FIG. 10, the curved shape of the panel main body 50 is held by holding members 64 a and 64 b arranged at both ends of the panel main body 50. Engaging grooves 66a and 66b are formed in the holding members 64a and 64b, and the first metal plate 52, the first resin plate 56, the second resin plate 58, and the third resin of the panel body 50 are formed in the engaging grooves 66a and 66b. The plate and the second metal plate 54 engage. As a result, the curved shape of the panel body 50 is maintained. The plurality of resin plates 56, 58, and 60 can be formed of, for example, a foamable heat insulating material. When a heat insulating material is used for the plurality of resin plates 56, 58, 60, the panel body 50 can be provided with heat insulating performance.

  In the panel main body 50 of the above-described second embodiment, a configuration in which the resin plates 56, 58, and 60 are partially fixed so as to slip is adopted, but the present invention is limited to such a form. Absent. For example, as shown in FIG. 11, an intermediate layer 68 that is easily deformed at the time of curve forming may be disposed between two layers 70 and 72 that are desired to cause slippage. That is, the mechanical strength of the intermediate layer 68 is made smaller than the mechanical strength of the layers 70 and 72. Specifically, for example, the layers 70 and 72 are hard resin layers (for example, a hard urethane layer), and the intermediate layer 68 is a soft resin layer (for example, a soft urethane layer). Then, the layer 70 and the intermediate layer 68 are fixed (adhered) as a whole, and the intermediate layer 68 and the layer 72 are fixed (adhered) as a whole. According to such a configuration, when the panel body is curved, the intermediate layer 68 is deformed from the state shown in FIG. 11A to the state shown in FIG. 11B, and a slip occurs between the layers 70 and 72.
