  • the base material 30 B is attached to the support member 20 B in a state in which the protruding piece 25 of the support member 20 B is fitted into the groove 37 provided in the base material 30 B. Since the position of the base material 30 B in the longitudinal direction D 2 is determined by this fitting structure, the work for the worker to adjust the position of the base material 30 B in the longitudinal direction D 2 can be omitted. This makes it possible to simplify the work of attaching the base material 30 B.
  • the base materials 30 C and 30 D are attached to the support members 20 C, 20 D and 20 E in a state in which the base materials 30 C and 30 D are fitted into the missing portions 25 a provided in the protruding pieces 25 of the support members 20 C, 20 D and 20 E. Since the positions of the base materials 30 C and 30 D in the longitudinal direction D 2 are determined by these fitting structures, the work for the worker to adjust the position of the base materials 30 C and 30 D in the longitudinal direction D 2 can be omitted. This makes it possible to simplify the work of attaching the base materials 30 C and 30 D.
  • the base material 30 can be systematically attached to the support member 20 .
  • the leg 12 A of the panel material 10 is marked with the mark M. This makes it possible to indicate the direction in which the panel material 10 is attached by the direction (top, bottom, left and right) of the mark M in the work instruction sheet. Therefore, the worker can easily judge the direction in which the panel material 10 is attached, so that the workability of the panel material 10 can be improved.
  • the support members 20 A to 20 E are mounted on the outer wall 2
  • the base materials 30 A to 30 D are mounted on the support members 20 A to 20 E.
  • the plurality of panel materials 10 are attached to the base materials 30 A to 30 D. Therefore, the panel material 10 can be attached without influence of the shape of the outer wall 2 .
  • the support members 20 C to 20 E are arranged in the longitudinal direction D 2 orthogonal to a direction (lateral direction D 1 ) in which the siding panel 5 extends, and are attached across two siding panels 5 adjacent to each other in the longitudinal direction D 2 .
  • This configuration makes it difficult for the female end portion 52 of the upper siding panel 5 and the male end portion 51 of the lower siding panel 5 to disengaged from each other. As a result, the wind pressure resistance performance of the outer wall 2 can be improved.
  • the panel material 10 at the left end is positioned by bringing the left end of the panel material 10 into contact with (the locking piece 45 of) the crown molding 40 C.
  • the panel material 10 other than the left end is positioned by bringing the left end of the panel material 10 into contact with the right end of the panel material 10 located on the left side of the panel material 10 .
  • This configuration makes it possible to reduce the gap (joint) between the two panel materials 10 adjacent to each other in the lateral direction D 1 .
  • the protrusions 34 of the base materials 30 C and 30 D are inserted through the insertion holes 12 c and 12 d provided in the leg 12 of the lower panel material 10 and the insertion holes 12 c and 12 d provided in the leg 12 of the upper panel material 10 , and the legs 12 of the two panel materials 10 adjacent to each other in the longitudinal direction D 2 are attached to the base materials 30 C and 30 D.
  • This configuration makes it possible to reduce the gap (joint) between the two panel materials 10 adjacent to each other in the longitudinal direction D 2 .
  • the decorative structure, the panel material, and the method for constructing the decorative structure according to the present disclosure are not limited to the above-described embodiments.
  • the outer wall 2 on which the decorative structure 1 is installed is configured by attaching a plurality of siding panels 5 so as to extend in the horizontal direction, but the outer wall 2 is not limited to this configuration.
  • the outer wall 2 on which the decorative structure 1 is installed may be configured by attaching a plurality of siding panels 5 so as to extend in the vertical direction.
  • the decorative structure 1 may be provided by being rotated 90 degrees clockwise.
  • the decorative structure 1 may be installed on not only the outer wall but also the inner wall.
  • the decorative shape of the surface 11 a may be a shape inclined from one side to the other side among a pair of mutually facing sides of the outer edge portion 11 b.
  • the decorative structure 1 includes nine panel materials 10 , but the number of panel materials 10 can be changed depending on the size of the desired decorative structure 1 .
  • the lengths of the support members 20 A and 20 B, the base materials 30 A to 30 D, and the crown moldings 40 A and 40 B are adjusted depending on the number of the panel materials 10 in the lateral direction D 1 .
  • the lengths of the support members 20 C to 20 E and the crown moldings 40 C and 40 D, and the number of the base materials 30 are adjusted depending on the number of the panel materials 10 in the longitudinal direction D 2 .
  • the support members 20 A to 20 E have the same shape but may have different shapes.
  • the base materials 30 A to 30 D have the same shape but may have different shapes.
  • the base material 30 A may include at least the projection 35 which is contact with the protruding piece 25 of the support member 20 A in the longitudinal direction D 2 , and the groove 37 may not be provided.
  • At least the groove 37 which is fitted into the protruding piece 25 of the support member 20 B may be provided in the base material 30 B, and the base material 30 B may not include the bulge 36 .
  • the base materials 30 C and 30 D may have a shape that fits into the missing portions 25 a provided in the support members 20 C to 20 E, and the groove 37 may not be provided.
  • the crown moldings 40 A to 40 D have the same shape, but may have different shapes.
