The protrusion 35 protrudes to the same plane as the surface 31b of the base 31. A groove 37 is defined by the protruding portion 35, the base 31, and the connecting portion 33. The convex portion 36 is provided on the surface 32b and extends over the entire length of the base material 30 in the longitudinal direction. The convex portion 36 and the protrusion 35 form a right angle, and the convex portion 36 and the protrusion 35 define a concave portion 38 .

In the example shown in FIG. 2, four base materials 30 extend in the horizontal direction D1 and are provided parallel to each other at predetermined intervals in the vertical direction D2. When distinguishing between these, the base material 30 located at one end (upper end) in the vertical direction D2 is referred to as the base material 30A (second base material), and the base material 30 located at the other end (lower end) in the vertical direction D2 is referred to as a base material 30A (second base material). is referred to as base material 30B (first base material), and the base materials 30 located between base material 30A and base material 30B are referred to as base material 30C (third base material), and base material 30D (third base material) in order from the top. (See Figure 14, etc.).

The base material 30A is arranged so that the surface 31b faces the mounting surface 21a and the projection 34 protrudes downward, and the other base materials 30B, 30C, and 30D are arranged so that the surface 31b faces the mounting surface 21a. They are arranged so that they face each other and the projections 34 protrude upward. The base material 30A overlaps the support member 20A when viewed from the direction D3. The base material 30B overlaps the support member 20B when viewed from the direction D3. The base materials 30C, 30D are provided to intersect with the support members 20C, 20E, 20D. The locking structure between the support member 20 and the base material 30 will be described in detail in the description of the construction method of the decorative structure 1.

The circumferential edge 40 is a member for hiding the edge. The material forming the circumferential edge 40 is, for example, metal such as aluminum and titanium. The circumferential edge 40 is produced, for example, by extrusion molding. The leg portion 12 of the panel material 10, the support member 20, and the base material 30 are covered and hidden by the circumferential edge 40.

With further reference to FIG. 9, the circumferential edge 40 will be described in detail. FIG. 9 is a perspective view showing the circumferential edge shown in FIG. 1. As shown in FIG. 9, the peripheral edge 40 includes a top plate 41, side plates 42, 43, a bottom plate 44, and a locking piece 45.

The upper plate 41 is a plate-shaped portion that covers the edge. The upper plate 41 is provided along the longitudinal direction of the circumferential edge 40 over the entire length of the circumferential edge 40 . The side plates 42 and 43 are plate-shaped portions that support the upper plate 41. The side plates 42 and 43 are provided over the entire length of the circumferential edge 40 along the longitudinal direction of the circumferential edge 40. The side plates 42 and 43 are provided so as to face each other with the upper plate 41 in between, and extend in a direction intersecting the upper plate 41. One end of the side plate 42 is connected to one end of the upper plate 41 in the lateral direction. One end of the side plate 43 is connected to the other end of the upper plate 41 in the lateral direction.

The bottom plate 44 is a part for fixing the peripheral edge 40 to the support member 20. The bottom plate 44 is provided over the entire length of the circumferential edge 40 along the longitudinal direction of the circumferential edge 40 . One end of the bottom plate 44 is connected to the other end of the side plate 42, and the bottom plate 44 extends substantially parallel to the top plate 41 from the other end of the side plate 42 in a direction away from the top plate 41. The peripheral edge 40 is fixed to the side plate 23 of the support member 20 by driving a fixing member 64 such as a screw into the bottom plate 44 (see FIGS. 18 and 21). The locking piece 45 is connected to the other end of the side plate 23 and protrudes inward from the other end of the side plate 23. The locking piece 45 is provided over the entire length of the circumferential edge 40 along the longitudinal direction of the circumferential edge 40 . The locking piece 45 abuts against the leg portion 12 of the panel material 10.

In the example shown in FIG. 1, four circumferential edges 40 are located at the upper end, the lower end, and both left and right ends of the decorative structure 1, forming a frame of the decorative structure 1. When distinguishing these, the upper edge 40, the lower edge 40, the left edge 40, and the right edge 40 are defined as edges 40A, 40B, 40C, and 40D, respectively. (See FIG. 18, FIG. 21, etc.). The peripheral edges 40A to 40D are arranged such that the bottom plate 44 is placed on the side plate 23 of the support members 20A to 20D, respectively, and the locking piece 45 is in contact with the leg portion 12.

Note that the material of the fixing members 61 to 65 is, for example, stainless steel. The fixing members 61 to 65 may be subjected to a highly corrosion-resistant surface treatment. In order to prevent rainwater from entering, fixing members with packing may be used as the fixing members 61 to 65. The packing is made of, for example, EPDM (ethylene propylene diene rubber).

Next, a method for constructing the decorative structure 1 will be described with reference to FIGS. 10 to 21. FIG. 10 is a process diagram showing a method of constructing the decorative structure shown in FIG. 1. FIG. 11 is a diagram for explaining the marking process shown in FIG. 10.

FIG. 20 is a diagram for explaining the process of attaching the panel material shown in FIG. 10. FIG. 21 is a diagram for explaining the process of attaching the upper edge shown in FIG. 10.

As shown in FIG. 10, first, a marking step S1 is performed. In the marking step S1, a broken line L1 is drawn on the outer wall 2 at a position where the decorative structure 1 is to be attached. The position where the decorative structure 1 is attached is, for example, the outer periphery of the decorative structure 1. The outer circumference of the decorative structure 1 is determined according to the number of panel members 10 to be constructed in the horizontal direction D1 and the vertical direction D2. In the marking step S1, a broken line L2 is further drawn on the outer wall 2 to indicate the position of the furrow 4.

Subsequently, a step S2 of attaching the support member 20 is performed. In the step S2 of attaching the support members 20, the support members 20A to 20D are placed on the outer wall 2 along the broken line L1. Specifically, in the support members 20A to 20D, the bottom plate 24 faces the center of the frame surrounded by the broken line L1, the protruding piece 25 protrudes outward (the side opposite to the outer wall 2), and the other end of the side plate 23 are arranged along the broken line L1. Further, a support member 20E is arranged on the outer wall 2 along the broken line L2. Specifically, the support member 20E is arranged so that the protruding piece 25 protrudes outward (to the side opposite to the outer wall 2) and the tip of the bottom plate 24 runs along the broken line L2.

Then, each support member 20 is fixed to the outer wall 2 by a fixing member 61 and a fixing member 62. Each support member 20 is fixed by a fixing member 61 or a fixing member 62, for example, at three locations along the longitudinal direction. A fixing member 61 is used for the bottom plate 24 located on the furring 4, and a fixing member 62 shorter than the fixing member 61 is used for the bottom plate 24 not located on the furring 4. Note that the fixing members 61, 62 are driven in with their tips aligned with the grooves 24a. Thereby, the fixing member 61 penetrates the bottom plate 24, the siding panel 5, and the furring 4, and the fixing member 62 penetrates the bottom plate 24 and sticks into the siding panel 5.

The support members 20A and 20B are arranged astride the two furrows 4 that are adjacent to each other in the lateral direction D1. The support members 20A, 20B are fixed by a fixing member 61 on the two furrings 4, and fixed by a fixing member 62 at the right end. The support members 20C to 20E are arranged astride two siding panels 5 that are adjacent to each other in the vertical direction D2. The support members 20C and 20E are fixed by fixing members 61 at both ends and near the center in the longitudinal direction D2. The support member 20D is fixed by a fixing member 62 at both ends and near the center in the vertical direction D2. At this time, fixing members 61 and 62 are driven into the center of the supporting members 20C to 20E near the male end 51 of the siding panel 5 so as not to impede the followability of the outer wall 2.

Subsequently, a step S3 of attaching the base material 30 is performed. In the base material 30 attachment step S3, a plurality of base materials 30 are attached so that each base material 30 extends in the horizontal direction D1 and is arranged in parallel with each other at predetermined intervals in the vertical direction D2. Specifically, the base material 30A is attached to the support member 20A. More specifically, as shown in FIG. 15, the base 31 of the base material 30A is placed on top of the upper plate 21 of the support member 20A so that the projection 34 projects downward. Ru. At this time, the protrusion 35 of the base material 30A is pressed against the protrusion piece 25 of the support member 20A from below, and the protrusion piece 25 of the support member 20A is fitted into the recess 38 of the base material 30A. The base material 30A is fixed to the upper plate 21 of the support member 20A by fixing members 63, for example, at three locations along the longitudinal direction.

Base material 30B is attached to support member 20B. More specifically, as shown in FIG. 16, the base 31 of the base material 30B is placed on the upper plate 21 of the support member 20B so that the projection 34 projects upward. At this time, the base 31 of the base material 30B is superimposed and placed on the upper plate 21 of the support member 20B while the protruding piece 25 of the support member 20B is inserted into the groove 37 of the base material 30B. The base material 30B is fixed to the upper plate 21 of the support member 20B by fixing members 63, for example, at three locations along the longitudinal direction.

The base materials 30C and 30D are attached across the support members 20C to 20E. More specifically, as shown in FIG. 17, the bases 31 of the base materials 30C and 30D are placed astride the upper plate 21 of the support members 20C to 20E so that the projections 34 protrude upward. be placed. At this time, the bases 31 and protrusions 35 of the base materials 30C and 30D are fitted into the missing parts 25a of the support members 20C to 20E, and the grooves 31d of the base materials 30C and 30D are connected to the top plate 21 and side plate 22 of the support member 20C. The positions of the base materials 30C and 30D in the lateral direction D1 are adjusted so as to overlap the corners formed by the base materials 30C and 30D. The base materials 30C and 30D are fixed to the upper plate 21 of each support member 20 by the fixing member 63 on the upper plate 21 of the support members 20C to 20E.

Note that the fixing member 63 is driven in with the tip of the fixing member 63 aligned with the groove 31c. Thereby, the fixing member 63 penetrates the base 31 and the upper plate 21.

Subsequently, a step S4 for attaching the circumferential edges 40 (circular edges 40B to 40D) is performed. In the step S4 of attaching the circumferential edges 40, the circumferential edges 40B to 40D are attached. Specifically, the circumferential edges 40B to 40D are arranged such that the bottom plate 44 is overlapped with the side plates 23 of the support members 20B, 20C, and 20D, and the locking pieces 45 of the circumferential edges 40B to 40D form a U-shape. be done. The circumferential edges 40B to 40D are respectively fixed to the side plates 23 of the support members 20B, 20C, and 20D by fixing members 64 near both ends in the longitudinal direction of each circumferential edge 40. The fixing member 64 passes through the bottom plate 44 and the side plates 23.

Subsequently, a step S5 of attaching the panel material 10 is performed. In the panel material 10 attachment process S5, each panel material 10 is attached to two base materials 30 adjacent to each other in the vertical direction D2 among the plurality of base materials 30. Each panel material 10 is attached to the base material 30 by inserting the protrusion 34 of the base material 30 into the insertion hole 12c, 12d provided in at least one of the four legs 12. It is attached. For example, in the work instruction, the construction direction of the panel material 10 is indicated by the direction of the marking M (up, down, left, and right). For example, when the stamp M indicates the bottom, the worker adjusts the construction direction of the panel material 10 so that the leg portion 12A is located at the bottom.

Specifically, as shown in FIG. 19, the lower left panel material 10 is first attached to the base material 30D and the base material 30B. Specifically, the first and second protrusions 34 from the left end of the base material 30B are inserted into the insertion holes 12c and 12d of the leg 12 located below among the four legs 12, and the four legs The first and second protrusions 34 from the left end of the base material 30D are inserted into the insertion holes 12c and 12d of the leg part 12 located above the part 12. As a result, the through hole 12e of the upper leg portion 12 and the first through hole 32e from the left end of the base material 30D overlap in the vertical direction D2, so the fixing member 65 is inserted through the through hole 12e, and the through hole 32e is screwed into the

Here, the distance in the vertical direction D2 between the surface 32a of the mounting plate 32 of the base material 30B and the surface 32a of the mounting plate 32 of the base material 30D is longer than the distance between the mutually facing leg parts 12 of the panel material 10. It is about 12 times thicker. In this configuration, the upper leg portion 12 fits into the constriction 34a of the protrusion 34 of the base material 30D. At the constriction 34a, there is a slight space between the protrusion 34 and the periphery of the insertion holes 12c, 12d, but the leg 12 is fixed by the fixing member 65. On the other hand, the leg portion 12 located below does not fit into the constriction 34a of the protrusion 34 of the base material 30B, but is located above the constriction 34a. In this position, there is almost no space between the projection 34 and the periphery of the insertion holes 12c, 12d, and movement of the leg 12 is further suppressed by the narrowed portions 12g, 12h. Therefore, even if the leg portion 12 located below is not fixed to the base material 30B by the fixing member, the possibility that its position will shift is reduced.

The lengths of the insertion holes 12c and 12d in the lateral direction D1 are larger than the length of the projection 34 in the lateral direction D1, and the through hole 12e is a long hole extending in the lateral direction D1. Therefore, the position of the panel material 10 in the lateral direction D1 can be finely adjusted before the leg portion 12 located above is fixed to the base material 30B. Here, the panel material 10 is positioned by abutting the left end of the panel material 10 against (the locking piece 45 of) the circumferential edge 40C. Subsequently, panel members 10 are sequentially attached to the right side of the attached panel members 10 by the same procedure.

Further, the second panel material 10 from the bottom is attached to the base material 30C and the base material 30D. Panel members 10 are similarly attached to the base material 30C and the base material 30D in order from the left end. Specifically, the first and second projections 34 from the left end of the base material 30D are inserted into the insertion holes 12c and 12d of the leg 12 located below among the four legs 12, and the four legs The first and second protrusions 34 from the left end of the base material 30C are inserted into the insertion holes 12c and 12d of the leg part 12 located above the part 12. At this time, the head of the fixing member 65 used to fix the lower panel material 10 is inserted into the recess 12f of the leg portion 12 located below. As a result, the through hole 12e of the upper leg portion 12 and the first through hole 32e from the left end of the base material 30C overlap in the vertical direction D2, so the fixing member 65 is inserted through the through hole 12e, and the through hole 32e is screwed into the

Here, the distance in the vertical direction D2 between the surface 32a of the mounting plate 32 of the base material 30C and the surface 32a of the mounting plate 32 of the base material 30D is longer than the distance between the mutually facing leg parts 12 of the panel material 10. It is about 12 times thicker. In this configuration, the upper leg portion 12 fits into the constriction 34a of the protrusion 34 of the base material 30C. On the other hand, since the legs 12 of the lower panel material 10 are already fitted into the constrictions 34a of the protrusions 34 of the base material 30D, the legs 12 located below fit into the constrictions 34a of the protrusions 34 of the base material 30D. It does not fit into the constriction 34a, but is located above the constriction 34a. In this position, there is almost no space between the projection 34 and the periphery of the insertion holes 12c, 12d, and movement of the leg 12 is further suppressed by the narrowed portions 12g, 12h. Therefore, even if the leg portion 12 located below is not fixed to the base material 30D by the fixing member, the possibility that its position will shift is reduced.

Then, the panel material 10 is positioned by abutting the left end of the panel material 10 against (the locking piece 45 of) the circumferential edge 40C. Subsequently, panel members 10 are sequentially attached to the right side of the attached panel members 10 by the same procedure.

Furthermore, the uppermost panel material 10 is attached to the base material 30A and the base material 30C. Panel materials 10 are also attached to the base material 30A and the base material 30C in order from the left end. Specifically, the first and second projections 34 from the left end of the base material 30C are inserted into the insertion holes 12c and 12d of the leg 12 located below among the four legs 12, and the four legs The upper leg portion 12 of the portion 12 is placed on the surface 32b of the mounting plate 32 of the base material 30A. At this time, the head of the fixing member 65 used to fix the lower panel material 10 is inserted into the recess 12f of the leg portion 12 located below. As a result, the through hole 12a of the upper leg 12 and the first through hole 32d from the left end of the base material 30A overlap in the vertical direction D2, and the through hole 12b of the upper leg 12 and the first through hole 32d from the left end of the base material 30A overlap. The second through hole 32c from the left overlaps in the vertical direction D2. Therefore, the fixing member 65 is inserted through the through holes 12a and 12b, respectively, and screwed into the through holes 32d and 32c.

Here, the distance in the vertical direction D2 between the surface 32b of the mounting plate 32 of the base material 30A and the surface 32a of the mounting plate 32 of the base material 30C is longer than the distance between the mutually facing leg parts 12 of the panel material 10. It is about 12 times thicker. Since the legs 12 of the lower panel material 10 are already fitted into the constrictions 34a of the protrusions 34 of the base material 30C, the legs 12 located below do not fit into the constrictions 34a of the protrusions 34 of the base material 30C. It does not fit in and is located above the constriction 34a. In this position, there is almost no space between the projection 34 and the periphery of the insertion holes 12c, 12d, and movement of the leg 12 is further suppressed by the narrowed portions 12g, 12h. Therefore, even if the leg portion 12 located below is not fixed to the base material 30C by the fixing member, the possibility that its position will shift is reduced.

The through holes 32c and 32d are long holes extending in the lateral direction D1. Therefore, the position of the panel material 10 in the lateral direction D1 can be finely adjusted before the leg portion 12 located above is fixed to the base material 30A. Here, the panel material 10 is positioned by abutting the left end of the panel material 10 against (the locking piece 45 of) the circumferential edge 40C. Subsequently, panel members 10 are sequentially attached to the right side of the attached panel members 10 by the same procedure.

Note that the position of each panel material 10 in the horizontal direction D1 is finely adjusted so that the positions of the panel materials 10 adjacent to each other in the vertical direction D2 are aligned in the horizontal direction D1.

Subsequently, a step S6 for attaching the circumferential edge 40A is performed. In the mounting step S6 of the circumferential edge 40A, the bottom plate 44 is superimposed on the side plate 23 of the support member 20A, and the locking piece 45 is attached to the leg portion 12 of the uppermost panel material 10, as in the mounting step S4 of the circumferential edge 40. The circumferential edge 40A is arranged so as to be in contact with each other. The circumferential edge 40A is fixed to the side plate 23 of the support member 20A by a fixing member 64 near both ends in the longitudinal direction of the circumferential edge 40A.

Through the above steps, the decorative structure 1 is constructed on the outer wall 2.

In the decorative structure 1, the panel material 10, and the construction method of the decorative structure 1 described above, the insertion holes 12c and 12d provided in at least one of the four legs 12 of the panel material 10 are The panel material 10 is attached by inserting the projection 34 of one of the two base materials 30 adjacent to each other in the vertical direction D2. The four leg parts 12 are provided along the four sides of the outer edge part 11b, which has a square shape in plan view, and extend from the outer edge part 11b in a direction intersecting (orthogonal to) the main body part 11, and have the same shape. have. That is, the panel material 10 is rotationally symmetrical at 90 degrees, 180 degrees, 270 degrees, and 360 degrees about the central axis CX of the main body 11, except for the surface 11a. In other words, the four legs 12 of the panel material 10 are rotationally symmetrical at 90 degrees, 180 degrees, 270 degrees, and 360 degrees about the central axis CX of the main body 11. Therefore, the panel material 10 can be attached to the base material 30 by rotating it by any angle of 90 degrees, 180 degrees, 270 degrees, and 360 degrees about the central axis CX of the main body portion 11. As a result, it becomes possible to change the construction direction of the panel material 10.

The surface 11a of the panel material 10 has an asymmetrical decoration with respect to the central axis CX. Therefore, the decorative structure 1 can produce various expressions by arbitrarily attaching each panel material 10 at any rotation angle of 90 degrees, 180 degrees, 270 degrees, and 360 degrees. Can be done. Therefore, it becomes possible to improve the design of the decorative structure 1.

Each of the plurality of support members 20 includes a protrusion piece 25 that extends in the extending direction of the support member 20 and protrudes in the direction D3. Since each base material 30 is positioned by the protruding piece 25 of the support member 20, the installation work of the base material 30 can be simplified, and the construction accuracy of the base material 30 can be improved.

Specifically, the plurality of support members 20 include a support member 20A that supports a base material 30A, a support member 20B that supports a base material 30B, and support members 20C to 20E that support base materials 30C and 30D. The base material 30A is attached to the support member 20A with the protrusion 35 of the base material 30A in contact with the protrusion piece 25 of the support member 20A in the vertical direction D2. Since the position of the base material 30A in the vertical direction D2 is determined by this contact, the operator can omit the work of adjusting the position of the base material 30A in the vertical direction D2. Therefore, the work of attaching the base material 30A can be simplified.

The base material 30B is attached to the support member 20B with the protruding piece 25 of the support member 20B fitted into the groove 37 provided in the base material 30B. Since the position of the base material 30B in the vertical direction D2 is determined by this fitting structure, the operator can omit the work of adjusting the position of the base material 30B in the vertical direction D2. Therefore, the work of attaching the base material 30B can be simplified.

The base materials 30C, 30D are attached to the support members 20C, 20D, 20E with the base materials 30C, 30D fitted into the cutouts 25a provided in the protruding pieces 25 of the support members 20C, 20D, 20E. Since the positions of the base materials 30C and 30D in the vertical direction D2 are determined by this fitting structure, the operator can omit the work of adjusting the positions of the base materials 30C and 30D in the vertical direction D2. Therefore, the work of attaching the base materials 30C and 30D can be simplified.

In this way, the base material 30 can be systematically attached to the support member 20.

A stamp M is attached to the leg portion 12A of the panel material 10. Therefore, in the work instruction, the construction direction of the panel material 10 can be indicated by the direction of the marking M (up, down, left, and right). Therefore, since the operator can easily determine the construction direction of the panel material 10, it becomes possible to improve the workability of the panel material 10.

Support members 20A-20E are installed on the outer wall 2, and base materials 30A-30D are installed on the support members 20A-20E. Further, a plurality of panel materials 10 are attached to the base materials 30A to 30D. Therefore, it becomes possible to construct the panel material 10 without being affected by the shape of the outer wall 2.

The support members 20C to 20E are arranged in the vertical direction D2 orthogonal to the extending direction (horizontal direction D1) of the siding panel 5, and are attached to span two siding panels 5 that are adjacent to each other in the vertical direction D2. With this configuration, the female end 52 of the upper siding panel 5 and the male end 51 of the lower siding panel 5 are difficult to disengage. As a result, it becomes possible to improve the wind pressure resistance performance of the outer wall 2.

The left end panel material 10 is positioned by abutting the left end of the panel material 10 against (the locking piece 45 of) the circumferential edge 40C. The panel members 10 other than the left end are positioned by abutting the left end of the panel member 10 against the right end of the panel member 10 located on the left side of the panel member 10. With this configuration, it is possible to reduce the gap (joint) between two panel members 10 adjacent to each other in the lateral direction D1.
