Description

[Technical Field]

[0001] The present invention relates to a roof structure having a ceiling surface formed by arranging a plurality of elongated members. [Background technology]

[0002] Conventionally, roof structures have been known in which the upper ends of a pair of posts erected on the ground are connected to the lower parts of beams that extend in a direction intersecting the posts, and for example, in Patent Document 1, the roof structure is constructed by multiple long members (long components) that are lined up in a row in the direction in which the beams extend and are fitted and connected to each other. The bottom surface of each long member is formed flat (planar), and the ceiling surface of the roof structure formed by the multiple long members is planar.

[0003] In recent years, there has been a demand for higher design capabilities in roof structures such as carports. For example, narrowing the width of long members and applying a wood-grain finish to create a wood-panel look with many narrow wooden boards lined up can create a delicate and elaborate impression, resulting in higher design capabilities.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-123647 Summary of the Invention [Problem to be solved by the invention]

[0005] When a roof body is formed using narrow, elongated members, the number of elongated members that make up a roof body of the same size increases, resulting in a large number of parts and an increase in the amount of work required for construction, making construction more complicated and increasing costs.

[0006] The present invention has been made in consideration of the above-mentioned problems of the prior art, and its object is to provide a roof body that is inexpensive and has excellent workability and design. [Means for solving the problem]

[0007] The main invention for achieving this objective is a roof body having a ceiling surface formed by arranging a plurality of elongated members, wherein the elongated members have a plurality of decorative areas along the longitudinal direction of the elongated members, spaced approximately equally apart from each other in the short direction of the elongated members, and the spacing between the decorative areas is narrower than the width of the decorative areas in the short direction. Other features of the present invention will become apparent from the description of this specification and the accompanying drawings. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a roof body that is inexpensive, easy to install, and has excellent design. [Brief explanation of the drawings]

[0010] An embodiment of the fitting of the present invention will be described with reference to the drawings. In this embodiment, as an example of a roof structure having a roof body according to the present invention, a carport 1 having a rectangular outer shape and intended to accommodate a flat parking space, as shown in Figures 1 to 3, will be described.

[0011] The carport 1 of this embodiment comprises two pillars 10, two beams 20 attached to each pillar 10, two main structures 30 attached across the two beams 20, and a roof body 40 attached to the main structures 30.

[0012] In the following explanation, the up-down direction in the rectangular parking space in which the carport 1 is installed is referred to as the up-down direction, the long side of the parking space is referred to as the depth direction, and the short side of the parking space is referred to as the left-right direction. Also, as shown in Figures 1 to 3, the pillar side in the left-right direction is referred to as the left side, and the opposite side is referred to as the right side, and one side in the depth direction (the left side in Figure 2) is referred to as the front side, and the other side (the right side in Figure 2) is referred to as the back side.

[0013] The pillars 10 are formed from extruded material such as aluminum alloy and have a rectangular cross section. The two pillars 10 are installed vertically along the left edge of the parking space, spaced apart in the longitudinal direction, and are the same height. As shown in Figure 4, the pillars 10 are provided with a pillar cover 11 on the side surface 10A facing the parking space, with a gap between them.

[0014] The beams 20 are formed from extruded shapes such as aluminum alloy, and are arranged in the left-right direction. Each beam 20 is fixed to the upper end of the column 10 with an inclination such that the end on the column 10 side is lower. As shown in Fig. 5, the beam 20 is integrally formed with a beam main body 20A having a rectangular cross section and a purlin support piece 20B that protrudes along the underside of the beam main body 20A on both sides in the depth direction from the lower edge of the beam main body 20A.

[0015] The purlins 30 are formed from extruded shapes such as aluminum alloy, and are arranged along the depth direction and fixed to the underside of the beams 20 as shown in FIG. 3. As shown in FIG. 6, the purlins 30 are integrally formed with a purlin main body 30A having a rectangular cross section and roof support pieces 30B that protrude from the lower edge of the purlin main body 30A on both sides in the left-right direction along the underside of the purlin main body 30A. As shown in FIG. 3, the length of the purlins 30 is set longer than the distance between the two beams 20 in the depth direction. In this embodiment, the two purlins 30 are arranged parallel to each other with a distance between them in the left-right direction in the depth direction, which is perpendicular to the longitudinal direction of the beams 20.

[0016] As shown in Figure 3, the roof body 40 has a roof portion 41, side frames 42, gutter frames 43, a right frame 44, and a left frame 45. The roof portion 41 has a rectangular outer shape formed by arranging and connecting multiple roof materials 46, 47, and 48 that are arranged above the parking space and form the ceiling surface. The multiple roof materials 46, 47, and 48 are all extruded aluminum members, and are arranged with their longitudinal directions (extrusion directions) facing left and right, and lined up in the depth direction. Here, the roof materials 46, 47, and 48 correspond to the elongated members that are lined up to form the ceiling surface.

[0017] 3 and 5, the multiple roofing materials 46, 47, 48 in the roof portion 41 include two first roofing materials 46 arranged at both ends in the depth direction, a second roofing material 47 connected to one of the two first roofing materials 46, and multiple third roofing materials 48 arranged between the other of the two first roofing materials 46 and the second roofing material 47. In other words, the majority of the roof portion 41 is formed by connecting multiple third roofing materials 48, and the first roofing material 46 is connected to the back end of the area where the multiple third roofing materials 48 are connected, and the first roofing material 46 is connected to the front end via the second roofing material 47.

[0018] As shown in Fig. 7, the third roofing member 48 has a base portion 48A, a hanging side wall portion 48B, a first overlapping piece portion 48C, an engagement receiving portion 48D, an engagement wall portion 48E, a receiving side wall portion 48F, and a second overlapping piece portion 48G. The base portion 48A extends horizontally and is generally flat. The base portion 48A has two grooves 48H recessed upward along the left-right direction, and the grooves 48H are provided so as to divide the width of the base portion 48A in the short side direction (depth direction) into thirds. Note that the grooves 46H, 47H, and 48H provided in the roofing members 46, 47, and 48 are omitted from Figs. 2 and 3.

[0019] The two grooves 48H are substantially perpendicular to the underside of the base portion 48A and have a pair of groove side walls 48I that face each other with a gap in the short direction of the third roof material 48, and a groove bottom 48J that connects the upper ends of the pair of groove side walls 48I. A laminate sheet 49 decorated with, for example, a wood grain pattern is attached to the flat portion 48K that forms the underside of the base portion 48A. In Figure 7, the decorated area where the laminate sheet 49 is attached is indicated by a dashed line.

[0020] Each flat surface portion 48K to which the laminate sheet 49 is attached has a width W1 in the short side direction that is approximately equal, and the interval W2 between adjacent flat surfaces 48K is narrower than the width W1 of each flat surface portion 48K. In addition, in the short side direction of the third roof material 48, both ends of the flat surface portion 48K of the base surface portion 48A, including the corners connecting to the pair of groove side walls 48I, have a small radius ( For example, the groove 48H is formed to have a curved surface (for example, about 0.3 mm). Therefore, the interval W2 between the adjacent flat portions 48K and the width of the groove 48H are substantially the same.

[0021] The base portion 48A has flat portions 48K (decorative areas) spaced at approximately equal intervals from each other in the short direction, making the third roofing material 48 appear as if it were three wooden boards arranged side by side. The shape of the third roofing material 48 has a color with a lighter lightness than the wood grain pattern on the laminate sheet 49, so that the groove portions 48H exposed between the laminate sheet 49 appear as shadows of the wooden boards. The flat portions 48K forming the underside of the base portion 48A to which the laminate sheet 49 is attached correspond to the decorative areas. The configuration in which the pair of groove side walls 48I forming the groove portions 48H are approximately perpendicular to the undersides of the flat portions 48K forming the decorative areas, and the configuration in which the intervals between adjacent flat portions 48K are approximately equal, also includes cases in which a ceiling formed by arranging wooden boards has a tilt or the like that corresponds to an error that may occur due to the manufacturing and processing of the wooden boards, the construction of the ceiling, etc.

[0022] The hanging side wall portion 48B extends substantially vertically from one edge of the base surface portion 48A. The first overlapping piece portion 48C extends substantially horizontally from the upper edge of the hanging side wall portion 48B to the side opposite the base surface portion 48A. A hanging piece 48L is provided at the tip of the first overlapping piece portion 48C and hangs downward.

[0023] The engagement receiving portion 48D protrudes from a position approximately in the middle of the hanging side wall portion 48B on the surface of the hanging side wall portion 48B opposite the base surface portion 48A, with the protruding tip extending downward to form a groove-shaped recessed portion 48M recessed upward between the hanging side wall portion 48B and the engagement wall portion 48E. The engagement wall portion 48E has a first wall portion 48N extending approximately vertically upward from the other edge of the base surface portion 48A, a recessed bottom portion 48O extending approximately horizontally from the upper end of the first wall portion 48N toward the opposite side from the base surface portion 48A, and a second wall portion 48P extending approximately vertically upward from the tip of the recessed bottom portion 48O.

[0024] The receiving side wall portion 48F is provided at the other end of the base surface portion 48A with a gap between it and the engaging wall portion 48E toward the hanging side wall portion 48B, and extends substantially vertically from the upper surface of the base surface portion 48A. The second overlapping piece portion 48G extends substantially horizontally from the upper edge of the receiving side wall portion 48F to the side opposite the hanging side wall portion 48B.

[0025] The dimension from the underside of the base portion 48A to the underside of the first overlapping piece portion 48C is approximately equal to the dimension from the underside of the base portion 48A to the upper surface of the second overlapping piece portion 48G, and the distance between the hanging side wall portion 48B and the hanging piece 48L is wider than the width of the second overlapping piece portion 48G.

[0026] 8, the first roofing material 46 has a base surface 46A having two groove portions 46H formed by a pair of groove side walls 46I and a groove bottom portion 46J, and a flat portion 46K, similar to the base surface 48A of the third roofing material 48. As with the third roofing material 48, a laminate sheet 49 is attached to the flat portion 46K of the first roofing material 46.

[0027] One depth-wise edge of the base surface portion 46A is provided with a hanging side wall portion 46B similar to the hanging side wall portion 48B of the third roofing material 48, a first overlapping piece portion 46C similar to the first overlapping piece portion 48C, and an engagement receiver 46D similar to the engagement receiver 48D. The other depth-wise edge of the base surface portion 46A is provided with a frame position restricting portion 46Q that rises substantially vertically, a side frame support wall portion 46R that is spaced apart from the frame position restricting portion 46Q and closer to the hanging side wall 46B, extending substantially vertically from the top surface of the base surface portion 46A, and a frame receiving wall portion 46S that extends substantially horizontally from the upper edge of the side frame support wall 46R toward the hanging side wall 46B. Two protrusions 46T are spaced apart in the depth direction on the top surface of the frame receiving wall portion 46S, protruding upward at the same height along the length of the first roofing material 46.

[0028] 9, the second roofing material 47 has a base surface 47A having two groove portions 47H formed by a pair of groove side walls 47I and a groove bottom portion 47J, and a flat portion 47K, similar to the base surface 48A of the third roofing material 48. A laminate sheet 49 is also attached to the flat portion 47K of the second roofing material 47, similar to the third roofing material 48.

[0029] The second roofing material 47 has, on both sides in the depth direction of the base surface portion 47A, an engaging wall portion 47E similar to the engaging wall portion 48E, a receiving side wall portion 47F similar to the receiving side wall portion 48F, and a second overlapping piece portion 47G similar to the second overlapping piece portion 48G. Here, the flat portions 46K, 47K forming the lower surfaces of the base surface portions 46A, 47A to which the laminate sheet 49 is attached also correspond to decorative areas.

[0030] As shown in Figures 3 and 5, the roof portion 41 has a first roof material 46 arranged at both ends in the depth direction, a second roof material 47 arranged next to the first roof material 46 on the front side, and multiple third roof materials 48 arranged between the second roof material 47 and the first roof material 46 on the back side, and each is connected to the other.

[0031] The multiple third roofing members 48 arranged side by side are each positioned so that the hanging side wall portion 48B is located on the front side and the receiving side wall portion 48F is located on the back side. As shown in Figures 5 and 10, two adjacent third roofing members 48 in the depth direction are arranged side by side with the second wall portion 48P of the front third roofing member 48 inserted into the recessed portion 48M of the back third roofing member 48. In this case, the upper surface of the second overlapping piece portion 48G of the front third roofing member 48 abuts the lower surface of the first overlapping piece portion 48C of the back third roofing member 48, so that the lower surfaces of the flat portions 48K of the two adjacent third roofing members 48 are approximately flush. Adjacent third roofing members 48 are connected to each other by screws 5 that penetrate the roof support piece portion 30B and the first overlapping piece portion 48C of the purlin 30 and are screwed into the second overlapping piece portion 48G.

[0032] Between the two arranged third roofing members 48, a connecting recess 41A is formed along the longitudinal direction of the third roofing members 48, recessed upward between the first wall portion 48N of the front third roofing member 48 and the hanging side wall portion 48B of the rear third roofing member 48. The width W3 of the connecting recess 41A is approximately the same as the width W2 of the groove 48H, and the connecting recess 41A and the groove 48H are configured to have approximately the same depth. The configuration in which the width W3 of the connecting recess 41A and the width W2 of the groove 48H are approximately equal also includes cases in which a ceiling formed by arranging wooden boards has a tilt or other error that may occur due to the manufacturing and processing of the wooden boards or the construction of the ceiling. Here, the first wall portion 48N and the hanging side wall portion 48B correspond to side walls that connect adjacent decorative areas of the connecting recess 41A, and the recessed bottom portion 48O corresponds to a bottom that connects to the end of the side wall.

[0033] As shown in Figures 5 and 11, the third roofing material 48 arranged at the farthest side is arranged next to the first roofing material 46, with the second wall portion 48P of the third roofing material 48 inserted into the recessed portion 46M of the adjacent (farther) first roofing material 46. At this time, the upper surface of the second overlapping piece portion 48G of the third roofing material 48 abuts against the lower surface of the first overlapping piece portion 46C of the first roofing material 46, so that the lower surface of the flat portion 48K of the third roofing material 48 and the flat portion 46K of the first roofing material 46 are approximately flush with each other. The adjacent first roofing material 46 and third roofing material 48 are connected by screws 5 that penetrate the roof support piece portion 30B and the first overlapping piece portion 46C of the purlin 30 and are screwed into the second overlapping piece portion 48G.

[0034] Between the first roof material 46 and the third roof material 48, a connecting recess 41A recessed upward is formed along the longitudinal direction of the first roof material 46 and the third roof material 48, between the first wall portion 48N of the third roof material 48 and the hanging side wall portion 46B of the first roof material 46, similar to the area between the two third roof materials 48.

[0035] As shown in Figures 5 and 12, the third roofing material 48 arranged closest to the first roofing material 47 is arranged next to the second roofing material 47, with the second wall portion 47P of the adjacent second roofing material 47 inserted into the recessed portion 48M of the third roofing material 48. At this time, the upper surface of the second overlapping piece portion 47G of the second roofing material 47 abuts against the lower surface of the first overlapping piece portion 48C of the third roofing material 48, so that the lower surface of the flat portion 47K of the second roofing material 47 and the flat portion 48K of the third roofing material 48 are approximately flush with each other. The adjacent second roofing material 47 and third roofing material 48 are connected by screws 5 that penetrate the roof support piece portion 30B and the first overlapping piece portion 48C of the purlin 30 and are screwed into the second overlapping piece portion 47G.

[0036] Between the second roof material 47 and the third roof material 48 arranged in the depth direction, a connecting recess 41A recessed upward is formed along the longitudinal direction of the second roof material 47 and the third roof material 48, between the first wall portion 47N of the second roof material 47 and the hanging side wall portion 48B of the third roof material 48, similar to the area between the two third roof materials 48.

[0037] The first roofing material 46 is arranged next to the second roofing material 47 on the side opposite the third roofing material 48. As shown in FIGS. 5 and 13, the adjacent first roofing material 46 and second roofing material 47 are arranged side by side with the second wall portion 47P of the second roofing material 47 inserted into the recessed portion 46M of the first roofing material 46. At this time, the upper surface of the second overlapping piece portion 47G of the second roofing material 47 abuts against the lower surface of the first overlapping piece portion 46C of the first roofing material 46, so that the lower surface of the flat portion 46K of the first roofing material 46 and the flat portion 47K of the second roofing material 47 are approximately flush with each other. The adjacent first roofing material 46 and second roofing material 47 are connected by a screw 5 that penetrates the roof support piece portion 30B and the first overlapping piece portion 46C of the purlin 30 and is screwed into the second overlapping piece portion 47G.

[0038] Between the first roof material 46 and the second roof material 47 that are arranged side by side, a connecting recess 41A that is recessed upward is formed along the longitudinal direction of the first roof material 46 and the second roof material 47, between the first wall portion 47N of the second roof material 47 and the hanging side wall portion 46B of the first roof material 46, similar to between the two third roof materials 48.

[0039] The underside of the flat portion 46K of the first roof material 46, the underside of the flat portion 47K of the second roof material 47, and the underside of the flat portion 48K of the third roof material 48 arranged side by side in this manner form a substantially flush ceiling surface. In addition, connecting recesses 41A similar to the grooves 46H, 47H, 48H of the roof materials 46, 47, 48 are formed between the roof materials 46, 47, 48.

[0040] That is, roof section 41, which is made up of roofing materials 46, 47, and 48 arranged side by side, has a plurality of flat sections 46K, 47K, and 48K arranged in the depth direction, which form the undersides of base sections 46A, 47A, and 48A, which are divided at approximately equal intervals by grooves 46H, 47H, and 48H and connecting recesses 41 A. Laminate sheets 49 with a wood grain pattern are attached to each of flat sections 46K, 47K, and 48K, and grooves 46H, 47H, and 48H and connecting recesses 41 A exposed between each laminate sheet 49 have a color that is lighter in color than the wood grain pattern applied to laminate sheet 49.

[0041] Therefore, when the roof portion 41 is viewed from below, the flat portions 46K, 47K, 48K to which the laminate sheet 49 is attached appear to be a plurality of wooden boards arranged at equal intervals with slight gaps between them, and the groove portions 46H, 47H, 48H and the connecting recess 41A appear to be gaps or shadows between the arranged wooden boards, giving the appearance of real wooden boards arranged with thickness.

[0042] The first roofing material 46, second roofing material 47, and third roofing material 48 that make up the roof portion 41 are supported on the underside of the main house 30 via roof support piece portion 30B of the main house 30. The ends of the first roofing material 46, second roofing material 47, and third roofing material 48 that make up the roof portion 41 on the side of the pillar 10 are arranged with a gap between them and the pillar 10, as shown in FIG. 4, and are arranged so as to be located above a gutter frame 43 that is fixed to the pillar 10 via a bracket 12, and each roofing material 46, 47, and 48 is fixed to the gutter frame 43 so that rainwater on the roof portion 41 flows into the gutter frame 43. End caps 51 are attached to both ends of the gutter frame 43, which form the small ends, as shown in FIG. 5.

[0043] The side frames 42 are formed from the same extruded material as the right frame 44 and left frame 45. As shown in FIG. 5, the side frames 42 are attached so as to cover from the sides the side frame support wall portions 46R of the first roof material 46 located on both sides of the roof portion 41. The side frames 42 have side frame fixing portions 42B extending from the upper part of the cover portion 42A facing the side frame support wall portions 46R at a distance, which are positioned above the frame receiving wall portions 46S and attached from above with screws 6. The right frame 44 and left frame 45 differ in shape from the side frame 42 in that the portions of the side frame 42 corresponding to the cover portions 42A protrude upward from the side frame 42.

[0044] 14, the right frame 44 is attached so as to cover the end of the roof portion 41 opposite the pillar 10. The right frame 44 is attached to the right edge of the roof portion 41 by overlapping the side frame fixing portions 44B extending from the top of the cover portions 44A facing the edges of the roof materials 46, 47, 48 that make up the roof portion 41 with the side frame fixing portions 44B on each of the roof materials 46, 47, 48 and then screwing them in from above.

[0045] As shown in FIG. 15 , the left frame 45 is attached to the gutter frame 43, which is fixed to the column 10 side of the roof portion 41, so as to cover the gutter frame 43 from the column 10 side. The left frame 45 is attached to the gutter frame 43 by screwing a side frame fixing portion 45B extending from the top of the cover portion 45A facing the column 10 side portion of the gutter frame 43 to a fixing portion 43A located at the top of the column 10 side of the gutter frame 43. The left frame 45 is provided only on the gutter frame 43 excluding the portion facing the column 10. The right frame 44, left frame 45, and side frames 42 are attached to surround the outer periphery of the roof portion 41 to which the gutter frame 43 is attached, and resin corner caps 50 are attached between the right frame 44 and the left frame 45 and the side frame 42 to connect them to each other, as shown in FIG. 3 .

[0046] According to the roof body 40 of this embodiment, the first roof material 46, second roof material 47, and third roof material 48 that constitute the roof portion 41 are made up of flat portions 46K, 47K, and 48K to which laminate sheets 49 are attached, and have multiple decorative areas along the longitudinal direction, and the multiple flat portions 46K, 47K, and 48K are arranged at approximately equal intervals from each other in the short direction of each roof material 46, 47, and 48, so that it is easy to visually recognize that multiple long components separated by flat portions 46K, 47K, and 48K are actually arranged.

[0047] Furthermore, because the spacing between the planar portions 46K, 47K, and 48K is narrower than the width of the planar portions 46K, 47K, and 48K in the short direction, the planar portions 46K, 47K, and 48K to which the laminate sheet 49 is attached are easily recognized as different long members, and the gaps between adjacent planar portions 46K, 47K, and 48K are easily recognized as gaps between adjacent long members. For this reason, the roofing material gives a more delicate and elaborate impression than roofing materials made of members with wide planar portions, and is therefore superior in design.

[0048] Furthermore, simply attaching one of the first roofing material 46, second roofing material 47, and third roofing material 48 makes it appear as if multiple narrow, long members are attached, which reduces the number of construction steps and costs compared to attaching narrow, long members side by side. This makes it possible to provide a roof body 40 that is inexpensive, easy to install, and has excellent design.

[0049] Furthermore, because the first roofing material 46, the second roofing material 47, and the third roofing material 48 are formed from materials with a lower brightness than the laminate sheet 49, it is possible to emphasize the flat portions 46K, 47K, and 48K (decorative areas) to which the laminate sheet 49 is attached, more than the material of the roofing materials 46, 47, and 48 that is exposed between the adjacent flat portions 46K, 47K, and 48K. It is also possible to make the roofing materials 46, 47, and 48 that are exposed between the adjacent flat portions 46K, 47K, and 48K appear as if they are the shadows of multiple long members made up of the flat portions 46K, 47K, and 48K to which the laminate sheet 49 is attached. This further enhances the design.

[0050] In addition, in this embodiment, the decoration of the laminate sheet 49 attached to each flat surface portion 46K, 47K, 48K (decorative area) is made to have a wood grain pattern, so that each flat surface portion 46K, 47K, 48K (decorative area) can be visually perceived as being formed from different wooden boards.

[0051] In addition, because the widths of the planar portions 46K, 47K, and 48K that make up the decorative area are all the same, it is possible to create the illusion of narrow wooden boards being lined up in real life. Also, it is possible to achieve a design in which long wooden boards that are narrower than the actual widths of the roofing materials 46, 47, and 48 are lined up evenly, using fewer roofing materials 46, 47, and 48.

[0052] Furthermore, as in this embodiment, forming a decorative area by attaching a decorated laminate sheet 49 to the flat portions 46K, 47K, and 48K makes it possible to easily form a decorative surface, and by attaching laminate sheets with different patterns, it is possible to form a ceiling surface with a variety of decorative designs. In this embodiment, the decorative design is a wood grain pattern, but this is not limited to this. Also, while an example has been described in which a decorated laminate sheet is attached to the decorative area, this is not limiting, and the decorative design may also be achieved by attaching a wrapping sheet, painting, printing, or the like.

[0053] In addition, between each flat portion 46K, 47K, 48K (decorative area) of each roof material 46, 47, 48 to which laminate sheet 49 is attached are groove portions 46H, 47H, 48H that are recessed upward along the longitudinal direction, and therefore the groove portions 46H, 47H, 48H cast shadows, making it possible to visually see that the separate components for each flat portion 46K, 47K, 48K are spaced apart.

[0054] Furthermore, the width of the connecting recess 41A formed at the connecting portion where two adjacent roof materials 46, 47, 48 are connected to each other is approximately equal to the width of the grooves 46H, 47H, 48H of each roof material 46, 47, 48, so it is difficult to distinguish between the connecting recess 41A and the grooves 46H, 47H, 48H. As a result, the boundary between two adjacent roof materials 46, 47, 48 is difficult to see, making it possible to make it appear as if long members narrower than the width of the roof materials 46, 47, 48 are lined up at equal intervals along the entire length in the depth direction of the roof portion 41.

[0055] Furthermore, the groove side walls 46I, 47I, 48I of the grooves 46H, 47H, 48H, and the first wall portions 47N, 48N and hanging side walls 46B, 48B that form the connecting recess 41A are generally perpendicular to the flat surfaces 46K, 47K, 48K of the roofing materials 46, 47, 48, so the grooves 46H, 47H, 48H and the connecting recess 41A, which are recessed upward, are likely to be shaded. This makes it possible to more clearly emphasize the appearance of adjacent flat surfaces 46K, 47K, 48K as if they are separated by the grooves 46H, 47H, 48H and the connecting recess 41A.

[0056] In the above-described embodiment, pillars 10 are provided only on one side edge of the parking space. However, pillars may be provided on the other side edge, with cross members spanning between the pillars. In this case, the number of pillars and beams supporting the roof structure and the number of roofing materials constituting the roof structure can be appropriately determined depending on the size of the roof structure. Furthermore, the direction along which the longitudinal direction of the roofing materials is aligned can be set according to the shape of the parking space, and the slope of the roof structure is set so that the height changes along the longitudinal direction of the roofing materials. In the above-described embodiment, the beams 20 are arranged at an angle, but the beams do not necessarily have to be angled.

[0057] The above-described embodiments are provided to facilitate understanding of the present invention and are not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and the present invention includes equivalents thereof.

[0058] This embodiment discloses a roof structure as described in the following items (1) to (8). (1) A roof body having a ceiling surface formed by arranging a plurality of elongated members, wherein the elongated members have a plurality of decorative areas along the longitudinal direction of the elongated members, the decorative areas being spaced apart approximately equally in the lateral direction of the elongated members, and the spacing between the decorative areas is narrower than the width of the decorative areas in the lateral direction.

[0059] In the roof structure described in (1), the elongated member has multiple decorative areas along its length, and the multiple decorative areas are spaced at approximately equal intervals from each other in the short-side direction of the elongated member, making it easy to visually recognize that multiple members, each separated by a decorative area, are arranged side by side. Furthermore, because the spacing between the decorative areas is narrower than the width of the decorative areas in the short-side direction, the spaces between the decorative areas, which are recognized as different elongated members, are easily recognized as gaps between adjacent elongated members. This provides a superior design compared to roofing materials formed from a single member with a wide flat surface.

[0060] Furthermore, simply attaching one long member makes it appear as if multiple narrow, long members are attached, which reduces the number of construction steps and costs compared to attaching a series of narrow, long members side by side. This makes it possible to provide a roof structure that is inexpensive, easy to install, and has excellent design.

[0061] (2) In the roof structure described in (1), the elongated members are formed of materials having a lower brightness than the decorative area.

[0062] In the roof structure described in (2), the elongated members are made of materials with a lower brightness than the decorative areas, so it is possible to emphasize each decorative area more than the material of the elongated members exposed between adjacent decorative areas. Also, it is possible to make the elongated members exposed between adjacent decorative areas visible as if they were the shadows of multiple roofing materials made up of decorative areas. This allows for a more aesthetically pleasing design.

[0063] (3) In the roof structure described in (1) or (2), the decorative area is characterized in that the decorative area has a wood grain pattern.

[0064] In the roof structure described in (3), the decorative areas have a wood grain pattern, so that each decorative area can be visually perceived as being made of different wooden boards.

[0065] (4) In the roof body described in any one of (1) to (3), the elongated member is characterized in that it has a groove portion recessed upward along the longitudinal direction between the decorative areas.

[0066] In the roof structure described in (4), the spaces between the decorative areas of the long members are grooved upward along the longitudinal direction, so the grooves cast shadows, making it possible to visually recognize that real long members are separated into decorative areas and spaced apart.

[0067] (5) In the roof body described in (4), a connecting recess that is recessed upward is formed at the connecting portion where two adjacent elongated members are connected to each other, and the width of the connecting recess is approximately equal to the width of the groove portion.

[0068] In the roof structure described in (5), the width of the connecting recess formed at the connecting portion where two adjacent elongated members are connected to each other is approximately equal to the width of the groove portion of each elongated member, making it difficult to distinguish between the connecting recess and the groove portion. As a result, the boundary between two adjacent elongated members is difficult to see, making it possible to make it appear as if elongated members narrower than the width of the elongated members are lined up at equal intervals across the entire width of the roof structure.

[0069] (6) In the roof body described in (4), the connecting portion where two adjacent elongated members are connected to each other has a connecting recess recessed upward, and the groove portion and the connecting recess have side walls each connected to the adjacent decorative areas and a bottom connected to the end of the side wall, and the side walls are approximately perpendicular to the surface forming the decorative area of ​​the elongated member.

[0070] In the roof body described in (6), the side walls of the groove portions and connecting recesses are approximately perpendicular to the surface forming the decorative area of ​​the elongated member, so that the groove portions and connecting recesses recessed upward cast a shadow, making it possible to more clearly emphasize the appearance of adjacent decorative areas as if they were separated by the groove portions and connecting recesses.

[0071] (7) The roof structure according to any one of (1) to (6) is characterized in that a sheet material with a decorative finish is attached to the decorative area.

[0072] In the roof body described in (7), the decorative area is covered with a decorative sheet material, so by attaching sheet materials with different patterns, it is possible to form a ceiling surface with various decorative finishes.

[0073] (8) The roof structure according to any one of (1) to (8) is characterized in that the widths of the decorative areas are approximately equal.

[0074] In the roof body described in (8), the width of each decorative area is approximately equal, so it is possible to achieve a design in which long components narrower than the actual width of the long components are evenly arranged, using fewer long components. [Explanation of symbols]
