Summary of the Invention

Problems to be Solved by the Invention

[0004] The carport described in Patent Document 1 is composed of a double support structure, and two pairs of columns support the roof body at four locations on both sides in the left-right direction of the carport. In the carport (roof structure), when the columns are installed on the front side, when a lighting unit is provided in the roof body main body and wiring for supplying power to the lighting unit is routed, the wiring of the lighting unit may be visible from below the roof body main body, which may impair the design. Therefore, there is room for improvement regarding the routing of the wiring of the lighting unit.

[0005] An object of the present disclosure is to provide a roof structure that can improve the design regarding the routing of the wiring of the lighting unit.

[Modes for carrying out the invention]

[0008] The first embodiment of the roof structure of this disclosure will be described below with reference to Figures 1 to 5. In this embodiment, an example in which the roof structure is applied to a carport 1 will be described. However, this embodiment is not limited to an example in which the roof structure is applied to a carport 1. For example, the roof structure may be applied to structures other than carports, such as bicycle parking areas, shelters, rest areas, terraces, bus stops, etc.

[0009] In the description of the first embodiment shown in Figures 1 and 2, the direction in which the multiple roofing materials 411 (long pieces) constituting the roof body 41 of the carport 1 in the first embodiment extend is also referred to as the front-rear direction Y (longitudinal direction of the roofing material 411). In this embodiment, the roof body 4 is inclined in the front-rear direction Y, and in the front-rear direction Y, the upstream side on the right rear side in Figure 1 is also referred to as the front side Y2, and the downstream side on the left front side in Figure 1 is also referred to as the rear side Y1. In addition, the direction in which the multiple roofing materials 411 (long pieces) constituting the roof body 41 of the roof body 4 are lined up is also referred to as the left-right direction X. In the left-right direction X, one side is referred to as the X1 side, and the other side is referred to as the X2 side.

[0010] The overall structure of the carport 1 of the first embodiment will now be described. As shown in Figures 1 and 2, the carport 1 of this embodiment is a so-called double-support structure carport in which the roof body 4 is supported by two pairs of columns 2 on each side in the left-right direction X. Furthermore, the carport 1 of this embodiment is configured as a suspension structure in which the roof body 4 is suspended and connected to the lower part (below) of the beams 3 connected to the columns 2. As shown in Figures 1 and 2, three lighting units 43 are attached to the underside of the roof body 41. Wiring cables W are connected to the three lighting units 43. Power is supplied to the three lighting units 43 via the wiring cables W. The wiring structure of the lighting units 43 will be described after the overall structure of the carport 1 has been described.

[0011] As shown in Figures 1 and 2, the carport 1 of this embodiment comprises two pairs of columns 2 erected on the ground, two beams 3 extending from the upper ends of the columns 2 in a direction intersecting the columns 2, a roof body 4 positioned below the two beams 3, and three lighting units 43. The columns 2 and beams 3 are formed from extruded aluminum profiles and have a hollow structure with a hollow cross-section. The roof body 4 is indirectly connected to the two pairs of columns 2 via the two beams 3. The roof body 4 is directly connected to the two beams 3. Alternatively, the roof body 4 may be indirectly connected to the beams 3 via indirect members.

[0012] Two pairs of columns 2 are arranged side by side in the front-to-back direction Y. The pairs of columns 2 are arranged opposite each other on both sides of the carport 1 in the left-to-right direction X, with the roof body 4 in between, and are connected to both ends of the beam 3 in the left-to-right direction X. The two pairs of columns 2 are arranged spaced apart in the front-to-back direction Y of the carport 1. The columns 2 are formed by extending in the vertical direction.

[0013] The two sets of columns 2 include: Column 21 located at the rear Y1 end in the front-to-back direction Y and on the X2 end in the left-to-right direction X; Column 22 located at the rear Y1 end in the front-to-back direction Y and on the X1 end in the left-to-right direction X; Column 23 (one-side column) located at the front Y2 end in the front-to-back direction Y and on the X2 end in the left-to-right direction X; and Column 24 located at the front Y2 end in the front-to-back direction Y and on the X1 end in the left-to-right direction X. Unless otherwise specified, columns 21, 22, 23, and 24 are simply referred to as "Column 2".

[0014] As shown in Figure 1, the two beams 3 are spaced apart in the front-to-back direction Y of the carport 1. Each of the two beams 3 extends in the left-to-right direction X of the roof body 4. The left-to-right ends of the two beams 3 (the end on the X1 side and the end on the X2 side) are connected to the upper ends of the columns 2. The roof body 4 is connected to the lower parts of the two beams 3. The two beams 3 are positioned on the upper surface of the roof body 4 and are fixed to the upper surface of the roof body 4.

[0015] At the lower part of each of the two beams 3, as shown in FIG. 1, an extension plate 31 extending toward the central side in the front-rear direction Y of the roof body 4 (the side of the beam 3 different from the said beam 3 among the two beams 3) is formed.

[0016] The extension plate 31 is formed in a plate shape extending in the left-right direction X. The extension plate 31 is connected to each of a plurality of roof members 411 of the roof body main body 41 disposed below the beam 3. Note that the connection between the beam 3 and the roof body 4 is not limited to the configuration using the extension plate 31 of the beam 3. For example, a configuration in which the roof body 4 is directly bolted to the bottom surface of the beam 3 or a configuration in which the beam 3 and the roof body 4 are connected via another L-shaped metal fitting or the like may be used.

[0017] As shown in FIG. 1, the roof body 4 has a hanging structure in which the roof body is suspended below the lower part of the two beams 3. The roof body 4 is connected to the extension plates 31 formed at the lower part of each of the two beams 3. The roof body 4 has an upper surface formed with concavities and convexities and a lower surface formed flat (planar). The roof body 4 is formed with a downward slope that descends toward the rear side Y1 in the front-rear direction Y.

[0018] As shown in FIGS. 1 and 2, the roof body 4 has a roof body main body 41 and two guide gutters 42. The roof body main body 41 has a plurality of roof members 411 (long members), a rear frame 412, a front frame 413 (one-side end frame), and a pair of side frames 414.

[0019] As shown in FIGS. 1 and 2, the plurality of roof members 411 are arranged side by side in the left-right direction X in which the beam 3 extends and are fitted and connected (joined) to each other. The plurality of roof members 411 each extend parallel to the front-rear direction Y of the carport 1 and have a predetermined thickness. The roof body main body 41 is configured by arranging and connecting a plurality of roof members 411 extending in parallel. All of the plurality of roof members 411 are formed of extruded profiles of aluminum material.

[0020] Multiple roofing materials 411 are formed, for example, with an uneven upper surface and a flat (planar) lower surface. As a result, the roof body 41 is made up of multiple roofing materials 411 connected together, and as a whole, the lower surface is formed to be flat (planar) and the upper surface has an uneven surface.

[0021] The multiple roofing materials 411 that make up the roof body 41 may be configured as hollow structures with hollow sections, or as solid structures with no upper surface of the hollow section and an open upper side. Furthermore, the upper surface of the roof body 41 may be formed flat (planar).

[0022] The roof body 41 is formed with a downward slope in the front-rear direction Y, from the front side Y2 to the rear side Y1, as the roofing material 411 extends in the front-rear direction Y. Thus, the roof body 41 is formed with a front-rear gradient that slopes downward from the front side Y2 to the rear side Y1 in the front-rear direction Y. In this embodiment, for example, the inclination angle of the roof body 41 in the front-rear direction Y is set to approximately 1° to 6°. Furthermore, the roof body 41 is not inclined in the left-right direction X, and extends horizontally, for example. Note that the gradient of the roof body 41 is not limited to a downward slope from the front side Y2 to the rear side Y1 in the front-rear direction Y, and may also have a gradient in the left-right direction X. When the gradient of the roof body 41 has a gradient in the left-right direction X, the upper surface of the roofing material 411 is preferably flat. Alternatively, the roof body 41 may be horizontal (flat) without a gradient.

[0023] As shown in Figure 1, the rear frame 412 is provided at the rear end Y1 in the front-rear direction Y of the roof body 41. The rear frame 412 is attached to the rear end Y1 in the front-rear direction Y of the multiple connected roofing materials 411 and extends in the left-right direction X. The rear frame 412 is formed to be open upwards. By being positioned at the rearmost Y1 side in the front-rear direction Y of the multiple roofing materials 411, the rear frame 412 also functions as a gutter, and rainwater flowing on the upper surface of the roof body 4, which is formed with a downward slope descending to the rear Y1 in the front-rear direction Y, flows into the rear frame 412. The water that flows into the rear frame 412 flows from the rear frame 412 into the interior of the column 2 via the guide gutter 42. Alternatively, a gutter extending vertically on the side of the column 2 may be installed to allow water to flow outside the column 2. Also, the gutter may be provided on only one side of the pair of columns 2, rather than both sides.

[0024] The front frame 413 is provided at the front end Y2 in the front-rear direction Y of the roof body 41. The front frame 413 is attached to the front end Y2 in the front-rear direction Y of the multiple connected roofing materials 411 and extends in the left-right direction X. The front frame 413 is made of a single member and covers the longitudinal ends of the three linear lighting sections 43 (described later) attached to the underside of the roof body 41. A pair of side frames 414 covering the roofing materials 411 are provided at both ends of the roof body 41 in the left-right direction X. The side frames 414 are connected to the front frame 413 at the front Y2 and to the rear frame 412 at the rear Y1. The pair of side frames 414 may be a roughly U-shaped cover material or a plate shape, as long as they can cover the ends of the roof body 4 in the left-right direction X.

[0025] As shown in Figures 1 and 2, three lighting units 43 are attached to the underside of the roof body 41. All three lighting units 43 are long, linear lighting units (line lights) extending in the front-to-back direction Y. The lighting units 43 emit light downwards on the roof body 41.

[0026] The three lighting units 43 are arranged at predetermined intervals in the left-right direction X. Each of the three lighting units 43 extends along the longitudinal direction of the roofing material 411 and is attached to a recess 4111 provided on the underside of the roofing material 411, as shown in Figure 3, along the longitudinal direction of the roofing material 411. The recess 4111 is formed in a concave shape on the underside of the roofing material 411, recessing from bottom to top and opening downwards. The recess 4111 extends along the longitudinal direction of the roofing material 411.

[0027] Furthermore, in order to suppress the effects of heat from direct sunlight, a cover material may be attached to cover the upper opening of the roofing material 411 so as to cover the upper side of the recess 4111. Alternatively, insulation material may be placed on top of the recess 4111, and then a cover material may be attached to cover the upper opening of the roofing material 411.

[0028] As shown in Figures 1 and 2, a wiring cable W is connected to each of the three lighting units 43. Power is supplied to the three lighting units 43 via the wiring cables W.

[0029] The wiring structure of the three lighting units 43 in the first embodiment will now be described. As shown in Figures 1 and 2, in the wiring structure of the three lighting units 43 in this embodiment, the wiring cable W is arranged in the following order from the power supply side to the column 23, along at least a part of the side frame 414 on the X2 side in the left-right direction X, and along at least a part of the front frame 413. A connecting section is formed at the connecting portion between the side frame 414 and the front frame 413, through which the wiring cable W is connected, and the connecting section has a guide section (guide hole) that guides the wiring cable W. The guide section may be a hole (guide hole) provided in the side frame 414 or the front frame 413, or an L-shaped corner cap or a guide hole may be provided inside the corner cap.

[0030] Specifically, as shown in Figures 1 and 2, in the wiring structure of the three lighting units 43 of this embodiment, the wiring cable W is passed through the inside of the column 23 from the bottom to the top, introduced from the upper end of the column 23 into the inside of the side frame 414 on the X2 side in the left-right direction X, and as shown in Figure 4, is routed through the inside of the side frame 414 along the front-rear direction Y in which the side frame 414 extends, toward the front Y2 side in the front-rear direction Y, and as shown in Figures 1 and 2, after being routed to the end of the front Y2 side in the front-rear direction Y, at the end of the front Y2 side in the front-rear direction Y, the wiring cable W is passed through a guide part (guide hole) of the connecting part where the side frame 414 and the front frame 413 are connected, bent toward the X1 side in the left-right direction X, and as shown in Figure 5, is routed through the inside of the front frame 413 along the direction in which the front frame 413 extends, toward the X2 side in the left-right direction X. As shown in Figures 1 and 2, the wiring cable W, which is routed through the inside of the front frame 413 from the X2 side to the X1 side in the left-right direction X, branches at the positions where the three lighting units 43 are located and connects to each lighting unit 43.

[0031] The first embodiment described above provides the following advantages. In the carport 1 of the first embodiment, the wiring cable W of the lighting unit 43 is arranged along at least a portion of the column 23, at least a portion of the side frame 414 on the X2 side in the left-right direction X, and at least a portion of the front frame 413. As a result, the wiring cable W can be arranged along at least a portion of the column 23, at least a portion of the side frame 414 on the X2 side in the left-right direction X, and at least a portion of the front frame 413, thus improving the aesthetics of the wiring routing for the lighting unit 43. Furthermore, for example, if the wiring cable W were to be routed along the beam 3, the lighting unit 43 would have to be branched and arranged in the front-rear direction, resulting in poor routing. However, in this embodiment, the wiring cable W is passed through the front frame 413, and the lighting unit 43 is positioned from there in the direction in which the roof material 411 extends, thereby efficiently illuminating the entire depth direction of the roof body 4.

[0032] In this embodiment, at least a portion of the wiring cable W is routed inside the column 23. This hides the vertical wiring from view and prevents it from being visible at eye level. Therefore, the aesthetic appearance is improved.

[0033] In this embodiment, at least a portion of the wiring cable W is routed inside the side frame 414. As a result, the wiring cable W cannot be seen from the side of the roof body 4. Therefore, the aesthetic appearance can be improved.

[0034] In this embodiment, at least a portion of the wiring cable W is routed inside the front frame 413 in the direction in which the front frame 413 extends. As a result, the wiring cable W cannot be seen from the outside of the roof body 4. Therefore, the aesthetic appearance can be improved.

[0035] In this embodiment, the wiring cable W is routed from the power supply side, with at least a portion of it running through the interior of the column 23, the side frame 414, and the front frame 413 in that order, and then connected to the lighting unit 43. This allows the wiring of the wiring cable W to be installed simultaneously with the installation of the roof body 41. Thus, the ease of installation of the wiring cable W can be improved.

[0036] In this embodiment, the front frame 413 covers the longitudinal end of the linear lighting section 43. As a result, the longitudinal end of the linear lighting section 43 is not visible due to the front frame 413, thereby improving the aesthetic appearance.

[0037] In this embodiment, the longitudinal ends of multiple linear lighting units 43 are covered by a single front frame 413. This improves ease of installation because the ends of multiple linear lighting units 43 can be covered by attaching a single front frame 413, and also improves aesthetics because the longitudinal ends of the multiple linear lighting units 43 are not visible due to the front frame 413.

[0038] In this embodiment, a connecting section is formed at the connecting portion between the side frame 414 and the front frame 413, through which the wiring cable W is connected. The connecting section has a guide section (guide hole) that guides the wiring cable W. This makes it easy to route the wiring cable W.

[0039] Next, a second embodiment will be described with reference to Figure 6. In the description of the second embodiment shown in Figure 6, the direction in which the multiple roofing materials 411A (long members) constituting the roof body 41A of the carport 1A in the second embodiment extend is also called the front-rear direction Y (longitudinal direction of the roofing material 411A). In this embodiment, the roof body 4A is inclined in the front-rear direction Y, and in the front-rear direction Y, the upstream side on the left front side in Figure 6 is also called the front side Y2, and the downstream side on the right rear side in Figure 6 is also called the rear side Y1. In addition, the direction in which the multiple roofing materials 411A (long members) constituting the roof body 41A of the roof body 4A are lined up is also called the left-right direction X. In the left-right direction X, one side is called the X1 side, and the other side is called the X2 side.

[0040] The overall structure of the carport 1A (roof structure) of the second embodiment will now be described. As shown in Figure 6, the carport 1A of this embodiment is a carport in which the roof body 41A is supported at the rear side Y1 in the front-rear direction Y by two columns 21A and 22A, and at the front side Y2 in the front-rear direction Y, both ends of the beam 3A in the left-right direction X are supported by two columns 23A and 24A. Furthermore, the carport 1A of this embodiment is configured as a suspension structure in which the roof body 41A is suspended and connected to the lower part (below) of the beam 3A, which is located near the end of the front side Y2 in the front-rear direction Y. As shown in Figure 6, three lighting units 44 are attached to the underside of the roof body 41A. Wiring cables W are connected to the three lighting units 44. Power is supplied to the three lighting units 44 via the wiring cables W. The wiring structure of the three lighting units 44 will be described after the overall structure of the carport 1A is described.

[0041] As shown in Figure 6, the carport 1A of the second embodiment comprises four columns 2A erected on the ground, one beam 3A, a roof body 4A, and three lighting units 44. The columns 2A and beam 3A are formed, for example, from extruded aluminum profiles and have a hollow structure with a hollow cross-section.

[0042] The four columns 2A are formed extending in the vertical direction. The four columns 2A include a column 21A located on the rear side Y1 in the front-to-back direction Y and on the X2 side in the left-to-right direction X, a column 22A located on the rear side Y1 in the front-to-back direction Y and on the X1 side in the left-to-right direction X, a column 23A located on the front side Y2 in the front-to-back direction Y and on the X2 side in the left-to-right direction X, and a column 24A (one-sided column) located on the front side Y2 in the front-to-back direction Y and on the X1 side in the left-to-right direction X. Unless otherwise specified, columns 21A, 22A, 23A, and 24A are simply referred to as "column 2A".

[0043] The roof structure 4A is a suspended structure in which the rear portion Y1 in the front-to-back direction Y of the roof structure 4A is supported by the upper ends of two columns 21A and 22A, and the front portion Y2 in the front-to-back direction Y of the roof structure 4A is directly connected to the lower surface of beam 3A and suspended from the lower part of beam 3A. The rear portion Y1 in the front-to-back direction Y of the roof structure 4A is connected to the upper ends of two columns 21A and 22A, and the front portion Y2 in the front-to-back direction Y is indirectly connected to two columns 23A and 24A via beam 3A. The roof structure 4A is directly connected to beam 3A. Alternatively, the roof structure 4A may be indirectly connected to beam 3A via an indirect member.

[0044] The roof structure 4A has an upper surface that is flat (planar) or uneven, and a lower surface that is flat (planar). The roof structure 4A is formed with a downward slope that descends towards the rear side Y1 in the front-rear direction Y.

[0045] The roof structure 4A comprises a roof body 41A, a plurality of purlins 5 (connecting members), and two beams 6. The roof body 41A comprises a plurality of roofing materials 411A (long members), a rear frame 412A, a front frame 413A (one-side end frame), and a pair of side frames 414A.

[0046] Multiple roofing materials 411A extend in the front-to-back direction Y, which intersects the direction in which the purlins 5 extend. Multiple roofing materials 411A are arranged in a row in the left-to-right direction X, where the purlins 5 (described later) extend, and are fitted together and connected to one another. Each of the multiple roofing materials 411A extends parallel to the front-to-back direction Y of the carport 1A and has a predetermined thickness. The roof body 41A is constructed by arranging and connecting multiple parallel roofing materials 411A. All of the multiple roofing materials 411A are formed from extruded aluminum profiles.

[0047] Multiple roofing materials 411A are formed, for example, with an upper surface that is flat or uneven, and an lower surface that is flat. As a result, the roof body 41A is made up of multiple roofing materials 411A connected together, and as a whole, the lower surface is formed flat, and the upper surface is formed flat or uneven.

[0048] The multiple roofing materials 411A that make up the roof body 41A may be configured as hollow structures with hollow sections, or as solid structures with no upper surface of the hollow section and an open upper side. The upper surface of the roof body 41A may also be formed flat (planar).

[0049] The roof body 41A is formed with a downward slope in the front-rear direction Y, from the front side Y2 to the rear side Y1, as the roofing material 411A extends in the front-rear direction Y. As a result, the roof body 41A is formed with a front-rear slope that slopes downward from the front side Y2 to the rear side Y1 in the front-rear direction Y. In this embodiment, for example, the inclination angle of the roof body 41A in the front-rear direction Y is set to about 1° to 6°. In addition, the roof body 41A is not inclined in the left-right direction X, and extends horizontally, for example. Note that the slope of the roof body 41A is not limited to a downward slope from the front side Y2 to the rear side Y1 in the front-rear direction Y, and may also have a slope in the left-right direction X. When the slope of the roof body 41A has a slope in the left-right direction X, it is preferable that the upper surface of the roofing material 411A is flat. Alternatively, the roof body 41A may be horizontal (flat) without a slope.

[0050] The rear frame 412A is installed at the rear end Y1 in the front-rear direction Y of the roof body 41A. The rear frame 412A is attached to the rear end Y1 in the front-rear direction Y of the multiple connected roofing materials 411A and extends in the left-right direction X. The rear frame 412A is formed to be open upwards. By being positioned at the rearmost Y1 side in the front-rear direction Y of the multiple roofing materials 411A, the rear frame 412A also functions as a gutter, and rainwater flowing on the upper surface of the roof body 4A, which is formed with a downward slope descending to the rear end Y1 in the front-rear direction Y, flows into the rear frame 412A. The water that flows into the rear frame 412A flows from the rear frame 412A into the interior of the column 2A.

[0051] The front frame 413A is provided at the front end Y2 in the front-rear direction Y of the roof body 41A. The front frame 413A is attached to the front end Y2 in the front-rear direction Y of the multiple connected roofing materials 411A and extends in the left-right direction X. The front frame 413A is made of a single member and covers the longitudinal ends of the three linear lighting sections 44 (described later) attached to the underside of the roof body 41A. A pair of side frames 414A that cover the roofing materials 411A are provided at both ends in the left-right direction X of the roof body 41A. The side frames 414A are connected to the front frame 413A at the front Y2 and to the rear frame 412A at the rear Y1. The pair of side frames 414A may be a roughly U-shaped cover material or a plate shape, as long as they can cover the left-right ends of the roof body 4A.

[0052] Multiple purlins 5 are positioned on the upper surface of the roof body 41A and connected to the upper surface of the roof body 41A. Multiple purlins 5 are arranged in a line with spacing in the front-rear direction Y. Multiple purlins 5 are formed extending in the left-right direction X, which is the direction in which the roof material 411A extends, and extend in the left-right direction X across the multiple roof material 411A on the upper surface of the multiple roof material 411A. In this embodiment, three purlins 5 are provided. The number of purlins 5 is not limited.

[0053] Multiple purlins 5 connect multiple roofing materials 411A that make up the roof body 41A. Each of the multiple purlins 5 is fixed to each of the multiple roofing materials 411A by fastening members such as screws. Because multiple purlins 5 connect and fix multiple roofing materials 411A, the strength of the roof body 41A can be improved.

[0054] The two girders 6 are positioned above the roof body 41A, on the upper surface of the roof body 41A, at a position outside the roof body 41A in the left-right direction X. The two girders 6 each extend in the front-rear direction Y, which intersects the direction in which the beams 3 and purlins 5 extend.

[0055] The two girders 6 are positioned on the upper surface of the roof body 41A, outside the X1 and X2 ends of the purlins 5 in the left-right direction X. The longitudinal ends (outer ends in the left-right direction X) of the purlins 5 are positioned opposite each other on the inner sides of the two girders 6 in the left-right direction X. The longitudinal ends of the purlins 5 are connected to the inner sides of the girders 6 in the left-right direction X.

[0056] Both girders 6 have their undersides fixed to the upper surface of the roof body 41A, and their front ends Y2 in the front-rear direction Y are positioned to the side of the rear end Y1 in the front-rear direction Y of the beam 3A, and connected to the side of the rear end Y1 in the front-rear direction Y of the beam 3A. The two girders 6 may be directly connected to the beam 3A, or they may be connected to the beam 3A via connecting members (not shown). The two girders 6 connect multiple purlins 5, each made up of multiple roofing materials 411A, thereby reinforcing the strength of the roof body 41A so that the roofing materials 411A do not sag, and improving the strength of the roof body 41A.

[0057] Of the four columns 2A, the two columns 21A and 22A, which are positioned on the rear side Y1 in the front-to-back direction Y of the roof body 41A, are positioned near the inside of the corner portion on the rear side Y1 in the front-to-back direction Y of the roof body 41A.

[0058] The two columns 21A and 22A are positioned apart in the left-right direction X at the rear end Y1 of the carport 1A in the front-rear direction Y. The two columns 21A and 22A each extend in the vertical direction. The two columns 21A and 22A are positioned to penetrate the roof body 41A vertically at the rear end Y1 of the carport 1A in the front-rear direction Y. The upper ends of the two columns 21A and 22A are both connected to the lower surface of the beam 6 which is positioned on the upper surface of the roof body 41 above the roof body 41. Regarding the connection between the roof body 41A and the columns 21A and 22A, in addition to connecting the upper ends of the columns 21A and 22A to the underside of the girders 6 by passing them through the roof body 41A, the upper ends of the columns 21A and 22A may also be connected to the girders 6 located on the upper surface of the roof body 41A by using connecting members (not shown) that protrude downward from the underside of the girders 6 located on the upper surface of the roof body 41A, and fixing the connecting members protruding downward from the underside of the girders 6 to the upper ends of the columns 21A and 22A.

[0059] As a result, the two columns 21A and 22A, positioned at the rear end Y1 of the carport 1A in the front-to-back direction Y, are connected to the underside of the rear end Y1 of the beam 6, penetrating the roof body 41A vertically, thereby supporting the rear end Y1 portion of the beam 6 from below. Thus, the rear Y1 portion of the roof body 41A in the front-to-back direction Y is supported by the upper ends of the two columns 21A and 22A via the beam 6.

[0060] Of the four columns 2A, the two columns 23A and 24A, which are positioned on the front side Y2 in the front-to-back direction Y of the roof body 41A, are positioned on the outside in the left-to-right direction X of the roof body 41A on the front side Y2 in the front-to-back direction Y of the roof body 41A.

[0061] The two columns 23A and 24A are positioned at a distance in the left-right direction X, near the front end Y2 of the carport 1A in the front-rear direction Y. The two columns 23A and 24A are positioned on the outer side of the roof body 41A in the left-right direction X, close to the side of the roof body 41A. The two columns 23A and 24A each extend in the vertical direction. Beam 3A is connected to the upper ends of the two columns 23A and 24A.

[0062] The two columns 23A and 24A are positioned near the front end Y2 in the front-to-back direction Y of the roof body 41A, and are located on the outer sides of both ends in the left-to-right direction X of the roof body 41A. The positions of the columns 23A and 24A in the left-to-right direction X (the direction in which the beam 3A extends) can be set to any position in the left-to-right direction X of the roof body 41A, away from both ends in the left-to-right direction X of the roof body 41A, depending on the surrounding conditions.

[0063] Beam 3A is positioned above the roof body 41A and on the upper surface of the roof body 41A. Beam 3 extends in the left-right direction X. Both ends of beam 3A in the longitudinal direction are connected to the upper ends of two columns 23A and 24A. The lower surface of the lower part of beam 3A is connected to the roof body 41A. If columns 23A and 24A can be installed at any position in the left-right direction X along which beam 3A extends, away from both ends of the roof body 41A in the left-right direction X, then beam 3A can be extended in the left-right direction X by extending beam 3A in that direction. When beam 3A is extended in the left-right direction X, in the wiring structure of the three lighting units 44 described later, the wiring cable W is routed in the order of column 24A, beam 3A, side frame 414A, front frame 413A, and lighting unit 44, and the wiring cable W is routed along beam 3A in the middle of the wiring.

[0064] As shown in Figure 6, three lighting units 44 are attached to the underside of the roof body 41A. All three lighting units 44 are long, linear lighting units (line lights) extending in the front-to-back direction Y. The lighting units 44 emit light downwards on the roof body 41A.

[0065] The three lighting units 44 are arranged at predetermined intervals in the left-right direction X. Each of the three lighting units 44 extends along the longitudinal direction of the roofing material 411A and is attached to the underside of the roofing material 411A along the longitudinal direction of the roofing material 411A.

[0066] Each of the three lighting units 44 is connected to a wiring cable W. Power is supplied to the three lighting units 44 via the wiring cables W.

[0067] The wiring structure of the three lighting units 44 in the second embodiment will now be described. As shown in Figure 6, in the wiring structure of the three lighting units 44 in this embodiment, the wiring cable W is arranged in the following order from the power supply side to which power is supplied, along at least a part of the column 24A, at least a part of the side frame 414A on the X1 side in the left-right direction X, and at least a part of the front frame 413A. A connecting section is formed at the connecting portion between the side frame 414A and the front frame 413A, through which the wiring cable W is connected, and the connecting section has a guide section (guide hole) that guides the wiring cable W.

[0068] Specifically, as shown in Figure 6, in the wiring structure of the three lighting units 44 of this embodiment, the wiring cable W is passed through the inside of the column 24A from the bottom to the top, introduced from the upper end of the column 24A into the inside of the side frame 414A on the X1 side in the left-right direction X, routed through the inside of the side frame 414A along the front-rear direction Y in which the side frame 414A extends toward the front Y2 side in the front-rear direction Y, routed to the end of the front Y2 side in the front-rear direction Y, and then passed through a guide part (guide hole) of the connecting part where the wiring cable W is connected at the connecting part between the side frame 414A and the front frame 413A, bent toward the X2 side in the left-right direction X, and routed through the inside of the front frame 413A along the direction in which the front frame 413A extends toward the X1 side in the left-right direction X. The wiring cable W, which is routed through the inside of the front frame 413A from side X1 to side X2 in the left-right direction X, branches off at the positions where the three lighting units 44 are located, and connects to each lighting unit 44 along the way as it is routed through the inside of the front frame 413A from side X1 to side X2 in the left-right direction X.

[0069] The second embodiment described above provides the following advantages. In the carport 1A of the second embodiment, the wiring cable W of the lighting unit 44 is arranged along at least a portion of the column 24A, at least a portion of the side frame 414A on the X1 side in the left-right direction X, and at least a portion of the front frame 413A. As a result, the wiring cable W can be arranged along at least a portion of the column 24A, at least a portion of the side frame 414A on the X1 side in the left-right direction X, and at least a portion of the front frame 413A, thus improving the aesthetics of the wiring routing for the lighting unit 44. Furthermore, for example, if the wiring cable W were to be routed to the beam 3A or purlin 5, the lighting unit 44 would have to be branched and arranged in the front-rear direction, resulting in poor routing. In contrast, in this embodiment, the wiring cable W is passed through the front frame 413A, and the lighting unit 44 is positioned from there in the direction in which the roofing material 411A extends, thereby efficiently illuminating the entire depth direction of the roof body 4A.

[0070] In this embodiment, at least a portion of the wiring cable W is routed inside the column 24A. This prevents the vertical wiring from being visible by routing it through the column 24A, thus concealing it from view at eye level. Therefore, the aesthetic appearance can be improved.

[0071] In this embodiment, at least a portion of the wiring cable W is routed inside the side frame 414A. As a result, the wiring cable W cannot be seen from the side of the roof body 4A. Therefore, the aesthetic appearance can be improved.

[0072] In this embodiment, at least a portion of the wiring cable W is routed inside the front frame 413A in the direction in which the front frame 413A extends. As a result, the wiring cable W cannot be seen from the outside of the roof body 4A. Therefore, the aesthetic appearance can be improved.

[0073] In this embodiment, the wiring cable W is routed from the power supply side, with at least a portion of it running through the interior of the column 24A, the side frame 414A, and the front frame 413A in that order, and then connected to the lighting unit 44. This allows the wiring of the wiring cable W to be installed simultaneously with the installation of the roof body 41A. Thus, the ease of installation of the wiring cable W can be improved.

[0074] In this embodiment, the front frame 413A covers the longitudinal end of the linear lighting section 44. As a result, the longitudinal end of the linear lighting section 44 is not visible due to the front frame 413A, thereby improving the aesthetic appearance.

[0075] In this embodiment, the longitudinal ends of multiple linear lighting units 44 are covered by a single front frame 413A. This improves ease of installation because the ends of multiple linear lighting units 44 can be covered by attaching a single front frame 413A, and also improves aesthetics because the longitudinal ends of the multiple linear lighting units 44 are not visible due to the front frame 413A.

[0076] In this embodiment, a connecting section is formed at the joint between the side frame 414A and the front frame 413A, through which the wiring cable W is connected. The connecting section has a guide section (guide hole) that guides the wiring cable W. This makes it easy to route the wiring cable W.

[0077] Next, the third embodiment will be described with reference to Figures 7 to 10. The carport 1B (roof structure) of the third embodiment has two linear lighting units 45 and wiring for the lighting units 45 instead of the three linear lighting units 43 and wiring for the lighting units 43 of the first embodiment shown in Figures 1 to 5. In the carport 1B of the third embodiment, the configuration other than the two linear lighting units 45 and wiring is the same as that of the carport 1 of the first embodiment. For configurations not described in the third embodiment, the description of the first embodiment can be used as a reference.

[0078] As shown in Figures 7 and 8, in the third embodiment, two lighting units 45 are attached to the underside of the roof body 41. Both lighting units 45 are long, linear lighting units (line lights) extending in the left-right direction X. The two lighting units 45 emit light downwards on the roof body 41.

[0079] The two lighting units 45 are positioned at both ends of the roof body 41 in the front-rear direction Y. As shown in Figures 7 and 8, the lighting unit 45 positioned at the front Y2 in the front-rear direction Y extends along the longitudinal direction of the front frame 413 and is attached to a recess 4131 provided on the lower surface of the front frame 413, as shown in Figure 9. The recess 4131 is formed in a concave shape on the lower surface of the front frame 413, recessing from bottom to top and opening downwards. The recess 4131 extends in the longitudinal direction of the front frame 413. As shown in Figures 7 and 8, the lighting unit 45 positioned at the rear Y1 in the front-rear direction Y extends along the longitudinal direction of the rear frame 412 and is attached to the lower surface of the rear frame 412, along the longitudinal direction of the rear frame 412. Of the two lighting units 45, the lighting unit 45 located at the rear Y1 in the front-rear direction Y is, although not shown in the figure, attached to a recess (not shown) on the lower surface of the rear frame 412 along the longitudinal direction of the rear frame 412, similar to the front frame 413.

[0080] As shown in Figures 7 and 8, a wiring cable W is connected to each of the two lighting units 45. Power is supplied to the two lighting units 45 via the wiring cable W.

[0081] The wiring structure of the two lighting units 45 in the third embodiment will now be described. As shown in Figures 7 and 8, in the wiring structure of the two lighting units 45 in this embodiment, the wiring cable W is arranged along at least a portion of the column 23 and at least a portion of the side frame 414 on the X2 side in the left-right direction X.

[0082] Specifically, as shown in Figures 7 and 8, in the wiring structure of the two lighting units 45 of this embodiment, the wiring cable W is passed from the power supply side, through the inside of the column 23 from the bottom to the top, and introduced from the upper end of the column 23 into the inside of the side frame 414 on the X2 side in the left-right direction X. Inside the side frame 414, it branches to the front Y2 and rear Y1 in the front-rear direction Y, and is wired along the front-rear direction Y to the front Y2 and rear Y1, respectively, in the front-rear direction Y to which the side frame 414 extends.

[0083] The wiring cable W, which branches from the upper end of the column 23 to the front side Y2 in the front-rear direction Y, is routed along the side frame 414 on the X2 side in the left-right direction X, as shown in Figures 7 and 8, and through the interior of the side frame 414 on the X2 side in the left-right direction X, as shown in Figure 10, to the end of the front side Y2 in the front-rear direction Y, as shown in Figures 7 and 8, and at the end of the front side Y2 in the front-rear direction Y, it is connected to the lighting unit 45 located on the front frame 413.

[0084] The wiring cable W, which branches from the upper end of the column 23 to the rear side Y1 in the front-rear direction Y, is routed along the side frame 414 on the X2 side in the left-right direction X, through the inside of the side frame 414 on the X2 side in the left-right direction X, to the end of the rear side Y1 in the front-rear direction Y, and at the end of the rear side Y1 in the front-rear direction Y, it is connected to the lighting unit 45 located on the rear frame 412.

[0085] In the third embodiment, the wiring cable W can be arranged in this order along at least a portion of the column 23 and at least a portion of the side frame 414 on the X2 side in the left-right direction X, thereby improving the aesthetic design with respect to the routing of the wiring for the lighting unit 45.

[0086] Next, the fourth embodiment will be described with reference to Figure 11. The carport 1C (roof structure) of the fourth embodiment has two linear lighting units 46 and wiring for the lighting units 46 instead of the three linear lighting units 44 and wiring for the lighting units 44 of the second embodiment shown in Figure 6. In the carport 1C of the fourth embodiment, the configuration other than the two linear lighting units 46 and wiring is the same as that of the carport 1A of the second embodiment. Configurations not described in the fourth embodiment can be explained by referring to the description of the second embodiment.

[0087] As shown in Figure 11, in the fourth embodiment, two lighting units 46 are attached to the underside of the roof body 41A. Both lighting units 46 are long, linear lighting units (line lights) extending in the left-right direction X. The two lighting units 46 emit light downwards on the roof body 41.

[0088] The two lighting units 46 are positioned at both ends of the roof body 41A in the front-rear direction Y. As shown in Figure 11, the two lighting units 46 each extend along the longitudinal direction of the front frame 413A or the rear frame 412A and are attached to the underside of the front frame 413A and the rear frame 412A, respectively.

[0089] As shown in Figure 11, a wiring cable W is connected to each of the two lighting units 46. Power is supplied to the two lighting units 46 via the wiring cables W.

[0090] The wiring structure of the two lighting units 46 in the fourth embodiment will now be described. As shown in Figure 11, in the wiring structure of the two lighting units 46 in this embodiment, the wiring cable W is arranged along at least a portion of the column 24A and at least a portion of the side frame 414A on the X1 side in the left-right direction X.

[0091] Specifically, as shown in Figure 11, in the wiring structure of the two lighting units 46 of this embodiment, the wiring cable W is passed from the power supply side, through the inside of the column 24A from the bottom to the top, and introduced from the upper end of the column 24A into the inside of the side frame 414A on the X1 side in the left-right direction X. Inside the side frame 414A, it branches to the front Y2 and rear Y1 in the front-rear direction Y, and is wired along the front-rear direction Y on which the side frame 414A extends, toward the front Y2 and rear Y1 respectively.

[0092] As shown in Figure 11, the wiring cable W that branches from the upper end of column 24A to the front Y2 in the front-rear direction Y is routed along the side frame 414A on the X1 side in the left-right direction X, through the inside of the side frame 414A on the X1 side in the left-right direction X, to the end of the front Y2 in the front-rear direction Y, and is connected to the lighting unit 46 located on the front frame 413A at the end of the front Y2 in the front-rear direction Y.

[0093] As shown in Figure 11, the wiring cable W that branches from the upper end of column 24A to the rear Y1 in the front-rear direction Y is routed along the side frame 414A on the X1 side in the left-right direction X, through the inside of the side frame 414A on the X1 side in the left-right direction X, to the end of the rear Y1 in the front-rear direction Y, and is connected to the lighting unit 46 located on the rear frame 412A at the end of the rear Y1 in the front-rear direction Y.

[0094] In the fourth embodiment, the wiring cable W can be arranged in this order along at least a portion of the column 24A and at least a portion of the side frame 414A on the X1 side in the left-right direction X, thereby improving the aesthetic design of the wiring for the lighting unit 46.

[0095] Although a preferred embodiment of the roof structure of this disclosure has been described above, this disclosure is not limited to the embodiment described above and can be modified as appropriate.

[0096] In the above embodiment, the wiring cable W was passed through columns 23 and 24A, but this is not the case. In the column configuration of the embodiment, the wiring cable W may be passed through any of the columns. Also, the number of columns is not limited and can be changed as appropriate. Furthermore, the number of linear lighting units is not limited and may be one or multiple.

[0097] In the above embodiment, the lighting units 43, 44, 45, and 46 were configured as line lights extending in the front-to-back direction Y or the left-to-right direction X, for example, but are not limited to this. For example, the lighting units may be configured as spotlights composed of point light sources.

[0098] The wiring structure of this disclosure can be applied to areas other than lighting. In this embodiment, the wiring structure of a lighting unit was described as an example, but it is not limited to this, and the wiring structure of this disclosure can also be applied to wiring and power supply to other electrical equipment installed on a roof, such as security cameras, motion sensors, speakers, and displays.

[0099] Furthermore, in the configurations of the second and fourth embodiments, purlins 5 (connecting members) are provided to connect multiple roofing materials 411A. In the configurations of the first and third embodiments, purlins 5 (connecting members) are not provided to connect multiple roofing materials 411A, but the configurations are not limited to these, and purlins 5 (connecting members) may also be provided in the configurations of the first and third embodiments to connect multiple roofing materials 411A.

[0100] In the second embodiment described above, the front columns (columns 23A and 24A) may also be positioned under the roof body 4A, similar to the rear columns (21A and 22A). In this case, the girders 6 may be extended to the position of the front columns (columns 23A and 24A), and the upper ends of the columns (columns 23A and 24A) may be connected to the girders 6. The connection between the front columns (columns 23A and 24A) and the girders 6 may be the same as the connection between the rear columns (21A and 22A) and the girders 6. In this case, beams 3A may be left in the same configuration as the purlins 5, or they may be omitted. In this case, the wiring structure for the wiring cables W is such that the wiring cables W are routed from the upper end of the column or from the side of the column to the side frame.
