DETAILED DESCRIPTION OF THE INVENTION

[0008] An embodiment of the present invention will be described with reference to the drawings.

[0009] The roof structure 10 according to this embodiment is suspended below beams 70 to block direct sunlight, rainwater, and the like. For example, it can be used as a building eaves, a carport, a roof for an outdoor walkway between buildings, a bus stop roof, or a bicycle parking area roof. Note that, although this embodiment will be described taking as an example a case in which the beams 70 protrude horizontally from the wall surface 71, the form of the beams 70 is not limited to this. For example, the roof structure 10 may be installed on a beam 70 protruding from a column, or on a beam 70 supported on both sides. As shown in FIG. 1, the roof structure 10 according to this embodiment includes a roof body 11, a gutter bracket 30, and a gutter 32.

[0010] The roof body 11 is formed in a plate shape and is inclined so that one end is lower. This roof body 11 is formed by arranging multiple roofing materials 12 in a predetermined direction and joining them together. The width of the roof body 11 can be adjusted by increasing or decreasing the number of roofing materials 12 that are connected. The roofing material 12 in this embodiment is a hollow aluminum material. All of the multiple roofing materials 12 are formed to the same size, and the height dimensions (thickness) at the top and bottom are also set to be approximately the same.

[0011] The roofing material 12 has a cross-sectional shape, for example, as shown in FIG. 4(a), and adjacent roofing materials 12 are joined to each other by engagement between a first joint 50 provided on one of the roofing materials 12 and a second joint 60 provided on the other. Note that while the roofing material 12 shown in FIG. 4(a) has both a first joint 50 and a second joint 60, it is sufficient for the roofing material 12 to have at least one of the first joint 50 and the second joint 60. In other words, the roofing material 12 placed in the middle of the roof main body 11 (in the example of FIG. 5, the roofing material 12 other than the leftmost one) has both the first joint 50 and the second joint 60, but the roofing material 12 placed at both ends of the roof main body 11 (in the example of FIG. 5, the leftmost roofing material 12) is sufficient to have only one of the first joint 50 and the second joint 60.

[0012] This roofing material 12 comprises an upper plate portion 40 and a lower plate portion 41 that are parallel to each other, with a hollow space between these upper plate portion 40 and lower plate portion 41. A plurality of vertical walls extending in the vertical direction are provided between the upper plate portion 40 and the lower plate portion 41. In this embodiment, these vertical walls include side wall portions 42 on both the left and right sides, and an intermediate wall portion 43 is provided between the side wall portions 42.

[0013] The first joint portion 50 is a modified, generally U-shaped portion that opens laterally. The first joint portion 50 includes a first side wall portion 52 that is the side wall portion 42 that defines the first joint portion 50, a first upper protrusion 51 that protrudes laterally beyond the first side wall portion 52 by extending the upper plate portion 40, and a first lower protrusion 53 that protrudes laterally beyond the first side wall portion 52 by extending the lower plate portion 41. A rotation shaft portion 51a is formed at the tip of the first upper protrusion portion 51. At least the lower surface of the rotation shaft portion 51a is formed as a curved surface (preferably a semi-cylindrical curved surface).

[0014] An arc-shaped portion 52a is provided at the upper end of the first side wall portion 52 so as to be continuous with the lower surface of the upper plate portion 40. The arc-shaped portion 52a is formed in an arc shape that follows the circumferential surface of the rotation shaft portion 51a. With this configuration, an arc-shaped guide groove 52b is formed between the rotation shaft portion 51a and the arc-shaped portion 52a, and the rotation shaft portion 51a is disposed above this guide groove 52b.

[0015] Furthermore, a straight portion 52d extending substantially vertically downward is connected to the first side wall portion 52 below the guide groove 52b (arcuate portion 52a). An inclined portion 52c is connected below this straight portion 52d. This inclined portion 52c is inclined inward (opposite the opening direction of the first joint portion 50) as it extends downward.

[0016] The first lower protrusion 53 includes a flat plate portion 53a continuous with the lower plate portion 41, a rising portion 53b extending upward from the end of the flat plate portion 53a, and an arc-shaped curved piece 53c extending diagonally upward from the upper end of the rising portion 53b. The curved piece 53c is formed in an arc shape centered on the rotation shaft 51a below the rotation shaft 51a. Note that the curved piece 53c does not have to be completely arc-shaped centered on the rotation shaft 51a, as long as it has a shape that follows the outer periphery of the rotation shaft 51a.

[0017] The space surrounded by the first side wall portion 52 and the first lower protrusion portion 53 is groove-shaped and opens upward, forming an intermediate gutter portion 54 for receiving water that seeps in through the joined joints. This intermediate gutter portion 54 can receive water that flows in the longitudinal direction D of the roofing material 12. In this embodiment, a portion of the first side wall portion 52 is formed at an angle (having an inclined portion 52c), thereby ensuring a large volume for the intermediate gutter portion 54 (the maximum volume of water that can be received in the gutter). Furthermore, because the curved piece 53c protrudes sideways in an arc, the volume of the intermediate gutter portion 54 is further increased.

[0018] The second joint portion 60 joined to the first joint portion 50 is also a modified, generally U-shaped portion that opens laterally. The second joint portion 60 includes a second side wall portion 62 that is the side wall portion 42 that defines the second joint portion 60, a second upper protrusion portion 61 that protrudes laterally beyond the second side wall portion 62 by extending the upper plate portion 40, and a second lower protrusion portion 63 that protrudes laterally beyond the second side wall portion 62 by extending the lower plate portion 41.

[0019] A pivot receiving portion 61a is formed at the tip of the second upper protrusion 61. The pivot receiving portion 61a has an arc-shaped inner circumferential surface that opens upward. This pivot receiving portion 61a can support the pivot shaft portion 51a of the first joint portion 50 from below. This pivot receiving portion 61a can rotatably support the placed pivot shaft portion 51a. Furthermore, this pivot receiving portion 61a can be inserted into the guide groove 52b of the first joint portion 50. Because the guide groove 52b has the same arc shape as the pivot receiving portion 61a, it can rotatably support the inserted pivot receiving portion 61a. With this configuration, the first joint portion 50 and the second joint portion 60 can be rotated relative to each other, making it easy to join the roof material 12.

[0020] The second side wall 62 also includes a support groove 62a into which the tip of the curved piece 53c of the first joint 50 is inserted. When the first joint 50 and the second joint 60 are joined, the curved piece 53c is inserted into the support groove 62a, allowing it to withstand loads in the vertical and horizontal directions, thereby increasing the strength of the joint. In other words, support is provided at two points: the pivot receiver 61a inserted into the guide groove 52b and the curved piece 53c inserted into the support groove 62a. This provides reinforcement against loads in the vertical and horizontal directions. Furthermore, as shown in FIG. 4(c), a labyrinth shape is formed at the tip of the intermediate gutter 54, preventing water from leaking to the underside of the roofing material 12. The support groove 62a is slightly wider than the thickness of the curved piece 53c, allowing the curved piece 53c to be loosely fitted within the support groove 62a. In other words, the curved piece 53c is inserted into the support groove 62a with a gap around it. It is desirable that the support groove 62a and the curved piece 53c are formed so that they do not come into contact with each other when the first joint portion 50 and the second joint portion 60 are rotated to join together. By loosely fitting the curved piece 53c into the support groove 62a in this way, no force is required when joining or detaching the roof material 12, making the work easy.

[0021] Additionally, an upwardly bent erected portion 63a is formed at the tip of the second lower protrusion 63. This erected portion 63a abuts against the rising portion 53b when the first joint 50 and the second joint 60 are joined. The abutment of this erected portion 63a against the rising portion 53b supports adjacent roofing materials 12 in a flat state (i.e., the undersides 11a of all roofing materials 12 are flat). Furthermore, the formation of this erected portion 63a creates a groove-shaped space surrounded by the second sidewall 62 and the second lower protrusion 63, forming a secondary gutter 64. As shown in FIG. 4(c), this secondary gutter 64 is positioned below and overlaps the intermediate gutter 54, and can catch water that leaks outside the intermediate gutter 54. The provision of this secondary gutter 64 allows water to be caught even if it infiltrates behind the curved piece 53c.

[0022] As shown in FIG. 4(b), the first joint portion 50 and the second joint portion 60 can be joined by rotating one of the roof materials 12 from above with the engagement point as a fulcrum.

[0023] In the example shown in FIG. 4(b), the second joint portion 60 is tilted and inserted from above into the first joint portion 50. At this time, the pivot receiving portion 61a fits into and catches in the guide groove 52b. After that, the roof material 12 on the second joint portion 60 side is pivoted downward using the engagement point (pivot shaft portion 51a) as a fulcrum, and the erect portion 63a abuts against the rising portion 53b. By this operation, the two adjacent roof materials 12 are joined flatly to each other. At this time, the curved piece 53c is automatically inserted into the support groove 62a.

[0024] In this way, in the roofing material 12 of this embodiment, the undersides of adjacent roofing materials 12 can be maintained in a flat state simply by engaging the first joint portion 50 and the second joint portion 60.

[0025] In this example, the roof material 12 on the second joint 60 side is inserted at an angle and rotated downward, but this is not limited to this, and adjacent roof materials 12 can also be joined by inserting the roof material 12 on the first joint 50 side at an angle and rotating it downward.

[0026] Furthermore, the first joint portion 50 and the second joint portion 60 are formed over the entire length of the roofing material 12 in the longitudinal direction D. Therefore, after the first joint portion 50 and the second joint portion 60 are joined, the roofing material 12 can be slid in the longitudinal direction D of the roofing material 12. Therefore, after the roofing materials 12 are joined, it is easy to align their positions in the longitudinal direction D.

[0027] To remove the roofing materials 12 joined as described above, the roofing materials 12 can be rotated in the opposite direction (upward). That is, from the state in which the two roofing materials 12 are engaged as shown in Figure 4(c), by rotating one of the roofing materials 12 upward using the engagement point as a fulcrum as shown in Figure 4(b), the engagement between the adjacent roofing materials 12 can be released.

[0028] 1 and 2, the roof body 11 according to this embodiment is provided with tip members 13 at both ends of the roof material 12 in the longitudinal direction D. The tip members 13 are attached across the tips of multiple roof materials 12. These tip members 13 may be used to connect multiple roof materials 12 to each other at their ends.

[0029] As shown in Figure 6, the tip member 13 according to this embodiment is fixed to the upper surface of the roof main body 11 and extends so that its tip hangs down. The tip member 13 extends below the underside 11a of the roof material 12. This allows the tip member 13 to cover the edge of the roof material 12, and also allows rainwater that has flowed down the upper surface of the roof material 12 to be guided downward along the tip member 13. A horizontal gutter 32 is provided vertically below the lower end of this tip member 13, so that it can catch rainwater that falls from the tip member 13. It is not necessary to provide the horizontal gutter 32 below the tip members 13 on both sides; it is sufficient that it is provided below at least the tip member 13 that is tilted lower.

[0030] 2 and 3, a small palate 14 is attached to each end of the distal end member 13. The small palate 14 closes the openings at each end of the distal end member 13.

[0031] As shown in Figures 1 and 5, this roof body 11 is suspended and supported by beams 70 using hanging parts 70a, fixing means 22, mounting members 25, spacers 26, bolts 27, plates 28, nuts 29, etc.

[0032] Hanging portion 70a is a plate-like member that protrudes downward from beam 70. Hanging portion 70a is, for example, a metal plate fixed to beam 70 by welding. Roof body 11 is suspended below hanging portion 70a. Holes for attaching fastening means 22, such as bolts and nuts, are formed through hanging portion 70a, and mounting members 25, described below, are attached using fastening means 22. In this embodiment, as shown in FIG. 1 , hanging portions 70a of different lengths are used in combination at the front and rear of roof body 11. Specifically, hanging portion 70a located at the tip end of roof body 11 is shorter than hanging portion 70a located at the base end of roof body 11. This makes it possible to change the height of the mounting positions of mounting members 25, thereby allowing roof body 11 to be tilted so that the tip end is higher.

[0033] Mounting member 25 is a long member that extends in a direction perpendicular to the longitudinal direction D of roof material 12. Mounting member 25 in this embodiment is a metal angle member as shown in FIG. 1. This mounting member 25 includes a vertical piece 25a that is attached to hanging portion 70a, and a horizontal piece 25b to which bolts 27, described later, are attached. This mounting member 25 is attached to hanging portion 70a so that vertical piece 25a is approximately vertical and horizontal piece 25b is approximately horizontal. This mounting member 25 has a length that is approximately equal to the width of roof main body 11, and is positioned so as to span all of the roof materials 12. Roof materials 12 are attached to the lower part of this mounting member 25 with bolts 27, described later.

[0034] The spacer 26 is a cylindrical member that is placed between the mounting member 25 and the roofing material 12. There is no particular restriction on the material of the spacer 26, but it can be made of metal, resin, or the like. A through hole is formed inside the spacer 26, through which a bolt 27, which will be described later, can be inserted. By providing this spacer 26, the mounting member 25 and the roofing material 12 can be fixed with a gap between them.

[0035] Bolt 27 passes through the interior of spacer 26 and is used to secure mounting member 25 and roof material 12 together. The tip of bolt 27 is fastened to nut 29 inside roof material 12. When bolt 27 and nut 29 are fastened together, as shown in FIG. 5, the upper edge of spacer 26 abuts against the underside of mounting member 25 (horizontal piece 25b), and the lower edge of spacer 26 abuts against the upper surface of roof material 12. This creates a space between mounting member 25 and roof material 12 that is equal to the length of spacer 26.

[0036] Plate 28 is a plate-like member that is inserted into the hollow portion of roofing material 12. By attaching nuts 29 to the tips of bolts 27 that pass through plate 28, the fastening force of nuts 29 can be received by plate 28. This makes it possible to prevent deformation due to fastening without increasing the thickness of roofing material 12.

[0037] In this embodiment, bolts 27 are not attached to all roofing materials 12. Using Figure 5 as an example, bolts 27 are attached to the roofing material 12 on the far left, but no bolts 27 are attached to the roofing material 12 to the right. In this way, by fixing only some of the roofing materials 12 directly to the beams 70 and fixing the other roofing materials 12 indirectly to the beams 70, the number of parts and labor costs can be reduced.

[0038] As shown in Figure 6, the gutter bracket 30 is a component that is attached to the flat underside 11a of the roof main body 11. The gutter bracket 30 according to this embodiment is a short, bent plate-like component as shown in Figures 7 and 8. The gutter bracket 30 according to this embodiment is made of a bent metal plate material. This gutter bracket 30 includes a roof mounting portion 30a, a first gutter mounting portion 30b, and a second gutter mounting portion 30e.

[0039] The roof mounting portion 30a is a portion that is attached by abutting against the underside 11a of the roof main body 11. This roof mounting portion 30a is inclined along the roof slope. In other words, when attached to the underside 11a of the roof main body 11, it is fixed in an inclined state rather than horizontally. This roof mounting portion 30a is screw-fastened to the roof main body 11 by a bracket mounting means 31. The bracket mounting means 31 in this embodiment is a screw (bolt) that is inserted from the underside 11a of the roof main body 11. A hole is formed through the roof mounting portion 30a to allow the bracket mounting means 31 to pass through. The bracket mounting means 31 that penetrates the roof mounting portion 30a and the underside 11a of the roof main body 11 (the lower plate portion 41 of the roof material 12) is fastened by screwing into a screw plate 31a arranged inside the roof material 12. A screw hole that screws into the bracket mounting means 31 is formed in the screw plate 31a, and a bolt 27 can be inserted into this screw hole for fastening. This screw plate 31a can be, for example, a turn nut that is inserted into the hollow portion of the roof material 12. If a turn nut is used, it can be inserted through a screw hole, making it possible to easily position the screw plate 31a in the hollow portion of the roof material 12. In this embodiment, the roof mounting part 30a can be attached to any position on the roof main body 11 by adjusting the positions of the screw holes and the screw plate 31a.

[0040] The first gutter mounting portion 30b and the second gutter mounting portion 30e are provided on both sides of the roof mounting portion 30a and are fixed to the side walls of the gutter 32. That is, the first gutter mounting portion 30b is fixed to one side wall of the gutter 32 (the vertical wall portion 32a described below), and the second gutter mounting portion 30e is fixed to the other side wall of the gutter 32 (the bent wall portion 32b described below).

[0041] The first gutter mounting portion 30b is formed so as to be vertical when mounted. This first gutter mounting portion 30b bends and extends downward from the end of the roof mounting portion 30a, and is connected to the roof mounting portion 30a so as to form an acute angle with it.

[0042] The second gutter mounting portion 30e is formed so as to be horizontal when mounted. This second gutter mounting portion 30e is provided at the tip of the horizontally extending horizontal extension portion 30d. A hanging portion 30c is provided between the horizontal extension portion 30d and the roof mounting portion 30a. The hanging portion 30c bends and extends downward from the end of the roof mounting portion 30a (the end opposite the end from which the first gutter mounting portion 30b extends) and is connected to the roof mounting portion 30a at an obtuse angle. As the roof mounting portion 30a, the hanging portion 30c, and the horizontal extension portion 30d are bent and connected in this order, a step portion 30f is formed on the upper surface of the gutter bracket 30. The formation of this step portion 30f allows the gutter bracket 30 to be positioned while avoiding the tip member 13 that protrudes downward from the roof main body 11, as shown in FIG. 6. In other words, the gutter bracket 30 and the tip member 13 do not interfere with each other.

[0043] The horizontal gutter 32 is a member for collecting and draining rainwater that has flowed down the upper surface of the roof body 11. In this embodiment, the horizontal gutter 32 is arranged at the end of the roof material 12 in the longitudinal direction D, so it can also collect and drain rainwater that has flowed down the intermediate gutter section 54, secondary gutter section 64, etc. Rainwater collected in the horizontal gutter 32 is discharged to the outside through the vertical gutter 34 that communicates with the horizontal gutter 32. The vertical gutter 34 in this embodiment communicates with a drainage hole formed in the bottom surface section 32f of the horizontal gutter 32.

[0044] The horizontal gutter 32 according to this embodiment is a bent, long plate-like member as shown in Fig. 7. The horizontal gutter 32 according to this embodiment is made of a bent metal plate material. The vertical wall portion 32a and the bent wall portion 32b rise from both ends of the bottom surface portion 32f in the short direction of the horizontal gutter 32, giving the horizontal gutter 32 a generally U-shaped cross section that opens upward.

[0045] The bottom surface portion 32f forms the bottom surface of the gutter shape through which rainwater flows. The bottom surface portion 32f according to this embodiment is positioned horizontally when installed. This bottom surface portion 32f is formed with a drainage hole for draining rainwater. This drainage hole is connected to the upper end of the downspout 34, so that rainwater collected in the horizontal gutter 32 flows from the drainage hole into the downspout 34 and is then drained to the outside through the downspout 34.

[0046] The vertical wall portion 32a is a portion that is disposed vertically in the attached state. This vertical wall portion 32a is placed over the first gutter mounting portion 30b of the gutter bracket 30 described above, and is fixed by gutter mounting means 33. The gutter mounting means 33 in this embodiment is a tapping screw that passes through the vertical wall portion 32a and the first gutter mounting portion 30b.

[0047] 6, the bent wall portion 32b is a portion formed by bending the vicinity of the tip into an L-shape. The bent wall portion 32b includes an upright portion 32c that rises vertically from the bottom surface portion 32f, a horizontal portion 32d that bends at a right angle from the upper end of the upright portion 32c, and a tip portion 32e that extends upward from the end of the horizontal portion 32d.

[0048] Of these, the horizontal portion 32d is the portion that abuts against the second gutter mounting portion 30e of the above-mentioned gutter bracket 30. This horizontal portion 32d is placed over the second gutter mounting portion 30e of the above-mentioned gutter bracket 30 and fixed by gutter mounting means 33. The gutter mounting means 33 in this embodiment is a tapping screw that passes through the horizontal portion 32d and the second gutter mounting portion 30e.

[0049] This gutter 32 can be easily attached to an existing roof body 11. When attaching this gutter 32, first, the gutter bracket 30 is brought into contact with the underside 11a of the roof body 11, and the bracket attachment means 31 is operated from below and screwed in place. The gutter 32 is then attached so as to cover the bracket attachment means 31 from below, and secured in place with the gutter attachment means 33. The gutter attachment means 33 is operated from below or the side and screwed in place, making it easy to work from the underside 11a of the roof body 11.

[0050] The gutter 32 attached to the roof body 11 via the gutter bracket 30 in this way can be easily removed. That is, the gutter 32 is simply fastened with screws to the gutter mounting means 33, so it can be easily removed by unscrewing the screws. Furthermore, the screw fastening operation can be performed from the underside, so the gutter 32 can be removed downward, making the work easier. Furthermore, production costs can be reduced because the horizontal gutter bracket 30 is a short material. Furthermore, the horizontal gutter bracket 30 has a simple shape, making it easy to manufacture.

[0051] As shown in Figure 6, when the horizontal gutter 32 is placed near a wall surface 71, a water-repellent material 35 may be provided on top of the horizontal gutter 32. The water-repellent material 35 is attached to the wall surface 71 and can guide rainwater that runs down the wall surface 71 to the horizontal gutter 32. The water-repellent material 35 according to this embodiment includes an inclined piece 35a that protrudes diagonally downward from the wall surface 71, and a hanging piece 35b that protrudes downward from the tip of the inclined piece 35a. The horizontal gutter 32 is placed on an extension of the hanging piece 35b.

[0052] As described above, according to this embodiment, the horizontal gutter 32 is removably attached, so that when performing maintenance on the gutter such as cleaning, the horizontal gutter 32 can be removed and the work can be performed, making the work easier.

[0053] The roof body 11 is formed by arranging multiple roofing materials 12 in a predetermined direction and joining them together, with adjacent roofing materials 12 joined together by engaging a first joint 50 provided on one of them with a second joint 60 provided on the other, and horizontal gutters 32 are attached to the ends of the roofing materials 12 in the longitudinal direction D. This configuration allows the roof body 11 to be assembled simply by engaging the roofing materials 12, making for excellent workability. Furthermore, because the horizontal gutters 32 are attached to the ends of the roofing materials 12 in the longitudinal direction D, rainwater and the like that flows down from the roofing materials 12 can be caught by the horizontal gutters 32.

[0054] Furthermore, the gutter bracket 30 is attached to the flat underside 11a of the roof body 11. This allows the gutter bracket 30 to be attached anywhere on the flat underside 11a, making it possible to adjust the position of the gutter 32 to suit construction conditions. For example, the gutter 32 can be easily attached to an existing roof body 11.

[0055] Furthermore, the gutter bracket 30 is attached to the underside 11a of the roof main body 11 by the bracket attachment means 31, and the gutter 32 is attached so as to cover the bracket attachment means 31 from below. With this configuration, work can be done from the underside 11a of the roof main body 11, which improves workability. In addition, the bracket attachment means 31 cannot be seen from below, which improves design.

[0056] Furthermore, the gutter 32 is made of bent plate material. This allows for easy and inexpensive production of various shapes of gutter. For example, as shown in FIG. 11(a), a wide gutter 32 may be produced and used. Alternatively, as shown in FIG. 11(b), a gutter 32 with a bent wall portion 32b rising at an angle may be produced and used. In this way, it is possible to produce and use gutter types suited to various construction sites.

[0057] The gutter bracket 30 also includes a roof mounting portion 30a that is attached by abutting against the underside 11a of the roof main body 11, and gutter mounting portions (first gutter mounting portion 30b and second gutter mounting portion 30e) that are provided on both sides of the roof mounting portion 30a and fixed to the side wall portions (vertical wall portion 32a and bent wall portion 32b) of the gutter 32. This allows the gutter bracket 30 to be attached from the underside 11a side of the roof main body 11, improving workability.

[0058] Furthermore, the roof mounting portion 30a is inclined along the slope of the roof, so that the gutter bracket 30 and the gutter 32 can be stably attached to the inclined roof body 11 at the intended angle.

[0059] The gutter bracket 30 also includes a tip member 13 that is attached to the end of the roof main body 11, and the tip member 13 protrudes downward from the roof main body 11, and the gutter bracket 30 includes a step portion 30f to avoid interference with the tip member 13. With this configuration, the gutter bracket 30 can be attached to the underside 11a of the roof main body 11 while avoiding interference with the tip member 13.

[0060] Furthermore, the gutter bracket 30 is positioned inside the gutter shape of the gutter 32. Specifically, the first gutter mounting portion 30b and the second gutter mounting portion 30e are both positioned inside the gutter 32, and the gutter bracket 30 does not protrude outward beyond the outer shape of the gutter 32. With this configuration, rainwater that falls onto the gutter bracket 30 can be received by the gutter 32, preventing the rainwater from scattering.

[0061] The beams 70 may be arranged in a direction perpendicular to the longitudinal direction of the roofing material 12 in a plan view, as shown in Figure 9, or may be arranged in parallel to the longitudinal direction of the roofing material 12 in a plan view, as shown in Figure 10. In this way, common components can be used for construction at various sites, thereby reducing manufacturing costs.

[0062] Furthermore, in the above-described embodiment, the roof body 11 is inclined so that the tip end is higher, but this is not limited to this, and the horizontal gutter 32 of this embodiment may be provided on a roof body 11 inclined so that the tip end is lower. [Explanation of symbols]
