Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the above-mentioned roof structure, when the distance between columns increases, there is a risk that the central part of the roof support will bend downward due to the load of the roof body. When the roof support bends, not only the appearance quality is impaired, but there is also a concern that water such as rainwater will accumulate in the central part. In particular, in a carport, even in a case where a plurality of automobiles are parked side by side, it is difficult to add a column to the middle part of the roof support, and the above-mentioned problem becomes remarkable as the support span becomes longer.

[0005] In view of the above situation, an object of the present invention is to provide a roof structure capable of preventing a situation in which the appearance quality and drainage performance are impaired.

Means for Solving the Problems

[0006] To achieve the above objective, the roof structure according to the present invention is a roof structure comprising a roof support member installed between a column structure including columns, wherein a roof body is supported by the roof support member, and the roof support member is attached to the column structure in an upwardly convex state and is deformed to become substantially flat under the load of the roof body. [Effects of the Invention]

[0007] According to the present invention, since the roof support material is provided so as to be substantially flat when the load of the roof is applied, there is no risk of the central part of the roof support material bending downward due to the load of the roof. This prevents situations in which the appearance quality or drainage performance is impaired. [Brief explanation of the drawing]

[0009] Hereinafter, preferred embodiments of the roof structure according to the present invention will be described in detail with reference to the attached drawings.

[0010] (Embodiment) Figures 1 to 4 show an outdoor structure to which an embodiment of the present invention is applied. The outdoor structure illustrated here is a carport with a rectangular outer shape, intended for installation in a flat parking space, and is composed of a support column structure 1, a plurality of purlins (roof support members) 30, and a roof body 40. The support column structure 1 is composed of left and right front columns 10A, left and right rear columns 10B, and left and right beams 20.

[0011] The front columns 10A and rear columns 10B are extruded profiles formed from a metal such as an aluminum alloy, and are erected vertically on both sides of the parking space, in the front and rear sections, respectively. In this embodiment, the front columns 10A and rear columns 10B have the same cross-sectional shape. The spacing between the front columns 10A is the same as the spacing between the rear columns 10B. The projection dimension from the ground is set so that the rear columns 10B are lower than that of the front columns 10A. The projection dimensions of the two front columns 10A are equal to each other, and the projection dimensions of the two rear columns 10B are equal to each other.

[0012] The beam 20 is an extruded profile formed from a metal such as an aluminum alloy, and is configured to have a symmetrical shape on the left and right sides. In this embodiment, the beam 20 is composed of a beam body 21, a purlin connecting part 22, an outward extension part 23, and an inward extension part 24. The beam body 21 and the purlin connecting part 22 each have a rectangular cylindrical cross-section. The beam body 21 has a horizontally elongated rectangular cross-section, with a width along the left and right sides that is approximately equal to the width along the left and right sides of the front column 10A, and a height dimension that is smaller than the width dimension. The purlin connecting part 22 has a vertically elongated rectangular cross-section, with a width along the left and right sides that is smaller than the width along the left and right sides of the front column 10A, and a height dimension that is larger than the width dimension. In the illustrated example, the purlin connection section 22 is provided on the upper part of the beam body 21 such that the inner surface 22a of the purlin connection section 22 lies on the same plane as the inner surface 21a of the beam body 21. The outward extension section 23 and the inward extension section 24 extend almost horizontally from the lower parts on both sides of the beam body 21 in directions away from each other, and then extend almost vertically upward. The lower surfaces of the outward extension section 23 and the inward extension section 24 are continuous with the lower surface of the beam body 21 and are located on the same plane as the lower surface of the beam body 21. The upward extension dimensions of the outward extension section 23 and the inward extension section 24 are approximately equal to the height dimension of the beam body 21. The outward extension dimension of the outward extension section 23 is approximately equal to the inward extension dimension of the inward extension section 24. The outward extension 23 is provided with a side frame connecting piece 23a on the upwardly extending portion, and the inward extension 24 is provided with a roof connecting piece 24a on the upwardly extending portion. The side frame connecting piece 23a extends almost horizontally inward from the upper edge of the outward extension 23. The roof connecting piece 24a extends almost horizontally inward from the upper edge of the inward extension 24. The dimensions of the beam body 21, outward extension 23, and inward extension 24 along their longitudinal sides are approximately the same as the dimensions along the front and rear of the roof body 40, while the dimensions of the purlin connecting piece 22 along their longitudinal sides are shorter than the dimensions along the front and rear of the roof body 40, and longer than the distance between the front column 10A and the rear column 10B. The rear end of the beam body 21 and the rear end of the purlin connecting piece 22 lie on the same plane. Caps 22b are attached to both the front and rear ends of the main building connection section 22.

[0013] This beam 20 is attached to the portion extending from the upper end of the front column 10A to the upper end of the rear column 10B in a state where the inner surface 21a of the beam main body 21 is on the same plane as the inner surface 10Aa of the front column 10A and the inner surface 10Ba of the rear column 10B. The beam 20 provided between the front column 10A and the rear column 10B is inclined so as to gradually descend rearward, and the front end of the attic connecting portion 22 protrudes forward of the front column 10A, and the rear end of the attic connecting portion 22 protrudes rearward of the rear column 10B.

[0014] The attic 30 is an extruded profile formed of a metal such as an aluminum alloy, and has an attic base portion 31 having a tubular shape with a square cross-section and roof support fin portions 32 extending from the lower edge portion of the attic base portion 31 to both sides. In the illustrated example, when placed on the inner extension portion 24 of the beam 20 via the roof support fin portion 32, the height of the attic 30 is set to be substantially the same as that of the attic connecting portion 22. This attic 30 is substantially orthogonal to the longitudinal direction of the beam 20, and a plurality of them are arranged side by side between the left and right beams 20 with their respective ends placed on the upper surface of the inner extension portion 24. More specifically, attic connecting brackets (connecting tools) 33 are provided at appropriate positions on the attic connecting portion 22. By screwing a screw member 34 into the attic connecting bracket 33 through the attic base portion 31 with the attic connecting bracket 33 inserted into the tubular interior of the attic base portion 31, a plurality of attics 30 are arranged at substantially equal intervals between the beams 20. The attic connecting bracket 33 extends in a direction orthogonal to the inner surface of the attic connecting portion 22. Two screw holes 33a of the attic connecting bracket 33 are arranged side by side along the vertical direction.

[0015] The roof structure 40 is constructed in a panel-like manner by arranging multiple roofing materials 41 side by side, with the longitudinal sides of the roofing materials 41 aligned with the longitudinal sides of the beams 20 and supported on the underside of the purlins 30. Each roofing material 41 is an extruded profile formed from a metal such as an aluminum alloy. The roofing material 41 used in this embodiment has a flat roof base portion 41a with connecting plate portions 41b protruding upward on both sides, and can be connected to each other via the connecting plate portions 41b. The upward projection dimension of the connecting plate portions 41b is approximately equal to the dimension of the portion extending above the inward extension portion 24. This roof structure 40 is supported by the purlins 30 by screwing screw members 41c into the connecting plate portions 41b via roof support fin portions 32 while the connecting plate portions 41b are in contact with the underside of the purlins 30. The roof structure 40 supported by the purlins 30 is inclined to gradually slope downward toward the rear, similar to the beams 20.

[0016] In addition, the roof body 40 has a front frame 43 provided at the front edge portion and side frames 44 provided at both side edge portions respectively. At the rear edge portion of the roof body 40, a gutter frame 50 and a rear frame 45 are provided over the entire length. The front frame 43, side frames 44, gutter frame 50, and rear frame 45 are each extrusion-molded members formed of a metal such as an aluminum alloy. The gutter frame 50 has a bottom plate portion 50a, a front plate portion 50b, and a rear plate portion 50c. The bottom plate portion 50a is in the form of a flat plate extending substantially along a horizontal plane. The front plate portion 50b extends upward from the front edge of the bottom plate portion 50a and then bends toward the rear side. The rear plate portion 50c extends upward from the rear edge of the bottom plate portion 50a and then bends forward. The upward extension dimension of the rear plate portion 50c is set larger than that of the front plate portion 50b. Specifically described, when the front plate portion 50b is brought into contact with the lower surface of the roof body 40, the extension dimension of the rear plate portion 50c is set such that the portion bent forward at the upper end portion of the rear plate portion 50c is located on the extension of the joint plate portion 41b of the roofing material 41. This gutter frame 50 is supported on the roof body 40 and the beam 20 by screwing a screw member 50d in a state where the bent portion of the front plate portion 50b is in contact with the lower surface of the roof body 40 and the lower surface of the beam 20. Although not shown in the figure, drainage portions 50e for draining water are provided at both left and right end portions of the bottom plate portion 50a with respect to the vertical gutter 11 provided on the rear column 10B respectively. End caps 50f are attached to both end portions of the gutter frame 50. The rear frame 45 is attached to the outer surface of the rear plate portion 50c.

[0017] In the roof body 40 supported on the support structure 1 via the main house 30 as described above, the water received during rainfall or the like travels sequentially backward along the roof base plate portion 41a of each roofing material 41. The water that has passed through the rear edge of the roof body 40 is received by the gutter frame 50 and then discharged to the vertical gutter 11 through the drainage portions 50e at both end portions. Therefore, it is possible to prevent a situation where water such as rainwater reaches the parking space covered by the roof body 40.

[0018] Here, the purlins 30 that support the roof structure 40 are connected to the beams 20 only at both ends. If these purlins, which extend in a straight line, are simply erected between the support structures 1, there is a risk that the load from supporting the roof structure 40 will cause the central part to bend downwards. If the purlins 30 bend, it will result in a loss of aesthetic quality. Furthermore, as the roof structure 40 deforms along with the bending of the purlins 30, there is a concern that rainwater or other water may accumulate in the central part of the gutter frame 50.

[0019] Therefore, in the carport of this embodiment, as shown in Figure 5, a purlin 30 that has been formed in advance so that its central portion is curved to one side is applied and installed between the support column structures 1 in an upwardly convex position. The curved shape of the purlin 30 is set so that when the roof body 40 is supported it flexes to become approximately flat or slightly convex upward. In other words, the curved shape of the purlin 30 is set so that the amount of deflection of the purlin 30 in relation to the load of the roof body 40 that it supports is calculated in advance and this amount of deflection is set to be almost zero or a small amount of deflection remains when the roof body 40 is supported. With a carport using the roof structure of this embodiment, since the purlin 30 is formed so that it becomes approximately flat when the load of the roof body 40 is applied, there is no risk of the central portion of the purlin 30 flexing downward due to the load of the roof body 40. This makes it possible to prevent situations in which the appearance quality or drainage performance is impaired.

[0020] In the above-described embodiment, a purlin 30 that is pre-formed to be curved is used, but the present invention is not necessarily limited thereto, and it is also possible to use a purlin 30 that extends in a straight line, as shown in the following modified example.

[0021] (Variation 1) Figure 6 shows an outdoor structure to which the roof structure of Modification 1 is applied. The outdoor structure illustrated here is a carport similar to the embodiment, differing only in the configuration of the purlins. That is, in the carport of Modification 1, each purlin 30 is composed of two purlin components (support components) 30a and a connecting member 30b that connects the purlin components 30a to each other. The purlin components 30a are extruded profiles formed from a metal such as an aluminum alloy, similar to the embodiment, and are composed of a purlin base 31 and a roof support fin 32. The length of the purlin component 30a is set to be slightly larger than half the distance between the purlin connecting parts 22. The connecting member 30b is fixed to each purlin component 30a by inserting both ends into the purlin base 31 of the purlin component 30a and screwing a screw member 30c through the respective purlin base 31. As is clear from Figure 7, the connecting member 30b is bent in the center so that when the purlin members 30a are connected to each end, the purlin members 30a extend in a bent manner relative to each other. Each end of the connecting member 30b is provided with four screw holes 30d for screwing in the screw members 30c. In Modification 1, components similar to those in the embodiment are denoted by the same reference numerals.

[0022] The purlin 30, configured as described above, is installed between the support columns 1 in an upwardly convex position. The bending shape of the purlin 30 is determined by pre-calculating the amount of deflection of the purlin 30 under the load of the roof body 40 it supports, and setting this deflection amount to be almost zero or slightly deflected when the roof body 40 is supported. In a carport using this modified example 1 roof structure, the purlin 30 is formed so that it becomes almost flat when the load of the roof body 40 is applied, thus eliminating the risk of the central part of the purlin 30 deflecting downward due to the load of the roof body 40. This prevents situations where the appearance quality or drainage performance is compromised.

[0023] (Modification 2) Figure 8 shows an outdoor structure to which the roof structure of Modification 2 is applied. The outdoor structure illustrated here is a carport similar to the embodiment, differing only in the configuration of the purlins. That is, in the carport of Modification 2, each purlin 30 is composed of a central purlin component (support structure member) 130a, two lateral purlin components (support structure members) 130b, and two connecting members 130c that connect the central purlin component 130a and the lateral purlin components 130b. The central purlin component 130a and the lateral purlin components 130b are extruded profiles formed from metal such as aluminum alloy, similar to the embodiment, and are composed of a purlin base 31 and a roof support fin 32. The length of the central purlin component 130a is larger than the length of the lateral purlin component 130b, and the length of the two lateral purlin components 130b are equal to each other. The combined length of the central purlin component 130a and the two lateral purlin components 130b is set to be slightly larger than the spacing between the purlin connecting portions 22. The connecting member 130c is fixed to the central purlin component 130a and the lateral purlin components 130b by inserting one end into the purlin base 31 of the central purlin component 130a and the other end into the purlin base 31 of the lateral purlin component 130b, and then screwing in the screw member 130d through each purlin base 31. Similar to the connecting member 30b in Modified Example 1, the central portion of the connecting member 130c is bent so that when the central purlin component 130a and the lateral purlin components 130b are connected to each other, the central purlin component 130a and the lateral purlin components 130b extend in a bent manner relative to each other. The two connecting members 130c are configured to have the same shape as each other. In the modified example 2, the same reference numerals are used for components that are the same as in the embodiment.

[0024] The purlin 30, configured as described above, is installed between the support columns 1 in an upwardly convex position. The bending shape of the purlin 30 is determined by pre-calculating the amount of deflection of the purlin 30 under the load of the roof body 40 it supports, and setting this deflection to be approximately zero when the roof body 40 is supported. In a carport using this modified roof structure 2, the purlin 30 is formed so that it becomes almost flat when the load of the roof body 40 is applied, thus eliminating the risk of the central part of the purlin 30 deflecting downward due to the load of the roof body 40. This prevents situations where the appearance quality or drainage is impaired.

[0025] (Variation 3) Figures 9 and 10 show an outdoor structure to which the roof structure of Modification 3 is applied. The outdoor structure illustrated here is a carport similar to the embodiment, differing only in the configuration of the purlins and one of the purlin connecting brackets. That is, the carport of Modification 3 uses purlins 30 that extend in a straight line. The purlins 30 are extruded profiles formed from a metal such as an aluminum alloy, and are configured to have a purlin base 31 and a roof support fin 32, similar to the embodiment. The purlin connecting brackets (connectors) 33, 133 are attached to the purlin connecting section 22, similar to the embodiment, and the purlins 30 are connected to the beam 20 by screwing screw members 34, 134 into the purlin connecting brackets 33, 133 via the purlin base 31 while the purlins are inserted inside the cylinder of the purlin base 31. The purlin connecting bracket 33 provided at one end of the purlin 30 has the same shape as in the embodiment. In contrast, in the purlin connecting bracket (hereinafter referred to as the curved connecting bracket 133 when distinguishing between them) provided at the other end of the purlin 30, the distance from the purlin connecting portion 22 to the lower screw hole 133a is set to be greater than the distance from the purlin connecting portion 22 to the upper screw hole 133b.

[0026] In this modified example 3, when the purlin 30 is connected to the beam 20 via the bending connecting bracket 133, as described above, the positions of the screw holes 133a and 133b are different, so as shown by the dashed line in the figure, it becomes inclined so as to gradually bend upward toward the other beam 20. If the end of the purlin 30 is connected to the other beam 20 via the purlin connecting bracket 133 from this state, that is, if the purlin 30 is bent while being connected to the other beam 20, the purlin 30 will be curved so as to be convex upward toward the other beam 20, as shown by the solid line in the figure. The curved shape of the purlin 30 is set so that when the roof body 40 is supported it bends, it becomes approximately flat or slightly convex upward toward the other beam 20.

[0027] In a carport using the roof structure of this modified example 3, the purlins 30 are formed so that they are nearly flat when the load of the roof body 40 is applied, thus eliminating the risk of the central part of the purlins 30 sagging downward due to the load of the roof body 40. This prevents situations where the appearance quality or drainage is compromised.

[0028] (Modification 4) Figures 11 and 12 show an outdoor structure to which the roof structure of Modification 4 is applied. The outdoor structure illustrated here is a carport similar to the embodiment, differing only in the configuration of the purlins and one of the purlin connecting brackets. That is, the carport of Modification 4 uses purlins 30 that extend in a straight line. The purlins 30 are extruded profiles formed from a metal such as aluminum alloy, and are configured to have a purlin base 31 and a roof support fin 32, similar to the embodiment. The purlin connecting brackets (connectors) 33, 233 are attached to the purlin connecting section 22, similar to the embodiment, and the purlins 30 are connected to the beam 20 by screwing screw members 34, 234 into the purlin connecting brackets 33, 133 via the purlin base 31 while the purlins are inserted inside the cylinder of the purlin base 31. The purlin connecting bracket 33 provided at one end of the purlin 30 has the same shape as in the embodiment. In contrast, the purlin connecting bracket (hereinafter referred to as the curved connecting bracket 233 when distinguishing between them) provided at the other end of the purlin 30 extends inclined from the inner side of the purlin connecting portion 22, gradually moving upward. As a result, similar to the modified example 3, the distance from the purlin connecting portion 22 to the lower screw hole 233a is greater than the distance from the purlin connecting portion 22 to the upper screw hole 233b.

[0029] In this modified example 4, when the purlin 30 is connected to the beam 20 via the bending connecting bracket 233, as described above, the positions of the screw holes 233a and 233b are different, so as shown by the dashed line in the figure, it becomes inclined so as to gradually bend upward toward the other beam 20. If the end of the purlin 30 is connected to the other beam 20 via the purlin connecting bracket 233 from this state, that is, if the purlin 30 is bent while being connected to the other beam 20, the purlin 30 will be curved so as to be convex upward toward the other beam 20, as shown by the solid line in the figure. The curved shape of the purlin 30 is set so that when the roof body 40 is supported it bends, it becomes approximately flat or slightly convex upward toward the other beam 20.

[0030] In a carport using the roof structure of this modified example 4, the purlins 30 are formed so that they are nearly flat when the load of the roof body 40 is applied, thus eliminating the risk of the central part of the purlins 30 sagging downward due to the load of the roof body 40. This prevents situations where the appearance quality or drainage is compromised.

[0031] In the above-described embodiment, a roof structure applicable to a carport is illustrated, but it can also be applied to the roof structure of other outdoor structures such as terraces. Furthermore, although the left and right front columns 10A are shown as being the same height and the left and right rear columns 10B are set at the same height, the heights of the left and right columns may be different. In addition, although the roof body 40 is shown being supported on the lower surface of the roof support material, the roof body 40 may also be supported on the upper surface of the roof support material. Furthermore, although the support structure 1 is shown as comprising columns and beams 20, the support structure 1 may consist only of columns. That is, the roof material 41 may be supported by beams 20 supported by columns. The beams 20 do not necessarily have to have multiple hollow sections. Also, the roof body 40 does not necessarily have to be constructed by arranging multiple roof materials 41 side by side.

[0032] As described above, the roof structure according to the present invention is a roof structure comprising a roof support member installed between a column structure including columns, wherein the roof body is supported by the roof support member, and the roof support member is attached to the column structure in an upwardly convex state and is deformed to become substantially flat under the load of the roof body. According to this invention, the roof support material is provided so that it becomes substantially flat when the load of the roof is applied, thus eliminating the risk of the central part of the roof support material bending downward due to the load of the roof. This prevents situations where the appearance quality or drainage performance is impaired.

[0033] Furthermore, the present invention is characterized in that, in the roof structure described above, the roof support member is formed so that its central portion is curved to one side and is attached to the support column structure in an upwardly convex position. According to this invention, a single pre-curved roof support member can be used, preventing an increase in the number of parts and thus eliminating the risk of complicating the process of attaching the roof support member to the support structure.

[0034] Furthermore, the present invention is characterized in that, in the roof structure described above, the roof support member comprises a first support component attached so as to be inclined upward from one side of the support column structure, and a second support component attached so as to be inclined upward from the other side of the support column structure, with its extended end connected to the first support component. According to this invention, there is no need to bend the roof support material, and therefore no equipment or processes are required for that purpose.

[0035] Furthermore, the present invention is characterized in that, in the roof structure described above, the roof support member comprises a first support component attached so as to be inclined upward from one side of the support column structure, a second support component attached so as to be inclined upward from the other side of the support column structure, and a third support component connecting the first support component and the second support component. According to this invention, there is no need to bend the roof support material, and therefore no equipment or processes are required for that purpose.

[0036] Furthermore, the present invention is characterized in that, in the roof structure described above, a connecting member is interposed between the support column structure and the roof support member, at least one of the connecting members connects the support column structure and the roof support member in an inclined position upward, and the roof support member becomes curved when connected to the other connecting member. According to this invention, there is no need to bend the roof support material, eliminating the need for equipment and processes for that purpose. Furthermore, a single roof support material can be used, preventing an increase in the number of parts and thus avoiding the possibility of complicating the work of attaching the roof support material to the support structure.

[0037] Furthermore, the present invention is characterized in that, in the roof structure described above, the roof body is provided with a rain gutter frame at the edge along the longitudinal side of the roof support material. This invention makes it possible to prevent water, such as rainwater, from accumulating in the gutter frame. [Explanation of symbols]
