Summary of the Invention

Problem to be Solved by the Invention

[0004] By the way, in order to space the roof panels upward relative to the beams in the above-described outdoor structure, upper beams and strut members are required. That is, in this outdoor structure, upper beams are provided so as to span over the plurality of roof panels arranged side by side, and further strut members are provided between the upper beams and the beams, so that the roof structure is supported by the beams. For this reason, the number of parts to be handled increases, and for example, there is still room for improvement in consideration of workability during assembly.

[0005] In view of the above circumstances, the present invention aims to provide an outdoor structure that can achieve improved appearance quality without impairing workability during assembly. [Means for solving the problem]

[0006] To achieve the above objective, the outdoor structure according to the present invention comprises a support structure composed of columns and beams, and a roof structure in which a plurality of roofing materials are arranged side by side along the longitudinal side of the front frame between a front frame and a rear frame, wherein the roofing materials are The substrate portion and the first connecting plate portion and the second connecting plate portion that protrude upward from both sides of the substrate portion are integrally molded, and the substrate portion The lower surface is positioned above the lower surface of the front frame and the lower surface of the rear frame, and the extending direction of the front frame intersects the extending direction of the beam, with the lower surface of the front frame and the lower surface of the rear frame only The roof structure is characterized by being supported by the support structure via [a certain mechanism]. [Effects of the Invention]

[0007] According to the present invention, the roofing material is installed so that its lower surface is positioned above the front and rear frames, and the front and rear frames on which the roofing material is installed are directly supported by the support structure. As a result, a space can be secured between the roofing material and the beams without requiring upper beams or support members, which not only improves the aesthetic appeal but also allows for lighting effects without exposing lighting fixtures to the outside, thereby improving the overall appearance.

[Modes for carrying out the invention]

[0009] Hereinafter, preferred embodiments of the outdoor structure according to the present invention will be described in detail with reference to the attached drawings. Figures 1 to 4 show an outdoor structure that is an embodiment of the present invention. The outdoor structure illustrated here is used as a carport installed in a parking space PS and is composed of a support structure 10 and a roof structure 20.

[0010] The support structure 10 is for supporting the roof structure 20, which will be described later, and comprises a support column 11 and a beam 12 provided on the upper part of the support column 11. In this embodiment, the support structure 10 is constructed by arranging two support columns 11 side by side on one side of the parking space PS, and by extending the beam 12 inclined upward from the upper part of each support column 11 in the same direction.

[0011] As shown in Figure 5(a), the support column 11 is an extruded profile integrally formed from a column base 11a with a roughly rectangular cross-section and two outward fin portions 11b extending in the same direction from the two corners of the column base 11a, and is formed from a metal such as aluminum alloy. As shown in Figures 1 to 4, each support column 11 is erected from the ground G so that they are at approximately the same height with their outward fin portions 11b facing outwards from the parking space PS. A support column cover 13 is attached to the portion between the two outward fin portions 11b that is above the ground G.

[0012] As shown in Figure 5(b), the beam 12 is an extruded profile integrally formed from a beam base 12a, which has a roughly rectangular cross-section, and beam trough components 12b provided at the two corners of the beam base 12a. It is formed from a metal such as aluminum alloy. The beam trough components 12b extend in the left-right direction from the two lower corners of the beam base 12a in directions away from each other, and then bend upward to form a beam trough 12c between it and the beam base 12a. This beam 12 is configured to be narrower in width than the support column 11.

[0013] A connecting bracket 14 is used at the connection point between the column 11 and the beam 12. As shown in Figure 6, the connecting bracket 14 has a column insertion portion 14a that is inserted into the cylinder of the column base 11a in the column 11, and a beam insertion portion 14b that is inserted into the cylinder of the beam base 12a in the beam 12, with the beam insertion portion 14b extending from one end of the column insertion portion 14a in a direction that intersects it. The connecting bracket 14 is connected to the column 11 and the beam 12 by inserting the column insertion portion 14a into the cylinder of the column base 11a and the beam insertion portion 14b into the cylinder of the beam base 12a, and screwing connecting bolts (connecting members) 15 between the column 11 and the connecting bracket 14 and between the beam 12 and the connecting bracket 14, respectively. As is clear from the diagram, between the connecting bracket 14 and the support column 11, the connecting bolts 15 are screwed into the connecting bracket 14 via the column base 11a between the outer fin portions 11b. Therefore, when the carport is in use, the connecting bolts 15 are covered by the support column cover 13, which is advantageous in terms of appearance quality. Also, between the connecting bracket 14 and the beam 12, the connecting bolts 15 are screwed into the connecting bracket 14 via the upper surface of the beam 12. When the carport is in use, the upper surface of the beam 12 is at a high position, making it difficult to see the connecting bolts 15, which is advantageous in terms of appearance quality.

[0014] As shown in Figures 1 to 4, the roof structure 20 comprises a frame 120 and a plurality of roofing materials 220 and auxiliary roofing materials 230 provided inside the frame 120. The frame 120 is constructed in a rectangular shape by arranging a front frame 122 and a rear frame 123 between the ends of two side frames 121 that are arranged to be substantially parallel to each other. These side frames 121, front frame 122, and rear frame 123 are extruded profiles formed from metal such as aluminum alloy, and are configured to have a substantially uniform cross-sectional shape along their entire length.

[0015] As shown in Figure 7(a) and Figure 7(b), the two side frames 121 have cross-sectional shapes that are symmetrical to each other, and a side frame base plate portion 121a, a side frame upper fin portion 121b, a side frame lower fin portion 121c, a drain gutter constituting portion 121d, a roof material connecting portion 121e, and a side frame cover portion 121f are integrally molded. The side frame base plate portion 121a has a flat plate shape extending along the vertical direction. The side frame upper fin portion 121b is provided so as to protrude to the outer peripheral side from the upper part of the surface on the outer peripheral side of the side frame base plate portion 121a, and is configured in a substantially rectangular tubular cross-section. The side frame lower fin portion 121c is provided so as to protrude to the outer peripheral side from the lower end portion of the surface on the outer peripheral side of the side frame base plate portion 121a, and is configured in a substantially rectangular tubular cross-section. The projection dimension of the side frame lower fin portion 121c from the side frame base plate portion 121a is set to be smaller than that of the side frame upper fin portion 121b. The drain gutter constituting portion 121d extends in the left-right direction from the lower end edge of the side frame base plate portion 121a toward the inner peripheral side, and then bends upward, thereby forming a drain gutter portion 121g between itself and the side frame base plate portion 121a. The roof material connecting portion 121e extends in the left-right direction from the upper end edge of the side frame base plate portion 121a toward the inner peripheral side. The side frame cover portion 121f has a plate shape provided so as to protrude to the inner peripheral side from the upper part of the surface on the inner peripheral side of the side frame base plate portion 121a. The protruding edge of the side frame cover portion 121f is bent upward. A gap capable of accommodating a roof material 220 and an auxiliary roof material 230 (hereinafter sometimes simply referred to as the roof material or the like 220, 230) described later is secured between the side frame cover portion 121f and the roof material connecting portion 121e.

[0016] As shown in Figure 7(c), the front frame 122 is integrally molded with a front roof material support portion 122a, a roof end opposing portion 122b, a front frame water receiving gutter component portion 122c, a front frame upper fin connecting portion 122d, and a front frame lower fin portion 122e. The front roof material support portion 122a has a cylindrical shape with a roughly rectangular cross-section. A front frame contact portion 122f is provided at the upper corner located on the inner circumference side of the front roof material support portion 122a. The front frame contact portion 122f protrudes above the upper surface of the front roof material support portion 122a and has an upward-facing front contact surface 122g, and a watertight material 122h is provided on the portion on the inner circumference side of the front contact surface 122g. The portion of the upper surface of the front roof material support portion 122a that is on the outer periphery side of the front frame contact portion 122f is configured to be lower than the front frame contact portion 122f in order to secure a space 122i for waterproofing the front frame between it and the lower surfaces 220a1, 230a1 of the roof materials, etc., described later. The roof end opposing portion 122b has a cylindrical shape with a roughly rectangular cross-section and is provided so as to protrude upward from the outer edge on the upper surface of the front roof material support portion 122a. A screw groove portion 122j is provided at the upper corner located on the inner periphery side of the roof end opposing portion 122b. The screw groove portion 122j is a groove-shaped recess that opens upward. The front frame water receiving gutter component 122c extends horizontally inward from the lower corner located on the inner circumference side of the front roof material support portion 122a, and then bends upward to form the front frame water receiving gutter portion 122k between it and the front roof material support portion 122a. The front frame upper fin connecting portion 122d consists of two protrusions for attaching the upper fin member 124, which has a rectangular cross-section and is cylindrical in shape, and protrudes outward from the outer surface of the roof end opposing portion 122b. The front frame lower fin portion 122e is provided so as to protrude outward from the lower end surface on the outer circumference side of the front roof material support portion 122a, and has a roughly rectangular cross-section and is cylindrical in shape. The protrusion dimension of the front frame lower fin portion 122e is approximately the same as that of the side frame lower fin portion 121c provided on the side frame 121.

[0017] As shown in Fig.7(d), the rear frame 123 supports later-described roof materials 220, 230 and the like between itself and the front frame 122, and a rear roof material support portion 123a, a rear frame water-receiving gutter constituting portion 123b, a lateral gutter constituting portion 123c, a rear frame upper fin connecting portion 123d, and a rear frame lower fin portion 123e are integrally formed. The rear roof material support portion 123a has a substantially quadrangular cylindrical cross-section, and has a rear frame abutting portion 123f at an upper corner located on the inner peripheral side. The rear frame abutting portion 123f protrudes upward from the upper surface of the rear roof material support portion 123a, has an upward-facing rear abutting surface 123g, and is provided with a watertight member 123h at a portion located on the inner peripheral side relative to the rear abutting surface 123g. On the upper surface of the rear roof material support portion 123a, the portion located on the outer peripheral side relative to the rear frame abutting portion 123f is configured to be one step lower than the rear frame abutting portion 123f so as to secure a rear frame water stop space 123i between itself and the lower surfaces 220a1, 230a1 of the later-described roof materials 220, 230 and the like. The rear frame water-receiving gutter constituting portion 123b extends in the left-right direction from the lower corner located on the inner peripheral side of the rear roof material support portion 123a toward the inner peripheral side, and then bends upward to form a rear frame water-receiving gutter portion 123j between itself and the rear roof material support portion 123a. The lateral gutter constituting portion 123c extends in the left-right direction from the lower end edge of the outer peripheral side surface of the rear roof material support portion 123a toward the outer peripheral side, then bends and extends upward to form a lateral gutter portion 123k between itself and the rear roof material support portion 123a. The extending edge of the lateral gutter constituting portion 123c protrudes upward beyond the rear frame abutting portion 123f, and has substantially the same height as the upper surface of the roof end opposing portion 122b provided on the front frame 122. The rear frame upper fin connecting portions 123d are two protruding portions for mounting the upper fin member 124, and protrude toward the outer peripheral side from the outer peripheral side surface of the vertically extending portion of the lateral gutter constituting portion 123c. The rear frame lower fin portion 123e is provided so as to protrude toward the outer peripheral side from the outer peripheral side lower end surface of the vertically extending portion of the lateral gutter constituting portion 123c, and is configured in a substantially rectangular cylindrical shape in cross section. The projection dimension of the rear frame lower fin portion 123e is substantially the same as that of the side frame lower fin portion 121c provided on the side frame 121.

[0018] As shown in Figures 8 and 9, the side frame 121, front frame 122, and rear frame 123, having the above configuration, have notches 125 formed in advance at both ends of the portion of the side frame 121 that extends above the drainage gutter component 121d and at both ends of the side frame cover portion 121f, respectively. The ends of the front frame 122 and the rear frame 123 are assembled around the four sides in close proximity to the inner surface of the side frame base portion 121a, thereby forming the frame 120 of the roof structure 20. Reference numeral 126 in the figures indicates a corner cap provided at the outer corner between the side frame 121 and the front frame 122 and rear frame 123.

[0019] As shown in Figures 1, 4, and 10, the roofing material 220 and the auxiliary roofing material 230 are arranged side by side to cover the inside of the frame 120. In this embodiment, the roofing material 220 and the auxiliary roofing material 230 are made of extruded profiles formed from a metal such as an aluminum alloy.

[0020] As shown in Figure 10(b), the roofing material 220 is integrally molded from a base plate portion 220a, a first connecting plate portion 220b, and a second connecting plate portion 220c, and has a length that can be spanned between the front frame 122 and the rear frame 123. The base plate portion 220a is flat. The first connecting plate portion 220b extends upward almost vertically from one edge of the base plate portion 220a. The second connecting plate portion 220c extends inclined upward outward from the other edge of the base plate portion 220a, and then extends upward almost vertically. The height dimensions of the first connecting plate portion 220b and the second connecting plate portion 220c are set to be smaller than the gap between the side frame cover portion 121f and the roofing material connecting portion 121e provided on the side frame 121. The first connecting plate portion 220b is provided with a groove component 220d and a water receiving component 220e on its outer surface, and the second connecting plate portion 220c is provided with a groove cover portion 220f and a water receiving cover portion 220g on its outer surface.

[0021] The groove component 220d extends outward from the upper part of the first connecting plate portion 220b in a left-right direction, and then extends upward almost vertically, thereby forming a groove portion 220h between it and the first connecting plate portion 220b. The groove portion 220h is a recess that opens upward and is formed along the entire length of the longitudinal side of the first connecting plate portion 220b.

[0022] The water receiving component 220e extends inclined upward outward from the lower edge of the first connecting plate 220b, then extends outward in the left-right direction, and further extends upward almost vertically, thereby forming a water receiving portion 220i between it and the first connecting plate 220b. The water receiving portion 220i is a wide recess that opens upward and protrudes outward from the groove 220h, and is formed along the entire length of the longitudinal side of the first connecting plate 220b. The protrusion dimension of the water receiving component 220e from the first connecting plate 220b is set to be shorter than the protrusion dimension of the roof material connecting portion 121e from the side frame base plate 121a in the side frame 121. The inclined angle and height dimension of the portion of the water receiving component 220e that extends inclined are approximately the same as those of the portion of the second connecting plate 220c that extends inclined. In other words, when two roofing materials 220 are installed side by side such that the first connecting plate portion 220b and the second connecting plate portion 220c face each other, the second connecting plate portion 220c and the water receiving component portion 220e are configured such that a roughly isosceles trapezoidal recess 220j is formed between their lower portions.

[0023] The groove cover portion 220f extends outward from the upper edge of the second connecting plate portion 220c in a left-right direction. A drainage portion 220k is provided on the extended edge of the groove cover portion 220f so as to extend downward. The lower edge of the drainage portion 220k is inclined downward toward the outside. The height dimension of the lower surface of the groove cover portion 220f is set to be approximately the same as the height dimension to the upper edge of the first connecting plate portion 220b. The protrusion dimension of the groove cover portion 220f from the second connecting plate portion 220c is set to be larger than the protrusion dimension of the water receiving component portion 220e from the first connecting plate portion 220b.

[0024] The water receiving cover portion 220g extends outward in the left-right direction from approximately the middle of the second connecting plate portion 220c, and then extends downward, thereby forming an insertion groove 220m between it and the second connecting plate portion 220c. The lower edge of the water receiving cover portion 220g is inclined downward toward the outside. The width of the insertion groove 220m is set to a dimension that allows the vertical portion of the water receiving component 220e to be inserted. The height of the inner bottom surface of the insertion groove 220m is set to be approximately the same as the height dimension to the upper edge of the water receiving component 220e.

[0025] As shown in Figure 10(c), the auxiliary roofing material 230 is formed by integrally molding an auxiliary base plate portion 230a and two auxiliary first connecting plate portions 230b, and has approximately the same length as the roofing material 220. The auxiliary base plate portion 230a is flat, similar to the base plate portion 220a of the roofing material 220. The two auxiliary first connecting plate portions 230b extend upward from both sides of the auxiliary base plate portion 230a, approximately vertically. The height dimension of the auxiliary first connecting plate portions 230b is approximately the same as that of the first connecting plate portion 220b of the roofing material 220. The two auxiliary first connecting plate portions 230b are provided with groove components 230c and water receiving components 230d on their respective outer surfaces. The groove component 230c and the water receiving component 230d are the same as those provided on the roofing material 220, and the auxiliary roofing material 230 has a groove portion 220h and a water receiving portion 220i.

[0026] The roofing material 220 and auxiliary roofing material 230 configured as described above are fixed to the frame 120 in the following manner, thereby constituting the roof structure 20. Specifically, the roofing material 220 is arranged with the first connecting plate portion 220b and the second connecting plate portion 220c facing each other, the water receiving component 220e is inserted into the insertion groove 220m, and the groove portion 220h is covered by the groove cover portion 220f. At this time, since the water receiving cover portion 220g is provided on the same second connecting plate portion 220c as the groove cover portion 220f, when covering the groove portion 220h provided on the first connecting plate portion 220b with the groove cover portion 220f, it is possible to simultaneously cover the water receiving component 220e provided on the first connecting plate portion 220b with the water receiving cover portion 220g, making it possible to easily perform the work of arranging the roofing materials 220 side by side.

[0027] From this state, by screwing a screw 240 into the groove portion 220h via the groove cover portion 220f, multiple roofing materials 220 can be connected to each other while being arranged side by side. The roofing material 220 and the front frame 122 can be fixed together by screwing a screw 241 into the front contact surface 122g of the front roofing material support portion 122a via the base plate portion 220a. It is preferable to pre-install an end watertight material 122m on the inner surface of the roof end opposing portion 122b, and to bring the end of the roofing material 220 into contact with this end watertight material 122m without any gaps. Similarly, the roofing material 220 and the rear frame 123 can be fixed together by screwing a screw 242 into the rear contact surface 123g of the rear roofing material support portion 123a via the base plate portion 220a. The first connecting plate portion 220b of the roofing material 220 and the side frame 121 can be fixed together by placing the first connecting plate portion 220b between the side frame cover portion 121f of the side frame 121 and the roofing material connecting portion 121e, and screwing a screw 243 into the groove portion 220h via the roofing material connecting portion 121e. The second connecting plate portion 220c of the roofing material 220 and the side frame 121 can be fixed together by interposing an auxiliary roofing material 230, and screwing a screw 244 into the groove portion 220h of the auxiliary roofing material 230 via the roofing material connecting portion 121e of the side frame 121.

[0028] After fixing the roofing material 220 and auxiliary roofing material 230 to the frame 120, a front frame cover 250 is provided on the upper part of the roof end facing portion 122b, while a roofing material cover 260 is provided between the roofing material 220 and auxiliary roofing material 230 and the rear frame 123. The front frame cover 250 is provided so as to cover the end of the roofing material 220 from the upper surface of the roof end facing portion 122b by screwing a screw 245 into the screwing groove portion 122j of the roof end facing portion 122b. The roofing material cover 260 extends from the upper part of the roofing material 220 toward the rear frame 123, and then extends downward at the gutter portion 123k, and is attached to the roofing material 220 by screwing a screw 246 into the groove portion 220h of the roofing material 220.

[0029] The roof structure 20 is positioned on top of the support structure 10 with the side frame 121 aligned with the direction of extension of the beam 12 and the rear frame 123 facing the support column 11. The roof structure 20 is attached to the top of the support structure 10 by screwing screw members 247 onto the beam 12 and support column 11 via the front frame 122 and rear frame 123 of the frame body 120. A drain member 270 is provided in the horizontal gutter section 123k on the rear frame 123, in the portion corresponding to one of the support columns 11. The drain member 270 is for draining water stored in the horizontal gutter section 123k downwards, and its lower end is connected to a downpipe 280 provided on the support column 11. Although not explicitly shown in the figure, the downpipe 280 extends vertically along the portion of the support column 11 between the outer fin section 11b and the support column cover 13. As a result, the water stored in the horizontal gutter section 123k is discharged to the ground G via the drain member 270 and the vertical gutter 280.

[0030] In the roof structure 20 described above, the lower surfaces 220a1 and 230a1 of the roofing materials 220 and 230 are positioned above the lower surface 122a1 of the front frame 122 and the lower surface 123a1 of the rear frame 123. In other words, the base plates 220a and auxiliary base plates 230, which form the lower surfaces of the roofing material 220 and auxiliary roofing material 230, are in contact with the front roofing material support portion 122a provided on the front frame 122 and the rear roofing material support portion 123a provided on the rear frame 123, and are positioned above the upper surface of the support structure 10 to which the lower surface 122a1 of the front frame 122 and the lower surface 123a1 of the rear frame 123 abut. Therefore, with this roof structure 20, it is possible to secure space between the roof materials 220, 230 and the beam 12 without requiring other parts such as upper beams that span multiple roof materials 220 or support members interposed between the beams 12 and the upper beams, thereby improving the aesthetic appearance without complicating the assembly process. Moreover, if lighting fixtures (not shown) are placed in the space between the roof materials 220, 230 and the beam 12, it becomes possible to illuminate the undersides 220a1, 230a1 of the roof materials 220, 230 without the lighting fixtures being visible from the outside, thereby improving the appearance quality.

[0031] Furthermore, according to the roof structure 20 described above, grooves 220h are provided in the first connecting plate portion 220b of the roofing material 220 and the auxiliary first connecting plate portion 230b of the auxiliary roofing material 230, and screws 240 and 244 provided via the groove cover portion 220f of the second connecting plate portion 220c are screwed into these grooves 220h. Moreover, a water drainage portion 220k is provided on the edge of the groove cover portion 220f. Therefore, even without using special screws 240 and 244 with waterproofing material, or without providing a dedicated watertight material between the groove cover portion 220f and the groove component portion 220d, there is no risk of water leakage from between the roofing materials 220 and 230 to the parking space PS. In other words, water that seeps below the groove cover portion 220f through the holes into which the screws 240 and 244 are threaded, and water that seeps below the groove cover portion 220f through the gaps between the groove components 220d and 230c, will all be caught and stored by the groove portion 220h, so there is no risk of it dripping onto the parking space PS. Moreover, even if the water in the groove portion 220h overflows, the overflowing water will be caught by the water receiving portion 220i provided below it, so there is no concern that it will cause problems such as dripping onto the parking space PS. Incidentally, the water caught in the groove portion 220h and water receiving portion 220i of the roofing material 220 and 230 will proceed toward the rear frame 123, be discharged into the horizontal gutter portion 123k of the rear frame 123, and then discharged to the ground G via the drain member 270 and the downpipe 280.

[0032] Furthermore, according to the roof structure 20 described above, the rear contact surface 123g that abuts against the roofing materials 220, 230 in the rear frame 123 is provided on the inner circumference side of the rear roofing material support part 123a, and the end side of the roofing materials 220, 230 is lowered by one step, forming a non-contact rear frame water-stopping space 123i with respect to the roofing materials 220, 230. Therefore, even if water that has advanced toward the rear frame 123 wraps around the ends of the roofing materials 220, 230 and proceeds along the lower surfaces 220a1, 230a1 of the roofing materials 220, 230 toward the front frame 122, it can be dripped off along the way, preventing it from progressing toward the inner circumference side. Even if water were to penetrate beyond the rear frame watertight space 123i and proceed inward, the watertight material 123h is provided between the lower surfaces 220a1 and 230a1 of the roofing materials 220 and 230, thus preventing further inward movement. Furthermore, according to the roof structure 20 described above, the rear frame water receiving gutter 123j is provided in the portion on the inward side below the rear roofing material support portion 123a. Therefore, even if water reaches the inward side beyond the watertight material 123h, it will be caught by the rear frame water receiving gutter 123j, eliminating the risk of water leakage.

[0033] On the other hand, between the front frame 122 and the roofing materials 220, 230, an end watertight material 122m is provided between the ends of the roofing materials 220, 230 and the roof end facing portion 122b. Therefore, even if water on the upper surface of the roofing materials 220, 230 advances toward the front frame 122 due to the effects of strong winds, for example, the watertight material 122m will stop the water from leaking downwards of the roofing materials 220, 230. Moreover, the front contact surface 122g of the front frame 122 that abuts against the roofing materials 220, 230 is provided on the inner circumference side of the front roofing material support portion 122a, and the portion on the end side of the roofing materials 220, 230 is lower, forming a non-contact front frame watertight space 122i with respect to the roofing materials 220, 230. Therefore, even if water that has seeped around the ends of the roofing material 220, 230 travels along the underside 220a1, 230a1 towards the rear frame 123, it can be stopped from dripping off midway, preventing it from progressing towards the inner circumference. In addition, similar to the rear frame 123, a watertight material 122h is provided between the underside 220a1, 230a1 of the roofing material 220, 230, thus preventing water from progressing towards the inner circumference. Furthermore, according to the roof structure 20 described above, a front frame water receiving gutter 122k is provided in the inner circumference portion below the front roofing material support portion 122a. Therefore, even if water exceeds the watertight material 122h and reaches the inner circumference, it will be caught by the front frame water receiving gutter 122k, eliminating the risk of water leakage. Incidentally, water dripping in the front frame water-stopping space 122i and water received in the front frame water-receiving gutter section 122k are discharged through one of the ends to the drainage gutter section 121g of the side frame 121, and then guided by the drainage gutter section 121g before being discharged to the ground G as appropriate.

[0034] In the above-described embodiment, a carport is used as an example, but the method can be applied to other outdoor structures that have a roof structure supported by a support structure. Also, although the example shows a support structure with two columns and two pillars, the number of support structures is not limited to this. Furthermore, although the roof structure is supported in such a way that the rear frame is lower than the front frame relative to the support structure, the roof structure may also be supported so that the front and rear frames are at the same height. Moreover, although the side frames are shown aligned with the direction of beam extension, that is, the front frame is perpendicular to the direction of beam extension, the method is not necessarily limited to this, and it is acceptable as long as the front frame intersects with the direction of beam extension.

[0035] As described above, the outdoor structure according to the present invention is an outdoor structure comprising a support structure composed of columns and beams, and a roof structure in which a plurality of roofing materials are arranged side by side along the longitudinal direction of the front frame between a front frame and a rear frame, wherein the roofing materials are installed between the front frame and the rear frame with their lower surfaces positioned above the lower surfaces of the front frame and the rear frame, and the roof structure is supported by the support structure via the lower surfaces of the front frame and the rear frame with the extending direction of the front frame intersecting the extending direction of the beams. According to this invention, the roofing material is installed so that its lower surface is positioned above the front and rear frames, and the front and rear frames on which the roofing material is installed are directly supported by the support structure. As a result, a space can be secured between the roofing material and the beams without requiring upper beams or support members, which not only improves the aesthetic appeal but also allows for lighting effects without exposing lighting fixtures to the outside, thereby improving the overall appearance.

[0036] Furthermore, the present invention is characterized in that, in the above-described outdoor structure, the roof structure is supported by the support structure such that the rear frame is lower than the front frame, the rear frame is provided with a horizontal gutter section extending along its longitudinal direction, and a vertical gutter is provided inside the support column in a manner that communicates with the horizontal gutter section. According to this invention, water on the upper surface of the roof structure can be drained to the ground by the horizontal gutter section of the rear frame and the vertical gutter of the support column, eliminating the risk of water leakage from the roof structure. Moreover, since the vertical gutter is installed inside the support column, it is also advantageous in terms of appearance quality.

[0037] Furthermore, the present invention is characterized in that, in the above-described outdoor structure, the support columns and beams are each constructed in a hollow manner, and are connected to each other by connecting brackets inserted into the interior from their respective end faces, and the connecting brackets are fixed to the beams by screwing connecting members into the beams from the upper part of the beams, and to the support columns by screwing connecting members into the outer peripheral surfaces of the support columns. According to this invention, the connecting bracket that connects the support column and the beam is fixed by screwing the connecting member onto the upper part of the beam and the outer surface of the support column. As a result, the connecting member is less visible from the outside, which is advantageous in terms of appearance quality. [Explanation of symbols]
