Description

[Technical Field]

[0001] The present invention relates to outdoor structures such as carports. [Background technology]

[0002] Some outdoor structures, such as carports, have roof support members such as beams that are parallel to each other and are attached to the upper portions of multiple pillars, with the roof body supported by the roof support members. The roof body is constructed by arranging multiple roof members side by side, and is installed so as to span the underside of the roof support members (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-90171 Summary of the Invention [Problem to be solved by the invention]

[0004] In order to maximize the rain protection area covered by the roof structure, it is necessary to install the roof structure as close to the pillars as possible. However, when attaching the roof material to the roof support material in the area close to the pillars, work such as screwing into the roof support material is required at the corner between the pillar and the roof support material, so there is still room for improvement in terms of workability during assembly.

[0005] In view of the above circumstances, an object of the present invention is to provide an outdoor structure that can ensure as large a rain shelter area as possible without impairing workability during assembly. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the outdoor structure of the present invention is an outdoor structure comprising two horizontal members arranged parallel to each other on the upper part of a pillar, and a roof support member arranged between the inner faces of the two horizontal members, with a roof body supported on the underside of the roof support member, wherein the roof body is formed by arranging roof members parallel to each other along the horizontal members, and the horizontal members have an inward extending portion that extends inward beyond the inner face of the pillar with their undersides continuous. The outdoor structure of the present invention is an outdoor structure comprising two horizontal members arranged parallel to each other on the upper part of a pillar, and a roof support member arranged between the inner faces of the two horizontal members, with a roof body supported on the underside of the roof support member, characterized in that the roof body is formed by arranging roof members longitudinally along the horizontal members in parallel with each other, and the underside of the horizontal member has an inward extension portion that extends inward beyond the inner face of the pillar. [Effects of the Invention]

[0007] According to the present invention, the inward extension portion functions as part of the roof body, and the roof material closest to the pillar simply needs to be connected to the inward extension portion that extends further inward than the inner surface of the pillar, making it possible to ensure a large rain protection area without compromising workability during assembly. In addition, according to the present invention, the inward extension portion functions as part of the roof body, and the roof material closest to the pillar can be connected to the inward extension portion that extends further inward than the inner surface of the pillar, making it possible to ensure a large rain protection area without compromising workability during assembly.

DETAILED DESCRIPTION OF THE INVENTION

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of an outdoor structure according to the present invention will now be described in detail with reference to the accompanying drawings.

[0010] (Embodiment 1) 1 to 8 show an outdoor structure according to a first embodiment of the present invention. The outdoor structure illustrated here is a carport with a rectangular outer shape intended to accommodate a flat parking space, and is configured with a front pillar 10A, a rear pillar 10B, left and right beams (horizontal members) 20, a plurality of purlins (roof support members) 30, and a roof body 40.

[0011] The front columns 10A and rear columns 10B are extruded members made of metal such as aluminum alloy, and are erected vertically at the front and rear portions of both sides of the parking space. Although not explicitly shown in the figures, in this first 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 protrusion dimension from the ground of the rear columns 10B is set to be lower than that of the front columns 10A. The protrusion dimensions of the two front columns 10A are equal to each other, and the protrusion dimensions of the two rear columns 10B are equal to each other.

[0012] The beam 20 is an extruded member formed from a metal such as an aluminum alloy, and is configured to have a symmetrical shape on the left and right. In this embodiment 1, the beam 20 is configured to include a beam main body portion 21, a purlin connecting portion 22, an outward extending portion 23, and an inward extending portion 24. The beam main body portion 21 and the purlin connecting portion 22 each have a rectangular tubular cross section. The beam main body portion 21 has a width along the left and right directions that is approximately equal to the width along the left and right directions of the front column 10A, and is configured to have a horizontally elongated rectangular cross section with a height dimension smaller than its width dimension. The purlin connecting portion 22 has a width along the left and right directions that is smaller than the width along the left and right directions of the front column 10A, and is configured to have a vertically elongated rectangular cross section with a height dimension larger than its width dimension. The purlin connecting portion 22 is provided on the upper part of the beam main body portion 21, with its inner surface 22a on the inner side being on the same plane as the inner surface 21a on the inner side of the beam main body portion 21. The outward extension portion 23 and the inward extension portion 24 extend approximately horizontally from both lower sides of the beam main body portion 21 in directions away from each other, and then extend approximately vertically upward, forming gutter portions 23a, 24a that open upward between them and the beam main body portion 21. The lower surfaces of the outward extension portion 23 and the inward extension portion 24 are each continuous with the lower surface of the beam main body portion 21 and are located on the same plane as the lower surface of the beam main body portion 21. The upward extension dimension of the outward extension portion 23 and the inward extension portion 24 is approximately equal to the height dimension of the beam main body portion 21. The outward extension dimension of the outward extension portion 23 is approximately equal to the inward extension dimension of the inward extension portion 24. The outward extending portion 23 is provided with a side frame connecting piece 23b on its upwardly extending portion, and the inward extending portion 24 is provided with a roof connecting piece 24b and a roof connecting groove 24c on its upwardly extending portion. The side frame connecting piece 23b extends inwardly almost horizontally from the upper edge of the outward extending portion 23. The roof connecting piece 24b extends inwardly almost horizontally from the upper edge of the inward extending portion 24. The roof connecting groove 24c is a groove that opens downward, and is provided in the lower portion of the inner surface 24d of the inward extending portion 24. The longitudinal dimensions of the beam main body 21, the outward extension 23, and the inward extension 24 are approximately the same as the longitudinal dimensions of the roof body 40, and the purlin connection portion 22 is set so that the longitudinal dimension is shorter than the longitudinal dimension 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 portion 22 are on the same plane. Caps 22b and 22c are attached to the front and rear ends of the purlin connecting portion 22, respectively.

[0013] The beam 20 is attached to a section extending from the upper end of the front column 10A to the upper end of the rear column 10B, with the inner surface 21a of the beam main body 21 being flush with the inner surface 10Aa of the front column 10A and the inner surface 10Ba of the rear column 10B. More specifically, a reinforcing member 25 is disposed inside the cylindrical interior of the beam main body 21, and a beam bracket 10b is attached inside each of the cylindrical interiors of the front column 10A and the rear column 10B. The beam 20 is installed between the front column 10A and the rear column 10B by threading a screw 26 into the reinforcing member 25 via the beam bracket 10b and the beam main body 21. In this state, the front end of the purlin connecting portion 22 is located forward of the front column 10A, and the rear end is located rearward of the rear column 10B.

[0014] The purlin 30 is an extruded member formed from a metal such as an aluminum alloy, and has a purlin base 31 with a rectangular cylindrical cross section, and roof support fins 32 extending on both sides from the lower edge of the purlin base 31. In the example shown, the height of the purlin 30 is set so that when it is placed on the inward extensions 24 of the beams 20 via the roof support fins 32, it is approximately the same as the height of the purlin connecting parts 22. The dimension along the length of the purlin 30 is set so that it is approximately the same as the distance between the inner faces 22a of the purlin connecting parts 22 of the left and right beams 20. A plurality of these purlins 30 are arranged side by side between the left and right beams 20, approximately perpendicular to the length of the beams 20, with each end resting on the upper surface of the inward extensions 24. More specifically, purlin connecting brackets 33 are provided at appropriate locations on the purlin connecting sections 22, and the purlins 30 are arranged at approximately equal intervals between the beams 20 by inserting the purlin connecting brackets 33 into the cylindrical interior of the purlin base 31 and threading screws 34 into the purlin connecting brackets 33 via the purlin base 31. Notches 31a that open downward are provided at the ends of the purlin base 31. Therefore, by placing the purlins 30 between the beams 20 from above so that the purlin connecting brackets 33 pass through the notches 31a, the purlin connecting brackets 33 that have been attached to the left and right beams 20 in advance can be positioned inside the cylindrical interior of the purlin base 31, making it possible to simplify the installation work of the purlins 30.

[0015] The roof structure 40 is constructed in a panel-like configuration by arranging multiple roofing materials 41 side by side. The roofing materials 41 are supported on the underside of the purlin 30 with their longitudinal axes aligned with the longitudinal axes of the beams 20. The roofing materials 41 are extruded shapes formed from metal such as aluminum alloy, and include a reference wall portion 41a, a support side wall portion 41b, a hanging side wall portion 41c, a support piece portion 41d, a hanging piece portion 41e, a connecting protrusion portion 41f, and a connecting groove portion 41g. The reference wall portion 41a is a flat plate extending horizontally. The longitudinal dimension of the reference wall portion 41a is approximately the same as the longitudinal dimension of the roof structure 40. The support side wall portion 41b and the hanging side wall portion 41c extend upward from both side edges of the reference wall portion 41a, each approximately parallel to the other. The extension dimension of the hanging side wall portion 41c is approximately equal to the height dimension of the beam body portion 21. The extension dimension of the receiving side wall portion 41b is configured to be smaller than the extension dimension of the hanging side wall portion 41c by approximately the plate thickness of the hook portion 41e. The receiving portion 41d extends approximately horizontally at the upper edge of the receiving side wall portion 41b in a direction away from the hanging side wall portion 41c. The hook portion 41e extends approximately horizontally at the upper edge of the hanging side wall portion 41c in a direction away from the receiving side wall portion 41b. The extension dimension of the hook portion 41e is longer than that of the receiving portion 41d, and the extending edge of the hook portion 41e is bent downward. The connecting protrusion portion 41f extends approximately horizontally from the lower edge of the receiving side wall portion 41b in the same direction as the receiving portion 41d, and then bends upward. This connecting protrusion 41f is configured so that it can be inserted into the roof connecting groove 24c when the lower surface of the reference wall portion 41a is aligned with the lower surface of the beam 20 and the inward extending portion 24 is adjacent to the connecting groove 41g. The connecting groove 41g is a groove-shaped portion that opens downward and is provided in the lower portion of the hanging side wall portion 41c. In this embodiment 1, the connecting groove 41g is configured so that it has approximately the same shape as the roof connecting groove 24c provided in the beam 20. That is, the roof materials 41 of this embodiment 1 are arranged side by side with the lower surfaces of the reference wall portions 41a aligned, and when the receiving piece portion 41d provided on one roof material 41 is overlapped with the hanging piece portion 41e provided on the other roof material 41, the connecting protrusion 41f provided on one roof material 41 is configured so that it can be inserted into the connecting groove 41g provided on the other roof material 41.Therefore, by arranging a plurality of roof materials 41 in a row, it is possible to construct a roof body 40 with a substantially flat lower surface.

[0016] This roof body 40 can be supported by the purlin 30 without any gaps between them by overlapping the receiving piece 41e onto the receiving piece 41d, and then abutting the receiving piece 41e against the underside of the purlin 30 and threading screws 42 into the receiving piece 41e and the receiving piece 41d via the roof support fin 32. The roof materials 41 located on both sides of the roof body 40 are connected to the inward extending portion 24 of the beam 20 by overlapping the receiving piece 41d onto the underside of the roof connecting piece 24b and threading screws 42 into the roof connecting piece 24b and the receiving piece 41d via the roof support fin 32. The portion of the roof body 40 that is connected to the other beam 20 uses an end roof material 41' having receiving side walls 41b and receiving pieces 41d on both sides of the reference wall 41a, and is connected to the beam 20 in a similar manner.

[0017] As described above, the roofing materials 41 and end roofing materials 41' provided on both sides of the roof structure 40 can be connected to the beams 20 by using the inward extensions 24 that extend inward beyond the inner surfaces 10Aa of the front columns 10A and the inner surfaces 10Ba of the rear columns 10B. In other words, the work of connecting the roofing materials 41 can be performed at a position away from the purlin connections 22 of the front columns 10A and the rear columns 10B and the beams 20. Therefore, when performing work such as threading the screws 42, the front columns 10A and the rear columns 10B and the purlin connections 22 do not get in the way, and the work does not become complicated. Moreover, the inward extensions 24 and outward extensions 23 provided on the lower portions of the beams 20 function as part of the roof structure 40, making it possible to ensure a rain shelter area larger than the actual area of ​​the roof structure 40. In addition, the undersides of these inward extending portions 24 and outward extending portions 23 are flat surfaces that are located on the same plane as the undersides of the beams 20 over their entire width, and are located on the same plane as the undersides of the roof material 41. Therefore, the lower portions of the beams 20 are visually recognized as the roof material 41, in other words, a large rain protection area is secured without any sense of incongruity, and there is no concern that the appearance quality will be impaired.

[0018] As described above, the roof structure 40, supported by the front columns 10A and rear columns 10B via the purlins 30 and beams 20, is inclined so that it gradually lowers from the front to the rear. A rear gutter 43 is provided on the lower, left-right direction at the rear edge of the roof structure 40, located behind the roofing material 41. The rear gutter 43 collects rainwater and other water that drips onto the roofing material 41 and the inward and outward extensions 24 and 23 of the beams 20 and is guided rearward. It has a left-right opening between the front wall 43a and the rear wall 43b. A drainage pipe 43c is provided in the front portion of the rear gutter 43, connecting it to the drainage space 10Bc provided in the rear column 10B. A rear frame 44 is provided along the entire length of the rear wall 43b of the rear gutter 43. Side frames 45 attached to the outward extensions 23 of the beams 20 are connected to both ends of the rear frame 44. The front ends of the side frames 45 are connected to a front frame 46 that extends from the front end of the beam main body 21 to the front end of the roof material 41.

[0019] As described above, in this carport, the inward extending portions 24 and outward extending portions 23 each function as part of the roof body 40, ensuring a large rain protection area. Moreover, the roof materials 41, 41' closest to the front column 10A and the rear column 10B only need to be connected to the inward extending portions 24 that extend inward beyond the inner surfaces 10Aa, 10Ba of the front column 10A and the rear column 10B, respectively, so workability during assembly is not impaired. However, the beams 20 do not necessarily need to have the outward extending portions 23; it is sufficient if they have the inward extending portions 24.

[0020] Furthermore, the beams 20 are configured so that the total length of the purlin connecting portions 22 along the roof material 41 is shorter than the beam main body 21, the inward extending portions 24, and the outward extending portions 23, making it difficult to see the purlin connecting portions 22 when viewing the carport from the front. Furthermore, the outer surface 22d of the purlin connecting portions 22, which is located on the outer side, is located more inward than the outer surface 10Ab of the front column 10A and the outer surface 10Bb of the rear column 10B, making it difficult to see the purlin connecting portions 22 when viewing the carport from the side. In particular, in the first embodiment, the outward extending portions 23 are provided, making it even more difficult to see the purlin connecting portions 22. As a result, the appearance quality of the carport is advantageous.

[0021] In the first embodiment described above, the inward extending portion 24 and the outward extending portion 23 are exemplified as being trough-shaped and open upward, but the present invention is not limited thereto. For example, as shown in Modification 1 in FIG. 9 , a beam 120 having an inward extending portion 124 and an outward extending portion 123 with a hollow cross-sectional shape may be applied. Modification 1 achieves the effect of improving the strength of the beam 120 in addition to the effects of the first embodiment described above. However, even in Modification 1, the beam 120 does not necessarily have to have an outward extending portion 123. Furthermore, both the inward extending portion 124 and the outward extending portion 123 do not necessarily have to have a hollow cross-sectional shape; either one may be configured to be hollow. In Modification 1, the same reference numerals are used to designate components similar to those in the first embodiment.

[0022] Furthermore, in the above-described first embodiment, the beam 20 is configured so that the inward extension portion 24 protrudes inward beyond the inner surface 22a of the purlin connecting portion 22, but the inward extension portion 24 does not need to protrude inward beyond the purlin connecting portion 22. It is sufficient for the inward extension portion 24 to protrude inward beyond the inner surface 10Aa of the front column 10A and the inner surface 10Ba of the rear column 10B. That is, in the beam 220 of the second modified example shown in FIG. 10, the beam main body portion (inward extension portion) 221 and the purlin connecting portion 222 are configured to have the same width dimension, and the inner surface 221a of the beam main body portion 221 is configured to be located on the same plane as the inner surface 222a of the purlin connecting portion 222. A roof connecting piece portion 24b and a roof connecting groove portion 24c are provided on the inner side of the beam main body portion 221, and a hollow outer hollow portion (outward extension portion) 223 is provided on the outer side of the beam main body portion 221. The outer hollow portion 223 is configured to have a horizontally long rectangular cross-sectional shape with the same height as the beam main body portion 221.

[0023] This beam 220 is attached between the front column 10A and the rear column 10B in a state in which a portion located on the inner side of the beam main body 221 protrudes inward beyond the inner surface 10Aa of the front column 10A and the inner surface 10Ba of the rear column 10B, and a portion located on the outer side of the outer hollow portion 223 protrudes outward beyond the outer surface 10Ab of the front column 10A and the outer surface 10Bb of the rear column 10B. In other words, in this beam 220, the portion of the beam main body 221 that protrudes inward beyond the inner surface 10Aa of the front column 10A and the inner surface 10Ba of the rear column 10B functions as an inward extending portion. Similarly, the portion of the outer hollow portion 223 that protrudes outward beyond the outer surface 10Ab of the front column 10A and the outer surface 10Bb of the rear column 10B functions as an outward extending portion.

[0024] In the carport of Modification 2, the beam main body 221 functions as the roof body 40, and the outer hollow portion 223 also functions as the roof body 40, ensuring a large rain shelter area. Furthermore, the roof members 41, 41' closest to the front column 10A and the rear column 10B can be connected to the beam main body 221 extending inward beyond the inner surface 10Aa of the front column 10A and the inner surface 10Ba of the rear column 10B, so assembly workability is not compromised. Furthermore, the width of the purlin connecting portion 222 can be made large, which is advantageous for the strength of the beam 220. However, even in Modification 2, the beam 220 does not necessarily need to have the outer hollow portion 223. Note that the same reference numerals are used in Modification 2 to designate components similar to those in Embodiment 1.

[0025] Furthermore, in the above-described first embodiment, the rear columns 10B are provided at the rear edge of the roof body 40, but as in Modification 3 shown in Figures 11 to 13, the rear columns 10B may be provided at a position forward of the rear edge of the roof body 40. In the carport of Modification 3, the distance between the rear gutter 43 provided at the rear edge of the roof body 40 and the rear columns 10B is large, making it difficult to drain water from the rear gutter 43 into the drainage space 10Bc using the drain pipe 43c, as in Embodiment 1. For this reason, in Modification 3, a water collector 47 is provided on the bottom wall of the rear gutter 43, and a vertical gutter 48 is provided on the rear columns 10B, and the water collector 47 and the vertical gutter 48 are connected by a connecting gutter 49.

[0026] Furthermore, in the above-mentioned embodiment 1, the inward extension portion 24 is formed integrally with the beam 20, which is advantageous in terms of the number of parts to be handled and makes assembly easier, but it is also possible to configure the inward extension portion 24 and the beam 20 as separate entities, as in embodiment 2 shown below.

[0027] (Embodiment 2) 14 and 15 show essential parts of an outdoor structure according to a second embodiment of the present invention. Although not explicitly shown in the figures, the outdoor structure illustrated here is a carport that, like the first embodiment, has a rectangular outer shape and is intended to accommodate a flat parking space, but differs from the first embodiment in the configuration of the beams. That is, the carport according to the second embodiment uses beams 320 in which beam main body 321 and purlin connecting portion 322 are integrally formed, and roof connecting members (inward extending portion, outward extending portion) 50 are provided on the underside of beam 320. The following mainly describes the configuration of beams 320 and roof connecting members 50 that differ from the first embodiment, and the same components as those in the first embodiment are designated by the same reference numerals and will not be described in detail.

[0028] The beam main body 321 and purlin connecting portion 322 that make up the beam 320 have substantially the same configuration as those described in embodiment 1. As in embodiment 1, the purlin connecting portion 322 is configured so that its longitudinal dimension is shorter than that of the beam main body 321. The beam main body 321 has a beam-side engaging portion 321a at a corner located on the outward side in its lower portion. The beam-side engaging portion 321a extends substantially horizontally outward, continuing from the underside of the beam main body 321, and then bends upward.

[0029] The roof connecting member 50 is an extruded member formed from a metal such as an aluminum alloy, and has a base plate 50a, an outer side wall 50b, and an inner side wall 50c. The base plate 50a is flat and wider than the front columns 10A and the rear columns 10B, and is configured so that its longitudinal dimension is approximately the same as that of the beam main body 321. The outer side wall 50b extends upward almost vertically from the outer edge of the base plate 50a, and the inner side wall 50c extends upward almost vertically from the inner edge of the base plate 50a. In other words, the roof connecting member 50 is configured so that both side edges of the base plate 50a extend upward, forming a concave shape that opens upward. The upward extension dimensions of the outer side wall portion 50b and the inner side wall portion 50c are equal to each other and smaller than the height dimension of the beam main body portion 321. A side frame connecting piece 50d is provided on the outer side wall portion 50b, and a roof connecting piece 50e and a roof connecting groove 50f are provided on the inner side wall portion 50c. The side frame connecting piece 50d extends inwardly almost horizontally from the upper edge of the outer side wall portion 50b. The roof connecting piece 50e extends inwardly almost horizontally from the upper edge of the inner side wall portion 50c. The roof connecting groove 50f is a groove-shaped portion that opens downward and is provided in the lower portion of the inner surface of the inner side wall portion 50c.

[0030] Furthermore, the roof connecting material 50 is provided with a connecting-side engaging portion 50g on the upper surface of the base plate portion 50a. The connecting-side engaging portion 50g is capable of engaging with the beam-side engaging portion 321a when the beam main body portion 321 of the beam 320 is positioned approximately in the center between the outer side wall portion 50b and the inner side wall portion 50c, and is provided over the entire length along the longitudinal direction of the roof connecting material 50. In the second embodiment, the connecting-side engaging portion 50g extends upward from the upper surface of the base plate portion 50a, then extends inward, and the extending edge portion is further bent downward. 15(b), the beam 320 is rotated about an axis along the length so that the beam-side engaging portion 321a can be inserted into the connecting-side engaging portion 50g with the connecting-side engaging portion 50g facing downward, and the beam 320 is then rotated so that the lower surface of the beam main body portion 321 a abuts against the upper surface of the substrate portion 50a, thereby engaging with the beam-side engaging portion 321a. In this state, downward movement of the substrate portion 50a relative to the lower surface of the beam 320 is restricted, and the lower surface of the beam 320 and the upper surface of the substrate portion 50a are constantly maintained in abutting state.

[0031] This roof connecting member 50 is disposed in a section extending from the upper end of the front column 10A to the upper end of the rear column 10B via the base plate portion 50a, with the base plate portion 50a protruding from the inner surface 10Aa and outer surface 10Ab of the front column 10A and protruding from the inner surface 10Ba and outer surface 10Bb of the rear column 10B. From this state, the beam main body 321 is brought into contact with the base plate portion 50a with the beam side engaging portion 321a engaged with the connecting side engaging portion 50g, and the screws 26 are threaded into the reinforcing member 25 via the beam bracket 10b and the beam main body 321, thereby installing the beam 320 between the front column 10A and the rear column 10B. The beam 320 attached to the front column 10A and the rear column 10B has an inner surface 321b of the beam body 321 located on the same plane as the inner surface 10Aa of the front column 10A and the inner surface 10Ba of the rear column 10B, and the front end of the purlin connecting portion 322 is located forward of the front column 10A, and the rear end is located rearward of the rear column 10B. Hereinafter, the carport of the second embodiment is constructed by applying purlins 30 and roof bodies 40 having the same configuration as those in the first embodiment and assembling them in the same manner.

[0032] In this carport, the roof members 41 and end roof members 41' on both sides of the roof structure 40 are simply connected to the inner sidewalls 50c of the roof connecting members 50, which extend inward beyond the inner surfaces 10Aa and 10Ba of the front and rear columns 10A and 10B, respectively. This allows the roof members 41 to be connected at a distance from the front and rear columns 10A and 10B and the beams 320. This eliminates the need for complicated installation work, such as fastening the screws 42, since the front and rear columns 10A and 10B do not get in the way. Furthermore, because the roof connecting members 50 function as part of the roof structure 40, it is possible to provide a rain shelter area larger than the actual area of ​​the roof structure 40. Additionally, the underside of the roof connecting members 50 is a flat surface that lies flush across its entire width and is flush with the underside of the roof members 41. Therefore, the roof connecting members 50 are visually recognized as the roof members 41. In other words, a large rain shelter area is secured without any sense of incongruity, and there is no concern that the appearance quality will be impaired. Furthermore, the beams 320 and the roof connecting members 50, which are constructed separately, are engaged with each other by the beam-side engaging portions 321a and the connecting-side engaging portions 50g. Therefore, there is no concern that problems such as gaps will occur between the beams 320 and the roof connecting members 50 when, for example, snow accumulates on the roof and the roof structure 40 bends downward. In the second embodiment as well, the roof connecting members 50 do not need to extend outward beyond the outer surfaces 10Ab of the front columns 10A and the outer surfaces 10Bb of the rear columns 10B; it is sufficient that they extend inward beyond the inner surfaces 10Aa of the front columns 10A and the inner surfaces 10Ba of the rear columns 10B. It is sufficient that the above-mentioned beam side engagement portion 321a and connecting side engagement portion 50g are provided at least in the portion corresponding to the area between the front column 10A and the rear column 10B, and they do not necessarily have to be provided along the entire length of the beam 320 or the roof connecting material 50.

[0033] In the above-described embodiment, a carport is used as an example of an outdoor structure, but it is not necessarily limited to a carport as long as it has pillars, cross members, roof support members, and a roof body. In this case, the pillars do not necessarily have to include front pillars and rear pillars; it is sufficient to include either pillar. Furthermore, the specific configurations of the pillars, beams, purlins, and roof members are not limited to those in the embodiment.

[0034] As described above, the outdoor structure of the present invention is an outdoor structure comprising two horizontal members arranged parallel to each other on the upper part of a pillar, and a roof support member arranged between the inner faces of the two horizontal members, with a roof body supported on the underside of the roof support member, wherein the roof body is formed by arranging roof members longitudinally along the horizontal members in parallel with each other, and the horizontal members have inward extending portions that extend inward beyond the inner faces of the pillars with their undersides continuous. According to this invention, the inward extension portion functions as part of the roof body, and the roof material closest to the pillar simply needs to be connected to the inward extension portion that extends further inward than the inner surface of the pillar, making it possible to ensure a large rain protection area without compromising workability during assembly.

[0035] Furthermore, in the above-described outdoor structure of the present invention, the cross member has an outward extending portion that extends outward beyond the outer surface of the column with its lower surface continuing. According to this invention, the outward extension functions as part of the roof body, so that a larger rain protection area can be secured.

[0036] The outdoor structure of the present invention is an outdoor structure comprising two horizontal members arranged parallel to each other on the upper part of a pillar, and a roof support member arranged between the inner faces of the two horizontal members, with a roof body supported on the underside of the roof support member, wherein the roof body is formed by arranging roof members parallel to each other along the horizontal members, and the underside of the horizontal members has an inward extension portion that extends inward beyond the inner face of the pillar. According to this invention, the inward extension functions as part of the roof body, and the roof material closest to the pillar can be connected to the inward extension that extends inward beyond the inner surface of the pillar, so it is possible to secure a large rain protection area without impairing workability during assembly. Moreover, since the cross members are hidden by the inward extension when the roof body is viewed from below, it is also advantageous in terms of appearance quality.

[0037] Furthermore, the present invention is characterized in that, in the outdoor structure described above, an outward extension portion is provided on the underside of the cross member, which extends outward beyond the outer surface of the column. According to this invention, the outward extension functions as part of the roof body, so that a larger rain protection area can be secured.

According to this invention, the horizontal members are less visible when viewed from the end side of the roofing material, which is advantageous in terms of appearance quality.

[0039] Furthermore, the present invention is characterized in that, in the outdoor structure described above, the connecting portion is configured so that its outer surface is positioned more inward than the outer surface of the pillar. According to this invention, the cross member is difficult to see when viewed from the outside of the cross member, which is advantageous in terms of appearance quality.

[0040] Furthermore, the present invention is characterized in that in the outdoor structure described above, the roof material is provided so that its lower surface is positioned on the same plane as the lower surface of the inward extension portion. According to this invention, when the roof body is viewed from below, the inward extension portion is recognized as part of the roof material, which is advantageous in terms of appearance quality.

[0041] Furthermore, the present invention is characterized in that in the outdoor structure described above, at least one of the inward extension portion and the outward extension portion is provided so as to form a gutter shape with an open upper surface. According to this invention, the gutter-shaped portion can function as a gutter, eliminating the need to provide a separate gutter, which is advantageous in terms of manufacturing costs and assembly work.

[0042] Furthermore, the present invention is characterized in that in the outdoor structure described above, at least one of the inward extension portion and the outward extension portion is provided so as to have a hollow cross-sectional shape. According to this invention, the strength of the portion configured to have a hollow cross-sectional shape can be improved.

[0043] Furthermore, in the outdoor structure of the present invention, the connecting portion is configured so that an inner surface thereof is positioned on the same plane as an inner surface of the inward extending portion. According to this invention, the width dimension of the cross member can be made large, which is advantageous in terms of strength.

[0044] Furthermore, the present invention is characterized in that in the outdoor structure described above, an engaging portion is provided between the inward extending portion and the horizontal member, so that they can engage with each other. According to this invention, the horizontal member and the inward extending portion are engaged with each other between the posts, so there is no risk of a gap being generated between them when the posts are bent downward.
