DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figures 1 to 11 show a first embodiment of a structure of the present invention. This structure is applied to a carport for one passenger car that is installed on the site of a house. 1 to 5, this structure comprises two pillars 1,1 standing on the left side as viewed from the front with a gap between them in the front-to-rear direction, two beams 2,2 supported on the upper ends of the pillars 1,1, respectively, and a roof 3 supported by the beams 2,2. The roof 3 is inclined so that the left side where the pillar 1 is located is lower.

[0010] The pillar 1 is made of an aluminum alloy extrusion and is formed into a hollow shape with a roughly rectangular cross section as shown in Fig. 11. The front and rear facing surfaces 1a, 1b of the pillar 1 protrude outward beyond the outer (left) facing surface 1c, and a batten 9 is fitted and attached between the end edges to form a vertical gutter 10 integral with the pillar 1 for draining rainwater from the roof 3 to the ground. As shown in Figure 1, the lower part of pillar 1 is inserted into foundation hole 11 formed in the ground, and concrete 12 is packed around pillar 1. In order to install this structure near neighboring property boundary 13, foundation hole 11 is provided close to neighboring property boundary 13, and pillar 1 is positioned eccentrically on the neighboring property boundary 13 side. A predetermined distance A (specifically, about 80 mm) is provided between pillar 1 and foundation hole 11. As shown in FIG. 9, the beam 2 is also formed from an aluminum alloy extruded member into a hollow shape having a substantially rectangular cross section. As shown in Fig. 6, the pillar 1 and the beam 2 are connected by inserting an L-shaped pillar-beam connecting bracket 14 into the hollow parts of the pillar 1 and the beam 2 and fixing them with a bolt 15. The underwater (left side) end of the beam 2 protrudes outward beyond the pillar 1.

[0011] As shown in Figure 2, the roof 3 has a retaining frame 7 formed by a front frame 4, a rear frame 5, and left and right side frames 6a, 6b in a rectangular shape, and a number of roof materials 8, 8, ... arranged in the left-right direction inside the retaining frame 7 and installed in a line in the front-to-back direction. The right side frame 6a, located above the water, is fixed to the above-water ends of the front and rear beams 2 with L-shaped metal fittings 16, as shown in Figure 6. The above-water side frame 6a is made of an aluminum alloy extrusion and has a cross section shaped like a right-angled triangle with the upper surface sloping downward toward the outer periphery of the roof 3.

[0012] The front frame 4 and the rear frame 5 are formed from aluminum shaped material with a roughly right-angled triangular cross section, similar to that of the above-water side frame 6a, as shown in Figure 9. Both longitudinal ends of the above-water side frame 6a and the above-water ends of the front frame 4 and the rear frame 5 are each cut at an angle of 45°, as shown in Figure 2, and the diagonally cut ends are butted together and connected.

[0013] The left side frame 6b located underwater is fixed and attached to the underwater ends of the front and rear beams 2 with L-shaped metal fittings 17 as shown in FIG. 6. The underwater side frame 6b is formed of an aluminum alloy extrusion, and has a body 18 with a substantially rectangular cross section connected to the beam 2 with metal fittings 17, and a horizontal gutter 19 attached by screwing to the lower part of the outer circumferential side of the body 18. The upper end of the part of the pillar 1 that protrudes from the visible surface 1c of the front and rear visible surfaces 1a, 1b is notched, and the horizontal gutter 19 is swallowed into the notch 20, and the inner circumferential side surface abuts against the visible surface 1c of the pillar 1. Therefore, the entire underwater side frame 6b, including the body 18 and the horizontal gutter 19, is located outside the visible surface 1c of the pillar 1. In this way, the entire underwater side frame 6b is located outside the visible surface 1c of the pillar 1, so that the projection dimension B (see FIG. 1) of the roof 3 from the pillar 1 is large. Specifically, the projection dimension B of the roof 3 from the pillar 1 is approximately equal to or greater than the predetermined dimension A between the pillar 1 and the foundation hole 11. This allows the roof 3 to be easily extended right up to the boundary 13 when this structure is installed near the boundary 13 (see Figure 1).

[0014] As shown in Fig. 6, the horizontal gutter 19 has a drain hole 21 formed in the part that is swallowed into the notch 20 of the pillar 1, and rainwater that enters the horizontal gutter 19 flows from the drain hole 21 to the vertical gutter 10 provided on the outside of the pillar 1, and is drained to the ground from a drainage outlet 22 (see Fig. 1) that opens outward at the lower end of the vertical gutter 10. The upper end of the vertical gutter 10 is butted against the underside of the horizontal gutter 19.

[0015] As shown in Figures 7 and 8, a water collector 27 is attached to the underside of the horizontal gutter 19 at the position where the drainage hole 21 is provided, in order to prevent the generation of drainage noise. The water collector 27 is made of resin, and as shown in Figures 12 and 13, the top is open, and drainage holes 28a are formed on the front and rear side surfaces, and drainage holes 28b, 28c are also formed on the outer (left side) and inner (right side) side surfaces. A plate-shaped water stopper 29 is provided hanging down from the upper part of the outer side surface. The bottom surface of the water collector 27 forms an inclined surface 30 that slopes downward as it goes outward. As shown in Fig. 12(a), the inclined surface 30 is divided into a front side and a rear side, and a bulging portion 31 that bulges upward and has an inverted U-shaped cross section is formed between them. The water collector 27 has the bulging portion 31 formed in this way to allow the head of the bolt 15 that fixes the column-beam connecting fitting 14 to the column 1 to escape. 7 and 8, the upper surface of the water collector 27 abuts against the lower surface of the horizontal gutter 19 at the position where the drainage hole 21 is provided, and is attached by screwing it in place with screws 32 from below. The lower edge 30a of an inclined surface 30 formed at the bottom of the water collector 27 is spaced from the inner surface of the outer wall of the vertical gutter 10. The size of the gap 33 between the lower edge 30a of the inclined surface 30 and the inner surface of the outer wall of the vertical gutter 10 is 2 to 3 mm, specifically 2.3 mm.

[0016] As shown in Figures 7 and 8, rainwater that enters the horizontal gutter 19 falls from the drainage holes 21 of the horizontal gutter 19 onto the bulge 31 of the water collector 27 and splits into the front and rear sides, and most of the rainwater flows into the vertical gutter 10 from the drainage holes 28a formed on the front and rear sides of the water collector 27 as indicated by arrow 34 in the figures. Some of the rainwater flows from the inclined surface 30 formed at the bottom of the water collector 27 along the inner surface of the outer wall of the vertical gutter 10 as indicated by arrow 35 in the figures (a drainage path that guides rainwater along the inner surface of the vertical gutter 10). When there is little rain or immediately after the rain has stopped, rainwater mainly flows along the drainage path indicated by arrow 35.

[0017] If the above-mentioned water collector 27 were not installed when there was little rain or immediately after the rain had stopped, water droplets falling from the drainage holes 21 of the horizontal gutter 19 would collide with the drainage outlet 22 provided at the bottom of the vertical gutter 10, generating a "plop, plop" sound. As described above, this structure has a drainage path 35 that guides rainwater from the inclined surface 30 formed at the bottom of the water collector 27 along the inner surface of the outer wall of the vertical gutter 10, thereby making it possible to prevent the generation of such drainage sounds. The water collector 27 has a drainage hole 28b formed on the outer side located on the lower edge 30a side of the inclined surface 30, and also has drainage holes 28a, 28c formed on the front, rear and inner side surfaces, so that rainwater can be drained into the vertical gutter 10 through these drainage holes 28a, 28b, 28c, and therefore rainwater can flow smoothly from the horizontal gutter 19 to the vertical gutter 10 even when there is a heavy rainfall. Furthermore, the water collector 27 has a water stopper 29 formed on the upper part of the outer side, which can prevent water or the like that hits the bulge 31 and bounces off from leaking out from the upper end of the vertical gutter 10. In addition, the water collector 27 has a portion (bulge portion 31) that allows the head of the bolt 15 that fixes the column-beam connecting fitting 14 to the column 1 to escape, so that the water collector 27 can be easily installed even if the head of the bolt 15 protrudes outside the column 1.

[0018] 2 and 9, the roof materials 8 are made of aluminum alloy extruded material in plate form and are attached in a line in the front-to-rear direction between the front frame 4 and the beams 2, between the beams 2, and between the beams 2 and the rear frame 5. A hollow portion 24 with a roughly rectangular cross section is formed in the connection portions 23 between adjacent roof materials 8 (see FIG. 9), which gives strength to the roof 3. As shown in Fig. 6, each roofing material 8 is installed between the two frames 6a, 6b, with its above-water end connected to the above-water side frame 6a with metal fittings 25a and its below-water end connected to the below-water side frame 6b with metal fittings 25b. The below-water end of the roofing material 8 extends beyond the visible surface 1c of the pillar 1 and is absorbed into the below-water side frame 6b, so that rainwater that runs down the top surface of the roofing material 8 falls into the horizontal gutter 19 of the side frame 6b.

[0019] As shown in FIG. 10, each roofing material 8 has minute corrugated irregularities 36, consisting of alternating peaks and valleys with a cross section of a generally arcuate shape, formed continuously in the left-right direction, which is the extrusion direction, over the entire underside. As shown in Figure 9, in this structure, a roof material 26 is also attached under the beam 2, and the underside of the roof material 26 is flush with the undersides of the other roof materials 8, 8, .... The underside of the roof material 26, like the roof material 8, has fine projections and recesses 36 formed all over its surface that run continuously in the left-right direction, which is the extrusion direction. In this structure, fine irregularities 36 are formed continuously in one direction (left and right) across the entire underside of each roof material 8, 8, ... and roof material 26, so that by simply lining up the roof materials 8, 8, ... and roof material 26 inside the retaining frame 7, a flat ceiling 37 is formed on the underside of the roof 3 with a decorative surface with an irregular pattern.

[0020] Furthermore, as shown in Figures 6 and 9, the undersides of the front frame 4, rear frame 5 and above-water side frame 6a that constitute the retaining frame 7 of this structure are flush with the underside of the roof materials 8, 8, ... and, like the underside of the roof material 8, the undersides of the front frame 4, rear frame 5 and above-water side frame 6a are entirely formed with fine irregularities 36 that continue in the extrusion direction (left-right direction for the front frame 4 and rear frame 5, and front-to-back direction for the above-water side frame 6a).

[0021] The fine irregularities 36 formed on the underside of the roofing material 8 etc. preferably have a pitch P of 0.6 mm to 2.5 mm and a depth d of 0.09 mm to 2.0 mm.

[0022] Condensation may occur on the ceiling 37 depending on weather conditions. Figures 14-1 and 14-2 are photographs of the ceiling 37 of this structure, with Figure 14-1 showing the state when no condensation has occurred and Figure 14-2 showing the state when condensation has occurred. The fine irregularities 36 formed on the ceiling 37 have a pitch P of 0.6 mm and a depth d of 0.09 mm. FIG. 15 is a photograph of an aluminum ceiling 100 with no irregularities formed thereon as a comparative example, showing the state when condensation occurs.

[0023] As shown in Figure 15, when condensation occurs on a ceiling 100 that does not have any unevenness, the condensed water droplets gather together to form large droplets 101, which eventually drip due to gravity. If the droplets fall on the bonnet of a car parked underneath, for example, they leave marks. As shown in Figure 14-2 (b), the ceiling 37 of this structure has fine projections and recesses 36 formed thereon, which prevents the fine water droplets produced by condensation from gathering together and growing larger, but instead dries and disappears while remaining attached to the ceiling 37, thereby preventing condensation droplets from dripping from the ceiling 37.

[0024] In addition, the ceiling 37 of this structure has minute projections 36 formed all over it, which reduces glare and prevents the space under the roof from getting hot due to the heat dissipation effect of the increased surface area. In addition, there are other effects such as the die lines being invisible, the color differences between the shaped materials being inconspicuous, and scratches being inconspicuous.

[0025] 16 to 19 show a second embodiment of the structure of the present invention, which differs from the first embodiment in the shape of the water collector 27. In FIG. As shown in Figures 16 and 18, the water collector 27 of this embodiment is formed in a cylindrical shape with a hanging wall 40 that is open at the top and bottom so as to surround the drainage hole 21 of the horizontal gutter 19, and the hanging wall 40 forms a drainage path 41 that guides rainwater that falls from the drainage hole 21 straight down. Furthermore, as shown in Fig. 16, the water collector 27 has an inclined surface 42a below the left hanging wall 40a, which slopes downward as it goes left, and an inclined surface 42b below the right hanging wall 40b, which slopes downward as it goes right. The left inclined surface 42a is located at a lower position than the right inclined surface 42b. A gap 33 is formed between the lower edges of both inclined surfaces 42a, 42b and the inner surface of the vertical gutter 10. By providing the inclined surfaces 42a, 42b in this manner, the water collector 27 has drainage paths 43a, 43b that guide rainwater that falls from the drainage hole 21 along the inner surface of the vertical gutter 10.

[0026] When there is a lot of rain, the rainwater that enters the horizontal gutter 19 flows straight down through the drainage hole 21 of the horizontal gutter 19 and the drainage path 41 of the water collector 27, as shown in Figures 16 and 17. This allows the rainwater to be drained smoothly even when there is a lot of rain. When the amount of rain is small or immediately after the rain has stopped, as shown in Fig. 16, rainwater runs down the hanging wall 40 of the water collector 27, falls onto the inclined surfaces 42a, 42b, and flows downward through the drainage paths 43a, 43b that are guided from the inclined surfaces 42a, 42b along the inner surface of the vertical gutter 10. This makes it possible to prevent the generation of drainage noise.

[0027] As described above, this structure (first and second embodiments) comprises a horizontal gutter 19, a vertical gutter 10 and a water collector 27, the horizontal gutter 19 has a drainage hole 21, the water collector 27 is attached to the underside of the horizontal gutter 19 at the position where the drainage hole 21 is provided, and has inclined surfaces 30, 42a, 42b whose lower edges are spaced apart from the inner surface of the vertical gutter 10, and has drainage paths 35, 43a, 43b that guide rainwater that falls from the drainage hole 21 along the inner surface of the vertical gutter 10 (see Figures 7 and 16), making it easy and simplifying the construction of the gutter and preventing the generation of drainage noise. This structure (second embodiment) includes a horizontal gutter 19, a vertical gutter 10, and a water collector 27. The horizontal gutter 19 has a drainage hole 21, and the water collector 27 is attached to the underside of the horizontal gutter 19 at the position where the drainage hole 21 is provided. The structure includes a drainage path 41 that guides rainwater that falls from the drainage hole 21 straight down, and drainage paths 43a, 43b that have inclined surfaces 42a, 42b whose lower edges are spaced apart from the inner surface of the vertical gutter 10 and guide the rainwater that falls from the drainage hole 21 along the inner surface of the vertical gutter 10 (see FIG. 16). This makes it easy to install the rain gutter, simplifies the installation, and prevents the generation of drainage noise. The water collector 27 has a drainage path 41 that guides rainwater that falls from the drainage hole 21 straight down, allowing the rainwater to flow smoothly into the vertical gutter 10, improving drainage. The water collector 27 of the second embodiment has a hanging wall 40 hanging downward from the drainage hole 21, and inclined surfaces 42a, 42b are provided below the hanging wall 40 (see Figure 16), which allows rainwater to flow smoothly straight down when there is a lot of rain, and when there is little rain, the rainwater can be reliably guided along the inner surface of the vertical gutter 10 via the hanging wall 40 and inclined surfaces 42a, 42b. The water collector 27 of the first embodiment has drainage holes 28a, 28c formed on at least one side surface other than the side surface on the lower edge 30a side of the inclined surface 30 (see Figures 7 and 13), so that rainwater can be drained into the vertical gutter 10 through the drainage holes 28a, 28c, allowing rainwater to flow smoothly from the horizontal gutter 19 to the vertical gutter 10 even when there is a heavy rainfall. The water collector 27 of the first embodiment has a water-stopping portion 29 at the top that prevents rainwater from leaking out from the upper end of the vertical gutter 10 (see Figure 7), thereby preventing rainwater from leaking from the joint between the vertical gutter 10 and the horizontal gutter 19. The water collector 27 of the first and second embodiments has a portion (bulge 31) that avoids the head of the bolt 15 that fixes the column-beam connecting fitting 14 to the column 1 (see Figures 8 and 18), so that the water collector 27 can be easily installed even if the head of the bolt 15 protrudes outside the column 1.

[0028] This structure has a ceiling 37 which has fine projections and recesses 36 formed all over it that run continuously in one direction (see Figure 10). This means that the ceiling 37 can be formed simply by attaching the roof materials 8, 8, ... without the need to attach a ceiling material in addition to the roof materials 8, 8, ..., thus simplifying construction. In addition, by forming fine irregularities 36 that continue in one direction over the entire surface of the ceiling 37, it is possible to prevent condensation water droplets from becoming large and dripping, glare is reduced, and the increased surface area has a heat dissipation effect, preventing the space under the roof from becoming hot. The minute irregularities 36 on the ceiling 37 have a pitch P of 0.6 mm to 2.5 mm and a depth d of 0.09 mm to 2.0 mm, which reliably prevents condensation droplets from becoming large and dripping, and also prevents deterioration of the design and waste of material costs. This structure has a retaining frame 7 that holds a ceiling 37, and fine irregularities 36 are formed on the underside of the retaining frame 7, which is flush with the ceiling 37 (the undersides of the front frame 4, rear frame 5, and side frame 6a above the water), which enhances the design while also preventing condensation water from dripping from the underside of the retaining frame 7.

[0029] The present invention is not limited to the above-described embodiment. The cross-sectional shape and material of the horizontal gutter and vertical gutter can be changed as appropriate. The vertical gutter may be formed separately from the pillar. The shape and material of the water collector can be changed as appropriate. The roof structure is not limited. The present invention can be applied to any structure having a roof, such as a cycle port, a passage shelter, or a terrace roof, in addition to a carport. [Explanation of symbols]
