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 on the bottom of the water collector 27, running down the inner surface of the outer wall of the vertical gutter 10 as indicated by arrow 35 in the figures. When there is little rainfall or immediately after the rain has stopped, the rainwater mainly flows along the 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 allows rainwater to flow 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 preventing 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 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 fine corrugated irregularities 36 formed continuously in the left-right direction, which is the extrusion direction, over the entire underside, with alternating peaks 36a and valleys 36b of approximately isosceles triangular cross section. The tops of the peaks 36a and the bottoms of the valleys 36b are formed in an R-shape. The irregularities 36 are formed in a die for extrusion molding of the roofing material 8, and the irregularities 36 are formed at the same time as the roofing material 8 is extruded. The roofing material 8 has an anodized coating formed on the surface. 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. This structure has fine irregularities 36 formed on the entire underside of each roof material 8, 8, ... and roof material 26 in one direction (left and right), 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 with a design surface with an irregular pattern on the underside of the roof 3. By forming fine irregularities 36 on the entire surface of the ceiling 37 in this way, diffuse reflection of light on the ceiling 37 is suppressed and a matte texture is created, resulting in a luxurious feel.
[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] 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 h 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.
[0022] 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 Fig. 14-2(b), the ceiling 37 of this structure has fine irregularities 36 formed thereon. As a result, the fine water droplets generated by condensation do not coalesce and grow larger, but remain attached to the ceiling 37, dry up, and disappear, preventing the dripping of condensation water droplets from the ceiling 37.
[0023] Also, since the ceiling 37 of this structure has fine irregularities 36 that are continuous in one direction formed over the entire surface, there is an effect that glare is reduced, and due to the heat dissipation effect caused by the increased surface area, the space under the roof does not become hot. Furthermore, there are also effects such as the die line not being visible, the color difference between the profiles not being prominent, and scratches not being prominent.
[0024] Regarding the pitch P and depth h of the irregularities 36, verification was carried out from the viewpoints of water droplet retention (whether the condensation water droplets are retained without falling), smoothness, matte feeling (high-class feeling), safety (whether it does not hurt when touched), cleanability (whether dirt can be removed by simply wiping with a rag, etc.), and aluminum material cost. The evaluation of each item was carried out in four grades of ◎, 〇, △, and ×. The results of the verification are shown in Table 1 below. Note that regarding the evaluation of the aluminum material cost due to the difference in pitch P, since the aluminum material cost does not change even when the pitch P is changed, no evaluation was carried out.
[0025]
Table 1
[0026] As is clear from Table 1, if the pitch P is in the range of 0 < P ≤ 1.5 mm and the depth h is in the range of 0 < h ≤ 0.5 mm (the shaded range in the table), there is no × evaluation in all items, and the evaluation is generally 〇 or higher. Therefore, it is preferable that the irregularities 36 have a pitch P of 0 < P ≤ 1.5 mm and a depth h of 0 < h ≤ 0.5 mm. Also, when the pitch P is in the range of 0.5 < P ≤ 1.0 mm and the depth h is in the range of 0.05 < h ≤ 0.1 mm (the lightly shaded range in the table), the water droplet retention, the matte feeling, and the safety are evaluated as ◎. Therefore, the unevenness 36 is more preferably such that the pitch P is 0.5 < P ≤ 1.0 mm and the depth h is 0.05 < h ≤ 0.1 mm. Note that the evaluation of the aluminum material cost is △ when the depth h is 0.5 < h ≤ 1.0 mm and × when 1.0 mm < h. The reason why it deteriorates as the dimension of the depth h increases is that as the dimension of the depth h increases, it is necessary to increase the wall thickness t2 to ensure a predetermined strength.
[0027] For comparison, specific examples of the unevenness 36 belonging to the lightly shaded range, the darkly shaded range, and the non-shaded range in Table 1 are shown in FIG. 16. FIG. 16(a) has the pitch P and the depth h in the lightly shaded range in Table 1. FIG. 16(b) has the pitch P and the depth h in the darkly shaded range in Table 1. FIG. 16(c) has the pitch P and the depth h in the non-shaded range in Table 1. Among these, for the unevenness 36 of FIG. 16(a) and FIG. 16(b), water droplet retention and a matte feeling can be obtained. In particular, for the one in FIG. 16(a), more excellent water droplet retention and a matte feeling can be obtained.
[0028] FIGS. 17 to 19 show a second embodiment of the structure of the present invention. This structure is applied to a carport for one passenger car in the same manner as the first embodiment. This structure includes two columns 1, 1 standing upright at intervals in the front-rear direction on the right side when viewed from the front, two beams 2, 2 respectively supported at the upper ends of the columns 1, 1, a roof 3 supported by the beams 2, 2, and walls 38 attached to the outer and inner expected surfaces of the columns 1, 1.
[0029] As shown in FIGS. 18 and 19, the roof 3 is configured by attaching a plurality of roof members 8, 8,... in the front-rear direction and arranging them side by side in the left-right direction on the lower surface of the beam 2, 2. As shown in Fig. 19, the roof material 8 is an aluminum alloy extrusion material formed into a plate shape with a hollow portion, and also serves as a ceiling material. A flat ceiling 37 is formed on the underside of the roof 3 by the undersides of the roof materials 8, 8, ... The underside of the roofing material 8 is formed with fine projections and recesses 36 that are continuous in the extrusion direction (front-rear direction) over the entire surface, similar to the roofing material 8 of the first embodiment (see FIG. 10). The roofing material 8 has an anodized coating formed on the surface. As a result, the ceiling 37 of this structure has a matte texture and suppresses diffuse reflection of light, similar to the first embodiment, giving it a luxurious feel. In addition, fine water particles caused by condensation on the ceiling 37 do not gather together and become large, but dry and disappear while remaining attached to the ceiling 37, preventing condensation from dripping from the ceiling 37.
[0030] As shown in Figs. 17 and 19, the wall 38 is configured by attaching a plurality of wall materials 39, 39, . . . to the pillars 1, 1 in a longitudinal direction and arranged in a vertical direction. As shown in Fig. 19, the wall material 39 is an aluminum alloy extrusion material formed into a plate shape having a hollow portion, similar to the roof material 8. The surface of the wall material 39 exposed to the outside (the surface opposite the pillar 1) is formed entirely with fine irregularities 36 that continue in the extrusion direction (front-rear direction), similar to the roof material 8 of the first embodiment (see Fig. 10). The wall material 39 has an anodized coating formed on the surface. As a result, the walls 38 of this structure, like the ceiling 37, are able to suppress diffuse reflection of light and have a matte texture, giving them a luxurious feel. In addition, fine water droplets caused by condensation on the walls 38 do not gather together and become larger, but dry and disappear while remaining attached to the walls 38, preventing condensation from dripping down from the walls 38 and wetting the dirt floor.
[0031] As described above, this structure (first embodiment) includes a horizontal gutter 19, a vertical gutter 10, and a water collector 27. The horizontal gutter 19 has a drain hole 21. The water collector 27 is attached to the lower surface at the position where the drain hole 21 of the horizontal gutter 19 is provided, and has an inclined surface 30 that guides the rainwater falling from the drain hole 21 to the inner surface of the vertical gutter 10. Since the lower edge 30a of the inclined surface 30 is separated from the inner surface of the vertical gutter 10 (see Fig. 7), the construction of the rain gutter is easy, the construction can be simplified, and the generation of drainage noise can be prevented. Since the water collector 27 has drain holes 28a and 28c formed in at least one side surface other than the side surface on the lower edge 30a side of the inclined surface 30, rainwater can be drained to the vertical gutter 10 through the drain holes 28a and 28c. Therefore, even when the rainfall is large, the rainwater can be smoothly flowed from the horizontal gutter 19 to the vertical gutter 10. Since the water collector 27 has a water stop portion 29 that prevents rainwater from flowing out of the upper end of the vertical gutter 10, it is possible to prevent rainwater from leaking from the butting portion between the vertical gutter 10 and the horizontal gutter 19. Since the water collector 27 has a portion (bulging portion 31) that avoids the head of the bolt 15 that fixes the column-beam connecting fitting 14 to the column 1, the water collector 27 can be easily installed even if the head of the bolt 15 protrudes outside the column 1.
[0032] This structure (first and second embodiments) includes a ceiling 37. The ceiling 37 has fine irregularities 36 in which ridge portions 36a and valley portions 36b are repeatedly connected and continuously formed over the entire surface in one direction. The top of the ridge portion 36a is formed in an R shape. Since the irregularities 36 have a pitch P and a depth h at which dew condensation water droplets are held on the ceiling 37, diffuse reflection of light on the ceiling 37 is suppressed and a matte texture is obtained. Therefore, it becomes a high-class structure, and moreover, it is possible to prevent the dew condensation water droplets from falling from the ceiling 37. When the pitch P is 0 < P ≤ 1.5 mm and the depth h is 0 < h ≤ 0.5 mm, the irregularities 36 can obtain water droplet retention and a matte feeling, and also have good smoothness, safety, and cleanability. When the pitch P is 0.5 < P ≤ 1.0 mm and the depth h is 0.05 < h ≤ 0.1 mm, the irregularities 36 can obtain even better water droplet retention and a matte feeling. The ceiling 37 is made of aluminum material and has an anodized coating formed on its surface, so that it has corrosion resistance and decorativeness while retaining the fine irregularities 36. Furthermore, in this structure (first and second embodiments), the roof 3 is above the ceiling 37, so there is no need to install roof materials and ceiling materials separately, which simplifies the installation. The manufacturing method of this structure (first and second embodiments) is to use an extruded profile to form fine irregularities 36 on the underside of a ceiling material (roof material) 8, with peaks 36a and valleys 36b repeatedly connected in one direction, with the peaks of the peaks 36a being formed in an R-shape, and the irregularities 36 having a pitch P and depth h that allow condensation droplets to be retained on the ceiling 37, and by forming an anodized coating on the surface of the ceiling material 8 and arranging the ceiling materials 8 in a direction perpendicular to the extrusion direction to form the ceiling 37, diffuse reflection of light on the ceiling 37 is suppressed and a matte texture is obtained, resulting in a luxurious-looking ceiling 37 and also preventing condensation droplets from falling from the ceiling 37. This structure (first embodiment) 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), thereby improving the design while also preventing condensation water from dripping from the underside of the retaining frame 7. This structure (second embodiment) comprises a wall 38, on which fine irregularities 36 consisting of repeated connections between peaks 36a and valleys 36b are formed continuously in one direction over the entire surface, with the peaks of the peaks 36a being formed in an R-shape, and the irregularities 36 have a pitch P and depth h that allow condensation droplets to be retained on the wall 38, thereby suppressing diffuse reflection of light on the wall 38 and providing a matte texture, resulting in a luxurious-looking structure and preventing condensation droplets from falling from the wall 38.
[0033] The present invention is not limited to the above-described embodiment. The fine unevenness formed on the ceiling or wall only needs to have a pitch and depth that allows condensation water droplets to be retained, and the specific pitch and depth dimensions and cross-sectional shape are not particularly limited and can be changed as appropriate. The cross-sectional shape and material of the roof material and wall material can be changed as appropriate. The structure of the roof and wall is not important. The present invention is not limited to carports, and can be applied to any structure having a roof or wall, such as cycle ports, passage shelters, and terrace roofs. [Explanation of symbols]
