[0007] The embodiments of the present invention will be described below with reference to the drawings. Figures 1 to 5 show one embodiment of the structure of the present invention. This structure is applied to cycle ports installed in public facilities and the like for parking bicycles. Furthermore, this structure uses solar panels 7 as roofing material, and thus serves as both a cycle port and a solar power generation facility.

[0008] As shown in Figures 1 and 2, this structure comprises three columns 8, 8, 8 erected at intervals in the left-right direction, three beams (one of the members) 1, 1, 1 cantilevered to the upper ends of each column 8, 8, 8, and front and rear purlins (the other members) 2a, 2b installed on the beams 1, 1, 1 and intersecting with them, and a roof 9 supported by the front and rear purlins 2a, 2b. As shown in Figure 2, the roof 9 slopes downward toward the rear.

[0009] As shown in Figures 1, 3, and 4, the roof 9 is constructed by installing multiple rafters 10, 10, ... on the front and rear purlins 2a, 2b at regular intervals in the left-right direction, installing a front frame 11 on the front (upstream) ends of the multiple rafters 10, 10, ... and installing gutters 12 on the rear (downstream) ends of the multiple rafters 10, 10, ... and installing solar panels 7 between each rafter 10, 10, .... As shown in Figure 4, the solar panel 7 has a rectangular frame 13 and a solar cell panel 14 held inside the frame 13.

[0010] Column 8 is made of an aluminum profile with a roughly rectangular cross-section, and is erected vertically by embedding the lower part in the ground and securing the surrounding area with mortar. As shown in Figures 3 and 6, an L-shaped column-beam connecting fitting 15 is inserted into the upper end of column 8 and fixed with a bolt 16. The end of the upper end of column 8 is covered with a cap 17.

[0011] As shown in Figure 6, beam 1 is made of an aluminum profile with a roughly rectangular cross-section and is connected to column 8 by inserting a column-beam connecting fitting 15 into the hollow section and fixing it with bolts 16. As shown in Figure 3, beam 1 is inclined downwards toward the rear. The inclination angle α of beam 1 is 4°. The inclination angle β of roof 9 is slightly steeper at 5°.

[0012] As shown in Figures 3, 4, and 5, connecting fittings 3a and 3b are attached to the upper surface of beam 1 for connecting the front and rear joists 2a and 2b across beam 1. The connecting fittings 3a and 3b are formed in a U-shape by press-forming a single metal plate, and as shown in Figures 6 and 9, they have a mounting plate portion 19 that abuts against the upper surface of the beam 1 and is fixed with screws 18, a front wall 4 and a rear wall 5 that rise vertically upward from the front and rear edges of the mounting plate portion 19, and side walls 20, 20 that rise vertically upward from the left and right edges of the mounting plate portion 19. As shown in Figures 4 and 5, the front wall 4 and the rear wall 5 have upper edges that extend to the same height as the upper surfaces of the joists 2a and 2b. The front wall 4 and the rear wall 5 have four through holes 22 (see Figure 6) for screws 21 used to fix the joists 2a and 2b, spaced apart in the vertical and horizontal directions. The mounting plate portion 19 is inclined at the same angle (4°) as the beam 1, but the upper edges of the side walls 20, 20 are formed horizontally and serve as receiving portions 6 that support the lower surfaces of the joists 2a, 2b. As shown in Figure 5, the height h of the receiving portion 6 from the upper surface of the beam 1 is different for the front connecting fitting 3a and the rear connecting fitting 3b, with the height h of the receiving portion 6 from the upper surface of the beam 1 being higher for the front connecting fitting 3a. This makes the inclination angle β of the roof 9 steeper than the inclination angle α of the beam 1, allowing water to flow more easily over the roof 9.

[0013] As shown in Figure 5, the ceiling joists 2a and 2b are formed from aluminum profiles with a roughly rectangular cross-section. Two rows of grooves 24 are provided on the upper surfaces of the ceiling joists 2a and 2b to hold the backing plate 23 in a slidable manner in the longitudinal direction. The joists 2a and 2b are inserted from above between the front wall 4 and rear wall 5 of the connecting fittings 3a and 3b, and the lower surfaces of the joists 2a and 2b are temporarily placed on the receiving parts 6 of the connecting fittings 3a and 3b. The front wall 4 and rear wall 5 are then attached to the joists 2a and 2b by screwing them in with screws 21 from the front and rear. As shown in Figure 1, the ceiling joists 2a and 2b are formed by dividing them left and right at the central position in the left-right direction where the central column 8 is located. As shown in Figures 4 and 7, a cylindrical connecting member 25 is inserted into the hollow section, the end faces are butted together, and the connecting member 25 is fastened with screws 26 from above and below to connect them. As mentioned earlier, the front wall 4 and rear wall 5 of the connecting fittings 3a and 3b extend to the same height as the top surface of the ceiling joists 2a and 2b, so as shown in Figure 4, the joint 27 of the divided ceiling joists 2a and 2b is hidden by the front wall 4 and rear wall 5 of the connecting fittings 3a and 3b.

[0014] The purlin 10 is formed of an aluminum profile. As shown in Fig. 4, it has a horizontally long rectangular cross-section hollow portion 28 located at the lower part, a narrower hollow portion 29 located above it, a gutter portion 30 provided on the side of the hollow portion 29, a groove portion 31 located above the narrower hollow portion 29, and a mounting portion 32 provided with a lateral overhang at the upper end. The purlin 10 is attached by screwing a purlin mounting fitting 33 with an L-shaped cross-section to the side surface. The lower surface of the purlin mounting fitting 33 is placed on the upper surfaces of the eaves edges 2a, 2b. A bolt 34 inserted from above into the purlin mounting fitting 33 is screwed into and tightened on a back plate 23 previously held in a groove 24 on the upper surfaces of the eaves edges 2a, 2b, enabling the purlin 10 to be attached at an arbitrary position in the longitudinal direction of the eaves edges 2a, 2b.

[0015] As shown in Fig. 4, the solar panel 7 is placed straddling the mounting portions 32 of adjacent purlins 10, 10, and is attached by pressing down on the frame 13 from above with a panel retainer 35. The panel retainer 35 is attached by screwing a bolt 36 inserted from above into a back plate 37 held in the groove portion 31 of the purlin 10. Rainwater that has infiltrated between the left and right solar panels 7, 7 flows rearward through the gutter portion 30 of the purlin 10 as shown in Fig. 3, and flows into a gutter 12 installed at the rear ends of the purlins 10, 10,.... The rainwater that has entered the gutter 12 is drained to the ground through a downspout 38 provided along the column 8.

[0016] As shown in Fig. 3, a cross member 39 with a U-shaped cross-section whose upper side is open is installed at the front ends between the purlins 10, 10,.... Rainwater that has infiltrated between the front frame 11 and the solar panel 7 is received by the cross member 39 and flows from the cross member 39 to the gutter portion 30 of the purlin 10. In addition, an angle 40 is installed at the rear part between the purlins 10, 10,.... The light that shines in from between the solar panel 7 and the gutter 12 is blocked by the angle 40 so that no light leaks under the roof 9.

[0017] Next, the construction procedure for this structure will be explained. First, as shown in Figure 8-1(a), the columns 8, 8, 8 are erected vertically in their designated positions by embedding their lower parts into holes drilled in the ground. Next, as shown in Figure 8-1(b), beams 1, 1, 1 are connected to the top of each column 8, 8, 8 via column-beam connecting fittings 15. Then, as shown in Figure 6, connecting fittings 3a and 3b are attached to the upper surface of beam 1 at predetermined positions by screwing them in from above with screws 18. Next, as shown in Figure 8-2(c), the front and rear joists 2a and 2b are attached to the beams 1,1,1 in a crisscross pattern. The joists 2a and 2b are attached by inserting them from above between the front wall 4 and rear wall 5 of the connecting fittings 3a and 3b, as shown in Figure 7, and temporarily placing the lower surfaces of the joists 2a and 2b on the receiving parts 6 of the connecting fittings 3a and 3b. With the joists 2a and 2b temporarily placed via the connecting fittings 3a and 3b, the front wall 4 and rear wall 5 of the connecting fittings 3a and 3b are screwed to the joists 2a and 2b from the front and rear using screws 21 to fix the joists 2a and 2b in place. The process of connecting the joists 2a and 2b, which are formed by dividing them into left and right halves, via the connecting material 25 can also be done with the joists 2a and 2b temporarily placed on the connecting fittings 3a and 3b. In this way, the structure allows for easy installation of the long joists 2a and 2b by temporarily placing them on the beams 1, 1, 1 via connecting fittings 3a and 3b. Next, as shown in Figure 8-2(d), rafters 10, 10, ... are attached at predetermined intervals, straddling the front and rear joists 2a, 2b. Next, as shown in Figure 8-3(e), a crossbar 39 is installed at the front end between the rafters 10, 10, ... and an angle 40 is installed at the rear between the rafters 10, 10, .... Next, as shown in Figure 8-3(f), the front frame 11 is erected on the front ends of the rafters 10, 10, ... Next, as shown in Figure 8-4(g), gutters 12 are installed on the rear ends of the rafters 10, 10, ... Next, as shown in Figure 8-4(h), a downpipe 38 is installed from the gutter 12 to the column 8. Next, as shown in Figure 8-5(i), the solar panels 7,7,... are placed between the rafters 10,10,... and the panel retainers 35 are attached to fix the solar panels 7,7,... to the rafters 10,10,.... The solar panels 7,7,... are installed sequentially from one side to the other in the left-right direction. Finally, as shown in Figure 8-5(j), panel retainers 42 are attached to the front frame 11 to hold down the front ends of the solar panels 7, 7, ...

[0018] As described above, this structure comprises one member (beam) 1, the other members (furring strips) 2a, 2b, and connecting fittings 3a, 3b. One member 1 is inclined downwards in the front-rear direction. The connecting fittings 3a, 3b are U-shaped with opposing pieces (front wall 4, rear wall 5) in the front-rear direction and a receiving portion 6 between the opposing pieces 4, 5, and are attached to the upper surface of one member 1. The other members 2a, 2b are placed on the receiving portion 6 of the connecting fittings 3a, 3b and positioned on one member 1, intersecting with it (see Figures 3, 4, 5). This makes it easy to position and connect the other members 2a, 2b on the inclined one member 1, improving constructability. Since the connecting fittings 3a and 3b are made by bending a single plate to form opposing pieces 4 and 5 and a receiving part 6 (see Figures 6 and 9), they can be manufactured at low cost. This structure has one connecting fitting 3a and another connecting fitting 3b, and by making the height h from the upper surface of one of the members 1 of the receiving part 6 different between the one connecting fitting 3a and the other connecting fitting 3b (see Figure 5), it is possible to make the inclination angle α of one of the members 1 and the inclination angle β of the roof 9 different. For example, the inclination angle β of the roof 9 can be made steeper than the inclination angle α of one of the members 1 to make it easier for water to flow over the roof 9.

[0019] The present invention is not limited to the embodiments described above. The combination of one member and the other member is arbitrary and is not limited to beams and joists; for example, it may be a girder (one member) and a beam (the other member), etc. The material and cross-sectional shape of one member and the other member can be changed as appropriate. One member may be inclined downwards toward the front. The shape and material of the connecting fittings can be changed as appropriate. The present invention is not limited to cycle ports, but can be applied to any structure having one member and the other member that intersect and are connected to each other, such as carports and walkway shelters.
