[0007] The embodiments of the present invention will be described below with reference to the drawings. Figures 1 to 13 show one embodiment of the structure of the present invention. This structure is applied to a carport for one passenger car installed on the premises of a house. As shown in Figures 1-5, this structure comprises two columns 1,1 erected on the left side when viewed from the front, spaced apart in the front-to-back direction, two beams 2,2 supported at the upper ends of each column 1,1, and a roof 3 supported by the beams 2,2. As shown in Figure 3, the roof 3 slopes so that the left side, where the columns 1 are located, is lower when viewed from the front.

[0008] In the following explanation, when viewed from the upstream side of roof 3, the side closer to the viewer will be referred to as the front side, the side further away as the rear side, the left side as one side, and the right side as the other side. Also, when viewed from above, the direction along the roof slope will be referred to as the front-to-back direction, and the direction perpendicular to the roof slope will be referred to as the left-to-right direction.

[0009] Column 1 is made of an extruded aluminum alloy profile and, as shown in Figure 8, is formed in a hollow shape with a roughly rectangular cross-section. The front faces 1a and 1b on one and the other sides of Column 1 protrude further back than the rear front face 1c, and by fitting and attaching a gutter 9 between these edges, a downpipe 10 for draining rainwater from the roof 3 to the ground is integrally formed with Column 1. As shown in Figure 3, column 1 is inserted at its lower end into a foundation hole 11 formed in the ground, and the area around column 1 is reinforced with concrete 12. In order to install this structure near the adjacent property boundary 13, the foundation hole 11 is provided right next to the adjacent property boundary 13, and column 1 is positioned eccentrically toward the adjacent property boundary 13. A predetermined distance A (specifically about 80 mm) is provided between column 1 and the foundation hole 11. As shown in Figure 6, an L-shaped column-beam connector 14 is inserted into the hollow section at the top of column 1 and secured with bolts 19.

[0010] Beam 2 is formed from an extruded aluminum alloy profile and, as shown in Figure 10, is a hollow profile with a roughly rectangular cross-section, where the vertical dimension is larger than the horizontal dimension. A groove 15 is formed on the lower surface of beam 2 along its longitudinal direction, and the beam lower cover 16 is attached by engaging with this groove 15. The beam lower cover 16 protrudes from the left and right sides of beam 2 on both sides. Roof material receivers 17 are attached to both left and right side surfaces of the beam 2. The roof material receiver 17 is formed as an extruded profile of aluminum alloy to have a substantially L-shaped cross-section, and has projecting portions 18 that project toward one side and the other side, respectively. As shown in Fig. 6, the beam 2 is connected to the column 1 by inserting the column-beam connector 14 into the hollow portion and fixing the connector with a bolt 19. The lower end (rear end) of the beam 2 protrudes rearward beyond the column 1.

[0011] As shown in Fig. 5, the roof 3 comprises a roof frame 20 formed by framing a front girder 5, a gutter girder 7, and left and right side frames 6, 6 into a rectangular shape, and a plurality of roof materials 4, 4, ... that are arranged inside the roof frame 20 in the front-rear direction and mounted side by side in the left-right direction. As shown in Fig. 6, the front girder located on the water upper side is fixedly attached to the water upper side ends of the front and rear beams 2, 2 using L-shaped metal fittings 21. The front girder 5 is formed of an extruded aluminum alloy profile, and has a substantially right-angled triangular cross-section whose upper surface is inclined downward toward the outer peripheral side of the roof. The front girder 5 has a roof material receiving portion 22 for receiving the lower surface of the roof material 4 at the lower end of the inner peripheral side surface, and a mounting portion 24 on which a mounting bracket 23 of the roof material 4 is placed and screwed is formed at the upper part of the inner peripheral side surface.

[0012] As shown in Fig. 9, the side frames 6 on one side and the other side are each formed of an aluminum profile having a substantially right-angled triangular cross-section that is substantially the same as that of the front girder 5. For the side frame 6 on one side, a plate-shaped projecting portion 25 is provided to project toward the other side at an intermediate vertical position of the inner peripheral side surface, and a groove 26 having a substantially C-shaped cross-section is formed at the lower part of the inner peripheral side surface. The side frame 6 on the other side has a cross-sectional shape that is symmetrical to that of the side frame 6 on one side.

[0013] As shown in Fig. 11, both longitudinal end portions 5a of the front girder 5 are cut at an oblique angle of 45° with respect to the longitudinal direction, and the longitudinal end portion 6a on the front girder 5 side of each of the side frames 6 on one side and the other side is cut at an oblique angle of 45° with respect to the longitudinal direction. The front girder 5 and the side frame 6 are connected by an L-shaped metal fitting 27 on the inner peripheral side in a state where the obliquely cut longitudinal end portions 5a and 6a are butted against each other. A plate-shaped cap 28 made of resin is interposed between the longitudinal end portion 5a of the front girder 5 and the longitudinal end portion 6a of the side frame 6.

[0014] As described above, in the present structure, the longitudinal ends 5a and 6a of the front girder 5 and the side frame 6 are cut at an oblique angle of 45°, and the obliquely cut longitudinal ends 5a and 6a are butted against each other and connected. This eliminates the need to individually close the end faces of the front girder 5 and the side frame 6, thereby simplifying the construction of the roof frame 20 and providing good constructability. In addition, in the present structure, the cross-sectional shapes of the front girder 5 and the side frame 6 are formed into a substantially right-angled triangular cross-section whose upper surface is inclined downward toward the outer peripheral side of the roof. This allows the roof 3 to appear thinner when viewed from the surroundings, providing good designability (see FIG. 1).

[0015] As shown in FIG. 6, the gutter girder 7 located on the lower eave side is fixedly attached to the lower eave side ends of the front and rear beams 2, 2 with L-shaped metal fittings 29. The gutter girder 7 is formed of an extruded aluminum alloy profile, and comprises a main body portion 30 having a substantially rectangular cross-section connected to the beam 2 via the metal fitting 29, a gutter 31 attached by screwing to the lower part of the outer peripheral side surface of the main body portion 30, and a gutter girder cover 8 attached to the outer peripheral side surface of the main body portion 30. In the main body portion 30, a mounting portion 24 on which a roof material mounting fitting 23 is placed and screwed is formed on the upper part of the inner peripheral side surface. In the column 1, the upper end portion of the portion projecting from the rear facing surface 1c on the depth surfaces 1a and 1b on one side and the other side is notched. The gutter 31 is fitted into this notch 32, and the inner peripheral side surface thereof is in contact with the rear facing surface 1c of the column 1. Therefore, the entire gutter girder 7 including the main body portion 30 and the gutter 31 is located on the rear side of the rear facing surface 1c of the column 1. Since the entire gutter girder 7 is located on the rear side of the rear facing surface 1c of the column 1 as described above, the projection dimension B (see FIG. 3) of the roof 3 protruding from the column 1 is increased. Specifically, the projection dimension B of the roof 3 protruding from the column 1 is substantially equal to or larger than the predetermined dimension A between the column 1 and the foundation hole 11. As shown in Figure 6, the gutter 31 has a roof material receiving portion 33 at the upper part of its inner circumference that receives the lower surface of the downstream end of the roof material 4. Rainwater that flows down the upper surface of the roof material 4 falls into the gutter 31 through the gap between the roof material receiving portion 33 and the main body portion 30. The gutter 31 also has a drainage hole 34 formed in the part that is fitted into the notch 32 of the column 1. Rainwater that enters the gutter 31 flows from the drainage hole 34 to the downpipe 10 located on the rear side of the column 1, and is drained to the ground through a drainage opening 35 (see Figure 3) that is provided at the lower end of the downpipe 10 and opens outwards. The gutter gutter cover 8 is screwed to the main body 30 from above with screws 36, covering the outer periphery of the main body 30 and concealing the attachment point of the gutter 31 to the main body 30.

[0016] As shown in Figures 12 and 13, the gutter beam 7 has its longitudinal end 7a cut straight, and the gutter beam 7 and the side frame 6 are connected by an L-shaped fitting 37 on the inner side, with the longitudinal end 7a of the gutter beam 7 in contact with the inner side surface of the side frame 6. A resin plate-shaped cap 38 is attached to the rear end of the side frame 6, and the cap 38 closes the end of the side frame 6. The gutter cover 8, which is attached to the outer perimeter side of the gutter gutter 7, has its longitudinal end protruding beyond the gutter gutter 7 and overlapping with the rear side of the cap 38, covering the end of the side frame 6. The end 8a of the longitudinal end of the gutter cover 8 is hidden by the end cover 39 provided on the cap 38.

[0017] In this structure, the longitudinal end 7a of the gutter beam 7 is fixed in contact with the inner surface of the side frame 6, and the gutter beam cover 8 is attached to the outer surface of the gutter beam 7. By covering the end of the side frame 6 with the gutter beam cover 8, the construction of the roof frame 20 can be simplified, resulting in good workability. Moreover, the end of the side frame 6 and the outer surface of the gutter beam 7 are continuously covered by the gutter beam cover 8, resulting in good aesthetics. Furthermore, since this structure has a cap 38 that conceals the end 8a at the longitudinal end of the gutter girder cover 8, its aesthetic appeal is further enhanced.

[0018] As shown in Figures 5, 6, and 7, the roofing material 4 is stretched between the front beam 5 and the gutter beam 7, and multiple pieces are installed side by side between one side frame 6 and the beam 2, between beams 2 and 2, and between beam 2 and the other side frame 6. Each roofing material 4 is made from an extruded aluminum alloy and, as shown in Figures 7, 9, and 10, is a plate-like member without a hollow section. As shown in Figure 6, each roofing material 4 has mounting brackets 23 attached to its upstream (front) end and downstream (rear) end. The upstream mounting bracket 23 is placed on the mounting portion 24 of the front beam 5 and screwed in, and the downstream mounting bracket 23 is placed on the mounting portion 24 of the gutter beam 7 and screwed in. The downstream end of the roofing material 4 extends behind the rear visible surface 1c of the column 1 and is incorporated into the gutter beam 7, so that rainwater flowing down the upper surface of the roofing material 4 falls into the gutter 31 of the gutter beam 7. As will be described later, the roofing material 4 is installed sequentially from one end towards the other, with its side edges connected to one another.

[0019] As shown in Figures 6 and 7, the roofing material 4, the front beam 5, the side frame 6, and the underside of the beam 2 (beam under cover 16) are almost flush with each other. The beam under cover 16 has the same width as the roofing material 4. As a result, the underside of the roof 3 is formed flat, and when the roof 3 is viewed from below, the front beam 5 and side frame 6 are not noticeable, and the beam under cover 16 is indistinguishable from the roofing material 4, resulting in a very clean design (see Figure 2). Furthermore, in this structure, the roofing material 4, the front beam 5, the side frame 6, and the underside of the beam 2 are almost flush with each other. As shown in Figure 3, when viewed from one side or the other, approximately the lower half of the beam 2 is hidden by the side frame 6 of the roof 3. Therefore, compared to conventional carports where the roof is placed on top of the beam or suspended below the beam, the beam 2 is less conspicuous, resulting in an unprecedentedly simple and sharp appearance.

[0020] As shown in Figures 7, 9, and 10, there are three types of roofing materials 4: end roofing materials 4a, which are placed at one end; beam side roofing materials 4b, which are placed adjacent to one side of beam 2; and other roofing materials (hereafter referred to as intermediate roofing materials) 4c.

[0021] As shown in Figure 9, the end roofing material 4a has a flat plate-shaped flat section 40, a rising section 41 that extends upward from the flat section on one side, a projection 42 that protrudes to one side from the upper end of the rising section 41, a rising section 43 that extends upward from the flat section 40 on the other side, and a projection 44 that protrudes to the other side from the upper end of the rising section 43. The edge 45 on one side of the flat section is formed in a shape that is slightly raised from the flat section 40 and then curved toward one side, and a ridge 47 is formed on the other side edge 46 of the flat section 40. The edge 45 on one side of the flat section 40 is located to one side of the projection 42 on one side. The edge 46 on the other side of the flat section 40 is located to the other side of the projection 44 on the other side. The end roofing material 4a has one protruding portion 42 overlapping the protruding portion 25 of the side frame 6 and is secured with screws 48 from above. One side edge 45 of the end roofing material 4a is fitted into the groove 26 of the side frame 6. As a result, a roughly rectangular hollow section 49 is formed below the connection between the side frame 6 and the end roofing material 4a. The bottom surface of the side frame 6 and the bottom surface of the end roofing material 4a are on the same plane.

[0022] As shown in Figure 9, the intermediate roofing material 4c has a flat plate-shaped flat section 40, a rising section 41 that extends upward from the flat section 40 on one side, a projection 42 that protrudes to one side from the upper end of the rising section 41, a rising section 43 that extends upward from the flat section 40 on the other side, and a projection 44 that protrudes to the other side from the upper end of the rising section 43. A hanging piece 50 is provided at the tip of the projection 42 on one side. The edge 45 on one side of the flat section 40 is formed in a shape that rises slightly from the flat section 40 and then curves toward one side, and a ridge 47 is formed on the other side edge 46 of the flat section 40. The edge 45 on one side of the flat section 40 is located on the other side of the projection 44 on the other side of the adjacent roofing material (end roofing material 4a or intermediate roofing material 4c). The edge 46 on the other side of the flat section is located on the other side of the projection 44 on the other side. The intermediate roofing material 4c has one protruding portion 42 overlapping the other protruding portion 44 of the adjacent roofing material 4a, 4c from above, and is fastened with screws 48 from above. The one-sided edge 45 of the intermediate roofing material 4c and the other-sided edge 46 of the adjacent roofing material 4a, 4c are in contact with or close to each other at a position on the other side of the other protruding portion 44 of the adjacent roofing material 4a, 4c. As a result, a roughly rectangular hollow portion 51 is formed below the connecting portion between the adjacent roofing materials 4a, 4c. The flat portion 40 of the intermediate roofing material 4c and the flat portion 40 of the adjacent roofing material 4a, 4c are on the same plane. As shown in Figure 10, the intermediate roofing material 4c is also attached to a position adjacent to the other side of the beam 2. In this case, the protruding portion 42 on one side of the intermediate roofing material 4c is overlapped and screwed onto the protruding portion 18 on the other side of the beam 2, and the edge portion 45 on one side of the intermediate roofing material 4c is located on the other side of the protruding portion 18 on the other side of the beam 2, and is in contact with or close to the projection 47 on the other side edge portion 54 of the beam lower cover 16. As a result, a hollow portion 53 with a roughly rectangular cross-section is formed below the connection between the intermediate roofing material 4c and the beam 2. The lower surface of the intermediate roofing material 4c and the lower surface of the beam lower cover 16 are on the same plane.

[0023] As shown in Figure 10, the roofing material 4b on one side of the beam has a flat plate-shaped flat section 40, a rising section 41 that extends upward from the flat section 40 on one side, a projection 42 that protrudes to one side from the upper end of the rising section 41, a rising section 43 that extends upward from the flat section 40 on the other side, and a projection 44 that protrudes to the other side from the upper end of the rising section 43. Hanging pieces 50 are provided at the tips of the projections 42 and 44 on one and the other side. The edge 45 on one side of the flat section 40 is formed in a shape that rises slightly from the flat section 40 and then curves toward one side, and the edge 46 on the other side of the flat section 40 is formed in a shape that rises slightly from the flat section 40 and then curves toward the other side. The edge 45 on one side of the flat section 40 is located on the other side of the projection 44 on the other side of the adjacent roofing material 4c. The other side edge 46 of the flat plate portion 40 is located on one side of the protruding portion 18 of the beam 2. The roofing material 4b on one side of the beam has one side projection 42 overlapping the other side projection 44 of the adjacent roofing material 4c from above, and the other side projection 44 overlapping the projection 18 of the roofing material support 17 attached to the side of the beam 2 from above, and is fastened with screws 48 from above. The one side edge 45 of the roofing material 4b on one side of the beam and the other side edge 46 of the adjacent roofing material 4c are in contact with or close to each other at a position on the other side of the projection 44 of the adjacent roofing material 4c, thereby forming a roughly rectangular hollow section 51 below the connection between the adjacent roofing materials 4b and 4c. In addition, the other side edge 46 of the roofing material 4b on one side of the beam and the one side edge 52 of the lower beam cover 16 are in contact with or close to each other at a position on the one side of the projection 18 of the beam 2, thereby forming a roughly rectangular hollow section 53 below the connection between the roofing material 4b on one side of the beam and the beam 2. The underside of the roofing material 4b on one side of the beam and the underside of the beam cover 16 are on the same plane.

[0024] Next, the construction procedure for this structure will be explained. First, as shown in Figure 14-1(a), two columns 1,1 are erected in their designated positions on the ground. Next, as shown in Figure 14-1(b), a column-beam connector 14 is attached to the upper end of each column 1,1. Next, as shown in Figure 14-1(c), beams 2, 2 are connected to the upper ends of each column 1, 1 using column-beam connectors 14. Next, as shown in Figure 14-2(d), the front girder 5 is erected between the front ends of beams 2, 2, and the gutter girder 7 is erected between the rear ends of beams 2, 2. After that, the side frames 6 are attached between the longitudinal ends of the front girder 5 and the gutter girder 7.

[0025] Next, the roofing material 4 is sequentially attached to the front beam 5 and the gutter beam 7, starting from one end in the longitudinal direction and moving toward the other end. First, as shown in Figure 15-1(a), the end roofing material 4a is placed on the other side of the side frame 6, and the protruding portion 42 on one side of the end roofing material 4a is aligned with the protruding portion 25 of the side frame 6 and fixed from above with screws 48. Because a hollow section 49 is formed below the connection between the side frame 6 and the end roofing material 4a, even if rainwater were to seep in from the connection between the side frame 6 and the end roofing material 4a, the seeping rainwater would be caught by the lower wall of the hollow section 49 and flow into the gutter 31 (see Figure 6), thus preventing rainwater from leaking between the side frame 6 and the end roofing material 4a or between the roofing material 4a and the gutter beam 7. Next, as shown in Figure 15-1(b), with the projection 42 on one side of the intermediate roofing material (other side roofing material) 4c overlapping the projection 44 on the other side of the previously installed end roofing material (one side roofing material) 4a, the intermediate roofing material 4c is placed from above between the front beam 5 and the gutter beam 7, and the upstream and downstream ends are fixed to the front beam 5 and the gutter beam 7 respectively with mounting brackets 23 (see Figure 6). The projection 42 on one side of the intermediate roofing material 4c is then placed on top of the projection 44 on the other side of the end roofing material 4a from above and fixed with screws 48 from above. The edge 45 on one side of the intermediate roofing material 4c rests on the projection 47 on the other side edge 46 of the end roofing material 4a. Because one side edge 45 of the intermediate roofing material 4c is located on the other side of the other side projection 44 of the end roofing material 4a, when installing the intermediate roofing material 4c, the one side edge 45 does not interfere with the other side projection 44 of the previously installed roofing material 4a without having to tilt or rotate the intermediate roofing material 4c, and the intermediate roofing material 4c can be installed by lowering it straight down, resulting in good workability. In addition, because the intermediate roofing material 4c has a hanging piece 50 at the tip of the projection 42 on one side, rainwater is less likely to penetrate the joint between the roofing materials 4a and 4c. Even if rainwater does penetrate, a hollow section 51 is formed below the joint between the roofing materials 4a and 4c, so the penetrated rainwater is caught by the lower wall of the hollow section 51 and flows to the gutter 31 (see Figure 6), so rainwater does not leak between the roofing materials 4a and 4c or between the roofing materials 4a and 4c and the gutter beam 7. Subsequently, as shown in Figure 15-1(c), another intermediate roofing material 4c is attached to the other side of the intermediate roofing material 4c in the same manner.

[0026] The intermediate roofing materials 4c are installed in order, and when the installation reaches the front of one side of the beam 2, as shown in Figure 15-2(d), the beam side roofing material 4b is placed from above between the intermediate roofing material 4c and the beam 2. The protruding portion 42 on one side of the beam side roofing material 4b is placed on the protruding portion 44 on the other side of the previously installed intermediate roofing material 4c, and the protruding portion 44 on the other side of the beam side roofing material 4b is placed on the protruding portion 18 of the beam 2, and these are fixed with screws 48 from above. The one side edge 45 of the beam side roofing material 4b is placed on the projection 47 of the other side edge 46 of the previously installed intermediate roofing material 4c, and the other side edge 46 of the beam side roofing material 4c is placed on the projection 47 of the one side edge 52 of the beam lower cover 16. The roofing material 4b on one side of the beam, like the intermediate roofing material 4c, can be installed by lowering it straight down without tilting or rotating it, as the edge 45 on one side does not interfere with the protruding part 44 on the other side of the previously installed roofing material 4c, and the edge 46 on the other side does not interfere with the protruding part 18 of the beam 2. This makes installation easy. Furthermore, because the protruding portions 42 and 44 of the roofing material 4b on one side of the beam have hanging pieces 50 at their tips, rainwater is less likely to penetrate the connection between the intermediate roofing material 4c and the roofing material 4b on one side of the beam, and between the roofing material 4b on one side of the beam and the beam 2. Even if rainwater does penetrate, hollow sections 51 and 53 are formed below the connection between the roofing materials 4b and 4c, and below the connection between the roofing material 4b and the beam 2. As a result, the penetrated rainwater is caught by the lower walls of the hollow sections 51 and 53 and flows into the gutter 31 (see Figure 6), preventing rainwater from leaking between the roofing materials 4b and 4c, between the roofing material 4b and the beam 2, and between the roofing materials 4b and 4c and the gutter gutter 7.

[0027] Next, as shown in Figure 15-2(e), the intermediate roofing material 4c is placed on the other side of the beam 2 from above, and the protruding portion 42 on one side is overlapped with the 18 of the beam 2 from above and secured with screws 48 from above. The edge 45 on one side of the intermediate roofing material 4c rests on the projection 47 of the other side edge 54 of the beam lower cover 16. Because one side edge 45 of the intermediate roofing material 4c is located on the other side of the protruding part 18 of the beam 2, the one side edge 45 does not interfere with the protruding part 18 of the beam 2 without tilting or rotating the intermediate roofing material 4c, and the intermediate roofing material 4c can be installed by lowering it straight down, resulting in good workability. Then, as shown in Figure 15-2(f), another intermediate roofing material 4c is attached to the other side of the intermediate roofing material 4c in the same manner.

[0028] Subsequently, the intermediate roofing material 4c is installed sequentially in the same manner, and when it reaches the front of the beam 2 on the other side, the beam-side roofing material 4b is installed between the intermediate roofing material 4c and the beam 2, as shown in Figure 15-2(d). Next, the intermediate roofing material 4c is sequentially attached to the other side of the beam 2 on the other side. Once all the roofing material 4 is attached, the gutter cover 8 is attached to the outer side of the gutter gutter 7.

[0029] As described above, the roof 3 of this structure is constructed by attaching aluminum extruded roofing materials 4,4,... from one end of the front beam 5 and the gutter beam 7 in the longitudinal direction to the other, connecting their side edges to each other, and also connecting the side edges of the roofing materials 4 adjacent to the beam 2 to the beam 2. Therefore, there is no need to assemble a frame to form the roof framework as in conventional methods, resulting in improved workability. Moreover, each roofing material 4 can be attached by lowering it straight down between the front beam 5 and the gutter beam 7 without tilting or rotating it, further improving workability. Furthermore, the roof 3 of this structure is lightweight because each roofing material 4 is flat and does not have a hollow section. Hollow sections 49, 51, and 53 are formed below the connection points between the roofing materials 4, below the connection points between the side frame 6 and the roofing materials 4, and below the connection points between the roofing materials 4 and the beams 2, respectively, so that it can be lightweight while having sufficient strength. Moreover, the lower walls of the hollow sections 49, 51, and 53 can catch rainwater that seeps in from between the roofing materials 4 and direct it to the gutter 31 (see Figure 6), so it also has excellent watertightness.

[0030] As described above, this structure comprises a roofing material on one side (end roofing material) 4a and a roofing material on the other side (intermediate roofing material) 4c. The roofing material on one side 4a has a flat plate portion 40, a rising portion 43 that extends upward from the flat plate portion 40 on the other side, and a projection portion 44 that protrudes from the upper end of the rising portion 43 on the other side. The roofing material on the other side 4c has a flat plate portion 40, a rising portion 41 that extends upward from the flat plate portion 40 on one side, and a projection portion 42 that protrudes from the upper end of the rising portion 41 on the one side. The projection portion 42 of the roofing material on the other side 4c is superimposed on the projection portion 44 of the roofing material on one side 4a from above and screwed in place. Because the flat plate portion 40 of the roofing material on one side 4a and the flat plate portion 40 of the roofing material on the other side 4c are on the same plane (see Figure 15-1), the construction of the roof 3 can be easily carried out, resulting in good workability and good design. In this structure, the other side edge 46 of one side roofing material 4a and the one side edge 45 of the other side roofing material 4c are in contact with or close to each other at a position on the other side of the protruding portion 44 of one side roofing material 4a. As a result, when installing the other side roofing material 4c, it can be installed by lowering it straight down without tilting or rotating it, thus improving workability. Furthermore, it prevents rainwater from falling between the roofing materials 4a and 4c, thus improving watertightness. Furthermore, this structure comprises a side frame 6 and a roofing material (end roofing material) 4a located on the other side of the side frame 6. The side frame 6 has a projection 25 that protrudes to the other side, and the roofing material 4a has a flat plate portion 40, a rising portion 41 that rises from the flat plate portion 40 on one side, and a projection 42 that protrudes to the other side from the upper end of the rising portion 41. The projection 42 of the roofing material 4a is overlapped with the projection 25 of the side frame 6 and screwed in place. Since the lower surface of the side frame 6 and the lower surface of the roofing material 4a are on the same plane (see Figure 15-1), the roof 3 can be easily constructed, resulting in good constructability and aesthetic appeal. Furthermore, this structure comprises a roofing material (roofing material on one side of the beam) 4b and a beam 2 located on the other side of the roofing material 4b. The roofing material 4b has a flat plate portion 40, a rising portion 43 extending upward from the flat plate portion 40 on the other side, and a projection 44 extending outwards from the upper end of the rising portion 43. The beam 2 has a projection 18 extending outwards on one side. The projection 44 of the roofing material 4b is superimposed on the projection 18 of the beam 2 from above and screwed in place. Since the lower surface of the roofing material 4b and the lower surface of the beam 2 are on the same plane (see Figure 15-2), the roof 3 can be easily constructed, resulting in good constructability and aesthetic appeal.

[0031] Furthermore, this structure comprises a front beam 5, left and right side frames 6, 6, roofing materials 4, 4, ... installed side by side between the left and right side frames 6, 6, and a beam 2 supported by a column 1. The front beam 5 has its longitudinal end 5a cut at an angle, and the side frames 6 have their longitudinal end 6a on the front beam 5 side cut at an angle. The diagonally cut longitudinal ends 5a, 6a of the front beam 5 and the side frames 6 are connected to each other. As the undersides of the front beam 5, side frames 6, 6, roofing materials 4, 4, ... and beam 2 are almost on the same plane (see Figures 7 and 11), the construction of the roof 3 can be easily carried out, resulting in good constructability and good design aesthetics. The front beam 5 and side frame 6 have a roughly right-angled triangular cross-section with their upper surfaces sloping downward toward the outer perimeter of the roof 3, which makes the roof 3 appear thinner.

[0032] Furthermore, this structure comprises a gutter beam 7, left and right side frames 6, 6, and roofing materials 4, 4, ... installed side by side between the left and right side frames 6, 6. The gutter beam 7 is fixed by abutting its longitudinal end 7a against the inner circumferential surface of the side frame 6, and the roofing materials 4, 4, ... have their ends on the gutter beam 7 side embedded in the gutter beam 7. A gutter beam cover 8 is attached to the outer circumferential surface of the gutter beam 7, and the longitudinal end of the gutter beam cover 8 protrudes beyond the gutter beam 7 to cover the end of the side frame 6 (see Figures 6, 12, 13). As a result, the construction of the roof 3 is made easy, resulting in good workability and aesthetic appeal. Furthermore, since this structure has a cap 38 that conceals the end 8a at the longitudinal end of the gutter girder cover 8, its aesthetic appeal is further enhanced.

[0033] Furthermore, in this structure, the gutter girder 7 located on the downstream side, including the main body 30 and the gutter 31, is positioned behind the rear visible surface 1c of the column 1 (see Figure 6). The projection dimension B of the roof 3 from the column 1 is approximately the same as or greater than the predetermined dimension A between the column 1 and the foundation hole 11 (see Figure 3). Therefore, when installing near the property boundary 13, the roof 3 can be easily extended to the very edge of the property boundary 13, resulting in good workability. Furthermore, in this structure, the gutter girder 7 located on the downstream side, including the main body 30 and the gutter 31, is positioned behind the rear surface 1c of the column 1. This allows rainwater to be easily drained to the rear of the column 1 by directing it straight down from the gutter 31 through the downpipe 10 installed at the rear of the column 1 (see Figure 6), thus simplifying construction. With this structure, the ground area in front of the column 1 does not get wet with rainwater, and the downpipe 10 does not get in the way of vehicles entering and exiting.

[0034] The present invention is not limited to the embodiments described above. The materials and cross-sectional shapes of the roofing material, front girders, side frames, and beams can be changed as appropriate. The beams may be connected to columns at both ends in the longitudinal direction. The roof may be sloped such that the front or rear side is lower when the structure is viewed from the front. The present invention is not limited to carports, but can be applied to any structure having a roof, such as cycle ports, walkway shelters, and terrace roofs. [Explanation of Symbols]
