As shown in FIG. 6, the roof 6 is inclined by 4 ° with respect to the horizontal plane so that the front side (rain gutter 8 side) is low. As shown in FIG. 5, the plurality of rafters 1, 1, ... Are arranged along the slope 10 of the roof. Further, as shown in FIGS. 4 and 7, the plurality of rafters 1, 1, ... Are arranged in parallel on the beam 1 at the same height by the U-shaped mounting bracket 11.

As shown in FIG. 7, the roof 6 of this simple structure does not have a middle bone between the rafters 1 and 1, so that the panel 2 does not bend downward due to its own weight even if there is no middle bone. In addition, the rafters 1 and the panel retainer 3 have the following features.
As shown in FIGS. 1 and 2, the rafter 1 is made of an aluminum profile having a substantially rectangular cross section, and panel receiving portions 12 for receiving the ends of the panel 2 are formed on both left and right sides of the upper surface. The upper surface 12a of the panel receiving portion 12 is inclined diagonally upward so that the outside is higher. The inclination angle α of the panel receiving portion 12 is set to 3 °. A rubber lower tight material 13 is attached to the panel receiving portion 12, and the lower tight material 13 is in contact with the lower surface of the panel 2. Further, a pair of ridges 14 and 14 are provided at the center of the upper surface of the rafter 1 in the left-right direction.
The panel presser 3 is a substantially strip-shaped member made of an aluminum profile, and panel presser portions 15 for pressing the end portions of the panel 2 are formed on both left and right sides. Similar to the upper surface 12a of the panel receiving portion 12, the lower surface 15a of the panel holding portion 15 is inclined diagonally upward so that the outer surface is higher. The tilt angle β of the panel holding portion 15 is set to the same angle (3 °) as the tilt angle of the panel receiving portion 12. A rubber upper tight material 16 is attached to the panel holding portion 15, and the upper tight material 16 is in contact with the upper surface of the panel 2. Further, the panel retainer 3 has a screw fixing portion 17 and a pair of hanging pieces 18 and 18 at the center portion in the left-right direction. As shown in FIG. 1, the panel retainer 3 engages the pair of hanging pieces 18 and 18 with the outside of the pair of ridges 14 and 14 on the upper surface of the rafter 1, and inserts the screw 19 into the screw fastening portion 17 from above. It is mounted on the rafter 1 by being screwed into the groove between the pair of ridges 14, 14 on the upper surface of the rafter 1.

FIG. 3A shows a state before tightening the screw 19 for attaching the panel retainer 3, and FIG. 3B shows a state after tightening the screw 19. As the screw 19 is tightened, as shown in FIG. 3 (b), the screw fastening portion 17 of the panel retainer 3 is pushed down by the screw head, and accordingly, between the screw fastening portion 17 and the panel retainer portion 15. The connecting portion 20 of the panel is elastically deformed so as to bend upward from the vicinity of the base 20a on the screwed portion 17 side while maintaining the inclination of 3 ° of the panel pressing portion 15, and the panel pressing portion 15 is elastically deformed by the elastic force 21 of the panel 2. The end portion of the panel 2 is sandwiched and held from above and below by the panel receiving portion 12 on the upper surface of the hanging tree 1 and the panel pressing portion 15 on the lower surface of the panel presser 3. As described above, the panel receiving portion 12 of the rafter 1 and the panel pressing portion 15 of the panel retainer 3 are both inclined diagonally upward by 3 ° so that the outside is high, so that both ends of the panel 2 are obliquely upward. Is held in. By holding both ends diagonally upward, a force that bends upward between the rafters 1 and 1 acts on the panel 2. By canceling this upward bending force and the downward bending force due to its own weight, the panel 2 becomes substantially flat between the rafters 1 and 1 as shown in FIG.

Similar to the rafters 1, the panel receiving portion 12 is provided on the upper surface of the side frame 7 in an inclined manner, and the panel 2 is formed by the panel receiving portion 12 and the panel pressing portion 15 of the panel retainer 3 mounted on the side frame 7. The end of the rafter is sandwiched and held diagonally upward.

FIGS. 8-10 show another embodiment of the holding portion at the end of the panel 2 by the rafters 1 and the panel retainer 3. In this embodiment, as shown in FIG. 9, the lower surface 15a of the panel pressing portion 15 of the panel pressing 3 is horizontal. The rafters 1 are the same as those described above, and are inclined by 3 ° so that the upper surface 12a of the panel receiving portion 12 is higher on the outside.
In this case, as the screw 19 for attaching the panel retainer 3 is tightened, the connecting portion 20 between the screw fastening portion 17 and the panel retainer portion 15 bends upward from the vicinity of the base 20a as shown in FIG. 10 (b). In addition to the elastic deformation, the panel holding portion 15 also elastically deforms in the vicinity of the end portion 20b on the panel pressing portion 15 side of the connecting portion 20 so as to follow the inclination of the panel receiving portion 12. In this way, even if the panel holding portion 15 is not angled, the end portion of the panel 2 can be held diagonally upward by elastically deforming following the inclination of the panel receiving portion 12. The panel presser 3 of the present embodiment (the panel presser portion 15 is not tilted) can also be used for a conventional carport or the like.

As described above, in the present simple structure, the upper surface of the rafter 1 (in the present embodiment, the lower tight material 13 attached to the panel receiving portion 12) and the lower surface of the panel presser 3 (in the present embodiment, the panel pressing portion 15). By sandwiching and holding both ends of the panel 2 diagonally upward with the upper tight material 16) attached to the rafters 1, 1 the panel 2 bends downward due to its own weight even if there is no middle bone between the rafters 1 and 1. By eliminating the rafters, there are effects such as cost reduction, labor saving in construction, and improvement in design. In this simple structure, a plurality of rafters 1, 1, ... Arranged along the slope 10 of the roof are arranged at substantially the same height, and the panel 2 is attached between the rafters 1, 1 to form the panel 2. Even if the panel 2 swells upward between the rafters 1 and 1 by holding both ends of the roof diagonally upward, rainwater does not collect on the roof 6 and the rainwater is quickly drained along the slope 10 of the roof. can.
Furthermore, in this simple structure, the inclination angle of both ends of the panel is set so that the panel 2 is substantially flat between the rafters 1 and 1 in offset against the downward bending due to its own weight, so that the panel 2 Looks flat and has good design, and rainwater drainage is also good. The rafters 1, 1, ... Are arranged at substantially the same height, and by holding both ends of the panel 2 diagonally upward at substantially the same angle, the force for bending the panel 2 upward is evenly applied. As a result, the panel 2 becomes substantially flat between the rafters 1 and 1.

11 and 12 show a second embodiment of the simple structure of the present invention. This embodiment is applied to a carport for three passenger cars, and the length of the beam 5 and the width of the roof 6 are longer than those of the first embodiment. It is the same as the first embodiment that the roof 6 is inclined so that the front side is lowered.
In this embodiment, 13 rafters 1 are mounted on the beam 5, of which the three rafters 1a, 1a, 1a near the center in the left-right direction are on both sides of the mounting bracket 11 as shown in FIG. By increasing the length of the rising portions 22, 22, they are arranged at a position slightly higher than the other rafters 1b, 1b, .... The height difference h between the rafters 1a in the middle portion and the other rafters 1b is 8 mm. This is because the length of the beam 5 is long, so that the beam 5 bends downward due to its own weight and the weight of the roof 6, and in the actual installation state, the rafters 1a in the middle part are also other rafters. It is arranged at substantially the same height as 1b.
The rafters 1 (1a, 1b) and the panel presser 3 are the same as those in the first embodiment described above, and both ends of the panel 2 are diagonally upward at the upper surface of the rafter 1 and the lower surface of the panel presser 3. It is sandwiched and held, thereby preventing the panel 2 from bending downward due to its own weight even if there is no middle bone between the rafters 1 and 1.

13 and 14 show a third embodiment of the simple structure of the present invention. This simple structure is a carport for one passenger car, and the beam 5 is cantilevered and supported by one pillar 4. As shown in FIG. 13, the beam 5 is inclined upward by 1 ° from the base end portion to the tip end portion. This is in consideration of the fact that the beam 5 bends so that the tip side is lowered due to its own weight or the weight of the roof 6, and in the actual installation state, the beam 5 becomes substantially straight (horizontal) and is mounted on the beam 5. The plurality of rafters 1, 1, ... Are arranged at substantially the same height. Similar to the first and second embodiments, the roof 6 is inclined so that the front side is lowered (see FIG. 14).
The rafters 1 and the panel presser 3 are the same as those in the first embodiment described above, and both ends of the panel 2 are sandwiched and held diagonally upward by the upper surface of the rafter 1 and the lower surface of the panel presser 3. This prevents the panel 2 from bending downward due to its own weight even if there is no middle bone between the rafters 1 and 1.

The present invention is not limited to the embodiments described above. The specific shapes of the rafters and panel retainers can be changed as appropriate. In the simple structure of the present invention, it is sufficient that a plurality of rafters arranged along the slope of the roof are arranged at substantially the same height, and other configurations such as arrangement of columns and beams, configuration and orientation of the roof are required. Etc. are optional. The tilt angle of the panel receiving portion on the upper surface of the rafters can be appropriately set in consideration of the strength of the panel, the distance between the rafters, and the like. This simple structure can be applied not only to the carport shown in the embodiment but also to any simple structure, for example, a wall-mounted simple structure such as a terrace or a garden room.
