The bottom rafter 4 is connected to the beams 10 b and 10 c by a connecting material 29. A round pipe-shaped cross member 30 is attached to the front portion between the upper rafter 3 and the lower rafter 4, and connects the upper rafter 3 and the lower rafter 4.

  As shown in FIG. 6, the bottom rafter 4a located at the left and right ends of the roof 1 is formed of a U-shaped cross-section with an open top, and the bottom rafter 4a is formed as shown in FIG. It also serves as a rain gutter for flowing rain water contained in the rain gutter 26a provided in the rear frame 26 of the rear end portion of the roof 1 to the vertical gutter 31 provided in the front pillars 14a and 14b. Yes.

As shown in FIGS. 8, 9, and 10, the front and rear beams 10a, 10b, and 10c have the same cross-sectional shape, and have a one-side attachment portion 12 on the front side of the upper surface, and on the rear side of the upper surface. It has the other side attachment part 13, and has the groove | channel 32 between both attachment parts. As shown in FIG. 10, the other side attachment portion 13 is located slightly higher than the one side attachment portion 12. As shown in FIGS. 3, 8 and 10 (a), the upper rafter 3 from the left and right ends of the roof 1 is connected to the beams 10 a, 10 b, and 10 c on the one side by the connecting materials 11 a, 11 b, and 11 c. As shown in FIGS. 3, 9 and 10 (b), the upper rafter 3 on the inner side of the fourth from the left and right ends of the roof 1 is connected to the beams 10 a, 10 b, and 10 c as shown in FIGS. 11 a, 11 b, 11 c are attached to the other side attachment portion 13.
The connecting members 11a, 11b, and 11c provided at the beam ends described above and the connecting members 11a, 11b, and 11c provided at the intermediate portion of the beam are the same. Further, the intermediate beam 10b is provided at a position lower than the front and rear beams 10a and 10c, and the connecting material 11a for the front beam 10a and the connecting material 11b for the intermediate beam 10b are the same. Therefore, two types of connecting materials 11a, 11b, and 11c may be manufactured.

In this way, the other side attachment portion 13 is higher than the one side attachment portion 12, and the connecting members 11a, 11b, 11c are attached to the one side attachment portion 12 at the longitudinal ends of the beams 10a, 10b, 10c.

Since the central part in the left and right direction of the roof is higher than the end part, the deflection of the roof 1 and the beams 10a, 10b, and 10c due to its own weight is offset and the deflection of the roof 1 is reduced even in the case of the roof 1 having a wide opening for three vehicles. can do.
Further, since the upper rafter 3 is inclined so that the rear side is lowered, the distance between the front side one mounting part 12 and the upper rafter 3 is larger than the distance between the rear side other mounting part 13 and the upper rafter 3. The connecting members 11a, 11b, and 11c are attached to the one-side attachment portion 12 at the longitudinal ends of 10a, 10b, and 10c, and the longitudinal ends of the beams 10a, 10b, and 10c at the longitudinal intermediate portion of the beams 10a, 10b, and 10c. By attaching the same connecting materials 11a, 11b, and 11c to the other side attachment portion 13, even if the heights of the one side attachment portion 12 and the other side attachment portion 13 are the same, the center portion of the roof 1 is pushed up and bent. There is an effect to reduce. The thing of this embodiment is that the other side attaching part 13 was made higher than the one side attaching part 12, and combined with the fact that the upper rafter 3 is inclined, the action of pushing up the center part of the roof 1 works twice. Thus, a better deflection reduction effect can be obtained.

FIG. 15 shows another embodiment of a connecting structure between the beam 10 and the upper rafter 3. On the upper surface of the beam 10, there is an intermediate mounting portion 33 between the one side mounting portion 12 provided on the front side and the other side mounting portion 13 provided on the rear side, and the one side mounting portion 12 and the intermediate mounting portion 33. The other side mounting portion 13 is formed so as to increase in order. At the longitudinal end portion of the beam 10, as shown in FIG. 15C, the connecting material 11 that connects the beam 10 and the upper rafter 3 is attached to the lowest one-side attachment portion 12. 15 (a), the connecting material 11 is attached to the highest other side attachment portion 13 as shown in FIG. 15 (a), and in the middle between the longitudinal direction center portion and the end portion of the beam 10, As shown in FIG. 15 (b), the connecting material 11 is attached to the intermediate attachment portion 33.
In this way, by providing three or more attachment portions to which the connecting material 11 is attached and by changing the height of each attachment portion, the deflection due to the weight of the roof 1 and the beam 10 can be corrected more precisely.

As shown in FIGS. 5 and 7, the upper rafter 3 has panel receiving portions 7 and 7 for receiving the ends of the roof panels 5 and 5 on both sides along the longitudinal direction on the upper surface, and two rows of panel receiving portions 7. , 7 has a screw insertion portion 35 into which the mounting screw 34 of the panel presser 6 is inserted along the longitudinal direction. Further, the upper rafter 3 has panel support portions 8 and 8 having a substantially L-shaped cross section extending outward from the panel receiving portions 7 and 7 along the longitudinal direction.
A panel presser 6 is mounted on the upper rafter 3 with screws 34, and the panel presser 6 has panel pressers 9 and 9 that face the panel receiving portions 7 and 7 of the upper rafter 3. A rubber bead 36 is attached to the panel receiving portion 7 and the panel holding portion 9, and the end portion of the roof panel 5 is sandwiched between the panel receiving portion 7 and the panel holding portion 9.
The panel support portion 8 of the upper rafter 3 has an upper end 8 a at a position higher than the panel receiving portion 7 and pushes up the roof panel 5.

  The roof 1 of the present carport has panel support portions 8 and 8 projecting outside the panel receiving portions 7 and 7 on the upper rafter 3 as described above, and both ends of the roof panel 5 are panel receiving portions of the upper rafter 3. As shown in FIG. 16, the center side in the width direction is the upper side of the roof panel 5 by being sandwiched between the portion 7 and the panel retainer 9 of the panel retainer 6 and pushing up the roof panel 5 by the panel support portions 8 and 8. Therefore, the roof panel 5 can be prevented from being bent due to its own weight, snowfall, or the like without providing a central frame for receiving the roof panel 5 between the upper rafters 3 and 3 as in the prior art. Since there is no center bone, the cost of parts and the labor of processing and construction can be reduced. Moreover, the designability of the roof 1 is also improved due to the absence of the central bone.

  Next, the construction procedure of this carport will be described. First, the four pillars 14a, 14b, 14c, and 14d are erected at predetermined positions on the ground. Next, as shown in FIG. 13, the corner fittings 17 are attached in advance to the front and rear beams 10a and 10c, and the column insertion portions 17a of the corner fittings 17 are dropped into the hollow portions of the columns 14a, 14b, 14c and 14d from above. The front and rear beams 10a and 10c are connected to the front and rear columns 14a, 14b, 14c and 14d, respectively. Next, as shown in FIG. 14, the connecting member 16 formed by attaching the T-shaped connecting brackets 20 and 20 to the intermediate beam 10b is attached to the four-round pillars 14a, 14b, 14c and 14d by dropping from above. . Thereafter, the upper rafter 3 and the lower rafter 4 are sequentially attached to the front and rear and intermediate beams 10a, 10b, and 10c. Next, the front frame 25, the rear frame 26, and the cross member 30 are attached. Thereafter, the roof panel 5 is placed between the upper rafters 3, 3... And the panel presser 6 is attached on the upper rafter 3 to fix the roof panel 5.

As described above, in this carport, the roof 1 has the upper rafter 3 and the lower rafter 4, the lower rafter 4 is curved in a bow shape, and the longitudinal end of the upper rafter 3 and the lower rafter 4 Since the upper rafter 3 is supported on the support 2 and the upper rafter 3 and the lower rafter 4 maintain the strength in the depth direction of the roof, Can handle a wide frontage without increasing the size. Since no suspension material is required, the design is good.
Furthermore, in this carport, since the rafter 4a also serves as a rain gutter, the pipe connecting the gutter 26a of the roof 1 and the vertical gutter 31 provided on the pillars 14a and 14b can be eliminated, and the design can be further improved. .
The design of the roof 1 of the present carport having a bow rafter 4 curved below the roof 1 is a novel design that cannot be seen on a conventional roof such as a carport, and can appeal high design. .

  The roof 1 of the present carport has panel receiving portions 7 and 7 on the upper rafter 3 and panel supporting portions 8 and 8 positioned outside the panel receiving portions 7 and 7. Since the upper end 8a is at a position higher than the panel receiving portion 7 and pushes up the roof panel 5, the roof panel 5 can be prevented from being bent even if there is no inner bone. Since there is no center bone, the cost of parts and the labor of processing and construction can be reduced. Moreover, the design of the roof is also improved due to the absence of the central bone.

Further, the roof 1 of the present carport has one side mounting portion 12 in which the beams 10a, 10b, 10c are provided on one side in the front-rear direction of the upper surface and the other side mounting portion 13 provided on the other side in the front-rear direction on the upper surface. The other side attachment portion 13 is positioned higher than the one side attachment portion 12, and the connecting members 11a, 11b connecting the beams 10a, 10b, 10c and the upper rafter 3 at the longitudinal ends of the beams 10a, 10b, 10c. 11c is attached to the one-side attachment portion 12, and the connecting members 11a, 11b, 11c are attached to the other-side attachment portion 13 in the middle portion in the longitudinal direction of the beams 10a, 10b, 10c. Since the center part of the left-right direction becomes higher than an edge part, it can cancel with the bending of the roof 1 by dead weight, and the bending of the roof 1 can be reduced. Since the same connecting material 11a, 11b, and 11c can be used in the longitudinal direction edge part and intermediate part of the beams 10a, 10b, and 10c, workability is good. Since the gutter 26a attached to the roof 1 does not bend, drainage is good.
Further, the roof 1 of the present carport has one side mounting portion 12 in which the beams 10a, 10b, 10c are provided on one side in the front-rear direction of the upper surface and the other side mounting portion 13 provided on the other side in the front-rear direction on the upper surface. The upper rafter 3 is inclined so that the other side is lowered, and the connecting members 11a, 11b, and 11c that connect the beams 10a, 10b, and 10c and the upper rafter 3 at the longitudinal ends of the beams 10a, 10b, and 10c. Is attached to the one-side attachment portion 12, and the connecting members 11a, 11b, and 11c are attached to the other-side attachment portion 13 in the longitudinal intermediate portion of the beams 10a, 10b, and 10c, so Since the center portion of the roof becomes higher than the end portion, the deflection of the roof 1 can be offset by the deflection of the roof 1 due to its own weight. Since the same connecting material 11a, 11b, and 11c can be used in the longitudinal direction edge part and intermediate part of the beams 10a, 10b, and 10c, workability is good. Since the gutter 26a attached to the roof 1 does not bend, drainage is good.
Since the roof 1 of the present carport has the other side mounting portion 13 at a higher position than the one side mounting portion 12, and the upper rafter 3 is inclined so that the other side is lower, the center of the roof 1 described above The action of pushing up the part works in a double manner, and a more excellent bending reduction effect is obtained.

In the present carport, the support body 2 has two sets of front and rear gate frames 15 including left and right columns 14a, 14b and 14c, 14d and beams 10a, 10c, an intermediate beam 10b, and four columns 14a, By connecting the front and rear frames 15 and 15 with the connecting member 16 that connects the 14b, 14c, and 14d, the front and rear beams 10a and 10c and the intermediate beam 10b can support the weight of the roof 1 with a wide frontage. The beams 10a, 10b, and 10c can be thinned because they are dispersedly supported. In this carport, the roof 1 is eccentrically supported on the rear side with respect to the support body 2, so that the columns 14a, 14b, 14c, and 14d are not obstructed when the vehicle is taken in and out, so that the car can be taken in and out. It's easy to do. Furthermore, since the four columns 14a, 14b, 14c, and 14d are connected by the connecting material 16 having the intermediate beam 10b, the support 2 is more robust, so that the front and rear columns 14a and 14c, 14b and 14d The interval can be made as narrow as possible, and the ease of taking in and out of the car is further improved.
In addition, the carport has good workability because the connecting member 16 is attached to the four columns 14a, 14b, 14c, and 14d by dropping from above.

  The present invention is not limited to the embodiments described above. The position of the beam with respect to the rafter, the number of beams, and the form of the connecting material can be changed as appropriate. The roof may be a flat roof or an arched roof. The beam only needs to have at least two attachment portions of the connecting material, one attachment portion and the other attachment portion, and may have three or more attachment portions. In the roof of the present invention, the height of the one side attachment portion and the other side attachment portion is the same, and the rafter is inclined so that the other side is lower, the other side attachment portion is at a position higher than the one side attachment portion, The rafters may be arranged horizontally.
