Description

  The present invention relates to a roof of an R-shaped simple building that can be manufactured in a trapezoidal shape according to a trapezoidal site.

  As shown in FIG. 8 (a), the rounded roof used for carports and the like has a plurality of bent right and left girders 90a and 90b arranged in an arcuate shape. The rafters 91, 91,... Are laid in parallel in the front-rear direction and a roof panel 92 is attached on the adjacent rafters. When installing a carport on a trapezoidal site, it is necessary to cut the shape of the roof into a trapezoid according to the shape of the site. When the above-mentioned rounded roof is cut into a trapezoidal shape, as shown in FIG. 8 (b), the cut surfaces 91a of the cut rafters 91 rise upward as the cut length increases. The girder 90b disposed on the cutting edge cannot be joined to the cut surface of the rafter. For this reason, it has been impossible in the past to cut an R-shaped roof into a trapezoid to match the trapezoidal site.

In Patent Document 1, a straight beam member 3 is connected to a support column, and a plurality of spacers 7a and 7b with different heights are set on the beam member 3 so as to be higher at the center in the longitudinal direction of the beam. It is placed on the spacer, the main building materials 5a and 5b are installed in the direction intersecting the beam material, and a large number of arched rafters 9 bent into an arch shape are arranged on the main building material so as to intersect the main building material. The structure which hangs the roofing board material 13 on the arch-shaped rafter is disclosed.
If the top end of the beam 3 of the roof of this structure is cut obliquely to make a trapezoidal shape and cut diagonally beyond the main building 5b on the front side of the beam, the main building 5b is cut halfway to support the arched rafter 9 In addition, the end of the cut main building 5b must be connected to the beam or the beam 3 in order to maintain the strength of the roof, and the workability is significantly reduced. It is not compatible with.
