That is, as shown in FIG. 9, a support member 102 is attached to a part of the plurality of purlins 50. The support member 102 is made of a steel material whose longitudinal direction is the girder direction of the building 10. The cross-sectional shape of the support member 102 orthogonal to the longitudinal direction is formed in a substantially J shape by the side wall portion 104, the upper wall portion 106, and the return wall portion 108. The side wall portion 104 is a plate-shaped member having the same thickness direction as the web 64 of the purlin 50. The upper wall portion 106 is connected to the upper end portion 104A of the side wall portion 104, and is a plate-shaped member having the same thickness direction as the flange 60 of the purlin 50. The upper surface 106A of the upper wall portion 106 can be arranged on substantially the same surface as the upper surface 60A of the flange 60 on the upper side of the purlin 50. The return wall portion 108 is connected to an end portion opposite to the end portion to which the side wall portion 104 of the upper wall portion 106 is connected, and has the same thickness direction as the web 64 of the purlin 50 and is substantially below the building. It is a plate-shaped member protruding to the side. The amount of protrusion of the return wall portion 108 with respect to the upper wall portion 106 is set so as not to overlap with the hinge portion 110 described later in the thickness direction view of the return wall portion 108 as an example.

Further, although not shown, the support member 102 has substantially the same lengthwise dimension as the width dimension of the roof panel 66 and is larger than the width dimension of the roof frame 30A, similarly to the support members 52 and 54 of the first embodiment. It is set small and is arranged substantially in the center of the roof frame 30A in the width direction.

The support member 102 is provided with a hinge portion 110 at one end portion 102A in the longitudinal direction. The hinge portion 110 has a through hole 112 provided in the side wall portion 104 of the support member 102 and penetrated in the plate thickness direction of the side wall portion 104, and a fastener 74 inserted into the through hole 112. .. The fastener 74 is also inserted into the through hole 76 formed in the web 64 of the purlin 50 corresponding to the through hole 112, and the support member 102 is rotatably fastened to the purlin 50. As a result, the support member 102 itself can be rotated in the vertical direction of the building.

(Action / effect of the second embodiment)
Next, the operation and effect of the second embodiment will be described.

Even with the above configuration, the same effect as that of the first embodiment can be obtained because the support member 102 is configured in the same manner as the roof structure of the first embodiment except that the cross-sectional shape of the support member 102 is different from that of the purlin 50. Further, the cross-sectional shape of the support member 102 orthogonal to the longitudinal direction is formed in a substantially J shape by the side wall portion 104, the upper wall portion 106, and the return wall portion 108. In other words, the support members 52 and 54 of the first embodiment have a shape without the lower flange 58 (see FIG. 8). Therefore, the cost of the support member 102 can be reduced.

In the first and second embodiments described above, the support members 52, 54, and 102 are configured to be rotatable by the hinge portions 70 and 110, but the present invention is not limited to this, and the support members 52, 54, and 102 can be moved substantially in the vertical direction of the building. The support members 52, 54, and 102 may be moved by a guide portion formed of a rail or the like.

Further, the fitting portion 92 and the fitting portion 93 are configured to be fitted in the vertical direction of the building, but the present invention is not limited to this, and a fitting structure may be used in which the fitting portion 92 and the fitted portion 93 are fitted in other directions.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above, and it is possible to carry out various modifications other than the above within a range not deviating from the gist thereof. Of course.
