  The present invention relates to a roof material support structure and a method for constructing a roof frame using the same.

  Some roof frames of structures such as factories and station buildings use folded plates for roofing materials. FIG. 7 shows an example in which a tight frame 101 is welded onto a purlin 103 and a folded plate 105 is attached to the tight frame 101.

  The tight frame 101 is a corrugated roofing material support tool in which trapezoidal peaks and troughs are alternately repeated, and a corrugated steel plate in which trapezoidal peaks and troughs are alternately repeated is used for the folded plate 105. It is done. The folded plate 105 is arranged with its crests aligned with the crests of the tight frame 101, and the crests are fixed by fasteners (not shown) such as bolts and nuts attached to the tight frame 101.

  FIG. 8 shows an example of the construction method of the above-mentioned roof frame. In FIG. 8, the left figure is a view of the roof frame as seen from the front, and the right figure is a figure of the roof frame as seen from above.

  In this example, as shown in FIG. 8 (a), a steel frame is erected and a column beam 4 is provided with a shed beam 2 in the folded plate flow direction. Are installed in parallel. A temporary handrail (not shown) is attached to the roof frame, and the worker works with a safety device attached to the handrail.

  Further, as shown in FIG. 8B, a roof construction scaffold 107 is laid between the purlins 103, and a spark curing 109 such as a sheet is installed below the purlin 103. And the tight frame 101 is welded on the main building 103 as shown in FIG.8 (c).
