It is located on the side and is arranged so that the edge portion of the roof 20 is sandwiched between the support portion 313 and the holding portion 312.
  • This rotation of the support portion 313 may be performed by a worker on the roof by turning the support portion 313 by hand, or when the nut 15 is tightened with a nut fastener (for example, a wrench, an electric wrench) (not shown). You may rotate it around with you. At the time of this rotation, the side surface of the support portion 313 comes into contact with the stopper portion 312a of the pressing portion 312, and further rotation (rotation) is prevented.

It is fixed to 313, and a washer 17, a spring washer 16, and a nut 15 are preliminarily attached to the bolt 14 in this order from below (from the holding portion 312 side). Therefore, the fitting work of the holding portion 312, the rotating work of turning the support portion 313 by hand, and the tightening work of the nut 15 to the bolt 14 by the nut fastener can be performed from the roof.
  • the stopper portion 312a is formed on the pressing portion 312 and the stopper portion 312a is configured to prevent the support portion 313 from rotating, the nut 15 can be easily tightened from the roof. All you have to do is work. Therefore, since all the work can be done from the roof, the worker does not have to put his head in the opening and work from the underside of the roof. As a result, it becomes possible to easily, quickly, and extremely safely attach the second opening reinforcing member 310. Further, by providing the stopper portion 312a for preventing the rotation, the support portion is incorporated in an appropriate position, so that confirmation after mounting becomes unnecessary, and one worker can surely perform the work.
  • the second opening reinforcing member 310 of the present embodiment includes a main body member straddling the opening 21 of the roof 20 like the first opening reinforcing member in the first to third embodiments. It is an opening reinforcing member provided only at the edge of the opening 21.
  • a plurality of first opening reinforcing members 10, a plurality of first opening reinforcing members 110, or a plurality of first opening reinforcing members 210 provide the opening 21. They are installed at predetermined intervals along the extension direction of the openings 21 so as to straddle them.
  • the second opening reinforcing member 310 of the present embodiment is in the second embodiment along the extension direction of the opening 21 between the first opening reinforcing members 10 in the first embodiment. It is installed between the first opening reinforcing members 110 in the above, or between the first opening reinforcing members 210 in the third embodiment.
  • the installation intervals of the first opening reinforcing members 10, 110 or 210 are 600 mm intervals in strong wind / snow areas recommended by the test by the Building Materials Testing Center, and 750 mm intervals in other areas. If there is, the connection between the roofing material and the skylight becomes stronger by installing the second opening reinforcing member 310 of the present embodiment between the first opening reinforcing members 10, 110 or 210. , Watertightness is greatly improved.
  • FIG. 22 shows a skylight provided so as to cover the opening 21 and a second opening reinforcing member 310 of the present embodiment in a cross section along the opening reinforcing member.
  • a pair of second opening reinforcing members 310 are attached to the edge portions of the opening 21 of the roof 20.
  • the light diffusing plate member 30 is fixed with screws or the like (not shown).
  • a packing or the like (not shown) is inserted between the gantry 22 and the light diffusing plate member 30, and is in a watertight state.
  • the light diffusing plate member 30 is a lightweight hollow multi-layer plate made of resin (for example, made of polycarbonate) that covers the opening 21.
  • the light diffusing plate member 30 has a main function of diffusing and transmitting the sunlight transmitted through the glass daylighting plate 31, but prevents the dew condensation water generated inside the glass daylighting plate 31 from falling and the glass daylighting plate 31. It also has the function of preventing water leakage in the event of damage and improving the heat insulating function.
  • the glass lighting plate 31 and the lighting plate support member 32 are further attached to the frame 22 above the light diffusion plate member 30 with screws or the like (not shown).
  • the lighting plate support member 32 is a metal (often iron) member for supporting the glass lighting plate 31 from below, and in the present embodiment, the lighting plate support member 32 is fixed to the lighting plate 22 across the frame 22.
