  (b) The roof scaffolding 10 is engaged without the snow retaining hook 30 being detached by the anti-slip means such as the anti-scattering bolt 33 without being detached by the anti-slip member 30 and blown off by wind force such as gust and scattered around. There is no

  (c) The roof scaffolding 10 engages the panel hooking portion 40 provided on the scaffolding body 20 with the side 202F of the solar energy collection panel 200 on which the scaffolding body 20 is placed facing the water upper side 202U of the water upper frame 202U. Together, they prevent slipping on the sloped roof 101.

  It is sufficient if the panel hooking portion 40 provided on the scaffold main body 20 is installed so as to engage only with the side surface 202F facing the water upper side of the water upper frame 202U of the solar energy collection panel 200, and the installation workability is simple.

  The panel hooking portion 40 provided on the scaffold main body 20 is engaged with the side 202F of the solar energy collection panel 200 facing the water upper side of the water upper frame 202U to be prevented from slipping, requiring the presence of other anti-slip members The installation structure is simplified.

  (d) Here, in the roof scaffold 10, the snow retaining hook portion 30 is formed at one end of the scaffold main body 20, and the panel hooking portion 40 is formed at the other end of the scaffold main body 20. The panel hooking portion 40 can be switched and set between a working position projecting from the scaffold main body 20 and a storage position not projecting from the scaffold main body 20 so as to engage the side 202F of the solar energy collection panel 200 facing the water upper side Be done. This makes it possible to use a single roofing scaffold for i. Or ii. Below (Figure 12). In FIG. 12, reference numeral 40F denotes a panel hooking portion 40 set at the storage position.

  i. When the snowstop member 300 which protrudes upward from the water upper side of the side 202F facing the water upper side of the water upper side frame 202U of the solar energy collection panel 200 on which the scaffold main body 20 is mounted is installed.

  As in the case of two roof scaffolds 10 installed on the upper side and the lower side of water in FIG. 12A and one roof scaffold 10 installed on the upper side of water in FIG. The snow catch portion 30 provided at one end portion of the gear is engaged with the above-described snow catch member 300 (the side surface 302F facing the water upper side). At this time, the panel hooking portion 40 provided at the other end of the scaffold main body 20 is set at the storage position and placed on the frame of the solar energy collection panel 200 below the water.

  ii. When the snowstop member 300 projecting upward from the water upper side of the side 202F facing the water upper side of the water upper side frame 202U of the solar energy collection panel 200 on which the scaffold main body 20 is mounted is not installed.

  As in the case of one roof scaffold 10 installed under the water of FIG. 12 (B) and two roof scaffolds 10 installed above the water and below the water of FIG. 12 (C), the scaffold main body A panel hooking portion 40 provided at the other end of 20 is set at the working position, and is engaged with the side surface 202F of the water upper frame 202U of the solar energy collection panel 200 facing the water upper side. At this time, the snow catch 30 provided at one end of the scaffold body 20 is positioned on the frame of the solar energy collection panel 200 below the water.

  In addition, when the roof scaffolding 10 uses the snow catches 30 to prevent slipping, by setting the panel catches 40 in the storage position, the sun due to the panel catches 40 protruding from the scaffold main body 20 The scratch of the energy collection panel 200 is prevented. Further, by setting the panel hooking portion 40 to the storage position, the panel hooking portion 40 does not protrude from the scaffold main body 20, so that it is easy to handle when transporting or storing the scaffold.

  (e) According to i. of (d) above, the snow catch hook portion 30 of the roof scaffold 10 installed on the underwater side is the water upper frame 202U of the solar energy collection panel 200L on the water side and the sun on the water upper side The energy collection panel 200H is provided so as to engage with a snow stop member 300 (a side surface 302F facing the water upper side) protruding upward from the gap K with the underwater frame 202D. Thereby, the roofing scaffold 10 can be stably and orderly mounted on the plurality of solar energy collecting panels 200 fixed on the sloped roof 101.

  (f) According to ii. of (d) above, the panel hooking portion 40 of the roof scaffold 10 installed on the under water side is the water upper frame 202U of the under water solar energy collection panel 200L and the water on the water upper side The gap K between the collection panel 200H and the lower frame 202D is inserted so as to engage the side 202F of the upper solar energy collection panel 200L facing the upper water of the upper water frame 202U. Thereby, the roofing scaffold 10 can be stably and orderly mounted on the plurality of solar energy collecting panels 200 fixed on the sloped roof 101.

  The roof scaffolding may be used even if the snow catch hook and the panel hook are selectively attached to the end of the scaffold main body, as described in (1) or (2) below. good.

  (1) When a snow stopper that projects upward from the water upper side of the side facing the water upper side of the solar energy collection panel on which the scaffold main body is mounted is attached, the snow hook is attached to the end of the scaffold main body The snow catch is engaged with the above-described snow catch.

  (2) Attach a panel hook to the end of the scaffold main body when the snow stopper that projects upward from the water upper side of the side facing the water upper side of the solar energy collection panel on which the scaffold main body is mounted is not installed. The panel hooks are engaged with the side of the solar energy collection panel facing the water.

  The embodiment of the present invention has been described in detail with reference to the drawings, but the specific configuration of the present invention is not limited to this embodiment, and even if there is a design change or the like within the scope of the present invention. Included in the present invention. For example, the snow retaining hook and the panel hook constituting the roofing scaffold of the present invention may be integrally formed on the scaffolding body.

  In addition, the snow retaining hook and the panel hook constituting the roof scaffold of the present invention are not necessarily provided on the water upper side of the roof scaffold placed on the solar energy collecting panel, but on the water underside. It may be provided.

  In addition, the solar energy collection panel on which the roof scaffold of the present invention is installed may be a solar water heater or the like.

  In addition, the roof scaffolding having the snow retaining hook portion of the present invention can also be used on a slope roof where the solar energy collection panel is not fixed, as long as the slope roof is provided with the snow retaining member.

  ADVANTAGE OF THE INVENTION According to this invention, while simplifying the installation workability | operativity of the scaffold for roofs and simplifying an installation structure, the scaffold for roofs can be stably installed on a slope roof, without slipping.

  Moreover, according to the present invention, while simplifying the installation workability of the roof scaffolding and simplifying the installation structure, the roof scaffolding is stable without slipping on the solar energy collecting panel fixed on the sloped roof. Can be installed.
