Description

The present invention relates to an installation structure for a roof scaffold that is installed on a sloped roof to which a solar energy collection panel such as a solar cell module or a solar water heater is fixed.

  The solar energy collection panel has functions such as converting sunlight into electric power, and is fixed to the sloped roof to receive sunlight. This solar energy collection panel is affected by changes in weather, dust and flying objects, and the transparency of the light receiving surface of the panel body may be impaired, resulting in a decrease in power generation output or the like, or damage or failure. Therefore, maintenance such as cleaning and repair is required for the solar energy collecting panel.

  For this reason, on the roof to which the solar energy collecting panel is fixed, a roof scaffolding as described in Patent Document 1 for an operator is provided for maintenance of the roof itself and maintenance of the solar energy collecting panel. It is used by being installed on the solar energy collection panel.

  At this time, the solar energy collection panel has a panel body and left and right frames provided on at least two sides of the panel body facing each other. The roof scaffold includes a top surface portion disposed opposite to the panel body of the solar energy collecting panel, left and right side portions depending on the left and right sides of the top surface portion, and lower ends of the left and right side portions. The left and right placement parts placed on the left and right frames of the solar energy collecting panel and the left and right engagements arranged at the lower ends of the left and right side parts and engaged with the side surfaces of the left and right frames A part.

  As a result, the roof scaffold is placed in the state where the mounting portions are mounted on the left and right frames of the solar energy collection panel fixed to the sloped roof, and the left and right engaging portions are aligned along the gradient direction of the solar energy collection panel. The top surface portion can be disposed at a position that is engaged with the side surfaces of the left and right frames and is away from the panel main body with respect to the solar energy collection panel. The operator can easily and efficiently perform various operations on the top surface without affecting the panel body of the solar energy collection panel.

It will prevent sliding on the sloped roof.

  It is sufficient if the hook portion provided at one end of the scaffold body is installed so as to engage with only one side surface of the water-side frame of the solar energy collecting panel, and the installation workability is simple.

The hook portion provided at one end of the scaffold body engages with the side facing the water side of the water upper frame of the solar energy collection panel and is prevented from slipping, and does not require the presence of other anti-sliding members, The installation structure is simplified.
(b) The hook of the roof scaffolding installed under the water is inserted into the gap between the water-side frame of the water-side solar energy collection panel and the water-side frame of the water-side solar energy collection panel. The underwater solar energy collecting panel is installed so as to engage with the side surface of the underwater frame facing the overwater side. Thereby, a plurality of roof scaffolds can be neatly juxtaposed in the gradient direction on a plurality of solar energy collecting panels fixed on the gradient roof.
