As described above, since the support mechanism and the connecting mechanism according to the present embodiment have the same configuration of the pin device, the number of parts can be reduced. However, the configuration of the support mechanism and the connecting mechanism is not limited to the above configuration, and any configuration may be used as long as the main panel and the panel support member or the main panels arranged vertically are detachably connected to each other. For example, the pin device 20 is omitted from the lower frame 14b of the main panel P1 and only the through hole 14c is provided, and a pin prepared separately from the main panel P1 is inserted into the through hole 14c and the pin hole 10d or the lock hole 14d. Both members may be connected together. Alternatively, both members of the main panel P1 and the panel support member 13 or the upper main panel P1 and the lower main panel P1 may be restrained by a binding band and connected, or on the scaffolding plate 1 side of both members. A pin hole may be provided, and both ends of the U-shaped pin may be inserted into each pin hole to connect the two members.

Further, the hook 5 as the mounting portion according to the present embodiment is rotatably mounted around the cross rail 3 (4), and the main panel P1 is tilted with respect to the axial direction of the vertical column 2. Has an open maintenance means to maintain.

According to this configuration, if the main panel P1 is rotated around the cross rail 3 (4) with the support mechanism or the connecting mechanism released, and then the main panel P1 is maintained in an inclined state by the open maintenance means. Since the main panel P1 is in a half-opened state, the panel device P can exert a louver function to ventilate the inside of the work scaffold W.

In the present embodiment, the open maintenance means is a rod member 37 bridged between the lower end of the main panel P1 and the panel support member 13 or between the lower end of the upper main panel P1 and the upper end of the lower main panel P1. However, the rod member 37 is an example of the open maintenance means, and the configuration of the open maintenance means is not particularly limited as long as the main panel P1 can be maintained in the open state. For example, the main panel P1 is maintained in an open state by providing a detent mechanism for preventing the hook 5 from rotating with respect to the cross rail 3 (4) and detenting the main panel P1 in an inclined state. You may try to do it.

The main panel P1 according to the present embodiment has a rectangular and hollow frame body 14 and a sheet 15 stretched on the frame body 14 via a sheet stretching mechanism S, and the sheet stretching mechanism S is a sheet. A plurality of eyelets 15a provided along the outer circumference of the frame 15 at predetermined intervals, a first hole 14e provided at a position facing each eyelet 15a on the outer circumference of the frame body 14, and a first of the inner circumferences of the frame body 14. The eyelet 15a is provided with the eyelet 15a and the first hole 14e facing each other with the second hole 14f, which is provided at a position facing the hole 14e and whose anti-seat side end is closer to the sheet 15 side than the first hole 14e. And the pin 27 inserted into the first hole 14e and the second hole 14f, and one of the pins 27 hung on one side on the eyelet 15a side and the other side on the anti-eyelet side with the frame body 14 of the pin 27 sandwiched. It has an elastic ring 28 that urges the side to the anti-seat side.

According to this configuration, since tension can be applied to the sheet 15 by the elastic ring 28, the sheet 15 can be spread on the frame body 14 without loosening.

The main panel P1 may be configured by attaching a panel material made of wood, synthetic resin, or metal to the frame body 14, but as in the present embodiment, the sheet 15 is extended on the frame body 14. Since the main panel P1 can be made lighter, the main panel P1 can be easily carried and workability is improved.

Although the preferred embodiments of the present invention have been described in detail above, it is natural that modifications, modifications and changes can be made without departing from the scope of claims.
