補助ボード1上に人が乗って歩くことができる。When the auxiliary board 1 is used to prevent falling after the mounting bracket 5 is attached to a required portion of the building frame building T, as shown in FIG. 9, the auxiliary board 1 is indicated by a phantom line in FIG. From the raised state as shown in the figure, the locking metal fitting 3 of the auxiliary board 1 is inserted into the first cutout groove 11 forming the locked portion 13 of the mounting metal fitting 5, and one of the locking metal fittings 3 is inserted. Side (lower side) vertical rod portion 6 is engaged with bent portion 11a of first notch groove 11, and auxiliary board 1 is placed in the posture shown in the same figure with vertical rod portion 6 engaged with this bent portion 11a as the center. While rotating forward, the vertical rod portion 6 on the other side (upper side) of the locking metal fitting 3 is engaged with the lower end portion of the second cutout groove 12 which also constitutes the locked portion 13 to obtain the posture shown in FIG. , By this, auxiliary board 1
Is held in a fall prevention posture that closes the gap S between the scaffolding plate 2 and the building K. The state where the auxiliary board 1 is held in the fall prevention posture is shown in the right half of FIG. 3, the right half of FIG. 4 and the left half of FIG. 5 (shown in phantom), respectively. A person can walk on the auxiliary board 1 in the fall prevention posture.

About half of the state is blocked. The gap s is completely covered by both the auxiliary boards 1 and 1 adjacent to each other in the fall prevention postures and placing the cover bodies 4 and 4 in the closed position. Further, the cover body 4 is supported on the small U-shaped frame portion 9b of the mounting member 5 so as to be flush with the upper surface of the auxiliary board 1 at the closed position where the gap s is closed, and this state is shown in FIGS. It shows in FIG.

示す。Next, when the auxiliary board 1 is used as a skirting board and when the fall prevention posture is changed to the skirting board posture, the cover body 4 is inverted from the closed position and folded to the open position. After that, the auxiliary board 1 is rotated from the posture shown in FIG. 9 (fall prevention posture) to the posture shown in FIG. 9 (also the posture shown by the phantom line in FIG. 10), and from this posture, the first cutout groove 11 When the vertical rod portion 6 of the locking metal fitting 3 engaged with the bent portion 11a is disengaged from the bent portion 11a, the entire auxiliary board 1 is further rotated to stand up as shown by the solid line in FIG. The upper and lower vertical rods 6 and 6 of the stopper 3 are second
The auxiliary board 1 is retained in a skirting board posture by engaging with the upper and lower ends of the notch groove 12, respectively, and is ready to be used as a skirting board suspended from one end of the scaffolding plate 2. Thus, the state in which the auxiliary board 1 is held in the skirting board posture is as shown in FIG.
0, the left half of FIG. 3, the left half of FIG. 4, and FIG.

姿勢変更を簡単容易に行うことができる。When the above-mentioned skirting board posture is changed to the fall prevention posture again, it is advisable to rotate the auxiliary board 1 from the solid line state (fall prevention posture) of FIG. 10 to the postures of FIG. In this way, the posture of the auxiliary board 1 can be easily and easily changed from the fall prevention posture to the fall prevention posture and from the skirting posture to the fall prevention posture.

Bent portion 11a of the first cutout groove 11 that constitutes the locked portion 13
Since the auxiliary board 1 is engaged with the lower end of the second cutout groove 12, there is no risk that the locking metal fitting 3 will come out upward unless the auxiliary board 1 is rotated in a specific direction. It does not float up and leave.
Further, since the locking metal fitting 3 is formed in a U shape by the vertical rod portions 6, 6 and the horizontal rod portion 7, when the locking metal fitting 3 is hooked to the locked portion 13, The movement of the auxiliary board in the longitudinal direction of the auxiliary board is restricted by the rod portion 7, and there is no possibility that the locking fitting 3 will come out of the locked portion 13 and the auxiliary board 1 will come off the mounting fitting 5.

助ボードが取付金具から外れることがない。 According to the first aspect of the present invention, the locking metal fittings are provided with the auxiliary boards having substantially the same length as the scaffolding board attached to the horizontal frame of the building frame of the frame scaffolding, projecting at both ends in the longitudinal direction of the auxiliary board. It is designed to be attached to the building frame terrain so that the posture can be changed between the fall prevention posture and the skirting posture through the mounting metal having the locked portion where By attaching it, it is possible to prevent things from falling through the gap between the scaffolding board and the building to ensure work safety, and if the auxiliary board is installed in the skirting board position, it can be used as a skirting board. It is possible to prevent objects from sliding down. Further, according to the present invention, the fall prevention of the auxiliary board is prevented.
Change the posture from the stop posture to the skirting posture, or drop from the skirting posture.
You can easily and easily change the posture to the lower-prevention posture.
It Also, the auxiliary board is held in the fall prevention posture.
At this time, both vertical rods of the locking fitting form the
Engages with the bent portion of the V-shaped first cutout groove and the lower end of the second cutout groove
Therefore, there is no risk of the locking metal fittings coming out upwards,
Therefore, the auxiliary board floats up due to strong winds, etc.
Never. Also, the locking metal fittings are
Since it is formed in a letter shape, the locking metal fittings can be hooked on the locked part
The auxiliary board is in the longitudinal direction by the horizontal rod
Movement is restricted and the locking metal fittings slip out of the locked
The auxiliary board does not come off from the mounting bracket.

Since it is pivotally attached so that it can be opened and closed between the open position where it is inverted to open and folded on the auxiliary board, the cover body must be set to the closed position when the auxiliary board is installed in the fall prevention posture. As a result, it is possible to prevent objects and the like from falling through the gap. Further, since the cover body is supported on the mounting member at the closed position, no special support member is required and the structure is simplified. Further, since the cover body is folded on the auxiliary board in the open position, it does not come to bear when the posture of the auxiliary board is changed.
