The gap S can be closed by a simple operation of simply expanding the 1 'from the folding position to the use position, and a special operation for closing the gap is not required. Further, since the gap plates 11, 11 'are integrally provided with the scaffold plate main body 8, it is convenient for transportation and storage.

[0021]

According to the first aspect of the present invention, the gap between the opposing ends of the two scaffolding plates spanned on both sides of the cross member of the scaffolding frame is formed at both ends of the scaffolding plate main body. It can be closed by the gap plate attached to the gap, thereby preventing the bolts and nuts from falling from the gap, and eliminating the possibility that the worker may get caught in the gap and fall down, and secure the work safety .

In addition, while performing the work of bridging the scaffolding plate to the scaffolding frame, a simple operation of simply expanding the gap plate pivotally attached to the end of the scaffolding plate body from the folding position to the use position is performed. The gap can be closed, and no troublesome work is required for closing the gap. In addition, since the gap plate is integrally provided with the scaffold plate body, it is convenient for transportation and storage.

According to the second aspect of the present invention, in a state where the gap is closed by the gap plate of the scaffold plate, the gap between the concave notch or the convex piece of the gap plate of one scaffold plate and the other scaffold plate. Since the convex piece portion or the concave notch portion of the plate is fitted unevenly, both scaffold plates can be prevented from shifting from each other in the lateral direction, and the gap plate of both scaffold plates closing the gap is formed by both scaffold plates. There is no step between the scaffold plate body and the plate, it is almost flush, and there is no need for the operator to catch his feet.

According to the third aspect of the present invention, the gap plate is
At the use position, the tip of the gap plate is supported on the scaffold plate body of another scaffold plate. Therefore, even if a load is applied to the gap plate, the gap plate is not easily deformed, and the gap plate can be stably arranged.

According to the fourth aspect of the present invention, since the gap plate is formed so as to avoid the locking hook which is locked to the cross member of the scaffolding frame, the locking hook is formed on the upper surface of the scaffold plate body. Even if it protrudes higher, the gap plate can be arranged along the upper surface of the scaffold plate body, regardless of the protrusion height of the locking hook, thereby forming a step between the gap plate and the scaffold plate body. Can be avoided.
