  In recent years, laying of platform doors has been increasing as one of the measures for preventing falling on railway platforms.

  The platform door is installed at a position close to the leading edge of the platform, that is, the rail side. Furthermore, when laying a platform door on an existing platform, it is often performed at night in consideration of railway operation. From such a situation, it is assumed that during construction, an operator falls to the rail side or the platform door device itself is dropped.

  In order to prevent such accidents during work, a plurality of poles are set up at predetermined intervals along the edge of the platform, and iron pipes are clamped laterally to connect the poles to construct a temporary fence.

  As a pole used for such a temporary fence structure, a safety induction pole as shown in a conceptual structure in FIG. 1 has been used.

  That is, FIG. 1 is a conceptual side view of a conventional safety induction pole. A lower support member 10 is fixed to a lower end portion of the support column 1 having a predetermined length. Further, the upper support member 11 is fixed at a predetermined height position from the lower support member 10. The upper support member 11 has a downward screw locking portion 12 whose height can be adjusted.

  When the pole is set up on the edge of the platform 2, the lower support member 10 is associated with the lower surface 20 of the edge of the platform 2, and the screw locking portion 12 of the upper support member 11 is connected to the edge of the platform 2. Corresponding to the upper surface side 21. And it is a structure of adjusting the intensity | strength of the holding | grip of the edge part of the platform 2 by the upper side support member 11 and the lower side support member 10 by rotationally fastening the screw of the screw latching | locking part 12. As shown in FIG.

  On the other hand, the structure of the edge part of the existing platform 2 is various, and its thickness and form are various. That is, FIG. 2 is an example, and in FIG. 2, the form (1) is a standard platform shape and thickness, whereas the form (2) has a short depth direction. In (3), the lower shape of the platform is inclined like a jaw. Furthermore, in the form (4), the depth direction is short and the height of the end edge is large.

  Thus, the depth D and the height H of the edge part of the platform 2 are various. Further, as shown in FIG. 2 (3), the lower structure of the edge portion may be a “jaw shape” rather than a flat shape.
