Description

  The present invention relates to a warning plate laid on the floor surface of a scaffolding plate, for example, and more specifically, on the ground or underground for transporting various materials and work tools in bridge construction or construction work sites, etc. The present invention relates to a warning plate that prevents a worker or the like from entering a dangerous area such as the periphery of the formed opening to prevent a fall accident into the opening.

  For example, in bridge construction, etc., a chain or rope etc. is suspended via hooks attached to the side or bottom of the bridge to create a scaffold for work, rusting, paint painting, other maintenance work etc. are performed ing. The opening formed between the scaffold plate and the scaffold plate is used for transporting paint and various tools. There is also a place (opening) where the scaffold plate and the scaffold plate are not connected. Although it is recommended that handrails or intrusion prevention fences, etc. be installed in the dangerous area around the opening as a safety measure, these safety measures are an obstacle to the progress of work for workers on site. Or it may not be installed for reasons such as complexity. There is an accident in which the operator concentrates too much on the work, forgets that the opening is nearby, and falls into the opening. Various safety tools, alarm devices, and the like have been proposed to prevent accidents of falling into these openings.

  For example, the “falling safety device” disclosed in Patent Document 1 (see page 1 and FIG. 1) is intended to solve the problem to be solved when a person performs a predetermined work by opening the grating floor surface. It is supposed to provide a safety device that prevents falling from the opening of the door. As a solution to this, the safety device for fall prevention is composed of a lid and a lid support frame, and the lid covers the opening of the grating floor surface and is projected from the grating floor surface. The construction is such that the other person can recognize that there is an opening on the grating floor surface. Further, the “alarm mat” of Patent Document 2 (see page 1 and FIG. 2) is to provide an alarm mat that does not require any power source. The solving means (configuration) includes a plurality of step-like elastic protrusions that can be stepped down, for example, hook-shaped elastic protrusions arranged at appropriate intervals on the upper surface of the mat, and communicates with an air chamber in the elastic protrusions that are compressed when stepped down. The flute is attached to the outside of the elastic protrusion.
