Construction sites often have openings on the floor for equipment delivery and maintenance. It is necessary to temporarily install safety facilities at such openings to prevent workers from accidentally falling. Conventionally, safety facilities for openings include a lid that covers the entire surface of the opening with a steel plate or wooden board, or a safety fence that surrounds the opening with steel pipes or wooden boards.
これらは全て開口部の大きさや形状に合わせて
加工せねばならず、又、工事完了と共に不要とな
り再利用できない欠点があつた。 All of these had to be processed to match the size and shape of the opening, and they also had the disadvantage that they became unnecessary once the construction was completed and could not be reused.
