It is common to first build a skeleton of reinforced concrete and then work on the interior of the skeleton. In this case, after the construction is performed on the lower floor, the materials used there, such as large pulling materials and pipe supports, must be lifted to the upper floor.

持ち上げている。Since materials such as large pulling materials and pipe supports are long, it is troublesome to lift them upstairs by stairs or lifts. Therefore, through-holes called floor-use holes are formed in the floor that separates the upper and lower floors of the building, from which construction materials such as large pulling materials and pipe supports on the lower floor are manually lifted to the upper floor.

It is made up of holes with a size of about m, and in apartments and the like, three or four places are provided on one floor. And there is a danger that workers will fall or that materials will fall to the lower floor and hit workers on the lower floor.When not in use, these holes are closed with a wooden lid, for example. ing.

There was danger. In addition, the wooden lid that covers the floor hole is quite heavy and has no handle,
It was difficult to carry, and if dropped, there was a high risk of injury to the feet of workers. In addition, since this wooden lid has a considerable thickness (plate thickness of about 30 mm),
There was also a danger of workers tripping over and falling.
