Description

Opening cover device { OPENING COVER APPARATUS FOR CONSTRUCTION SAFETY }

The present invention relates to an opening covering device, and particularly to an opening covering device that can be changed in size and installed to suit the opening of a construction site for construction safety.

In general, during the construction process of a building, AD (Air Duct), PS (Pipe Space), EPS (Electric Pipe Space), and DS (Dust) are used to allow air, pipes, and conduits to pass through the floor slab or to lower waste. Openings such as space must be considered.

These openings are inevitably left open during construction, but are closed only after the interior and exterior are completed in the final stage of construction, so they are not exposed when construction is completed.

However, if these openings are left open at a construction site, which is usually very dark because sufficient lighting is not provided during construction, there is a risk that construction workers may fall or construction materials may fall through the openings, especially in high-rise buildings. In the case of a building, the openings are located at the same location on each floor from high to low, so the risk of falls is very high.

Meanwhile, since these openings are also used as passageways for construction materials between each floor during the construction process, they cannot be completely covered until the opening is finished. Conventionally, a panel of an appropriate size is simply placed on top of the opening to temporarily cover it or close the opening. Warning signs alerting people to the risk of falling have been installed around the area, but it is difficult to prevent accidents with this method.
