The deck 30 of is configured. Since this structure is configured up and down, a multi-layered structure is possible. Therefore, since logistics can be accommodated in a multi-story building, there is an advantage in that the storage space can be expanded. Of course, stairs or ladders that can go up and down to each floor are constructed.

However, in the case of a warehouse in which the mezzanine 1 is installed, most of the stored items are inflammable and electrical facilities such as lighting and air conditioning units are installed in a complex manner, so fires due to overcurrent or short circuit are frequent. Therefore, the Fire Protection Act mandates the installation of fire detection sensors, sprinklers, and fire doors (D).

However, in the case of the fire door D, it cannot descend from the top of the mezzanine 1 and pass through the deck 30 to reach the floor. Therefore, since the fire occurring in the mezzanine 1 cannot be initially blocked, it spreads out of control into a large-scale fire, resulting in a catastrophic accident of life and property loss.

In order to solve this problem, it is possible to construct a gap through which the fire door (D) can pass through the deck 30, but when such a gap is formed, the wheel of the cart is missing and movement becomes inconvenient, and the operator's feet are missing, resulting in a safety accident. can occur, so it is currently not possible to create a gap.
