However, the above-mentioned conventional fire section walls have the following problems. The conventional fire protection partition walls including the fire protection partition walls 3 and 6 all have a fire protection function for the partitions on both sides thereof. However, when a fire prevention partition wall is installed between a pit section such as an elevator shaft and a section adjacent to the pit section, the possibility of a fire occurring from the pit section side is extremely low. Since there is no combustible material, it can be said that the fire prevention function against a fire from the pit section is useless, and there is room for cost reduction in this regard. In addition, in order to attach the fire-resistant wall plate 2 to the pit section side, it is necessary to construct a large scaffold or the like, and there is a problem that it takes much time and effort.
