Abstract

PROBLEM TO BE SOLVED: To make it possible to ensure the strength of each of quasi-fire resisting face plates as quasi-fire resisting construction by arranging a plurality of quasi-fire resisting face plates for putting a cemented chip board with specific side in thickness and width on a plywood having smaller width than specific size of a building widthwise. SOLUTION: An inorganic face member is connected to a plywood 3 as a wooden plate member in a quasi-fire resisting floor face plate production line. In that case, the inorganic face member is cemented chip board 2 having thickness of at least 12mm. While, two long side beams are connected to each other with a joist 17 in a floor panel production line. Quasi-fire resisting face plates 1 produced in a fire resisting floor member production line are subsequently delivered to the floor panel production line therefrom, and the face plates 1 are successively mounted from the end of a building unit 10. In that case, the occurrence of a gap between the ends can be prevented by bringing into contact with the ends of the cemented chip board 2 of each of the face plates 1. By the constitution, the wooden plate member 3 is monolithically connected to the inorganic face member 2 having fire resistance, and the plate member 3 reinforces the face member 2 to form quasi-fire resisting construction.
