PURPOSE: To improve fire-proof property and sound-proof function between respective dwellings by arranging spaces between beams and floor panels separated from each other with the party wall beams, to arrange the floor panels, and by fitting fire-proof plates in the space sections.
CONSTITUTION: The respective dwellings of an apartment house are separated from each other with party wall beams, and floor panels 6, 6 are arranged. After that, the brackets 13 of the panels 6 with a reference line N through a party wall are fixed on the outer peripheral beam 4 of the panels 6 with a pair of bolt holes 14, 14 and bolts 23. Also on the frames 9 of the short piece sides of the panels 6, the brackets 13 are fixed with bolts 29. In this case, the bolts 29 are fixed to be positioned so that space sections 30 may be generated between the end sections of the party wall sides of the brackets 13 and floor beams. Then, two pieces of plaster board 32 are arranged to be vertically penetrated through the space sections 30. As a result, the fire-proof plates 30 are not separated from each other at the floor beam sections, and fire-proof property and sound-proof property can be improved.
