<p><P>PROBLEM TO BE SOLVED: To effectively prevent a floor squeaking phenomenon in a floor structure using support legs and a board-based cushioning material. <P>SOLUTION: This double floor structure has a structure to support a corner part (3a) or an edge part of a floor backing plate (3) by an upper support plate (14) of the support leg (1) arranged on a floor slab, to fix the board-based cushioning material (4) on the floor backing plate and to further fix a floor finishing material (5) on the board-based cushioning material. The board-based cushioning material is formed of a gypsum-based face material having a gypsum core material. The lower face of the gypsum-based face material is formed of an exposed surface of the gypsum core material, a surface treated coating layer of resin, a planar resin coating layer, a multipoint-like resin coating layer, an emboss-like resin coating layer, a multiple linear resin coating layer, a resin sheet, nonwoven fabric, woven fabric, or embossed paper or sheet. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
