To provide a wooden floor fireproof floor substrate structure in which a wooden floor provided with semi-fireproof construction or fireproof construction can be simply and easily formed by using a granular material.SOLUTION: A fireproof floor substrate structure 10 is provided to be interposed between a wooden floor member 12 forming a wooden floor 11 and a floor finishing material 13 and improves fireproof performance of the wooden floor 11. The fireproof floor substrate structure is constituted to include a granular material laying layer 14 comprising granular materials 14a laid on the upper surface of the wooden floor member 12 and a floor substrate surface material 15 mounted to cover the top of the granular material laying layer 14. Frame members 16 are mounted to be partitioned horizontally and vertically on the upper surface of the wooden floor member 12, and the granular material laying layer 14 is formed by the granular materials 14a laid to be filled into each section 17 partitioned by the frame members 16.SELECTED DRAWING: Figure 4 【課題】準耐火構造又は耐火構造を備える木製床を、粒状体を用いて簡易に且つ容易に形成することのできる木製床の耐火床下地構造を提供する。【解決手段】木製床１１を形成する木床部材１２と床仕上材１３との間に介在して設けられて、木製床１１の耐火性能を向上させる耐火床下地構造１０であって、木床部材１２の上面に敷設された粒状体１４ａによる粒状体敷設層１４と、この粒状体敷設層１４の上方を覆って設置された床下地用面材１５とを含んで構成されている。木床部材１２の上面を縦横に仕切って枠部材１６が取り付けられており、粒状体１４ａは、枠部材１６によって仕切られた各々の区画１７に充填されるようにして敷設されて、粒状体敷設層１４を形成している。【選択図】図４
