PROBLEM TO BE SOLVED: To provide a woody floor material capable of enhancing sound-proofness to an impact sound, even if an impact load acts on a surface, without hindering a stepping feeling of the floor material.SOLUTION: A woody floor material 1 comprises at least a woody base material 2, an impact cushioning material 3 laminated on a reverse surface 2b of the woody base material 2 and a sheet material 4 laminated on a reverse surface 3b of the impact cushioning material 3. The sheet material 4 is formed with a plurality of projection parts 42, 42, etc. projected toward the impact cushioning material 3 side. The respective projection parts 42 are buried in the impact cushioning material 3, and the sheet material 4 is also laminated on the impact cushioning material 3 so as to form a cushioning layer 31 composed of a part of the impact cushioning material 3 between a tip part of the respective projection parts 42 and the reverse surface 2b of the woody base material 2.SELECTED DRAWING: Figure 5
【課題】床材の踏み心地を阻害することなく、表面に衝撃荷重が作用しても、衝撃音に対する防音性を高めることができる木質系床材を提供する。【解決手段】木質系床材１は、木質系基材２と、該木質系基材２の裏面２ｂに積層した衝撃緩衝材３と、衝撃緩衝材３の裏面３ｂに積層したシート材４とを少なくとも備える。シート材４には、衝撃緩衝材３側に向かって突出した複数の突起部４２，４２，…が形成されている。各突起部４２は衝撃緩衝材３に埋設され、かつ、各突起部４２の先端部と木質系基材２の裏面２ｂとの間に衝撃緩衝材３の一部からなる緩衝層３１が形成されるように、シート材４が衝撃緩衝材３に積層されている。【選択図】図５
