WOODY FLOOR MATERIAL AND FLOOR STRUCTURE
PROBLEM TO BE SOLVED: To provide a direct-sticking woody floor material excellent in sound insulation performance.SOLUTION: The present invention aims at a woody floor material having a plywood base material layer 1 constituted of plywood made by laminating a plurality of veneer sheets 11-15, a decorative layer 2 provided on the surface side of the plywood base material layer 1 and a sound insulation layer 3 provided on the reverse surface side of the plywood base material layer 1, and constructed by direct sticking. In the plywood base material layer 1, a plurality of rear grooves 4 extending in a floor material width direction and opening on the reverse surface side are formed at an interval in the floor material length direction. An upper end position of the rear groove is arranged in a veneer sheet 12 of a second layer from above in the plywood base material layer 1. A thickness of the veneer sheet 11 of a first layer among the plurality of veneer sheets 11-15 for constituting the plywood base material layer, is set to 0.2 mm-0.8 mm. The sound insulation layer 3 is constituted of at least any one of a synthetic resin foam body and synthetic fiber nonwoven fabric, and a thickness of the sound insulation layer 3 is set to 2 mm-6 mm.SELECTED DRAWING: Figure 2
【課題】遮音性に優れた直貼り用の木質系床材を提供する。【解決手段】本発明は、複数の単板１１〜１５が積層された合板によって構成される合板基材層１と、合板基材層１の表面側に設けられた化粧層２と、合板基材層１の裏面側に設けられた遮音層３とを備え、直貼りで施工される木質系床材を対象とする。合板基材層１に、床材幅方向に延び、かつ裏面側に開放する裏溝４が、床材長さ方向に間隔をおいて複数形成される。裏溝の上端位置が、合板基材層１における上から２層目の単板１２内に配置される。合板基材層を構成する複数の単板１１〜１５のうち、１層目の単板１１の厚みが０．２ｍｍ〜０．８ｍｍに設定される。遮音層３が、合成樹脂発泡体および合成繊維不織布のうち少なくともいずれか一方によって構成されるとともに、遮音層３の厚みが２ｍｍ〜６ｍｍに設定されている。【選択図】図２
