Description

続いて、直貼りフロアについての効果を確認するため、厚さ１．５ｍｍの化粧板（樹種：ウォルナット）を厚さ８．４ｍｍの積層木質基材層（第1層（クロス）：１．５ｍｍ、第２層（平行）：０．７ｍｍ、第３層（クロス）：１．５ｍｍ、第４層（平行）：１．２ｍｍ、第５層（クロス）：１．５ｍｍ、第６層（平行）：０．５ｍｍ）に貼り付け、さらに、厚さ４．５ｍｍの不織布を遮音層として貼り付けた床材に、化粧層１表面から４．５ｍｍの位置にサイド側雌実の上アゴ部を形成し、試験Ｎｏ．５とした。なお、積層木質基材層は、５プライ合板に１．５ｍｍのクロス単板を貼り付けたものである。得られた床材から図３に示す試験片を切り出した。試験Ｎｏ．５は、化粧層表面からサイド側雌実の上アゴ部までの間において積層木質基材層の層数が３層であり、比〔Ｈｐ／（Ｈｐ＋Ｈｃ）〕が０．４９、比〔Ｈｔｐ／（Ｈｔｐ＋Ｈｔｃ）〕が０．４６、比（Ｈ０／Ｈｔ）が０．５４と、いずれも本発明で規定される範囲内にあり、跳ね上がり量が０．１２ｍｍと許容範囲内であった。 Subsequently, in order to confirm the effect of the directly pasted floor, a laminated board having a thickness of 8.4 mm (tree species: walnut) and a laminated wooden substrate layer having a thickness of 8.4 mm (first layer (cross): 1.5 mm) , Second layer (parallel): 0.7 mm, third layer (cross): 1.5 mm, fourth layer (parallel): 1.2 mm, fifth layer (cross): 1.5 mm, sixth layer (parallel) ): 0.5 mm), and further, the upper jaw part of the side-side female fruit is placed at a position 4.5 mm from the surface of the decorative layer 1 on the floor material on which a 4.5 mm-thick non-woven fabric is attached as a sound insulation layer. Formed, test no. It was set to 5. The laminated wood base layer is a 5-ply plywood bonded with a 1.5 mm cross veneer. A test piece shown in FIG. 3 was cut out from the obtained flooring. Test No. 5, the number of layers of the laminated wood base material layer is 3 between the decorative layer surface and the upper jaw part of the side female body, the ratio [Hp / (Hp + Hc)] is 0.49, and the ratio [Htp / (Htp + Htc)] was 0.46 and the ratio (H0 / Ht) was 0.54, both of which were within the range defined by the present invention, and the amount of jump was within an allowable range of 0.12 mm.
