ｒ、版厚１５０鶴にて測定した。Carpet has traditionally been the mainstream floor covering material for apartment complexes. However, recently, wood-based floor finishing materials have begun to be reconsidered due to complaints about hygiene, such as carpets being prone to dust mites, and the lack of a natural feel. However, when this wood-based finishing material is used as a floor finishing material for condominiums, it has a major drawback of poor floor impact sound insulation properties. In other words, floor impact sounds (light floor impact sounds) such as footsteps and the sound of objects being dropped from upstairs are transmitted downstairs,
There were noise complaints. Therefore, a method was developed in which a foamed plastic was pasted on the back side of the wooden floor finishing material in an attempt to deal with lightweight floor impact noise, but its sound insulation performance did not meet the required level (L-55 for lightweight impact sources). It was something. In order to satisfy this required level, it was necessary to make the foamed plastic layer applied to the back side of the finishing material about 6 to 15 mm thick. A finishing material provided with such a foamed buffer layer of about 6 to 15 m has the disadvantage that the floor surface becomes soft and easily dented, causing floor noise. As a typical conventional wood-based floor finishing material, the wood layer 101 is 71 m thick, the buffer layer 102 is 8 fi, and the total thickness is 15 m.As a result of measuring the floor impact sound blocking performance, it was found that The grade was L-65. The density of the flooring (concrete slab) is 2.3t/rr.
Measured using a plate with a thickness of 150 mm.

２の裏面に緩衝層１０３を形成したものである。Therefore, the present inventor previously developed a floor finishing material as shown in FIG. 15. A damping/sound insulating layer 101 is formed on the back side of a surface finish material 100 made of a relatively hard material such as wood or synthetic resin, and a support such as veneer plywood is formed on the back side of this damping/sound insulating layer 101. Attach the plate 102, and this support plate 10
A buffer layer 103 is formed on the back surface of 2.

れた性能を出すことが出来なかった。The buffer layer 103 in the floor finishing material shown in Fig. 15 uses a sheet-like elastic material with smooth upper and lower surfaces. It was not possible to reduce the target spring constant to less than 15 kg/cm-cr1. On the other hand, in order to improve the lightweight impact sound isolation characteristics, it is necessary to further lower the spring constant of the buffer layer 103, and as long as the sheet-shaped buffer layer 103 with the shape shown in FIG. 15 is used, the sound insulation grade is L- It was not possible to achieve excellent performance of 60 or higher.

The purpose is to provide floor finishing materials with excellent performance.

緩衝層を形成したものである。In order to achieve the above-mentioned object, the present invention forms a vibration damping/sound insulating layer on the back side of a surface finishing material made of a relatively hard material such as wood or synthetic resin. A support plate such as veneer plywood is attached to the support plate, and a buffer layer is formed on the back surface of this support plate, the upper and/or lower surfaces of which are not smooth but have an uneven surface.
