れている。（例えば実公昭63−20764号公報参照）。<Problems to be Solved by Conventional Techniques and Inventions> Conventionally, flooring base materials for concrete houses made of synthetic resin foam have been widely used as an alternative to conventional joist. A floor base material having a structure for facilitating nailing or adhesion of the floor material has been proposed and put into practical use. (See, for example, Japanese Utility Model Publication No. 63-20764).

を特徴としている。<Means for Solving the Problems> As a constitution of a floor base material according to the present invention which can solve the above problems, a plurality of grooves are formed on the surface of a plate-like body made of a synthetic resin foam and the bottom of the grooves is formed. A soft sheet is embedded freely on the side, and a member that can be nailed or glued is joined to the upper side of the soft sheet so that it can be moved vertically in the groove and freely embedded. Is characterized in that a part thereof is formed to have a thickness capable of protruding from the upper surface of the plate-shaped body.

On the other hand, when an impact is generated downwards by a child's splashing, moving furniture, or walking, the nailable or bondable member of the floor base material moves downward in the groove, but the movement is on the groove bottom side. The soft sheet that is joined to the shock absorber absorbs and alleviates the impact, and the impact sound is also absorbed by the soft sheet portion, and the sound insulation is greatly enhanced.

分への衝撃音伝播を防止できる作用が顕著である。In the above-mentioned configuration, the soft sheet is formed so that the member capable of nailing or adhering is formed to have a thickness larger than the thickness of the member protruding from the upper surface of the plate-like member, and the movement of the member downward when shocked is mitigated. It is convenient because even if impact pressure is applied to the position where the floor material comes into contact with the upper surface of the floor base material, it is still possible to retain the absorbency, and the effect of preventing the propagation of impact sound to other parts is remarkable. Is.
＜実施例＞ 次に、この考案の実施例について、図を参照しながら
以下に説明する。<Embodiment> Next, an embodiment of the present invention will be described below with reference to the drawings.
第１図〜第３図に示す場合の床下地材の主材となる板
状体10はポリスチレン発泡体による成形品で、例えばビ
ーズ成形による40倍発泡成形品である。The plate-like body 10 as the main material of the floor base material in the case shown in FIGS. 1 to 3 is a molded product of polystyrene foam, for example, a 40-fold foam molded product by bead molding.
11は板状体10の表面に形成してある複数の溝、図では
３本の溝である。12はこれらの溝11の底側に押縮自由に

レン発泡体による合成木材によるものである。Reference numeral 11 denotes a plurality of grooves formed on the surface of the plate-shaped body 10, and three grooves in the figure. Reference numeral 12 denotes a soft sheet which is embedded in the bottom side of these grooves 11 so as to be freely compressed, and is, for example, a polyethylene foam sheet formed by 30 times expansion. Reference numeral 13 denotes a member that can be nailed or adhered (hereinafter referred to as a nailing member) that is joined to the upper side of the soft sheet 12 and is embedded in the groove 11 so as to be vertically movable. It is made of synthetic wood made of polystyrene foam.
上記した軟質のシート12および釘打ち部材13は、複数
の板状体10,10…にわたる長尺に形成して実施される場
合もある。The above-described soft sheet 12 and nail driving member 13 may be formed by being formed into a long length extending over a plurality of plate-shaped bodies 10, 10.
なお、軟質のシート12が溝11内を押縮自由にしている
ことや、釘打ち部材13が溝11内を上下に移動自由にして
いることは、何れも溝11の側面との間に隙間を有するか
摺動可能な状態になっていることを意味し、溝11の側面
とは接着されていないものである。It should be noted that the fact that the soft sheet 12 allows the inside of the groove 11 to be freely compressed and that the nailing member 13 allows the inside of the groove 11 to move freely up and down means that there is a gap between the groove 11 and the side surface. Means that the groove 11 is provided or is slidable, and is not bonded to the side surface of the groove 11.
第４図および第５図中、20は、床材を示している。 In FIG. 4 and FIG. 5, 20 indicates a floor material.
上記軟質のシート12としては、先に例示のほか、ゴム
シート、布帛シート等、衝撃緩和と音伝播性と低い材質
のものが適し、釘打ち部材13としても合成木材のほか、
天然木その他によるものでもよい。As the soft sheet 12, other than those exemplified above, a rubber sheet, a fabric sheet, or the like, which is made of a material having low impact relaxation and sound propagation, is also suitable as the nailing member 13, in addition to synthetic wood,
It may be made of natural wood or the like.

以上の厚みに形成している。ただし、床の施工面積やシ
ート12の材質等によって圧縮量は一律にはならないの
で、それらを考慮して適当な厚みに形成する。The thickness of the soft sheet 12 in the groove 11 may be set so that the floor material 20 does not come into contact with the plate-shaped body 10 when a load is applied to the sheet 12 and the sheet 12 is compressed. Normally, such a sheet 12 is compressed to about 2 to 3 mm, so that the sheet 12 is formed to have a thickness larger than that. However, since the amount of compression is not uniform depending on the construction area of the floor, the material of the sheet 12, and the like, it is formed with an appropriate thickness in consideration of them.
また、釘打ち部材13の厚みは、シート12に重ねた状態
で、上記のように床材20が板状体10との間に２〜3mm以
上の間隔を保持することができるように設定されてい
る。Further, the thickness of the nailing member 13 is set so that the floor material 20 can maintain a space of 2 to 3 mm or more between the floor material 20 and the plate-shaped body 10 as described above in a state of being stacked on the sheet 12. ing.
＜実験例＞ この衝撃音の伝播性防止効果は、以下の実験測定結果
