Description of the Related Art As a conventional wooden flooring material of this type, as shown in FIG. 4, a non-woven fabric, a fiber mat, an open-celled synthetic material are formed on the lower surface of a wooden board (2). A wood floor material (11) to which a breathable cushioning member (3) made of resin foam or the like is joined is known. This wood flooring
According to (11), when an external force such as an impact is applied to the surface of the floor material (11), the air present in the voids of the cushioning member (3) moves in the horizontal direction and the Since the compression deformation is performed smoothly, excellent cushioning properties and sound insulation properties can be obtained even when the cushioning member (3) is relatively thin.

照）。However, the above-mentioned wooden floor material (11) is a floor base material such as concrete slab or particle board.
When the work adhesive (A) is directly attached to (B), the work adhesive (A) penetrates into the voids of the cushioning member (3) and solidifies to reduce the compressive deformation portion of the member (3). As a result, there is a problem that the buffering property and the sound insulating property are deteriorated (see FIG. 4).

Since it is necessary to line them up, for the second and subsequent rows, first the wooden floor material (11) is already placed at the proper position on the floor base material (B) coated with the construction adhesive (A) ( After placing it temporarily with a little space next to (11) (see Fig. 5 (a)), slide it sideways and fit the male (2a) and female (2b) of both floor materials (11). They are matched (see Fig. 5 (b)). However, in the case of the above wooden floor material (11), the wooden board (2)
Even if is pressed, the construction adhesive (A) penetrates into the voids of the cushioning member (3) to increase the adhesion with the floor base (B), and the cushioning member (3) easily elastically moves in the lateral direction. Because of deformation, it is difficult to shift to the proper position, and in some cases, these male (2a) and female (2b) can be left with a gap between the cushioning members (3) of both floor materials (11). ) May be fitted together (see FIG. 5 (b)). Then, the cushioning member (3) that has been elastically deformed in the lateral direction is restored, and the male fruit (2a) and the female fruit (2b) that have been fitted may be separated from each other (Fig. 5). (See (c)).

As shown in (1), a wooden floor material (12) has been proposed in which the independent foaming synthetic resin foam sheet (5) is joined to the lower surface of the cushioning member (3). According to this wood floor material (12), the presence of the independent foaming synthetic resin foam sheet (5) makes it possible to use the adhesive for construction.
It is possible to prevent (A) from penetrating into the cushioning member (3), and thus it is possible to avoid the deterioration of cushioning and sound insulation due to the bonding work, but since the thickness of the sheet (5) increases, There is a problem that the amount of subsidence during walking increases and the feeling of walking deteriorates.

避けられない。Further, as shown in FIG. 7, a flexible plastic film such as polyethylene is formed on the lower surface of the cushioning member (3).
A wood flooring material (13) obtained by joining (6) has also been proposed (see Japanese Utility Model Laid-Open No. 4-90628 and JP-A-6-336814). According to this wood floor material (13), due to the presence of the plastic film (6), the construction adhesive (A) is a cushioning member.
It is possible to prevent it from penetrating into (3), and the amount of depression during walking does not become large unlike the wooden flooring material (12) shown in FIG. 6, and there is no problem in walking feeling. However, since the surface of the plastic film (6) is very smooth, the wooden flooring (1
3) is easy to skid on the floor base (B), and adjacent wooden floor materials
(13) Not only can there be gaps between them, but the anchoring effect can hardly be expected, so the adhesion is poor and the wood flooring (13) peels off after the construction adhesive (A) solidifies. There were things. And as a means for solving such a problem, there is a method of subjecting the plastic film (6) to corona discharge treatment (Actual Publication No. 4-90628).
The effect of improving the adhesiveness by corona discharge treatment lasts only about 1 to 3 months at the most, and the period from the production of the wooden floor material (13) to the construction is significantly limited, so it is not necessarily an effective means. . It is also possible to use a plastic film (6)
A means for partially joining (6) to the lower surface of the cushioning member (3) has also been proposed (Japanese Utility Model Laid-Open No. 4-90628, etc.), but in that case, the through hole of the plastic film (6) or the plastic film Since the construction adhesive (A) penetrates into the cushioning member (3) and solidifies through the part where (6) is not joined,
Along with that, a decrease in the cushioning property and sound insulation of the wooden floor material (13) is unavoidable.

示することができる。C. Construction adhesive permeation prevention member The construction adhesive permeation prevention member (4) has a large number of voids (not shown) on its lower surface so that the anchoring effect due to the penetration and solidification of the construction adhesive (A) can be obtained. When it is placed on the floor base (B) through the uncured construction adhesive (A) layer, it has enough rigidity that it can be laterally displaced by pushing its edge (4a). If it is, it is not particularly limited,
For example, when a plastic film or a material obtained by joining a nonwoven fabric or the like to the lower surface of the plastic film is used, the rigidity of the plastic film is obviously inferior and the effect of the present invention cannot be achieved. Examples of the material of the construction adhesive permeation prevention member (4) include the following.

られる。The first group includes a hard synthetic resin sheet (41) to which an adhesive penetrating material (42) is bonded to the lower surface (see FIG. 1). The hard synthetic resin sheet (41) can reliably prevent the adhesive for construction from penetrating into the cushioning member (3) and is lightweight, low in cost and economical, but has a smooth surface and good adhesiveness. There is a problem that it is inferior, but a material (4
By joining 2), a large number of voids are formed so that the anchoring effect can be obtained by the penetration and solidification of the construction adhesive (A), so that there is no problem in terms of adhesion. In manufacturing this, considering that the adhesiveness of the hard synthetic resin sheet (41) is not good, the cushioning member (3), the hard synthetic resin sheet (41) and the material having adhesive permeability (42) It is considered that a means for previously integrating and by heat fusion or the like is preferable. Examples of the material of the hard synthetic resin sheet (41) include non-foam or foam such as polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyurethane, polyethylene terephthalate, and methyl methacrylate. Here, it is preferable that the foam has an expansion ratio of 3 times or less, more preferably 2 times or less. This is because if the expansion ratio exceeds 3 times, sufficient rigidity cannot be obtained. The material having adhesive permeability (42),

When it is placed on the floor base (B) via the uncured construction adhesive (A) layer, the edge (4a) can be pushed to the side where it can be displaced laterally. I wish I had it. Specifically, when the member (4) is made of the material of the first group, the hard synthetic resin sheet (41) has a thickness of 0.3 to 2.0.
mm, preferably 0.5 to 1.0 mm, and the thickness of the adhesive permeable material (42) is 0.035 to 2.0 m.
m, preferably 0.05 to 1.0 mm. With respect to the hard synthetic resin sheet (41), if the thickness is less than 0.3 mm, it is not possible to obtain rigidity enough to achieve the above effect, and as the thickness is increased, the rigidity is increased and a hard hand is obtained. However, considering the overall thickness and weight of the wooden flooring (1) and the economical efficiency, it is appropriate that the thickness is 2.0 mm or less. Further, regarding the material (42) having adhesive permeability, when the thickness is less than 0.035 mm, the adhesive
The penetration depth of (A) is too shallow to obtain sufficient anchoring effect. On the other hand, when the thickness exceeds 2.0 mm, an elastic layer that does not solidify the adhesive (A) is formed and the sound insulation is improved, but the elastic layer is elastically deformed during construction. This is because it becomes difficult to laterally shift the wooden floor material (1), or the amount of subsidence during walking increases due to the influence of the same layer, which deteriorates the feeling of walking. If the material (42) having adhesive permeability is a non-woven fabric, the basis weight is 1
5-110 g / m2 is considered suitable. Further, when the construction adhesive permeation preventive member (4) is made of the material of the second group, the thickness is usually 1 to 3 mm, though there is some variation depending on the type.

かせるような懸念もない。EFFECTS OF THE INVENTION According to the wood flooring material of the present invention, the presence of the adhesive permeation preventive member for construction does not cause a decrease in the cushioning property and the sound insulation due to the construction.
After temporarily placing it on the floor base to which the adhesive for construction has been applied, it is possible to easily shift the parts horizontally and fit the fitting parts of the wooden floor material together. There is no skidding and the amount of depression when walking is not so great, so the feeling of walking is not impaired.
Furthermore, there is no concern that it will make consumers and contractors feel uneasy when held in their hands.
