Description

[Detailed description of the invention] (Industrial application field) TECHNICAL FIELD The present invention relates to flooring materials for laying.

(Prior art) Recently, some fiber carpeted floors or tatami matted floors have been used as a flooring material to replace the entire surface with wood flooring, and the surface of the backing sheet is made of decorative plywood. A flooring material for flooring in which unit plate-shaped bodies are arranged side by side and fixed together has been proposed.

As such a flooring material, for example, a plate-shaped surface board such as decorative plywood is attached to a backing notebook made of cloth, synthetic resin sort, etc., and then slit-like grooves are carved in parallel at predetermined intervals only on the surface board. Flooring material separated into narrow band-shaped unit surface plates (1986)
2-94235), or a flooring material in which strip-shaped wooden surface boards are arranged in parallel on a soft synthetic resin sheet and adhered to the resin notebook (see Utility Model Application Publication No. 63-47775). There is.

(Problem to be solved by the invention) However, since the former flooring material has a large number of slit-like grooves in the wood decorative board layer, there is a risk that clothes, etc. may get caught in some of the corners of the groove edges. However, there was a problem that it lacked suitability as a flooring material.

On the other hand, in the case of the latter type of flooring, it is difficult to arrange the wooden planks closely together during production, often creating gaps between the planks. When arranging the plate-shaped bodies, it is necessary to perform operations such as rearranging or recombining them, or even pushing them together to reduce the distance between adjacent plate-shaped bodies, depending on the color difference of the decorative surface. However, since the resin sheet and plate-shaped body are integrated using adhesive, the above operations are extremely difficult, and
The retention rate of good products is low because there is a risk of contaminating the plate with adhesive, and furthermore, even if you try to prevent warping or twisting by adjusting the moisture content of the plate, the use of adhesive Therefore, there were problems such as it being difficult to completely eliminate the occurrence of deformation of the plate-shaped body and deformation of the entire floor.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a flooring material that eliminates the drawbacks of the prior art as described above and also has a soundproofing effect.

(Means for Solving the Problems) The present invention provides a plurality of hook-like structures that extend along both side edges of the back surfaces of a plurality of adjacently arranged unit plate-like bodies, straddling between two unit plate-like bodies. A hook-and-loop fastener having a (or loop-shaped) engaging element is attached to connect a plurality of unit plate-like bodies, and the hook-shaped (or loop-shaped) engaging element is attached to the back surface of the connected unit plate-like body. This flooring material is characterized in that a backing sheet having loop-shaped (or hook-shaped) engaging elements to be joined is joined and integrated.

(Function) The flooring material for flooring according to the present invention uses a hook-and-loop fastener instead of an adhesive to connect the unit plate-shaped body and the sheet, so there is no deformation of the flooring material, and the yield rate of good products can be improved. can. Furthermore, the large dynamic damper effect created by the large number of fine gaps formed by the loop-shaped engagement elements improves the soundproofing performance against floor impact sounds.

(Example) Next, an example of the flooring material of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of the flooring material, and FIG. 2 is a back view of a plurality of connected unit plate bodies.

As shown in FIG. 1, the flooring material of the present invention has a sheet 1 having loop-shaped engagement elements used as a backing sheet, and a sheet 1 that is arranged in parallel in close contact with each other on the backing sort 1. A plurality of unit plate-like bodies 2 and a plurality of unit plate-like bodies 2 are connected to each other, and the unit plate-like bodies are connected to a backing sheet 1.
It is composed of a hook-and-loop fastener 3 having a hook-like engagement element that is joined and integrated with the hook-like engaging element.

The unit plate-shaped body 2 is generally made of decorative wood plywood with a decorative veneer 2a adhered to the surface, but other materials such as particle board, hard board, medium-density paper I board (MDF), and inno-rayon board are also used. , wafer board, oriented solid board (OSB), veneer laminate (LVL)
), :] In addition to wood boards such as luku wood, phenolic resin boards,
A hard synthetic resin board such as an acrylic resin board, or even a hard synthetic resin foam board, etc. may be used. The size of the unit plate-like body is 10 to 500 cm in diameter, 3 to 10 mm in thickness, and 3 in length.
00■ or more. Further, in the case of a rollable flooring material as shown in FIG. 6, a narrow band-like material having a width of 900+avX 60 mm is used, for example. The unit plate-like body may be a single plate as shown in FIG. 1, or a plurality of narrow plate-like bodies 2-1 to 2-5 as shown in FIG. ) may be an integrated board. Usually, a square-shaped unit plate of 450 mm x 450 am, for example, is used. It is preferable that the upper edges of both sides of the unit plate-like bodies are chamfered so that shallow grooves, such as a 7-shaped groove, can be formed between adjacent unit plate-like bodies when the unit plate-like bodies are laid. Further, both side surfaces 4 including the chamfered portion 4a are preferably colored in the same or similar color tone as the decorative surface of the decorative veneer 2a.

It is attached along both side edges of the back surface of the unit plate-like body 2, spanning between two unit plate-like bodies, connects a plurality of unit plate-like bodies, and has a loop-shaped engagement element to be described later. The hook-and-loop fastener 3, which has a hook-like engaging element that joins and integrates the plate-shaped body with the backing sort, is an integrally molded plastic hook-and-loop fastener obtained by a molding method such as plastic extrusion, or a tiA weave of filament fibers. Woven fasteners are used. The hook-shaped engaging element forming such a hook-and-loop fastener may have any shape as long as it can be easily engaged with the loop-shaped engaging element, and may be hook-shaped, mushroom-shaped, arrowhead-shaped, umbrella-shaped, or the like. The height of the hook-shaped engagement element is usually 0.
．． 5 to 3 mm, preferably 1.5 to 3 mm is suitable. If the height of the hook-shaped engagement element is high, there is a risk that the engagement element will deform when an impact load is applied to the upper part of the flooring, causing the flooring to shift.

One end side of the hook-and-loop fastener is attached along the edge of the back surface of the unit plate-like body 2, and the other end side is attached along the edge of the adjacent unit plate-like body by chemical bonding means such as adhesive, high frequency, It is attached to the back surface of the unit plate-like body by using heat bonding means such as ultrasonic waves and heating, and physical bonding means such as nails, screws, and tackers, either alone or in combination. Glue is usually used. Hook-and-loop fasteners are used to connect connected unit plate-like bodies to a backing sheet, as shown in Figure 3 (the back side of the connected unit plate-like bodies shown in Figure 2). It can be attached not only across both end portions, but also around the outer periphery of the connected unit plate-like bodies. In order to improve the bonding strength with the backing sheet, a hook-and-loop fastener may be attached to an area other than the above on the back surface of the unit plate-like body.

In addition, since the thickness of the flooring material is different between the area where the hook-and-loop fastener is attached and the other area of the unit plate-like body, there is a risk that the flooring material will sink when walking on a thin plate-like body. Therefore, in the case of thin plate-like bodies, the unit plate-like bodies are connected by pasting a thickness adjustment sheet 5, such as a non-woven fabric with adhesive, on the area where the hook-and-loop fastener is not attached, as shown in FIG. The thickness of the hook-and-loop fastener may be made constant, or a groove 6 equal to the thickness of the hook-and-loop fastener may be provided in advance at the side end portion of the back surface of the unit plate-like body, as shown in the cross-sectional view of FIG.

The backing sheet 1 of the connected unit plate-shaped bodies is a sheet having a loop-shaped engagement element that engages with the hook-shaped engagement element, and has a sufficiently large engagement force with the hook-shaped engagement element, and can be repeatedly detached. A nonwoven fabric or knitted fabric with a thickness of 2 to 15 mm, for example, is used, which has excellent shape retention and does not sink when walking. Among them, 50% or more of polyester fibers of 8 denier to 15 denier, hollow polyester fibers of the same denier as the polyester fibers 2
0-40% and polyester heat-fusible fiber 10-3
A needle-punched nonwoven fabric containing 0% cotton is preferably used.

The backing notebook 1 may be only a sheet containing the above-mentioned loop-shaped engagement element, or may be a notebook in which the sheet and a synthetic resin notebook are bonded together. The latter type of backing notebook is usually preferred.

When bonding a nonwoven fabric or the like to a synthetic resin notebook, it is preferable to impregnate or coat the adhesive surface of the nonwoven fabric with a resin in order to strengthen the adhesive force.

As the synthetic resin notebook, a soft vinyl chloride sheet, a foamed rubber sheet, etc. with a thickness of 1 to 2 mm is used. In addition, the surface in contact with the bedding surface is provided with a partial or continuous uneven shape,
It is preferable to prevent slipping on the bedding surface.

In addition, in the above description, an example was explained in which a hook-and-loop fastener having a hook-shaped engagement element is attached to the back surface of a unit plate-like body, but a hook-and-loop fastener having a loop-like engagement element may be attached to the back surface of a unit plate-like body. . In that case, it is necessary to attach a hook-and-loop fastener having a hook-like engagement element to the backing notebook to be joined with the connected unit plate-like bodies.

(Effects of the Invention) As described above, the flooring material of the present invention can be easily laid down in the same way as fiber carpet to form a desired wooden floor, etc. It does not deform, has better soundproofing against floor impact noise than conventional flooring materials, and can be provided at low cost with a high yield of good products.
