Description

  In the present invention, when flooring is laid, the tapping sound generated at the joint of adjacent flooring is reduced, and in particular, flooring that has been subjected to actual processing is laid on the joining end surface of the wooden flooring. In particular, the present invention relates to a flooring material in which the trumbling sound at the actual joint is reduced with a simple configuration.

  Conventionally, floor materials that have been subjected to actual processing on the joint end faces are made by bringing the joint end faces of the floor materials into contact with each other on a floor base material made of plywood, etc., or an elastic sheet made of synthetic resin, etc. Laid. When walking on this laid floor, the floor is displaced up and down. In particular, this displacement is large at the actual joint, and when the actual joint is restored to its original state, the abutment surface causes relative frictional friction, and unpleasant friction sounds such as keys, cues, ghees and snaps. Wake up. That is, a so-called tapping sound is generated.

In order to solve the above-mentioned problems, conventionally, as shown in Japanese Patent Laid-Open No. 10-183964, the wooden flooring 1 has a male strip 2 or a small hole 3 on an end surface to be joined. , Male 2, small hole 3, male 2 upper end surface, small hole 3 upper end surface, male fruit 2 lower end surface, and small hole 3 lower end surface, or sliding member 4 continuously or intermittently over the entire length Even if the surface of the sliding member and the adjacent floor surface in contact with the sliding member surface or the sliding member surfaces in contact with each other rub against each other, the frictional resistance of the sliding member surface is small and almost generates frictional noise. There was no wooden flooring structure so there was no risk of trumbling.
Japanese Patent Laid-Open No. 10-183964 (first page, FIG. 2)

  However, the structure of the wooden floor material according to the conventional example is that the sliding member is provided over the entire length on at least one of the facing surfaces of the male and the small holes, the upper facing surface and the lower facing surface. Because it is interposed continuously or intermittently, it requires an extra sliding member as a separate part at the actual joint, which takes time and labor for laying the flooring, and where no sliding member is interposed Has a problem that when the person steps on the floor surface, the actual joint easily moves up and down.

  The present invention has been made in view of the above-mentioned background art, and its purpose is to make it easy to make a tapping sound at the actual joint when a floor material subjected to actual processing is laid on the joint end surface of the wooden floor material. It is in providing the flooring which can be made small by a structure.

  In order to solve the above-mentioned problem, the invention according to claim 1 of the present application is directed to a floor material in which a plurality of floor boards each having an actual machining formed on an end face are laid in a state where actual machining parts are actually coupled to each other. When the surface sheet on which the irregularities are formed is attached to the surface of the floor board, the both end sheet parts of the surface sheet are folded downward and attached to the vertical surface located at the upper part of the actual processing part of the floor board, and the floor board is laid The floor material is characterized in that minute irregularities on both end sheet portions of adjacent floor boards are brought into contact with each other.

The invention according to claim 1, wherein, in the above Kiyuka material is characterized by being configured to fine irregularities on both end sheet portion with small ridges formed on the horizontal direction.

The invention according to claim 2 of the present application is characterized in that in the flooring material according to claim 1 described above, when the floorboards are laid, the minute protrusions which are in contact with each other of the adjacent floorboards are fitted to each other.

The invention according to claim 3 of the present application is the flooring material according to claim 1 or 2 , except for the both end sheet portions of the surface sheet adhered to the vertical surface located above the actual processing portion on the surface of the surface sheet. It is characterized by having formed a coating film.

  In the flooring material of the invention according to claim 1, since the adjacent both end sheet portions of the surface sheet adhered to the vertical surface located at the upper part of the actual processing portion are in contact with each other through minute irregularities, The contact area between the sheet portions on both ends is smaller than that on the entire surface. Therefore, when a person walks on or near the floor surface on the real coupling portion, the real coupling portion is displaced in the vertical direction, causing the relative unevenness of the minute irregularities, resulting in an unpleasant frictional sound. Even when a floor noise is generated, since the contact area is small, the volume is suppressed.

In the flooring of the invention described in claim 1 , in particular, since the minute irregularities on the sheet portions at both ends are constituted by minute protrusions formed in the horizontal direction, a person steps on or near the actual coupling portion. When walking, the actual coupling portion tends to be displaced in the vertical direction, and the resistance to the vertical displacement of the minute protrusion formed in the horizontal direction is increased. Therefore, the increased resistance force suppresses the displacement, and eventually unpleasant frictional noise and floor noise are well suppressed.

In the flooring material of the invention described in claim 2 , in particular, in the flooring material of claim 1 , when the floor boards are laid, the minute protrusions that contact each other of the adjacent floor boards are fitted to each other. The contact area between the sheet portions is smaller than that of the entire surface contact, and the resistance to the vertical displacement is further increased, and the increased resistance force suppresses the displacement, resulting in unpleasant friction noise and floor noise. Sound is better suppressed.

In the flooring material of the invention according to claim 3 , in particular, a coating film is formed on the surface of the surface sheet, excluding both end sheet portions of the surface sheet attached to the vertical surface located at the upper part of the actual processing portion. As a result, the top surface of the top sheet has no or almost no micro unevenness. As a result, the top sheet surface is close to a smooth surface, and it is difficult for dust, dirt and dirt to adhere to the surface. Even if it adheres to the surface, there is an effect that it is easy to clean. Further, when the design value is higher when there is no fine unevenness due to the pattern of the surface sheet, the pattern due to the fine unevenness can be easily removed by applying a coating film. In addition, the wear resistance and strength of the surface sheet can be increased by appropriately selecting the material of the coating film.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 to 3 show a first embodiment of a flooring according to the present invention. FIG. 1 is a cross-sectional view showing a flooring, FIG. 2 is a partial cross-sectional view at an actual connecting portion of the flooring, and FIG. 3 is a partial enlarged cross-sectional view at an actual connecting portion of the flooring.

  In the figure, 1 is a floor board made of plywood obtained by laminating a plurality of wood veneers, and a male 11 is formed on each of one longitudinal end face and one short end face of the floor board 1, and the floor board 1 A female fruit 12 is formed on each of the other longitudinal end face and the other short end face. However, in the figure, only one male fruit 11 and one female fruit 12 are shown. Reference numeral 2 denotes a surface sheet, and the surface sheet 2 is made of a plastic sheet, a decorative veneer, or the like, and fine irregularities 21 (see FIG. 3) are formed on the surface by embossing or the like. On the vertical surfaces 13 and 14 located at the upper part of the actual processed portion of the floor board 1, that is, the upper vertical surfaces 13 and 14 of the male fruit 11 and the female fruit 12, the both end sheet parts 22 and 23 of the top sheet 2 are downward. It is stuck in a state where it is bent.

  As shown in the partial plan view in FIG. 5, the minute irregularities 21 are composed of minute irregularities 21 (FIG. 5A) composed of the minute protrusions 211 formed in the horizontal direction, and minute protrusions formed in the oblique direction. It is formed from minute irregularities 21 (FIG. 5B), zigzag minute irregularities 21 (FIG. 5C), geometric minute irregularities 21 (FIG. 5D), and the like. However, the shape of the minute unevenness 21 is not limited to these example shapes.

  As shown in FIGS. 2 and 3, when flooring is laid on a floor base material (not shown) made of plywood, foamed plastic sheet or the like, both end sheet portions 22, 23 of the adjacent floor plates 1, 1 are used. The upper minute irregularities 21 and 21 come into contact with each other. The contact area of the minute irregularities 21 and 21 is smaller than that in the case where the minute irregularities are not formed. Therefore, when a person walks near the actual coupling part on the floor and the actual coupling part is displaced in the vertical direction, the minute uneven part causes a relative frictional deviation and generates an unpleasant friction sound or floor noise. However, since the contact area is small, the volume is smaller than when the minute unevenness 21 is not formed.
