Description

  The present invention relates to a flooring material in which a base material is made of a wood material, and the flooring material adjacent to the flooring material is joined at side end portions.

  In general, the floor material is formed with a downward slope at the surface corners of the side edges, so that moisture and wax can easily enter the V-shaped design grooves formed between the floor materials during cleaning. Become. The surface of the flooring material including the descending slope surface is painted or pasted with an olefin sheet to achieve water resistance and wax resistance, but the butt joint surface at the side end is exposed at the end, There is a risk that moisture or the like that has entered the design groove reaches the butt joint surface and enters the base material from there. In particular, when a gap is formed between the butt joint surfaces, the intrusion of moisture or the like becomes significant.

  Conventionally, in order to prevent such intrusion of moisture and the like from the butt joint surface, a floor material is proposed in which the butt joint surface is waterproofed with a resin sealing material (see Patent Document 1). . This resin sealing material is in the form of liquid, paste or sheet, and covers the butt joint surface by coating or pasting. In the flooring of Patent Document 1, a resin sealing material is applied or pasted on the butt joint surface that continues below the descending inclined surface.

JP 2009-52244 A

  However, the waterproof treatment with the resin sealing material on the butt joint surface can be easily performed, but it is likely to deteriorate or peel off over time, and there is a possibility that moisture or the like may enter the wood portion. Further, moisture or the like may enter from a slight portion between the descending inclined surface and the butt joint surface. Furthermore, since such a waterproofing treatment is only for the surface, once moisture or the like enters, the moisture or the like may further penetrate into the inside of the base material. When moisture or the like soaks into the base material in this way, the side edges of the flooring may swell or warp on the surface side.

  In addition, when the substrate is made up of particle boards, it has a higher density that contains more resin in the adhesive than general (low cost) materials in order to prevent moisture from entering and penetrating into the substrate. It is necessary to use a board, which naturally increases the production cost.

  The present invention has been proposed in view of such circumstances, and its purpose is to allow moisture and the like to enter and penetrate into the inside of the base material made of a wood material from the side end. It is to provide a flooring that can be minimized.

  In order to achieve the above object, the flooring material of the present invention is a flooring material in which the base material is made of a wood material, and the flooring material adjacent to the flooring material and the side edge parts are joined to each other. A descent inclined surface formed by chamfering the corner of the rim, and a butt joint surface connected to the descent inclined surface, and a resin material is embedded in a portion extending inward in the lateral direction of the base material from the butt joint surface It is characterized by.

  In this invention, it is good also as a structure by which the particle board is distribute | arranged to the site | part which equipped the resin material of the base material at least.

  In the present invention, the resin material may be composed of an elastomer molded plate material.

  According to the flooring of the present invention, since it has the above-described configuration, it is possible to minimize the intrusion and penetration of moisture and the like from the side end into the inside of the base material made of the wood material. Thereby, it is possible to prevent swelling and warping of the side end portions at the joint portion between the floor materials. In addition, since the entry and penetration of moisture and the like are prevented by simple means, the production cost can be reduced.

It is a longitudinal cross-sectional view of the flooring which concerns on one Embodiment of this invention. (A), (b) is the principal part longitudinal cross-sectional view which showed the joining of the flooring, and the fixed structure (joining procedure). (A)-(c) is the principal part longitudinal cross-sectional view which showed the joining by the flooring which concerns on other embodiment, and a fixed structure.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 1 and FIGS. 3A to 3C, floor materials according to various embodiments described below are made of a base material 10 made of a wood material, and adjacent floor materials 1 and side edges. 1a and 1a are joined together. The side end portions 1a and 1a include descending inclined surfaces 25 and 35 formed by chamfering corners on the surface side, and butt joints 26 and 36 connected to the descending inclined surfaces 25 and 35, and butt joint surfaces. Resin materials 27 and 37 are provided in portions extending from 26 and 36 inward in the lateral direction of the substrate 10.

Next, the flooring 1 according to these embodiments will be described in detail individually.
1 and 2 are explanatory diagrams of a flooring according to an embodiment of the present invention.

  The flooring 1 is formed by attaching a base material 10 to a particle board and attaching a decorative material 11 to the surface of the base material 10. In addition, as the base material 10, you may use various woody materials, such as a plywood and MDF. The decorative material 11 is made of a veneer, a printing paper, an olefin sheet, and the like, and a waterproof coating film is formed on the surface of the flooring 1 including descending inclined surfaces 25 and 35 described later.

  The flooring 1 is provided with a protruding male part 20 at one side end 1a in at least one side end parts 1a, 1a in one direction, and a groove-like female real part 30 at the other side end part 1a. ing. As described above, the flooring 1 has a shape that can be fitted between the flooring 1 adjacent on the floor base 3 and the side ends 1a and 1a. In addition, the floor material by which the real part was formed in the four circumferences by providing the male real part and the female real part also in the both-sides edge part in another direction may be sufficient.

  The male part 20 of the flooring 1 has a plate shape extending outwardly so as to be parallel to the surface of the flooring 1, and the upper and lower corners (at both ends in the thickness direction of the flooring 1) are It is chamfered. A nailing groove 20 a for nailing and fixing the flooring 1 to the floor base 3 is formed on the upper surface of the male part 20.

  At the side end portion 1a on the male part 20 side, an upper notch 21 is formed on the upper side of the male part 20, and the inner side of the base material 10 extends in the lateral direction along the upper surface of the male part 20 from the upper notch 21. A concave groove is formed by cutting at an acute angle so as to extend in the direction. This concave groove is an adhesive reservoir 23 that accumulates an excess of an adhesive (not shown) for bonding the floor materials 1 and 1 to each other. On the upper side of the adhesive reservoir 23, a ridge 24 that can be butt-joined with the side end 1a on the female real part 30 side is formed. A lower notch 22 is formed below the male part 20. The upper notch 21 is cut deeper inward in the lateral direction than the lower notch 22.

  On the other hand, at the side end portion 1a on the female real part 30 side, the female real part 30 is formed in a concave groove shape that can be fitted to the male real part 20, and an upper protrusion 31 is formed on the upper side thereof, On the side, a lower protrusion 32 is formed.

  As shown in FIGS. 1 and 2, the flooring material 1 in this example is configured to butt-join between males and females over the entire length of the thickness, but the upper part (upper protruding part 31, protruding part) Only 24) may be configured to butt-join. That is, in the state in which the floor materials 1 and 1 are connected to each other, the front end of the male part 20 and the back end of the female part 30, or the bottom end of the lower notch 22 and the end end of the upper protrusion 31. It may be such that a gap is formed between the two.

  Moreover, the corner | angular part of the surface side of any side edge part 1a, 1a of the male real part 20 side and the female real part 30 side is chamfered, and the fall inclination surfaces 25 and 35 are formed. These descending inclined surfaces 25 and 35 form V-shaped design grooves by joining the floor materials 1 and 1 to each other. A coating film is formed on these descending inclined surfaces 25 and 35, and the culvert due to cutting does not appear.

  The butt joint surface 26 which is perpendicular to the surface of the flooring 1 so as to be connected to the lower inclined surfaces 25 and 35 at any of the side end portions 1a and 1a on the male real portion 20 side and the female real portion 30 side. , 36 are formed. That is, a butt joint surface 26 is formed at the end of the ridge 24 at the side end 1a on the male real part 20 side, and a butt joint at the end of the upper protrusion 31 at the side end 1a on the female real part 30 side. A surface 36 is formed. As described above, since the adhesive reservoir 23 made of a concave groove is formed at the side end 1a on the male part 20 side, the butt joint surface 26 of the ridge 24 in the thickness direction of the flooring 1 is formed. The length dimension is smaller than the length dimension of the butt joint surface 36 of the upper protrusion 31.

  In each of the protrusion 24 and the upper protrusion 31, plate-like resin materials 27 and 37 are embedded in portions extending from the butt joint surfaces 26 and 36 inward in the lateral direction of the base material 10 so as to be parallel to the surface. It is. The end surfaces on the real part side of the resin materials 27 and 37 are exposed as part of the butt joint surfaces 26 and 36. In addition, the resin materials 27 and 37 are formed on the surface of the flooring 1 at a position within 5.5 mm from the surface above the real part in consideration of the penetration force in the wood material (particle board) such as moisture. It is desirable to be arranged so as to be substantially parallel to The arrangement positions of the resin materials 27 and 37 in the thickness direction of the flooring 1 are preferably positions where the flooring materials 1 and 1 are butt-joined to each other so that the resin materials 27 and 37 are in close contact with each other. More preferably, the end portions 1a and 1a have the same position.

  The resin materials 27 and 37 are formed of an elastomer molded plate material. A concave groove is formed in advance on each of the protruding portion 24 and the upper protruding portion 31, and the base material 10 may be formed by press-fitting the resin materials 27 and 37 into the concave groove. Further, the base material 10 may be formed by injecting liquid rubber, an adhesive, or a sealing material into the concave groove and curing it. Various materials can be applied as the resin materials 27 and 37. Use of resin materials 27 and 37 made of an elastomer molded plate material is desirable in terms of ease of molding the flooring 1.

  By disposing the resin materials 27 and 37 in the base material 10 as described above, the resin materials 27 and 37 are disposed on two opposite sides or four sides of the floor material 1. In addition, even if it is the flooring 1 in which a real part is formed only in the both-sides edge part 1a, 1a of one direction, the resin materials 27 and 37 are only in the one-sided edge part 1a, 1a in which the real part was formed. In addition, it is desirable to be disposed also on the butt joint surfaces at both end portions in other directions where the real part and the descending inclined surfaces 25 and 35 are not formed. That is, it is desirable that the resin materials 27 and 37 are disposed around the floor material 1. In addition, the floor material provided with the resin materials 27 and 37 on all four sides is formed in advance by forming a rectangular ring-shaped resin material suitable for the shape of the floor material, and fitting the floor material body into the ring-shaped resin material. May be formed.

  Thus, since the resin materials 27 and 37 are embedded inward in the lateral direction from the butt joint surfaces 26 and 36 of the side end portions 1a and 1a, the butt joint surfaces 26 and 36 are provided via the descending inclined surfaces 25 and 35. It is possible to prevent moisture and wax that have entered between the intrusion from the mouth. Even if there is a gap between the butt joint surfaces 26 and 36, it is possible to prevent moisture and the like from entering from the butt joint surfaces 26 and 36. In addition, since the resin materials 27 and 37 are provided substantially parallel to the surface of the floor material 1 in the upper layer of the real part, even if moisture or the like enters, it is possible to prevent the downward penetration. . As a result, the floor material 1 can be prevented from being swollen or warped.

  Further, as shown in the figure, the floor material 1 is formed with a concave groove from the upper ends of the butt joint surfaces 26 and 36 so that the resin materials 27 and 37 are internally provided. Intrusion of moisture and the like from the butt joint surfaces 26 and 36 between the materials 27 and 37 can be prevented. In other words, it is desirable to provide the resin materials 27 and 37 so that the top surface of the butt joint surfaces 26 and 36 (the boundary portion with the descending inclined surfaces 26 and 36) does not appear so as to prevent intrusion of moisture or the like. . In addition, the resin materials 27 and 37 may be disposed so as to straddle the butt joint surfaces 26 and 36 and the descending inclined surfaces 25 and 35 so that the side end surfaces thereof appear even below the descending inclined surfaces 25 and 35. Good. If it does in this way, a part of resin material 27 and 37 will be exposed to a design groove | channel, and the design property by the color and texture of the resin material 27 and 37 can also be created.

  In addition, in the case where the particle board is used as the base material 10 as in this example, it is particularly effective when a low-cost particle board having a small resin content, that is, moisture or the like easily penetrates. Therefore, an inexpensive and easily procured particle board can be used as a flooring without any inconvenience. In addition, although the example which comprised the whole base material 10 with the particle board was demonstrated, also when the site | part (surface layer) which included the resin materials 27 and 37 at least is a composite flooring comprised with the particle board, The same effect is produced.

  In addition, if a waterproof coating is formed on the descending inclined surfaces 25 and 35, the effect of preventing intrusion of moisture and the like is further enhanced, but when such treatment is not performed or the coating is peeled off However, it is possible to stop the surface of the resin materials 27 and 37 from infiltrating moisture or the like that has penetrated downward. Therefore, it is possible to minimize the penetration of moisture and the like into the substrate 10.

  Such a flooring 1 is joined on the flooring 1 adjacent to the flooring 3 in the procedure shown in FIGS. In FIG. 2, the floor material 1 installed first among the floor materials 1 and 1 adjacent to each other is expressed as a front floor material 1X, and the floor material 1 installed adjacent to the floor material 1 is expressed as a rear floor material 1Y.

  The procedure shown in FIGS. 2A and 2B is an example in the case of nailing to the male part 20 side. That is, the procedure shown in these drawings is a procedure in the case of joining so that the female real part 30 of the new rear floor material 1Y is fitted to the male real part 20 of the existing front floor material 1X.

  The front floor material 1 </ b> X is fixed to the floor base 3 with an adhesive (not shown) and a nail 5. The nail 5 is driven into the nail driving groove 20a (see FIG. 1) of the male part 30. In addition, it is desirable from the viewpoint of fixing strength that the nail 5 is slanted as shown in the figure.

  In order to install the rear floor material 1Y, after nailing to the front floor material 1X (may be front), the upper surface of the male part 20 of the side end 1a on the male part 30 side of the front floor material 1X is centered. In addition, an adhesive (not shown) is preferably applied to the entire region of the side end portion 1a. The adhesive may be applied to the side end portion 1a of the rear floor material 1Y that is easy to apply. It is desirable to apply an adhesive (not shown) on the floor base 3 on which the rear floor material 1Y is installed.

  Thus, the male part 20 of the rear floor material 1Y is fitted to the female part 30 of the front floor material 1X to which the adhesive (not shown) is applied, and the rear floor material 1Y is placed on the floor base 3. Installed and temporarily fixed.

  Thus, when the side edges 1a and 1a of the flooring materials 1 and 1 are brought into contact with each other, both flooring materials are used when the resin material 27 and 37 are disposed at the same height as in this example. The resin materials 27 and 37 provided in 1 and 1 are also brought into contact with each other and are in close contact with each other. Thereby, not only the entry of moisture and the like from the butt joint surfaces 26 and 36 (Kiguchi), but also the entry of moisture and the like between the butt joint surfaces 26 and 36 can be prevented.

  Next, various flooring materials according to other embodiments of the present invention will be described with reference to FIGS.

  In the flooring 1 shown in FIG. 3A, the thicknesses of the resin materials 27 and 37 are made different from each other in accordance with the thicknesses of the protruding portion 24 and the upper protruding portion 31. Since a thick resin material 37 is disposed on the side end portion 1a on the female real part 30 side in accordance with the thickness of the upper protruding portion 31, it is possible to effectively infiltrate and penetrate moisture from the butt joint surface 36. Can be prevented.

  The flooring 1 shown in FIG. 3 (b) matches the thicknesses of the ridges 24 and the upper protrusions 31 both in the ridges 24 and the upper protrusions 31, and in other embodiments. Resin materials 27 and 37 that are sufficiently thicker than those shown are provided. More specifically, the resin material 27 on the male real part 20 side has a thickness up to the lower end of the inclined lower surface of the protrusion 24, and the resin material 37 on the female real part 30 side is on the lower surface of the upper protrusion 31. The thickness is all the way. Since both ends 1a and 1a are formed with insertion portions 24a and 31a into which the resin materials 27 and 37 are inserted in the back of the base material 10, the resin material 27 can be obtained by using an adhesive (not shown). 37 can be prevented from falling off. Moreover, since the mounting openings for the resin materials 27 and 37 are large, the resin materials 27 and 37 can be mounted smoothly and smoothly in the manufacturing process.

  In the flooring 1 shown in FIG. 3C, sheet-like or thin-plate-like resin materials 27 and 37 are disposed on both the protrusion 24 and the upper protrusion 31. According to this, the resin materials 27 and 37 can be saved, and the cost can be reduced. With this configuration, the substrate 10 can be easily formed by inserting a hard resin plate with an adhesive applied to the plate surface into a previously provided insertion groove. Alternatively, the resin materials 27 and 37 may be formed by pouring a liquid material such as an adhesive into the groove and curing it.

  In the above, the flooring material 1 having a joint structure that can be joined by the male real part 20 and the female real part 30 has been shown. Any floor material may be used as long as the butt joint surfaces 26 and 36 are formed below the lower ends of the descending inclined surfaces 25 and 36 of the side end portions 1a and 1a. For example, it may be a flooring material with a phase stacking structure, a flooring material that can be joined by actuality, or a flooring material that has a flat side end and a flat butt joint surface with no irregularities. Good. Moreover, the floor material whose butt joint surface is not a surface perpendicular | vertical to the surface of a floor material may be sufficient.
