Description

  The present invention relates to an interior building material, and more particularly to an interior building material suitable as a plate material that forms a floor or a wall in a building, for example, a flooring material or a wall plate material.

  A floor mainly made of wood material is generally called flooring. Plate materials used for flooring are roughly classified into single-layer flooring materials and composite flooring materials. The single-layer flooring material is generally made of a solid material, and the composite flooring material is made by bonding and laminating a decorative single plate on the surface with a plywood or the like as a core material. Many of such flooring materials have a strip shape. Patent Document 1 discloses an example of a single-layer flooring material. As shown in Patent Document 1, sane is formed on one side in the longitudinal direction of the strip-like flooring material, and a groove is formed on the other side. In the conventional flooring construction, there are a method in which a flooring material is laid on a joist and pasted (a joist straight), or a method in which a flooring material is laid on a base plate installed on the joist. When flooring a floor of a building, usually flooring materials that are adjacent to each other are inserted into the grooves formed on each side, and in that case, the joists and nails are stripped with joists And so on.

The sinks and grooves on both side surfaces of the flooring material are mainly provided to prevent the flooring material from warping due to moisture and the like to lift from the base support part (the joist or base plate). Specifically, the flooring materials adjacent to the side surface side are connected to each other by fitting of the sash and the groove portion, and each flooring material is fixed to the base support portion by concealing nails, thereby providing a flooring material. The warp is not generated. In addition, when performing flooring finishing, a cushion material etc. may be arrange | positioned at a base | substrate support part as needed.
Japanese Patent Laid-Open No. 08-151895

  However, in the conventional flooring material, as described above, the flooring materials adjacent to each other on the side surface side are connected by the sun and the groove portion so as not to generate warpage, and are further fixed to the base support portion by hidden nailing. Therefore, any flooring material that has been damaged after the flooring finish is replaced partially, or any flooring material is temporarily supported by the base when wiring is performed between the flooring material and the base support section. It was not possible to remove from the floor, and it was necessary to remove all of the flooring material arranged on the base support section or to remove it from the corner of the floor surface to a predetermined location.

  The object of the present invention is to solve such a conventional problem. For example, when used as a flooring material or a wall plate material, an arbitrary plate material can be easily removed and replaced after the flooring or wall finishing, or An object of the present invention is to provide an interior building material that can be re-installed and that does not warp the plate material.

  The present invention is an interior building material in which a wooden decorative veneer is attached to one surface of a core material, and the feature of the interior material is that the core material is compressed and solidified by mixing paste with wood powder. It is either a plate-like MDF base material or plywood, and a rubber mat, an asphalt type, or a vinyl chloride type buffer mat is stuck to the other surface of the core material, and the surface shape of the interior building material is The interior building material is formed in a flat surface substantially perpendicular to the surface, and when the plurality of interior building materials are arranged on the installation surface, the adjacent interior building material is flat. The peripheral surfaces are in contact with each other and are detachably disposed on the installation surface.

  In another example of the embodiment of the interior building material according to the present invention, a non-woven fabric is attached to the surface opposite to the surface of the buffer mat bonded to the other surface of the core material.

  In another example of the embodiment of the interior building material of the present invention, the core material has a thickness of 2.5 to 5 mm, the decorative veneer has a thickness of 0.3 to 1.0 mm, The buffer mat has a thickness of 2 to 5 mm.

  According to the interior building material of the present invention, since any one of a plate-like MDF base material and plywood formed by mixing paste into wood powder and compressing and solidifying is used as the core material, the occurrence of warping and shrinkage is extremely small. Therefore, when this interior building material is used, for example, as a flooring material, it is not necessary to provide a sash on the side surface and connect to the adjacent flooring material as in the case of a conventional flooring material. be able to. As a result, any flooring material on the flooring floor can be easily removed, so communication wiring for computers, telephones, etc. can be easily laid on or removed from the underlying floor where the flooring material is placed. I can do it.

  In addition, according to the interior building material of the present invention, since the nonwoven fabric is adhered to the surface (lower surface) opposite to the surface of the cushion mat that is adhered to the core material, the interior building material is adhered to the base portion with an adhesive. After removing any interior building material from the base surface, the nonwoven fabric is peeled off from the lower surface of the cushion mat, so that the interior building material can be easily removed. In addition, in the interior building material of the present invention, the thickness of the core material is 2.5 to 5 mm, the thickness of the decorative veneer is 0.3 to 1.0 mm, and the thickness of the buffer mat is 2.0 to obtain the above-described effects. It is preferable to set it to -5.0 mm. Further, as the buffer mat, a rubber-based buffer mat, an asphalt-based buffer mat, or a buffer mat formed of vinyl chloride can be used.

  Hereinafter, preferred embodiments of the interior building material of the present invention shown in the drawings will be described in more detail. 1 and 2 show an interior building material according to a first embodiment of the present invention. The interior building material of this embodiment is an example of the flooring material 10 that is laid on the base floor surface 30 (see FIG. 4) in the building and is subjected to a flooring finish. Therefore, the interior building material of the present invention will be described as the flooring material 10 in this embodiment. As shown in FIG. 1, the flooring material 10 has a plate-like shape having a length (L) of about 1000 mm, a width (W) of about 100 mm, a thickness (S) of about 6.5 mm, and a planar shape of a rectangle. An MDF base material is used as the core material 11. Such dimensions and planar shape of the flooring material 10 are merely examples, and can be changed as necessary. The MDF base material is obtained by compressing and solidifying wood powder with paste. The core material 11 made of this MDF base material preferably has a thickness of 2.5 to 5.0 mm, more preferably 2.5 mm.

  A decorative veneer 12 having the same size as the upper surface 11a is attached to one surface 11a, which is the upper surface of the core material 11 made of an MDF base material, with an adhesive. The decorative veneer 12 is obtained by processing (slicing) natural wood such as a tree, a birch tree, or a cherry tree into a plate shape. The decorative veneer 12 preferably has a thickness of 0.3 to 1.0 mm, more preferably 0.5 mm. Four side edge portions on the surface side of the decorative veneer 12 are chamfered, and a resin coating 13 made of urethane or the like is formed on the surface of the decorative veneer 12. This coating film 13 is for giving gloss to the surface of the decorative veneer 12 and for protecting the surface to prevent scratches.

  A rubber buffer mat 14 is adhered to the lower surface of the core material 11 made of an MDF base material, that is, the other surface 11b opposite to the one surface 11a to which the decorative veneer 12 is bonded, with an adhesive. The rubber-based buffer mat 14 preferably has a thickness of about 2.0 to 5.0 mm, more preferably 3.0 mm. The rubber cushion mat 14 is a compression-molded rubber material and can be used as an anti-vibration mat. The rubber-based buffer mat 14 has a cushioning function against vibration because it has a high cushioning property, that is, an anti-vibration property. Therefore, the vibration generated on the flooring floor on which the flooring material 10 is arranged is difficult to be transmitted to the base floor surface 30, and a high soundproofing and vibrationproofing effect can be obtained. In addition to the rubber buffer mat 14, an asphalt buffer mat can be used. The asphalt buffer mat is compression-molded by mixing asphalt with an inorganic substance, for example, metal powder such as glass powder or iron powder, or other inorganic material powder. This asphalt buffer mat is also the same as the rubber buffer mat 14. Therefore, the vibration generated on the flooring floor can be hardly transmitted to the base floor 30. Further, a thin plate made of a vinyl chloride resin can also be used as a buffer mat because of its cushioning property, that is, vibration proofing.

  A nonwoven fabric 15 is bonded to the lower surface of the rubber cushion mat 14 with an adhesive. The nonwoven fabric 15 is intended to be easily peeled off when the flooring material 10 is removed from the base floor surface 30 after the flooring material 10 is attached to the base floor surface 30 with an adhesive or the like to finish the flooring. That is, when the flooring material 10 is attached to the base floor surface 30 with an adhesive and then is forcibly lifted from the base floor surface 30 in order to peel it off the base floor surface 30, the non-woven fabric 15 is torn and the flooring material 10 10 can be easily peeled off from the ground floor 30.

  As a method for forming such a flooring material 10, for example, when forming the flooring material 10 having a length (L) of 1000 mm and a width (W) of 100 mm, the length is 2150 mm, the width is 110 mm, and the thickness is 2 A core material 11 made of a .5 mm MDF base material is prepared, and a decorative veneer 12 having the same size as the surface 11a is layered on one surface 11a of the core material 11 and attached with an adhesive. Thereafter, a plate member (semi-finished product) having a length of 2150 mm is cut in half to obtain two plate members having a length of 1075 mm. A rubber buffer mat 14 having a thickness of 3 mm and having the same size as the lower surface is attached to the lower surface of each plate member with an adhesive. Next, the plate member is cut to have a length of 1000 mm and a width of 100 mm, and the four side edges of the decorative veneer 12 are chamfered, and then the surface of the decorative veneer 12 is coated with a resin material. Then, the protective coating film 13 is formed, and finally, the nonwoven fabric 15 is pasted on the lower surface of the rubber cushion mat 14 to complete.

  In the case of flooring the floor of the building with the flooring material 10 formed in this way, an adhesive is applied onto the scraper plate 30 which is the base floor surface installed on the joists 31 as shown in FIG. While being applied, the flooring material 10 is stretched as shown in FIG. At this time, in this flooring material 10, each side surface 10 a and end surface 10 b are flat surfaces substantially perpendicular to the surface on which the coating film 13 is formed, so that the adjacent flooring materials 10 are adjacent to each other as shown in FIG. 4. Are aligned and affixed to the base plate 30. Since this flooring material 10 is affixed to the base discard board 30 with an adhesive via a nonwoven fabric 15 attached to the lower surface of the rubber cushion mat 14, it is necessary to install the base discard board 30 as a base support part. . However, in the flooring material 10 according to the first embodiment, when flooring the floor of a building, the foundation is not limited to the ground discard board 30, but the foundation floor (slab) finished with concrete or mortar. ) Etc.

  FIG. 5 shows a second embodiment of the interior building material of the present invention. The second embodiment is also an example of a flooring material 20 for flooring a floor in a building. This flooring material 20 is different from the flooring material 10 of the first embodiment in that a natural wood veneer 21 is disposed between a core material 11 made of an MDF base material and a rubber cushion mat 14. Since the rest of the configuration is the same, the same reference numerals are given to the same or corresponding parts as those of the flooring material 10 according to the first embodiment in FIG. 5, and detailed description thereof is omitted.

  In this flooring material 20, a natural wood veneer 21 having the same size as the other surface 11 b is formed on the other surface 11 b opposite to the one surface 11 a of the MDF base material 11 as the core 11. Is attached with an adhesive. The veneer 21 also has substantially the same thickness as the veneer 12 and has substantially the same water absorption rate as the veneer 12. In order for the decorative veneer 12 and the veneer 21 to have substantially the same moisture absorption rate, the decorative veneer 12 and the second veneer 21 are preferably formed from the same lumber. That is, for example, when the decorative veneer 12 is made of wood, it is preferable that the veneer 21 is also formed from the same lumber. Thus, if the decorative veneer 12 and the veneer 21 are formed (acquired) from the same lumber, both have the same moisture absorption rate. Thus, by disposing the veneer 21 having the same moisture absorption rate as the decorative veneer 12 between the core material 11 and the rubber cushion mat 14, the internal which causes the warp acting on the two veneers 12, 21 is caused. Since the direction of the stress is canceled out, the slight bending stress that may be generated in the core material 11 by the decorative veneer 12 is suppressed, and the side is provided so that any interior building material can be easily removed. Even if not, the flatness of the flooring can be maintained over a long period of time. In addition, in the flooring materials 10 and 20 which concern on each embodiment mentioned above, although it was a thing about the example which used the MDF base material as the core material 11, in this invention, a plywood is used as a core material besides a MDF base material. You can also

  By the way, the floor surface in the flooring finished building is loaded in various manners, and particularly as a loading manner in which it is difficult to maintain the flatness of the flooring, for example, 1 by a table or a leg of a chair. It is a concentrated load exerted on a part of one flooring material. When such a partial load is exerted on one flooring material, both ends in the longitudinal direction of the flooring material are lifted from the base plate 30 or the base floor surface (slab) with the load applied to the flooring material as a fulcrum. The bending force that bends to act will act. When receiving such a load, the flooring material such as the present invention which is not connected to the flooring material adjacent to the sane and the groove as in the prior art, the ground scraper 30 or the ground floor surface (slab slab) at both ends of the flooring material. ) Is a concern.

  Therefore, a flooring material 40 that can reliably maintain the flatness of the flooring even when a concentrated load is partially applied to the surface of one flooring material is shown in FIG. 6 as a third embodiment. This third embodiment also exemplifies the case of flooring the floor in the building. In FIG. 6, the same reference numerals are given to the same or corresponding parts as the flooring material 10 according to the first embodiment, and the detailed description thereof is omitted. This flooring material 40 has a decorative veneer 12 attached to one surface 11a of a core material 11 made of an MDF base material, a rubber or asphalt buffer mat 14 attached to the other surface 11b, and the surface of the buffer mat 14 Although it is the same as the flooring material 10 of 1st Embodiment in the point which is formed by affixing the nonwoven fabric 15 to the plurality of cut portions 41 reaching the core material 11 made of the MDF base material from the surface of the nonwoven fabric, the flooring It differs in that it is formed with a predetermined interval in the length direction of the material 40. These cut portions 41 extend in the width (W) direction of the flooring material 41 and are formed so as to completely traverse the flooring material 41.

  As described above, the flooring material 40 is also laid down while applying an adhesive on the discard board 30 which is the base floor surface, or while applying an adhesive to the base floor surface (slab) finished with concrete or mortar. Flooring is done by laying down. According to such a flooring material 40, even when a large load due to a table or a chair leg is concentrated on a part of the flooring material 40, the bending generated in the flooring material is absorbed by the cut portion 41. Therefore, it does not reach both ends which are free ends, and as a result, it is possible to prevent lifting of both ends from the ground discard plate 30 or the ground floor (slab). In addition, also about the flooring material 40 which concerns on this embodiment, it can replace with a MDF base material and can use the core material 11 which consists of a plywood.

  In each of the above-described embodiments, the flooring material has been described as an example. However, the interior building material of the present invention is not limited to the flooring material, and is also suitable as a plate material that forms a wall of a building, that is, a wall plate material. Can be used. In the above-described embodiment, the decorative veneer 12 or veneer 21 is bonded to the core 11 made of an MDF base material or plywood with an adhesive, and the rubber-based buffer sheet 14 is bonded to the core 11 or veneer 21. The adhesive used here is the trade name "GA spray" marketed as an auxiliary adhesive for tile carpets, or the product marketed as peel-up adhesives for tile carpets. The name “Eco GA Cement” is used. However, in the interior building material of the present invention, it is not limited to the adhesive to be used, and there is no environmental problem, and any adhesive can be used as long as it is suitable for joining the materials described above. Also good.

  Moreover, in the interior building material of each embodiment mentioned above, although the length (L) is 1000 mm and the width (W) is 100 mm as an example, the present invention is not limited to this size. It can be set as an interior building material having a size suitable as a material or a wall board material. For example, as the flooring material, in addition to the examples described in the above embodiments, a square shape having a length (L) of 500 mm and a width (W) of 500 mm, a length (L) of 910 mm, and a width Since a rectangular shape having (W) of 75 mm is used, it is needless to say that the interior building material of the present invention can be applied to such a size.

  As described above, according to the interior building material of the present invention, since either a plate-like MDF base material or plywood obtained by mixing paste with wood powder and compressing and solidifying is used as a core material, warping and For example, when this interior building material is used for a flooring material, it is not necessary to provide a sash on the side surface and connect to an adjacent flooring material as in the case of a conventional flooring material. You can line up each other. As a result, any flooring material on the flooring floor can be easily removed, so communication wiring such as computers and telephones or various cables can be easily laid on the base floor where the flooring material is placed. Or can be removed.
