Description

  The present invention relates to a unit flooring, and more particularly to a unit flooring in which a plurality of flooring materials are integrally formed.

  In recent years, wooden flooring has gained popularity for reasons such as cleanliness and design. As one of the main construction methods for flooring, so-called parquet construction using a plurality of flooring panels is known. Parquet construction is a construction method in which a large number of flooring panels that are unified in a certain size are laid at a predetermined position.

  In such parquet construction, a flooring panel in which a male solid part of a ridge is provided on one longitudinal side surface and a groove-shaped female real part is provided on the other longitudinal side surface is known. (For example, Patent Document 1).

When laying a flooring panel of such a shape on a floor foundation such as concrete, for example, the following construction method is taken. First, an adhesive is applied to the back surface of the flooring panel. And it affixes on a floor base | substrate directly, fitting a male real part to a female real part. When the flooring panel is laid on the joist, the male part is fitted to the female part as in the above, and the nail is struck on the joist in that state. In this case, it is not necessary to use the adhesive.

  However, parquet construction using the above-described flooring panel has the following problems.

  Laying the flooring panels one by one on site was labor intensive and costly compared to normal flooring construction. Moreover, since construction time is also required, when the construction period is short, the parquet construction may not be employed.

  In addition, in order to arrange in parallel so that there is no gap between the adjacent flooring panels at the construction site, advanced technology is required, and construction could not be performed easily unless a skilled worker.

  Furthermore, since each flooring panel is independent one by one, for example, if there is unevenness in the floor ground such as a concrete floor, only the flooring panel on that unevenness may rise or sink. It was. The fact that only such a single flooring panel floats or sinks discontinuously has a problem that the unevenness of the finished surface becomes conspicuous.

  The present invention proposes to solve the above-described conventional problems, and provides a unit flooring that can be easily and quickly applied even by a non-skilled worker and that the finished surface is less likely to be uneven. The purpose is to do.

  The first unit flooring of the present invention is based on the premise that a plurality of flooring materials are integrally formed in a predetermined shape, and is adjacent to the flexible sheet and the upper surface of the flexible sheet in the width direction. And a plurality of flooring materials stuck together.

  According to this configuration, a plurality of integrally formed flooring materials can be laid as a single unit flooring, which greatly reduces labor and time compared to laying floor materials one by one. As a result, construction costs can be reduced.

  Further, the plurality of flooring materials are connected by the sheet without forming a gap between the adjacent flooring materials. This eliminates the need for advanced technology to avoid providing gaps between flooring materials when laying flooring materials on-site, and construction can be done easily even without skilled workers. .

  Furthermore, since the sheet has flexibility, the unit flooring can be bent. For this reason, even when there is a concave or convex unevenness in the floor base, only one flooring will not be discontinuously floated, and it will become familiar to the unity as a whole unit flooring, Unevenness on the surface of the unit flooring can be made inconspicuous.

  Moreover, it is desirable that the side surface of each flooring material is provided with a taper toward the inner side of the lower surface. As described above, even when there is a convex unevenness on the floor base, this taper allows the unit floor material surface to be slightly bent into a convex shape. As a result, the unit floor material as a whole becomes easy to adapt to the unevenness of the floor base, and the unevenness on the surface of the unit floor material can be made inconspicuous.

  Furthermore, it is desirable that a chamfered portion with chamfered corners is formed on the surface side of the flooring material of the present invention. When there is a concave unevenness in the floor base as described above, the surface of the unit flooring can be bent concavely by this chamfered portion. As a result, the unit flooring is easily adapted to the unevenness of the floor base, and the unevenness on the surface of the unit flooring can be made inconspicuous.

  The second unit flooring of the present invention is based on the premise that a plurality of flooring materials are integrally formed in a predetermined shape, and a plurality of flooring materials arranged adjacent to each other in the width direction, and the plurality of flooring materials And a flexible sheet that is detachably attached to the upper surface of the sheet.

  According to this configuration, a plurality of integrally formed flooring materials can be laid as a single unit flooring, which greatly reduces labor and time compared to laying floor materials one by one. As a result, construction costs can be reduced.

  As an important point of the second invention, the sheet is adhered to the upper surface of the flooring. Thereby, it can prevent that the upper surface of a flooring is damaged at the time of construction or transportation, and can protect the surface. Since the sheet material can be peeled, the sheet material can be peeled off from the floor material after the unit floor material is laid on the floor base or the like. Therefore, it is possible to provide a substantially new flooring panel by sticking the sheet until after the construction, and removing it immediately before the occupant moves in, for example.

  By adopting the configuration as described above, in the present invention, it is possible to easily and quickly perform the construction, and it is possible to make it difficult to make irregularities on the finished surface.

  Hereinafter, the unit flooring according to the first embodiment of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention. Drawing 1 is a figure showing the back of the unit flooring in a 1st embodiment. FIG. 2 is a cross-sectional view of the unit flooring in the first embodiment. FIG. 3 is a cross-sectional view of adjacent floor materials when the unit floor material is bent in the first embodiment. FIG. 4 is a cross-sectional view when the unit flooring in the first embodiment is bent.

  In the unit flooring 1, floor materials 2 having a predetermined width and a predetermined length are arranged adjacent to each other in a plurality of width directions. Further, the plurality of adjacent flooring materials 2 are arranged in a state of being slightly shifted in the vertical direction so as to coincide with a so-called herringbone pattern to be described later. The plurality of flooring materials 2 are integrally configured by sticking a flexible sheet material 3 such as a nonwoven fabric on the back surface.

  Each flooring 2 is provided with a taper 2c whose longitudinal side surface is directed toward the inside of the lower surface. For this reason, the space | interval of the flooring 2 is comprised so that it may become large as it approaches a lower surface. Further, chamfered portions 2 b are formed at the corners in the upper surface longitudinal direction of each flooring 2.

  About the material of the flooring 2, although it consists of a mug material which used the cover as the base material, it is not necessarily limited. For example, various base materials such as other broad-leaved trees such as beech and so on, southern materials such as apton, mug materials such as conifers, and plywood can also be used.

  A plurality of such flooring materials 2 are arranged adjacent to each other in parallel, but as described above, the end portions are sequentially shifted in a lame manner to form a stepped step portion 2a. In the unit flooring 1 of the present embodiment, two types of unit flooring 1a and 1b that are mirror-symmetrical are used.

  The sheet material 3 only needs to have a function of connecting the plurality of flooring materials 2 to each other by sticking, and the shape thereof is not limited. Therefore, as long as the sheet material 3 can reliably connect the plurality of flooring materials 2, it is not necessary to stick the entire back surface. In this embodiment, it is comprised by the elongate strip shape ranging over the flooring 2 width direction for the reason of cost. The thickness of the sheet material 3 is not particularly limited as long as it has the strength to hold the floor material 2 together. However, the thinner one is preferable not only from the viewpoint of reduction of material cost and flexibility, but also from the viewpoint that the laid unit flooring is stable without wobbling. That is, as will be described later, when the unit flooring 1 is laid on the floor base, a level difference is generated between the sticking portion and the non-sticking portion of the sheet material 3 by the thickness of the sheet material 3. As a result of the difference in level, the unit flooring 1 may become unstable and become unstable. For this reason, the thickness of the sheet material 3 is made thin in order to make the step as small as possible.

  Moreover, in this embodiment, the nonwoven fabric is used from the surface of a softness | flexibility and the cost as the sheet | seat material 3 which connects the several flooring 2. However, there is no particular limitation as long as it has flexibility, and for example, a paper material, a synthetic resin, a rubber material, or the like may be used.

  With the above configuration, even when the floor base is uneven, the unit flooring 1 can bend following the unevenness of the floor base, and the surface unevenness can be made inconspicuous.

  For example, when there is a convex unevenness on the floor base, the unit flooring can bend in a convex shape following the unevenness by providing a taper 2c on the side surface of each flooring 2. (FIG. 3A). On the other hand, when there is a concave unevenness in the floor base, the unit flooring can bend into a concave shape following the unevenness by forming the chamfered portion 2b at the corner of the upper surface of the flooring 2. Yes (Fig. 3B). This is because the chamfered portion 2b prevents the corner portions of the adjacent flooring 2 from interfering with each other when bent into a concave shape.

  Moreover, the point that the sheet material 3 is flexible also enables the unit floor material 1 to bend in the width direction of the floor material 2. Since the sheet material 3 bends following the unevenness of the floor base, only the floor material on the uneven surface is prevented from floating or sinking. That is, as shown in FIG. 4, even if one floor material is lifted, the adjacent floor material 2 is connected to the raised floor material 2, so that the unit floor material 1 as a whole absorbs unevenness. Can be made inconspicuous.

  In the unit flooring 1, for example, the sheet material 3 having an adhesive applied to the surface thereof is disposed on the bottom of a frame that matches the outer shape of the unit flooring 1. And it forms so that each flooring 2 may be inserted in a frame and pressed down from the sheet material. According to this method, since it is only necessary to sequentially arrange and bond the flooring 3 to the frame that matches the shape of the unit flooring 1, it can be manufactured easily and quickly, and the manufacturing cost can be reduced.

  Next, a flooring construction method using the unit flooring 1 will be described. FIG. 5 is a diagram illustrating an arrangement example of unit floor materials in the first embodiment. First, remove the sand, dust, etc. on the floor base surface and clean it cleanly. This is because if there is sand or dust on the surface, the adhesive strength of the adhesive described later cannot be exhibited. Next, the unit flooring 1 is provisionally arranged on the floor base, and the arrangement is determined while confirming the overall balance, for example, whether the aesthetics are impaired by the continuity or discontinuity of the grain.

  In the present embodiment, as shown in FIG. 5, two unit floor materials 1a and 1b that are mirror-symmetric are faced to each other so that the stepped portions 2a face each other, and are arranged so that the stepped portions 2a are fitted to each other. By repeating such an arrangement throughout the room, a herringbone-like flooring is formed. In the present embodiment, the herringbone pattern is designed. However, as will be described later, various designs are possible by changing the arrangement of the unit flooring 1. Moreover, you may change the shape of unit flooring 1 itself.

  If arrangement | positioning is decided, the unit flooring 1 which apply | coated the urethane resin adhesive on the back surface will be mounted on a floor base, and the unit flooring 1 will be affixed on a floor base, applying a load slowly. As the adhesive, it is possible to use an epoxy resin adhesive or an emulsion adhesive, but when these adhesives are cured, they are easily damaged when subjected to a load due to movement of a person, for example. have. On the other hand, the urethane resin adhesive has a certain elasticity even at the time of curing, and has an advantage that it is not easily damaged even under a load.

  Here, since the sheet material 3 is thin, only a few steps are provided between the portion where the sheet material 3 is adhered and the portion where the sheet material 3 is not adhered. For this reason, when the unit flooring 1 is placed on the floor base, a gap is not formed between the unit flooring 1 and the floor base, and the state where the floor base is kept in contact with the floor base is maintained. be able to. This not only prevents the unit flooring 1 from becoming unstable due to the level difference, but also has an effect of strengthening the adhesive force of the adhesive applied between the unit flooring and the floor base. .

  Moreover, since the sheet | seat material 3 consists of nonwoven fabrics, it has the structure which can be easily cut | disconnected with a cutter knife etc. For this reason, the number of flooring materials 2 can be easily reduced by cutting the sheet material 3. Thereby, even if there is a case where it is desired to reduce the number of flooring materials 2 for only some unit flooring materials 1 for reasons such as the size and shape of the room, it is possible to quickly respond to the site by cutting the nonwoven fabric 3. I can do it.

  In this way, the flooring is applied to the entire room by sequentially bonding the unit flooring 1 to the floor base.

  As described above, the unit flooring 1 composed of a plurality of flooring 2 is regarded as one unit, and this is sequentially laid on the floor base, so that it takes much more time than when laying one by one as in the past. And can save time and effort.

  Moreover, the unit flooring 1 is already arranged and formed in the construction site so that there is no gap between the adjacent flooring 2. For this reason, it is not necessary to perform one of the most difficult operations of arranging the flooring 2 side by side so as not to provide a gap at the construction site, and the construction can be easily performed even if it is not a skilled worker.

  Further, in the conventional construction method, since each floor material is independent, it is necessary to firmly fix the floor material to the floor base material by nailing after bonding. On the other hand, since the unit flooring 1 of the present embodiment is configured by integrating a plurality of flooring materials 2, it is not necessary to fix them by nailing one by one, saving labor and time. I can do it.

Next, the case where the unit flooring of this embodiment is arrange | positioned with the arrangement | positioning method different from the above is demonstrated. Drawing 6 is a figure showing another example of arrangement of a unit flooring in a 1st embodiment.
In this arrangement example, unlike the above, two types of unit floor materials 1a and 1b that are mirror-symmetrical are not required, and only one type of unit floor material 1 is used. The configuration itself of the unit flooring 1 is the same as that of the unit flooring described above. A flooring pattern aligned in one direction can be formed simply by arranging one kind of unit flooring 1a or 1b (1a in FIG. 6) in the longitudinal direction.

  Next, the modification of the unit flooring of this embodiment is demonstrated. FIG. 7 is a diagram illustrating an arrangement example of a modified example of the unit floor material in the first embodiment. As described above, the unit flooring 11 does not include the plurality of flooring 12 provided with the stepped portions 2a in a lame manner, but is configured to be rectangular with both ends aligned. When this unit flooring is arranged, a flooring pattern aligned in one direction can be formed simply by sequentially juxtaposing them in the same direction. Since this unit flooring is not provided with a stepped portion, it is not necessary to fit the stepped portion at the time of arrangement as in the first embodiment, and can be laid more easily.

  In addition, embodiment mentioned above is an example which actualized this invention, Comprising: The thing of the character which limits the technical scope of this invention is not.

  Next, a second embodiment of the present invention will be described. FIG. 8 is a cross-sectional view of a unit floor material in the second embodiment. The present embodiment will be described with a focus on differences from the first embodiment, and description of common points will be omitted.

  The unit floor material 81 includes a plurality of floor materials 82 and a sheet material 83. Since the flooring 82 has the same configuration as the flooring of the first embodiment, description thereof is omitted.

  The sheet material 83 of the present embodiment is attached to the upper surfaces of the plurality of floor materials 82. The sheet material 82 only needs to have flexibility and adhesiveness. For example, a synthetic resin such as polyethylene, polypropylene, and polyvinyl chloride can be used. In the present embodiment, it is made of a polyethylene film because it does not generate harmful gas even when burned after use, and is excellent in waterproofness. The back surface of the sheet material 83 has adhesiveness. The adhesive force of the sheet material 83 has an adhesive force that can reliably connect a plurality of flooring materials, while being peelable after sticking as shown in FIG. 8B.

  The sheet material 83 is adhered to the entire upper surface of the floor material. For this reason, it also has a function as a curing sheet for preventing dust and dirt from adhering to the upper surface of the flooring 82 during construction and transportation, or preventing scratches and the like. That is, a flooring used in a house or the like is constructed at a construction site, and then construction of walls and ceilings is performed. For this reason, after the flooring construction is completed, a curing operation such as laying a normal curing sheet is performed so that the surface of the flooring 82 is not damaged. Since the sheet material 83 of the present embodiment is adhered to the floor material 82 in advance, it is not necessary to spread a curing sheet at the construction site, and labor and time can be greatly saved.

  Next, the construction method of the unit flooring 81 according to the present embodiment will be described.

  First, the unit flooring 81 having a back surface coated with a urethane resin adhesive is placed on the floor base. Then, the unit flooring 81 is adhered to the floor base while slowly applying a load. In the present embodiment, unlike the first embodiment, the sheet material 83 is adhered to the upper surface. For this reason, on the back surface side of the unit flooring 81, no step is generated between the sticking portion and the non-sticking portion of the sheet material 83, and the unit flooring 81 is stably laid.

  Even if the floor base is uneven, since the sheet material 83 has flexibility, the unit floor 81 is bent according to the unevenness of the floor base.

  Then, it takes a while until the adhesive is cured. Usually, since the unit flooring 81 is sequentially spread, the adhesive is cured during that time.

  When it is confirmed that the adhesive is completely cured, the sheet material 83 is peeled from the floor material 82 as shown in FIG. 8B. Since the sheet material 83 is adhered to the entire surface of the floor material 82, the surface of the floor material 82 is protected and protected. Therefore, the unit flooring 81 in a new state can be provided without dust or dirt adhering to the surface of the unit flooring 81 after being peeled off or causing scratches.

  The sheet material 83 is preferably peeled off after the installation of the ceiling and wall surfaces is completed, not immediately after the unit floor material 81 is laid. Thereby, it has a function as a curing sheet for preventing the surface of the unit flooring 81 from being soiled or scratched during the construction of the ceiling and the wall surface.

  Alternatively, the sheet material 83 may not be peeled off at the time of construction, but may be peeled off when the resident moves in. At this time, since the sheet material 83 can be easily peeled off, the resident himself may peel off.

  As described above, the unit floor material composed of a plurality of floor materials only needs to be laid out one by one as a unit. For this reason, labor and time can be greatly shortened compared with laying floor materials one by one.

  In addition, since a plurality of adjacent floor materials are arranged in advance at an appropriate interval, it is not necessary to perform a difficult operation of arranging the floor materials one by one on the site.

  The unit flooring according to the present invention can be applied easily and quickly, and the finished surface is difficult to be uneven, and is useful in flooring construction such as design construction and mosaic parquet construction.
