JP 2009-74332 A

  However, when the floor material laid as described above is removed at the time of replacement, the back surface of the adhered floor material must be peeled off from the floor base, and the removal work may take a long time. Moreover, there is a possibility that the floor substrate may be damaged when the floor material is peeled off, and there is a possibility that even the floor substrate needs to be replaced.

  In addition, since the above-mentioned flooring is fixed to the floor base with a fixing member on one side, and the other side end is actually connected to the adjacent flooring, the flooring is made using an electric circular saw. Sometimes it must be dismantled. Therefore, further time is required for the removal work. In addition, there is a risk of damaging the floor floor with an electric circular saw.

  The present invention has been proposed in view of such circumstances, and its purpose is to provide a flooring material that is less likely to damage the floor base during removal and can be removed efficiently, and a method for constructing the flooring material. There is to do.

  In order to achieve the above-mentioned object, the flooring of the present invention has at least one side end portion that protrudes laterally, and the one side end portion and the side end portion of the adjacent flooring material. Are joined together and arranged side by side on the floor substrate, and the ridges are arranged in contact with the floor substrate, and are fixed to the floor substrate by driving a fixing member from the upper surface. The portion including the ridge portion is formed by a driving member bonded to the floor material body.

  In the flooring construction method of the present invention, only the driving member is fixed to the floor base with a fixing member, and the above-mentioned flooring is laid.

  According to the flooring material and the flooring construction method of the present invention, the construction and procedure described above are employed, so that the flooring body can be constructed without adhering to the floor base. The ground is not easily damaged and can be removed efficiently.

  Embodiments according to a flooring material and a flooring construction method of the present invention will be described below with reference to the accompanying drawings. First, the basic configuration of the present flooring 1 will be described.

  The flooring 1 according to the following embodiment, as shown in FIGS. 1, 2, 6, and the like, has at least one protruding end 21 projecting sideward at one side end, This is a flooring that is joined to the side edge of the adjacent flooring 1 and arranged side by side on the floor foundation 30. The protruding portion 21 is arranged so as to be in contact with the floor base 30, and the fixing member 3 is driven from the upper surface so as to be fixed to the floor base 30, and the portion including the protruding portion 21 is a floor material main body. 10 (see FIG. 2 and the like).

  Next, the floor material described in FIGS. 1 to 6 will be described in detail.

  This flooring 1 is a plate material having a substantially rectangular shape (for example, 303 mm × 1818 mm) in plan view. The flooring 1 includes a substrate in which a decorative material is laminated on the surface of a wooden base material as the flooring main body 10. As the wood substrate, various wood materials such as plywood, MDF, and particle board can be used. In addition, in drawing, the flooring main body 10 does not distinguish with a wooden base material and a decorative material, but illustrated them as integral.

  This flooring 1 has a ridge-shaped male part 11 at one side end of each side end part in two directions, and has a grooved female part 12 at the other side end part. Yes. In the construction, the flooring 1 is installed so that the flooring 1 adjacent to the floor base 30 and the side ends are fitted with each other.

  An upper protrusion 13 for forming a groove in the female real part 12 is formed above the female real part 12. Similarly, a protrusion 21 for forming a concave groove is formed below the female real part 12. The protrusion 21 protrudes further to the side than the upper protrusion 13. That is, the part which protruded rather than the upper side protrusion part 13 of the protrusion part 21 can be planarly viewed as shown to Fig.1 (a).

  Thus, at one side end of the flooring 1, the female real part 12 is formed with the upper surface of the ridge part 21 as the lower wall surface of the concave groove, and the female real part 12 can be fitted. The male part 11 is formed at the side end on the opposite side of the one side end.

  The part where the upper part of the protrusion 21 is open is a part where a fixing member 3 such as a screw or a nail is driven from above when the flooring 1 is fixed to the floor base 30. As shown in FIG. 1C, the protrusion 21 is formed of a driving member 20 that is separate from the floor material body 10. The driving member 20 is not limited in material as long as it can be driven with screws or the like, and the same woody material as the flooring main body 10 can be used.

  The driving member 20 is a member in which the entire protrusion 21 is formed, and a part of the driving member 20 is fitted and bonded to a notch 15 having a rectangular cross section formed in a lower corner of the flooring main body 10. Yes. Thus, the driving member 20 includes a protrusion 21 that is screwed and a fitting portion 22 that is fitted to the notch 15.

  The back surface of the driving member 20 and the back surface of the flooring main body 10 are flat and flush. That is, when the flooring 1 is installed on the floor base 30, the back surface of the driving member 20 contacts the top surface of the floor base 30. Since the fixing member 3 is driven directly into the driving member 20 from the upper surface, the driving member 20 is fixed to the floor base 30 without any other members being placed up and down.

  There are at least three methods for attaching the driving member 20 to the notch 15 as shown in FIGS. 6A to 6C, which will be described later.

  The flooring 1 shown in FIG. 1 can be coupled to the flooring 1 adjacently provided in both the width direction and the longitudinal direction by male-female fitting. In order to be combined with such an adjacent flooring material, a male part 11 is provided on two adjacent edges of the four sides, and a female part 12 is provided on the other two edges. . Since the protruding portion 21 is required at the side end portion on the female real portion 12 side, the driving member 20 is attached to the back surface side in an L shape as shown in FIG. Good. The driving member 20 may be an L-shaped member, but may be configured by an individual bar plate-like member for each edge.

  Next, construction (laying) of the floor material 1 on the floor base 30 will be described with reference to FIG. FIGS. 2A to 2C are diagrams illustrating a procedure in which the flooring 1 is sequentially arranged on the floor base 30 along the width direction of the flooring 1.

  The floor foundation 30 is formed by arranging joists 32 on the large pull 31 at a predetermined interval and discarding and attaching a plywood 33 thereon. The flooring 1 is arranged side by side on the upper surface of the discarding laminated plywood 33, and in this example, a construction method is adopted in which the flooring 1 is installed so that the width is matched between the joists 32 and 32. . Further, the installation pitch of the joists 32 matches the width dimension of the flooring 1, and the protrusions 21 formed on the side edges of the longitudinal edges of the flooring 1 are arranged almost directly above the joists 32. Thus, the flooring 1 is installed.

  In this way, the fixing member 3 driven into the ridge 21 is driven and fixed to the joist 32 via the discard pasting member 33. In this example, screws are used as the fixing member 3, but nails and staples may be used.

  As shown in FIG. 2A, the floor material 1 is placed at a predetermined position of the floor base 30, and the protrusion 21 is screwed to the floor base 30. Screwing may be performed at a predetermined interval (for example, 303 mm interval) at the longitudinal edge.

  In this example, the flooring 1 itself is fixed to the floor base 30 only by screwing at the protrusions 21 formed at the adjacent two side ends. That is, the back surface of the flooring 1 is not bonded to the floor base 30. Of course, you may make it the back surface of the flooring 1 adhere | attach the floor base 30 using an adhesive agent or an adhesive.

  Adhesive is applied to the female real part 12 (upper surface of the ridge part 21) of the flooring 1 thus installed and fixed, and the adjacent flooring 1 is applied to the male real part 11 with adhesive. It is installed on the floor base 30 so as to be fitted to the female real part 12 of the existing floor material (see FIGS. 2B and 2C). And the screw | thread stop is made | formed about the adjacent flooring in the protrusion part 21 (refer FIG.2 (c)).

  In this way, the flooring 1 is arranged side by side on the floor base 30 while the male and female joints between the flooring 1 and the screwing to the ridges 21 are repeated in order.

  As described above, for any floor material 1 laid on the floor base material 30 except for the floor material 1 at the end, adjacent two side end portions (edge portions) of the ridges 21 are formed on the floor base material 30. Directly fixed. In addition, the adjacent floor material and the side end portions are joined to each other at all side end portions.

  When the floor material 1 laid in this way is replaced, the floor is obtained by the two methods shown in FIGS. 3 (a) to 3 (c) or FIGS. 4 (a) (b) and 5 (a) (b). The material 1 can be removed (disassembled). 4A and 4B and FIG. 5A and FIG. 5B are a series of one method, and are shown over two figures for convenience of illustration. In any of these removing methods, the floor material body 10 is first removed from the driving member 20 so as to leave the driving member 20 screwed to the floor base 30, and the operation is repeated for all floor materials 1, The driving member 20 remaining on the floor base 30 is sequentially removed.

  As a specific peeling procedure, you may make it peel in order from the flooring 1 of an edge part like FIG. Also, as shown in FIGS. 4 and 5, the intermediate flooring 1 is cut with a tool such as an electric circular saw, and then the adjacent flooring 1 is peeled off and then the adjacent flooring 1 is peeled off. It may be.

  The flooring main body 10 is joined to the adjacent flooring and is bonded to the driving member 20 at one end, but is not directly fixed to the floor base 30, so that the driving member is relatively easy. The floor material body 10 can be removed while only 20 is fixed to the floor base 30.

  After the floor material main body 10 is removed, only the driving member 20 remains on the floor base 30 (see FIGS. 3C and 5B). Since these driving members 20 are screwed, they may be removed sequentially using a screwdriver.

  Thus, if the flooring 1 having the driving member 20 separate from the flooring main body 10 is used, the flooring main body 10 can be constructed without being bonded to the floor base 30. Therefore, if a construction method that does not adhere to the floor base 30 with an adhesive or an adhesive is adopted, when the flooring 1 is replaced, no adhesion marks remain on the floor base 30, and the driving member 20 is also used. Since only the screws are removed, there is almost no possibility that the discarded plywood 33 will be damaged. Therefore, it is not necessary to replace the discarded pasted plywood 33. Further, if screws are used to fix the driving member 20, the flooring 1 can be removed efficiently. Even when nails or staples are used instead of screws, damage to the floor substrate 30 can be minimized by carefully removing the driving member 20.

  Moreover, since it is the construction method which does not use an adhesive agent etc. with respect to the floor base 30, the operation | work which peels the flooring main body 10 can be performed rapidly. In addition, in order to peel off the flooring main body 10 more easily, it is desirable that the flooring main body 10 and the driving member 20 are easily bonded to each other.

  If at least one of the bonding force between the flooring main body 10 and the driving member 20 and the bonding force between the flooring materials 1 is superior to the screwing force of the driving member 20 to the floor base 30, the flooring main body 10 is There is a possibility that the driving member 20 screwed at the time of peeling is also peeled off at the same time. As a result, the floor substrate 30 may be damaged. In order to avoid such a situation, both the adhesive force between the flooring main body 10 and the driving member 20 and the bonding force between the flooring members 1 are made weaker than the fixing force to the floor base 30 by the fixing member 3. It goes without saying that there is a need.

  For example, as shown in FIG. 6, if the sheet 5 is interposed on the adhesive surface between the notch 15 of the flooring main body 10 and the driving member 20, both members can be easily separated. Since the driving member 20 is fixed to the floor base 30 with screws, the driving member 20 can be easily peeled simply by placing the hand on the female real part 12 or the like and lifting it up. As the sheet 5, an olefin sheet or a paper sheet can be used.

  Moreover, although the flooring main body 10 and the driving member 20 can be easily separated by the interposition of the sheet 5, the fitting portion 22 of the driving member 20 is fitted and bonded to the cutout portion 15 to be combined. Therefore, a sense of unity as the flooring 1 is obtained.

  As a method for adhering both members, for example, there are three types of methods shown in FIGS.

  In the example of FIG. 6A, the driving member 20 is bonded to the top surface 15 a and the side surface 15 b of the notch 15 formed in the floor material body 10 via the sheet 5. An adhesive layer may be formed on the front and back sides of the sheet 5. Although it is adhesion via the sheet 5, since the entire bonding surface of both members is adhered, a sense of stability can be obtained.

  Further, as shown in FIGS. 6B and 6C, the driving member 20 is adhered to only one of the top surface 15a and the side surface 15b via the sheet 5, and can be peeled off more easily. It is desirable to do so. In addition, when it adhere | attaches through the sheet | seat 5 of only either the top | upper surface 15a or the side surface 15b, it can peel off from an edge part easily, but it is strong enough with respect to a planar pull etc., and is normal. There is no risk of separation after handling and laying.

  Adhesion between the flooring main body 10 and the driving member 20 is not limited to the above example, and various other methods for easily peeling off can be employed. For example, an adhesive may be scattered and bonded to the top surface 15a and the side surface 15b without using the sheet 5. Further, the side end surfaces may be brought into contact with each other without being provided with the notch 15 and may be bonded.

  Various adhesives such as resin-based, natural rubber-based, and starch-based adhesives can be used as the adhesive for joining both members. Moreover, you may make it adhere | attach both members using a double-sided adhesive tape.

  Next, a flooring 1 according to another embodiment of the present invention will be described with reference to FIG.

  In the flooring 1 shown in FIG. 7, the back surface of the flooring main body 10 is composed of a foamed resin layer 10 b. A driving member 20 is disposed on one side end of the foamed resin layer 10b. If the foamed resin layer 10b and the driving member 20 have the same thickness as in the example of FIG. 7, if they are integrated in advance, they can be manufactured easily. The foamed resin layer 10b may be formed by adhering a foamed resin material made of foamed urethane or the like to the back surface of the substrate 10a on the front side.

  Since the foamed resin material has a lower strength than the wood material, when the flooring 1 is cut with a tool such as an electric circular saw, the foamed resin layer 10b can be easily formed thereafter by cutting only the base material 10b on the surface side. Can be removed. Since there is no need to cut the foamed resin layer 10b in this way, there is almost no risk of damaging the floor substrate 30 with a tool such as an electric circular saw.

  Next, an experiment of disassembling the flooring material 1 for an example in which the various flooring materials 1 described above and two kinds of construction methods are combined will be described. In addition, about the flooring 1, the floor foundation 30, etc. which were used for various experiment, since it is substantially the same as FIGS. 1-7, illustration was abbreviate | omitted. The results of the experiment are shown in FIG.

  First, the flooring 1 (Examples 1-3 and the comparative example 1) is demonstrated. In addition, about the flooring material 1 of an Example and a comparative example, the veneer is used as the surface decorative material, and it has finished the painting. The appearance of the flooring 1 is the same (303 mm × 1818 mm). Moreover, the particle board used for each flooring 1 of Examples 1-3 and the comparative example 1 is the same kind.

Each example and comparative example are as follows.
(1) Example 1
The same kind of particle board is used for the flooring main body 10 and the driving member 20. The driving member 20 is directly bonded to the top surface 15a of the cutout portion 15 of the floor material body 10 with a polyurethane-based adhesive (see FIG. 1 for the configuration and shape of the floor material 1).
(2) Example 2
The same kind of particle board is used for the flooring main body 10 and the driving member 20. The driving member 20 is bonded to the top surface 15a of the cutout portion 15 of the flooring main body 10 with a polyurethane adhesive via a paper sheet (see FIG. 1 for the configuration and shape of the flooring 1). ).
(3) Example 3
The same kind of particle board is used for the base material 10a and the driving member 20 on the front surface side of the floor material body 10, and the foamed resin layer 10b is attached to the back surface side of the base material 10a (configuration of the floor material 1, (Refer to FIG. 7 for the shape). As the foamed resin layer 10b, 20 times foamed urethane foam was used. The driving member 20 is bonded to the top surface 15a of the cutout portion 15 of the flooring main body 10 with a polyurethane adhesive via a paper sheet.
(4) Comparative Example 1
The particle board is used for the flooring (the outer shape of the flooring 1 is the same as in FIG. 1).

Next, the construction method will be described.
(A) Construction method 1
An adhesive is beat-applied on the back surface of the flooring material 1 at a pitch of 303 mm and adhered to the floor base 30, and the ridges 21 are fixed to the floor base 30 with staples. The flooring materials 1 are bonded with an adhesive (see FIG. 2 for an outline of the construction method).
(B) Construction method 2
The back surface of the flooring 1 is not bonded to the floor base 30, and the ridges 21 are fixed to the floor base 30 with screws. The flooring materials 1 are bonded with an adhesive (see FIG. 2 for an outline of the construction method).

  In combination with the above Examples 1 to 3, Comparative Example 1 and Construction Methods 1 and 2, 8 types of construction for 1 tsubo were performed, and after curing for 1 week for each, all flooring materials 1 were electrically It was peeled off from the floor base 30 using a circular saw or bar. After the floor material 1 was removed, the degree of damage to the floor foundation 30 (discarded plywood 33) was confirmed. FIG. 8A is a comparative evaluation table for dismantling time, and FIG. 8B is a comparative evaluation table for the floor foundation 30 after dismantling.

  As shown to Fig.8 (a), about any flooring 1 of Examples 1-3 and the comparative example 1, what was constructed by the construction method 2 was disassembled in a shorter time than what was constructed by the construction method 1. We were able to. Moreover, in the construction method 2, the disassembly time of Examples 1-3 was shorter than the disassembly time of Comparative Example 1. The case where the flooring material 1 of Example 3 was constructed by the construction method 2 could be disassembled at the fastest speed. Even when the flooring material 1 of Example 1 and Example 2 was constructed by the construction method 2, it could be disassembled in a relatively short time. Even in the case of construction according to the construction method 1, the comparative example 1 had to be peeled off by applying a force with a tool such as a bar, and therefore took time.

  As shown in FIG. 8 (b), the floor material 1 after the dismantling of the flooring material 1 of each of Examples 1 to 3 and Comparative Example 1 was lower than that of the construction method 2 was constructed by the construction method 1. The situation of ground 30 was good. When the flooring material of Example 3 was constructed by the construction method 2, the situation of the floor substrate 30 after dismantling was the best. Even when the flooring material 1 of Example 1 and Example 2 was constructed by the construction method 2, it was relatively good, and there was no need to replace the discarded laminated plywood 33. As can be seen from the evaluation table, it was necessary to replace both the working example 1 and the comparative example for the construction method 1. Moreover, about the flooring 1 of the comparative example 1, even if it constructs by the construction method 2, in order to use bar etc., although repairing the floor base 30 was not enough, some repair was required.

  Next, another example of the construction mode of the flooring 1 will be described with reference to FIGS. 9 (a) and 9 (b). The construction mode shown in FIG. 9 is different from that shown in FIG. 2 in that the flooring 1 is laid so as to intersect the joist 32.

  As the flooring 1, one having substantially the same shape as that shown in FIG. 1 or FIG. 7 is used, but the installation pitch of the joists 32 is placed on the driving member 20 (projected portion 21) of the flooring 1. The lower hole 21a is opened according to the above.

  Thus, since the pilot hole 21a suitable for the installation pitch of the joist 32 is provided in the protruding portion 21, if the first screwing is securely performed on the joist 32, the other screwing is also carried out. It can definitely be done for 32.

  The construction method shown in FIG. 9 and the construction method shown in FIG. 2 described above are for discarding screws and fixing the joists 32 to the joists 32 through the laminated plywood 33. However, the fixing method is not limited to this, and the discarded laminated plywood is used. It may be fixed to 33 only, or another fixing method may be used.

  In the various embodiments described above, screws are used to fix the flooring 1 to the floor base 30, but nails and staples may be used. In the case where the nail is used, since the slanting into the concave groove of the female real part 12 is also possible, the protruding part 21 may have a protruding degree similar to that of the upper protruding part 13.

  The embodiment described above is the flooring 1 having a male-female fitting structure as described above. In the case of the floor material 1 having such a male-female fitting structure, if the floor material body 10 as shown in FIG. 1 or the like is formed, it is easy to prepare a long material having a rectangular cross section as the driving member 20. The flooring 1 can be formed on the floor. Further, in the case of the flooring 1 shown in FIG. 7, the foamed resin material and the driving member 20 are attached to the back surface of the mating-shaped flooring. .

  Further, the flooring 1 is not limited to a male / female fitting structure, and may be a flooring structure having a mating structure. In the case of a flooring material having a mating structure, a portion including a practical projecting portion (ridge portion 21) on the lower side of one end portion may be formed by the driving member 20.

  Although the floor material 1 in which the female real part 12 is configured (formed) by attaching the driving member 20 to the floor material main body 10 is shown above, both the male real part and the female real part are included. The floor material main body may be used. For example, a driving member that protrudes outward from the protruding portion below the female real part is bonded to the back surface of such a flooring main body, and the foamed resin is bonded to the male real part side to which the driving member is not bonded. What is necessary is just to comprise a flooring by providing a layer. In this case, it is assumed that the fixing member such as a screw is not driven into the protruding portion below the female real part, but is driven into the portion protruding from the female real part of the driving member (the ridge).
