  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a flooring construction method and a floor structure according to the present invention will be described in detail with reference to the drawings. The floor according to this embodiment is applied to a floor such as a double floor of a building such as an independent house, an apartment house, or a public facility.

  The flooring 2 used for the construction of the flooring is a flooring flooring material as shown in FIG. This flooring 2 is a long plate material, with female side portions 4 and 5 (long and narrow projections provided in the upper and lower portions forming a groove in the center) on one side surface of the long side, and male side portions on the other side surface. A real part 6 (a long and narrow protrusion provided in the central part) is formed. Furthermore, female real parts 4 and 5 are formed on one side surface of the short side of the flooring 2, and a male real part 6 is formed on the other side surface. The groove part of the said female real part 4 and 5 can be fitted with the male real part 6 of the other flooring 2, and the said male real part 6 can be fitted with the female real part 4 and 5 of the other flooring 2 It is.

  In the construction of the floor material, as shown in FIG. 2, a particle board is placed on a joist or the like in a predetermined section where a floor is formed by a series of fittings between floor materials 2 such as a building room. A floor base material 14 laid with the above is applied, and the floor material 2 is laid on the upper surface of the floor base material 14 by bonding.

  First, in the step of inking the floor base material 14, the ink is set so that the hot melt adhesive 8 can be arranged in a row at an appropriate interval in a direction orthogonal to the long side direction of the floor material 2. Further, in this marking, the arrangement position of the hot melt adhesive 8 and the floor material 2 are arranged so that the end of the short side of the floor material 2 is always located above the hot melt adhesive 8. Determine the location.

  The hot melt adhesive 8 is a metal foil, a metal plate or a metal net in which an eddy current is induced by a high frequency magnetic flux generated by the electromagnetic induction heater 10 and is joule-heated (as a metal, iron, aluminum, nickel, stainless steel, zinc, A thermoplastic adhesive 13 is applied to both front and back surfaces of a tape-like metal base 12 such as copper and tin. Here, a tape-like hot melt adhesive 8 in which a thermosensitive adhesive 13 is applied to both surfaces of a metal foil made of a ferromagnetic material is used as the metal base 12.

  In the next step, as shown in FIG. 2, the hot melt adhesive 8 is disposed on the upper surface of the floor base material 14 on which the ink marking has been performed. At this time, the hot-melt adhesive 8 is stretched with a pin, and an end portion at the start of bonding and two points at the center are fixed by using a fastener 16 such as a staple. The end of the pasting is opened without being fixed by the fastening device 16 so that the hot melt adhesive 8 is not wrinkled. At the beginning of the application of the hot melt adhesive 8, the hot melt adhesive 8 is disposed in parallel to the long side direction of the flooring 2 and slightly inside the wall 15.

  Then, the floor material 2 is disposed on the hot melt adhesive 8. As shown in FIG. 3, in the first row where the flooring 2 starts to be stretched, after the flooring 2 is arranged, finish nails 18 are driven in the vicinity of both ends of the long-side male part 6 to temporarily fix the flooring 2. When the second-row flooring 2 is arranged, the long-side male solid part 4 of the second-row flooring 2 is fitted into the long-side male solid part 6 of the first-row flooring 2. Let them join.

  In each row, a plurality of flooring materials 2 are arranged in a straight line, and for these flooring materials 2 as well, the male real part 6 and the female real parts 4 and 5 provided on each short side are fitted. And join. These flooring materials 2 are arranged so that the end of the flooring material 2 is positioned on the approximate center of the tape width of the hot melt adhesive 8. The floor materials 2 in the third and subsequent rows are also laid in the same manner, and the floor materials 2 in different rows are arranged in a staggered manner.

  In the process of laying the flooring 2, for example, when the flooring 3 (one or a plurality of sheets) in the 18th row is arranged, as shown in FIGS. 1B and 4, the flooring Among the upper and lower female real parts 4, 5, the floor material 3 in which the lower female real part 5 is notched (notched part 7) is used and arranged. The cutout 7 is formed by cutting out the female side 5 on the long side and the female side 5 on the short side of the flooring. In addition, the floor material 3 in the 18th row is fixed only by heat bonding with the electromagnetic induction heater 10 without driving the finish nail 18.

  When the flooring 3 is peeled off by reforming or the like, the notch 7 of the flooring 3 is not fitted to the male part 6 of the adjacent flooring 2, so that the flooring 3 can be easily peeled off by reheating. Can do. At this time, since both the female side 5 on the long side and the female side 5 on the short side are cut out, not only the flooring adjacent to the long side but also the male of the flooring adjacent to the short side Since the real part 6 is not fitted, the flooring 3 can be easily and independently peeled off. For reinforcement, the hot melt adhesive 8 may be used more than the other floor materials 2 or may be used on the entire surface of the floor material 3.

  With respect to the floor material 3 in the 18th row, a mark indicating that the female real part 5 is cut out is provided at an appropriate location in the floor material 3 itself or in the vicinity thereof. As this mark, here, nails are driven into the surfaces of the walls 15 at both ends in the room of the flooring 3 in the 18th row. The flooring 3 provided with the notches 7 is provided in at least one row in one compartment such as a room. Usually, the number of locations of the flooring 3 is increased according to the size of the section. The area where the floor materials 2 and 3 are peeled off by partial reform or the like is determined by the number of floor materials 3 arranged. For the next floor material 2 after the 19th row, like the floor material 2 up to the 17th row, the female real parts 4, 5 and the male real part 6 are fitted together, and the finish nail 18 is driven and temporarily fixed. To do.

  When the temporary fixing of the flooring 2 is completed, the main fixing is performed by induction heating adhesion using the electromagnetic induction heater 10. The electromagnetic induction heater 10 has a built-in magnetic sensor, and an operator uses this magnetic sensor to confirm the position where the hot melt adhesive 8 is disposed and irradiates directly above the position. In this embodiment, since the metal base made of a ferromagnetic material is used for the hot melt adhesive 8, the magnetic sensor detects this, and the position of the hot melt adhesive 8 can be easily confirmed.

  After the electromagnetic induction heater 10 is irradiated, the builder's body weight is placed on the irradiation portion, and the cooling and fixing are performed. As the floor material in the pasted row, the floor material 3 in which the lower female real part 5 is cut out is used. For the flooring 3, only the induction heating adhesion by the electromagnetic induction heater 10 is fixed without driving the finish nail 18. Thus, the process of laying the flooring 2 is completed.

  Next, a method for removing the flooring 2 when the flooring 2 is replaced by an indoor renovation or the like will be described. First, a case where a part of the flooring 2 is replaced due to partial damage of the flooring 2 will be described. In the work process at this time, first, as shown in FIG. 5, the floor material 3 that is closest to the floor material 2R to be replaced is found by the nail of the mark, and begins to be peeled toward the floor material 2R to be replaced. At this time, since the floor material 3 is formed by cutting out the lower female real part 5 and the finish nail 18 is not driven, the floor material 3 can be easily peeled off by melting the adhesive. .

  As the work, the floor material 3 is re-irradiated with the electromagnetic induction heater 10 while the floor material 3 is attracted by soccer (construction aid with two suction cups) and pulled upward, and solidified, and the heat-sensitive thermoplasticity is solidified. The adhesive 13 is melted and the flooring 3 is peeled off. As for the flooring 2 from the flooring 3 to the previous flooring 2R, the electromagnetic induction heater 10 is re-irradiated while the flooring 2 is being squeezed upward using a tool such as a bar, and the flooring 2 from the end 2 is peeled off. Eventually, the floor material 2 to be replaced is peeled off and the remaining finish nail 18 is removed with a tool. The hot melt adhesive 8 is melted and peeled off by irradiating the electromagnetic induction heater 10 with a backing plate in between or slightly floating.

  When laying a new flooring 2 at a location where the flooring 2 or 2R has been peeled off, first a new hot melt adhesive 8 is placed as described above. A new flooring 2 is arranged on this, the female real part 4 of the new flooring 2 is fitted into the male real part 6 of the existing flooring 2, and a finish nail 18 is driven and temporarily fixed thereto.

  Finally, for the portion corresponding to the floor material 3 that has started to peel off, the floor material 3 in which the lower female real part 5 is cut out is used in the same manner. The floor material 3 is not driven with the finish nail 18. After the temporary fixing, permanent fixing is performed by induction heating adhesion using the electromagnetic induction heater 10, and the flooring process for the flooring 2 is completed. In the indoor remodeling by this construction, only a part of the flooring 2 can be replaced, the work can be easily performed, and the remaining flooring or floor base material 14 is not damaged, and the overall finish is good.

  When the entire floor material 2 in the section is replaced, it can be peeled off from the floor material 3 in the pasted row while being peeled off from the floor material 3 in the 17th row at the same time. These flooring materials 3 can be easily peeled off by melting the adhesive as described above. In this way, the entire work can be quickly performed by peeling the floor materials 2 and 3 from a plurality of locations at the same time. Then, in a state where one row of the flooring 3 is peeled off, the flooring 2 in the subsequent rows is peeled in the same manner as described above. The hot melt adhesive 8 is also peeled off by irradiation with the electromagnetic induction heater 10. The steps for newly laying the flooring 2 are the same as in the case of the entire laying described above, inking, placing the hot melt adhesive 8, temporarily fixing the flooring 2 and 3, and fixing the flooring 2 and 3 permanently. In order.

  Therefore, in the construction method according to the above embodiment, the floor material having the female real part and the male real part is used, and the floor material is bonded and constructed by the hot melt adhesive. The floor material can be attached to the floor, and at least one row of the section where the lower female real part of the floor material is cut is used, so the floor material can be easily peeled off from this part during renovation. it can. As a result, it is possible to easily and quickly repair and refurbish a partial floor material including a damaged floor material in a section (such as a room).

  In the above method, the floor material can be peeled off from a plurality of locations in one section, the peeling work can be performed quickly, and the floor base material can be reused without damaging the floor base material. is there. In general, hot melt adhesives do not contain volatile melting agents such as formaldehyde, so they do not cause sickness such as sick houses, and in addition, floor materials can be removed and laid quietly and repaired with low noise and low vibration. Therefore, it is possible to reduce waste material processing costs by separating and collecting.
