Can be done. Further, the entire height of the parting material 3 can be adjusted by the pitch of the small protrusions 8 and 9 by changing the pushing amount of the connecting vertical side portion 6 b into the groove 7.

  Hereinafter, the tatami laying method of Embodiment 1 will be described with reference to FIGS. In FIG. 5 and subsequent figures, the illustration of the floor base 4 is omitted.

As shown in FIG. 4, marginless thin tatami 2, walnut core plate with tatami facing is a thin Itadatami formed without the edges of flooring 1a~1d same thickness as of (10 a few mm), flooring During construction of 1a to 1d , the surface and the four surroundings are carried into the construction site in a state where the covering sheet is covered and protected with the curing sheet s.

  In the first step, as shown in FIG. 5, the first flooring 1 a is installed and fixed to the floor base 4. This fixing method is well known and will not be described.

  One side 1a1 of the first flooring 1a is linear in the direction of arrow A in the figure, and in the subsequent process, it becomes the reference side 1a1 for laying the other flooring 1b-1d and the tatami mat group 2A.

  Then, a tatami mat is formed by arranging four edgeless thin tatami mats 2 with a curing sheet s in a square shape by interposing a substantially L-shaped lower base material 5 of the parting material 3 on the reference side 1a1 of the first flooring 1a. The tatami mat group 2A is arranged in the tatami laying area in a state where the side 2A1 of the group 2A is aligned. In this case, the supporting vertical side portion 5b of the lower base material 5 is interposed between the first flooring 1a and the tatami mat group 2A, and the seat portion 5a of the lower base material 5 is the tatami mat group 2A as indicated by a broken line. And the floor base 4. In addition, the code | symbol of the parting material 3 is the same code | symbol in the following description. In the following process, the parting material 3 is interposed between the other flooring materials 1b to 1d and the tatami mat group 2A in the same manner as in the first process. Since it is not attached to the material 5, the reference numeral 3 (5) including the seat portion 5 a and the supporting vertical side portion 5 b is indicated.

  Next, in the second step, as shown in FIG. 6, in the tatami laying region, the lower base material 5 of the parting material 3 is interposed on one side 2A2 of the tatami mat group 2A in the same manner as described above. In the state where one side 1b1 of the second flooring 1b constructed at a position facing the first flooring 1a is directed to one side 2A2 of the tatami mat group 2A, the second flooring 1b is shown by an arrow B in the figure. Push in the direction, that is, in the direction of the first flooring 1a so that no gap is generated between the tatami mat group 2A and the second flooring 1b. The second floor material 1b is fixed to the floor base 4 in a state where the pushing is completed.

  Next, in the third step, as shown in FIG. 7, in the tatami laying region, the lower base material 5 of the parting material 3 is interposed on each side 2A3 of the tatami mat group 2A and each side 2A4 facing the side 2A3. In this state, the sides 1c1 and 1d1 of the third and fourth flooring materials 1c and 1d adjacent to the first and second flooring materials 1a and 1b are respectively directed to the sides 2A3 and 2A4 of the tatami mat group 2A. In this state, the third and fourth flooring materials 1c and 1d are pushed in relative directions (arrow C and D directions in the drawing) in the same manner as in the second step. The third and fourth floor materials 1c and 1d are fixed to the floor base 4 in a state where the pushing is completed.

  Next, in the fourth step, as shown in FIG. 8, since the first to fourth flooring materials 1a to 1d are fixed to the floor base 4, in this fixed state, the curing sheet s from the tatami mat group 2A. Is removed, the laying of the tatami mat group 2A in the tatami laying region is completed as shown in FIG.

  In addition, as shown in FIG. 9, you may assemble | attach the upper base material 6 with respect to the lower base material 5 of the parting material 3 as needed. This assembled state is indicated by reference numeral 3 (6). In this assembled state, the overhanging portion 6a of the upper base material 6 straddles the upper surfaces of the flooring materials 1a to 1d and the tatami mat group 2A, so that the gap between the flooring materials 1a to 1d and the tatami mat group 2A is hidden. Further, without assembling the upper base material 6, a spacer (not shown) may be interposed in the gap between the first to fourth flooring materials 1a to 1d and the tatami mat group 2A.

  Thus, in Embodiment 1, since the curing sheet s is affixed to the tatami mat 2A during construction of the floor coverings 1a to 1d, it is not necessary for the contractor to care about the dirt on the tatami mat 2A, and the floor coverings 1a to 1d. 1d construction becomes possible, and construction is easy to perform. Moreover, since the construction of the flooring materials 1a to 1d is performed in a state where the tatami mat 2A is laid, the construction error of the flooring materials 1a to 1d hardly occurs, and the flooring materials 1a to 1d in the state where the tatami mat 2A is laid. Since the construction of 1d is performed, the tatami laying area is secured in advance, and the tatami laying area is too narrow due to construction errors after the construction of the flooring materials 1a to 1d as in the past, so that the tatami mat group 2A cannot be laid. There is nothing. For this reason, since the tatami laying region is too narrow after the construction of the flooring materials 1a to 1d, it is possible to reduce labor and costs such as partly cutting the tatami group 2A or recreating the tatami group 2A.

(Embodiment 2)
In the first embodiment, only one side 1a1 of the first flooring 1a is the reference side. However, in the second embodiment, as shown in FIG. 10, one side 1a1 of the first flooring 1a is used as the first reference. One side 1c1 of the third flooring 1c adjacent to the side 1a1 is defined as a second reference side 1c1 that is linear, and the first flooring 1a and the third flooring 1c are disposed at a right angle. . In this state, the first floor material 1 a and the third floor material 1 c are fixed to the floor base 4.

  And after interposing the lower base material 5 of the parting material 3 in each of the 1st reference | standard side 1a1 of the 1st flooring 1a and the 2nd reference | standard side 1c1 of the 3rd flooring 1c, the curing sheet s The tatami mat 2A side 2A1, 2A3 is attached, and then the second flooring 1b is directed to one side 2A2 of the tatami mat 2A as indicated by a two-point phantom line in the same manner as described above. The first flooring 1a is pushed in, and when this pushing is completed, the second flooring 1b is fixed.

  Next, as shown in FIG. 11, in a state where the lower base material 5 of the parting material 3 is interposed on one side 2A4 of the tatami mat 2A, the fourth flooring 1d is indicated by a two-point phantom line of the tatami mat 2A. The fourth flooring 1d is pushed in the direction of the third flooring 1c in the same manner as described above in a state of being directed to the side 2A4, and when this pushing is finished, the fourth flooring 1d is fixed to the floor base 4. .

  As described above, when the construction of the flooring materials 1a to 1d is completed, when the curing sheet s is peeled from the tatami mat group 2A in the same manner as in FIG. 8, the laying of the tatami mat group 2A in the tatami mat area is completed as in FIG.

  According to the second embodiment, since one side of each of the first and third flooring materials 1a and 1c serves as a reference side, the laying work of the tatami mat group 2A is simplified as compared with the first embodiment.

  In the first embodiment, a wall or the like may be used as the casing instead of the first flooring 1a, and in the second embodiment, the first and third flooring 1a, 1c may be used as the casing. It may be a wall or the like.

  With reference to FIG. 12 and FIG. 13, the case where the 2nd parting material 3A different from the parting material 3 of Embodiment 1, 2 is used in Embodiment 1, 2 of this invention is demonstrated. FIG. 12 is a partially enlarged view of a state in which the parting material 3A is interposed between the flooring materials 1a to 1d and the tatami mat group 2A, as in FIG. FIG. 13A is a side view of the second parting material, and FIG. 13B is a perspective view of the second parting material. As shown in FIGS. 13 (a) and 13 (b), the second parting material 3A has a lower base 51 having a substantially L-shaped cross-section and a cross-sectional shape connected to the lower base 51 having an inverted substantially L-shape. An upper substrate 61. Each of the lower substrate 51 and the upper substrate 61 is configured by extruding a resin material that can be bent and deformed, and is used by cutting a long raw material that has been molded into a desired length.

  Since the lower base 51 is installed on the lower surface of the tatami mat group 2A, one end side extends in a horizontal direction that is the direction of the tatami mat group 2A and is wide and thin, and perpendicularly from the other end side of the seat section 51a. It is substantially L-shaped with the standing vertical side 51b. A groove 51c that opens upward is formed over the entire length of the base material in the supporting vertical side 51b, and a plurality of engaging portions in the vertical direction are formed at a constant small pitch on the opposing inner surface of the groove 51c. The sawtooth-shaped small protrusion 51d is formed over the entire length of the base material.

  When the upper base material 61 is connected to the lower base material 51, one end side projects in the other horizontal direction toward the upper surface of the flooring materials 1a to 1d, and the lower side vertically from the other end side of the overhanging part 61a. The connecting vertical side portion 61b extended in the shape is reversely substantially L-shaped. The connecting vertical side portion 61b is formed to have a thickness that can be inserted into the groove 51c of the lower substrate 51, and a plurality of connecting vertical side portions 61b are formed on both side surfaces of the connecting vertical side portion 61b at the same pitch as the small protrusions 51d. The sawtooth-shaped small protrusion 61c is formed over the entire length of the upper base 61 as an engaged portion.

  Further, the upper base 61 has an arc that hangs downward from the horizontal one direction, which is the tatami mat group 2A direction, to the vertical downward direction, preferably in an arc shape (1/4 circle) on the other end side of the overhanging portion 61a. An exterior vertical side portion 61d including a portion 61d1 and a vertical portion 61d2 extending vertically downward from the arc portion 61d1 is formed. The outer side surface of the vertical part 61d2 of the vertical side portion 61d for exterior and the outer side surface of the vertical side portion 51b for support of the lower base 51 are coincident in the vertical direction.

  In the second parting material 3A, the connecting vertical side portion 61b of the upper base member 61 is press-fitted into the groove 51c of the supporting vertical side portion 51b of the lower base member 51 from above, thereby reducing the small size of the connecting vertical side portion 61b. The upper base 61 is connected to the lower base 51 in a state in which the protrusion 61c engages with the small protrusion 51d of the supporting vertical side 51b and the upper base 61 is prevented from coming out of the lower base 51. It can be supported.

  Then, as shown in FIG. 12, when the second parting material 3A is interposed between the flooring materials 1a to 1d and the tatami mat group 2A, the shape of the circular arc portion 61d1 of the exterior vertical side portion 61d of the upper base material 61 is formed. The shape of the end portion of the tatami mat 2A is adapted, and the rounded appearance of the end portion of the edgeless thin tatami 2 is not obstructed by the second parting material 3A, and the tatami laying area can be comfortably and easily spent. .

  In addition, since the shape of the circular arc portion 61d1 of the exterior vertical side portion 61d of the upper base member 61 is rounded, the upper base member 61 does not catch a person in the tatami laying region. Can live comfortably in the area.

  Furthermore, since the shape of the arc portion 61d1 of the exterior vertical side portion 61d of the upper base 61 matches the shape of the end portion of the tatami mat group 2A, even if the tatami mat group 2A is seated in the tatami laying region, In the tatami mat group 2A adjacent to the materials 1a to 1d, the appearance of the shadow generated between the floor materials 1a to 1d, the edgeless thin tatami 2 and the edgeless thin tatami 2 adjacent thereto becomes natural, and the second parting There is no sense of incongruity due to the material 3A, and it is possible to live comfortably in the tatami laying area where the edgeless thin tatami 2 is laid.

  Further, a second parting material 3A is interposed between the flooring materials 1a to 1d and the tatami mat group 2A, and a spacer for eliminating a gap is interposed between the flooring materials 1a to 1d and the parting material 3A. However, since the spacer is concealed by the overhanging portion 61a of the upper base member 61, the appearance does not deteriorate even if the spacer is interposed, and it is comfortable in the tatami laying area where the edgeless thin tatami 2 is laid.
