It is preferable that the surface 11 of the flooring 1 at the upper end of the upper end face 2B is chamfered in the same manner as the male part 3 side. Moreover, it is preferable that the lower end of the lower cuff surface 4B below the female real part 5 is also shaped to be easily joined to the male real part 3 by chamfering.

In addition, about the shape of the male real part 3 and the female real part 5, in this Embodiment, the upper surface of the male real part 3 and the female real part 5 is formed in parallel with the lower surface of the flooring 1, and the male real part 3 and The lower surface of the female real part 5 is formed to be an inclined surface with respect to the lower surface of the flooring 1, but the shape of the male real part 3 and the female real part 5 can be as long as they can be fitted together. It is not limited to the embodiment.

  When the flooring materials 1 are joined together, a space 8 is formed above the joint of the male part 3 and the female part 5 by the recess 6A on the male part 3 side and the recess 6B on the female part 5 side. Is formed. The space 8 is located below the gap 7 formed between the surfaces 11 of the flooring 1.

  The sheet member 9 is provided in a space 8 formed by the opposite recesses 6A and 6B, and is disposed so as to block the gap 7 from below along the inner upper surface of at least one of the recesses 6A and 6B. As shown in FIG. 2, the sheet member 9 has a rectangular shape, and the longitudinal direction has the same length as the side where the male real part 3 and the female real part 5 of the flooring 1 are provided. In addition, the sheet member 9 has a shape that is bent in two in the lateral direction and the cross section is bent in a mountain shape. At this time, the sheet member 9 is preferably a flexible material so that the angle of the mountain shape can be deformed along the inner upper surfaces of the recesses 6A and 6B. For example, olefin, paper, resin, or the like is used. It is done. The thickness of the sheet is preferably 0.1 mm to 0.25 mm.

  The sheet member 9 in the present embodiment is provided separately from the floor material 1, and the vicinity of the top of the mountain shape is positioned in the gap 7 and is accommodated so as to close the gap 7. At this time, the sheet member 9 fills the gap generated in the gap 7 by opening the angle of the mountain shape along the shape of the recesses 6 </ b> A and 6 </ b> B by the restoring force of flexibility. Accordingly, the upper portions of the recesses 6A and 6B are preferably tapered so that the mountain shape of the sheet member 9 is provided along the recesses 6A and 6B. By closing the gap 7 from below using the sheet member 9, it is possible to close the gap 7 so as not to be noticeable with a simple structure without impairing the appearance of the surface 11 of the flooring 1.

  Moreover, it is preferable that the upper surface of the sheet member 9 is formed in the same color pattern as the surface decorative material 12 applied to the surface 11 of the flooring 1. By forming the surface 11 in the same manner as the surface 11 of the flooring 1, the gap 7 generated on the surface 11 of the flooring 1 is hardly recognized as the opening 7.

  The space 8 preferably has a triangular cross section, and the inner upper surfaces of the recesses 6A and 6B are formed as inclined surfaces 10A and 10B.

  For example, the inner upper surfaces of the recesses 6A and 6B are respectively formed as downward inclined surfaces 10A and 10B that are inclined upward from the male real part 3 and the female real part 5 toward the surface 11 of the flooring. The cross section of the space 8 is formed by the inclined surfaces 10A and 10B and the upper surface on the male part 3 side when joined, and has a triangular shape with the gap 7 as a vertex.

  Specifically, in the present embodiment, the upper end portions of the recess 6A provided on the male real part 3 side and the recess 6B provided on the female real part 5 side have the same height when joined. Formed to be. Further, the upper ends of the recesses 6A and 6B are formed at a position about one fifth of the entire thickness of the flooring 1 from the surface 11 of the flooring 1 so as to ensure the strength at the joint. Good. The upper surface of the sheet member 9 is disposed in the space 8 along the downward inclined surface 10A above the male real part 3 and the downward inclined surface 10B above the female real part 5 which are the inner upper surfaces of the recesses 6A and 6B.

  At this time, it is preferable that the sheet member 9 is made of an elastic material, and at least a part thereof is elastically in contact with the inclined surfaces 10A and 10B serving as the inner upper surfaces of the recesses 6A and 6B. For example, vinyl chloride resin or the like is used. Since the elastic restoring force due to the bending of the sheet member 9 works, the sheet member 9 is installed along the inner upper surface of the recesses 6A and 6B regardless of the angle of the mountain shape. Even if the gap 7 is displaced during joining or use, it can be deformed corresponding to the shape of the gap 7 or the space 8, and the gap 7 is closed without a gap.

  In addition, the shape of the cross section of the space 8 formed by the recesses 6A and 6B and the recesses 6A and 6B may be a shape as illustrated in FIGS.

The construction method of the sheet member 9 will be specifically described.
As shown in FIG. 1, the sheet member 9 is provided separately from the floor material 1. In the flooring 1, the male real part 3 and the female real part 5 are fitted and adjacently joined.

A space 8 is formed below the gap 7 formed between the surfaces 11 of the flooring 1 on both sides by the opposing recesses 6A and 6B. The space 8 extends along the inner upper surface of the recesses 6A and 6B. A flexible sheet member 9 that closes the gap from below is provided, and the sheet member 9 has a cross-sectionally bent shape and closes the gap 7 near the top of the mountain shape.

  Thereby, since the flooring 1 and the sheet | seat member 9 can be manufactured separately, the effort of the coating process at the time of flooring 1 formation can be reduced. Further, the gap 7 generated on the surface 11 of the flooring 1 is blocked from below by providing the sheet member 9 in the space 8 formed below the surface 11 of the flooring 1. It is possible to close the gaps 7 without conspicuous with a simple structure without impairing the appearance of the surface 11 of the first. In addition, since the sheet member 9 has a mountain shape and is flexibly disposed along the inner upper surfaces of the recesses 6A and 6B, the sheet member 9 is difficult to be removed even if a vacuum cleaner or the like is used once inserted.

  Thereby, since it can form in the aspect more integral with the surface 11 of the flooring 1, the conspicuousness of the space | gap 7 can be suppressed further.

  Further, in the space 8, it is preferable that the inner upper surfaces of the recesses 6A and 6B are inclined surfaces 10A and 10B, respectively, and the cross section is triangular.

  Thereby, the shape of the upper part of the sheet member 9 and the space 8 becomes the same mountain shape, and when the sheet member 9 is inserted into the gap, the surface of the mountain shape of the sheet member 9 and the recesses 6A and 6B. The inclined surfaces 10A and 10B, which are the inner upper surfaces, can be arranged in close contact with each other. Therefore, the gap between the sheet member 9 and the inclined surfaces 10 </ b> A and 10 </ b> B is reduced, and the sheet member 9 is stably disposed in the space 8.

Moreover, it is preferable that the sheet | seat member 9 is an elastic member, and at least one part is elastically contacting along inclined surface 10A, 10B.

  Thereby, when joined, the elastic restoring force can be installed along the shape of the space 8 regardless of the angle of the mountain shape, so even if the gap 7 is displaced at the time of joining or use, By deforming corresponding to the shape of the gap 7 and the space 8, the gap 7 can be closed without a gap.

  In addition, the sheet member 9 is preferably separated from the flooring 1 and accommodated in the space 8.

  Further, in the construction method of the floor material joint structure in the present embodiment, the sheet member 9 is elastically deformed so that the mountain shape is sandwiched, and is inserted into the space from the gap 7. 8 is deformed so that the mountain shape spreads by the elastic restoring force, and is constructed so as to be in a state along the inclined surfaces 10A and 10B.

  Thereby, after joining the flooring 1 or the flooring 1 that has already been used, it can be inserted later, and the sheet member 9 has to be inserted only at the location where the gap 7 is generated. Can be reduced.
