  By the way, for example, when the floor panel is thermally expanded and contracted, such as a resin-based floor panel, if the floor panel is completely restrained by the panel laying surface material, a part of the floor panel floats or the panel laying surface material On the other hand, problems such as warping may occur. However, it is necessary to regulate the movement of the floor panel in order to prevent the floor panel from shifting in the horizontal direction due to daily walking.

  Therefore, an object of the present invention is to provide a floor structure that can cope with thermal expansion and contraction of the floor panel and can prevent the floor panel from shifting.

  The floor structure of the present invention is a floor structure that extends from the building side to the outdoor side, and includes a panel laying surface material in which a protruding portion that protrudes upward is formed at a position close to the end portion on the building side, And a plurality of floor panels that are connected to each other and spread on the panel laying surface material, and are disposed on the projections of the floor panels. A restriction portion is formed on the lower surface of the substrate to surround the protrusion.

  The floor structure of the present invention is characterized in that the restricting portion is formed at a position spaced apart from both side surfaces in a direction orthogonal to the extending direction of the floor structure of the protrusion.

  The floor structure of the present invention is characterized in that the restricting portion abuts against a side surface of the protruding portion on the building side.

  The floor structure of the present invention is characterized in that the restricting portion is separated from the outdoor side surface of the protrusion.

  The floor structure of the present invention has a flat structure in which an opening that allows access to the floor structure from the inside is formed in the building, and there is no step between the indoor floor surface and the floor panel. It is a feature.

  In the floor structure of the present invention, the floor panel has a plurality of first ribs parallel to the floor structure extending direction and a plurality of second ribs orthogonal to the first rib. The restricting portion is characterized in that the first rib and the second rib are arranged so as to surround the protruding portion.

  According to the floor structure of the present invention, the protruding portion protruding upward is formed at a position close to the end of the panel laying surface material on the building side, and the restricting portion formed on the lower surface of the floor panel has the protruding portion. Since it is arranged so as to surround the protruding part, even when an external force that shifts horizontally on the panel laying surface material is applied to the floor panel, the restricting part is restricted by the protruding part to prevent excessive displacement of the floor panel Can do. Since the protruding part is formed at a position close to the end of the panel laying face material on the building side, the floor panel is most difficult to shift near the end on the building side, so there should be a gap between the floor panel and the building When moving between the indoor side and the floor panel side of the building, it is possible to prevent the toes from being stuck in the gap and the foot from being caught. Also, instead of restricting the movement of all floor panels, only the movement of the floor panel placed on the protrusions is restricted by the protrusions, so even if the floor panel expands and contracts, it will leave the building. Since the floor panel on the side can move in the horizontal direction according to the thermal expansion and contraction, the thermal expansion and contraction can be absorbed, and the floating and warping of the panel can be prevented.

  According to the floor structure of the present invention, since the restricting portion is formed at a position spaced apart from both side surfaces in the direction orthogonal to the extending direction of the floor structure of the protruding portion, the floor panel is a panel laying surface material. On the other hand, it is possible to move by a predetermined distance in a direction orthogonal to the extending direction of the floor structure, and to absorb thermal expansion and contraction in the direction orthogonal to the extending direction of the panel floor structure. Floating and warping can be prevented.

  According to the floor structure of the present invention, since the restricting portion abuts against the side surface on the building side of the protrusion, it is possible to reliably prevent the floor panel on the most building side from moving in the extending direction of the floor structure. It is possible to prevent a gap from being formed between the indoor side and the floor panel side of the building, and to prevent a foot from getting stuck in the gap and a foot from being caught.

  According to the floor structure of the present invention, since the restricting portion is separated from the outdoor side surface of the protruding portion, when the floor panel is laid on the panel laying surface material, the protruding portion is within the space surrounded by the restricting portion. Since the side surface on the building side of the projecting portion is in contact with the restricting portion, it is possible to improve the workability while preventing the generation of a gap between the floor panel and the building.

  According to the floor structure of the present invention, the building has an opening that allows entry into and exits the floor structure from the inside, and since the flat structure has no step between the indoor floor surface and the floor panel, Since there is no gap between the lower frame and the floor panel, the indoor floor surface can be moved smoothly from the floor panel, and it is possible to prevent the toes from being clogged or caught by the gap. it can.

  According to the floor structure of the present invention, a plurality of parallel first ribs and a plurality of second ribs orthogonal to the first rib are formed on the lower surface of the floor panel. Since it is formed by the second rib, the restriction portion is formed by using the lower surface rib originally possessed by the floor panel, and it is not necessary to newly form a member surrounding the projection portion.

The floor structure 1 is not limited to a cantilever balcony. For example, the floor structure 1 is an outdoor floor structure 1 such as a veranda, a balcony, or a terrace. The floor structure 1 extends from the building side B to the outdoor side O. Any floor structure 1 may be used. In this embodiment, “building side” refers to the side where the opening 2 of the building is provided in the horizontal direction when viewed from the floor structure 1, and “outdoor side” refers to the building side B viewed from the floor structure 1. The opposite side.

  As shown in FIG. 1, the floor structure 1 includes a floor frame 12 supported by a receiving plate 11 fixed to a building frame, a gradient floor unit 13 fixed on the floor frame 12, and a gradient floor unit 13. A large pull 14 provided on the end of the floor structure 1 and an end of the building side B, a panel laying surface material 3 laid on the large pull 14, and a panel laying surface material. 3 is a double floor provided with a plurality of floor panels 4 laid on top of 3.

  The “floor structure” in the present invention is not limited to a double floor structure, and may be a single floor structure in which the floor panel 4 is directly laid on a gradient floor. In such a single floor structure, the sloped floor constitutes the panel laying surface material in the present invention.

  In this embodiment, the panel laying face material 3 is a steel folded plate in which peaks and valleys are alternately formed. The panel laying face material 3 is fixed to the pulling 14 with screws. The panel laying surface material 3 is formed with a protrusion 5 protruding upward at a position close to the end of the floor structure 1 on the building side B. As shown in FIGS. 2, 4, and 5, the protruding portion 5 has a cylindrical shape, and the protruding height of the protruding portion 5 contacts the floor panel 4 when inserted between the regulating portions 6 of the floor panel 4. The diameter of the protrusion 5 is a dimension that can be inserted between the restriction portions 6 of the floor panel 4.

  As shown in FIGS. 3 and 4, the floor panel 4 is a decorative surface having a slightly uneven upper surface, and a plurality of first ribs 7 parallel to the lower surface along the extending direction of the floor structure 1, This is a resin-made rectangular face material on which a plurality of second ribs 8 orthogonal to the first ribs 7 are formed. As shown in FIGS. 5 and 6 (I), the first rib 7 and the second rib 8 formed on the lower surface of the floor panel 4 on the most building side B among the floor panels 4 surround the protrusions 5. Is configured. As shown in FIG. 5, the protruding portion 5 is disposed between the second second rib 8 and the third second rib 8 counted from the building side B of the floor panel 4 on the most building side B. The position of the protrusion 5 is not limited to this, and is preferably formed on the building side B at least more than the center line of the floor panel 4 on the most building side B.

  As shown in FIG. 6 (I), the restricting portion 6 is formed in a rectangular shape by two first ribs 7 and two second ribs 8. The first rib 7 of the restricting portion 6 is disposed at a position spaced a predetermined distance L1 from both side surfaces in a direction orthogonal to the extending direction of the floor structure 1 of the protruding portion 5. In this embodiment, the distance L1 from the protrusion 5 to the first ribs 7 on both sides of the restricting portion 6 is 9 mm. Thus, the distance L1 is opened between the first rib 7 of the restricting portion 6 and the protruding portion 5, so that the floor panel 4 expands and contracts in a direction perpendicular to the extending direction of the floor structure 1 by thermal expansion and contraction. Even if it is a case, the curvature between the 1st rib 7 and the projection part 5 absorbs the movement of the floor panel 4 by thermal expansion-contraction, and the curvature and the float of the floor panel 4 with respect to the panel laying surface material 3 can be suppressed.

  In addition, the second rib 8 disposed on the building side B of the protruding portion 5 is disposed on the second rib 8 of the restricting portion 6 so as to contact the side surface of the protruding portion 5. In this way, the second rib 8 on the building side B abuts on the protruding portion 5, so that the floor panel 4 moves in the extending direction of the floor structure 1 and a gap is formed between the floor panel 4 and the building. Therefore, when moving between the indoor side of the building and the floor panel 4 side, it is possible to prevent the toes from being stuck in the gap and the foot from being caught. And since the 2nd rib 8 arrange | positioned in the outdoor side O of the projection part 5 among the 2nd ribs 8 of the control part 6 is arrange | positioned so that the distance L2 may be opened and spaced apart from the side surface of the projection part 5, When the panel 4 is laid, the projecting portion 5 is easily inserted into the space surrounded by the restricting portion 6, so that the workability is excellent.

  The floor panel 4 of the present invention is not limited to resin, and for example, the upper surface may be formed of porcelain tile, natural stone, wood or the like. On the lower surface of the floor panel 4, a diagonal rib 9 having a protruding length shorter than that of the first rib 7 and the second rib 8 is formed in a part of a diagonal line between the first rib 7 and the second rib 8. When the floor panel 4 is placed on the panel laying surface material 3, the first rib 7 and the second rib 8 are provided with a convex portion 21 that comes into contact with the upper surface of the panel laying surface material 3, rainwater, and the like. Recesses 22 that are recessed so as to become water flow paths when flowing on the material 3 are formed.

  In addition, on two adjacent sides of the outer peripheral edge of the floor panel 4, a female connecting portion 10a formed in an annular shape penetrating in the vertical direction is formed extending laterally. Moreover, the male connection part 10b protrudes and is formed in the position corresponding to the female connection part 10a of the remaining 2 sides. The adjacent floor panels 4 are connected by inserting the male connecting portion 10b into the female connecting portion 10a. The “connecting portion” in the present invention corresponds to both the female connecting portion 10a and the male connecting portion 10b.

  In the building where the floor structure 1 extends, an opening 2 is formed at a position adjacent to the floor structure 1, and the floor structure 1 can be entered and exited through the opening 2 inside the building. In the present embodiment, the opening 2 is a sliding sweep-out window, but is not limited thereto, and may be a hinged door, a folding door, etc., as long as it can enter and exit the floor structure 1 from inside. Such an opening 2 may be used. In this embodiment, it has a flat structure with no step between the indoor floor 15 and the floor panel 4. That is, the indoor floor 15 and the top surface of the floor panel 4 are substantially flush with each other, and the lower frame 2a of the opening 2 has a shape that hardly protrudes from the height of the indoor floor 15 and the top surface of the floor panel 4. Is formed. By adopting such a flat structure, a child or the like can easily enter and exit the floor structure 1 from the inside. However, as described above, the protrusion 5 and the second rib 8 on the building side B of the protrusion 5 The contact prevents the gap between the floor panel 4 and the building, so that it is possible to prevent the toes from being stuck in the gap and the foot from being caught.

  When the floor panel 4 is laid down on the panel laying surface material 3, as shown in FIG. 4, the floor panel 4 closest to the building B among the floor panels 4 is placed on the lower surface of the floor panel 4 with the first rib 7 and the second rib. The floor panel 4 is placed on the panel laying surface material 3 so that the protrusion 5 is inserted into the space surrounded by the restriction portion 6 formed by the ribs 8. Then, the floor panel 4 is further placed on the panel laying surface material 3 so as to be adjacent to the floor panel 4 on the building side B most. At this time, as shown in FIGS. 6 (II) and 7, the male connecting portion 10b of the floor panel 4 adjacent to the female connecting portion 10a of the floor panel 4 is inserted and the adjacent floor panels 4 are connected to each other. As for the connection part of the female connection part 10a and the male connection part 10b, the hole of the female connection part 10a is formed larger than the male connection part 10b, and between the inserted male connection part 10b and the inner surface of the female connection part 10a. There is an interval to allow for play P between them. As a result, the floor panels 4 connected adjacent to each other are connected so as to be able to approach and separate from each other within the range of the play allowance P.

  Therefore, the thermal expansion and contraction of the floor panel 4 can be absorbed even by the allowance P between the male connecting portion 10b and the female connecting portion 10a, and a large gap can be formed at the periphery of the floor structure 1 on which the floor panel 4 is laid. Can be prevented.

  Needless to say, the embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the idea of the present invention.

  The floor structure 1 which concerns on this invention can be used suitably as the floor structure 1 which comprises the floors of outdoor parts, such as a balcony, a veranda, a terrace, for example.
