The gist of the floor structure for solving the above problems is that the floor base material is installed on the upper surface of the slab in the reinforced concrete structure via the uneven surface adjusting material, and the finishing board is laid on the upper surface of the floor base material. In addition, the position of the upper surface of the floor base material is aligned with the reference ink that is blacked on the wall surface on which no joists are installed, and at the end of the long side of the floor base material near the wall or in the vicinity of the end. A pier to be reinforced in place of the joists along the way. In addition, a gap for preventing resonance is provided between the floor base material on the wall and the wall surface, and the end of the finish plate laid on the floor base material is also prevented from being deformed between the wall surface. A gap portion is provided, and the gap portion is closed by a baseboard and an airtight piece installed on the wall surface. Furthermore, on the wall surface along the short side direction orthogonal to the pier of the floor base material, a reinforcing floor base material having a gap portion between the wall surface and having a pier at the upper part is installed via a non-land adjuster. The top surface of the reinforcing floor base material is matched with the reference black provided on the wall surface. Further, the reinforcing pier at the wall includes that it is at least the same width as the other piers.
The gist of the construction method of the floor structure according to the present invention is that a floor-level reference ink is printed on the wall surface of a dwelling unit in a reinforced concrete structure, the upper surface is aligned with the reference ink, and a clearance for preventing resonance is provided from the wall surface. The floor pier is installed along the edge of the long side of the floor base material near the wall or near the end, and the wall pier to be reinforced instead of the joist is at least the same width as other piers. A finishing board is laid on the floor base material by providing a gap for preventing deformation between an end of the finishing board and the wall surface, and a baseboard and an airtight piece installed on the wall surface; To close the gap. In addition, a reinforcing floor base material having a pier at the upper part is installed along the wall on the wall in the short side direction perpendicular to the pier provided along the end on the long side of the floor base material. In addition, after the upper surface of the floor base material for reinforcement is installed through the uneven surface adjusting material in accordance with the reference ink, another floor base material is installed and then a finishing plate is laid.

  A floor structure that does not require a joist can be provided by arranging the floor base material so that the upper surface is aligned with the reference ink printed on the wall surface. In addition, the pier on the wall side of the floor base material is installed at a position slightly away from the end or the end, so that the strength of the end of the floor base material near the wall can be increased. Become. In addition, when the wall of the floor base material is perpendicular to the wall of the floor base material, a reinforcing floor base material is installed along the wall between the floor base material. By installing, the edge part of the floor base material in the wall of a floor base material at the orthogonal | vertical direction with the crosspiece of a floor base material can be reinforced. In addition, by installing the floor base material with the upper surface aligned with the reference ink printed on the wall surface, the installation work of the joist before installing the floor base material can be omitted, so that workability can be improved.

In addition, since the process of installing the reinforcing floor base material on the wall in the direction orthogonal to the pier of the floor base material can be performed by one person, workability can be improved.

  Hereinafter, embodiments of the floor structure and the construction method of the present invention will be described. First, the floor structure will be described, and then a method for constructing the floor structure will be described. In each embodiment, the same components are described with the same reference numerals, and different configurations are described with different reference numerals. .

  In this floor structure, a floor base material made of foamed resin is installed on the top surface of the slab in each dwelling unit of a reinforced concrete apartment house. Rather than installing as a reference level, a reference ink painted on the wall surface is set as a reference level for the floor.

  FIG. 1 shows a floor structure 1 according to a first embodiment. This floor structure 1 is configured by installing a floor base material 3 made of foamed resin on a top surface of a slab 2 via a non-land surface adjusting material 4 such as mortar and laying a finishing plate 5 on the top surface.

  This floor base material 3 is a flat rectangular thermoplastic foam resin composite, and has a density of 8 to 40 g / l, high density polyethylene, linear low density polyethylene, polypropylene, propylene / ethylene copolymer, styrene / polyethylene copolymer. It is made of polystyrene resin such as coalescence, polyolefin resin, or urethane resin. A hard thermoplastic foam resin pier 6 is embedded on the upper surface, and a finishing plate 5 is nailed.

  The base black 8 in which the floor base material 3 is blacked on the wall surface 7 is set as the reference level of the floor surface. This is installed by aligning the upper surface of the floor base material 3 with the reference ink 8 on the four wall surfaces 7 of each room (so that the upper surface of the floor base material and the reference ink are in the same position). Install at the same procedure and level as if installed.

The pier 6 is installed along the long side direction of the floor base material 3, and the pier 9 in the floor base material 3 near the wall is set closer to the edge on the long side than the pier 6 of the other floor base material. Has been. Also, as shown in FIG. 1, the width of the pier 9 is the same as the width of the other piers 6. This is because the pier 9 replaces the joist and reinforces the end on the long side of the floor base material 3 near the wall.

  These floor base materials 3 are overlapped at the fitting step 10 at the end on the long side, and the floor base material 3 near the wall is not abutted against the wall surface 7 but has a slight gap 11 between the wall surface 7. is set up. Further, the end portion of the finishing plate 5 is not abutted against the wall surface 7 but is slightly separated from the wall surface 7 (with an appropriate gap portion 22). The gap portion 22 is closed with the soft airtight piece 13 of the baseboard 12. And the design is also convenient. The reason why the floor base material 3 is slightly separated from the wall surface 7 in this way is to prevent the floor from resonating. The reason why the finishing plate 5 is slightly separated from the wall surface is to prevent the wooden finishing plate 5 from being deformed into a convex shape due to expansion due to moisture absorption.

  Therefore, in this floor structure 1, all four sides of the lower floor 14 formed of the floor base material 3 are formed slightly apart from the wall surface 7. That is, the floor base material 3 near the wall is installed slightly away from the wall surface 7. In addition to installing the floor base material 3 near the wall away from the wall surface 7 in this way, a floor structure in which the floor base material 3 near the wall abuts against the wall surface 7 can also be used.

  FIG. 2 shows a floor structure 15 according to the second embodiment. In this floor structure 15, the pier 9 on the wall on the upper surface of the floor base material 3 is formed wider than the other piers 6, and the other configuration is the same as the floor structure 1 of the first embodiment described above. It is. When the pier 9 near the wall is widened, the end of the floor base material 3 at the wall is reinforced instead of the joist. This width may be more than twice the other pier 6 and less than twice.

  FIG. 3 shows a floor structure 16 according to the third embodiment. This floor structure 16 is constructed by installing a pier 9 near the wall on the upper surface of the floor base material 3 at the edge on the long side of the floor base material 3, and other than this, the floor structure 1 of the first embodiment described above. It is the same composition as. This is not a position slightly separated from the end edge as described above, but is provided at the end edge to reinforce the end portion of the floor base material 3 at the wall instead of the joist. Further, the width of the pier 9 may be the same as that of the other piers 6, or may be twice or more and twice or less.

  FIG. 4 shows a floor structure 17 according to the fourth embodiment. This floor structure 17 has a floor base material 19 for reinforcement having a base 18 installed on the upper surface along a wall at a wall perpendicular to the base 6 of the floor base material. It is the same structure as the floor structure 1 of 1 embodiment. The end portion of the floor base material 3 on the short side is reinforced by the crosspiece 18 of the floor base material 19 for reinforcement. That is, the end on the long side is reinforced with the pier 9 along the wall surface, while the end on the short side is reinforced with the reinforcing floor base material 19, so that the lower floor formed of the floor base material 3 is used. Thus, piers 6 and 18 are installed around 14. Since the reinforcing floor base material 19 can be installed by the same procedure as the other floor base material 3 in the same procedure, the workability is improved. The pier 18 can also be formed wider than the pier 6 of the floor base material 3.

Moreover, although said embodiment demonstrated the normal concrete slab, this may be a hollow slab. In addition, a damping surface material (not shown) such as an asphalt sheet or a rubber sheet having a surface density of 9 kg / m ² or more is installed on the upper surface of the floor base material 3 via a woody material such as plywood or particle board. It may be a thing. In addition, the floor base material 3 has a low-foaming high-density portion whose upper part is made of polystyrene resin, polyolefin-based resin, urethane resin, or the like, and a high-foamed low-density portion whose lower part is made of an elastic closed-cell thermoplastic foamed resin. (Not shown). Further, a foam resin heat insulating plate may be attached to the wall inner surface, or a foam resin heat insulating plate may be attached to the lower surface of the slab 2, that is, the ceiling surface of the lower floor (see FIG. Not shown).
