〔Example〕

An embodiment in which a floor structure according to the present invention is formed on an existing floor base will be described in detail below with reference to the drawings. As shown in Figure 1, the existing subfloor consists of 2 large drawers, 3 joists, 4 insulation boards, 5 insulation materials, 6 rough tffE, and 7 toyotomi, and although not shown, the tatami mats are 7 and 7. They were formed at the same height.

The height HI of this tree 13 is formed lower than the height of the above-mentioned Toyotomi 7, and is approximately h/34H+. Toki 13
These are used to form a base for fixing reinforcing plates 18, which will be described later, and a space for forming mortar layer 16, and a plurality of plates are fixed in parallel at intervals above the existing subfloor. 1

Further, the thickness Ht satisfies HI>Hz, and has a thickness such that a mortar layer 16 to be described later is reliably formed on the heat insulating board 14, and a thickness that does not inhibit the function of the heat insulating board 14.

To explain in more detail, the heat insulating board 14 has one or more of the following functions: heat insulation, waterproofness, soundproofing, fireproofing, corrosion resistance, and dew condensation resistance. , nurate foam, vinyl chloride foam, inorganic reinforced plastic foam), rock wool board, gypsum board,

(Fe, etc.) or their alloys, general steel pipes with anti-rust treatment on the outer surface, or synthetic resins, and their cross-sectional shapes may also be triangular or square in addition to circular. etc. is optional. It is also possible to make the portion of the hollow pipe 15 in contact with the mortar layer 16 made of copper, and make the other circulation paths made of iron. Of course, by covering the portion of the hollow pipe 15 exposed to the outside air with a heat insulating material,
This prevents heat dissipation in areas other than the area where it is used. To explain in more detail, the hollow pipe 15 is arranged so that it does not protrude above the upper surface 13a of the tree 13 at the time of piping on the heat insulating board 14, and when the diameter of the hollow pipe is H2, H1≦ Due to the relationship between
6, the heat of the heat medium is uniformly dissipated to cool and heat the room according to the method α.

An example of the piping is as shown in FIG. 5(a) (mountain), and the piping can be freely set depending on the required part. In addition, A shown in Fig. 5 (a), mountain) is a heat medium supply device, which is a boiler that burns fuel such as oil, gas, or coal to heat and circulate antifreeze (ethylene glycol) or water. etc., or one or more of the following: underground water, indoor cooling, use of waste heat from heaters, heat pumps, heat pipes using geothermal heat, etc. A mortar layer 16 functions as a heat storage layer and a protective layer, and a hollow pipe 15 is filled in the space surrounded by the wood 13 and the heat insulating board 14. The mortar layer 16 is made by mixing an anti-freezing agent into the mortar in addition to the mortar used when forming the general outer wall to prevent the mortar from being destroyed by freezing and thawing in winter and damaging the hollow pipe 15. It is also possible to prevent this and increase the amount of aggregate (gravel, etc.) to further improve the heat storage effect. This mortar layer 16 is used for floor heating in winter and air conditioning in summer by the heat medium circulating in the hollow pipe 15, and the heat from the heat medium is stored in this mortar layer 16 and uniformly distributed. Heat is radiated toward the floor to uniformly cool and heat the room α. 17 is a protective sheet, which is laid over the entire floor surface after forming a mortar layer 16 between the trees 13, and is used to prevent moisture from entering under the floor and indoors α, and to serve as a reinforcing plate 1 to be described later.
Reinforcement plate 18 due to moisture rise from mortar layer 16 to 8
This is intended to simplify maintenance by preventing deformation of the reinforcing plate 18 and adhesion between the reinforcing plate 18 and the mortar layer 16. Its material is synthetic resin sheet (polyethylene,
PVC sheets, etc.). Reference numeral 18 denotes a reinforcing plate, which is rigid enough to protect the mortar JW 16 and the hollow pipe 15 against the load from above the floor, and any material with good thermal conductivity is sufficient. For example, it may be made of plywood or the like, and a protective sheet may be used. 17, and is fixed to the tree 13 using fixing tools such as nails to cover the entire floor surface. Reference numeral 19 denotes a tatami mat whose thickness is set according to the space surrounded by the reinforcing plate 18 and the abundant area 7. In addition, regarding the overall thickness relationship, the thickness of the reinforcing plate 18 is H4, and the thickness of the tatami mat 19 is Hs.
Then, the relationship is h#H+ +H4+H5.

Here, a construction method for a floor structure, for example a repaired floor structure, according to the present invention will be explained using FIGS. 1 to 5. First, remove the existing tatami to expose the existing subfloor. In addition,
The height of Toyotomi 7 was 62 mm. Therefore, the trees 13 with H+ = 20 m and W2 = 45n+ are fixed on the existing floor subsurface with P = 450 m corresponding to the plurality of joists 3. Next, a 10m heat insulating board 14 (polystyrene foam board) is laid and inserted into the space between the trees 13 without any gaps.In this case, the hollow pipe 15 to be constructed next is Hs = 15fl.
Since the hollow pipe 15 is sized to protrude above the wood 13 due to the diameter of φ, a concave portion with a depth of 511 mm is formed in the polystyrene foam board 14 as shown in the figure. Corresponding to the concave portion of the polystyrene foam plate 14 formed in this way, a Hs-15 crane φ
A hollow pipe 15 (copper pipe) is formed as shown in FIG. 5(a) to form a circulation path. After forming the circulation path using the copper vibrator 15a, next fill the space formed by the wood 13 with mortar of the same composition as that used for the outer wall until it is flush with the top surface 13a of the wood 13. , the hollow pipe 15 is buried in the mortar layer 16. Next, the entire surface of the mortar layer 16 is covered with a protective sheet 17 made of a polyethylene sheet, and then a reinforcing board 18 made of plywood with a thickness H4 = 12 m is fixed to the tree 13 with nails, etc., and placed over the entire floor. Set up Finally, the formation of the repaired floor structure is completed by placing a tatami mat with a thickness of 30 mm on the plywood 18.

According to the floor structure formed in this way, it is possible to create a renovated floor structure with added floor cooling and heating structures at the same height as Toyotomi 7, creating a comfortable living space, and preventing mold and mildew due to the condensation-resistant structure.
It has excellent anti-mite and anti-corrosion properties.
