[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a floor construction method for constructing wooden buildings, prefabricated houses and concrete buildings. Particularly, when a basement or semi-basement is constructed, the basement or semi-basement is used. The present invention relates to a floor construction method that exhibits airtightness, heat insulation, etc.

[0002]

[Prior Art and Problems] In the case of a wooden house having a basement or a semi-basement, the basement of the basement is an underfloor structure (see FIG. 11).
(Fig. 12) or a means for assembling a wooden floor on slab concrete (Fig. 13). Of these, in the floor facing the outside such as a garage, it is known that there is anxiety about airtightness and heat insulation particularly in the above-mentioned wooden floor structure, and an accident caused by exhaust gas is a problem. Has been As a solution to these problems, there is known a floor construction means in which a wooden floor is assembled on slab concrete and a heat insulating material is laid (see FIGS. 14 and 15). Although the airtightness is improved by this construction means, in order to carry out the heat storage type floor heating, it is necessary to carry out on the wooden floor, and not only the complicated structure but also the construction takes time. Figure 1
Even if the slab concrete shown in FIG. 3 or FIG. 16 is used as the heat storage body , the heat storage body does not exhibit its heat storage effect effectively unless a large amount of heat insulating plates are provided under the floor and under the foundation.

Even if any of the above-mentioned construction means is adopted, it is difficult to easily form a heat insulating structure, an airtight structure, a heat storage structure, or the like.

The present invention has been made to solve the above-mentioned problems, and eliminates the construction of wooden floors in an underground foundation of a building, particularly a wooden building, and has a heat insulating structure, an airtight structure, a heat storage structure, etc. The purpose is to be able to easily install.

[0005]

[Means for Solving the Problems] Means for achieving the above-mentioned object of the present invention is to fix a foundation on slab concrete and to lay a foam insulating material at an arrangement interval, A moisture-proof sheet is placed on the side of the foam insulation, and the on-site foam insulation is injected into the space between the foam insulation and the space between the foam insulation and the base. Install the weir plate from the sheet surface, then arrange the floor reinforcing bars on the foam insulation, level the concrete by placing it, and fix the foundation on the slab concrete, and place the foam insulation at intervals. Install a moisture-proof sheet on the side of the foam insulation around the base, and inject the on-site foam insulation into the space between the foam insulation and the space between the foam insulation and the base.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Claim 1 will be described with reference to FIGS.

Boiler room B and / or garage G (see FIG. 1)
In the case of a warehouse, refrigerator, cold storage, or other basement or semi-basement, the base 2 is anchor bolts (not shown) on the slab concrete 1 that serves as the ceiling of the basement or semi-basement and the floor of the building. ),bolt,
Attach and fix with other fixing means. Then, the pillars 12, the studs 13 and the like are erected on the base 2. Next, the foamed heat insulating material 3 (for example, a thickness of 100 mm, which is formed in a plate shape in advance, is used.
Position of expanded polystyrene plates, but the other of the foamed resin sheet) is laid concrete slab on 1, foam insulation 3 is substantially entire peripheral surface spreads according leads on one side (the other side from the top) (downward) Insulation material shaped like a letter V, with V-shaped spacing 4 between foam insulation materials on slab concrete 1
And the base 2 are also laid while forming a substantially V-shaped arrangement interval 6 between them. After laying the foam insulation 3, lower the pillars 12, studs 13, etc.,
That is, the moisture-proof sheet 5 is provided on the side surface of the foam insulating material laid around the base 2.
(For example, a polyethylene resin film or other resin film) is stretched around, and is attached and fixed to the lower part of the pillar 12, the lower part of the stud 13, the base 2 or the like by an appropriate fixing means such as nailing or adhesion. The moisture-proof sheet 5 is a member for preventing the moisture of the concrete 10 described later, the moisture from the outside of the building, and the like. Next, in-situ foaming heat-insulating material 7 (for example, foamed polyurethane foam or other in-situ foaming resin) is injected into the arrangement interval 4 between the foam insulation materials 3 and the arrangement interval 6 between the foam insulation plate 3 and the base 2. Then, foam it to form a heat insulating layer. Once this is done, on the foam insulation laying side, such as below the columns 12, below the studs 13,
Barrier plate 8 (height 80 mm above the laid foam insulation 3)
The concrete 10 to be described later is blocked from flowing into the space between the columns 12 and 13 studs. Next, floor reinforcing bars 9 (for example, wire mesh having a diameter of about 3.2 mm) are placed on the laid foam insulation material 3, concrete 10 is cast, and the surface is leveled to finish the construction.

[0008] In the above process, when Furiku the foam insulation 3 which is laid occurs, once removed, on concrete slab 1 and re-laid after have laid sand (not shown), align flush To do so. Further, the reason why the entire peripheral surface of the foamed heat insulating material 3 is formed in a substantially V-shape is that the lower parts abut each other during the laying work to improve workability, and the arrangement intervals 4, 6
This is to enhance the heat insulating property by allowing the in-situ foaming heat insulating material 7 to be injected therein. When the in-situ foaming heat insulating material 7 injected into the arrangement intervals 4 and 6 rises higher than the laid foaming heat insulating material 3, the rising portion is cut to make the surface flush.

The length dimension of each member in the above embodiment,
The thickness dimension and other dimensions are examples of dimensions that are easy to handle, moderate dimensions that do not impair the heat insulating function, airtight function, and the like, and are not limited thereto.

However, the above steps can be modified as follows.

Fixing the base 2 on the slab concrete 1-> disposing the moisture-proof sheet 5-> laying the foam insulation 3 on the slab concrete 1-> injecting the on-site foam insulation 7 into the arrangement intervals 4, 6. -> Install the dam plate 8-> Place the floor rebar 9-> Place concrete 10.

Claim 2 will be described with reference to FIG.

The steps up to the step of arranging the floor reinforcing bar 9 of claim 1 are the same as those of claim 1.

When the arrangement of the floor reinforcement 9 is completed, the heating pipe 11
(Metal tube or synthetic resin tube may be used) is laid on the floor rebar 9, concrete 10 is placed, and the surface is leveled to finish the construction.

By the way, in the above two embodiments, a part or all of the peripheral surface of the foamed heat insulating material 3 is formed by molding at right angles to the upper surface and the lower surface (see the foamed heat insulating material 3 on the right side of FIG. 10). , entire circumference if laid in combination with V-shape prior Symbol foam insulation 3, it is possible to make the arrangement interval 4,6 substantially V-shaped is formed. As shown in FIG. 10, the dam plate 8 is mounted on the base 2 between the pillar 12 and the stud 13, and the moisture-proof sheet 5 is attached to the pillar 12, the stud 13, the dam plate 8, and the base 2.
It is installed on the side of the foamed heat material laid.
