Description of the Related Art As shown in FIGS. 11 to 16 of Japanese Patent Publication No. 7-86261, in the case of a wooden house having a basement and a semi-basement, an underground foundation is constructed by a wooden floor structure. Alternatively, means for assembling a wooden floor on slab concrete has been employed. Of these, on the floor facing the outside such as a garage, it is known that there is concern about airtightness and heat insulation, especially in the above wooden floor structure, and the occurrence of accidents due to exhaust gas is a problem. Has been. As a solution to these problems, floor construction means for assembling a wooden floor on slab concrete and laying a heat insulating material is known. With this construction means, although airtightness is improved, in order to carry out regenerative floor heating, it must be carried out on a wooden floor, which requires not only a complicated structure but also a long time for construction. Even if slab concrete is used as the heat storage body, the heat storage body does not effectively exhibit the heat storage function unless a large number 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 insulation structure, an airtight structure, a heat storage structure, or the like. In view of such prior art, the construction of large floors in buildings, especially underground foundations of wooden buildings, is avoided, and heat insulation structures, airtight structures,
An invention aimed at easily implementing a heat storage structure or the like is known from Japanese Patent Publication No. 7-86261.

[0003] The invention described in this publication is proposed by the present inventor. The foundation is fixed on slab concrete, foam insulation is laid at intervals, and the foam insulation is laid around the foundation. A foam sheet is placed on the base and the foam insulation is injected into the gap between the foam insulation and the gap between the foam insulation and the base. The present invention relates to a floor construction method for a building, characterized in that a floor rebar is arranged on a foamed heat insulating material, and concrete is cast and leveled. The invention described in this publication can be said to be an excellent invention in that it can solve the problems of the above-mentioned conventional technology (the conventional technology for large-scale floor construction). Since the heat insulating material formed into a substantially C-shape that spreads downwards is used, the heat insulating material is laid on the slab concrete while forming a V-shaped arrangement interval between the foamed heat insulating materials (FIGS. 4 and 5). It has been found that a foam insulation material having a new special shape, which has never been seen before, has to be molded, and the molding takes an unexpected time and cost, and should be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Claims 1 and 2 will be described with reference to FIGS. In the case of having a garage G (shown in FIG. 1) or a boiler room, a warehouse, a refrigerator, an insulated box, and other basement or semi-basement, it is constructed of slab concrete which serves as a ceiling of the basement or semi-basement and a floor of a building. The base 2 is mounted and fixed on the flat surface 1 by means of anchor bolts (not shown), bolts or other fixing means.

The flat surface 1 is not only constructed of the above-mentioned slab concrete. If a basement, a semi-basement, etc. is not constructed, foamed concrete, deck plate, wood base, slab concrete, compacted gravel, etc. It is possible to build with. Then, columns 12, studs (not shown) and the like are erected on the base 2.

Next, a foamed heat insulating material 3 previously formed into a plate shape
(For example, a foamed polystyrene plate having a thickness of about 100 mm,
Other foamed resin plates) are laid on the flat surface 1, and the foam heat insulating material 3 is a heat insulator formed by forming the entire peripheral surface and the upper surface and the lower surface at right angles, and between the foam heat insulating materials 3 on the flat surface 1. Spacer 4 is arranged to arrange the space 5 of equal width in the front, rear, left and right directions.
(E.g., a width of 10mm position) as well as laid while forming, arrangement intervals equal dimension width in the longitudinal <br/> lateral direction by arranging a spacer 4 also between the base 2 5 (e.g., the 10mm position Width) is formed and laid.

The spacer 4 is a member used for easily forming the arrangement interval 5 of a predetermined size to improve the workability. The spacer 4 is made of wood, metal, plastic, stone, or any other material of square or circular shape. , Molded into other polygons, etc.
Those having the same width dimension or the same diameter dimension are arranged between the foamed heat insulating materials 3 and between the heat insulating material and the base 2 so as to form an arrangement interval 5 having an equal width in the front , rear, left and right directions. The means for arranging the spacers 4 is simply arranged, so that the arranging portion can be corrected later, or the spacer 4 can be adhered and fixed to the flat surface 1, and can be freely selected. Select and decide in consideration of conditions.

After the foam insulation 3 has been laid, the pillar 12,
A moisture-proof sheet 6 (for example, a polyethylene resin film or another resin film) is stretched under a stud (not shown) or the like, that is, on the side of the foam insulation material laying around the base 2,
It is attached and fixed to the lower part of the column 12, the lower part of the stud (not shown), the base 2 and the like by appropriate fixing means such as nailing and bonding. The moisture-proof sheet 6 is made of the moisture of the concrete 10 described below,
Although it is a member for preventing moisture and the like from outside the building, it is not always necessary to dispose it.

Next, an interval 5 between the foamed heat insulating materials 3 is set;
An in-situ foaming heat insulating material 7 (for example, a foamed polyurethane foam or other in-situ foaming resin) is injected into the space 5 between the foamed heat insulating plate 3 and the base 2 and foamed to form a heat insulating layer. When this is completed, the weir plate 8 (about 80 mm in height) is provided above the foamed heat insulating material 3 on the foamed heat insulating material laying side surface such as below the pillar 12 and below the stud (not shown).
The concrete 10 to be described later is
Between the stud and the stud (not shown). Next, a floor reinforcing bar 9 (for example, a wire mesh having a diameter of about 3.2 mm) is placed on the laid foam insulation material 3, concrete 10 is cast, and the surface is leveled to finish the construction.

When the moisture-proof sheet 6 is not provided, the base 2
Moisture-proof means shall be applied to the surrounding outer surface. In the above-described process, if the laid foam insulation material 3 becomes uneven, it is temporarily removed, sand (not shown) is laid on the flat surface 1, and then laid again so as to be flush. .

The reason why the entire peripheral surface and the upper and lower surfaces of the foamed heat insulating material 3 are formed at right angles is to avoid molding into a special shape such as the foamed heat insulating material disclosed in Japanese Patent Publication No. 7-86261. In order to make it possible to use together with a well-known foam insulation material in which the surface and the upper surface and the lower surface are formed at right angles or to use the well-known product alone, and to facilitate and procure parts easily, This is also to reduce costs. When the in-situ foamable heat insulating material 7 injected into the arrangement interval 5 rises higher than the laid foamed heat insulating material 3, the raised portion is cut to make the surface flush.

The length dimensions of each member in the above embodiment,
The thickness dimension and other dimensions are merely examples of easy-to-handle dimensions, moderate dimensions that do not impair the heat insulation function, airtight function, and the like, and are not limited thereto. Then
The above steps can be modified as follows. Fixing the base 2 on the flat surface 1 → disposing the moisture-proof sheet 6 → laying the foam heat insulating material 3 on the flat surface 1 → injecting the foam heat insulating material 7 in the arrangement interval 5 → the dam plate Installation of 8 → Arrangement of the floor reinforcing bar 9 → Casting of concrete 10.

Claim 2 will be described with reference to FIG. The steps up to the step of arranging the reinforcing bar 9 in the first embodiment are the same as those in the first embodiment.
When the reinforcement of the floor reinforcement 9 is completed, a heating pipe 11 (either a metal pipe or a synthetic resin pipe) may be piped onto the floor reinforcement 9, concrete 10 may be poured in, and the surface may be leveled out. end.
Although not shown, the weir plate 8 is mounted on the base 2 between the pillar 12 and the stud (not shown), and the moisture-proof sheet 6 is attached to the pillar 12,
The studs (not shown), the weir plate 8 and the base 2 are arranged on the side of the foam insulation material laying.

[0016]

Since the present invention has been configured as described above,
The following effects are obtained. Avoiding molding into the same shape as the specially-shaped foam insulation material described in the publication, and using a foam insulation material formed by forming the upper surface and the lower surface and the entire peripheral surface at right angles, the molding of the heat insulation material At the same time as the time is significantly shortened, the molding cost is significantly reduced, as well as the advantage of foam insulation molding, in terms of application or usage,
Since it is possible to use together with a well-known foam insulation material whose upper and lower surfaces and the entire peripheral surface are formed at right angles, the ease and reliability of material procurement are increased, and flooring is inexpensively performed while improving work efficiency. Can be constructed. Since placing a spacer between the foam insulation and between the heat insulation material and the base, etc. dimensions of predetermined width
It is possible to easily and quickly form an arrangement interval having a width . Therefore, it is possible to efficiently inject the in-situ foamable insulating material into the arrangement intervals without worrying about injecting the foamable insulating material, and to form the heat insulating layer with good workability.

The spacers are formed from various materials such as wood pieces, metal pieces, plastic pieces, and stone materials.
It is convenient and can be used easily and in large quantities without causing cost increase. Since a wooden floor group is not used, labor can be saved, and a heat insulation structure, an airtight structure, a heat storage structure, and the like can be efficiently and easily performed. Since a moisture-proof sheet was placed around the base,
It is possible to prevent disadvantages such as corrosion around the base due to moisture and mold generation due to moisture around the base. By injecting in-situ foaming insulation into the spaces between the foam insulation and the space between the foam insulation and the base, even if there is a basement or semi-basement, heat bridges from them can be prevented. Is not cooled, and the heat insulation performance is improved. Even if the slab concrete is uneven, a level can be obtained at the time of installing the weir plate, so that the floor completed by the final concrete casting can be easily leveled.
