Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure under a floor of a house or the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a basic structure of a house or the like has a concrete base part 1 standing upright along the outer peripheral shape of the house and corresponding to a wall position of a room or the like inside thereof. Then, a concrete foundation 1 is erected.
On the soil surface inside these foundation portions 1, a soil portion 2 made of concrete is provided to prevent moisture.

Further, after the foundation work is completed, in order to perform floor assembly, a plurality of concrete slabs 3 are installed on the soil part 2 at regular intervals, and the upper surface of each slab 3 has a basic height. A wooden floor bundle 4 that is substantially the same as the section 1 is erected, and a floor frame such as Daihiki and joist is erected on the floor bundle 4 and a base (not shown) installed on the foundation portion 1, and the floor board I am trying to put up.

[0004]

However, in the conventional floor structure, since the wooden floor bundle 4 is erected on the bundle stones 3, the floor bundle 4 is caused by the vibration of the building such as an earthquake or a typhoon. There is a risk of slipping or falling. Therefore, it is necessary to fix the floor bundle 4 to a haul or the like by using a diagonal member such as a root clasp.
If there is diagonal material, the underfloor cannot be used effectively, and there is a problem that it is difficult for a worker to dive under the floor during maintenance.

Further, in the wooden floor bundle 4, it is necessary to arrange a large number of the wooden floor bundles with a narrow arrangement interval in order to secure the strength to support the floor surface, which causes a problem in terms of economical efficiency and workability. The floor is small and there is a problem in terms of maintenance.

Furthermore, since the wooden floor bundle 4 is located close to the soil surface, it is liable to be harmed by the presence of white and the like, so it is necessary to inject or spray a special chemical agent or the like onto the floor bundle 4. It is necessary to perform insect repellent treatment regularly after construction.

The present invention has been made in view of the above points, and secures safety by making a floor bundle strong against earthquakes, vibrations, etc., and minimizes the number of floor bundles to be installed. It is therefore an object of the present invention to improve the economical efficiency and the workability as well as to improve the maintainability, and to provide a floor structure capable of preventing the damage such as whiteness without performing insect repellent treatment.

[0008]

According to the present invention, a concrete foundation portion 11 is erected along the outer peripheral shape of a floor surface, and a concrete soil portion 13 is provided on the soil surface inside the foundation portion 11.
Is laid, a concrete floor bundle 14 is erected on the soil portion 13 integrally with the soil portion 13, and a floor frame 17 for supporting the floor surface is erected on the foundation portion 11 and the floor bundle 14. .

[0009]

According to the present invention, by using the concrete floor bundle 14, concrete is placed on the floor bundle 14 at the same time as the foundation portion 11 and the like during foundation work, and the floor bundle 14 is erected integrally with the soil portion 13. To do. Since the concrete floor bundle 14 is erected integrally with the soil part 13, it is resistant to vibration of the building during an earthquake or typhoon, and the installation interval is wide to reduce the number of installations.
It is possible to prevent harm such as whiteness without applying insect repellent treatment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of an embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a perspective view of a part of the completed foundation work of a house, and FIG. 2 is a plan view of the entire structure. A concrete foundation part 11 is erected along the outer peripheral shape of the house. At the same time, a concrete foundation 11 is erected inside the wall corresponding to the wall position of a room or the like. A plurality of anchor bolts 12 (only a part of which are shown) are planted on the upper surface of the foundation portion 11.

A concrete soil portion 13 is laid on the soil surface inside the foundation portion 11, and concrete floor bundles 14 are erected on the soil portion 13 at predetermined intervals. An anchor bolt 15 is planted on the upper surface of each floor bundle 14.

Next, FIG. 4 shows a perspective view of a part of the foundation work. First, as shown in FIG. 4, when the installation position of the foundation 11 and the like is determined, the installation position of the floor bundle 14 is determined. A cylindrical form material 16 made of paper is installed corresponding to the installation position. At this time, the lower part of the form material 16 is floated above the soil surface by a reinforcing bar or the like so as to approximately match the height when the soil portion 13 is formed.
Further, inside the formwork material 16, a rebar connected to the soil part 13 is inserted together with the anchor bolt 15 as needed. In that state, concrete is placed on the soil surface and a base mat made of concrete is laid.

Then, as shown in FIG. 1, a standing form of the foundation part 11 is assembled, concrete is placed in the form, and concrete is also placed in the form material 16. Construction is performed such that the heights of the horizontal planes of the foundation portion 11 and the floor bundle 14 are kept constant.

Next, FIG. 3 shows the structure of a floor frame 17 for supporting the floor surface. A wooden base (not shown) is installed on the foundation 11, both ends are connected to the base, and each floor bundle 14 has an intermediate portion. Part is placed and a plurality of Daihiki 18 are installed in parallel, and a plurality of joists 19 are installed in parallel on the Daihiki 18 in a direction orthogonal to the Daihiki 18 and illustrated on the plurality of joists 19. Do not erection a floorboard.
When placing the Daihiki 18 on the floor bundle 14, the anchor bolt 15
Anchor bolt that is inserted through and protrudes from the upper surface of Daihiki 18
Pass the holding metal fitting 20 on the upper end of 15 and screw the nut 21 into the floor bundle.
Tighten 14 and Daihiki 18. The same applies when the base is placed on the foundation part 11.

In the floor structure constructed as above, since the concrete floor bundle 14 is erected integrally with the soil part 13, the floor bundle 14 is displaced or collapsed due to the vibration of the building such as an earthquake or a typhoon. The safety is ensured.

Further, the concrete floor bundle 14 has a large strength for supporting the floor surface, the installation interval can be widened and the number of installations can be reduced, and the economical efficiency and the workability are improved. In addition, since it is not necessary to use a conventional diagonal member such as a root clasp and the installation interval of the floor bundle 14 can be widened, the floor space is wide and the maintainability is improved.

Further, since the floor bundle 14 is made of concrete, it is not necessary to take measures against whiteness and the like, and it is possible to eliminate the need for after-maintenance after construction and reduce maintenance costs.

Further, since the concrete floor bundle 14 can be integrally installed during foundation work and has a constant height (horizontal surface etc.), it is easy to manufacture parts such as pre-cut parts and prefabricated parts that are machined with high precision. Can be installed in the building, shortening the construction period, improving the structural safety and quality accuracy of the entire building, and reducing the construction cost.

Also, the floor bundle 14 and the Daihiki 18 are anchor bolts.
By tightening the binding parts using 15 etc., it is possible to prevent common loosening of the floor (generally, the sound made when the floor is squeaked) with the wooden floor bundle.

The floor bundle 14 is not limited to the cylindrical shape as in the above embodiment, but may be provided in a polygonal shape.

Further, the construction method is not limited to the above embodiment,
The foundation part 11 and the floor bundle 14 may be formed first, and then the soil part 13 may be formed.

[0023]

According to the present invention, by using a concrete floor bundle, concrete is placed on the floor bundle at the same time as the foundation portion and the like during foundation work, and the floor bundle is erected integrally with the soil portion. As a result, it is possible to secure safety against earthquakes and vibrations, and ensure quality accuracy. Further, the strength of the floor bundle is high, the number of floor bundles to be installed can be reduced to a necessary minimum, and the economical efficiency and the workability can be improved, and the underfloor can be widened to improve the maintainability. Furthermore, it is possible to prevent harm such as whiteness without applying insect repellent treatment to the floor bundle.
