Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for constructing floors in buildings such as wooden buildings, and more particularly to a method for forming concrete floor plates.

Conventional standing flow methodIn recent years, underfloor heating, which heats the floor from the floor by installing hot water pipes under the floor, has come into use.

In such a case, the floor structure consists of pouring concrete over the entire surface of the floor to form a concrete floor plate, and placing heating components such as hot water pipes and electric heaters on or within the floor plate. There is.

Conventionally, concrete slabs are constructed by excavating the outer periphery and main part of a building, pouring concrete for the base of the foundation here, and after hardening, a temporary frame is placed on top of this and concrete is poured to form the rising part of the foundation. After forming and removing the temporary frame, backfilling, embanking the area surrounded by the rising part and compacting the ground.
It was formed by pouring concrete over the entire surface.

However, with this construction method, the embankment and soil compaction processes were troublesome, leading to an increase in construction costs. In particular, when renovating an existing wooden building to form a concrete floor, it is necessary to bring the soil for the embankment into the house, which may cause the house to become dirty, and preparations must be made to prevent this staining. There were problems such as being troublesome.

Furthermore, although the load of the building itself can be supported by the base of the foundation,
The load of heavy objects placed on the floor would be applied directly to the concrete bed, and if there were weak areas in the embankment, there was a risk of immobility and settlement. As a countermeasure to this problem, a concrete floor plate is connected to the rising part of the foundation, and the weight of the floor is placed on the bottom plate of the foundation. However, with such a structure, there is a problem in that heat escapes from the concrete floor to the outside through the foundation upright portion, resulting in a reduction in heat insulation. This problem is particularly serious in floor heating structures.

The present invention aims to provide a method of constructing a floor that can easily form a concrete floor slab with excellent strength and is also suitable as a floor for underfloor heating because it is easy to create an insulating structure. It is.

The floor construction method of the present invention involves pouring concrete for the bottom plate of the foundation that supports the load of the building around the outer periphery and main part, forming a rising part on the bottom plate, and then forming a concrete base surrounded by the rising part. The method is characterized in that a plurality of pipe bodies are placed side by side in a space separated from each other, and then concrete is cast around the pipe bodies to form a concrete floor plate.

Figure 1 is an explanatory diagram (cross-sectional view) showing an embodiment of the present invention.

The outer periphery and main part of the building are pre-excavated and concrete is poured to form the base plate 11 of the foundation. Next, a temporary frame (not shown) is set and concrete is poured to form the rising portion 13. 15 indicates reinforcing bars.

After the concrete in the rising part 13 hardens, the temporary frame is removed and the pre-excavated area surrounding the rising part 13 is backfilled with soil.

Next, the cylindrical tubes 21 are placed side by side over the entire surface of the area surrounded by the rising portion, with a slight distance between them. At this time, small stands (not shown) are placed here and there on the ground surface OL, and the pipe body 21
By making it slightly floating above the ground surface GL, it is possible to spread the concrete to the lower part of the pipe body 21 as well. In addition, in the conventional construction method, embankment was placed in this area, but this method does not require it.

Next, a heat insulating material 23 is provided inside the rising portion 15, and the pipe body 2
Concrete is poured around 1 and concrete floor plate 2 is created.
form 5. After that, a desired floor can be formed on this floor board 25. Fig. 1 shows a case where floor heating is performed, in which a heat insulating material 31 is laid, a hot water pipe 33 for floor heating is laid, a heat storage material 35 is arranged around this, and a floor finishing material 37 such as tatami mats is laid. It is laid down. Note that for convenience of illustration, joists and the like are omitted. Concrete can be placed by simply pouring the concrete into the underfloor space using pipes, so workability is extremely good and construction costs can be reduced. Particularly when renovating a part of an existing home to form a concrete floor, all you have to do is remove the floorboard, line up the pipes in the space under the floor, and then pour concrete through the pipe and place it. is good. In addition, since the pipe bodies 21 are used to construct the floor structure using a small amount of concrete as described above, they are arranged side by side on almost the entire surface of the underfloor space, and the intervals are narrowed to the extent that strength allows, and pipe bodies with a large diameter are used. It will be done. Note that the tube body is not limited to a cylindrical shape, and may have a rectangular cross section, for example.

The pipe body 21 is used to form a floor board using a small amount of concrete, and it is sufficient that the pipe body 21 maintains its shape until the concrete hardens, and is not required to have sufficient strength as a structural member. Therefore, if cost etc. are taken into consideration, a paper tube is sufficient.

In addition, as shown in FIG.
By burying 7, the bonding force of the concrete is increased, the strength is increased, and the thickness of the concrete in this area can be reduced.

As shown in FIG. 3, when the concrete floor plate 25 is partially viewed, it has an engineering type structure. Concrete floorboard 25
The whole can be seen as a continuum of this single-shaped structure, and great strength can be obtained.

Further, the lower part of the concrete floor plate 25 is not filled with earth, and is a solid ground surface. Therefore, the concrete floor plate 25 is strong by itself,
Furthermore, there is no risk of immobility or subsidence. Therefore, the floor constructed by the method of the present invention is suitable not only for general residences and stores, but also for factories where heavy loads are applied, gymnasiums, and the like. In addition, since there is no risk of immobility and settlement, there is no need to fix the concrete slab 25 to the rising part 13 of the foundation.
As shown in the figure, the heat insulating material 23 is provided over the entire height, making it possible to completely insulate the floor from the outdoors. Therefore, heat is prevented from escaping outdoors and moisture is prevented from entering from the outside in the path between the concrete floor plate 25 and the rising portion 13 of the foundation, and is particularly suitable as a floor structure for floor heating.

According to the present invention, pipe bodies are placed side by side in the area surrounded by the rising part of the foundation, and concrete is poured around this, thereby requiring complicated work such as embankment and soil compaction. It has excellent workability and can form a strong concrete floor with a small amount of concrete. Since this tube body does not require strength, a paper tube or the like can be used, and it will not lead to an increase in cost.

In addition, unlike conventional construction methods, the problem of immobility and settlement can be solved, so an insulating structure can be used, and excellent heat insulation effects can be obtained.
