An independent foundation 120 is constructed between the outer cloth foundation 100 and the inner cloth foundation 110, and a base 122 is attached on the independent foundation 120.

A floor panel is laid on the foundation thus constructed, and a semi-base (not shown) is attached to the outer end of the floor panel to construct the floor portion of the first floor.

[0006]

[Problems to be solved by the device]

 Here, the independent foundation 120 supports the central portion in the longitudinal direction of the floor panel, but when the ground is soft, it is difficult to construct this independent foundation. In other words, in the soft ground, it took a lot of time and labor to lay the split stones and pile the piles before constructing the foundation. Moreover, since the independent foundation is scattered instead of being continuous like the cloth foundation, the basic geotechnical work was troublesome.

The present invention has been made in view of the above conventional problems, and an object thereof is to provide a floor structure of a building in which the strength of the floor can be maintained even if the independent foundation is omitted in the soft ground. It is in.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the invention according to claim 1 is a floor structure of a building constructed on soft ground, in which a foundation is constructed by a cloth foundation and the floor panel is supported by the cloth foundation, and a floor load is applied. It is characterized by having a thickness capable of obtaining a strength to withstand.

According to the second aspect of the invention, in a floor structure of a building constructed on soft ground, a foundation is constructed by piles driven into the ground and a cloth foundation supported by the piles, and the floor panel is The feature is that it is supported by a cloth foundation and has a thickness that enables it to withstand the floor load.

Furthermore, the invention according to claim 3 is the device according to claim 1 or 2, wherein the floor panel includes a thin floor panel and a thick floor panel, and the thin floor panel and the thick floor panel are joined together. In the section, an opening for a duct or a storage space is formed on the exposed side surface of the thick floor panel.

[0011]

[Action]

 In the device of the first aspect of the present invention having the above-mentioned structure, since the floor panel has a thickness capable of withstanding the floor load, the interval between the foundations around which the floor panel is suspended can be widened and the independent foundation can be omitted.

According to the second aspect of the present invention, a pile that supports the cloth foundation is driven into the ground, and the pile supports the cloth foundation. Here, since this ground is soft, in order to construct an independent foundation other than the cloth foundation, a pile that supports this independent foundation must be driven in. However, according to the invention of claim 2, this independent foundation is used. Is omitted and the foundation is constructed only by the cloth foundation.

Since the floor panel supported by the foundation thus constructed has a thickness that can withstand the strength of the floor load, even if the central portion is not supported by the independent foundation, only the end portion is supported. A strong floor can be obtained simply by supporting it with a cloth foundation.

Further, in the invention of claim 3, when a thin floor panel and a thick floor panel are used together to construct a floor, a duct or a housing is provided at an exposed side surface of the thick floor panel at a joint portion between these panels. The space opening can be formed to effectively utilize the space under the thick floor panel.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic perspective view showing a foundation constructed on soft ground for applying the floor structure of the building of the present invention. In the figure, a pile (not shown) is driven into a corner or the like of the foundation, and the outer cloth foundation 100 and the inner cloth foundation 110 are supported on the pile, and only the outer cloth foundation 100 and the inner cloth foundation 110 are used. It is designed to support the floor load sufficiently. The construction of the outer cloth foundation 100, the inner cloth foundation 110, etc. is the same as that of the conventional example shown in FIG.

A thick floor panel 10 and a thin floor panel 20 are laid on such a foundation. FIG. 2 is a plan view showing a state in which the thick floor panel 10 and the thin floor panel 20 are laid. In the figure, the thick floor panel 10 has a large distance between the outer cloth foundation 100 and the inner cloth foundation 110, and according to the prior art, it is laid at a position where the central portion should be supported by the independent foundation. Also, according to the conventional technique, the thin floor panel 20 is laid at a position where the support by the independent foundation is not required as in the case where the span between the cloth foundations is short.

Here, the thin floor panel 20 has a thickness of about 90 mm and has been conventionally used as a floor panel for the first floor. The thickness of about 90 mm is such that both ends in the longitudinal direction are supported by the outer cloth foundation 100 or the inner cloth foundation 110, and the central portion is conventionally supported by the independent foundation (see FIG. 5), so that the floor has sufficient strength. It was the obtained thickness.

Further, the thick floor panel 10 has a thickness of about 180 mm, and is a floor panel for the second floor that has been subjected to the necessary treatment as the floor panel for the first floor, such as attaching an anti-termite sheet. is there. This thickness of about 180 mm is a thickness at which sufficient strength as a floor can be obtained even if only the both longitudinal ends are supported by the outer cloth foundation 100 or the inner cloth foundation 110. This is also clear from the fact that the floor panel for the second floor has conventionally been able to obtain sufficient strength even if only the both ends in the longitudinal direction are supported and the center portion is not supported.

As described above, in this embodiment, the thick floor panel 10 having twice the thickness of the conventional floor panel for the first floor is used. Since the thick floor panel 10 has sufficient strength, only the both ends thereof are used. Sufficient strength as a floor can be obtained only by supporting the outer cloth foundation 100 or the inner cloth foundation 110. Therefore, the independent foundation can be omitted and the period of basic land work can be shortened. Moreover, since the floor panel is thicker than before, it has the effect of reducing floor space.

Next, FIGS. 3 and 4 show vertical cross sections of the joint portion when the thick floor panel 10 and the thin floor panel 20 are joined and laid on the inner cloth foundation 110 via the pedestal 30. In FIG. 3, the half-split material 32 is attached below the core material 22 of the thin floor panel 20 so that the surfaces of the thick floor panel 10 and the thin floor panel 20 are flush with each other.

In FIG. 4, as shown in FIG. 1A, the thick floor panel 10 and the thin floor panel 20 are laid so as to form a step difference 40. Further, on the side of the step 40, the core material 12 of the thick floor panel 10 is provided with an opening 14 as shown in FIG. Therefore, by using a duct panel having a duct formed inside the panel as the thick floor panel 10, the opening 14 can be used as an outlet for cold / hot air sent from the air conditioner or an inlet for ventilation. it can. Alternatively, a small item can be inserted into the panel through the opening 14.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the invention. For example, in the present embodiment, the conventional floor panel for the second floor is used as the thick floor panel 10, but the floor panel is not limited to this and may be a newly manufactured one.

[Effect of device]

 As described above, in the device according to the first aspect, the floor panel has a thickness capable of withstanding the floor load, so that the space between the foundations around which the floor panel is suspended can be widened and the independent foundation can be omitted. There is an effect.

In addition, in the device according to the second aspect, since the floor panel is supported only by the cloth foundation, the independent foundation can be omitted, and the period of basic ground work can be shortened. However, since the floor panel is thicker than the conventional floor panel, there is an effect that the floor is reduced.

Further, in the invention of claim 3, when a thin floor panel and a thick floor panel are used together, an opening of a duct or a storage space is formed on an exposed side surface of the thick floor panel at a joint portion of both panels. It can be formed to effectively utilize the space under the thick floor panel.
