して新地盤OL2を得るようにしている。Conventional solid foundations lay on the front of the slab. After excavating the ground, placing slabs and reinforcing, concrete was poured twice for the slab and foundation beams. However, with this construction method, the ground is excavated over the entire surface of the slab, which creates problems in disposing of the remaining soil.
It has the disadvantage of being expensive to discharge. Therefore, the method shown in Figure 1 has been considered as a construction method that solves this problem of disposal of residual soil. In the construction method shown in Fig. 1, a trench (2) is excavated only in the part where the foundation beam 11) passes;
) and the groove (2), then concrete is placed on the slab (3), and then the foundation beam (1) and the partition foundation (4) are placed. )
By pouring concrete in the area and excavating the trench (2);
The discharged soil is spread over the old ground GLI around the outer periphery of the foundation to obtain new ground OL2.

うことが必要となる等の欠点がある。According to the method shown in Figure 1, only the area where the foundation beam (1) passes is excavated, and all the soil obtained through this excavation is distributed around the outside, which has the advantage of solving the problem of disposal of remaining soil. However, even with this construction method, concrete is poured separately into the slab (3), foundation beam (1), and partition foundation (4), so it is necessary to pour concrete on two sides. Formwork had to be built on the inside of the beam (11) and the partition foundation (4), which required a large amount of formwork, and if it rained during the construction period,
Rainwater accumulates inside the foundation beam +11, so there are drawbacks such as the need to drain water.
本発明は、上記従来の欠点を解消したべた基礎とその施

うことを特徴するものである。The present invention provides a solid foundation and its construction method that eliminate the above-mentioned conventional drawbacks, and the solid foundation of the present invention has a hollow part formed inside and the upper surface of the solid foundation is made of carpet. The method of the present invention is characterized in that it has a flat shape that allows for direct construction of floor interior materials such as earwood and tatami mats, and furthermore, the construction method of the present invention involves forming a trench by excavating only the foot part to be embedded into the ground. Then, a steel pipe for forming a hollow part is placed along with reinforcement on the electric panel surrounded by this groove, and concrete is poured, and after that, floor interior materials such as carpet and tatami mats can be directly applied to the upper surface of the concrete. It is characterized by leveling to make it flat.
以下、本発明の構成をその施工順序に従って説明すると
、まず、第2図で示すように、必要な根入れ深さを確保
するため、スラブ外周の根入れ足部分に沿って、溝(1

て囲まれる電盤上に栗石(12)を敷く。The structure of the present invention will be explained below according to the construction order. First, as shown in Fig. 2, in order to secure the necessary penetration depth, a groove (1
1) is excavated, and a chestnut stone (12) is laid on this groove (11) and the electrical panel surrounded by the groove (11).
次いで、第3図の如く、スラブ外周部に沿って型枠(1

As such a steel pipe (15), a thin-walled steel pipe commonly called a winding pipe is used. Further, a moisture-proof sheet (16) is spread over the entire surface of the chestnut stone (12) on the surface plate.

Obtain L2.
本発明のべた基礎及びその施工方法は上記の通りである
から、掘削土量が少なく残土処理の問題がないという第
1図と同様の利点の他に次のような効果が得られる。Since the solid foundation and its construction method of the present invention are as described above, in addition to the same advantages as shown in Fig. 1, in which the amount of excavated soil is small and there is no problem of disposal of remaining soil, the following effects can be obtained.
■、コンクリートの打設は一回ですみ、工事期間が大幅
に短縮される。■Concrete pouring is only required once, significantly shortening the construction period.
■、スラブ上面がそのまま内装材を施工できるようにな
っているから、従来の如く基礎梁を突出させる必要がな
(、それ故、工事期間中に雨が降っても雨水が溜ること
がなく、水抜き処理が不要である。■Since interior materials can be constructed on the top surface of the slab, there is no need to protrude the foundation beams like in the past (therefore, even if it rains during the construction period, rainwater will not accumulate, No water removal process is required.
■、スラブ部分と基礎梁部分に分けて二面のコンクリ−
゛ト打設を行う必要がなく、型枠はスラブ外周部のみに
組めばよいから、必要な型枠面積は、約三分の−と大幅
に減少する。■ Concrete on two sides, divided into slab part and foundation beam part.
Since there is no need to perform concrete pouring and the formwork only needs to be assembled on the outer periphery of the slab, the required formwork area is significantly reduced by about a third.
■、前記の如くスラブ上面に直接床内装材等が施工でき
るから、束石や床組みが不要で、コストが大幅に減少す
る。(2) As mentioned above, floor interior materials, etc. can be applied directly to the top surface of the slab, so there is no need for stacking stones or floor assemblies, and costs are significantly reduced.
■、同じ(、スラブ上面に直接床材等が施工できるから
、床振動等が全(なくなる。■Same (because flooring materials can be installed directly on the top of the slab, floor vibrations, etc. are completely eliminated).
■、スラブ部分の肉厚が大きくなり、しかも中空のため
、保温性が高い。■The thickness of the slab part is large and it is hollow, so it has high heat retention.
■、内部は中空となっているから、コンクリート量は、
従来のべた基礎より僅かに増えるだけであり、しかも、
中空部があることにより、重量はさほど大きくならず、
この種べた基礎が施工される軟弱地盤に用いたとしても
何等不都合はない。■Since the interior is hollow, the amount of concrete is
It is only slightly more than the conventional solid foundation, and moreover,
Due to the hollow part, the weight is not very large,
There is no problem in using this type of solid foundation on soft ground.
■、スラブの裏面に防湿シートを敷けば、床下の湿気を
完全に排除することができる。■By laying a moisture-proof sheet on the back of the slab, you can completely eliminate moisture under the floor.
