この発明はフラツトスラブ構造等スパンの大き
い建築物の最下階の地下室の建築物の基礎構築法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of constructing a foundation for a basement on the lowest floor of a building with a large span such as a flat slab structure.
一般に建築物の地下室の最下階では湧水、雨水
の止水のためおよび結露対策のため1.50〜2.00ｍ
の間隔をもつてかつ地中梁を配した二重スラブ構
造が採用されている。したがつてそれだけ地下の
根切りが深くなり、施工費が多くなる。 In general, the lowest floor of a building's basement is 1.50 to 2.0m to stop spring water and rainwater and to prevent condensation.
A double slab structure with underground beams is adopted, with a spacing of . Therefore, the underground root cutting becomes deeper and the construction cost increases.

する空間がなく、これに対処すべき技術の開発が
要望された。 Therefore, we considered applying a flat slab structure that uses unbonded PC steel wire, which can have a thin slab thickness, but it requires measures against moisture, and because it is underground, there is no space for tension fixing of the unbonded PC steel wire. There was a demand for the development of technology to deal with this.

３が基礎スラブ１の上面より低く形成してある。 First, a foundation slab 1 of a reinforced concrete structure is constructed in contact with the cut ground A. The foundation slab 1 is made thicker by bulging downward at the bottom of the pillar 6, while the other parts are made thinner, and the unbonded PC is placed approximately on the tension side of the slab.
A steel wire 7 is buried in the concrete of the foundation slab 1. An earth retaining wall 2 is constructed around the foundation slab by an underground continuous wall or the like. A drainage channel 3 having a width of approximately 1 m in depth is formed in the foundation slab 1 at an appropriate location, for example, between the earth retaining wall 2 or in the middle of the foundation slab, and is lower than the upper surface of the foundation slab 1.

The floor is formed by
Therefore, a gap is formed between the top surface of the foundation slab and the support member 4.

る。 This invention has the above-mentioned structure. First, the lower part of the column is thick, the other parts are thin, and a foundation slab of reinforced concrete structure is constructed in contact with the soil on the ground.
By burying the unbonded PC steel wire inside the foundation slab so that it is located on the tension side, a foundation slab with a smaller overall thickness is created, so the basement floor is smaller than the conventional double slab structure. A low foundation with a small amount of root cutting can be quickly constructed. At this time, the unbonded PC steel wire is tension-fixed in the drainage channel that is formed below the top surface of the foundation slab, so it is easy to work even underground. Furthermore, floor finishing can be done sequentially after the construction of the frame, and repairs are easy. Additionally, a drainage channel connected to the foundation slab provides drainage and moisture control.
