Description
【０００１】[0001]
本考案は、建築物の基礎に使用する基礎杭に係り、特に住宅等の基礎として使 用するのに好適な基礎杭に関する。 The present invention relates to a foundation pile used for a foundation of a building, and particularly to a foundation pile suitable for being used as a foundation of a house or the like.
【０００２】[0002]
従来この種の基礎杭として、特開平7-54355 号公報に記載された小規模建築物 用基礎が提案されている。この基礎は、現地盤の土とスラリー状の硬化材を混練 して柱状固決体を構成し、この柱状固決体の内部に鋼管を挿入し、柱状固決体の 上部にほぼ同一の大きさの鉄筋コンクリート版を設け、これらの鉄筋コンクリー ト版と柱状固決体とを一体化させて使用するものである。 Conventionally, as this type of foundation pile, a small-scale building foundation described in Japanese Patent Application Laid-Open No. 7-54355 has been proposed. This foundation is made by kneading the soil of the site and the hardening material in the form of slurry to form a columnar solidified body. A steel pipe is inserted into the columnar solidified body, and a substantially same size is placed on the upper part of the columnar solidified body. The reinforced concrete slabs are provided, and these reinforced concrete slabs and the columnar fixed bodies are integrated and used.
【０００３】 また、一般住宅の基礎は、図５に示す如く、基礎を構築する地面に割りぐり石 １０を敷設し、この割りぐり石１０の上にコンクリート製の基礎Ｐを構築する手 段が多く使用されている。As shown in FIG. 5, a foundation for a general house is constructed by laying a shard 10 on the ground on which the foundation is constructed, and constructing a concrete foundation P on the shard 10. Many are used.
【０００４】[0004]
ところが、従来の基礎は、現地盤の土とスラリー状の硬化材を混練して柱状固 決体を構成する作業や、この柱状固決体の内部に鋼管を挿入する作業等に多くの 労力と手間を要するものである。したがって、従来の一般住宅で使用される基礎 に代えて、柱状固決体の内部に鋼管を挿入するような手段の基礎を使用する場合 工事費が極めて高くなると共に、工期が延長されることにもなるから、柱状固決 体の内部に鋼管を挿入するような基礎を一般住宅で実用化するには、経費、工期 と共に現実的ではなかった。 However, the conventional foundation requires a great deal of labor for kneading the soil on the site and the hardening material in the form of slurry to form a columnar fixed body, and for inserting a steel pipe inside the columnar fixed body. It takes time and effort. Therefore, in the case where the foundation used for inserting steel pipes inside the columnar fixed body is used instead of the conventional foundation used for ordinary houses, the construction cost will be extremely high and the construction period will be extended. Therefore, it was not feasible, along with cost and construction period, to put a foundation such as inserting steel pipes inside a columnar fixed body into practical use in ordinary houses.
【０００５】 しかしながら、近年の住宅事情から、軟弱な地盤での構築をやむなくされてい る状況で、安全性の高い基礎が強く求められている。しかも、このような不利な 条件に一般住宅を建築する場合は、高い経費を捻出するのが困難な場合が多いこ とから、できるだけ安価な費用で強度に勝れ、工期の延長も少ない基礎杭の提供 が求められている。[0005] However, in recent years, due to housing conditions, construction on soft ground has been unavoidable, and a foundation with high security has been strongly demanded. In addition, when constructing a general house under such disadvantageous conditions, it is often difficult to generate high costs, so foundation piles that can excel in strength at the lowest possible cost and have a short construction period are required.

本考案は上述の如く構成したことにより、当初の目的を達成した。 The present invention has achieved the original object by being configured as described above.
【００２０】 すなわち、宅地用地盤に基礎を構築する基礎杭において、地盤に垂直に埋設す る鋼管１と地盤に水平に載置する支持枠体２とを設け、地盤に埋設された鋼管１ の側面に配設した支持枠体２と鋼管１とを一体に溶着して基礎杭を形成し、この 基礎杭の上に住宅用の基礎を構築するようにしたことで、地盤に垂直に埋設する 鋼管１と地盤に水平に載置する支持枠体２とによって住宅を強固に支持すること ができる。したがって、軟弱な地盤に構築しなければならない場合や家庭用のエ レベーターを装備した重量のかさむ住宅でも、強固に支持することが可能で、耐 震にも対応することができる。That is, in a foundation pile for building a foundation on residential land, a steel pipe 1 buried vertically in the ground and a support frame 2 mounted horizontally on the ground are provided, and the steel pipe 1 buried in the ground is provided. The supporting frame 2 and the steel pipe 1 disposed on the side are welded together to form a foundation pile, and a foundation for a house is constructed on the foundation pile, so that the foundation pile is buried vertically in the ground. The house can be firmly supported by the steel pipe 1 and the support frame 2 placed horizontally on the ground. Therefore, it can be firmly supported even when it is necessary to construct it on soft ground or in a heavy house equipped with a home elevator, and can respond to earthquakes.
【００２１】 また、鉄筋２Ａを組み合わせて略篭状に形成した平行なな一対の支持枠体２を 連結鉄筋３で連結して支持枠体２を形成したことで、現場でも地盤の形状に合わ せて支持枠体２の形状を自由に形成することができる。この結果、地盤の条件に 最も適合した基礎杭を提供することができる。しかも、鋼管１と鉄筋２Ａで基礎 杭を形成するので、柱状固決体の内部に鋼管を挿入する従来の基礎に比べて経費 が安くなり、工期も短くて済むから一般住宅の基礎として十分に実用化できる。In addition, the pair of parallel support frames 2 formed in a substantially cage shape by combining the reinforcing bars 2A are connected by the connecting reinforcing bars 3 to form the support frame 2, so that the support frames 2 are adapted to the shape of the ground even at the site. Thus, the shape of the support frame 2 can be freely formed. As a result, it is possible to provide a foundation pile most suited to the ground conditions. Moreover, since the foundation pile is formed by the steel pipe 1 and the reinforcing bar 2A, the cost is lower than that of a conventional foundation in which a steel pipe is inserted into a columnar fixed body, and the construction period is short. Can be put to practical use.
【００２２】 更に、平行な一対のアングル材２Ｂを連結鉄筋３で連結して支持枠体２を形成 したことで、極めて強固な基礎杭を形成することが可能である。Further, by forming the support frame 2 by connecting the pair of parallel angle members 2 B with the connecting reinforcing bar 3, it is possible to form an extremely strong foundation pile.
