本発明は正多角形型山留における中央集中型切梁の施工
法に係るものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method of constructing a centralized strut in a regular polygonal sill.
（従来の技術）
従来正多角形型山留における中央集中型切梁の施工に際
しては、相対する山留壁間に切梁を中央部において集中
するように放射状に架設していた。(Prior Art) Conventionally, when constructing centralized struts in regular polygonal retaining walls, the struts were constructed radially between opposing retaining walls so as to be concentrated in the center.

打材等の複雑な補助部材を必要とし、また切梁が長尺の
部材となるため座屈の惧れがある。(Problem B to be solved by the invention) In the conventional construction method, the struts are concentrated in the center, so the struts overlap in the center, and complicated support such as uneven flint is required at the raised end. It requires additional members, and since the struts are long members, there is a risk of buckling.
本発明は前記従来技術の有する問題点に鑑みて提案され
たもので、その目的とする処は、施工が簡単で、構造上
合理的な山留切梁工法を提供する点にある。The present invention has been proposed in view of the problems of the prior art described above, and its purpose is to provide a mountain retaining beam construction method that is easy to construct and is structurally reasonable.

するものである。(Means for Solving the Problems) In order to achieve the above-mentioned object, the mountain retaining beam construction method according to the present invention constructs a core frame made of reinforced concrete in the center part of the centralized strut in a regular polygonal type mountain retaining. Then, peripheral struts are installed between the core frame and the sill, and the same structural surface is formed by each of the struts and the core frame.

込んで基礎躯体の一部とするものである。(Function) According to the present invention, a core frame made of reinforced concrete is constructed in advance at the central strait installation position of a regular polygonal centralized strait, and then a core frame made of reinforced concrete is constructed between the core frame and the retaining wall. The peripheral struts are erected so as to form the same structural surface as the core body, and after the excavation is completed, the core body is embedded without disassembly and becomes part of the foundation body.
（実施例） 以下本発明を図示の実施例について説明する。(Example) The present invention will be described below with reference to the illustrated embodiments.
平面正多角形状の基礎部周辺に沿って親杭（１）を貫入

周辺切梁（４）を架設し、同各切梁（４）と前記コア躯
体（３）とにより同一構面を形成する。The parent pile (1) is penetrated along the periphery of the foundation, which has a regular polygonal shape in plan, and the core frame support shelf pile (2) is driven in the center (see Fig. 1), then as shown in Fig. 2. The roots were cut down, and a reinforced concrete core frame (
3), erect the peripheral struts (4) between the core frame (3) and the main pile (1), and construct the same structure with each of the core frames (4) and the core frame (3). form a surface.

体（６）の一部とするものである。Next, excavation is carried out to a predetermined depth (see Figure 3), and then the foundation structure (6) is constructed. (See Figure 4) At this time, since the core body (3) is made of reinforced concrete, it is embedded in the foundation body (6) without being dismantled, and becomes a part of the same body (6) as it is.

ルな形状とし、応力設計を簡明にしうるちのである。(Effects of the Invention) According to the present invention, as described above, a reinforced concrete core frame is constructed in advance at the central strait installation position of a centralized strait in a regular polygonal pile, and then the core frame is constructed. By constructing the peripheral struts between the base and the crest so as to form the same structural surface as the core frame, the struts can be made into a simple shape and the stress design can be simplified.
また本発明によれば切梁の中央部における重なりがなく
なるので、座屈長が小さい架構となり、構造的に有利で
あり、また前記各切梁の腹起し端部に、従来の如き段違
い火打材の如き特殊な取付部材が不要となる。In addition, according to the present invention, since there is no overlap in the central part of the struts, the buckling length becomes small, which is structurally advantageous. Special mounting members such as wood are not required.

そのまま埋込み、基礎躯体の一部とすることができ、施
工が簡略化される。Furthermore, according to the present invention, since the central core body is made of reinforced concrete, it can be embedded as is and become a part of the foundation body without being dismantled, which simplifies construction.
