埋設された鉄筋コンクリート柱が構築される。(Function) According to the present invention, as described above, a lightweight, thin-walled precast member is constructed in which the outer periphery of a column is divided into a single concrete body, and the tie bars are partially protruded from the single concrete body. By surrounding the column main reinforcing bars arranged in advance on site with the thin precast members, making the precast members also serve as weir plates, and pouring concrete between the members, the cast concrete and the above-mentioned A reinforced concrete column is constructed in which the thin precast member is integrated and the column main reinforcement and column reinforcement are buried.
（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.

クリート柱を構築する。At the site, as shown in Fig. 1, the main column reinforcements (4) were arranged, and a pair of groove-shaped thin precast members were attached from both sides of the main column reinforcements (4), and the joint play was performed (5). The two parts are combined by . (See Figure 2) Next, after reinforcing against lateral pressure during concrete pouring as necessary, concrete is poured into the space surrounded by the two thin plate members to construct a reinforced concrete column.

Construct a precast member, surround the reinforcing bars arranged in advance with the member, make the member serve as both a structure and a formwork, pour concrete between the members, and install the main column reinforcement and tie reinforcement. By constructing buried reinforced concrete columns, it is possible to save labor in formwork work, reduce the weight of precast members, eliminate the trouble of arranging tie bars, and improve workability.
