本発明はプレキヤスト材と現場打ちコンクリー
トを併用したコンクリート建築物の構築方法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION (Technical field to which the invention pertains) The present invention relates to a method of constructing a concrete building using a combination of precast material and cast-in-place concrete.
（発明の課題とその特徴点）
梁、床等のプレキヤスト材（プレキヤストコン

キヤスト材を用いることも既に知られている。(Problems to be solved by the invention and its features) Constructing concrete buildings using precast materials (an abbreviation for precast concrete members, including those in which prestress is introduced) such as beams and floors has not been practiced for a long time. It is already known to use precast material for columns.

い。 Using precast material for columns has many advantages, such as reducing the cross section of the column and shortening the construction period, but if the entire column is made of precast material, it is still quite heavy, making transportation and construction difficult. However, it is difficult to construct rigid joints at the nodes of the frame.

請求の範囲に記載したとおりである。 The present invention aims to provide a method for constructing a concrete building that does not have the above-mentioned difficulties while taking advantage of the advantages of using precast materials for columns, and its structural features are patented. As stated in the claims.

層建築物でも容易に構築可能である。 That is, the present invention provides for the core of the column, the beam, and the floorboard.
Furthermore, in some cases, precast materials are used for shear walls, and by skillfully combining these precast materials with cast-in-place concrete, it is possible to efficiently and economically construct multi-story concrete buildings with reliable strength. According to the present invention, even high-rise buildings of about 10 or more floors can be easily constructed.

This is a reinforcing bar that is embedded in the concrete of the column 2 on the floor and extends to the middle of the precast core column 1 on the nth floor.

+1) Reinforcement is also placed at the joints between the precast core columns 1 and 1' on the floor and on the outside of the precast core columns 1 on the nth floor, and the formwork 7 for forming the columns on the nth floor is set. This is the stage where preparations are being made for pouring on-site concrete, and at this time, the lower ends of the reinforcing bars 3' extending to the intermediate positions between the nth and (n+1) floors are attached to the upper ends of the reinforcing bars 3 extending from the pillars on the (n-1) floor. Connect and extend the reinforcing bars (vertical bars) of the column upward.

層のコンクリート建築物を構築する。 When the cast-in-place concrete is placed in the reinforcement area shown in Figure 5, the construction of the nth floor is completed, and this is the same situation as in Figure 1 (the shaded area is the cast-in-place concrete). A concrete building of a predetermined level is constructed repeatedly.

のであることはいうまでもない。 In addition, n = 1, that is, the precast core on the first floor is fixed on the column foundation via the column base, and the above-mentioned construction is repeated from the first floor upwards, but the construction on the top floor is as described above. In construction (n+
1) It goes without saying that there is no connection process for the precast core columns on the floor.
