In this case, the PC beam erected between the columns is supported by the beam support,
The beam-to-column joints are joined, the required beam-to-column joints are provided with necessary reinforcing bars, and a connection form is formed. This is also supported by the shoring, and then the connection is made. Concrete is poured into the formwork, and when the required curing period elapses and the concrete has developed a certain strength, those preservation works and the formwork are dismantled and removed, and then the finishing work is started.
しかし、狭い空間での支保工の組立・解体が容易でな
く、未だ多くの手数及び時間を要し、コスト高を招いて
いる。また、人手不足の今日、早急な改善が望まれてい
る。However, it is not easy to assemble and disassemble the shoring work in a narrow space, and it still requires much trouble and time, resulting in high cost. In addition, with the shortage of labor, urgent improvement is desired.
本発明は、斯る問題点を解決しようとするものであ
る。The present invention seeks to solve such a problem.

ることを特徴とする。"Means for Solving the Problems" The present invention relates to a PC wall slab erected between pillars before the beam is constructed, and the PC wall slab is also used as a beam supporter, and the PC slab is installed later. It is characterized in that the beam is supported, then the beam-to-column connection is joined, and concrete is laid with the required reinforcement in the beam-to-column connection.
「作用」 如上の構成であるから、PC壁版は、梁支保工を無用に
し、梁支保工に要する資材、その組立・解体に係る手数
及び時間を不要にする。[Operation] Because of the above configuration, the PC wall slab eliminates the need for beam support, and eliminates the need for materials required for beam support, as well as the labor and time required for assembling and dismantling the beam.
「実施例」 第１図Ｉ〜IVは、施工の手順を示している。以下、順
を追って説明する。"Example" Figs. 1 to 4 show the procedure of construction. Hereinafter, description will be made in order.
Ｉ 柱鉄骨1,1を建方し、床コンクリートを打設して床
２を施工した後、該床上に墨出しを行う。I Pillar steel frames 1 and 1 are erected, floor concrete is cast and floor 2 is constructed, and then blacking is performed on the floor.
II 柱鉄骨1,1の周りに柱配筋3,3を施し、柱型枠4,4を
組立てて支保工（図示せず）にて支保する。II Column reinforcements 3,3 are provided around the column steel frames 1,1, and the column forms 4,4 are assembled and supported by shoring (not shown).
また、柱と柱との間の中間部分に数個のPC壁版5,5を
建込み、それぞれアングル6,6及び支持ボルト７……で
固定する（第２図、第３図参照）。In addition, several PC wall slabs 5, 5 are erected at an intermediate portion between the columns, and fixed with angles 6, 6, and support bolts 7, respectively (see FIGS. 2 and 3).
III 鉄骨鉄筋コンクリートのPC梁８を建入れ、上記PC

事に入る。Then, concrete 14 (see FIG. 2) is poured into the column formwork 4, 4 and the joint formwork 10, 10 and on the deck plate 12 or the omnia plate, respectively, and a necessary curing period is set. After a certain amount of strength has developed in the cast concrete 14 after the elapse, the temporary members such as the supports, column formwork 4, 4 and connection formwork 10, 10 are dismantled and removed as shown in FIG. Building frame pillars 15,1
5, Build girder 16, slab 17, etc. After that, finishing work starts.
