「産業上の利用分野」
本発明は構造物の躯体構築に用いて好適な柱と梁の接合
工法およびその構造に関する。DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a column-to-beam joining method suitable for use in constructing the frame of a structure and its structure.
「従来の技術およびその課題」
一般に構造物の躯体を構築する際、鉄筋がご等によって
柱、梁を構築するとともに、これらにコンクリートを打
設することによって行っている。"Prior Art and its Problems" Generally, when constructing the frame of a structure, columns and beams are constructed using reinforcing bars, etc., and concrete is poured into these.
しかしながら、型枠工、配筋工等の熟練工の不足が深刻
な今日の建築現場の労務事情からは、これら熟練を要す
る作業を極力排除する必要がある。However, given the current labor situation at construction sites where there is a serious shortage of skilled workers such as formwork workers and reinforcement workers, it is necessary to eliminate these tasks that require skill as much as possible.
そして、今日までに、一部にプレキャストコンクリート
部分を有する柱（以下、半ＰＣ柱という）および、一部
にプレキャストコンクリート部分を有する粱（以下、半
ＰＣ粱という）を用いた、第１２図ないし第１４図に示
すような構造および工法が提供されている。To date, we have used columns with a precast concrete part (hereinafter referred to as "half-PC columns") and columns with a part of precast concrete parts (hereinafter referred to as "half-PC columns") as shown in Figure 12. A structure and construction method as shown in FIG. 14 is provided.
第１２図に示す柱と梁の接合構造では、粱の構築位置に

８が複数本突設されている。そして、この粱３の梁筋５
を、前記柱１の柱筋７内へ配置した状態でコンクリート
を打設することによって柱１と梁３の接合を行つ。In the column-to-beam joint structure shown in FIG. 12, a beam 3 is placed and fixed on the top surface of a column 1 formed at the construction position of the bamboo shoots. This girder 3 is constructed from a half-PC beam, and has beam reinforcements 5 protruding from both ends in the longitudinal direction, and the beam reinforcements 5
The tip is bent upward. Furthermore, a plurality of stirrups 8 having a U-shaped appearance and serving as shear reinforcing bars for the beam 3 are protruded from the upper surface of the beam 3 . And this 粱 3's beam 5
The column 1 and the beam 3 are joined by placing concrete in the column reinforcement 7 of the column 1.
しかしながら、このような構造では、柱１と粱３の接合
部における柱筋７と梁筋５の納まりが良くないとともに
、定着長さが取れないといった問題があった。However, in such a structure, there were problems in that the column reinforcements 7 and beam reinforcements 5 did not fit together well at the joints between the columns 1 and the casings 3, and the fixation length could not be secured.
第１３図に示す接合構造は、前記第１２図に示した接合
構造とほぼ同様であるが、粱３の両端部にＵ字形断面部
３ａを形成した点で異なっている。The joining structure shown in FIG. 13 is almost the same as the joining structure shown in FIG. 12, but differs in that a U-shaped cross section 3a is formed at both ends of the rice bran 3.
そして、柱１上に粱３を載置した際に、それぞれの粱３
のＵ字形断面部３ａに延在する新たな梁筋９を配置し、
この状態でコンクリートを打設することによって接合作
業を行う。Then, when placing the rice 3 on the pillar 1, each rice 3
A new beam reinforcement 9 extending to the U-shaped cross section 3a is arranged,
The joining work is performed by pouring concrete in this state.
しかしながら、この場合は、梁３を所定位置に支持する
際に、粱３の両端部にそれぞれ１本ずつ合計２本の支持

Ａ−原因となっていた。また、Ｕ字形断面部が梁１本に
つき２箇所必要となるため、梁の成形作業が繁雑となる
といった問題もあった。However, in this case, when supporting the beam 3 in a predetermined position, a total of two supports (shown paths) are required, one at each end of the beam 3, so it is necessary to increase the number of temporary materials. A- It was the cause. Furthermore, since two U-shaped cross sections are required for each beam, there is a problem in that the beam forming operation becomes complicated.
第１４図に示す接合構造は、半ＰＣ梁の」１下方向に貫
通する貫通孔（図示路）を形成して、当該貫通孔に柱筋
を挿通ずる構造である。この構造では、梁をＸ７両方向
に構成させるのが難しいといった問題があった。The joining structure shown in FIG. 14 is a structure in which a through-hole (path shown in the figure) is formed that penetrates downward through the half-PC beam, and a column reinforcement is inserted into the through-hole. This structure had a problem in that it was difficult to configure the beams in both the X7 directions.
