【考案の詳細な説明】
この考案は鉄骨鉄筋コンクリート造または柱鉄
骨鉄筋コンクリート造梁鉄骨造などの複合構造に
おける柱梁接合部、いわゆるパネルゾーンのせん
断補強筋構造に関するものである。[Detailed Description of the Invention] This invention relates to a shear reinforcement structure at a so-called panel zone, which is a column-beam joint in a composite structure such as a steel-reinforced concrete structure or a column-steel-reinforced concrete-beam steel structure.
建築物の骨組構造において、柱と梁とで囲まれ
たパネルゾーンは骨組の中でも最も応力が集中す

いては、このパネルゾーンについて、工事現場で
鉄筋をまいて補強するのが通常であるが、この施
工が極めて煩雑である。 In the framework structure of a building, the panel zone surrounded by columns and beams is the part of the framework where stress is most concentrated, and is structurally extremely important. In frameworks consisting of steel reinforced concrete columns and steel reinforced concrete beams or steel beams, this panel zone is usually reinforced by wrapping rebar around it at the construction site, but this construction is extremely cumbersome.
従来このような柱梁接合部の補強構造としては
例えば、第１図に示すようなものがある。しか
し、接合部では梁のウエブを貫通させて配筋する
ため施工上その形状は簡単な形に制限される。 An example of a conventional reinforcement structure for such a column-beam joint is shown in FIG. 1. However, since reinforcement is placed through the web of the beam at the joint, the shape of the joint is limited to a simple shape for construction purposes.
そのためＬ形をしたせん断補強筋を４本１組に
して、それぞれ重ね長さｌだけラツプし、この部
分を溶接したり、定着長さ分だけ確保したりして
いるのが、現状である。ところが、溶接は補強法
としては効果的だが施工が大変であり、一方定着
長さ分確保する方法は、施工はしやすいが、接合
部のはらみ出しに対して効果的でないという欠点
がある。 Therefore, at present, L-shaped shear reinforcing bars are made into a set of four, each lapped by an overlap length l, and this part is welded or secured by the anchoring length. However, although welding is effective as a reinforcing method, it is difficult to construct, while the method of securing the anchorage length is easy to construct, but has the disadvantage that it is not effective against protruding joints.
この考案の柱梁接合部の補強構造は、上述のよ
うな従来技術における欠点を解消するために考案
されたものである。 The reinforcing structure of the column-beam joint of this invention was devised in order to eliminate the drawbacks of the prior art as described above.
すなわち、柱の各隅角部において柱主筋を取り

填性の改善等を図つた。 In other words, we considered a device that combines a main reinforcement restraint ring surrounding the main column reinforcement at each corner of the column and a connecting reinforcing bar that connects each main reinforcement restraint ring to each other. Improvements were made.
以下、この考案を図示した実施例（第２図およ
び第３図）に基づいて説明する。 This invention will be explained below based on illustrated embodiments (FIGS. 2 and 3).

する。 The figure shows an example in which H-shaped steel is used as the column steel frame 1, and shows the state before concrete is poured. The beam portion consists of only steel beams 2, and constitutes a composite structure of column steel reinforced concrete construction and beam steel construction.
図中３は柱主筋を示し、柱の四隅すなわち各隅
角部において主筋拘束環５が取り巻くようにして
これらの柱主筋３を拘束している。 In the figure, reference numeral 3 indicates column main reinforcements, and these column main reinforcements 3 are restrained by being surrounded by main reinforcement restraint rings 5 at the four corners of the column, that is, at each corner.

た梁鉄骨２のウエブと交差する箇所には貫通孔を
設けつなぎ鉄筋６を貫通させる。 In addition, each of the main reinforcing bars 5 is connected by a connecting reinforcing bar 6 whose both ends are bent to form a substantially U-shape, thereby serving as a substitute for a hoop reinforcing bar. The entire panel zone can be reinforced by arranging reinforcement by the combination of the main reinforcement restraining ring 5 and the connecting reinforcing bars 6 at appropriate pitches in the axial direction of the column. In this case, the connecting reinforcing bars 6 may have a larger diameter than ordinary hoop reinforcing bars or the like. In addition, a through hole is provided at a location where the beam steel frame 2 intersects with the web, and a connecting reinforcing bar 6 is passed through the through hole.
主筋拘束環５としては鉄筋あるいは鉄板等を溶
接して環状としたものが利用できる。また柱鉄骨
１もＨ形鋼に限らず断面十字状の鉄骨でもよい。 As the main reinforcement restraining ring 5, a ring-shaped ring formed by welding reinforcing bars or iron plates can be used. Further, the column steel frame 1 is not limited to H-shaped steel, but may be a steel frame having a cross-shaped cross section.
次に施工手順を説明すると、まず、隅角部の

の補強構造が得られる。 Next, the construction procedure will be explained. First, the required number of main reinforcement restraining rings 5 are inserted into the main reinforcement of the column at the corner. Set the connecting reinforcing bars 6. The main reinforcement restraining ring 5 is moved to a predetermined position and tied. The reinforcing structure of this invention can be obtained through the simple operations described above.
この考案は以上の構成からなり、次のような利
点、特徴を有する。 This invention has the above configuration and has the following advantages and features.
施工が非常に容易である。 Construction is very easy.
従来の一般補強法に比べ、梁鉄骨ウエブのフ
ープ用開孔数が少ない。 Compared to conventional general reinforcement methods, the number of holes for hoops in the beam steel web is smaller.
他の補強法では柱Ｈ鋼断面が大きい場合補強
困難となるが、本補強法は特に問題はない。 With other reinforcement methods, reinforcement becomes difficult when the cross-section of the column H steel is large, but with this reinforcement method there is no particular problem.
つなぎ鉄筋のアンカー方向が上下方向なの
で、コンクリートの充填を阻害しない。 The anchor direction of the connecting reinforcing bars is vertical, so it does not interfere with concrete filling.
