【考案の詳細な説明】 〔産業上の利用分野〕 この考案は、主に高強度コンクリートおよび高強度鉄
筋を使用した鉄筋コンクリート構造物の柱・梁接合部構
造に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention mainly relates to a column-beam joint structure of a reinforced concrete structure using high-strength concrete and high-strength reinforcing bars.
一般に、鉄筋コンクリート構造の建物において、鉄筋
およびコンクリートとして高強度鉄筋（SD60以上）と高
強度コンクリート（Fc＝600kg/cm2以上）を使用した場
合、普通の鉄筋およびコンクリートを使用した場合より
も強度が著しく向上するが、その一方で部材応力は全体
に大きくなり、特に柱と梁との接合部には相当大きな応
力が生じる。このため、通常の断面サイズでは鉄筋の被
りを充分確保できないために、主筋端部では定着不足を
きたす。In general, in a building with reinforced concrete structure, when high-strength reinforcing bars (SD60 or more) and high-strength concrete (Fc = 600 kg / cm 2 or more) are used as reinforcing bars and concrete, the strength is higher than when ordinary reinforcing bars and concrete are used. Although it is remarkably improved, the member stress is increased as a whole, and considerably large stress is generated particularly at the joint between the column and the beam. For this reason, since the covering of the reinforcing bar cannot be sufficiently secured with a normal cross-sectional size, the fixation of the main reinforcing bar end is insufficient.
このことは、柱・梁接合部でも同じで、この部分の荷
重−変形曲線はいわゆるスリップ型の構造性能を示し、
梁主筋が抜け出すおそれがある。This is the same for the column-beam joints, and the load-deformation curve of this part shows so-called slip type structural performance,
The main beam of the beam may come out.
このため、鉄筋コンクリート構造の建物に高強度コン
クリートを使用する場合には、柱・梁接合部における鉄
筋の被りを充分に確保できるように柱径を相当割り増し
する必要があるため、室内空間が柱や梁などの構造体に
よって相当狭められてしまうだけでなく、部材断面を割
り増しした分だけコンクリートの使用量も多くなってし
まい、高強度コンクリートを使用したメリットを充分に
発揮できないことが多い。For this reason, when using high-strength concrete in a building with a reinforced concrete structure, it is necessary to increase the column diameter considerably in order to ensure sufficient coverage of the reinforcing bars at the column-beam joints. Not only is it considerably narrowed down by structures such as beams, but the amount of concrete used is also increased due to the additional cross-section of the members, and it is often the case that the advantages of using high-strength concrete cannot be fully exerted.
