【従来技術およびその問題点】[Prior art and its problems]

事務所ビル、ショッピングセンター、倉庫等の建築物には、鉄筋コンクリート 柱と鉄骨梁とからなる構造形式が採用されている。この構造形式はスパンを長く することができ、また、施工の合理化を図ることができる点で優れているが、鉄 筋コンクリートおよび鉄骨という異種構造部材を組み立てるものであるから、こ れらの部材の接合部における応力伝達が重要な課題となっている。 Buildings such as office buildings, shopping centers, and warehouses have a structural type consisting of reinforced concrete columns and steel beams. This structure type is excellent in that it can have a long span and can streamline construction, but since it is used to assemble dissimilar structural members such as reinforced concrete and steel frames, these members are used. The stress transmission in the joint of the has become an important issue.

【0003】 実開昭62−75105号公報には、鉄筋コンクリート柱の梁接合部のフープ 筋および型枠を省略して、施工の簡略化を図るべく、横断面が方形の鉄筋コンク リート柱の接合部のコンクリート内に、ウェブの先端にフランジが垂直に形成さ れた平面十字形梁接合金物を設置し、更に、この鉄筋コンクリート柱の四面を囲 む板状の梁接合部の補強金物を設け、横T形断面の梁の接合ブラケットのフラン ジを前記補強金物に重ねて、前記平面十字形梁接合金物の先端のフランジを高力 ボルトによってボルト止めすることにより当該接合ブラケットを取り付け、かつ 、該接合ブラケットに鉄骨梁を接合する構造が開示されている。 しかしながら、この接合構造は接合金物に取り付ける部材点数が相当多く、複 雑な構造となっている。Japanese Utility Model Laid-Open No. 62-75105 discloses a method for joining reinforced concrete columns having a rectangular cross section in order to simplify the construction by omitting the hoop reinforcements and formwork at the beam joints of reinforced concrete columns. In the concrete of the section, a plane cross beam joint metal with a flange formed vertically at the tip of the web is installed, and further, a plate-shaped beam joint reinforcement that surrounds the four sides of this reinforced concrete column is installed. The flange of the joining bracket of the beam having the transverse T-shaped cross section is superposed on the reinforcing metal fitting, and the joining bracket is attached by bolting the flange at the tip of the plane cross-shaped beam joining fitting with a high-strength bolt, and A structure for joining a steel beam to a joining bracket is disclosed. However, this joining structure is a complicated structure because the number of members attached to the joining metal is considerably large.

【0004】 また、特開平1−290844号公報には、鉄筋コンクリート柱と鉄骨梁とを 十分な機械的強度を保って接合するために、鉄筋コンクリート柱と鉄骨梁の接合 部を鋼板で覆い、この鋼板に鉄骨梁の上下フランジにそれぞれ連結する十文字状 の水平ダイアフラムを上記鋼板から外方に突出して設け、更に、この水平ダイア フラムにコンクリート充填用穴および柱鉄筋貫通用穴を設けた接合構造が開示さ れている。 この接合構造は接合部を鋼板で覆っているので、パネルゾーンにおけるコンク リートの拘束効果が大きい点で優れているが、接合部を覆う鋼板から水平ダイア フラムを突設させるなど、鋼板の加工作業が煩雑となるという問題点を有してい る。また、力学的にも、パネルゾーン内に突設する水平ダイアフラムが引張り降 伏を起こす虞がある。Further, in Japanese Laid-Open Patent Publication No. 1-290844, in order to join a reinforced concrete column and a steel beam with sufficient mechanical strength, the joint between the reinforced concrete column and the steel beam is covered with a steel plate, and this steel plate is used. Disclosed is a joint structure in which cross-shaped horizontal diaphragms that are respectively connected to the upper and lower flanges of the steel beam are provided so as to project outward from the steel plate, and that the horizontal diaphragm is provided with a concrete filling hole and a column reinforcing bar penetrating hole. It is being touched. Since this joint structure covers the joint with steel plates, it is excellent in that the concrete restraint effect in the panel zone is large, but the steel plate processing work such as projecting a horizontal diaphragm from the steel plate covering the joint Has the problem that it becomes complicated. In addition, mechanically, the horizontal diaphragm protruding in the panel zone may be tensilely yielded.

【実施例】【Example】

以下、本考案の好適な実施例を図面に基づき説明する。 図1は本考案に係る鉄筋コンクリート柱と鉄骨梁の接合部に用いる接合金物の 組立図であり、該接合金物10は角筒形の柱接続部20と十字形の梁接続金物3 0A、30Bとから構成される。 Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an assembly drawing of a metal joint used for a joint between a reinforced concrete column and a steel beam according to the present invention. The metal joint 10 includes a prismatic column connection portion 20 and a cross-shaped beam connection hardware 30A, 30B. Composed of.

【0009】 柱接続部20は鋼管または鋼板から製造することができ、その高さは鉄骨梁1 2となるH形鋼の梁成に等しくする。鋼管により製造する場合は、柱接続部20 の組立が容易となり、一方、鋼板を用いて柱接続部20を製造する場合には、次 に述べる切欠部22の加工が容易となる。 柱接続部20の上下端部には、後記する梁接続金物30A、30Bを嵌合させ るためのT字形の切欠部22を4個ずつ形成する。図1において、切欠部22は 柱接続部20の上下端部と梁接続金物30A、30Bのフランジ面が整合するよ うに切り欠かれているが、これに限らずもっと深く切り欠いて、梁接続金物30 A、30Bが柱接続部20の内部に位置するようにしてもよい。The column connection portion 20 can be manufactured from a steel pipe or a steel plate, and its height is made equal to that of an H-shaped steel beam to be the steel frame beam 12. In the case of manufacturing with a steel pipe, the column connecting portion 20 is easily assembled, while in the case of manufacturing the column connecting portion 20 using a steel plate, the notch 22 described below is easily processed. Four T-shaped notches 22 are formed in the upper and lower ends of the column connecting portion 20 for fitting beam connecting metal pieces 30A and 30B, which will be described later. In FIG. 1, the notch 22 is notched so that the upper and lower ends of the column connection part 20 and the flange surfaces of the beam connection fittings 30A, 30B are aligned, but the notch 22 is not limited to this, and the notch 22 may be used to connect the beam connection The metal fittings 30A and 30B may be located inside the pillar connection portion 20.

【0010】 梁接続金物30A、30Bは、十字形のフランジ32と、このフランジ32に 対して垂直に設けたリブ34とからなる。従って、梁接続金物30A、30Bの 断面はT字形となり、所謂、カットティー梁となる。 フランジ32の幅は鉄骨梁12のフランジ幅と等しくする。また、リブ34の 高さには格別の制限はないが、梁接続金物30A、30Bが引張り降伏を起こさ ない程度の高さがあればよい。The beam connection hardware 30A, 30B includes a cross-shaped flange 32 and a rib 34 provided perpendicularly to the flange 32. Therefore, the cross section of the beam connecting hardware 30A, 30B is T-shaped, which is a so-called cut tee beam. The width of the flange 32 is equal to the flange width of the steel beam 12. Further, the height of the rib 34 is not particularly limited, but may be any height as long as the beam connecting hardware 30A, 30B does not cause tensile yielding.

【0011】 図2は前記接合金物10を用いた鉄筋コンクリート柱14と鉄骨梁12の接合 部の斜視図である。 鉄筋コンクリート柱14に鉄骨梁12を接合するには、例えば、柱主筋16を 圧接後、前記柱接続部20の上下端部に梁接続金物30A、30Bを溶接して組 立てた接合金物10を地上にて柱頭部に固定した後、プレキャスト製の鉄筋コン クリート柱14を所定位置に立設する。FIG. 2 is a perspective view of the joint between the reinforced concrete column 14 and the steel beam 12 using the joint metal 10. In order to join the steel beam 12 to the reinforced concrete column 14, for example, after the column main bar 16 is pressure-welded, the beam connecting hardware 30A, 30B is welded to the upper and lower ends of the column connecting portion 20 to form the weld metal assembly 10 on the ground. After fixing to the head of the column, a precast rebar concrete column 14 is erected at a predetermined position.

【0012】 次に、鉄骨梁12の端部を四方から寄せて、鉄骨梁12のフランジ端部と梁接 続金物30A、30Bのフランジ32の各端部とを溶接する。また、鉄骨梁12 のウェブにはガセット18を当てて柱接続部20の外周部にボルト接合する。 本考案において、接合金物10と鉄骨梁12の接合には種々の方法を採用する ことができ、例えば、図3は柱・梁接合部の中央部縦断側面図であるが、同図の 左半部に示すように、鉄骨梁12のフランジ端部と梁接続金物30A、30Bの フランジ32の各端部とにガセット18を当ててボルト接合している。なお、図 3の右半部は前記図2の縦断側面図を示している。Next, the ends of the steel beam 12 are brought close to each other from the four sides, and the flange end of the steel beam 12 and each end of the flanges 32 of the beam connecting hardware 30A, 30B are welded. A gusset 18 is applied to the web of the steel frame beam 12 and bolted to the outer peripheral portion of the column connecting portion 20. In the present invention, various methods can be adopted for joining the joint metal 10 and the steel beam 12, for example, FIG. 3 is a vertical cross-sectional side view of a central portion of a column-beam joint. As shown in the section, a gusset 18 is applied to the flange end of the steel beam 12 and each end of the flange 32 of the beam connecting hardware 30A, 30B for bolting. The right half of FIG. 3 shows the vertical side view of FIG.

【0013】 柱と梁を接続した後、接合金物10の内部にコンクリートを打設する。パネル ゾーン内には部分的にリブ34が延びているだけであるから、コンクリートはス ムーズに充填される。After connecting the column and the beam, concrete is placed inside the metal joint 10. The concrete is smoothly filled because the ribs 34 only partially extend within the panel zone.

【0014】 上記接合構造により、鉄骨梁12の応力は梁接続金物30A、30Bおよび柱 接続部20を介して、確実に鉄筋コンクリート柱14に伝達される。また、角型 鋼管形状の柱接続部20がパネルゾーン内部のコンクリートを拘束するので、接 合部の力学的性状が良好となる。With the above-described joint structure, the stress of the steel frame beam 12 is reliably transmitted to the reinforced concrete column 14 via the beam connecting hardware 30A, 30B and the column connecting portion 20. Further, since the prismatic steel pipe-shaped column connection portion 20 restrains the concrete inside the panel zone, the mechanical properties of the connection portion are improved.

【考案の効果】[Effect of the device]

本考案は鉄筋コンクリート柱と鉄骨梁の接合部に接合金物を設け、この接合金 物内を貫通する梁接続金物の断面形状をT字形とする構造を採用することにより 、鉄骨梁の応力を確実に鉄筋コンクリート柱に伝達させることができ、接合部に 所要の耐力を確保することができる。 The present invention ensures the stress of the steel beam by adopting a structure in which a joint metal is provided at the joint between the reinforced concrete column and the steel beam, and the cross-sectional shape of the beam connecting metal penetrating through the joint is T-shaped. It can be transmitted to a reinforced concrete column and the required yield strength can be secured at the joint.

【0016】 また、本考案は接合部としてシンプルな構造を採用しているから、当該接合部 に使用する鋼管や鋼板の加工および組立が極めて容易であるという優れた効果を 有する。Further, since the present invention adopts a simple structure for the joint, it has an excellent effect that the processing and assembling of the steel pipe and the steel plate used for the joint are extremely easy.
