Description

本発明は、角形鋼管からなる柱部材と、H形断面部材からなる梁部材を備えた鉄骨構造の柱梁接合部に関わり、特に耐震性を要求される建築構造物に好適なものに関する。   The present invention relates to a steel beam-structured column-beam joint provided with a column member made of a square steel pipe and a beam member made of an H-shaped cross-section member, and more particularly to a structure suitable for a building structure requiring earthquake resistance.

角形鋼管柱は、板厚が薄くても大きな剛性が確保でき、耐火被覆や横材受けブラケットなどの取り付けが容易であるため、中低層建築物の鉄骨構造柱としてH形鋼やBOX柱のかわりに用いられる場合が多い。   Square steel pipe columns can secure large rigidity even when the plate thickness is thin, and it is easy to mount fireproof coverings and crosspiece brackets. Therefore, H-steel and BOX columns can be used as steel structure columns for medium- and low-rise buildings. It is often used for.

角形鋼管柱に、H形形状の梁を組みあわせた柱梁接合部では、H形形状のウエブに対向する位置が中空なため柱の管壁(柱フランジとも呼ぶ)の面外剛性が低く、結果として、取付け部の継手効率が低下する。   In the column-beam joint where an H-shaped beam is combined with a square steel pipe column, the position facing the H-shaped web is hollow, so the out-of-plane rigidity of the column tube wall (also called the column flange) is low, As a result, the joint efficiency of the attachment portion is reduced.

本発明において継手効率とは、「柱梁接合部の応力伝達能力が完全である場合に対する実際の応力伝達の割合」という意味である。正確には、H形鋼梁の「ウェブの継手効率」のことであり「梁が十分に塑性化した状態でウェブが実際に負担するモーメントの、ウェブ全断面有効とした場合のウェブの全塑性モーメントに対する比」と定義している。   In the present invention, the joint efficiency means “a ratio of actual stress transmission with respect to a case where the stress transmission capability of the beam-column joint is perfect”. To be exact, it is the “web joint efficiency” of the H-shaped steel beam, and “the total plasticity of the web when the entire cross-section of the web is valid for the moment that the web actually bears when the beam is sufficiently plasticized. It is defined as “ratio to moment”.

つまり、実際に良く用いられる中空断面柱による柱梁接合部では、柱の管壁の面外変形やスカラップの存在により、必ずしもウェブが全塑性状態にならないことを表現する指標である。   That is, it is an index that expresses that the web is not necessarily in a completely plastic state due to the out-of-plane deformation of the column wall of the column or the presence of scallops in the column-beam joint portion with a hollow cross-section column that is often used in practice.

ウェブの継手効率は、柱と梁ウェブの降伏点が等しく、かつ梁の高さが等しい場合は、近似的に柱幅厚比(柱の外径/柱の管厚)の逆数の1/2乗に比例することが知られている(非特許文献1)。従って、柱幅厚比を小さくして面外剛性を高くすれば、継手効率も向上する。   Web joint efficiency is approximately 1/2 of the inverse of the column width / thickness ratio (column outer diameter / column tube thickness) when the yield point of the column and beam web are equal and the beam height is equal. It is known that it is proportional to the power (Non-patent Document 1). Accordingly, if the column width thickness ratio is reduced to increase the out-of-plane rigidity, the joint efficiency is also improved.

図5に柱梁接合部の一例を示す。図は角形鋼管柱400にH形鋼からなる梁200を接合した接合部の部分断面図を示し、柱梁接合部の角形鋼管柱400は、ダイアフラム300a,300bを介して上下の角形鋼管柱100a,100bに接合されている。   FIG. 5 shows an example of a column beam joint. The figure shows a partial cross-sectional view of a joined portion in which a beam 200 made of H-shaped steel is joined to a square steel tube column 400. The square steel tube column 400 at the beam-to-column joint is formed by upper and lower square steel tube columns 100a via diaphragms 300a and 300b. , 100b.

角形鋼管柱にH形形状の梁を取り付ける柱梁接合部における、接合強度や耐震性を向上させるため、取付け部の継手効率を高くするべく柱管壁の面外剛性を上げる方法として、接合部に肉厚の厚い角形鋼管を用いたり、鋼管内部に内ダイヤフラムを設け、ウエブに対向する位置に縦スチフナなどを配置することが提案されている。   In order to improve the joint strength and earthquake resistance in the column beam joint that attaches the H-shaped beam to the square steel pipe column, the joint part is a method to increase the out-of-plane rigidity of the column pipe wall in order to increase the joint efficiency of the attachment part. It has been proposed to use a thick square steel pipe or to provide an inner diaphragm inside the steel pipe and to arrange a vertical stiffener or the like at a position facing the web.

特許文献1は、角形鋼管柱の柱梁接合部に関し、接合部となる鋼管柱に、厚肉継目無鋼管を熱間圧延成形し、柱梁接合部の上下の柱に対し、肉厚がより厚く、四隅コーナ部外面丸みが一致するものを用いて、単純な構造で高い強度が得られる柱梁接合部が記載されている。   Patent Document 1 relates to a column-to-beam joint of a square steel pipe column. A thick seamless steel pipe is hot-rolled into the steel pipe column to be a joint, and the thickness is higher than the upper and lower columns of the column-beam joint. A beam-to-column joint that has a simple structure and high strength is described by using a thick one that has rounded corners on the four corners.

特許文献2は、継手効率に優れる柱梁接合部を有する角形鋼管に関し、2本の溝形鋼500a、500bを突き合わせ溶接により角形鋼管とする際、接合部となる部分に溶接用裏当材600を取り付けた内ダイヤフラム700を設け、梁となるH形鋼のウエブに対向する位置に縦スチフナを取り付け、継手効率を向上させた角形鋼管が記載されている(図6)。   Patent Document 2 relates to a square steel pipe having a beam-column joint having excellent joint efficiency. When two groove steels 500a and 500b are made into a square steel pipe by butt welding, a backing material 600 for welding is formed on a portion to be a joint. A rectangular steel pipe is described in which an inner diaphragm 700 is attached and a vertical stiffener is attached at a position opposite to the H-shaped steel web to be a beam to improve joint efficiency (FIG. 6).

特許文献3には、柱梁接合部などを補強するために接合部となる部分に内ダイヤフラムを設けた角形鋼管の製造方法に関し、内ダイヤフラム700と溝形鋼100をエレクトロスラグ溶接で溶接する際、溶接孔部からの溶融金属の流出を防止するように内ダイヤフラムを形成することが記載されている(図7)。   Patent Document 3 relates to a method of manufacturing a rectangular steel pipe in which an inner diaphragm is provided at a joint portion in order to reinforce a column beam joint and the like, and when the inner diaphragm 700 and the channel steel 100 are welded by electroslag welding. It is described that an inner diaphragm is formed so as to prevent the molten metal from flowing out of the weld hole (FIG. 7).

しかしながら、特許文献1記載の角形鋼管は、厚肉継目無鋼管を熱間圧延成形して製造するので厚肉継目無鋼管の製品寸法によってその寸法が制約され、適用する建築構造物が限定される。特許文献2、3記載の方法は、鋼管内部に内ダイヤフラムを設けるため、角形鋼管製造工程が複雑で、製品コストが高く、また加工精度を確保するための手間が必要となる。   However, the square steel pipe described in Patent Document 1 is manufactured by hot rolling a thick-walled seamless steel pipe, so the dimensions are restricted by the product dimensions of the thick-walled seamless steel pipe, and the building structure to be applied is limited. . In the methods described in Patent Documents 2 and 3, since the inner diaphragm is provided inside the steel pipe, the manufacturing process of the square steel pipe is complicated, the product cost is high, and labor for ensuring the processing accuracy is required.

そこで、本発明は簡単な加工で、種々の寸法の角鋼管柱を高い加工精度で安価に製造することができ、耐震性にも優れた接合部の構造を提供することを目的とする。   Therefore, an object of the present invention is to provide a structure of a joint portion that can manufacture square steel pipe columns having various dimensions with high processing accuracy at low cost by simple processing, and is excellent in earthquake resistance.

In the case of constructing the joint 1 in FIG. 2, the following steps are preferable.
1. Combination process of square steel pipes Four square steel pipes 11 to 14 having a side length of 250 mm are combined so as to form a square and welded to form a square tubular body 1. When a hot-formed square steel pipe (for example, JFE Steel trade name JFE Kaku Hot) is used as the square steel pipes 11 to 14, the corner R portion is smaller than that of the cold-formed square steel pipe, and therefore, welding work can be simplified.

Therefore, when the rectangular tubular body 5 of the column-beam joint is extended to the full length of the column. It becomes possible to reduce the cross-sectional dimension of the column.

図4(b)は角形管状体5を構成する角形鋼管の内部にコンクリート7を充填した場合を示す。コンクリート7を充填する場合、複数本の角形鋼管を連通する孔を設けると、より剛性の高い角形管状体が得られて好ましい。内ダイアフラム形式において、有孔内ダイアフラムを用い、コンクリートを充填する場合に対して、充填性に優れる。   FIG. 4B shows a case in which concrete 7 is filled in the rectangular steel pipe constituting the rectangular tubular body 5. When filling the concrete 7, it is preferable to provide a hole for communicating a plurality of rectangular steel pipes because a rectangular tubular body with higher rigidity can be obtained. In the inner diaphragm type, a perforated inner diaphragm is used, and the filling property is excellent as compared with the case of filling concrete.

本発明は、柱梁接合部の角形管状体を構成する角形鋼管の本数は特に限定しない。H形断面梁のウエブからのモーメントが角形管状体に継手効率良く伝達できるように、角形鋼管の本数は適宜、選定することができ、例えば、角形管状体の辺長が、4本の角形鋼管の辺長で構成されるようにする、すなわち、16本の角形鋼管で角形管状体を構成することも可能である。   In the present invention, the number of rectangular steel pipes constituting the rectangular tubular body of the column beam joint is not particularly limited. The number of rectangular steel pipes can be selected as appropriate so that the moment from the web of the H-shaped cross-section beam can be efficiently transmitted to the rectangular tubular body. For example, the side length of the rectangular tubular body is four rectangular steel pipes. It is also possible to form a square tubular body with 16 square steel pipes.

また、接合部における梁の取り付け方向に応じて、角形鋼管の形状を矩形断面とすることも可能である。例えば、2本の梁が、水平方向にのみ取り付けられる場合は、2本の矩形断面の角形鋼管で角形管状体を構成する。   Moreover, it is also possible to make the shape of a square steel pipe into a rectangular cross section according to the attachment direction of the beam in a junction part. For example, when two beams are attached only in the horizontal direction, a rectangular tubular body is constituted by two rectangular steel pipes having a rectangular cross section.
