Description

本考案は、Ｈ形鋼の鉄骨柱及び鉄骨梁の接合構造に関する。   The present invention relates to a joint structure of steel columns and steel beams made of H-shaped steel.

従来、Ｈ形鋼の鉄骨柱及び鉄骨梁の接合構造としては、例えば、下記特許文献１に示すようなＴ字状の接合金物、いわゆるスプリットティーを用いたものが知られている。特許文献１において、接合金物のフランジ部は、複数のボルト挿通孔を設け、鉄骨柱に接する接合金物のボルト挿通孔からその端部にかけて傾斜面を形成し、鉄骨柱のフランジ部に当てた状態で、ボルト挿通孔に対して挿通した高力ボルトで締め付けて鉄骨柱に引張接合している。一方、接合金物のウェブ部は、複数のボルト挿通孔を設け、鉄骨梁のフランジ部に当てた状態で、ボルト挿通孔に対して挿通した高力ボルトで締め付けて鉄骨梁に接合している。特許文献１の接合金物によれば、接合金物に引張力が作用して接合金物のフランジ部に曲げ変形が生じた場合、鉄骨柱のフランジ部に接するボルト挿通孔を支点に回転するので、テコの反力が生じず、引張耐力をやわらげることができる。   Conventionally, as a joining structure of a steel column and a steel beam of an H-shaped steel, for example, a structure using a T-shaped joining hardware as shown in Patent Document 1 below, that is, a so-called split tee is known. In Patent Document 1, the flange portion of the metal joint is provided with a plurality of bolt insertion holes, an inclined surface is formed from the bolt insertion hole of the metal joint in contact with the steel column to the end thereof, and is applied to the flange portion of the steel column Then, it is tightened with a high-strength bolt inserted into the bolt insertion hole, and is tension-bonded to the steel column. On the other hand, the web portion of the metal fitting is provided with a plurality of bolt insertion holes, and is fastened with a high-strength bolt inserted into the bolt insertion hole and joined to the steel beam while being in contact with the flange portion of the steel beam. According to the joint metal object of Patent Document 1, when a tensile force acts on the joint metal part and bending deformation occurs in the flange part of the joint metal part, the bolt insertion hole that contacts the flange part of the steel column rotates about the fulcrum. The reaction force is not generated and the tensile strength can be reduced.

また、下記特許文献２に示すような羽子板状の接合金物、いわゆるパドルボルトを用いたものも知られている。特許文献２において、接合金物は、一端にボルト部を設け、他端にボルト挿通孔を有した平板部を形成している。接合金物のボルト部は、鉄骨柱のフランジ部に設けたボルト挿通孔に対して挿通して締め付け、鉄骨柱に引張接合している。一方、接合金物の平板部は、鉄骨梁のフランジ部に当てた状態で、ボルト挿通孔に対して挿通した高力ボルトで締め付けて鉄骨梁に接合している。特許文献２の接合金物によれば、鉄骨柱の建入れ精度が少々悪くても、ボルト部に螺合した調整用ナットを回転させることにより、寸法調整を行うことができ、操作の容易性及び施工性の向上を図ることができる。   Further, there are known ones using a battledore-like joint metal as shown in Patent Document 2 below, so-called paddle bolts. In Patent Document 2, the metal joint is provided with a bolt portion at one end and a flat plate portion having a bolt insertion hole at the other end. The bolt portion of the joint metal is inserted and tightened into a bolt insertion hole provided in the flange portion of the steel column, and is tension-bonded to the steel column. On the other hand, the flat plate portion of the metal fitting is joined to the steel beam by tightening with a high-strength bolt inserted into the bolt insertion hole in a state where it is in contact with the flange portion of the steel beam. According to the joint hardware of Patent Document 2, even if the accuracy of erection of the steel column is a little worse, it is possible to adjust the dimensions by rotating the adjusting nut screwed into the bolt portion, and the ease of operation and The workability can be improved.

また、下記特許文献３に示すようなＬ字或いは底板部と、前記底板部に対して直角に立ち上がり、且つ前記底板部よりも先方が延びた挿通部位を有する側板部を有した接合金物による接合方法もある。この場合、鉄骨柱のフランジ部は、鉄骨梁のフランジ部と交差する部位にスリット孔を形成し、当該スリット孔に対して前記側板部の挿通部位を挿通し、当該側板部の挿通部位を前記鉄骨柱のウェブ部に対接した状態で固定し、前記接合金物の底板部を前記鉄骨梁のフランジ部に対接した状態で固定している。   Also, joining by a metal joint having an L-shaped or bottom plate portion as shown in Patent Document 3 below and a side plate portion having an insertion portion that rises at a right angle to the bottom plate portion and extends beyond the bottom plate portion. There is also a method. In this case, the flange portion of the steel column forms a slit hole in a portion intersecting with the flange portion of the steel beam, the insertion portion of the side plate portion is inserted into the slit hole, and the insertion portion of the side plate portion is It fixes in the state which contacted the web part of the steel column, and is fixed in the state which contacted the flange part of the steel beam with the bottom plate part of the metal fitting.

また、下記特許文献４に示すような鉄骨平板の接合金物で対接した状態で固定するものがある。この事例において、前記接合金物は、２枚１組の鉄骨平板で形成し、且つ先方が延びた挿通部位を有し、鉄骨柱のフランジ部は、前記鉄骨梁のフランジ部と交差する部位にスリット孔を形成し、当該スリット孔に対して接合金物を挿通し、鉄骨柱のウェブ部に対接した状態で固定し、さらに、鉄骨梁のフランジ部の外側に固定した鉄骨平板部に対接した状態で固定している。   Moreover, there exists a thing fixed in the state which faced with the joining metal object of the steel frame flat plate as shown to the following patent document 4. FIG. In this case, the metal fitting is formed of a set of two steel flat plates and has an insertion part extending forward, and the flange part of the steel column is slit at a part intersecting the flange part of the steel beam. A hole is formed, a metal fitting is inserted into the slit hole, fixed in a state of being in contact with the web portion of the steel column, and further in contact with a steel plate portion fixed outside the flange portion of the steel beam. It is fixed in the state.

しかしながら、従来の上記接合構造で用いる接合金物は、接合する対象物である鉄骨柱と鉄骨梁に固定するための複数のボルト挿通孔や接合金物挿通孔を設ける必要があるため、引張力や圧縮力、剪断力に対する耐力が弱いという問題がある。また、スプリットティーのウェブ部やパドルボルトは、鉄骨柱のフランジ部上において接合金物を接合しているため、鉄骨梁からの力の伝達は、常に鉄骨柱のフランジ部を介するという問題がある。すなわち、鉄骨柱のフランジ部は、その短手方向中心位置から離れるに従い、当該フランジ部に対して直角方向にかかる引張力や圧縮力に対する耐力が弱く、過度に大きい引張力や圧縮力が、接合金物を介して鉄骨柱のフランジ部に伝達された場合、この部位において接合金物だけでなく、鉄骨柱のフランジ部も破損する恐れがあるという問題がある。このような事情により、スプリットティーやパドルボルト等の接合金物や、ボルト、ナット等の緊締金具、鉄骨柱のフランジ部等の構成部材を高強度鋼、肉厚、太径等に設計することにより接合構造の耐力を得る対応をとる傾向があるが、ボルト挿通孔等により不足する耐力を補強する必要もあり、ガセットプレートや補強鉄骨等の複数の補強部材も用いなければならないという問題がある。また、底板部と、前記底板部に対して直角に立ち上がり、かつ前記底板部よりも先方が延びた挿通部位を有する側板部とを有した接合金物は、前記底板部と側板部での力の伝達が捩れる問題がある。ボルト及び接合金物の挿通孔等により不足する耐力を補強する必要もある。また、２枚１組の鉄骨平板による接合金物もボルト及び接合金物の挿通孔等により不足する耐力を補強する必要もあり、補強鋼板等の複数の補強部材も用いなければならないという問題がある。この結果、構成部材の製造コストや、構成部材の増大による作業コスト、搬送コスト等が高くなり、工期も遅延するという問題がある。   However, it is necessary to provide a plurality of bolt insertion holes and joint hardware insertion holes for fixing to the steel column and steel beam, which are the objects to be joined, in the conventional joint metal structure used in the above joint structure. There is a problem that resistance to force and shear force is weak. In addition, since the split tee web portion and the paddle bolt are joined to each other on the flange portion of the steel column, there is a problem that force transmission from the steel beam always passes through the flange portion of the steel column. That is, as the flange portion of the steel column moves away from the center position in the short direction, the resistance to tensile force and compressive force in the direction perpendicular to the flange portion is weak, and excessively large tensile force and compressive force are When transmitted to the flange portion of the steel column through the hardware, there is a problem that not only the joint hardware but also the flange portion of the steel column may be damaged at this portion. Because of these circumstances, by designing components such as split tees and paddle bolts, tightening fittings such as bolts and nuts, flanges of steel columns, etc. to high strength steel, wall thickness, large diameter, etc. There is a tendency to take measures to obtain the strength of the joint structure, but it is necessary to reinforce the strength that is deficient by bolt insertion holes or the like, and there is a problem that a plurality of reinforcing members such as gusset plates and reinforcing steel frames must also be used. Further, the joint hardware having the bottom plate portion and the side plate portion having the insertion portion that stands up at right angles to the bottom plate portion and extends beyond the bottom plate portion is the force of the force at the bottom plate portion and the side plate portion. There is a problem of twisting transmission. It is also necessary to reinforce the insufficient proof stress due to the insertion holes of bolts and joint hardware. In addition, there is a problem in that a metal joint made of a set of two steel plates also needs to reinforce the strength that is insufficient due to bolts and insertion holes of the metal joint, and a plurality of reinforcing members such as reinforcing steel plates must be used. As a result, there is a problem that the manufacturing cost of the component members, the work cost due to the increase in the component members, the conveyance cost, etc. are increased, and the construction period is also delayed.

このような問題に着目し、本考案は、簡素な構成の接合金物により、鉄骨柱及び鉄骨梁にはボルト及び接合金物の挿通孔等による断面欠損をなくし、鉄骨柱及び鉄骨梁にかかる引張力、圧縮力、剪断力に対する十分な耐力を得ることができ、さらに、コストの低減や工期の短縮を図ることができる、鉄骨柱及び鉄骨梁の接合構造を提供することを目的とする。   Paying attention to such problems, the present invention eliminates cross-sectional defects due to bolts and insertion holes in the steel columns and steel beams with a simple structure of the metal fittings, and the tensile force applied to the steel columns and steel beams. An object of the present invention is to provide a steel column and steel beam joint structure capable of obtaining sufficient resistance to compressive force and shearing force, and further capable of reducing cost and shortening the construction period.

本考案の鉄骨柱及び鉄骨梁の接合構造は、ウェブ部及びウェブ部の両側に設けられたフランジ部を有する鉄骨柱と、ウェブ部及びウェブ部の両側に設けられたフランジ部を有する鉄骨梁とを接合金物により接合する鉄骨柱及び鉄骨梁の接合構造において、接合金物は、２枚１組の鉄骨平板の組み合わせで構成し、鉄骨柱のフランジ部の外側左右面に有する鉄骨平板と鉄骨梁のフランジ部の外側上下面に有する鉄骨平板に対して、接合金物で対接した状態で固定し、さらに、鉄骨柱のフランジ部の外側左右面に有するガセットプレートと鉄骨梁のウェブを、対接した状態で固定したことを特徴とする。   The steel column and steel beam joint structure of the present invention includes a steel column having flange portions provided on both sides of the web portion and the web portion, and a steel beam having flange portions provided on both sides of the web portion and the web portion. In the joint structure of a steel column and a steel beam, which are joined by a joint metal, the joint hardware is composed of a combination of two steel plates, and the steel plate and the steel beam on the outer left and right sides of the flange portion of the steel column. Fixed to the steel flat plate on the outer upper and lower surfaces of the flange part in a state of being in contact with the joint metal, and further, the gusset plate and the steel beam web on the outer left and right sides of the flange part of the steel column were in contact with each other. It is characterized by being fixed in a state.

また、鉄骨柱のフランジ部の外側左右面に有する鉄骨平板を、接合金物と対接した状態で固定するガセットプレートと鉄骨梁のウェブと対接した状態で固定するガセットプレートを一体とした１枚の鉄骨平板と鉄骨梁のフランジ部の外側上下面に有する鉄骨平板及び鉄骨梁のウェブを、対接した状態で固定したことを特徴とする。   In addition, a single piece of a gusset plate for fixing the steel flat plates on the outer left and right side surfaces of the flange portion of the steel column in contact with the metal fitting and the gusset plate for fixing in contact with the steel beam web The steel plate and the steel beam web on the upper and lower outer surfaces of the flange portion of the steel beam are fixed in contact with each other.

これにより、接合金物と鉄骨柱のフランジ部の外側左右面に有する鉄骨平板と鉄骨梁のフランジ部の外側上下面に有する鉄骨平板以外は、ボルト及び接合金物の挿通孔による断面の欠損部分がなくなる。   As a result, there is no missing portion of the cross section due to the insertion holes of the bolts and the joint hardware other than the steel flat plates possessed on the outer left and right surfaces of the flange part of the joint hardware and the steel column and the steel plate plates on the outer top and bottom faces of the flange part of the steel beam. .

本考案の鉄骨柱及び鉄骨梁の接合構造によれば、鉄骨柱及び鉄骨梁に断面欠損がない状態で使用することを可能にしているため、接合金物を介して鉄骨柱及び鉄骨梁にかかる引張力、圧縮力、剪断力を円滑に伝達することができ、これにより、これらの力に対する十分な耐力を得ることができる。この結果、接合構造の十分な耐力を得るために、接合金物及び構成部材等を高強度鋼、肉厚、太径等で設計したり、複数の補強部材を用いたりする必要がなく、さらにデッキプレート等床の敷き込みに必要な受材が不要となり現場が簡素化され、コストの低減や工期の短縮を図ることができる。   According to the steel column and steel beam joint structure of the present invention, it is possible to use the steel column and steel beam without a cross-sectional defect, so that the tension applied to the steel column and steel beam via the joint hardware Force, compressive force, and shear force can be transmitted smoothly, and thereby sufficient resistance to these forces can be obtained. As a result, in order to obtain sufficient strength of the joint structure, it is not necessary to design the joint hardware and component members with high-strength steel, wall thickness, large diameter, etc., or to use a plurality of reinforcing members. The receiving material necessary for laying the floor such as a plate is not required, the site is simplified, and the cost and the construction period can be shortened.

Since the steel column 1 and the steel beam 2 are free from defects by being provided, they are not affected by the tensile force or compressive force in the direction perpendicular to the flange portion 12 of the steel column 10 at this portion. Further, the tensile force, the compressive force, and the shearing force applied to the steel column 1 and the steel beam 2 can be smoothly transmitted by changing the respective forces transmitted to this portion by the bonding hardware 3 in the perpendicular direction. That is, the tensile force, the compressive force, and the shearing force transmitted on the flange portion 22 of the steel beam 2 are transmitted to the flange gusset plate 23 that is fixed to the outside of the upper and lower surfaces of the flange portion 22 of the steel beam 2, and It is transmitted from the set of metal fittings 3 onto the flange gusset plate 13 or the gusset plate 17 of the steel column 1. On the other hand, the tensile force, the compressive force, and the shearing force transmitted from the flange gusset plate 13 or the gusset plate 17 of the steel column 1 to the set of two joints 3 are outside the upper and lower surfaces of the flange portion 22 of the steel beam 2.
