Description

本発明は、例えば、建築構造物等において、中空状の鋼管などを用いた柱部材の上下端部間を、上下方向に連結するために用いられる柱継手構造に関するものである。   The present invention relates to a column joint structure that is used, for example, in a building structure or the like to connect vertically between upper and lower ends of a column member using a hollow steel pipe or the like.

従来は、中空状の鋼管などを用いた柱部材の継手構造としては、図９，１０に示すような、仮組立て用の仮設板部材７１，７２を使用して、四角筒状の鋼管などの柱部材７４，７５の端部同士の位置合わせをした後、その端部同士を溶接で接合する溶接継手構造がほとんどであった（例えば特許文献１に記載の従来例参照）。   Conventionally, as a joint structure of a column member using a hollow steel pipe or the like, a temporary plate member 71 or 72 for temporary assembly as shown in FIGS. Most of the welded joint structures are formed by aligning the ends of the column members 74 and 75 and then joining the ends by welding (see, for example, the conventional example described in Patent Document 1).

同図に示す仮設板部材７１は、四角筒状の鋼管などの柱部材７４下端部の周部４面各幅の、上下方向に伸びる各中心線に沿って、その側辺が溶接により柱部材７４に接合され、やはり四角筒状の鋼管などの柱部材７５上端部の周部４面各幅の、上下方向に伸びる各中心線に沿って、その側辺が溶接により柱部材７５に接合される。   The temporary plate member 71 shown in the figure has a column member that is welded along the center line extending in the vertical direction of each width of each of the four peripheral surfaces of the column member 74 such as a square tubular steel pipe. 74, and the side edges of the circumferential member 4 surfaces of the upper end of the column member 75 such as a square tube-shaped steel pipe are joined to the column member 75 by welding along respective center lines extending in the vertical direction. The

そして、柱部材７４の下端部と柱部材７５の上端部を突き合わせて、柱部材７４，７５それぞれに接合した２枚の仮設板部材７１に、１枚又は２枚の仮設板部材７２を片面側又は両面側に重ねて配置し、仮設板部材７１，７２間をボルトとナットで締め付けて互いを固定する（図１０参照）。   Then, the lower end portion of the column member 74 and the upper end portion of the column member 75 are abutted, and one or two temporary plate members 72 are placed on one side of the two temporary plate members 71 joined to the column members 74 and 75 respectively. Alternatively, they are arranged on both sides, and the temporary plate members 71 and 72 are fastened with bolts and nuts to fix each other (see FIG. 10).

このようにして、柱部材７４，７５相互間の水平断面方向の位置合せをする仮組立てが終わったら、柱部材７４，７５の端面間を溶接Ｗで接合するようになっている（図１０参照）。   Thus, after the temporary assembly which aligns the horizontal cross-section direction between the column members 74 and 75 is completed, the end surfaces of the column members 74 and 75 are joined by welding W (see FIG. 10). ).

しかしながら、このような柱部材の溶接を用いた継手構造は、その施工が現場で溶接作業を行うために風及び雨など天候の影響を受けると共に、溶接作業には熟練した溶接技能者を必要とし、また溶接後に溶接部の検査が必要となる。さらに、仮組立て用の仮設板部材７１，７２が必要となり、それらは柱部材７４，７５の外側に大きく突出するため、柱部材７４，７５間の溶接後に溶断して除去しなければならなかった。   However, such a joint structure using column member welding is affected by the weather such as wind and rain because the construction is performed on site, and a welding engineer is required for the welding operation. In addition, inspection of the welded portion is necessary after welding. Further, temporary plate members 71 and 72 for temporary assembly are required, and they protrude greatly to the outside of the column members 74 and 75. Therefore, they have to be melted and removed after welding between the column members 74 and 75. .

そのため、溶接を用いない継手構造として、例えば特許文献１に記載されている実施の形態のような、高力ボルトを用いたボルト接合による継手構造が各種提案されている。このような接合に高力ボルトを用いた中空状の柱部材の継手構造は、溶接や仮組立て用の仮設板部材を用いない接合構造を提供することや、接合に用いられる部材が柱部材の外側に大きく突出するのを防止することを目的としている。   For this reason, various joint structures using bolt joints using high-strength bolts, such as the embodiment described in Patent Document 1, have been proposed as joint structures that do not use welding. The joint structure of hollow column members using high-strength bolts for such joining provides a joining structure that does not use a temporary plate member for welding or temporary assembly, or the member used for joining is a column member. The purpose is to prevent it from projecting greatly to the outside.

特開平７−１２７１４２号JP-A-7-127142

しかしながら、このような中空状の柱部材の接合に高力ボルトを用いた継手構造においては、ボルトの挿入及び締結の作業を、中空状の柱部材の外側から行わなければならないため、例えば特許文献１の図５に示す植込みボルト２５のような特殊なボルトを用いる必要がある。   However, in such a joint structure using high-strength bolts for joining hollow column members, bolts must be inserted and fastened from the outside of the hollow column members. It is necessary to use a special bolt such as the stud bolt 25 shown in FIG.

また、接合される柱部材の内側もしくはその内側の継手部材にナットを前もって取り付けておくか、または接合される柱部材内側の継手部材にネジ孔を形成しておく必要がある。接合される柱部材の外側からボルト締結作業を行う場合、外側からナットを締付ける方法と、外側からボルトの頭部を締付ける方法がある。   Moreover, it is necessary to attach a nut beforehand to the inner side of the column member to be joined or a joint member inside the column member, or to form a screw hole in the joint member inside the column member to be joined. When the bolt fastening operation is performed from the outside of the column members to be joined, there are a method of fastening the nut from the outside and a method of fastening the head of the bolt from the outside.

外側からナットを締付けて行う場合は、ナットの高さ寸法はボルトの頭部の高さ寸法より大きく、またボルトのネジ部にはナットの高さ寸法より長く外側に突出する余長部が必要であるため、依然として締結部材が接合される柱部材の外側に大きく突出してしまうという問題がある。また外側からボルトの頭部の締め付けを行う場合は、内側のナットが固定されていないとボルトとナットが共に回転して充分な締結を行なうことができないという問題がある。   When tightening the nut from the outside, the height of the nut is larger than the height of the head of the bolt, and the screw thread of the bolt needs an extra length that protrudes outward longer than the height of the nut. Therefore, there is still a problem that the fastening member protrudes greatly to the outside of the column member to be joined. Further, when the bolt head is tightened from the outside, there is a problem that if the inner nut is not fixed, the bolt and the nut rotate together and sufficient fastening cannot be performed.

また、このような高力ボルトを用いた継手構造の施工においては、仮組立て時の仮止めに使用する仮ボルトに、本組立て用のボルトを使用する場合は、ボルトを傷める場合が多く、その場合は充分な締結ができなくなる。このため、上記仮ボルトに本組立て用のボルトを使用することは原則としてできない。このため、組立て後に仮ボルトを本組立て用のボルトと取替える作業を行う必要があり、その作業に手間が掛かるという問題がある。   Also, in the construction of joint structures using such high-strength bolts, when using the bolts for this assembly as temporary bolts used for temporary fixing during temporary assembly, the bolts are often damaged. In this case, sufficient fastening cannot be performed. For this reason, as a general rule, it is impossible to use the bolt for this assembly for the temporary bolt. For this reason, it is necessary to perform an operation of replacing the temporary bolts with the main assembly bolts after assembling, and there is a problem that it takes time and effort.

そこで本発明は、上記問題点に鑑みて、接合する端部が開口した中空状の一対の柱部材の端部間を連結するために用いる接合部材が、その柱部材の外側に大きく突出することを容易に防止することができるような柱継手構造を提供することを課題とするものである。   Therefore, in view of the above problems, the present invention is such that the joining member used for connecting between the ends of a pair of hollow column members whose ends to be joined are greatly protruded to the outside of the pillar member. It is an object of the present invention to provide a column joint structure that can easily prevent this.
