Description
【０００１】[0001]
本考案はＣ形鋼材の連結構造に関し、より詳細には、各種の建築構造物の鉄骨 資材として利用されるＣ形鋼材の連結構造に関する。 The present invention relates to a connection structure of C-shaped steel materials, and more particularly, to a connection structure of C-shaped steel materials used as steel materials of various building structures.
【０００２】[0002]
従来、２つの被連結部材を連結し、少なくとも一方の被連結部材がＣ形鋼材で あるＣ形鋼材の連結構造には、図１２に示すような構造が採用されていた。 図１２に示した従来技術では、Ｃ形鋼材１と連結される被連結部材２に固定さ れる固定片４と、固定片４から略垂直方向に立ち上がって形成された取付片５と からなる連結部材３に、Ｃ形鋼材１の背面部を当接させ、Ｃ形鋼材１に穿設され たボルト挿通孔６と取付片５に穿設されたボルト挿通孔７とにボルト８を挿通さ せ、ナット９を締め込ませることにより、Ｃ形鋼材１と被連結部材２とを連結さ せていた。 Conventionally, a structure as shown in FIG. 12 has been adopted as a connection structure of a C-shaped steel material in which two connected members are connected and at least one of the connected members is a C-shaped steel material. In the prior art shown in FIG. 12, a connection comprising a fixing piece 4 fixed to a connected member 2 connected to a C-shaped steel material 1 and a mounting piece 5 formed to stand substantially vertically from the fixing piece 4. The back surface of the C-shaped steel member 1 is brought into contact with the member 3, and the bolt 8 is inserted into the bolt insertion hole 6 formed in the C-shaped steel member 1 and the bolt insertion hole 7 formed in the mounting piece 5. Then, the nut 9 is tightened to connect the C-shaped steel member 1 and the connected member 2.
【０００３】 しかしながら上記従来技術では、ボルト８を挿通するためのボルト挿通孔６を 予め工場等でＣ形鋼材１に穿設しておく必要があり、この穿設作業が面倒であっ た。 特に、Ｃ形鋼材１が長尺の場合には、穿設作業が非常に面倒であった。 また、上記したように予めボルト挿通孔６を工場等で穿設するようになってい ると、ボルト挿通孔６の位置決め、現場での位置合わせが難しく、Ｃ形鋼材１の 連結位置を微調整することは困難であった。 従って、従来ではボルト挿通孔６の穿設位置が不正確な場合はもちろんのこと 、前記穿設位置が正確な場合であったとしても、例えば被連結部材２や連結部材 ３の配設位置が変更されるなどの各部の仕様に変更がなされると、Ｃ形鋼材１と 被連結部材２とを適切に連結させることは極めて困難であった。However, in the above-mentioned conventional technique, it is necessary to previously drill the bolt insertion hole 6 for inserting the bolt 8 in the C-shaped steel material 1 at a factory or the like, and this drilling operation is troublesome. In particular, when the C-shaped steel material 1 is long, the drilling operation is very troublesome. Further, if the bolt insertion holes 6 are previously drilled in a factory or the like as described above, it is difficult to position the bolt insertion holes 6 and to perform on-site positioning, and finely adjust the connection position of the C-shaped steel material 1. It was difficult to do. Therefore, conventionally, not only when the drilling position of the bolt insertion hole 6 is inaccurate but also when the drilling position is accurate, for example, the arrangement positions of the connected member 2 and the connecting member 3 are changed. If the specification of each part is changed, for example, it is changed, it is extremely difficult to properly connect the C-shaped steel member 1 and the connected member 2.
【０００４】 そこで種々のＣ形鋼材の連結構造技術が開発されてきた。 例えば、実開平５−２４７０９号公報（以下、公知例１と記す）に開示された 技術は、Ｃ形鋼材にて形成される母屋や胴縁のような横架材を合掌や柱のような 取付基材（本願請求項における被連結部材に相当）と直交するように配設させ、 前記取付基材の外面より側方に突設された支持片（本願請求項における取付片に 相当）に前記横架材を載設させ、前記横架材の一側面開口を前記支持片に向けて 対向させると共に開口縁に設けられた対向するリップ片を前記支持片上に載置さ せ、前記支持片より突設された連結ボルトに螺着された押さえ板（本願請求項に おける締付板に相当）を前記横架材内に収納配置させている。[0004] Therefore, various connection structure technologies for C-shaped steel materials have been developed. For example, the technology disclosed in Japanese Utility Model Laid-Open Publication No. Hei 5-24709 (hereinafter referred to as Known Example 1) discloses a method in which a horizontal member such as a purlin or a rim formed of a C-shaped steel material is used as a joint or a pillar. A support piece (corresponding to a mounting piece in the present application) is disposed so as to be orthogonal to a mounting base material (corresponding to a connected member in the present application), and protrudes laterally from an outer surface of the mounting base. The horizontal member is placed, one side opening of the horizontal member is opposed to the support piece, and an opposing lip provided at an opening edge is placed on the support piece, and the support piece is provided. A holding plate (corresponding to a fastening plate in the claims of the present application) screwed to a connecting bolt that is more protruded is housed and arranged in the horizontal member.
【０００５】 このように構成することによって、合掌（又は柱）とＣ形鋼材にて形成される 母屋（又は胴縁）とを連結する連結構造であり、前記Ｃ形鋼材を前記支持片に載 置させる構造の場合には、ボルトを挿通するためのボルト挿通孔を予め工場等で Ｃ形鋼材に穿設する必要をなくすことができ、作業効率の向上と共にＣ形鋼材の 連結位置の微調整を容易に行なうことを可能とする。[0005] With this configuration, the joint structure (or pillar) and the purlin (or trunk edge) formed of a C-shaped steel material are connected to each other, and the C-shaped steel material is mounted on the support piece. In the case of a structure where the bolts are inserted, it is not necessary to previously drill bolt insertion holes for inserting bolts in a C-shaped steel material at a factory or the like, which improves work efficiency and fine-tunes the connection position of the C-shaped steel material. Can be easily performed.
【０００６】[0006]
しかしながら公知例１に開示された技術は、合掌（又は柱）とＣ形鋼材にて形 成される母屋（又は胴縁）とを連結する連結構造であり、前記Ｃ形鋼材を前記支 持片に載置させる構造の場合にだけ、上記効果を発揮するものであり、前記場合 以外、例えば、Ｃ形鋼材の一側面開口を地面に向けずに、前記Ｃ形鋼材と被連結 部材とを連結させるといった場合には、上記効果を発揮することができない。 However, the technique disclosed in the publicly known example 1 is a connecting structure for connecting a joint palm (or a pillar) and a purlin (or a rim) formed of a C-shaped steel material, and the C-shaped steel material is connected to the supporting piece. The above-described effect is exhibited only in the case of a structure in which the C-shaped steel material is connected to the member to be connected, without facing one side opening of the C-shaped steel material to the ground. In such a case, the above effect cannot be exhibited.
【０００７】 その他、従来では、２つのＣ形鋼材を連結する場合には、これらＣ形鋼材どう しの溶接を施すなどの煩雑な手段が採用され、高所での作業が多いことからその 連結作業が困難となって作業効率を下げていたが、その問題を解決するために、 例えば、特開平８−４２００２号公報（以下、公知例２と記す）に以下に記す技 術が開示されている。[0007] In addition, conventionally, when connecting two C-shaped steel materials, complicated means such as welding of these C-shaped steel materials are employed, and the connection is often performed at high places. The work efficiency has been reduced due to the difficulty of the work. To solve the problem, for example, the technology described below is disclosed in JP-A-8-42002 (hereinafter referred to as known example 2). I have.
【０００８】 公知例２に開示された技術は、各Ｃ形鋼材のリップ片を連結用板（本願請求項 における連結部材に相当）と、当て板（本願請求項における締付板に相当）と、 ボルト・ナットとで狭持する構造となっている。 このように構成することによって、２つのＣ形鋼材を連結する場合に、これら Ｃ形鋼材どうしを溶接することや、各Ｃ形鋼材にボルト挿通孔を穿設することの 必要がなくなると共に、Ｃ形鋼材の連結位置の微調整を容易に行なうことが可能 となる。[0008] The technique disclosed in the second prior art discloses a technique in which a lip piece of each C-shaped steel material is connected to a connecting plate (corresponding to a connecting member in the claims of the present application) and a backing plate (corresponding to a fastening plate in the claims of the present application). , It is structured to be held between bolts and nuts. With this configuration, when connecting two C-shaped steel materials, it is not necessary to weld these C-shaped steel materials or to form a bolt insertion hole in each of the C-shaped steel materials. Fine adjustment of the connection position of the shaped steel material can be easily performed.
【０００９】 しかしながら公知例２に開示された技術では、現場取り付け時に作業員がボル トとナットとを連結位置まで持っていき組み込んだ後に、締め付け作業を行なわ なければならず、この締め付け作業は簡単ではなく、作業が煩雑になるといった 問題がある。 本考案は上記課題に鑑みなされたものであって、Ｃ形鋼材の向き、及び連結位 置に関わらず、前記Ｃ形鋼材の連結作業を容易に行なうことができるＣ形鋼材の 連結構造を提供することを目的としている。However, according to the technique disclosed in the prior art 2, when the worker attaches the bolt and the nut to the connecting position at the time of installation on the site, the worker has to perform the tightening work, and this tightening work is simple. However, there is a problem that the work becomes complicated. The present invention has been made in view of the above problems, and provides a connection structure of C-shaped steel materials that can easily perform the connection work of the C-shaped steel materials regardless of the orientation and the connection position of the C-shaped steel materials. It is intended to be.

上記目的を達成するために本考案に係るＣ形鋼材の連結構造（１）は、２つの 被連結部材を連結し、少なくとも一方の被連結部材がＣ形鋼材であるＣ形鋼材の 連結構造において、 他方の被連結部材に固定される固定片と、該固定片から略垂直方向に立ち上が り、中央部にはボルト挿通孔を有し、一端中央部には前記Ｃ形鋼材側に突出して 前記Ｃ形鋼材のリップ片が引っ掛けられる引掛片が形成された取付片とからなる 連結部材と、 ねじ孔を有し、前記Ｃ形鋼材のリップ片を前記取付片との間で狭持する締付板 と、 前記Ｃ形鋼材のリップ片を前記締付板と前記取付片との間で締め付けるボルト とを含んで構成されていることを特徴としている。 In order to achieve the above object, a connecting structure of a C-shaped steel material according to the present invention (1) connects two connected members and at least one of the connected members is a C-shaped steel material. A fixing piece fixed to the other member to be connected, and rising from the fixing piece in a substantially vertical direction, having a bolt insertion hole at the center, and projecting toward the C-shaped steel material at one end center.

The C-shaped steel material is attached to the connecting member by hooking the lip piece of the above, performing a fastening operation with the bolt, and holding the lip piece of the C-shaped steel material between the fastening plate and the mounting piece. The C-shaped steel member and the connected member can be connected. In addition, by hooking the lip piece of the C-shaped steel material on the hooking piece and supporting the C-shaped steel material on the connecting member, the tightening operation becomes extremely easy. In addition, the hook piece not only facilitates the tightening operation, but also supports the C-shaped steel material to improve the strength of the connection. Therefore, regardless of the direction and the connection position of the C-shaped steel material, a strong connection between the C-shaped steel material and the member to be connected is enabled.

By sandwiching the lip piece of the C-shaped steel material, the C-shaped steel material can be attached to the connecting member to connect the two C-shaped steel materials. In addition, by hooking the lip piece of the C-shaped steel material on the hooking piece and supporting the C-shaped steel material on the connecting member, the tightening operation becomes extremely easy.

It is suitable for constructing a steel structure in which a large number of C-shaped steel materials are arranged vertically and horizontally. Further, the connecting position between the C-shaped steel materials can be easily adjusted.

The fixing piece 14 is fixed to the connected member 12. Further, the lip pieces 21 and 22 of the C-shaped steel material 11 are fastened between the fastening piece 18 and the mounting piece 15 by the bolt 20.
【００３４】 上記実施の形態（１）に係るＣ形鋼材の連結構造によれば、固定片１４を被連 結部材１２に固定させることで被連結部材１２に連結部材１３を取り付けると共 に、引掛片１６にＣ形鋼材１１のリップ片２１を引っ掛け、ボルト２０で締め付 け作業を行ない、締付板１８と取付片１５とでＣ形鋼材１１のリップ片２１、２ ２を狭持することによって、連結部材１３にＣ形鋼材１１を取り付け、Ｃ形鋼材 １１と被連結部材１２とを連結させることができる。 また、引掛片１６にＣ形鋼材１１のリップ片２１を引っ掛け、連結部材１３に Ｃ形鋼材１１を支持させておくことにより、前記締め付け作業が極めて容易とな る。 また、引掛片１６は前記締め付け作業を容易にするだけでなく、Ｃ形鋼材１１ を支持して連結の強度を向上させることができる。従って、Ｃ形鋼材１１の向き 、及び連結位置に関わらず、Ｃ形鋼材１１と被連結部材１２との強固な連結を可 能とする。According to the connecting structure of the C-shaped steel material according to the above-mentioned embodiment (1), the fixing member 14 is fixed to the connected member 12 so that the connecting member 13 is attached to the connected member 12 and The lip piece 21 of the C-shaped steel material 11 is hooked on the hook piece 16 and tightened with a bolt 20, and the lip pieces 21 and 22 of the C-shaped steel material 11 are held between the fastening plate 18 and the mounting piece 15.
