（考案が属する技術分野）
本考案は、トンネル工事等で使用される支保工
材の継ぎ手に関するものである。[Detailed description of the invention] (Technical field to which the invention belongs) The present invention relates to a joint for shoring materials used in tunnel construction, etc.
（考案の課題とその特徴点）
従来の支保工材の継ぎ手は、通常、支保工材の
端面に接続板を取り付け、隣接の支保工材の接続
板相互をボルトで連結して構成されているが、こ
のようなボルトによる接続は、孔合わせやナツト
締めに時間を要し、非能率的である。(Issues of the invention and its features) Conventional shoring material joints are usually constructed by attaching connecting plates to the end faces of the shoring materials and connecting the connecting plates of adjacent shoring materials with each other with bolts. However, such connections using bolts are inefficient as it takes time to align holes and tighten nuts.
本考案は、前記実情に鑑み、接続作業にあまり
時間を要しない支保工材の継ぎ手を提供すること
を目的としているものであつて、本考案の支保工
材の継ぎ手の特徴は、Ｉ形鋼もしくはＨ形鋼から
成る支保工材の両端部のウエブの両側面に、上下
のフランジの裏面との間にそれぞれ小間隙をあ
け、かつ、略平行に、比較的短い板材を取り付
け、隣接の支保工材の対応する小間隙をそれぞれ
連通させて、この連通した小間隙にコツタを差し
込んで成る点にある。 In view of the above-mentioned circumstances, the purpose of the present invention is to provide a joint for shoring materials that does not require much time for connection work. Alternatively, attach relatively short plates approximately parallel to both sides of the web at both ends of the shoring material made of H-beams, with a small gap between them and the back surfaces of the upper and lower flanges. The point is that the corresponding small gaps in the work materials are communicated with each other, and the kotsuta is inserted into the connected small gaps.
（考案の具体的説明）
図示の支保工材１は、円形の支保工用で、弧状
に湾曲しており、その断面形状はＩ形である。(Specific description of the invention) The illustrated shoring material 1 is for circular shoring, is curved in an arc shape, and has an I-shaped cross section.
２は支保工材１の両端部のウエブ３の両側面に
予め取り付けておく比較的短い板材であり、その
取り付け位置は上下のフランジ４，４の近くで、
各フランジ４の裏面からそれぞれ小間隙５をあ
け、かつ、各フランジ４と略平行に取り付けられ
る（第１図，第２図のイ参照）。 Reference numeral 2 denotes a relatively short plate material that is attached in advance to both sides of the web 3 at both ends of the shoring material 1, and its attachment position is near the upper and lower flanges 4, 4.
A small gap 5 is provided from the back surface of each flange 4, and the flange 4 is attached substantially parallel to each flange 4 (see A in FIGS. 1 and 2).
第２図のロの２′前記板材の変形例を示してお
り、この板材２′はひれ付きで、ひれ６で小間隙
５の側方を閉じるようになつている。 FIG. 2B shows a modification of the plate 2', which is provided with fins so that the sides of the small gap 5 are closed by the fins 6.
支保工材１の継ぎ手７は、現場において隣接の
支保工材１，１の端面相互を当接し、対応する小
間隙５，５を連通状態にして、この連通した小間
隙５，５にコツタ８を前方もしくは側方から差し
込んで構成される（第３図、第４図参照）。 The joint 7 of the shoring material 1 abuts the end surfaces of the adjacent shoring materials 1, 1 at the site, brings the corresponding small gaps 5, 5 into communication, and connects the joint 8 to the small gaps 5, 5 that communicate with each other. It is constructed by inserting it from the front or side (see Figures 3 and 4).
この際、支保工材１，１間に微小なずれがあつ
ても、コツタ８を軽く打ち込むことで容易にこれ
を是正することができ、そして、以上のようにし
て構成された継ぎ手７は力学的に十分な耐力性が
ある。 At this time, even if there is a slight misalignment between the shoring materials 1 and 1, this can be easily corrected by lightly driving the kotsuta 8, and the joint 7 constructed as described above is mechanically It has sufficient strength.
（考案の効果）
本考案の支保工材の継ぎ手は、以上のようなも
のであるから、現場における支保工材の接続作業
が簡単かつ容易で、短時間で済み、能率的である
という効果が期待できる。(Effects of the invention) Since the shoring material joint of the present invention is as described above, it has the effect that the work of connecting shoring materials on site is simple, easy, takes a short time, and is efficient. You can expect it.
