【０００１】[0001]
本考案は、円筒型継手を有する鋼管矢板の胴継ぎ手部分における継手構造に関 するものである。 The present invention relates to a joint structure in a body joint portion of a steel pipe sheet pile having a cylindrical joint.
【０００２】[0002]
一般に、建造物地下部分の構築にあたっては、土留壁を施設するが、この土留 壁工法の一つとして、鋼管矢板を柱列状に連結して形成する鋼管柱列土留壁工法 がある。この土留壁に使用される鋼管矢板は、例えば、実公昭63-38285号公報の 第１図、第２図に示されているように、鋼管の一例にＯ型の継手、他側にＣ型の 継手を溶接により固着しており、各鋼管は互いにそれらの継手を係合して連結さ れるのである。 Generally, when constructing an underground part of a building, a retaining wall is installed. One of the retaining wall construction methods is the steel column post retaining tube construction method in which steel pipe sheet piles are connected in a column shape. The steel pipe sheet pile used for this retaining wall is, for example, as shown in FIGS. 1 and 2 of Japanese Utility Model Publication No. Sho 63-38285, an O-type joint as an example of the steel pipe and a C-type as the other side. The joints are fixed by welding, and the steel pipes are connected to each other by engaging their joints.
【０００３】 また、上記の鋼管矢板は、施工仕様により、縦方向に複数本を継ぎ合せ（胴継 ぎ）ながら打設することが行なわれる。この胴継ぎにおいては、矢板本管同志の 溶接結合の際に継手部分がじゃまになることから、従来、図７に示すように、Ｏ 型継手３及びＣ型継手４を、矢板本管２の両端より相当の距離内方で終る長さに した鋼管矢板１を用い、矢板本管２，２を溶接結合５した後、継手３，４の欠徐 部分６，６に図８に示すように、それらの継手３，４と同形の連結継手７，８を 挿入して溶接９，９により固着するようにしている。In addition, the above-mentioned steel pipe sheet pile is laid according to the construction specifications while splicing a plurality of pieces in a vertical direction (joining with a cylinder). In this body joint, since the joint portion becomes a hindrance when welding the sheet pile main pipes together, conventionally, as shown in FIG. 7, the O type joint 3 and the C type joint 4 are connected to the sheet pile main pipe 2. After using steel pipe sheet pile 1 having a length that ends a considerable distance inward from both ends and welding sheet pipe main pipes 2 and 2 by welding 5, as shown in FIG. , Connection joints 7 and 8 having the same shape as those joints 3 and 4 are inserted and fixed by welding 9 and 9.
【０００４】 上記の胴継ぎは、すべてが現場での溶接作業で行なわれており、そのため、鋼 管矢板の胴継ぎ工程には多くの時間を要しており、また溶接工不足の問題も深刻 化していることから、その改善が求められていた。[0004] All of the above piecing joints are carried out by welding work at the site, so that it takes a lot of time for the piecing joint of steel pipe sheet piles, and the problem of shortage of welders is serious. Since it is becoming more and more popular, its improvement has been demanded.
【０００５】 本考案は、このような胴継ぎにおける問題を解決し、溶接を最小限で抑え、熟 練を要さず、簡単な作業で短時間に胴継ぎのできるようにした継手装置を提供し ようとするものである。The present invention solves such a problem in the piecing joint, and provides a joint device which can minimize the welding, does not require aging, and can perform the piecing joint in a short time by a simple operation. It is the one to try.

Then, this steel pipe sheet pile 1 is joined to another steel pipe sheet pile 1 at the ends of the sheet pile main pipes 2 and 2 and fixed (welded) by welding 5 as shown in FIG. As a result, a notch 6 having a considerable length is formed between the ends of the O-shaped joints 3 and 3 of the steel pipe sheet piles 1 and 1.
【００１０】 11は、上記欠除部６に挿嵌する連結継手で、図３に示すように、Ｏ型継手３と ほぼ同様の横断面形をなし、欠除部６の長さとほぼ同長に形成された継手本体12 と、その中に、継手本体12の軸方向に移動自在に挿入された一対の係合部材13と により構成されており、継手部材12にはその軸線に沿ったスリット14が設けられ ている。なお、図の実施例において、スリット14は継手本体12の全長にわたって 設けられているが、継手本体12の一部の長さであってもよい。また、係合部材13 は管体となっているが、これも例えば半管状のものとすることもできる。Reference numeral 11 denotes a coupling joint that is fitted into the cutout portion 6 and has a transverse cross section similar to that of the O-type joint 3 as shown in FIG. 3 and has a length substantially the same as the length of the cutout portion 6. And a pair of engaging members 13 inserted in the joint body 12 so as to be movable in the axial direction of the joint body 12, and the joint member 12 has slits along its axis. 14 are provided. Although the slit 14 is provided over the entire length of the joint body 12 in the illustrated embodiment, it may be part of the joint body 12. Further, although the engaging member 13 is a tubular body, it may be a semi-tubular one, for example.
【００１１】 上記の連結継手11は、図２に示すように、係合部材13, 13を継手本体12中に納 めた状態で欠除部６に挿嵌され、図11に示すように、スリット14に棒材等（図示 を略す）を差入れて係合部材13，13を外方に移動させ、その先端部を矢板本管２ に固着されているＯ型継手３，３内にそれぞれ突入させる。その際、硬化時間の 短い、例えばアクリル系あるいはエポキシ系の接着剤を使用して、矢板本管２， ２及びＯ型継手３，３に接着結合15，15するのである。また、この場合、スリッ ト中に接着剤を注入して継手本体11自体の補強と係合部材を固定してやれば一層 効果的となる。As shown in FIG. 2, the coupling joint 11 is inserted into the notch 6 with the engaging members 13, 13 accommodated in the joint body 12, and as shown in FIG. A rod or the like (not shown) is inserted into the slit 14 to move the engaging members 13 and 13 outwardly, and the tips of the engaging members 13 and 13 are respectively inserted into the O-type joints 3 and 3 fixed to the sheet pile main pipe 2. Let At this time, an adhesive agent having a short curing time, for example, an acrylic adhesive agent or an epoxy adhesive agent is used to adhesively bond 15, 15 to the sheet pile main pipes 2, 2 and the O type joints 3, 3. Further, in this case, it is more effective if the adhesive is injected into the slit to reinforce the joint body 11 itself and fix the engaging member.
【００１２】 次に、図４〜図６において、２は矢板本管、４は雌継手である円筒状のＣ型継 手で、図１〜図３の例と同様に、溶接５により胴継ぎされた２本の矢板本管２， ２のＣ型継手４，４間には、図５に示すように欠除部６が形成される。16は上記 欠除部６に挿嵌する連結継手で、図６に示すように、Ｃ型継手４とほぼ同様の横 断面形をなし、欠除部６の長さとほぼ同長に形成された継手本体17と、その両端 部の外側面に、係着板18, 18がそれぞれ継手本体17より軸方向外方に突出して、 溶接あるいは接着剤により固着されている。Next, in FIGS. 4 to 6, 2 is a sheet pile main pipe, 4 is a cylindrical C-shaped joint which is a female joint, and as in the example of FIGS. As shown in FIG. 5, a cutout portion 6 is formed between the C-shaped joints 4 and 4 of the cut two sheet pile main pipes 2 and 2. Reference numeral 16 denotes a connecting joint which is fitted into the cutout portion 6 and has a cross sectional shape similar to that of the C-type joint 4 as shown in FIG. 6, and is formed to have substantially the same length as the length of the cutout portion 6. Engagement plates 18, 18 project axially outward from the joint body 17 and are fixed to the joint body 17 and the outer surfaces of both ends thereof by welding or an adhesive.
【００１３】 上記の連結継手16は、図５、図４に示すように、欠除部６に挿嵌され、その係 着板18, 18の突出した部分をＣ型継手４，４の外面に添接する。その際、継手本 体17と矢板本管２，２及びＣ型継手４，４とを、また、係着板18，18とＣ型継手 ４，４とを接着剤によって接着結合15，15するのである。As shown in FIGS. 5 and 4, the coupling joint 16 is inserted into the cutout portion 6, and the protruding portions of the fastening plates 18, 18 are attached to the outer surfaces of the C-shaped joints 4, 4. Counsel. At that time, the joint main body 17 and the sheet pile main pipes 2 and 2 and the C-shaped joints 4 and 4, and the fastening plates 18 and 18 and the C-shaped joints 4 and 4 are adhesively bonded 15 and 15 with an adhesive. Of.

以上説明したように、本考案の継手構造によれば、雄継手であるＯ型継手及び 雌継手であるＣ型継手の欠除部への連結継手の固着作業が、溶接手段によらず、 機械的な組み合せと接着剤とにより行なわれるので、従来のような溶接に比べて 簡便で熟練を要さずにでき、鋼管矢板の胴継ぎの施工時間の短縮と経済性の向上 が図れる。 As described above, according to the joint structure of the present invention, the work of fixing the connecting joint to the notches of the O-type joint which is the male joint and the C-type joint which is the female joint does not depend on the welding means. As compared with conventional welding, it can be performed more easily and does not require skill, since it is performed with a special combination and an adhesive, and the construction time of steel pipe sheet pile joints can be shortened and economic efficiency can be improved.
【００１５】 そして、Ｏ型継手と連結継手とは係合部材による嵌め合せもなされ、また、Ｃ 型継手と連結継手とは係着板による面結合もなされるので、機械的な結合強度は 従来の溶接によるものと同等のものが確保できる。Since the O-type joint and the coupling joint are fitted together by the engaging members, and the C-type joint and the coupling joint are also surface-joined by the engaging plate, the mechanical coupling strength is not so high. It is possible to secure the same thing as by welding.
