It is characterized in that the opening end is exposed at the joint surface of the segment and is screwed into the embedded nut 2 for fastening.
Description
【０００１】[0001]
この考案は、セグメントの継手構造に関するものである。 The present invention relates to a joint structure for segments.
【０００２】[0002]
従来セグメントの継手構造として、接合すべきセグメント相互の接合面に相対 して箱抜きの継手ボックスを設け、相互の継手ボックスの接合板に設けたボルト 孔にボルトを通してナットで締結する構造のものが一般的に実施されている。 As a conventional joint structure for segments, a box-less joint box is provided facing the joint surfaces of the segments to be joined, and bolts are inserted through the bolt holes provided in the joint plates of the joint boxes to fasten them with nuts. It is commonly practiced.
【０００３】[0003]
上記従来の継手ボックスでは、接合すべきセグメントの双方の接合面に断面欠 損となる箱抜きが存在するため、セグメントの強度上の弱点ができると共に、組 立後に防錆の必要上継手ボックスの箱抜き部にモルタルを充填して穴詰め処理す る必要があり、その作業に手間と労力を要するなどの問題があった。 In the above-mentioned conventional joint box, since there is a box cutout that causes a cross-sectional loss on both joint surfaces of the segments to be joined, there are weak points in the strength of the segment, and rust prevention is required after assembly There was a problem that it was necessary to fill the mortar in the box removal part and fill the holes, which required labor and labor.
【０００４】 また、セグメントの組立時に片側の継手ボックスのボルト挿通孔にボルトを挿 通した後、他側の継手ボックスの箱抜き穴においてナットをねじ込んで締結する ため、作業が煩雑であるなどの問題があった。Further, since the bolts are inserted into the bolt insertion holes of the joint box on one side at the time of assembling the segment, the nuts are screwed and fastened in the box removal holes of the joint box on the other side, the work is complicated. There was a problem.
【０００５】[0005]
この考案は前記従来の課題を解決するために、一方のセグメント１の片側接合 面に埋設固定した継手板４に設けた挿通孔５にこの継手板４の後方に設けた箱抜 き部８からボルト９を挿通して、その先端を他方のセグメントの接合面に開口端 を表出して埋設したナット２にねじ込んで締結してなるセグメントの継手構造を 提案するものである。 In order to solve the above-mentioned conventional problems, this invention uses an insertion hole 5 provided in a joint plate 4 which is embedded and fixed in one joint surface of one segment 1 from a box removing portion 8 provided behind the joint plate 4. The joint structure of a segment is proposed in which the bolt 9 is inserted and the tip of the bolt is exposed at the joint surface of the other segment and screwed into the embedded nut 2 for fastening.
【０００６】[0006]
箱抜き部８がセグメント１の片側の接合面にだけ設けられているため、断面欠 損が少なく、組立後の穴詰処理も少なくて済む。 Since the box removing portion 8 is provided only on the joint surface on one side of the segment 1, the cross-section loss is small and the hole filling process after assembly is also small.
【０００７】 セグメント１の組立時に、箱抜き部８からボルト９を継手板４の挿通孔５に挿 通して、そのままその先端部を先行セグメントリングのセグメント１のナット２ にねじ込んで締結するため、締結作業が容易である。At the time of assembling the segment 1, the bolt 9 is inserted into the insertion hole 5 of the joint plate 4 from the box removal portion 8 and the tip portion is screwed into the nut 2 of the segment 1 of the preceding segment ring to be fastened. The fastening work is easy.
【０００８】[0008]
セグメント１の前後の接合面の一方には、ナット２がその開口端を表面に表出 して埋設され、その後端にはアンカー筋３がねじ込まれている。 A nut 2 is embedded in one of the front and rear joining surfaces of the segment 1 with its open end exposed on the surface, and an anchor bar 3 is screwed into the rear end thereof.
【０００９】 セグメント１の他方の接合面には、ナット２に対応する位置に継手板４が表面 を表出して埋設固定されている。On the other joint surface of the segment 1, a joint plate 4 is embedded and fixed at a position corresponding to the nut 2 so as to expose the surface.
【００１０】 継手板４には、ナット２の軸心位置に対応する位置に挿通すべきボルト径より も大きい挿通孔５が明けられている。The joint plate 4 has an insertion hole 5 larger than the diameter of the bolt to be inserted at a position corresponding to the axial center position of the nut 2.
【００１１】 また、継手板４にはその背面に左右に鋼製の側板６が直角に取付けられ、その 側板６の外面に後方に突出するアンカー筋７が固定され、継手板４の後方には箱 抜き部８が設けられている。Side plates 6 made of steel are attached to the rear surface of the joint plate 4 at right angles, and anchor ribs 7 projecting rearward are fixed to the outer surface of the side plate 6, and the rear side of the joint plate 4 is fixed. An unboxing section 8 is provided.
【００１２】 セグメント１の組立に際しては、組立てる各セグメント１を先に組立てた先行 セグメントリングに突き合わせ、箱抜き部８から継手板４の挿通孔５にボルト９ を挿通して、その先端部を先行セグメントリングのセグメント１のナット２にね じ込んで締結する。When assembling the segment 1, each segment 1 to be assembled is butted to the previously assembled preceding segment ring, and the bolt 9 is inserted from the box removing portion 8 into the insertion hole 5 of the joint plate 4, and the tip portion thereof is preceded. Tighten by screwing into the nut 2 of the segment 1 of the segment ring.
【００１３】 なお、リング方向に隣接するセグメント１，１は、コッター式継手金具で締結 すると、セグメント組立のさらなる自動化対応が可能となる。When the segments 1 and 1 adjacent to each other in the ring direction are fastened with a cotter-type joint fitting, the segment assembly can be further automated.
【００１４】[0014]
【考案の効果】 以上の通りこの考案によれば、箱抜き部がセグメントの片側の接合面にだけに 設けられているため、断面欠損が少なく、組立後の穴詰処理も少なくて済む。As described above, according to the present invention, since the box removing portion is provided only on the joint surface on one side of the segment, the cross-section loss is small and the hole filling process after assembly is also small.
【００１５】 セグメントの組立時に、箱抜き部からボルトを継手板の挿通孔に挿通して、そ の先端部を先行セグメントリングのセグメントのナットにねじ込んで締結するの で、締結作業が極めて容易である。At the time of assembling the segment, the bolt is inserted into the insertion hole of the joint plate from the box removal part, and the tip end is screwed into the nut of the segment of the preceding segment ring to be fastened, so that the fastening work is extremely easy. is there.
