Description

本発明は、デッキプレートと、これを補剛する閉断面リブとからなる鋼床版において、デッキプレートと閉断面リブとの接合部を、溶接によって補修する方法に関する。   The present invention relates to a method for repairing a joint portion between a deck plate and a closed cross-section rib by welding in a steel deck comprising a deck plate and a closed cross-section rib that stiffens the deck plate.

従来より、橋梁の床版構造の一つとして、デッキプレートと、これを補剛する閉断面リブとからなる鋼床版が使用されている。図１２は、このような鋼床版１の基本的な構造を示したものであって、本図において、２はデッキプレート、３は閉断面リブをなすＵリブ、４はデッキプレート２とＵリブ３との溶接による接合部を示している。また、図１３は、図１２の接合部４付近の拡大図であって、本図において、Ｊは溶接部を示している。   Conventionally, as one of the slab structures of a bridge, a steel slab comprising a deck plate and a closed cross-section rib that stiffens the deck plate has been used. FIG. 12 shows the basic structure of such a steel slab 1. In this figure, 2 is a deck plate, 3 is a U-rib forming a closed cross-section rib, 4 is a deck plate 2 and U The joint part by welding with the rib 3 is shown. FIG. 13 is an enlarged view of the vicinity of the joint 4 in FIG. 12. In this figure, J indicates a welded portion.

ところで、図１３に示したように、このような鋼床版１は、施工から相当の年数が経過すると、溶接部Ｊにおいて、亀裂Ｃが、Ｕリブ３の長手方向（図１３の紙面を垂直に貫通する方向）に沿って発生する場合があることが明らかになってきている。   By the way, as shown in FIG. 13, in such a steel floor slab 1, when a considerable number of years have passed since the construction, cracks C occur in the welded portion J in the longitudinal direction of the U rib 3 (perpendicular to the paper surface of FIG. 13). It has become clear that it may occur along the direction of the

このような亀裂Ｃを放置しておくと、溶接部Ｊが分断されて、Ｕリブ３がデッキプレート２から脱離し、鋼床版１全体の強度が低下してしまうという問題がある。また、最悪の場合、亀裂Ｃがデッキプレート２にまで達し、鋼床版１の崩壊（脆性破壊）を招いてしまうおそれもある。そのため、このような鋼床版１においては、亀裂Ｃの拡大を防止し、鋼床版１の強度を確保するための措置を採ることが必要とされている。   If such a crack C is left unattended, there is a problem that the welded portion J is divided, the U rib 3 is detached from the deck plate 2, and the strength of the entire steel deck 1 is lowered. In the worst case, the crack C may reach the deck plate 2 and may cause collapse (brittle fracture) of the steel deck 1. Therefore, in such a steel slab 1, it is necessary to take measures for preventing the crack C from expanding and ensuring the strength of the steel slab 1.

このような措置として、出願人においては、まず、Ｕリブ３の一部に作業孔（図示せず）をあけて、デッキプレート２とＵリブ３との間に、Ｕリブ３の内側（図１３においてＵリブ３の左側）から溶接用の開先を形成し、その後、この開先を新たに溶接する方法を検討した。図１４は、このような溶接を施した接合部４について示したものである。尚、本図において、Ｊ’は、新たに形成された溶接部を示している。   As such a measure, the applicant first opens a work hole (not shown) in a part of the U rib 3, and between the deck plate 2 and the U rib 3, the inside of the U rib 3 (see FIG. 13, a groove for welding was formed from the left side of the U-rib 3, and then a method for newly welding the groove was studied. FIG. 14 shows the joint 4 subjected to such welding. In this figure, J 'indicates a newly formed weld.

このような溶接を施すと、接合部４において、それまで溶接部Ｊだけに加わっていた力が、溶接部Ｊ’にも加わるようになるため、溶接部Ｊに加わっていた力が軽減され、亀裂Ｃの拡大防止を図ることができる。そのため、以上のような措置は、亀裂Ｃの拡大を防止し、鋼床版１の強度を確保するための措置として、有効なものであると考えられた。
特開２００１−４０７８２号公報 When such welding is performed, the force that has been applied only to the weld J until then in the joint 4 is also applied to the weld J ', so the force applied to the weld J is reduced, It is possible to prevent the crack C from expanding. Therefore, the measures as described above are considered to be effective as measures for preventing the expansion of the crack C and ensuring the strength of the steel deck 1.
JP 2001-40782 A

しかしながら、出願人においてさらなる検討を重ねた結果、以上の措置は、溶接作業を、Ｕリブ３の内側という閉断面リブ内の狭い空間の中で行う必要があり、溶接作業の効率が非常に悪いため、溶接の質の低下を招きやすく、鋼床版１の強度を確保するための措置としては問題があることが分かった。   However, as a result of further examination by the applicant, the above measures require that the welding work be performed in a narrow space inside the closed cross-section rib inside the U-rib 3, and the efficiency of the welding work is very poor. For this reason, it has been found that there is a problem as a measure for ensuring the strength of the steel deck 1 because the quality of welding is likely to be deteriorated.

また、以上の措置は、溶接の質の低下によって、デッキプレート２とＵリブ３との間に完全溶け込み溶接が行えず、未溶着部が残ってしまう場合もあるため、鋼床版１の強度を確保する上で問題があることも分かった。   In addition, the above measures may not allow complete penetration welding between the deck plate 2 and the U-rib 3 due to a decrease in the quality of welding, and an unwelded portion may remain. It was also found that there is a problem in securing.

本発明は、上記のような問題を回避しながら、デッキプレートと閉断面リブとの接合部を補修するためになされたものであって、補修しようとする接合部と、当該接合部に隣接している部分の閉断面リブの一部と、を除去することによって、前記接合部に隣接している部分のデッキプレートと、前記接合部に隣接している部分の前記閉断面リブとの間に、開先部を形成してから、溶接用の裏当て材を、前記開先部に閉断面リブの内側から固定した後、前記開先部を、前記閉断面リブの外側から溶接することを主たる特徴としている。   The present invention has been made to repair the joint portion between the deck plate and the closed cross-section rib while avoiding the above-described problems, and is adjacent to the joint portion to be repaired. By removing a portion of the closed cross-section rib of the portion between the deck plate of the portion adjacent to the joint portion and the closed cross-section rib of the portion adjacent to the joint portion. After forming the groove portion, fixing the welding backing material to the groove portion from the inside of the closed cross-section rib, and then welding the groove portion from the outside of the closed cross-section rib. The main feature.

本発明に係る補修方法は、デッキプレートと閉断面リブとの溶接を、閉断面リブの外側から行うので、閉断面リブの内側から溶接する場合と比べて、作業効率が非常によい。そのため、溶接の質を向上させることができる。   In the repair method according to the present invention, since the welding between the deck plate and the closed cross-section rib is performed from the outside of the closed cross-section rib, the working efficiency is very good as compared with the case of welding from the inside of the closed cross-section rib. Therefore, the quality of welding can be improved.

また、本発明に係る補修方法は、閉断面リブの外側において開先部を形成し、そこを溶接するようにしているので、デッキプレートと閉断面リブとの間に、未溶着部のない溶接（完全溶け込み溶接）を行うことができる。そのため、鋼床版において充分な強度を確保して、接合部を補修することができる。   Further, in the repair method according to the present invention, the groove portion is formed outside the closed cross-section rib and welded there, so that there is no unwelded portion between the deck plate and the closed cross-section rib. (Complete penetration welding) can be performed. Therefore, sufficient strength can be secured in the steel deck and the joint can be repaired.

さらに、本発明に係る補修方法は、開先部を形成する際に、デッキプレートと閉断面リブとの間の接合部を除去するので、当該補修方法の実施時において、デッキプレートの裏面を観察することができる。そのため、デッキプレートにまで亀裂が達している場合に、当該亀裂の発見及び状況の確認を行うことも可能である。   Furthermore, since the repair method according to the present invention removes the joint between the deck plate and the closed cross-section rib when forming the groove portion, the back surface of the deck plate is observed when the repair method is performed. can do. Therefore, when a crack has reached the deck plate, it is also possible to find the crack and confirm the situation.

以下、本発明を実施するための最良の形態について、図面を参照しながら説明する。図１は、本発明に係る補修方法を実施しようとする鋼床版１の一部を示したものである。尚、本図において、２はデッキプレート、３は閉断面リブをなすＵリブ、３ｓはＵリブ３の側壁、４はデッキプレート２とＵリブ３との溶接による接合部、また、Ｒは補修予定部（接合部４のうち、亀裂等のある補修しようとする部分）を示している。   The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 shows a part of a steel slab 1 to be subjected to a repair method according to the present invention. In this figure, 2 is a deck plate, 3 is a U-rib forming a closed cross-section rib, 3s is a side wall of the U-rib 3, 4 is a welded joint between the deck plate 2 and the U-rib 3, and R is a repair. A planned portion (a portion of the joint 4 to be repaired with a crack or the like) is shown.

本補修方法では、まず、図２に示したように、補修予定部Ｒの近くに位置しているＵリブ３の一部を切除して、作業口５をＵリブ３の下側に形成する。併せて、補修予定部Ｒの近くに位置しているＵリブ３の側壁３ｓに、複数の貫通孔６をあける。   In this repair method, first, as shown in FIG. 2, a part of the U rib 3 located near the repair planned portion R is cut off, and the working port 5 is formed below the U rib 3. . At the same time, a plurality of through holes 6 are formed in the side wall 3s of the U rib 3 located near the repair planned portion R.

次に、補修予定部Ｒと、この補修予定部Ｒに隣接している側壁３ｓとを切削加工によって除去し、補修予定部Ｒに隣接していたデッキプレート２と側壁３ｓとの間に、溶接用の開先部を形成する。図３は、補修予定部Ｒ付近の拡大断面図であって、以上のようにして形成した溶接用の開先部Ｅを示している。   Next, the planned repair portion R and the side wall 3s adjacent to the planned repair portion R are removed by cutting, and welding is performed between the deck plate 2 adjacent to the planned repair portion R and the side wall 3s. Forming a groove portion. FIG. 3 is an enlarged cross-sectional view in the vicinity of the repair planned portion R, and shows the groove portion E for welding formed as described above.

尚、このような開先部Ｅは、後で行う溶接加工が好適になされるようにするため、その開口幅Ｗは、デッキプレート２の厚さの１／３〜１／２となるように形成することが好ましく、また、その開口角度θは、４０°〜５０°の範囲となるように形成することが好ましい。   In addition, in order that the groove part E like this performs the welding process performed later suitably, the opening width W is set to be 1/3 to 1/2 of the thickness of the deck plate 2. Preferably, the opening angle θ is preferably in a range of 40 ° to 50 °.

開先部Ｅを形成したら、次は、図４に示したように、開先部ＥをＵリブ３の内側から塞ぐようにして、溶接用の裏当て材７を固定する。尚、ここで使用される裏当て材７は、作業口５からＵリブ３の内側へと入れられる。また、このような裏当て材７は、溶接後のビード形状を良くするため、開口幅Ｗの約２倍の直径を有するセラミック製のものを使用することが好ましい。   After forming the groove portion E, next, as shown in FIG. 4, the welding backing material 7 is fixed so as to close the groove portion E from the inside of the U rib 3. In addition, the backing material 7 used here is put into the inside of the U rib 3 from the work port 5. Moreover, in order to improve the bead shape after welding, it is preferable to use a ceramic material having a diameter about twice the opening width W.

裏当て材７を固定したら、Ｕリブ３の外側から開先部Ｅを溶接する。図５は、この溶接後における開先部Ｅを示したものである。本図において、Ｊ’は、再溶接によって形成された溶接部を表している。尚、裏当て材７は、開先部Ｅの溶接後に取り除く。   When the backing material 7 is fixed, the groove portion E is welded from the outside of the U rib 3. FIG. 5 shows the groove E after the welding. In this figure, J 'represents a weld formed by re-welding. The backing material 7 is removed after welding the groove portion E.

次に、図６に示したような補強部材１０を用意し、これを、図７に示したように、Ｕリブ３内へ入れてから、補強部材１０を、切除しなかったＵリブ３へと連結材８によって固定する。ここで、これら連結材８及び補強部材１０の固定は、ボルト９によって行い、このボルト９は、Ｕリブ３にあけられたボルト孔６（図２及び図６参照）に挿通する。   Next, the reinforcing member 10 as shown in FIG. 6 is prepared, and the reinforcing member 10 is put into the U-rib 3 as shown in FIG. And fixed by the connecting member 8. Here, the connecting member 8 and the reinforcing member 10 are fixed by a bolt 9, and the bolt 9 is inserted into a bolt hole 6 (see FIGS. 2 and 6) formed in the U rib 3.

尚、補強部材１０は、図６に示されているように、一対のプレート材１０ａと、プレート材１０ａの片面に取り付けられた板片１０ｂと、その板片１０ｂを両側から挟むようにしてプレート材１０ａ同士を接続するための一対の接続部材１０ｃとから構成されている。また、補強部材１０がＵリブ３内の側壁３ｓと好適に固定されるように、プレート材１０ａは、所定の傾きを有するように構成されている。   As shown in FIG. 6, the reinforcing member 10 includes a pair of plate materials 10a, a plate piece 10b attached to one side of the plate material 10a, and the plate material 10a sandwiching the plate piece 10b from both sides. It is comprised from a pair of connection member 10c for connecting each other. Further, the plate material 10a is configured to have a predetermined inclination so that the reinforcing member 10 is suitably fixed to the side wall 3s in the U-rib 3.

次に、本発明に係る補修方法の第二の実施形態について説明する。図８は、本実施形態に係る方法によって補修しようとする鋼床版１の一部を示したものである。尚、本図において、１１は鋼床版１の横リブを、また、１１ａは縦横リブ接合部（縦リブをなすＵリブ３と横リブ１１との接合部）を示している。本実施形態では、この横リブ１１が、補修予定部Ｒと交差するように存在している場合の補修方法について説明する。   Next, a second embodiment of the repair method according to the present invention will be described. FIG. 8 shows a part of the steel deck 1 to be repaired by the method according to the present embodiment. In this figure, 11 indicates a horizontal rib of the steel slab 1 and 11a indicates a vertical and horizontal rib joint (joint between the U rib 3 and the horizontal rib 11 forming the vertical rib). In the present embodiment, a repair method in the case where the lateral rib 11 exists so as to intersect with the repair planned portion R will be described.

まず、図９に示したように、横リブ１１から縦横リブ接合部１１ａを切除し、その後、第１の実施形態と同様に、補修予定部Ｒの近くに位置しているＵリブ３の一部を切除して、作業口５をＵリブ３の下側に形成する。併せて、補修予定部Ｒの近くに位置しているＵリブ３の側壁３ｓに、複数の貫通孔６をあける。   First, as shown in FIG. 9, the vertical and horizontal rib joint portion 11 a is cut from the horizontal rib 11, and then, as in the first embodiment, one of the U ribs 3 positioned near the planned repair portion R is obtained. The part is cut out and the working port 5 is formed below the U rib 3. At the same time, a plurality of through holes 6 are formed in the side wall 3s of the U rib 3 located near the repair planned portion R.

その後は、第一の実施形態と同様、図３〜図５に示したように、補修予定部Ｒにおける開先部Ｅの形成・溶接を行ってから、補強部材１０をＵリブ３内へ入れ、補強部材１０を、図１０に示したように、切除しなかったＵリブ３へと、連結材８及びボルト９によって一時的に固定する。その後、図１１に示したように、補強部材１０を、ブラケット１２を介して、ナット１３によって、切除しなかったＵリブ３及び横リブ１１に固定する。   Thereafter, as in the first embodiment, as shown in FIGS. 3 to 5, after forming and welding the groove portion E in the repair planned portion R, the reinforcing member 10 is inserted into the U rib 3. As shown in FIG. 10, the reinforcing member 10 is temporarily fixed to the U rib 3 that has not been cut by the connecting member 8 and the bolt 9. After that, as shown in FIG. 11, the reinforcing member 10 is fixed to the U rib 3 and the lateral rib 11 that have not been cut by the nut 13 via the bracket 12.

以上に説明したように、本発明に係る補修方法は、デッキプレート２とＵリブ３との溶接を、Ｕリブ３の外側から行うので、Ｕリブ３の内側から溶接する場合と比べて、作業効率が非常によい。そのため、溶接の質を向上させることができ、デッキプレート２とＵリブ３とを充分な強度をもって、接合させることができる。   As described above, in the repair method according to the present invention, the welding between the deck plate 2 and the U rib 3 is performed from the outside of the U rib 3. The efficiency is very good. Therefore, the quality of welding can be improved, and the deck plate 2 and the U rib 3 can be joined with sufficient strength.

また、本発明に係る補修方法は、Ｕリブ３の外側において開先部Ｅを形成し、そこを溶接するようにしているので、デッキプレート２とＵリブ３との間に、未溶着部のない溶接（完全溶け込み溶接）を容易に行うことができる。そのため、鋼床版１において充分な強度を確保して、接合部４を補修することができる。   Further, in the repair method according to the present invention, the groove portion E is formed on the outside of the U rib 3 and welded there, so that an unwelded portion is formed between the deck plate 2 and the U rib 3. No welding (complete penetration welding) can be performed easily. Therefore, sufficient strength can be secured in the steel deck 1 and the joint 4 can be repaired.

さらに、本発明に係る補修方法は、開先部Ｅを形成する際に、補修予定部Ｒを除去するので、補修方法の実施時において、デッキプレート２の裏面を見ることができる。そのため、デッキプレート２に亀裂が発生している場合に、当該亀裂の発見及び状況の確認を行うことができる。   Furthermore, since the repair method according to the present invention removes the repair planned portion R when forming the groove portion E, the back surface of the deck plate 2 can be seen when the repair method is performed. Therefore, when the deck plate 2 has a crack, the crack can be found and the situation can be confirmed.

尚、以上の各実施形態においては、鋼床版１の閉断面リブが、Ｕリブ３となっているが、当然ながら、本発明に係る補修方法は、Ｕリブから構成される鋼床版だけでなく、Ｙリブなど、その他の閉断面リブから構成される鋼床版にも適用することが可能である。   In each of the above embodiments, the closed cross-section rib of the steel deck 1 is the U-rib 3, but naturally, the repair method according to the present invention is only a steel deck comprised of U-ribs. In addition, the present invention can be applied to steel slabs composed of other closed cross-section ribs such as Y ribs.
