Description

本発明は、構造物を組み立てる時、部材を構成する鋼板同士を突合せ溶接等する接合部において、その継ぎ目に目違いが生じている場合に、当該目違いを修正する、板材継ぎ目の目違い修正治具に関する。 INDUSTRIAL APPLICABILITY The present invention corrects a seam difference in a joint portion where steel plates constituting a member are butt-welded to each other when assembling a structure, and corrects the seam difference. Regarding jigs.

例えば、建物の屋根等に用いられる鉄骨造単層トラス架構において、図１および２に図示のように、トラス部材にＣＴ形断面部材を用いることがあった。図１は、トラス部材１０１、１０１、…が１つの節点部材１００に集合して成る節点部の１例を示した伏図である。 For example, in a steel-framed single-layer truss frame used for a roof of a building or the like, a CT-shaped cross-sectional member may be used as the truss member as shown in FIGS. 1 and 2. FIG. 1 is a plan showing an example of a node portion in which truss members 101, 101, ... Are aggregated in one node member 100.

節点部材１００は、集合するトラス部材１０１、１０１、…を接合するためのブラケット１００a、１００a、…を有する。図１のイ－イ断面視である図２に図示のように、各ブラケット１００a、１００a、…は接合される部材に応じた角度で節点部材１００、１００、…に取付いている。 The node member 100 has brackets 100a, 100a, ... For joining the truss members 101, 101, ... To be assembled. As shown in FIG. 2, which is a cross-sectional view of the eye of FIG. 1, the brackets 100a, 100a, ... Are attached to the nodal members 100, 100, ... At an angle corresponding to the member to be joined.

建設現場において、トラス部材１０１、１０１、…とブラケット１００a、１００a、…とを接合する方法として、図２（ａ）に図示のように、板材継ぎ目１０２を現場溶接する方法と、図２（ｂ）に図示のように、フランジ接合板１０３、１０３、…とウェブ接合板１０４、１０４、…によりボルト接合する方法が代表的であった。 As a method of joining the truss members 101, 101, ... And the brackets 100a, 100a, ... At the construction site, as shown in FIG. 2A, a method of on-site welding of the plate material seam 102 and FIG. 2 (b). ), As shown in the figure, a method of bolt-joining the flange joint plates 103, 103, ... And the web joint plates 104, 104, ... Was typical.

現場施工の面では、図２（ｂ）に図示の方法が効率的であるが、フランジ接合板１０３、１０３、…とウェブ接合板１０４、１０４、…が視認されるので、意匠性の観点から図２（ａ）に図示の溶接工法が採用されることがあった。 In terms of on-site construction, the method shown in FIG. 2B is efficient, but since the flange joint plates 103, 103, ... And the web joint plates 104, 104, ... Are visually recognized, from the viewpoint of designability. The welding method shown in FIG. 2A may be adopted.

図２（ａ）に図示のように、ウェブ部分の板材継ぎ目１０２を現場溶接する場合、次のような問題があった。即ち、Ｈ形鋼のように上下にフランジがある部材同士の板材継ぎ目であれば、ウェブの目違いはフランジの継ぎ目の精度が良ければ問題になり難いが、ＣＴ形断面部材の、特に溶接組立て部材のウェブの自由端（フランジが無い）側は、溶接熱影響の残留ひずみ等によって、フランジの継ぎ目に目違いがなくてもウェブ面外に反っていることがあり、現場での溶接に際しては、例えば、エレクションピースを設ける、あるいはアングルピースを溶接して楔を打ち込んで目違いを修正する等の方法が用いられていた。 As shown in FIG. 2A, when the plate material seam 102 of the web portion is welded in-situ, there are the following problems. That is, in the case of plate joints between members having flanges at the top and bottom, such as H-shaped steel, the difference in web mesh is unlikely to be a problem if the accuracy of the flange joints is good, but CT-shaped cross-section members, especially welded assembly. The free end (without flange) side of the web of the member may be warped outside the web surface even if there is no difference in the seam of the flange due to residual strain due to welding heat, etc. For example, a method of providing an erection piece or welding an angle piece and driving a wedge to correct a misalignment has been used.

これら従来方法の場合、目違い修正用のエレクションピース等の溶接および溶接完了後の切除や溶接部のグラインダー仕上げが必要なので、手間がかかる上に、エレクションピースの切断痕等が残り見栄えが良くないという問題があった。 In the case of these conventional methods, it is necessary to weld the erection piece for correcting the misalignment, cut off after the welding is completed, and grind the welded part. There was a problem.

板材の継ぎ目に生じた目違いを現場にて修正する技術に関しては、例えば特許文献１記載の発明が開示されている。この特許文献１記載の発明は、相対向する形鋼フランジの一方のフランジ面に対して垂直に支持される鈎状の垂直固定部と、該垂直固定部の下位に連設されて前記形鋼フランジに平行に配設される水平基部と、該水平基部に螺合されて前記形鋼フランジの下面に当接される間隔調整部とを備え、かつ、前記水平基部は前記形鋼フランジに対向する他方の形鋼フランジの下面まで延出しており、前記水平基部に支持されて前記他方の形鋼フランジの下面との間に小型ジャッキからなる変位可動部を有する、目違い修正治具である。 For example, the invention described in Patent Document 1 is disclosed as a technique for correcting a misalignment occurring at a seam of a plate material in the field. The invention described in Patent Document 1 has a flange-shaped vertical fixing portion that is vertically supported with respect to one flange surface of the opposing shaped steel flanges, and the shaped steel that is continuously provided below the vertical fixing portion. It is provided with a horizontal base portion arranged parallel to the flange and an interval adjusting portion screwed to the horizontal base portion and brought into contact with the lower surface of the shaped steel flange, and the horizontal base portion faces the shaped steel flange. It is a misalignment correction jig that extends to the lower surface of the other shaped steel flange and has a displacement movable portion formed of a small jack between the horizontal base and the lower surface of the other shaped steel flange. ..

特許文献１記載の発明は、このような構成であるので、目違いを修正する場合、相対向する形鋼フランジの一方を前記垂直固定部の鈎状部と前記間隔調整部先端とで挟持し、他方の形鋼フランジの下面を前記小型ジャッキの先端で押し上げることにより、相対向する２つの形鋼フランジの目違いが修正される。 Since the invention described in Patent Document 1 has such a configuration, when correcting a misalignment, one of the opposing shaped steel flanges is sandwiched between the hook-shaped portion of the vertical fixing portion and the tip of the spacing adjusting portion. By pushing up the lower surface of the other shaped steel flange with the tip of the small jack, the misalignment between the two shaped steel flanges facing each other is corrected.

但し、特許文献１記載の発明は、概ね水平な梁フランジ等の板材継ぎ目を主たる対象としており、縦向き姿勢で板材継ぎ目を溶接する際の目違い修正については想定されておらず、その課題に対する解決手段についての記載はなく、何らの示唆もない。 However, the invention described in Patent Document 1 mainly targets plate seams such as generally horizontal beam flanges, and does not assume correction of misalignment when welding plate seams in a vertical posture. There is no description of the solution and no suggestion.

また、特許文献１記載の発明の前記小型ジャッキは、フランジ（板材）を上向きに押して、目違いを減らすように相対するフランジの位置関係を調整可能とするが、仮に、特許文献１記載の発明を縦向き姿勢の板材継ぎ目に適用した場合（例えば、ウェブを水平配置したＨ形鋼のフランジ同士の溶接継ぎ目等）は、前記小型ジャッキは板材を横向き（水平）に押すことになり、上向きに押す時のような梁の自重に相当する抵抗力がないので安定（力の釣合い）が保たれず、別途脱落防止等安定化のための措置が必要である。 Further, the small jack of the invention described in Patent Document 1 makes it possible to adjust the positional relationship between the flanges facing each other so as to reduce the misalignment by pushing the flange (plate material) upward, but the invention described in Patent Document 1 is tentatively described. When is applied to a plate material seam in a vertical orientation (for example, a welded seam between flanges of H-shaped steel in which a web is horizontally arranged), the small jack pushes the plate material sideways (horizontally) and upwards. Since there is no resistance force equivalent to the weight of the beam as when pushing it, stability (balance of force) cannot be maintained, and separate measures for stabilization such as prevention of falling off are required.

本発明は、ＣＴ形断面部材のウェブのような板材同士を、縦向き姿勢で溶接する場合に、その継ぎ目に生じる板材の目違いを簡易な手段で修正できる、板材継ぎ目の目違い修正治具を提供するものである。 INDUSTRIAL APPLICABILITY The present invention is a jig for correcting misalignment of plate material seams, which can correct misalignment of plate materials generated at the seams when welding plate materials such as webs of CT-shaped cross-sectional members in a vertical posture. Is to provide.

前記課題に対する本発明の解決手段は、以下のような構成から成る板材継ぎ目の目違い修正治具である。
１）目違い修正治具は、基板の両端付近に設けられた位置決め部と、前記位置決め部の間に設けられた加力部と、当該加力部の間に配設されるエンドタブ（以下、タブと略す。）と、そのタブを板材継ぎ目の端部小口に当接するタブ押えボルトと、から構成される。
２）前記位置決め部は、Ｊ字状凹部を形成する基部と、当該基部に固定された長ナットに内向きで螺合された１本のボルトと、から成る。
３）前記加力部は、前記板材継ぎ目を挟んで両側に位置するように設けられており、Ｕ字状凹部を形成する基部と、当該基部に固定された１対の長ナットに内向きで螺合された１対のボルトと、から成る。
４）前記タブ押えボルトは、前記基板（裏面または表面）に固定されたナットに、もしくは前記基板に切られた雌ねじに螺合され、前記基板を貫通して前記タブ押えボルトの先端が前記エンドタブに当接される。
The means for solving the above-mentioned problems of the present invention is a jig for correcting misalignment of plate material seams having the following configuration.
1) The misalignment correction jig is a positioning portion provided near both ends of the board, a force portion provided between the positioning portions, and an end tab (hereinafter referred to as an end tab) arranged between the force portions. It is abbreviated as a tab.) And a tab holding bolt that abuts the tab on the edge of the end of the plate joint.
2) The positioning portion includes a base portion forming a J-shaped recess and a single bolt screwed inward to a long nut fixed to the base portion.
3) The applying portion is provided so as to be located on both sides of the plate material seam, and faces inward to a base forming a U-shaped recess and a pair of long nuts fixed to the base. It consists of a pair of screwed bolts.
4) The tab presser bolt is screwed into a nut fixed to the substrate (back surface or front surface) or a female screw cut on the substrate, and the tip of the tab presser bolt penetrates the substrate and the tip of the tab presser bolt ends . It comes into contact with the tab.

前記タブは、セラミックス製も使用でき、板材継ぎ目の開先形状に合わせて選択すればよい。もし、既成品のタブが使用できない場合は、平板汎用タブを用いて板材継ぎ目の端部小口との隙間を確保するスペーサーを設けてもよい。また、持ち運びのための取手を、前記基板に取り付けてもよい。 The tab may be made of ceramics, and may be selected according to the groove shape of the plate material seam. If the off-the-shelf tab cannot be used, a flat plate general-purpose tab may be used to provide a spacer for securing a gap between the end edge of the plate joint and the edge. Further, a handle for carrying may be attached to the substrate.

本発明は以上のような構成であるので、縦向き姿勢で溶接しようとする板材継ぎ目を跨いで、前記基板の両端付近にある前記位置決め部のボルトで締め付けて前記板材を固定し、次に、前記板材継ぎ目を跨いで配置された前記加力部のボルトで前記板材を両側面から、目違いが修正されるまで締め付ければ、前記板材継ぎ目の目違いは容易に修正される。 Since the present invention has the above configuration, the plate material is fixed by tightening with bolts of the positioning portion near both ends of the substrate across the plate material seam to be welded in the vertical posture, and then the plate material is fixed. If the plate material is tightened from both side surfaces with bolts of the force portion arranged so as to straddle the plate material seam until the misalignment is corrected, the misalignment of the plate material seam is easily corrected.

また本発明の第２手段は、前記基板の両端部付近に設けられた前記位置決め部の一方を、前記加力部と同じように、Ｕ字状凹部を形成する基部と、当該基部に固定された１対の長ナットに内向きで螺合された１対のボルトと、を有する位置決め部に置き換えたものである。 Further, in the second means of the present invention, one of the positioning portions provided near both ends of the substrate is fixed to the base portion forming the U-shaped recess and the base portion in the same manner as the force portion. It is replaced with a positioning portion having a pair of bolts screwed inward to a pair of long nuts.

本発明の第２手段は、前記基板の両端部付近に設けられた前記位置決め部の一方が、前記加力部と同じく１対のボルトを有するので、板材継ぎ目を挟んで相対する板材の厚さが異なる場合に、両板材の板厚の差に合わせて前記ボルトの出寸法を調整することにより、目違いを修正しようとする板材の位置決めが可能となる。 In the second means of the present invention, since one of the positioning portions provided near both ends of the substrate has a pair of bolts like the applied portion, the thickness of the plate materials facing each other across the plate material seam. When the above is different, by adjusting the protruding dimension of the bolt according to the difference in the plate thickness of both plate materials, it is possible to position the plate material for which the misalignment is to be corrected.

以上の本発明では、前記板材継ぎ目の端部小口のタブは、タブ押さえボルトにより仮固定され、適度な溶着金属の溜り場が確保されるので、この部分での溶接欠陥が生じ難い。 In the above invention, the tab at the end edge of the plate material seam is temporarily fixed by the tab holding bolt to secure an appropriate pooling place for the welded metal, so that welding defects are unlikely to occur at this portion.

また、板材継ぎ目の両側で板材が両面からボルトにより挟持されるので、溶接熱による変形が拘束され、良好な仕上がり状態が得られる。特許文献１記載の発明では、相対するフランジの一方は両面から挟持されるが、他方は片面から小型ジャッキで押し付けられるだけなので、溶接熱による変形の拘束力は不十分である。 Further, since the plate material is sandwiched by bolts from both sides on both sides of the plate material seam, deformation due to welding heat is restrained, and a good finished state can be obtained. In the invention described in Patent Document 1, one of the opposing flanges is sandwiched from both sides, but the other is only pressed from one side by a small jack, so that the binding force of deformation due to welding heat is insufficient.

また、溶接完了後に本発明を取り外した後においては、従来のエレクションピース切除のような後作業を必要としない。 Further, after the present invention is removed after the welding is completed, the post-work unlike the conventional erection piece cutting is not required.

本発明は、以上のような板材継ぎ目の目違い修正治具であるので、以下のような効果がある。 Since the present invention is the jig for correcting the misalignment of the plate material seams as described above, it has the following effects.

（1）現場にて、縦向き姿勢で溶接しようとする板材継ぎ目の目違い修正が簡単、確実にできる。
（2）タブは、タブ押さえボルトにより板材継ぎ目の端部小口に仮固定され、適度な溶着金属の溜り場が確保されるので、この部分での溶接欠陥が生じ難い。
（3）厚さの異なる板材同士の溶接であっても対応可能であって、板厚が厚い場合のＫ型開先溶接にも、適当なタブを選択して使用することができるので、問題なく使用できる。
（4）板材継ぎ目の両側で板材が両面からボルトにより挟持されるので、溶接熱による変形が拘束され、良好な仕上がり状態が得られる。
（5）セラミックス製タブを用いた場合、溶接完了後に本発明を取り外し、必要に応じてグラインダーで仕上げた後は、その他の作業は不要で全て完了する。 (1) At the site, it is easy and reliable to correct the seam of the plate material to be welded in the vertical posture.
(2) The tab is temporarily fixed to the edge of the end of the plate joint by the tab holding bolt, and an appropriate pool of welded metal is secured, so welding defects are unlikely to occur in this portion.
(3) Welding of plates with different thicknesses is also possible, and K-shaped groove welding when the plate thickness is thick can also be used by selecting an appropriate tab, which is a problem. Can be used without.
(4) Since the plate material is sandwiched by bolts from both sides on both sides of the plate material seam, deformation due to welding heat is restrained and a good finished state can be obtained.
(5) When a ceramic tab is used, the present invention is removed after welding is completed, and if necessary, finished with a grinder, and then all other work is not required and all is completed.

Tighten with bolts 6 and 6. At this time, since the inner side surfaces 3b and 3b of the two bases 3a and 3a are arranged so as to be in the same plane, the reference positions of the web plates W and W having the same thickness are fixed.

この時、ウェブ板材Ｗ、Ｗの板材継ぎ目１０２では、板厚方向にずれて目違いが生じているので、加力部４、４のボルト６、６、…の出入り寸法を調整しながら、ウェブ板材Ｗ、Ｗをその両側から締め付けることによって目違いを修正する（図３（d））。 At this time, in the plate material seams 102 of the web plate materials W and W, there is a misalignment in the plate thickness direction, so that the web is adjusted while adjusting the entrance / exit dimensions of the bolts 6, 6, ... The misalignment is corrected by tightening the plate materials W and W from both sides (FIG. 3 (d)).

目違いが修正された後、基板２の裏側に固定されたナット７ａに螺合されたタブ押えボルト７を回転させてタブ５を板材継ぎ目１０２下端の端部小口に当接させる。この時、板材継ぎ目１０２の開先形状に適したタブの既製品がない場合、平板汎用タブをタブ５に用いて、板材継ぎ目１０２下端の端部小口とタブ５との隙間を確保するためにスペーサー５ａ、５ａを挟んでおく（図３（b））。 After the misalignment is corrected, the tab holding bolt 7 screwed to the nut 7a fixed to the back side of the board 2 is rotated to bring the tab 5 into contact with the end edge of the lower end of the plate material seam 102. At this time, if there is no ready-made tab for the groove shape of the plate material seam 102, a flat plate general-purpose tab is used for the tab 5 in order to secure a gap between the end edge of the lower end of the plate material seam 102 and the tab 5. Spacers 5a and 5a are sandwiched (FIG. 3 (b)).

以上のようにセットされた状態にて、トラス部材１０１のフランジおよびウェブの溶接を行うが、フランジについては、下向き姿勢で作業できる一般的なレ型開先の完全溶け込み溶接とすればよく、目違いの修正は従来方法によればよい。 Welding of the flange and web of the truss member 101 is performed in the state set as described above, but the flange may be completely penetration welded with a general re-shaped groove that can be operated in a downward posture. The difference may be corrected by the conventional method.

一方、ウェブは、ウェブ板材Ｗ、Ｗの両側からの縦向き姿勢になるが、加力部４、４のボルト６、６、…によって溶接熱による変形が拘束されるので、板材継ぎ目１０２の開先形状（レ型、Ｋ型等）を気にすることなく、溶接することが出来る。 On the other hand, the web is in a vertical posture from both sides of the web plate materials W and W, but the deformation due to welding heat is restrained by the bolts 6, 6, ... Of the force portions 4, 4 and the plate material seam 102 is opened. Welding can be done without worrying about the tip shape (re-type, K-type, etc.).

縦向き姿勢では、溶接中に溶着金属が下向きに流れるが、板材継ぎ目１０２下端の端部小口に、スペーサー５ａ、５ａによって、タブ５との間に適度な溶着金属の溜り場となる隙間が確保されるので、溶接始終端部に発生し易い溶接欠陥が生じ難くなる。 In the vertical posture, the weld metal flows downward during welding, but the spacers 5a and 5a secure a gap between the tab 5 and the weld metal at the end edge of the lower end of the plate seam 102, which serves as a suitable pool for the weld metal. Therefore, welding defects that are likely to occur at the start and end of welding are less likely to occur.

第１実施例では、トラス部材１０１のウェブ板材Ｗと節点部材１００のブラケット１００ａのウェブ板材Ｗの板厚が同じ場合であったが、例えば、ブラケット１００ａのウェブ板材Ｗの方が厚い場合に、両ウェブ板材Ｗ、Ｗの板厚芯を一致させることができない。 In the first embodiment, the thickness of the web plate W of the truss member 101 and the web plate W of the bracket 100a of the node member 100 are the same, but for example, when the web plate W of the bracket 100a is thicker. The plate thickness cores of both web plate materials W and W cannot be matched.

そこで、第２実施例は、図４に図示のように、トラス部材１０１のウェブ板材Ｗとブラケット１００ａのウェブ板材Ｗ1の板厚に差があっても柔軟に対応できるようにするため、第１実施例では２つあった位置決め部３を１つとし、もう１つを加力部４と同じ構造の位置決め部３’に置換えた場合である。 Therefore, in the second embodiment, as shown in FIG. 4, even if there is a difference in the plate thickness between the web plate material W of the truss member 101 and the web plate material W1 of the bracket 100a, the first embodiment can flexibly cope with the difference. In the embodiment, the two positioning portions 3 are replaced with one, and the other is replaced with a positioning portion 3'having the same structure as the applying portion 4.

このようにすることにより、先ずトラス部材１０１のウェブ板材Ｗは位置決め部３で押さえ、ブラケット１００ａのウェブ板材Ｗ１は、その板厚芯がトラス部材１０１のウェブ板材Ｗの板厚芯に一致するように、位置決め部３’のボルト６、６の出入り寸法を調整しながらウェブ板材Ｗ１を締め付けて固定することができる。 By doing so, first, the web plate W of the truss member 101 is pressed by the positioning portion 3, and the web plate W1 of the bracket 100a has a plate thickness core that matches the plate thickness core of the web plate W of the truss member 101. In addition, the web plate material W1 can be tightened and fixed while adjusting the entrance / exit dimensions of the bolts 6 and 6 of the positioning portion 3'.

加力部４、４による目違いの修正は、第１実施例と同様に、ウェブ板材Ｗ、Ｗ１をその両側からボルト６、６、…で締め付ければよい。 To correct the misalignment by the force portions 4 and 4, the web plate materials W and W1 may be tightened from both sides of the web plates W and W1 with bolts 6, 6, and so on, as in the first embodiment.

以上の実施例は、ＣＴ形断面部材のウェブ板を縦向き姿勢で溶接する場合で説明したが、例えば、Ｈ形断面材のウェブが水平配置されフランジが鉛直になっている場合等においても、そのフランジの継ぎ目に対して、前記同様に本発明の使用が可能であることは言うまでもない。 The above embodiment has been described in the case where the web plate of the CT-shaped cross-section member is welded in a vertical posture. However, for example, even when the web of the H-shaped cross-section member is horizontally arranged and the flange is vertical. It goes without saying that the present invention can be used for the seam of the flange in the same manner as described above.

以上のように、本発明に係る板材継ぎ目の目違い修正治具は、縦向き姿勢での溶接において、板材継ぎ目の目違いを容易に修正でき、かつ、溶接熱による変形を拘束できる。 As described above, the jig for correcting the seam of the plate material according to the present invention can easily correct the seam of the plate material in the welding in the vertical orientation and can restrain the deformation due to the welding heat.

また、厚さの異なる板材同士の溶接であっても対応可能であり、板厚が厚い場合のＫ型開先溶接にも問題なく使用できる。 Further, it is possible to weld plates having different thicknesses to each other, and it can be used without any problem in K-shaped groove welding when the plate thickness is thick.

例えば、建設現場において鉄骨部材の鉛直板材同士の継ぎ目を溶接する場合、工場での溶接のように、部材の向きを下向き姿勢に変えることが容易にできないので、縦向き姿勢で行わざるを得ないが、本発明は、板材継ぎ目の目違い修正が容易であって、かつ板材継ぎ目の端部小口のタブも同時に仮固定できるので、溶接継ぎ目の性能確保と現場の作業効率向上に大いに貢献する。 For example, when welding the seams between vertical plate members of steel frame members at a construction site, it is not easy to change the direction of the members to the downward position as in the case of welding at a factory, so it is necessary to perform it in a vertical position. However, the present invention greatly contributes to ensuring the performance of the welded seam and improving the work efficiency at the site because it is easy to correct the misalignment of the plate material seam and the tab at the end edge of the plate material seam can be temporarily fixed at the same time.
