Description
本発明は、溶接方法に関する。 The present invention relates to a welding method.
建設現場において、鉄筋や鉄骨等の接合にアーク溶接が採用されている。アーク溶接では、例えば、溶接対象である鉄筋や鉄骨等の母材に、アースケーブルが接続されたアース部材が取り付けられ、また、溶接棒側に電圧供給ケーブルが接続された状態で、母材と溶接棒との間に溶接電流（大電流）を流してアークを発生させることにより、母材の溶接部と溶接棒とを溶融して溶接が行われる（例えば、特許文献１参照）。 At construction sites, arc welding is used for joining reinforcing bars and steel frames. In arc welding, for example, a base member such as a reinforcing bar or steel frame to be welded is attached with a ground member connected to a ground cable, and a voltage supply cable is connected to the welding rod side. By causing a welding current (large current) to flow between the welding rod and generating an arc, the welded portion of the base metal and the welding rod are melted to perform welding (see, for example, Patent Document 1).
上記のアーク溶接等のように電気エネルギーを用いて行う電気溶接では、火花の発生は避けられない。特に、母材の表面は、凹凸形状であったり、埃や錆、塗装片等の異物が付着していたりする場合が多いため、母材とアース部材との接触が悪く、火花が発生し易い。この溶接時に発生する火花が周囲に飛散すると、作業者の火傷や作業現場の火災に繋がり危険である。 In electric welding performed using electric energy such as the arc welding described above, the occurrence of sparks is inevitable. In particular, since the surface of the base material is often uneven, or foreign matter such as dust, rust, or paint pieces adheres to it, the contact between the base material and the ground member is poor and sparks are likely to occur. . If sparks generated at the time of welding are scattered to the surroundings, it is dangerous because it may lead to burns of the worker and a fire at the work site.
本発明は、このような事情に鑑みてなされたものであり、溶接時に発生する火花の飛散を抑制することを目的とする。 This invention is made | formed in view of such a situation, and it aims at suppressing the scattering of the spark which generate | occur | produces at the time of welding.

このような溶接方法によれば、カバーの開口部の周縁と溶接対象部材との間から、溶接時に発生する火花が飛散してしまうことを抑制できる。
In order to achieve this object, the welding method of the present invention causes the welding target member to adsorb the portion of the magnet exposed from the opening of the cover among the ground members in which the magnet connected to the ground cable is covered with the cover. The welding is performed by grounding the member to be welded and providing a fire-resistant putty that seals between the periphery of the opening of the cover and the member to be welded. Is the method.
According to such a welding method, it is possible to suppress sparks generated during welding from being scattered between the periphery of the opening of the cover and the member to be welded.

このような溶接方法によれば、アースケーブル又は接続部材を通したカバーの孔から、溶接時に発生する火花が飛散してしまうことを抑制できる。
In this welding method, the cover is provided with a hole through which the connection member between the ground cable or the ground cable and the magnet is passed, and the hole of the cover through which the ground cable or the connection member is passed is formed. The welding method is characterized in that electric welding is performed in a state in which a sealed refractory putty is provided.
According to such a welding method, it is possible to suppress sparks generated during welding from being scattered from the hole of the cover through which the ground cable or the connection member is passed.

このような溶接方法によれば、溶接時に発生する火花が耐火性シート内に閉じ込められるため、火花の飛散を抑制することができる。
In this welding method, electrical welding is performed in a state where the ground member is covered with a refractory sheet.
According to such a welding method, since sparks generated during welding are confined in the fireproof sheet, it is possible to suppress scattering of the sparks.
本発明によれば、溶接時に発生する火花の飛散を抑制することができる。 ADVANTAGE OF THE INVENTION According to this invention, the scattering of the spark which generate | occur | produces at the time of welding can be suppressed.
以下、本発明の一実施形態を、図面を参照しながら説明する。図１Ａは、被覆材２１で覆われた建築部材２０にピン部材２２を溶接する溶接方法を示す図であり、図１Ｂは、比較例におけるアース部材３０の取り付け方法を示す図である。図２は、アース部材３０が有するカバー３２の下部の周囲に耐火性パテ３６を設けた状態を示す図である。図３は、アース部材３０が有するカバー３２の孔３２２を耐火性パテ３７で塞いだ状態を示す図である。図４は、アース部材３０を耐火性シート３８で覆った状態を示す図である。例えば、建物における鉄筋や鉄骨、空調ダクト等の建築部材２０の表面を、耐火断熱材や保温材、防音材等の被覆材２１で覆うことがある。本実施形態では、建築部材２０を覆う被覆材２１にピン部材２２の脚部を差し込み、溶接装置１によりピン部材２２と建築部材２０とを溶接することにより、建築部材２０に対して被覆材２１を固定する実施形態を例に挙げる。なお、ピン部材２２は、導電性の材料から構成され、例えば、円盤状の頭部に取り付けられた脚部の先端がやり状に尖鋭されたもの等が挙げられる。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1A is a diagram illustrating a welding method for welding the pin member 22 to the building member 20 covered with the covering material 21, and FIG. 1B is a diagram illustrating a method for attaching the ground member 30 in the comparative example. FIG. 2 is a view showing a state in which a fireproof putty 36 is provided around the lower portion of the cover 32 of the ground member 30. FIG. 3 is a view showing a state where the hole 322 of the cover 32 included in the ground member 30 is closed with a fire-resistant putty 37. FIG. 4 is a view showing a state in which the ground member 30 is covered with the fireproof sheet 38. For example, the surface of a building member 20 such as a reinforcing bar, steel frame, or air conditioning duct in a building may be covered with a covering material 21 such as a fireproof heat insulating material, a heat insulating material, or a soundproof material. In the present embodiment, the leg portion of the pin member 22 is inserted into the covering material 21 that covers the building member 20, and the pin member 22 and the building member 20 are welded by the welding device 1, thereby covering the building member 20 with the covering material 21. An embodiment in which is fixed is taken as an example. Note that the pin member 22 is made of a conductive material, and examples thereof include a member in which the tip of a leg attached to a disk-shaped head is sharply sharpened.
また、本実施形態では、溶接装置１をコンデンサ放電式の溶接装置とし、溶接装置１は、スタッドガン１０と、電源装置２と、アースケーブル３と、電圧供給ケーブル４と、アース部材３０と、を有する。アースケーブル３の一端はアース部材３０に接続され、他端は電源装置２におけるアースに繋がる端子に接続される。電圧供給ケーブル４の一端はスタッドガン１０に接続され、他端は電源装置２における電圧供給回路（コンデンサ）に繋がる端子に接続される。 Moreover, in this embodiment, the welding apparatus 1 is a capacitor discharge type welding apparatus, and the welding apparatus 1 includes a stud gun 10, a power supply device 2, a ground cable 3, a voltage supply cable 4, a ground member 30, Have One end of the ground cable 3 is connected to the ground member 30, and the other end is connected to a terminal connected to the ground in the power supply device 2. One end of the voltage supply cable 4 is connected to the stud gun 10, and the other end is connected to a terminal connected to a voltage supply circuit (capacitor) in the power supply device 2.
スタッドガン１０は、ガン形状の本体部１１と、ピン部材２２を保持するプラグ１２と、本体部１１内から突出した端部がプラグ１２に接続される保持ロッド１３と、を有する。保持ロッド１３は、軸方向に往復移動可能であり、本体部１１内にて不図示のコイルばねに挿通されており、保持ロッド１３が軸方向の後側（本体部１１側）に移動すると、コイルばねにより軸方向の前側（建築部材２０側）に向かう付勢力が保持ロッド１３に掛かる。よって、プラグ１２に保持されたピン部材２２を建築部材２０に圧接することができる。また、プラグ１２は円柱状の永久磁石であり、プラグ１２にピン部材２２の頭部が着脱自在に吸着される。保持ロッド１３は導電性の材料から構成され、電源装置２から電圧供給ケーブル４によりスタッドガン１０の本体部１１内に供給された溶接電流（大電流）が、保持ロッド１３及びプラグ１２を介して、ピン部材２２に供給される。 The stud gun 10 includes a gun-shaped main body 11, a plug 12 that holds the pin member 22, and a holding rod 13 whose end protruding from the main body 11 is connected to the plug 12. The holding rod 13 can reciprocate in the axial direction, is inserted through a coil spring (not shown) in the main body 11, and when the holding rod 13 moves to the rear side in the axial direction (the main body 11 side), The urging force toward the front side in the axial direction (the building member 20 side) is applied to the holding rod 13 by the coil spring. Therefore, the pin member 22 held by the plug 12 can be pressed against the building member 20. The plug 12 is a cylindrical permanent magnet, and the head of the pin member 22 is detachably attached to the plug 12. The holding rod 13 is made of a conductive material, and the welding current (large current) supplied from the power supply device 2 into the main body 11 of the stud gun 10 by the voltage supply cable 4 passes through the holding rod 13 and the plug 12. , Supplied to the pin member 22.
アース部材３０は、建築部材２０からアースをとるためのものであり、磁石３１（永久磁石）と、磁石３１を覆う金属性のカバー３２と、磁石３１の上面から上方に突出した導電性の突出部材３３と、突出部材３３の上面から上方に向かって立設するスタッドボルト３４と、スタッドボルト３４に螺合するナット３５と、を有する。ここでは、磁石３１を円柱形状とし、カバー３２を有底円筒形状とし、カバー３２の開口部３２１から磁石３１の底面３１ａが露出している。また、カバー３２の天井部（上部）には、突出部材３３を通す孔３２２が設けられている。なお、カバー３２は、金属製のものに限らず、難燃性又は不燃性の部材で構成されたものであればよい。 The ground member 30 is for grounding the building member 20, and includes a magnet 31 (permanent magnet), a metallic cover 32 that covers the magnet 31, and a conductive protrusion that protrudes upward from the upper surface of the magnet 31. A member 33, a stud bolt 34 erected upward from the upper surface of the protruding member 33, and a nut 35 screwed into the stud bolt 34 are included. Here, the magnet 31 has a columnar shape, the cover 32 has a bottomed cylindrical shape, and the bottom surface 31 a of the magnet 31 is exposed from the opening 321 of the cover 32. In addition, a hole 322 through which the protruding member 33 is passed is provided in the ceiling portion (upper part) of the cover 32. Note that the cover 32 is not limited to a metal one, but may be any cover made of a flame-retardant or non-flammable member.
比較例におけるアース部材３０の取り付け方法では、図１Ｂに示すように、まず、カバー３２の開口部３２１から露出している磁石３１の底面３１ａを、建築部材２０の両側面２０ａ，２０ｂのうちの一方側の面（ここでは上面２０ａ）に吸着させる。そして、突出部材３３から立設するスタッドボルト３４に、アースケーブル３の端子３ａの孔を通し、ナット３５を締結する。そうすると、アースケーブル３の端子３ａが突出部材３３に接触した状態で固定され、建築部材２０とアースケーブル３は、磁石３１及び突出部材３３を介して電気的に接続される。このように、磁石３１を用いたアース部材３０は、例えばクリップ形状のアース部材では挟持できない部位にも、取り付けることができる。 In the attachment method of the ground member 30 in the comparative example, as shown in FIG. 1B, first, the bottom surface 31 a of the magnet 31 exposed from the opening 321 of the cover 32 is made of the both side surfaces 20 a and 20 b of the building member 20. It is adsorbed on one surface (here, the upper surface 20a). Then, a hole of the terminal 3 a of the ground cable 3 is passed through a stud bolt 34 erected from the protruding member 33, and a nut 35 is fastened. Then, the terminal 3 a of the earth cable 3 is fixed in a state where it contacts the protruding member 33, and the building member 20 and the earth cable 3 are electrically connected via the magnet 31 and the protruding member 33. Thus, the ground member 30 using the magnet 31 can be attached to a portion that cannot be clamped by, for example, a clip-shaped ground member.
建築部材２０にアース部材３０を取り付けた後は、スタッドガン１０のプラグ１２にピン部材２２を装着し、コイルばねの付勢力によりピン部材２２の先端を建築部材２０に圧接した状態で、スタッドガン１０のスイッチをオンする。そうすると、電源装置２からの溶接電流がピン部材２２の先端と建築部材２０との間に流れてアークが発生し、ピン部材２２と建築部材２０との接触箇所が溶融し、ピン部材２２が建築部材２０に対して立設した状態で溶接される。よって、ピン部材２２により被覆材２１が建築部材２０に固定される。 After the ground member 30 is attached to the building member 20, the pin member 22 is mounted on the plug 12 of the stud gun 10, and the stud gun 22 is pressed against the building member 20 by the biasing force of the coil spring. Turn on the 10 switch. If it does so, the welding current from the power supply device 2 will flow between the front-end | tip of the pin member 22, and the building member 20, an arc will generate | occur | produce, the contact location of the pin member 22 and the building member 20 will fuse | melt, and the pin member 22 will be built. It welds in the state standing with respect to the member 20. FIG. Therefore, the covering material 21 is fixed to the building member 20 by the pin member 22.
このように、電気エネルギーを用いて溶接を行う場合、火花の発生は避けられない。特に、建築部材２０の表面は、凹凸形状であったり、埃や錆、塗装片等の異物が付着していたりする場合が多いため、建築部材２０とアース部材３０（磁石３１）との接触が悪くなり易く、アース部材３０の取り付け箇所にて激しく火花が発生してしまう。その火花が飛散すると、作業者の火傷や作業現場の火災に繋がり危険である。本実施形態のアース部材３０は、金属性のカバー３２で磁石３１が覆われているため、溶接時に発生する火花の飛散をある程度は抑制することができる。しかし、図１Ｂに示すように、カバー３２の底面３２ａ（開口部３２１の周縁３２ａ）を建築部材２０の上面２０ａに密着させることは難しく、その隙間から火花が飛散してしまう。また、突出部材３３を通すためにカバー３２に設けられた孔３２２の隙間からも火花が飛散してしまう。 Thus, when welding is performed using electric energy, the occurrence of sparks is inevitable. In particular, since the surface of the building member 20 is often uneven or has foreign matter such as dust, rust, or paint pieces attached thereto, contact between the building member 20 and the earth member 30 (magnet 31) is likely to occur. It is easy to get worse, and sparks are violently generated at the place where the ground member 30 is attached. If the sparks are scattered, it can lead to burns of workers and fires at the work site, which is dangerous. Since the magnet 31 is covered with the metallic cover 32, the ground member 30 of this embodiment can suppress the scattering of sparks generated during welding to some extent. However, as shown in FIG. 1B, it is difficult to bring the bottom surface 32a of the cover 32 (the peripheral edge 32a of the opening 321) into close contact with the upper surface 20a of the building member 20, and sparks will scatter from the gap. In addition, sparks are scattered from the gap between the holes 322 provided in the cover 32 so as to allow the protruding member 33 to pass therethrough.
そこで、本実施形態では、図２に示すように、突出部材３３を介してアースケーブル３に接続された磁石３１をカバー３２で覆ったアース部材３０のうちカバー３２の開口部３２１から露出した磁石３１の底面３１ａを建築部材２０（溶接対象部材）に吸着させることによって、建築部材２０をアースし、且つ、カバー３２の開口部３２１の周縁（底面３２ａ）と建築部材２０との間を密閉する耐火性パテ３６（難燃性又は不燃性のパテ）を設けた状態で、溶接を行う。具体的には、カバー３２の下方側端部の側面の全周に亘って耐火性パテ３６が密着するように、建築部材２０の上面２０ａ上に耐火性パテ３６を盛る。そうすることで、耐火性パテ３６によりカバー３２の内部と外部との連通が遮断され、建築部材２０と磁石３１との当接部位にて発生する火花が、建築部材２０の上面２０ａとカバー３２の周縁３２ａとの間から飛散してしまうことを抑制できる。 Therefore, in the present embodiment, as shown in FIG. 2, the magnet exposed from the opening 321 of the cover 32 of the ground member 30 in which the magnet 31 connected to the ground cable 3 via the protruding member 33 is covered with the cover 32. By adsorbing the bottom surface 31a of 31 to the building member 20 (member to be welded), the building member 20 is grounded, and the periphery of the opening 321 (the bottom surface 32a) of the cover 32 and the building member 20 are sealed. Welding is performed with the fire-resistant putty 36 (flame retardant or non-flammable putty) provided. Specifically, the fire-resistant putty 36 is placed on the upper surface 20 a of the building member 20 so that the fire-resistant putty 36 is in close contact with the entire circumference of the side surface of the lower end portion of the cover 32. By doing so, the communication between the inside and the outside of the cover 32 is blocked by the fire-resistant putty 36, and a spark generated at the contact portion between the building member 20 and the magnet 31 causes the upper surface 20 a of the building member 20 and the cover 32 to be sparked. It is possible to suppress scattering from between the peripheral edge 32a.
また、本実施形態では、図３に示すように、突出部材３３（アースケーブル３と磁石３１との接続部材）が通されたカバー３２の孔３２２を密閉する耐火性パテ３７を設けた状態で、溶接を行う。具体的には、突出部材３３の側面の全周に亘って耐火性パテ３６が密着するようにカバー３２の上面上に耐火性パテ３７を盛り、孔３２２を塞ぐ。そうすることで、耐火性パテ３７によりカバー３２の内部と外部との連通が遮断され、建築部材２０と磁石３１との当接部位にて発生する火花が、カバー３２の孔３２２から飛散してしまうことを抑制できる。なお、本実施形態では、突出部材３３がカバー３２の孔３２２を通るが、これに限らず、磁石３１に接続されたアースケーブル３がカバー３２の孔３２２を通る場合もある。 Moreover, in this embodiment, as shown in FIG. 3, in the state which provided the fireproof putty 37 which seals the hole 322 of the cover 32 where the protrusion member 33 (connection member of the earth cable 3 and the magnet 31) was passed. , Do the welding. Specifically, the refractory putty 37 is placed on the upper surface of the cover 32 so that the refractory putty 36 is in close contact with the entire circumference of the side surface of the protruding member 33, and the hole 322 is closed. By doing so, the communication between the inside and the outside of the cover 32 is blocked by the fire-resistant putty 37, and a spark generated at the contact portion between the building member 20 and the magnet 31 is scattered from the hole 322 of the cover 32. Can be suppressed. In the present embodiment, the protruding member 33 passes through the hole 322 of the cover 32, but the present invention is not limited to this, and the ground cable 3 connected to the magnet 31 may pass through the hole 322 of the cover 32.
更に、本実施形態では、図４に示すように、アース部材３０を耐火性シート３８（難燃性又は不燃性のシート）で覆った状態で、溶接を行う。特に、耐火性パテ３６，３７でカバー３２の隙間を塞いだ部位が露出しないように、アース部材３０の上から耐火性シート３８を被せる。そうすることで、耐火性パテ３６，３７では抑えきれなかった火花が耐火性シート３８内に閉じ込められるため、火花の飛散を一層抑制することができる。なお、耐火性シート３８としては、例えば、スター電器製造株式会社のスパシャッタ（スパッタシート）等を挙げることができる。 Furthermore, in this embodiment, as shown in FIG. 4, welding is performed in a state where the ground member 30 is covered with a fireproof sheet 38 (a flame retardant or nonflammable sheet). In particular, the refractory sheet 38 is placed over the ground member 30 so that the portion of the cover 32 covered with the refractory putty 36, 37 is not exposed. By doing so, since the spark that could not be suppressed by the fire-resistant putty 36, 37 is confined in the fire-resistant sheet 38, it is possible to further suppress the scattering of the spark. Examples of the fireproof sheet 38 include a spa shutter (sputter sheet) manufactured by Star Electric Manufacturing Co., Ltd.
このように、本実施形態の溶接方法では、アース部材３０に耐火性パテ３６，３７や耐火性シート３８を設けた状態で溶接を行う。そのため、火花の飛散を抑制することができ、作業者の火傷や作業現場の火災を防止でき、安全に溶接を行うことができる。また、周囲の養生も簡略化できる。また、既存のアース部材３０に対しても、耐火性パテ３６，３７や耐火性シート３８を設けるだけで火花の飛散を容易に抑制することができる。なお、耐火性パテ３６，３７や耐火性シート３８に火花が付着しても燃焼の虞がなく安全である。また、建築部材２０の上面２０ａや磁石３１の底面３１ａから異物を除去した後に、アース部材３０を取り付けることが好ましく、そうすることで、溶接時の火花の発生量を低減でき、火花の飛散を一層抑制することができる。 As described above, in the welding method of the present embodiment, welding is performed in a state in which the fireproof putty 36, 37 and the fireproof sheet 38 are provided on the ground member 30. Therefore, the scattering of sparks can be suppressed, burns of workers and fires at the work site can be prevented, and welding can be performed safely. In addition, surrounding curing can be simplified. In addition, the sparking of the existing ground member 30 can be easily suppressed by simply providing the fire-resistant putty 36, 37 and the fire-resistant sheet 38. In addition, even if a spark adheres to the refractory putty 36, 37 or the refractory sheet 38, there is no risk of combustion and it is safe. In addition, it is preferable to attach the ground member 30 after removing foreign matter from the upper surface 20a of the building member 20 or the bottom surface 31a of the magnet 31, so that the amount of sparks generated during welding can be reduced, and sparks can be scattered. Further suppression can be achieved.
以上、上記実施形態は、本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。本発明は、その趣旨を逸脱することなく、変更、改良され得ると共に、本発明にはその等価物が含まれることはいうまでもない。 As mentioned above, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
上記実施形態では、図４に示すように、カバー３２の開口部３２１の周縁３２ａや孔３２２の隙間を塞ぐ耐火性パテ３６，３７と耐火性シート３８を設けた状態で、溶接を行うとしているが、これに限らない。例えば、図２に示すように、カバー３２の開口部３２１の周縁３２ａと建築部材２０との間を密閉する耐火性パテ３６を設けただけの状態で溶接を行ってもよいし、図３に示すように、カバー３２の開口部３２１の周縁３２ａと建築部材２０との間とカバー３２の孔３２２とを密閉する耐火性パテ３６，３７を設けただけの状態で溶接を行ってもよいし、図示しないが、カバー３２の開口部３２１の周縁３２ａと建築部材２０との間を密閉する耐火性パテ３６と耐火性シート３８を設けただけの状態で溶接を行ってもよい。これらの場合にも、比較例（図１Ｂ）に比べて、溶接時の火花の発生量を低減でき、火花の飛散を抑制することができる。 In the above embodiment, as shown in FIG. 4, welding is performed in a state in which the refractory putty 36 and 37 and the refractory sheet 38 that close the gap between the peripheral edge 32 a of the opening 321 of the cover 32 and the hole 322 are provided. However, it is not limited to this. For example, as shown in FIG. 2, welding may be performed in a state in which a fire-resistant putty 36 that seals between the peripheral edge 32 a of the opening 321 of the cover 32 and the building member 20 is provided. As shown, welding may be performed in a state where fire-resistant putty 36, 37 that seals between the peripheral edge 32a of the opening 321 of the cover 32 and the building member 20 and the hole 322 of the cover 32 is provided. Although not shown, welding may be performed in a state where only the fire-resistant putty 36 and the fire-resistant sheet 38 that seal between the peripheral edge 32a of the opening 321 of the cover 32 and the building member 20 are provided. Also in these cases, compared to the comparative example (FIG. 1B), the amount of sparks generated during welding can be reduced, and the scattering of sparks can be suppressed.
また、上記実施形態では、被覆材２１で覆われた建築部材２０にピン部材２２を溶接する溶接方法を例に挙げているが、これに限らず、例えば、被覆材２１で覆われていない建築部材２０にボルト等を立設する溶接方法でもよいし、２枚の金属板を接合する溶接方法でもよい。また、アーク溶接に限らず、例えば、抵抗溶接でもよく、溶接対象部材をアースし、電気エネルギーを用いて行う電気溶接であれば、本発明が有効となる。 Moreover, in the said embodiment, although the welding method which welds the pin member 22 to the building member 20 covered with the coating | covering material 21 is mentioned as an example, it is not restricted to this, For example, the architecture which is not covered with the coating | covering material 21 A welding method in which a bolt or the like is erected on the member 20 may be used, or a welding method in which two metal plates are joined.
