Description
【０００１】[0001]
この考案は、溶接継手に係わり、更に詳しくは拘束治具を用いることなく継手 部材の凹凸嵌合部の外周面を精度良く溶接することが出来る溶接治具に関するも のである。 The present invention relates to a welded joint, and more particularly to a welding jig capable of accurately welding the outer peripheral surface of the concave-convex fitting portion of the joint member without using a restraining jig.
【０００２】[0002]
従来、流体を流通させる配管の継手部は、水密性及び気密性を保つために配管 の端末部に設けた継手部材の凹凸嵌合部を嵌合させた後、その嵌合部の継目の外 周面を溶接により一体的に接続させていた。 Conventionally, the fitting part of a pipe that allows fluid to flow is fitted with the uneven fitting part of the fitting member provided at the end of the pipe in order to maintain watertightness and airtightness, and then outside the seam of the fitting part. The peripheral surfaces were integrally connected by welding.
【０００３】[0003]
然しながら、嵌合部の継目を溶接する場合、図４及び図５に示すように継手部 材１ａ，１ｂの嵌合部２ａ，２ｂの継目同志を拘束させておくために、拘束治具 ３ａ，３ｂにより保持させておく必要があった。 このため、溶接部の一部が治具３ａ，３ｂで隠れてしまい、その結果、嵌合部 ２ａ，２ｂの継目外周を一度の操作で完全に溶接することが出来ないと言う問題 があった。 However, when welding the joints of the fitting portions, as shown in FIGS. 4 and 5, in order to restrain the joints of the fitting portions 2a, 2b of the joint members 1a, 1b, the restraining jig 3a, It was necessary to hold it by 3b. Therefore, a part of the welded part is hidden by the jigs 3a and 3b, and as a result, there is a problem that the outer circumference of the joint of the fitting parts 2a and 2b cannot be completely welded by one operation. .
【０００４】 この考案は、かかる従来の課題に着目して案出されたもので、拘束治具を特に 使用することなく継手部材の嵌合部を拘束させた状態で溶接することが出来る溶 接継手を提供することを目的とするものである。The present invention has been made in view of such conventional problems, and a welding method capable of performing welding in a state in which a fitting portion of a joint member is restrained without using a restraint jig. It is intended to provide a joint.

以下、添付図面に基づき、この発明の実施例を説明する。 なお、従来例と同一構成要素は、同一符号を付して説明は省略する。 図１は、この考案を実施した溶接継手の一部断面斜視図、図２は継手部材の結 合した状態の断面図を示し、１ａ，１ｂは配管Ｘ，Ｙの端末部を接続する継手部 材、２ａ，２ｂは継手部材１ａ，１ｂの嵌合部を示し、一方の継手部材１ａの嵌 合部２ａは、凸状に形成され、また他方の継手部材１ｂの嵌合部２ｂは、前記凸 状の嵌合部２ａが嵌合する凹状に形成されている。 Embodiments of the present invention will be described below with reference to the accompanying drawings. The same components as those in the conventional example are designated by the same reference numerals and the description thereof will be omitted. FIG. 1 is a partial cross-sectional perspective view of a welded joint embodying the present invention, and FIG. 2 is a sectional view of a joint member in a joined state. 1a and 1b are joint portions for connecting end portions of pipes X and Y. Materials 2a and 2b indicate fitting portions of the joint members 1a and 1b, the fitting portion 2a of one joint member 1a is formed in a convex shape, and the fitting portion 2b of the other joint member 1b is It is formed in a concave shape into which the convex fitting portion 2a is fitted.
【０００８】 前記嵌合部２ａ，２ｂの嵌合面には、ねじ部４ａ，４ｂが形成してあり、継手 部材１ａ，１ｂを接続する場合には、嵌合部２ａ，２ｂのねじ部４ａ，４ｂを螺 嵌させて結合するものである。 図３は、嵌合部２ａ，２ｂの間に他の異種部材６を介在させて継手部材１ａ， １ｂを接続した他の実施例を示してる。Threaded portions 4a and 4b are formed on the fitting surfaces of the fitting portions 2a and 2b. When connecting the joint members 1a and 1b, the threaded portions 4a of the fitting portions 2a and 2b are connected. , 4b are screwed together and connected. FIG. 3 shows another embodiment in which the joint members 1a and 1b are connected by interposing another different member 6 between the fitting portions 2a and 2b.
【０００９】 この考案の実施例では、継手部材１ａ，１ｂの中空部７内を流体を流通させる ために、嵌合部２ａ，２ｂを嵌合接続させた後、その外周面を溶接Ｚして施工す る。 従って、継手部材１ａ，１ｂの嵌合部２ａ，２ｂを嵌合接続させた状態で、継 目同志を拘束させておく必要があるが、この実施例では、拘束手段として、従来 のような拘束治具３ａ，３ｂを使用することなく、ねじ部４ａ，４ｂの螺嵌結合 によって継手部材１ａ，１ｂの嵌合部２ａ，２ｂを拘束出来るので、嵌合部２ａ ，２ｂの外周面を溶接する場合にも、何ら支障はなく、確実に継手部材１ａ，１ ｂの溶接を行うことが出来るものである。In the embodiment of the present invention, the fitting portions 2a and 2b are fitted and connected to each other in order to allow the fluid to flow through the hollow portions 7 of the joint members 1a and 1b, and then the outer peripheral surfaces thereof are welded Z. Construct. Therefore, it is necessary to restrain the joints while the fitting portions 2a and 2b of the joint members 1a and 1b are fitted and connected. In this embodiment, the restraint means is a restraint of the conventional type. Since the fitting portions 2a, 2b of the joint members 1a, 1b can be restrained by the screw fitting connection of the screw portions 4a, 4b without using the jigs 3a, 3b, the outer peripheral surfaces of the fitting portions 2a, 2b are welded. In this case, the joint members 1a and 1b can be reliably welded without any trouble.
【００１０】 また、図３に示すように嵌合部２ａ，２ｂの間に他の異種部材６を介在させて 継手部材１ａ，１ｂを接続させる場合にも、上記第１実施例と同様に、溶接作業 に何ら支障はなく、確実に溶接作業を行うことが出来るものである。Further, as shown in FIG. 3, also when the joint members 1a and 1b are connected by interposing another dissimilar member 6 between the fitting portions 2a and 2b, as in the first embodiment, There is no obstacle to the welding work, and the welding work can be performed reliably.
