この発明は、鉄骨構造物等に用いられるかと継手溶接構
造に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a dovetail welded joint structure used in steel structures and the like.
従来、かど継手の溶接は、第１１図のように、裏あて金
２１を用いていた。のど厚は、突き合わす側のプレート
２２の板厚と同じである。裏あて金２１の一部も溶は込
ませている。Conventionally, corner joints have been welded using a backing metal 21, as shown in FIG. The throat thickness is the same as the plate thickness of the plate 22 on the abutting side. A part of the backing metal 21 is also melted in.
しかし、これでは、裏あて金２１という別部材が辛要で
あるため、コストが高（なり、また裏あて金２１の収ま
りが悪いという問題点があった。However, this requires a separate member called the backing metal 21, which results in high costs, and there are also problems in that the backing metal 21 does not fit well.
そこで、裏あて金を用いず、表側から溶接し、裏はつり
をした後に裏側から溶接する方法もある。Therefore, there is a method of welding from the front side without using a backing metal, and then welding from the back side after hanging the back side.
しかし、これでは、作業性が悪い。そこで、裏はつりの
作業をなくすと、今度は、裏側部分の溶は込みが十分で
な（、溶接強度がでない。However, this method has poor workability. Therefore, if we eliminate the back chisel work, the weld penetration on the back side will not be sufficient (and the weld strength will be insufficient).
この発明の目的は、裏あて金なしで十分な溶接強度が得
られコストが安（て収まりが良くかつ裏はつりが不要で
作業性の良いかと継手溶接構造を提供することである。It is an object of the present invention to provide a welded joint structure that provides sufficient welding strength without a backing metal, is inexpensive, and has good workability without the need for backing.
この発明のかと継手溶接構造は、一端の角部を除去して
斜面部を形成した第１の部材と、この第１の部材の一端

先部を形成した第２の部材と、前記開先部に盛られた第
１ビード部と、この第１ビード部の前記接触部を隔てた
反対側に盛られた第２ビード部とを備えたものである。In the heel joint welding structure of the present invention, there is provided a first member in which a corner portion of one end is removed to form a sloped portion, and the first member contacts the one end of the first member in a perpendicular state to form a gap between the sloped portion and the first member. A second member having a groove formed therein, a first bead portion formed in the groove, and a second bead portion formed on the opposite side of the first bead portion across the contact portion. It is prepared.

することにより前記斜面部との間に開先部を形成した第
２の部材を設け、前記開先部に盛られた第１ビード部を

により、前記接触部の近傍において第１ビード部の溶接
時の溶は込み範囲と第２ビード部の溶接時の溶は込み範
囲とを重複させることができる。そのため、溶接欠陥が
生じにくく、裏あて金なしで十分な溶接強度が得られ、
コストが安くて収まりが良い。According to this invention, a second member is provided which forms a groove portion between the slope portion by contacting the first member that forms a slope portion, and a first member that is built up in the groove portion is provided. Since a bead portion is provided and a second bead portion raised on the opposite side of the first bead portion is provided, by appropriately setting the width of the contact portion, the width of the first bead portion can be increased in the vicinity of the contact portion. The penetration range during welding and the penetration range during welding of the second bead portion can overlap. Therefore, welding defects are less likely to occur, and sufficient welding strength can be obtained without a backing metal.
It's cheap and fits well.
また、裏はつりが不要なので、作業性が良い。Also, since there is no need to hang the back side, it is easy to work with.

部６を設けたものである。One embodiment of the present invention will be described with reference to FIGS. 1 to 7. This dovetail joint welding structure is provided with a first member 1 in which a corner portion of one end is removed to form a sloped portion 3, and by contacting one end of the first member l in a perpendicular state, the sloped portion 3 is formed.
A second member having a groove portion 4 formed therebetween is provided, a first bead portion 5 is provided on the groove portion 4, and the contact portion 7 of the first bead portion 5 is separated from the first bead portion 5. A second bead portion 6 is provided on the opposite side.

の端面との間にＶ形の開先部４を形成している。接触部
７は２■程度以下の幅が確保されている（第３図）。In FIG. 1, the first member 1 and the second member 2 are iron plates, and the first member 1 is arranged vertically and the second member 2 is arranged horizontally. The end surface of the second member 2 is abutted against the upper end side surface of the first member 1 . The slope part 3 is the first
It is provided facing upward at the upper end of the member 1, and forms a V-shaped groove portion 4 between it and the end surface of the second member. The contact portion 7 has a width of approximately 2 mm or less (Fig. 3).
第２図において、Ａは第１ビード部５の溶接時の溶は込
み範囲を示し、Ｂは第２ビード部６の溶接時の溶は込み
範囲を示している。In FIG. 2, A indicates the penetration range during welding of the first bead portion 5, and B indicates the penetration range during welding of the second bead portion 6.
接触部７の幅を２ｍ程度以下としたのは、溶接時の寸法
精度を確保するためには前記幅は広い方が良いが、前記
溶は込み範囲を重複させるためには前記幅は狭い方が良
く、両者が満足される幅を選択した結果である。The reason why the width of the contact portion 7 is set to be approximately 2 m or less is that in order to ensure dimensional accuracy during welding, it is better to have a wider width, but in order to overlap the welding range, it is better to have a narrower width. This is the result of selecting a width that satisfies both conditions.
なお、接触部７０幅を太き（取り過ぎると、第３図のよ
うに、第１ビード部５と第２ビード部６の溶接時の溶は
込み範囲が重ならず、十分な溶接強度が得られない。If the width of the contact part 70 is made too wide (as shown in Fig. 3), the welding penetration range during welding of the first bead part 5 and the second bead part 6 will not overlap, resulting in insufficient welding strength. I can't get it.

FIG. 5 shows a case where an end plate 9 is welded to the end face of a beam 8 made of an H-shaped cross section, and FIG. 6 shows a case where a column base plate 11 is welded to the bottom face of a channel steel 10. FIG. 7 is a side view showing the welding in FIG. 5.
第７図に示すように、裏あて金がないため、収まりが良

りが良い。As described above, according to this embodiment, the second member 2 with the groove portion 4 formed between it and the slope portion 3 is provided by contacting the first member 1 with the slope portion 3 formed thereon, and the second member 2 is opened. Since the first bead portion 5 is provided on the tip portion 4 and the second bead portion 6 is provided on the opposite side of the first bead portion 5, the width of the contact portion 7 can be appropriately set. Therefore, in the vicinity of the contact portion 7, the weld penetration range during welding of the first bead portion 5 and the weld penetration range during welding of the second bead portion 6 can be made to overlap. Therefore, welding defects are less likely to occur, sufficient welding strength can be obtained without a backing metal, and costs are low.
また、裏はつりが不要なので、作業性が良い。Also, since there is no need to hang the back side, it is easy to work with.
第１の部材１の端面に斜面部３を設け、第２の部材２の
上端部側面と突き当てても良い（第８図）。A sloped portion 3 may be provided on the end surface of the first member 1 and abutted against the side surface of the upper end of the second member 2 (FIG. 8).
この場合、斜面部３を内向きに設けても良い（第９図）
。In this case, the slope portion 3 may be provided facing inward (Fig. 9).
