この発明は、鉄骨構造物等に用いられるかど継
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 corner joint welded structure used for 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の一部も溶け込ませている。
Conventionally, corner joints have been welded using a backing metal 21, as shown in Figure 11. The throat thickness is the same as the plate thickness of the plate 22 on the abutting side. A part of the back plate 21 is also melted into it.
しかし、これでは、裏あて金２１という別部材
が必要であるため、コストが高くなり、また裏あ
て金２１の収まりが悪いという問題点があつた。 However, this requires a separate member called the backing metal 21, which increases the cost, 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, welded from the front side without using a backing metal,
There is also a method of welding from the back side after hanging it.
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
け込みが十分でなく、溶接強度がでない。 However, this has poor workability. Therefore, if we eliminate the work of lifting the back side, there will be insufficient penetration on the back side, resulting in a loss of weld strength.
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くて収まりが良くかつ裏

In the corner 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.

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, sufficient welding strength can be obtained without a backing metal, and the cost is low and easy to fit.
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。Embodiment An embodiment of the present invention will be described based on FIGS. 1 to 7. In this corner joint welding structure, a first member 1 is provided with a slope portion 3 formed by removing a corner portion of one end, and the first member 1 is brought into contact with the slope portion 3 in a perpendicular state by contacting one end of the first member 1. 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 a second member is provided on the opposite side of the first bead portion 5 across the contact portion 7. A second bead portion 6 is provided.

mm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 vertically connected to the second member 2.
The member 2 is arranged horizontally. First member 1
The end surface of the second member 2 is abutted against the side surface of the upper end. The slope portion 3 is provided facing upward at the upper end of the first member 1, and forms a V-shaped groove portion 4 between it and the end surface of the second member. The contact part 7 is 2
A width of approximately mm or less is ensured (Figure 3).
第２図において、Ａは第１ビード部５の溶接時

接時の溶け込み範囲を示している。 In FIG. 2, A indicates the welding range of the first bead portion 5 during welding, and B indicates the welding range of the second bead portion 6 during welding.
接触部７の幅を２mm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、前記溶け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 part 7 is set to be about 2 mm 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 penetration range, it is better to have a narrower width. This is the result of selecting a width that satisfies both.
なお、接触部７の幅を大きく取り過ぎると、第
３図のように、第１ビード部５と第２ビード部６

強度が得られない。 Note that if the width of the contact portion 7 is made too large, the first bead portion 5 and the second bead portion 6 will be separated as shown in FIG.
The penetration ranges during welding do not overlap, and sufficient welding strength cannot be obtained.
