本考案はＴ型、Ｌ型鋼等の水平部材と垂直部材
が複合された部材の水平、垂直部材の交叉部に適
用する片面溶接用裏当材に関する。[Detailed description of the invention] (Technical field of the invention) This invention is a backing material for single-sided welding that is applied to the intersection of horizontal and vertical members of a composite member such as T-shaped and L-shaped steel. Regarding.

当材が多用されている。(Prior Art) Generally, when constructing structures by welding in shipbuilding, architecture, bridges, etc., double-sided welding is often impossible. For this reason or for the purpose of saving labor in the welding process, single-sided welding is widely practiced. In this single-sided welding, a backing material is used to form a uranami beat, but as a simple single-sided welding backing material, a solid backing material made of lightweight short material or a tape backing material made of glass fiber can be used. It is widely used.

裏当材は、全体として長手方向に可撓性を有する
ことから曲面状の被溶接面であつても適応できる
利点がある。 The present invention relates to an improvement of a solid backing material in which tile-shaped solid backing materials are continuously arranged in the longitudinal direction and adhered to a tape. Since this backing material has flexibility in the longitudinal direction as a whole, it has the advantage that it can be applied even to curved surfaces to be welded.

5958号公報あるいは実開昭56−29696号公報で開
示されたもの等があるが、いずれも開先線全体に
曲りを有して、曲率が大きい箇所に適用するもの
である。 As a conventional backing material of this type,
There are those disclosed in Japanese Utility Model Publication No. 5958 and Japanese Utility Model Application Publication No. 56-29696, both of which have a bend in the entire groove line and are applied to areas with large curvature.
これらの裏当材は、Ｔ型、Ｌ型鋼等の水平部材

有する部材の該小曲率の開先箇所に適用すること
はできず、このような箇所に使用する裏当材とし
ては、該箇所の小曲率に合わせて、曲面状に形成
した裏当材を使用していた。 These backing materials are part of the groove line (the intersection of the horizontal member and the vertical member) of a member that has a bend, such as a member that is a composite of a horizontal member and a vertical member such as T-shaped and L-shaped steel. It cannot be applied to grooves with small curvature, and the backing material used for such places is a backing material formed into a curved surface to match the small curvature of the part. .
例えば水平部材（フランジ部）用の裏当材の一
端を、交叉部に合せて曲面状にしたもの、さらに
他端も曲面状にして、裏当材を裏返して２回使用
できるようにしたもの等がある。 For example, one end of a backing material for a horizontal member (flange part) is curved to match the intersection, and the other end is also curved so that the backing material can be turned over and used twice. etc.
ところが、このような曲率が決められた裏当材
であると、裏当材の曲率に一致する開先にしか使
用できず、開先の曲率に合わせて多種類の裏当材
を用意しなければならず不便であつた。 However, such a backing material with a fixed curvature can only be used for grooves that match the curvature of the backing material, and many types of backing materials must be prepared to match the curvature of the groove. It was definitely inconvenient.

接用裏当材を提供することを目的とする。(Purpose of the invention) The present invention solves the drawbacks of the prior art, and has a simple structure that allows flexible opening according to the groove curvature at the intersection of a composite member consisting of a horizontal member and a vertical member. It is an object of the present invention to provide a backing material for single-sided welding, in which the curvature of the surface that comes into contact first changes and can sufficiently cope with changes in the curvature of the intersecting portion.

以下本考案を図面に示す具体例により説明する
が、もとより下記の具体例は、本考案を限定する
ものではなく、適宜本考案の主旨を逸脱しない範
囲で、色々な態様が考えられる。 The present invention will be described below with reference to specific examples shown in the drawings, but the following specific examples do not limit the present invention, and various modifications can be made without departing from the gist of the present invention.
第１図ａは本考案の具体例の全体斜視図、同図
ｂはその側面図である。 FIG. 1a is an overall perspective view of a specific example of the present invention, and FIG. 1b is a side view thereof.

れによりはくりが容易になる。 Reference numeral 1 designates a backing block such as a ceramic heat-resistant tile constituting the backing material 10, which has a recessed portion for receiving slag in the direction of the central groove line on its surface (the surface in contact with the groove). 2 is a flexible heat-resistant material, for example A, for attaching the backing block to the back surface of the groove of the material to be welded.
This is a tape for attaching a backing material made of foil, and is configured to be wider than the backing block 1. The tape 2 is coated with adhesive on one side, backing blocks 1 are continuously lined up and pasted in the direction of the central groove line, and peeling tape 3 is pasted on both ends to be peeled off when using the backing material. . As shown in the figure, the peeling tape is preferably attached to the tape 2 so that a portion thereof protrudes, thereby making it easier to peel off.

る。 As shown in FIG. 1b, the backing block 1 of the backing material has a fan-shaped side cross section, the circular arc surface 4 on the outer periphery is in contact with the back surface of the groove, and the bottom part 5 in the center is attached to the tape 2. . In this pasting state, as shown in the figure, the bottom portions 5 of each block 1 are pasted at predetermined intervals.

裏当材を取付けることができる。 That is, by attaching the bottom portions 5 of each block to the tape 5 at predetermined intervals in this way, play is provided, and this play changes the curvature of the outer periphery of the backing material in accordance with the curvature of the groove of the material to be welded. This makes it possible to fully fit the back side of the groove,
A backing material can be attached.
第２図ａ，ｂは、第１図に示す具体例の裏当材

用した状態を示す図である。 FIGS. 2a and 2b are diagrams showing a state in which the backing material of the specific example shown in FIG. 1 is applied to the intersection portions of L-shaped steel having different curvatures at the intersection portions.

する裏当材である。 The curvature of b is slightly larger than that of a, but in either case, the backing material is in good contact with the back surface of the groove.
1, a composite member consisting of vertical members 6-2, 8, 8
-1 is the backing material of the members 6-1 and 6-2, respectively,
0 is a backing material applied to the intersection of members 6-1 and 6-2 of the present invention.

ープ２から外してもよい。 In this case, since three of the four blocks 1 of the backing material 10 cover the intersection groove,
The remaining one is used as a backing material for the horizontal member 6-1. Of course, since one block is not used as a backing material for the intersection groove, it may be removed from the tape 2.

All four blocks 1 are used, and as shown in the figure, the bottoms 5 of each block 1 are spaced apart to accommodate the groove curvature of the intersection.

る。 In the above specific example, as the heat-resistant backing block constituting the backing material, a fan-shaped block with a cross-sectional shape of about 30 degrees is used, and four of these are used as the backing material mounting tape, so that the distance between the bottoms of the blocks is approximately the same. Although the blocks are pasted so as to have the width at the bottom, the present invention is not limited to this, and it is clear that the angle, number, interval between the blocks, etc. of the blocks can be changed as appropriate depending on the manner of use.
いずれにしても、ブロツクの角度を小さく、か
つブロツク底部の間隔を大きくすることによつ

なものとなる。 In any case, by reducing the angle of the blocks and increasing the distance between the block bottoms, the degree of adaptation to changes in the curvature of the groove becomes greater.

として最適なものといえる。(Effect of the invention) As described above, if the backing material for single-sided welding of the present invention is used, the curvature of the surface in contact with the groove of the backing material can be adjusted to match the curvature of the intersection of the composite member that is the material to be welded. It is possible to attach the backing material by sufficiently fitting it to the back surface of the groove, and as a result, the slag retention function becomes good and an excellent uranami bead can be obtained. Moreover, since it has a simple structure, it is easy to process. The present invention can be said to be optimal as a backing material to be applied to the intersections of composite members.
