本考案は片面溶接用裏当材に関し、特に使用後
の固形裏当材処理が確実かつ簡易である構造の裏
当材に関するものである。[Detailed Description of the Invention] The present invention relates to a backing material for single-sided welding, and more particularly to a backing material having a structure that allows reliable and simple processing of the solid backing material after use.
片面溶接の裏当材としては各種の成分、形状の
固形裏当材、またガラス繊維を中心とした可撓性
を有するテープ状の裏当材等が多く実用化され使
用されている。 As backing materials for single-sided welding, many solid backing materials with various compositions and shapes, flexible tape-shaped backing materials mainly made of glass fiber, and the like have been put into practical use.

ある。 As shown in Fig. 1, the method for attaching these backing materials to the back side of the welding part is to place the backing plate 3 on the back side of the backing material 2 and attach it to the magnet 4 that is attracted to the weld base metals 1 and 1'. There is a method of attaching the backing material 2 by means of a pressing member 6 screwed to the bent connecting rod 5, and a method of attaching the presser metal fitting to the welding base material by welding and driving a wedge between it and the backing member. There is a way to install it.
しかしながら、これらの方法は強固に取付けら
れるが、取付け取はずしが複雑で手間がかかり、
治具の数も多く必要であつて費用も高価となる。 However, although these methods can be installed firmly, installation and removal are complicated and time-consuming.
A large number of jigs are required and the cost is high.

に固形裏当材を溶接母材から取はずす方法があ
る。 As a solution to this problem, as shown in Figure 2 a and b, in the case of a tape-shaped backing material or a partially solid backing material, adhesive is attached to one side of the tape 7, such as A foil, which is wider than the backing material 2. Apply agent 8, attach a backing material to the center, and weld the tape surfaces on both sides to the base material 1,
There is a method in which the solid backing material is attached by adhering to the back surface of the welding material 1', and after welding, the solid backing material is removed from the welding base material together with the tape.

つた。 This method is easy to install and remove, does not take much time, and does not require the preparation of special jigs. However, when welding is performed by attaching a solid backing material to the back surface of the groove of the welding base material using a tape such as A foil coated with adhesive, the back surface of the backing material is heated to a temperature of 800 to 900°C. At high temperatures, the organic adhesive thermally decomposes and changes in quality, weakening its adhesion to the solid backing material. In addition, the adhesive strength of the solid backing material itself weakens due to welding heat, and cracks occur due to thermal distortion.
Therefore, when the backing material is removed from the welding base material after welding is completed, the adhesive tape may peel off from the solid backing material, and the solid backing material may fall onto the work floor, shatter into pieces, and scatter. Part or all of the material may remain stuck to the welding base metal, which not only takes time for post-processing including cleaning, but also poses a problem in terms of the working environment.

のである。 The present invention solves the above-mentioned drawbacks of the conventional technology and further strengthens the bond between the adhesive tape such as A-foil and the solid backing material, thereby making it possible to reliably and easily remove the backing material after welding. The purpose is to

性のシートで構成されるものである。 The gist of this is that the backing material for single-sided welding has a structure in which the backing material is fixed with a metallic connecting member embedded in the solid backing material, and the backing material is further composed of a flexible sheet. .
以下本考案を図面により更に具体的に説明す
る。 The present invention will be explained in more detail below with reference to the drawings.
第３図は本考案のもつとも典型的な構造を例示

である。 FIG. 3 illustrates the most typical structure of the present invention. FIG. 3 shows a solid backing material manufactured by embedding a metal connecting member 10 in advance.
After adhering to the adhesive tape (backing material) 7 made of foil, the tip of the metal connecting member 10 is bent, and the adhesive tape is fixed to the solid backing material to form an integrated backing material.

である。 FIG. 5 also shows that the release paper 9 at both ends of the adhesive tape 7 is peeled off to expose the adhesive 8, and the backing material of the present invention is applied to the groove that is the welded part provided on the welding base materials 1, 1'. FIG. 3 is a perspective view showing the attached state of use in more detail.

更に、溶接により粘着テープ７の温度が上昇し、
粘着剤の接着力が劣化しても固形裏当材２と粘着
テープ７は、金属製連結部材１０で固接されてい
るため、容易に両者は分離しない。 As is clear from FIGS. 3 and 5, the backing material of the present invention is bonded to the adhesive tape using the adhesive material 8 and the metal connecting member 10.
Furthermore, the temperature of the adhesive tape 7 increases due to welding,
Even if the adhesive force of the adhesive deteriorates, the solid backing material 2 and the adhesive tape 7 will not be easily separated because they are firmly connected by the metal connecting member 10.
このように固形裏当材２と粘着テープ７の接合
が強化されたため、溶接後裏当材を溶接母材から
取りはずす作業も、粘着テープを剥離すること
で、固形裏当材と分離することなく、簡単かつ完
全に行なうことが出来る。 Since the bond between the solid backing material 2 and the adhesive tape 7 has been strengthened in this way, the work of removing the backing material from the welding base material after welding can be done without separating it from the solid backing material by peeling off the adhesive tape. , can be easily and completely performed.

１０で柔軟性シートを固定した裏当材を示す。 In the case of the method of attaching the backing material to the welding base materials 1 and 1' using the magnet 4 using the pressing member 6 as shown in FIG. 1, the solid backing material and the flexible sheet are attached as shown in FIG. By using the backing material of the present invention, in which the backing material is joined with a metallic connecting material, the processing of the backing material after welding can be carried out easily, reliably and safely in the same way as when using adhesive tape as described above. I can do it. That is, in FIG. 4, a metal connecting member 10 is embedded in a solid backing material 2, and asbestos 11 and corrugated cardboard 12 are embedded.
A backing material is shown in which a flexible sheet is constructed by laminating the flexible sheets, and the flexible sheet is fixed by the connecting member 10.

ず取扱いが簡単である。 Asbestos 11 and cardboard 12 are connecting member 1
Since it is fixed to the solid backing material at 0, even if the pressing member 6 is removed, the solid backing material will not separate from the backing material due to welding heat, and will not break even if subjected to thermal distortion, making it easy to handle. It is.

を裏打材と一諸に取りはずすことができる。 Since the present invention is constructed as described above, the integration between the solid backing material and the backing material such as A-foil adhesive tape or glass fiber tape is strengthened, and the bonding force effect does not deteriorate even after welding work. Since there is no
After welding, the solid backing material can be easily and reliably removed together with the backing material without scattering around the work floor or sticking to the welding base material.
