にパテを塗り、該パテの養生後に表面仕上げ塗装
をしなければならなかつた。 Conventionally, as a method for connecting the front and back plates of a steel door, a connecting member is interposed between the front and back plates, and the front plate and the connecting member and the back plate and the connecting member are respectively fixed by arc welding from the outside of the front and back plates. There is a method in which the outer surfaces of the front and back plates are melted at the welded part, so it is not possible to directly apply a surface finish coating to the outer surfaces while they are still in the welded state. Therefore, it was necessary to grind the outer surface of the welded part after welding, apply putty, and apply a surface finishing coat after curing the putty.
そのため、表面仕上げに非常に手間を要する上
に、該溶接部のみパテが有することから、該部が
経年によつて他の部分と比較して変色し、ドアー
表面の美観が損なわれる欠点があつた。 Therefore, it takes a lot of effort to finish the surface, and since the putty is applied only to the welded area, this area has the disadvantage that it discolors compared to other areas over time, impairing the beauty of the door surface. Ta.

とするものである。 The present invention focuses on the fact that when stud bolts are welded to the back side of the base metal using stud welding, the surface of the base metal will not be distorted or the paint or coating on the surface will not be burnt out. The object of the present invention is to propose a device that can connect the front and back panels of a door using the method, and to solve the above-mentioned conventional drawbacks. That is, in the present invention, a connecting member 3 is welded and fixed to the inner surface of the back plate 2 to interpose between the front and back plates 1 and 2 and connect them at an appropriate interval, and the front plate 1 of the connecting member 3 is fixed to the inner surface of the back plate 2. An engaging member 5 having an engaging hole 4 penetrating in the front and back directions is provided on the side portion, and a portion of the inner surface of the top plate 1 located in the engaging hole 4 is inserted into the engaging hole 4. A cotter pin 6 having a diameter and having a hollow tip is fixed to the top plate 1 by stud welding, and is inserted into the engagement hole 4 between the inner surface of the back plate 2 and the engagement hole 4. The present invention is characterized in that it includes a wedge 7 that expands the tip of the cotter pin 6 to a diameter larger than the diameter of the engagement hole 4 inside the engagement member 5.

圧拡開するようになつている。 Next, an embodiment of the present invention shown in the drawings will be described. 1 and 2 are front and back plates made of steel, and 3 is a connecting member made of C-shaped steel in cross section, one side of which is fixed to the inner surface of the back plate 2 by welding 8, and an engaging member on the inside of the other side. 5 is fixed by welding. Reference numeral 4 denotes an engagement hole formed through the other side and the engagement member 5 in the front and back directions. A steel split pin 6 is fixed by stud welding to a portion of the inner surface of the top plate 1 located in the engagement hole 4. The split pin 6 has a diameter smaller than the inner diameter of the engagement hole 4, a total length longer than the entire length of the engagement hole 4, and a hollow tip portion with a plurality of split grooves 6a in the axial direction on its peripheral wall. It is formed by engraving. Reference numeral 7 denotes a pin-shaped wedge, which is interposed between the side of the front plate side of the connecting member 3 and the engaging member 5, and the tip of the connecting member 5 side has a smaller diameter than the hollow part of the split pin 6. A stepped portion 7a having a larger diameter than the inner diameter of the hollow portion is formed at a position toward the base of the hollow portion, and by press-fitting the tip portion into the tip portion of the split pin 6 protruding from the engagement hole 4, The tip of the split pin 6 is pressed and expanded outward from the engagement hole 4 by the stepped portion 7a.

れる。 As described above, in order to assemble the front and back plates 1 and 2, place the back plate 1 on a workbench or the like, and insert the wedge 7 into the engaging hole 4 by inserting the tip of the wedge 7 having the step 7a into the engagement hole.
After inserting it into the hole 3a, insert the protrusion 7b provided at the base into the hole 3a.
Put it inside and stand up. Next, the front plate 1 is pressed toward the back plate 2 with the split pin 6 inserted into the engagement hole 4. As a result, the tip of the split pin 6 becomes wedge 7.
The stepped portion 7 a presses the engaging hole 4 to expand it wider than the inner diameter thereof, and the expanded portion engages the engaging member 5 . Therefore, the split pin 6 is firmly prevented from coming off, and as a result, the front and back plates 1 and 2 are firmly assembled.

る。 As described above, according to the present invention, only the split pin 6 is required for welding to the top plate 1, and the split pin 6 only needs to be welded to the top plate 1.
Since this can be done by stud welding, there will be no distortion or damage to the surface of the top plate. Therefore, there is no need for grinder finishing or putty coating, which is done after conventional arc welding, and surface finish painting can be done immediately.There is also no discoloration of the finish coating due to conventional putty, and the beauty of the surface of the top plate can be maintained for a long time. It has the advantage that it can be maintained for a long time.
