本願考案は、自動車等の防音用として使用する制振鋼板の溶接構造に関する。 The present invention relates to a welded structure of a vibration damping steel plate used for soundproofing an automobile or the like.

【０００２】[0002]

【従来の技術】[Prior Art]

自動車等におけるパネルの振動によるノイズの発生を防ぐ手段の一つとして、パネル間に制振材を介在せしめた制振鋼板、例えば薄板鋼板の中間に樹脂材を挟んだものを使用し、振動の減衰能を高めて振動を小さくする方法がある。 As one of the means to prevent the generation of noise due to panel vibration in automobiles, etc., use a vibration-damping steel plate with a vibration-damping material interposed between the panels, such as a thin steel plate with a resin material sandwiched in between There is a method to increase the damping capacity of and reduce the vibration.

【０００３】そして、このような制振鋼板同士の溶接構造として、従来は、図５に示すように、制振鋼板１（薄板鋼板２の中間に樹脂材３を介在させたもの）の接続端部４を夫々直角に折曲げてＬ字状に形成せしめ、該接続端部４，４を面接せしめるとゝもに、両制振鋼板１，１の接続端部端面５，５の部分を溶接６して接続した構造のもの（へり溶接）と、図６に示すように、一方の接続端部４Ａをこれと接続する他方の接続端部４Ｂより長く突出せしめて両接続端部４Ａ，４Ｂを重ね合わせ、短い他方の前記接続端部４Ｂの接続端部端面５Ｂの部分において、長い一方の接続端部４Ａと溶接７して接続した構造のもの（重ね溶接）とがある。As a welding structure for such damping steel plates, conventionally, as shown in FIG. 5, a connection end of a damping steel plate 1 (a thin steel plate 2 with a resin material 3 interposed in the middle) is connected. Each part 4 is bent at a right angle to form an L-shape, and the connecting ends 4 and 4 are brought into face-to-face contact with each other. Also, the connecting end parts 5 and 5 of both damping steel plates 1 and 1 are welded. As shown in FIG. 6, one connecting end portion 4A is made to project longer than the other connecting end portion 4B connected thereto, and both connecting end portions 4A, 4A, There is a structure (lap welding) in which 4B is overlapped and connected by welding 7 to one of the long connecting ends 4A at the connecting end 4B of the other short connecting end 4B.

【考案が解決しようとする問題点】[Problems to be solved by the device]

しかしながら、図５に示すような従来の溶接構造のものは、普通鋼板の場合は容易に溶接できるが、制振鋼板１では中間に樹脂材３を挟んだ構成であるため、溶接の際の熱により接続端部４，４の部分の樹脂材３が溶融するとゝもに、該接続端部４，４における最外側の薄板鋼板２Ａ，２Ａには熱伸長によって互いに離反する方向の力が発生する。その結果、最外側の薄板鋼板２Ａ，２Ａが接続端部端面５，５の部分から反り返り、口開きが生じて溶接不良となるといった欠点がある。また、図６に示すような従来の溶接構造のものは、前記と同様な原因により、長い方の最外側の薄板鋼板２Ａがその接続部端面５Ａ部分から反り返り、前記と同様な口開きが生じて、溶接不良となるといった欠点がある。 However, the conventional welding structure as shown in FIG. 5 can be easily welded in the case of the ordinary steel plate, but since the vibration-damping steel plate 1 has the resin material 3 sandwiched in the middle, the heat of welding As a result, when the resin material 3 at the connection end portions 4 and 4 is melted, a force is generated in the outermost thin steel plates 2A and 2A at the connection end portions 4 and 4 in a direction in which they separate from each other due to thermal expansion. To do. As a result, there is a drawback that the outermost thin steel plates 2A, 2A are warped from the end faces 5, 5 of the connection end portions, resulting in open mouth and poor welding. Further, in the case of the conventional welded structure as shown in FIG. 6, due to the same reason as above, the longer outermost thin steel plate 2A is warped from the end face 5A of the connecting portion, and the same mouth as described above is produced. There is a drawback that a gap is generated and a welding failure occurs.

【実施例】【Example】

以下、本考案を図１乃至図４に示す実施例に基き詳細に説明する。なお、図１は考案に係る溶接構造の断面図で、図２は同溶接構造の加工工程を示す説明図、図３及び図４は本考案の他の実施例の断面図である。 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in FIGS. 1 is a sectional view of a welding structure according to the present invention, FIG. 2 is an explanatory view showing a processing step of the welding structure, and FIGS. 3 and 4 are sectional views of another embodiment of the present invention.

【０００７】図１乃至図３において、１０は制振鋼板で、表裏２枚の薄板鋼板１１・１１の間に樹脂材１２を挟み一体構造としたものであり、該両制振鋼板１０の接続端部１３，１４をそれぞれ外方に直角に折曲するとゝもに、その接続端部１３，１４を互いに面接せしめてある。In FIGS. 1 to 3, reference numeral 10 denotes a vibration damping steel plate, which has a structure in which a resin material 12 is sandwiched between two front and back thin steel plates 11 and 11 and the vibration damping steel plates 10 are connected to each other. When the ends 13 and 14 are bent outward at a right angle, the connecting ends 13 and 14 are in contact with each other.

【０００８】１３Ａは上位に位置する接続端部１３の端面で、図２の（イ）に示すように、下位に位置する接続端部１４の途中まで延びており、該接続端部１４の延出部分を、同図（ロ）に示すように、前記接続端部１３の端面１３Ａの部分で上方に折り返し、同図（ハ）に示すように、接続端部１３を内部に抱持した状態に形成するとゝもに、両接続端部１３，１４部分をかしめて連結している。Reference numeral 13 A denotes an end face of the upper connecting end 13, which extends to a midpoint of the lower connecting end 14 as shown in FIG. The projecting portion is folded back upward at the end surface 13A of the connecting end portion 13 as shown in FIG. 2B, and the connecting end portion 13 is held inside as shown in FIG. When it is formed in such a state, both connecting end portions 13 and 14 are caulked and connected to each other.

【０００９】１５は溶接金属で、図１に示す実施例では、前記接続端部１４の端面１４Ａの部分で溶接したものであり、また図３に示す実施例では、前記両接続端部１３，１４の合わせ部分１６を溶接金属１５で溶接したものである。Reference numeral 15 is a weld metal, which is welded at the end face 14 A of the connecting end portion 14 in the embodiment shown in FIG. 1, and in the embodiment shown in FIG. The mating portion 16 of 14 is welded with the weld metal 15.

【００１０】而して、図１に示す実施例のものでは、接続端部１４の端面１４Ａの部分で溶接するため溶接金属１５の乗りもよく、該端面１４Ａの全部が溶接金属１５で被覆されることになり、口開きが生じることなく溶接できる。また、図３に示す実施例においては、接続端部１４の端面１４Ａから離れ、且つ制振鋼板１０の裏側における両接続端部１３，１４の合わせ部分１６で溶接するため、溶接時における接続端部１４の端面１４Ａ近傍への熱の伝導もなく、前記実施例の場合と同様に、口開きが生じることなく溶接できる。Therefore, in the embodiment shown in FIG. 1, the weld metal 15 can be mounted on the connection end portion 14 because the welding is performed at the end surface 14 A of the connection end portion 14, and the entire end surface 14 A is covered with the weld metal 15. As a result, welding can be performed without opening the mouth. Further, in the embodiment shown in FIG. 3, the welding is performed at the joining portion 16 of the connecting end portions 13 and 14 on the back side of the damping steel plate 10 apart from the end surface 14A of the connecting end portion 14, and therefore, it can be performed at the time of welding. There is no conduction of heat to the vicinity of the end face 14A of the connecting end portion 14, and welding can be performed without opening the mouth, as in the case of the above-described embodiment.

【００１１】図４に示すものは、本考案の更に別の実施例で、接続する両制振鋼板１０の接続端部１３，１４を互いに反対方向に折り返してＵ字状に屈曲せしめ、該Ｕ字状の接続端部１３，１４を互いに係合せしめる。そして、接続端部１３，１４の部分を両制振鋼板１０の外側からかしめて接続するとゝもに、接続端部１４の屈曲部と他方の制振鋼板１０との合わせ部分１６Ａを溶接金属１５で溶接したものである。FIG. 4 shows another embodiment of the present invention in which the connecting end portions 13 and 14 of both damping steel plates 10 to be connected are folded back in opposite directions and bent in a U shape. The U-shaped connecting ends 13, 14 are engaged with each other. Then, when the connecting end portions 13 and 14 are caulked from the outside of both damping steel plates 10 to connect, the joint portion 16A between the bent portion of the connecting end portion 14 and the other damping steel plate 10 is welded to the weld metal. It was welded at 15.

【００１２】而して、接続端部１３，１４の端面１３Ａ，１４Ａは、夫々互いに接続端部１３，１４で抱持された状態で連結されているため、溶接時における熱の影響を受けることがなく、口開きが生じることなく溶接できる。Since the end faces 13A and 14A of the connection end portions 13 and 14 are connected to each other while being held by the connection end portions 13 and 14, they are affected by heat during welding. It can be welded without cracking and opening.
