ている。 A damping steel plate consisting of a metal plate - damping material - metal plate has high vibration damping performance. For example, a sheet material with viscoelasticity such as butyl rubber, asphalt, polypropylene, etc. is pasted on one side of the steel sheet panel, and the sheet material is then covered with metal. It is supported by a restraining layer made of plates, and the metal plates on both sides are fixed together by spot welding or bolting.
しかるに拘束層が基板に固定されていると基板
に対して拘束層が動きにくゝなり制振鋼板本来の
制振効果が失なわれるという問題がある。 However, if the restraining layer is fixed to the substrate, there is a problem in that the restraining layer does not easily move relative to the substrate, and the vibration damping effect inherent to the vibration damping steel plate is lost.

Figure 1-2 shows a state in which the above-mentioned damping steel plate is vibrated and deformed, and the substrate 1 shrinks and the restraining layer stretches, the distance between the substrate 1 and the restraining layer 2 narrows, and the shear deformation of the damping material becomes small. The damping effect decreases over time.

基板１の反りを防ぐことができる。Embodiment FIG. 2 shows a plan view of the vibration damping steel plate of the present invention, in which spot welding is carried out at four locations on a substrate 3 as shown in the figure, and an annular rib 5 is provided around each of the spot welds 4. represents the state of In order to show the shape of the annular rib 5, a cross section taken along the line X--X in FIG. 2 is shown in FIG. 3. Since the restraining layer 3 is easily deformed using the rib portion 6 surrounded by the dotted line of the annular rib 5 as a fulcrum, shearing deformation of the damping material 3 is facilitated.
Warping of the substrate 1 can be prevented.
第４図は他の実施態様を示すもので、スポツト
溶接部４の近くに線状リブ７を設けた例でありそ
の作用は上記の環状リブ５の場合と同様である。 FIG. 4 shows another embodiment, in which a linear rib 7 is provided near the spot weld 4, and its function is similar to that of the annular rib 5 described above.

溶接するとよい。 When fixing the constraining layer 3 provided with the annular ribs 5 or linear ribs 7 as described above to the substrate 1, the portion excluding the damping material 2 as shown in FIG. 3, that is, when there is no welding margin, If the metal plate of the restraining layer 3 is simply welded to the substrate 3, the damping material 2 will be exposed to high heat, deteriorating and burning, and the damping performance may be impaired.
Furthermore, if gas is generated from the damping material when exposed to high heat and leaks to the outside of the steel plate, it is not favorable for the working environment. In order to prevent high heat from being applied to the damping material when such a welding margin is missing, it is recommended to weld using the method shown in FIG. 5.

める必要がある。 In other words, in Fig. 5, A indicates the state of the damping steel plate before welding, and the substrate 1 and the restraining layer 3 usually each have a thickness of
A 0.2 to 1.2 mm steel plate is used. The damping material 2 is made of a viscoelastic material having a thickness of 0.4 to 3 mm, such as asphalt sheet, polypropylene, butyl rubber, etc. In step B, a round bar (or polygonal bar) 8 as shown in the figure is pressed against a predetermined welding site, and a load is applied from above until the substrate 1 and the constraining layer 3 come into close contact. Furthermore, in the next step C, the close contact portion 9 is spot welded. Note that in order to prevent high heat from being transmitted to the damping material 2, the welded area must be kept as narrow as possible.
