Abstract

(57) [Abstract] [Purpose] An object of the present invention is to provide a structure for damping vibration of a ship floor, which is lighter in weight than the conventional structure of a ship floor and which is excellent in vibration damping effect and adhesion control. . [Structure] 1 is a steel plate floor, 2 is a damping material made of a viscoelastic material such as rubber or plastic, 3 is a deck composition (a mixture of latex and silica sand in cement), and A steel plate 5 having a constant thickness is interposed between the deck composition 3 and the deck composition 3 with an adhesive 4. Further, the steel plate floor 1 and the vibration damping material 2 are bonded together via an adhesive 6.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a vibration control structure for a ship floor, and more particularly to a vibration control structure that is lightweight and has excellent vibration control effect and adhesion control.

[0002]

[Prior art]

 Conventionally, as a vibration control structure for a ship floor, for example, as shown in Fig. 3, a plate with a thickness of about 2 mm is formed on a steel plate floor 1 with a thickness of about 5 mm and made of a viscoelastic material such as rubber or plastic. The formed damping material 2 was laminated, and on top of that, a deck composition 3 (a mixture of cement and latex and silica sand) having a thickness of about 15 mm to 20 mm was laminated.

[0003]

[Problems to be solved by the device]

 However, in the conventional vibration damping countermeasure structure as described above, the thickness of the deck composition 3 is made thick in order to improve the vibration damping effect. There was a problem saying that there is no. Further, since the adhesion between the damping material 2 and the deck composition 3 is poor, the interface between the deck composition 3 and the damping material 2 easily peels off, and there is a problem in durability.

The present invention has been made in view of such conventional problems, and is lighter than the structure of a conventional ship floor, and is also a vibration suppressor for a ship floor excellent in vibration damping effect and adhesion control. The purpose is to provide a countermeasure structure.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the idea of the present invention is to interpose a steel plate having a constant thickness between a damping material and a deck composition via an adhesive.

[0006]

The present invention is constructed as described above, and a steel plate having a constant thickness is interposed between the damping material and the deck composition, and these members are bonded by an adhesive. However, it is possible to reduce the weight without making the deck composition thicker as in the past, and also by adhering the steel plate, the damping material, and the deck composition via adhesives respectively, the adhesive force is also improved. It is strong and the vibration damping effect can be enhanced more than before.

[Example of device]

 An embodiment of the present invention will be described below with reference to the accompanying drawings. The same components as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted. Fig. 1 is a cross-sectional view of a ship floor in which the present invention has been implemented. 1 is a steel plate floor, 2 is a damping material made of a viscoelastic material such as rubber or plastic, and 3 is a deck composition (in the cement). A mixture of latex and silica sand) is shown, and a steel plate 5 having a constant thickness is interposed between the damping material 2 and the deck composition 3 with an adhesive 4 interposed therebetween. Further, the steel plate floor 1 and the damping material 2 are adhered to each other via an adhesive 6.

In an embodiment of the present invention, a plate-shaped damping material 2 made of a viscoelastic material such as rubber or plastic and having a thickness of about 2 mm is laminated on a steel plate floor 1 having a thickness of about 5 mm, Furthermore, a steel plate 5 (SS41) having a thickness of 1 mm is adhered on it via an adhesive 4, and a deck composition 3 having a thickness of about 8 mm (a mixture of cement and latex or silica sand) Are stacked.

As described above, by interposing the steel plate 5 having a thickness of 1 mm between the damping material 2 and the deck composition 3, the thickness (15 mm, 20 mm) of the conventional deck composition 3 is reduced. Te, can have a thickness of about 8 mm, thereby, those as a vibration countermeasure by weight (m ² weight excluding floor), the thickness of the conventional deck composition 3 cases of 15 mm, was 30kg However, it can be reduced by about 14%, and when the conventional deck composition 3 has a thickness of 20 mm, it can be reduced by about 32% from 38.4 kg.

Further, as shown in FIG. 2, as a damping effect, the loss coefficient of the damping material 2 with respect to temperature (° C.) can be remarkably improved as compared with the conventional deck composition 3. Is.

[Effect of the device]

 In this invention, as described above, since a steel plate having a certain thickness is interposed between the damping material and the deck composition via an adhesive, the structure is lighter than the conventional structure of the ship floor, and the damping material is also reduced. It has excellent effects and adhesiveness, and has an effect that it can be manufactured at low cost.
