Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for efficiently and economically manufacturing a damping plate used for a structural member of a stairway installed in a building, a factory, a home or the like by rolling.

[0002]

2. Description of the Related Art Striped steel plates with a striped pattern to prevent slippage are used on the surface of metal plates, which are structural members of stairs for elevating stairs installed outside or inside buildings, factories, homes, etc. It is often done.

However, although the striped steel plate can prevent slippage to some extent, it has a problem in vibration damping property, and from the viewpoint of anti-slip / vibration property, plastic is put on the upper surface of the metal plate or slippage is prevented at the tread edge of the stairs. I was adding parts.

From the viewpoint of corrosion resistance, the metal plate was coated with paint to improve the corrosion resistance, but the durability was not sufficient.

[0005]

The present inventor has applied for the above problems by inventing a staircase excellent in vibration damping property and non-slip property by using a vibration damping plate as a structural member. However, the stairs are formed by forming a groove and a striped pattern on the surface of a vibration damping plate which is a structural member in order to impart vibration damping property and anti-slip, and it requires a great deal of manpower to manufacture the stairs, and the manufacturing cost is also high. It was big. An object of the present invention is to economically manufacture a vibration damping plate which is a structural member of the stairs.

[0006]

In rolling manufacturing of a stair damping plate according to the present invention, one roll of a pair of rolling rolls used for rolling is provided with one of the rolling rolls. A plurality of groove portions are formed in an annular shape in a part, and a striped pattern is formed adjacent to the groove portions, and an economical vibration damping plate for stairs is obtained by continuously rolling a plate-shaped long material. It is a manufacturing method.

That is, the present inventor uses a rolling roll as a method for manufacturing the above-mentioned stair damping plate, forms a striped pattern on substantially the entire outer peripheral surface of the rolling roll, and also uses the rolling roll. If the damping plate for stairs is rolled using a rolling roll in which a groove is formed at a position corresponding to the edge of the stair tread on the outer peripheral surface of, the tread of the structural member of the stair in one rolling The present invention has been completed based on the idea that the striped steel plate portion and the non-slip portion of the tread edge portion can be formed, the productivity is efficient, and the stair damping plate can be economically manufactured.

A staircase using the damping plate manufactured by the method of the present invention is composed of a metal plate as a structural member, and is a metal plate having substantially the same thickness as the metal plate. A staircase characterized by using a rivet or the like as a joining member for joining the structural plate and the damping plate, and the vibration damping plate superposed on the metal plate for suppressing the noise generated when going up and down. It has an effect.

Further, the present inventor has found that the structural member of the stairs is
Focusing on the fact that they vibrate at unique frequencies depending on the material and shape, but do not vibrate periodically if the structure is not integral,
By dividing this structural member into several members and joining them as a damping plate, it was found that vibration energy can be exerted by absorbing vibration energy as friction energy at this joint part, and to use for this The present invention has been made based on the idea that the stair damping plate can be efficiently and economically manufactured by devising a rolling roll for rolling the stair damping plate.

As the metal plate used in the present invention, stainless steel, copper, aluminum or the like can be used. Further, if the joint surface between the structural member and the vibration damping plate is processed into a rough surface, the vibration damping property is increased. As a method for realizing this, for example, a rolling roll which is a pair of the rolling rolls is used. The purpose can be achieved by carving a rough caribean on the outer peripheral surface of.
