[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a steel single-opening and double-opening soundproof door.

[0002]

[Prior Art]

 Conventionally, various improvements have been made in soundproof doors in order to improve soundproof performance. One of them is that the opening frame and the door are made of steel, which tries to increase the sound transmission loss by increasing the weight, which is a lightweight door of the aluminum sash. It is known that the soundproofing effect is significantly higher than the soundproofing performance of. At the same time, the structure of the door itself is, of course, a structure with good soundproofing performance, but as a soundproofing property, it is an airtight member to be placed between the opening frame and the door and an airtight member between the summing frames in the case of double doors. Is devised to be. The door structure and soundproofing with airtight materials are also improved in the aluminum sash. As a device for the airtight material, there are shapes, materials and arrangements of the airtight material. It is thought that the soundproofing performance by the shape of the airtight material is conventionally the shape of the airtight material, and importance is attached to the vibration control performance to the mating member that the airtight material contacts when the door is closed. The aluminum sash is provided with multiple fins that come into contact with it. Regarding the material of the airtight material, it is said that an elastomer or the like, which has high self-vibration performance, is used or the rubber hardness is changed. As an example of improving the soundproofing performance by arranging airtight materials, it is performed to double- surround the opening frame, the door, and the assembling frame in the inward and outward directions. In addition, it is also known that the vibration damping performance and the soundproofing performance are improved by arranging one layer around the other layer and arranging the other layer on a part instead of the entire circumference.

[0003]

[Problems to be solved by the device]

 Conventionally, the airtight material provided between the opening frame and the door and the mating member that separates when the door is opened and closed are made of steel.In the case of a soundproof door, a steel plate is press-molded. You are dressed up. In such a state, the airtight material is doubled in the inward and outward directions, and the airtight material is surrounded and arranged, and the shape of the airtight material is modified to improve the soundproofing performance. The arrangement of the airtight material and the change of the shape of the airtight material are accompanied by the change of the sectional shape of the door and the opening frame. In the case of an aluminum sash, these cross-section changes are comparatively easy because the extrusion shape is flexible because it is an extrusion mold material.However, for steel doors, at least the opening frame and at least the cross-sectional outer shape of both doors are A simple shape is desirable in manufacturing. Therefore, changing the arrangement of the airtight material and the shape of the airtight material has much less flexibility than the aluminum sash, and from this point it was difficult to improve the soundproofing performance.

[0004]

[Means for Solving the Problems]

 According to a first aspect of the present invention, in a soundproof door in which multiple airtight members are arranged between the opening frame and the door in the inner and outer directions to close the soundproof door, at least a part of a mating member that comes in contact with the airtight member when the door is opened and closed. Is a soundproof door characterized by a stainless steel plate.

A second aspect of the present invention is a soundproof door in which multiple airtight members are arranged inward and outward between an opening frame and a door and a summing frame of the door, and the airtight member is sealed when the door is opened and closed. It is a soundproof door characterized in that at least a part of a mating member to be separated and contacted is a stainless steel plate.

A third aspect of the present invention is the soundproof door according to the first or second aspect, characterized in that all of the mating members that come into contact with the airtight material when the door is opened and closed are stainless steel plates. Is.

It was confirmed that the soundproofing performance was improved by using stainless steel as the mating member in contact with the airtight material. The reason is that stainless steel makes the shape accuracy and surface roughness of stainless steel significantly better than that of the conventional coating, and the complete adhesion of the airtight material to the stainless steel increases the vibration damping performance. The effective contact area between the coated surface and the airtight material is small due to the fine irregularities on the coated surface, and it is thought that the soundproofing performance of stainless steel is large in contrast.
