Description

Antivibration Moon Bracket with Bending Plate Spring and Vibration Ceiling Using It {Plate Spring for Isolation from Floor Vibration and Vibration Isolating Ceiling using such Plate Spring}

The present invention relates to a dustproof ceiling for preventing vibration from being transmitted from the floor slab to the ceiling panel to prevent the occurrence of a floor shock sound, and a dustproof bracket for the same. Specifically, a ceiling using a lightweight steel frame on the bottom surface of the floor slab In installing the ceiling with the ceiling surface of the room by installing the panel, the vibration between the floor slab and the ceiling panel is prevented from transmitting the vibration from the floor slab to the ceiling panel while maintaining a small gap between the floor slab and the ceiling panel. The present invention relates to an anti-vibration stand bracket made of a bent leaf spring and to an anti-vibration ceiling constructed by using the same.

In general, the ceiling structure formed by installing the ceiling surface on the bottom surface of the floor slab has a wooden structure and a light steel frame structure, all of which are fixed between the floor slab and the ceiling panel or by using a hanging rod. That's the way. The ceiling surface of the wooden structure is made of wood frame, and the ceiling panel is attached to the ceiling frame by attaching a ceiling panel such as gypsum board. Vulnerable, due to the disadvantages such as odor caused by the habitat and fungus of insects, the ceiling structure by the neck structure is gradually decreasing use.

On the other hand, the ceiling surface of the light steel frame structure, the ceiling frame to be attached to the ceiling panel is formed by using a steel frame of light steel steel including an M-bar (M-bar). In the past, it was used to form ceilings in general office spaces with high floors, but it is increasingly used as an alternative structure of wooden ceiling frames in multi-unit houses such as apartments.

In constructing the ceiling of such a light steel frame structure, a technique for minimizing the vibration transmitted from the floor slab to the ceiling surface has been proposed to reduce the floor impact sound caused by the impact on the floor slab. In the Japanese Patent Application No. 2001-0057969, a ceiling system having a light steel frame structure that absorbs floor impact sound has been proposed under the name of the invention "ceiling system that absorbs floor impact sound of a steel frame type building".

According to the ceiling system of the conventional lightweight steel frame structure, between the hanger bolt and the hanger clip included in the lightweight steel frame to suppress the vibration caused by the impact to reduce the transmission of shock, and also to install the ceiling of the ceiling By attaching a sound absorbing material to the inside of the finish panel to absorb the noise generated in the inside of the half band, and installing a sound absorbing film to absorb the noise in the low frequency region between the hanger bolts. It is implemented to absorb floor impact sound. The conventional lightweight steel frame ceiling system has a structure that maintains a relatively large gap between the floor slab and the ceiling surface by a relatively long hanger bolt, and is designed to maintain a very large gap between the floor slab and the ceiling surface. This can be useful for ceilings (i.e. ceilings designed to keep the space between the floor slab and the ceiling very large), but the spacing between the floor slab and the ceiling surface, such as the ceiling of a well in a living room or kitchen, such as an apartment. There is a problem in that it is not applicable to a ceiling designed to keep the space very small (ie, a ceiling designed to keep the space between the floor slab and the ceiling surface very small).

In addition, the above-described conventional lightweight steel frame ceiling system has a problem that the facility for blocking the floor impact sound is very complicated and the economical efficiency of the facility for the floor impact sound blocking is reduced.
