Description

[0001] The present invention relates to a ceiling bracket for a ceiling material for reducing interlayer noise, and a ceiling system including the ceiling bracket. [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a lattice bracket for a ceiling material, and more particularly, to a ceiling bracket for ceiling material for reducing noise in a floor so as to reduce interlayer noise in materials and components constituting the ceiling system, and a ceiling system using the same.

As the inter-floor noise problem between the upper and lower generations of the apartment complex has become a social issue, efforts to develop various systems to solve this problem have been continuing.

The suppression of interlayer noise is mainly used to improve the floor system or improve the ceiling system. There is a difficulty in securing economical efficiency because the floor system which has a relatively good sound insulation performance relative to the ceiling system has a large performance difference depending on the cost.

Ceiling systems are, for example, wood framed structures and lightweight framed structures. Both structures are used to fix the slabs and ceiling materials (gypsum boards) using hangers or lanterns.

Wooden frames have been used for a long time by making frames using wooden blocks and attaching ceilings, but due to the inherent characteristics of wood such as the price of wood, the weakness of moisture, the occurrence of insects and the smell caused by fungi Usage is gradually decreasing.

The lightweight frame structure is lightweight steel represented by M-bar, which is widely used for general office space rather than residential space. However, it is increasingly used in residential space instead of wooden frame. However, there is a technical problem to solve the low ceiling height for the lightweight steel ceiling frame to be used in the residential apartment. Especially, the ceiling portion of the living room or the kitchen is hardly installed on the ceiling.

Generally, the floor impact sound generated in the upper generation is transmitted to the lower generation through the floor (ceiling in the lower generation) and the wall. In the conventional ceiling system, the solid sound transmitted is not blocked or amplified, There was a case that it infringed comfortable residence right. Accordingly, there is an increasing need to develop a ceiling system in which a lower-generation resident can actively intercept the interlayer noise or a component used therein.
