KR102223415B1 - Ceiling corner bass trap for reduction of floor impact sound - Google Patents

Abstract

The present invention relates to a ceiling corner bass trap for reducing noise between floors. According to an embodiment of the present invention, the ceiling corner bass trap for reducing noise between floors can effectively reduce sound by absorbing low-frequency heavy impact sound transmitted through a ceiling and a wall of a multi-family house such as an apartment and the like. In addition, sound of low-frequency band (63 Hz band) can be reduced by supplementing an existing floor cushioning material and a sound absorbing material which can reduce sound of only 125 Hz or higher, and it is easy to work compared to floor reinforcement which takes a lot of time and money. Moreover, since the ceiling corner bass trap for reducing noise between floors can be packaged and manufactured in a factory in a form of a prefab, it is easy to perform field installation work. In addition, workability can be secured by avoiding interference with installations such as ventilation ducts, cold and hot water pipes and the like installed in a corner of the ceiling.

Description

Ceiling corner base trap for floor noise reduction {CEILING CORNER BASS TRAP FOR REDUCTION OF FLOOR IMPACT SOUND}

The present invention relates to a ceiling corner base trap for reducing inter-floor noise, and more specifically, a corner base trap in which a porous sound absorbing material and a metal plate are stacked on the ceiling slab and the upper part of the wall (the ceiling corner part) is installed to reduce the floor impact sound. It can be packaged and manufactured in the factory in the form of a prefab, and it is a ceiling corner bay for reducing inter-floor noise that can secure workability by avoiding interference with installations such as ventilation ducts and hot and cold water pipes installed at the corners of the ceiling. It's all about the strap.

Social conflict due to inter-floor noise continues, and to resolve this, institutional measures to raise the floor slab thickness standard, high-performance floor impact sound buffering material development, and building structure development were in progress.

These measures can only be applied to new apartment houses, and cannot be applied to existing apartment houses.

In fact, civil complaints due to inter-floor noise are occurring in existing apartment houses built before the slab thickness standard was reinforced.

Therefore, there is a need to develop a technology that can reduce the noise between floors of existing apartment houses.

In addition, it is necessary to develop a technology that can be applied through several days of construction even in the state where a resident resides.

The development of floor impact sound ceiling materials has been proposed as a way to reduce inter-floor noise by installing through short-term construction in a residential state, and various ceiling materials are being developed.

Existingly developed ceiling material technologies include resonant sound-absorbing materials, porous sound-absorbing materials, and sound-insulating panels installed under the floor slab, and most of them are applied in the space between the slab and the gypsum board finish.

On the other hand, the problem of reducing the weight impact sound among the current inter-floor noise is large, and in order to reduce the weight impact sound, the development of a technology capable of controlling the noise of 100 Hz or less is required.

In addition, with regard to the post-floor noise post performance verification system that is being introduced through a public hearing recently, when a household whose weight impact sound does not meet the standard occurs, it is possible to reduce the low frequency band by supplementing the existing floor buffer and sound-absorbing material that can only reduce 125 Hz or more. There is a need to develop a technology that can supplement performance through ceiling reinforcement, which is easy to work compared to floor reinforcement, which takes a lot of time and cost.
