Field of the Invention The present invention relates to a rear replaceable soundproof panel assembly, and more particularly, to a panel panel which can replace a senile or damaged panel with a new panel in a simple and quick manner from the rear due to a long installation, The present invention relates to a rear replaceable soundproof panel assembly that can be installed in a soundproof wall structure so as to be detachable in various combinations.

Generally, it is essential to install a sound barrier using a sound-absorbing panel having a certain length and a certain height in the noise transmission path of the road side in order to reduce the noise generated while driving a vehicle around a dense housing or a school.

Soundproofing walls installed for the purpose of blocking the noise of the roadside are divided into a sound absorbing type sound absorbing wall for absorbing and reducing noise and a reflection type for reflecting and blocking noise. In the case of a sound absorbing type for absorbing noise, a sound absorbing material is inserted into a soundproof panel, And absorbs the noise introduced therefrom as a sound absorbing material to sound the sound.

In addition, a sound-absorbing panel may be installed so that the dust and noise generated when the old building is demolished can not be transmitted to the outside of the construction site even when the old building is to be demolished.

Such a sound-absorbing panel realizes a sound barrier having a desired height and width by arranging pillars constituted by beams in an H-section on a regular interval and sequentially fitting them in a height direction between adjacent pillars.

In addition, the sound-insulating wall adopting such a sound-absorbing panel secures visibility, thereby achieving harmony with the surrounding environment, securing a wide field of view to help safe driving, and enabling mining on the road, And a transparent panel capable of rapidly dissolving snow-covered snow can be obtained.
