Description

Removable Sound Absorbing Panel {ATTACHABLE-REMOVEABLE SOUND ABSORPTION PANEL}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary soundproof wall, and more particularly, to a removable sound absorbing panel that enables a sound absorbing panel to be detachably attached to horizontal steel pipes such as temporary soundproof walls, temporary fences, scaffolds, and the like in building construction.

In general, materials used for construction are piled up in various places and construction sites such as new buildings, renovations, roadsides, etc., which damages the aesthetics of the surrounding environment and generates noises such as dust and various mechanical sounds generated by the construction. These dusts and noises cause serious environmental and noise pollution in houses, offices, and schools located near the construction site. Dust and noise not only harm the pedestrians or the occupants of buildings, but also cause tremendous stress. Will be.

Therefore, in order to solve the above problems, fence-shaped temporary soundproof walls are installed along the periphery of the construction site in order to block the aesthetics that damage the surrounding environment generated during construction and the emission of dust and noise to the outside. Most soundproof walls are equipped with sound absorbers.

An example of such a temporary soundproofing wall is the Republic of Korea Utility Model Registration No. 275007 (hereinafter referred to as "prior art"), such a prior art is inclined steel pipe fixed to the base steel pipe (A) as shown in FIG.
