Detachable soundproof wall with load reduction function {DETACHABLE SOUNDPROOF WALL WITH LOAD REDUCTION FUNCTION}

The present invention relates to a detachable soundproof wall with a load reduction function, and is a detachable soundproof wall with a load reduction function that allows for easier disassembly and coupling between the soundproof panel, fixed frame, and fixed frame that constitute the soundproof wall.

Soundproof walls are walls installed to block sound, and are used in various forms in real life, such as being installed to prevent noise generated on the road from spreading to the surroundings, or installed to prevent mutual inconvenience in multi-generational housing.

Among these soundproof walls, in the case of soundproof walls installed to reduce traffic noise, the related regulations and construction methods are disclosed in the road construction standard specifications distributed by the Ministry of Land, Infrastructure and Transport, and current contractors refer to the related regulations and technologies to work in a more efficient direction. Improvements are being made to reduce traffic noise. Existing technologies are described with reference to currently published literature as follows.

First, in Korean Patent Publication No. 1614717 (“Sound-absorbing, transparent soundproof wall including load transfer prevention device”, announced on April 29, 2016), in the soundproof wall installed by stacking between H-beam steel supports to reduce road noise, , It is formed to obtain more structural stability through a transition prevention device installed between at least one pair of sound-absorbing panels.

Next, in Korean Patent Publication No. 1815516 (“Front soundproofing panel replacement device and soundproofing wall maintenance method using the same”, announced on January 5, 2018), in the soundproofing panel frame stacked up and down between H-beam steel supports, there are a plurality of soundproofing panels. The sound insulation plate frame is formed to be coupled to each H-beam support, providing simpler installation and maintenance for workers.

Lastly, in Korean Patent Publication No. 1445042 (“Replaceable Soundproofing Panel,” announced on September 26, 2014), in the replaceable soundproofing panel installed by stacking between H-beam steel supports to reduce road noise, it includes a movement prevention zone and A fixing clip is formed so that only the soundproofing panel can be separated and replaced without changing the structure.

As such, various methods have been disclosed in the disclosed technologies to make maintenance easier for soundproofing panels arranged between H-beam steel supports and in which a plurality of soundproofing panels are stacked up and down. However, although there are aspects of the existing problems that have been solved based on the relevant technologies, if the frame of the soundproof panel is attached directly to the H-beam, it may lead to the problem of the H-beam being more easily deformed due to the load being placed on it. In addition, when replacing the lower soundproofing panel, when the weight is transferred to the support, it must be constructed with a more sturdy structure, which may have the disadvantage of leading to an increase in facility costs. In addition, if it is formed with an unstable structure, the soundproofing panel on the upper side may fall downward due to its own weight, which may lead to problems such as the safety of workers replacing it or damage to the facility.
