Description

ONE BODY TYPE PLASTIC SOUNDPROOFED WALL}

The present invention relates to an integrated plastic clean soundproof wall, and more particularly, simple and easy installation of the soundproof wall for noise attenuation, as well as to prevent each connection part (coupling part with the frame (H beam)) from being exposed to the outside. By expressing a beautiful appearance, each soundproof wall assembled in a multi-layer has a closed soundproof room form, so it can completely attenuate even low-frequency fine noise, foreign matters (dust) introduced into the soundproof wall The present invention relates to an integrated plastic clean soundproof wall that can reduce the cost by discharging the product, that is, molding the soundproof wall into an integrated single injection.

In general, the soundproof walls are for absorbing and dissipating and dissipating noise, and are mainly installed in places where schools, hospitals, residential areas, etc., which are adjacent to the road need to prevent noise.

Currently, loud noise, a by-product of industrial development, is an unavoidable reality due to the increase in the number of vehicles and the increase in the number of machinery. A soundproof wall was developed to meet this purpose.

On the other hand, the conventional soundproof wall is shown in each of the soundproof walls (3) in the support frame (1) consisting of the 'H' beam upright installed by a fixing means (anchor bolt, not shown in the figure), as shown in the accompanying drawings Figure 1a, b 10) After the end is positioned, a separate fixing body 2 is inserted and fixed between the support frame 1 and the soundproof wall 10, or as shown in FIG. 1B, the soundproof wall 10 thickness (built-in sound absorbing material) To increase the thickness of the)) is coupled to the slide so as to slide to the support frame 1, the shielding piece 12 integrally formed at the end of the soundproof wall 10 is installed so as not to be exposed to the outside wrapped around the support frame (1).

However, in the conventional soundproof wall as described above, in the case of the former (refer to FIG. 1A), a separate fixture is required to install the soundproof wall. Not only the appearance is not beautiful because it is exposed, but also the soundproof wall thickness is thin, it has the soundproof, that is, the closed end of the noise reduction rate is reduced, and in the case of the soundproof wall according to the latter (see Fig. 1b) integrally formed on the soundproof wall Although the support frame exposed to the outside is shielded by the shielding piece, the beauty of the appearance is relatively improved, but another aesthetic problem occurs due to the protruding shielding piece to shield the support frame.

In addition, the conventional sound-proof walls are mostly using the aluminum outer wall, but the aluminum is not enough strength of the outer wall is damaged even a little external force, when oxidized and corroded after installation is unclean and fade quickly to become a road environment deterrent element, the aluminum material The soundproof walls of the building are loosened as the assembly parts generated by the vibration of the car or train after construction not only decreases the soundproofing performance due to the generation of gap noise between the parts, but also absorbs the sound absorbing materials such as glass fibers inside. It is very bad in terms of environmental aspects such as wet or scattered, and recently it has been identified as a carcinogen in connection with the human body.
