Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a noise suppression type prefabricated noise barrier,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a noise-suppressing type building soundproof wall, more specifically, to a hollow soundproof panel using transparent soundproof panels, which are stacked between H beam pillars provided at predetermined distances, When the aluminum frame is extrusion-molded, a part of the aluminum frame is opened in the longitudinal direction to form air and noise flow holes, and the air and the noise flow holes are allowed to pass air and noise to the sound absorption material filled in the aluminum frame By installing a louver, it is possible to reduce secondary and tertiary damage due to resonance that may occur when the noise generated from the roadway collides against the transparent plate of the transparent soundproof panel, and significantly increases the sound absorption effect on the noise. The air and noise distribution holes and the louvers are formed in a rectangular frame body (Left and right) frames of the upper, lower, left, and right frames of the transparent sound-proof panel having the image, and rainwater or the like flows into the inside of the frame of the transparent sound- The present invention relates to a noise-suppressing type building-constructed soundproofing wall which can be completely blocked while reinforcing the strength of a frame.

Modern society is experiencing a lot of noise due to various mechanical equipments and automobiles which are increasing, so that it is not comfortable office or residential life and is suffering from many stresses due to various noises.

Particularly, a structure of a soundproof wall for installing various soundproofing walls between an expressway, a railway, and the like, including an apartment complex or other residential areas and roads, It is very difficult to find a soundproof wall that is simple and soundproof.

Generally, a soundproof wall is installed around a road or a railroad on which a vehicle, a train, or the like travels, and the soundproof wall is installed to prevent noise generated from a vehicle or a train from being transmitted to a neighboring house or a building such as a school .

Herein, the above-mentioned noise generally refers to an undesired sound of an object to be listened, and includes not only sounds with high volume such as automobile noise, aircraft noise, train noise, etc., but also music with a high volume, .

As described above, the level of the sound according to the object to be listened is very subjective. The traffic noise generated by the road transportation means of the road is generally referred to as noise, and the traffic noise described above includes continuous background noise and individual vehicle noise .

Of course, the traffic noise generated from the highway or the main road where the traffic volume rushes is a mixture of many noise sources, and the noise of the individual vehicles is superimposed on the background noise of a large volume.

In order to prevent the above-mentioned traffic noise from reaching a residential area adjacent to the road, a soundproof wall is installed parallel to both sides of the road. The soundproof wall connects the plurality of wallboard members in a horizontal direction and a vertical direction So that the gap is formed by the connection portion so that the gap noise is not generated.

As described above, when the soundproof walls are disposed in parallel to the both sides of the road, the noise reflected by the soundproof walls is reflected in the opposite direction, thereby preventing noise from reaching the listener in the direction opposite to the installation of the soundproof wall.

In particular, in order to increase the absorption or reduction efficiency of the noise, the density and height of the wall member and the length and structure must be optimized, so that the density of the wall member must be sufficient to obtain sound attenuation effect and reduce the reflectivity of the wall member But also the respective wall member connecting portions must be sealed as described above.

Since the above-mentioned traffic noise is generated in a low frequency region of about 100 to 1,000 Hz, the wall member must be configured to maximize its absorption.

Conventionally, most of the soundproof walls include an H beam post that is installed or detachably installed at predetermined intervals in the foundation concrete formed along the road length direction on both sides of the roadway; And a sound insulation panel in which left and right ends of the outer frame are slidably engaged with corresponding vertical grooves between the H beam posts,

At the time of installation work of such a soundproof wall, first, the H beam pillars are fixed to the foundation concrete formed along the road length direction on both sides of the road with a predetermined interval and fixed so as to be buried or detachable, and between the H beam pillars, The left and right ends of the frame wrapped around the outer end are inserted, and then they are pushed down one by one from the upper end of the H beam support to be stacked and fixed.

A soundproof panel, which is installed between the H-beam struts, includes a pair of perforated holes through which noise can pass, a sound absorbing material disposed inside the perforated panel located on the front and rear surfaces, And a finishing plate for covering the outer peripheral surface (i.e., four surfaces) of the damping material including the perforated plate, or a transparent plate made of glass or the like, and a transparent plate fixing groove, And a frame shaped like a rectangular frame that is assembled in a form to surround the outer side.

The soundproof panel using the soundproof panel composed of the perforated panel, the sound absorbent panel and the finished panel is usually a sound absorbing soundproof wall. The soundproof panel having such a structure can not see various buildings inside the soundproof wall from the outside of the soundproof wall The soundproof wall made of a soundproof panel made of a transparent plate and a frame is called a transparent soundproof wall, which can be installed at a place where securing of a clear visual field is desired, and a soundproof wall in which the above two soundproof panels are appropriately combined is called a complex soundproof wall .

In the case of a transparent soundproof panel, which is composed of a transparent plate and a rectangular frame and is widely used in transparent sound insulation walls and composite sound insulation walls, the transparent sound insulation panel is formed in a fixing groove having a width wider than the thickness of the transparent plate The transparent plate is inserted and then caulked with silicone or the like to prevent the transparent plate from flowing.

However, since the transparent plate including the frame of the above-described transparent sound insulation panel has a completely flat shape, when the soundproof wall is installed using them, the noise generated in the roadway is not absorbed or destroyed through the transparent soundproof panels, The phenomenon that the noise including the transparent plate hits the frame and is reflected in all directions including the driveway is naturally incurred.

As described above, a part of the noise including the transparent plate of the transparent soundproof panel, which is reflected to the multi-direction including the roadway after colliding with the frame, is subjected to the noise having the same frequency as the natural frequency, And thus, there is a problem in that even though the soundproof wall is installed, the resonance leads to a larger noise damage.
