Hereinafter, with reference to the accompanying drawings illustrating a preferred embodiment of the present invention will be described in detail.

Soundproof wall remodeling device 1 according to the present invention is a device having the same shape as one side of the bird wings soaring up into the sky, the coupling portion 10 is coupled to the soundproof wall (P) installed on the side of the road; An inclination part 20 having one end fixed to the coupling part 10 to an obtuse angle with respect to the soundproof wall, extending downward toward the road, and having a protrusion 21 formed therein; One end is connected to the other end of the inclined portion 20 and includes a vertical portion 30 extending vertically downward.

When the sound hits the sound barrier, if the wavelength of the sound is long (low frequency) in proportion to the size of the sound barrier, the sound is transmitted behind the sound barrier. However, if the frequency of the sound is high enough or less than or equal to the size of the sound barrier, the sound cannot go behind the sound barrier. So the sound you hear from afar or next door is the bass.

The very low frequency wavelength reaches 17 meters long and is close to wave-like wave motion. In contrast, the high frequencies are only a few centimeters short. Thus, it is close to ray motion. The treble can therefore be easily absorbed by porous materials such as sponges, reducing reflections. However, the bass with a large wavelength is diffracted to change the direction of movement when buried in the sound barrier. The bass is diffracted as it moves around the wall as water flows. The lower the frequency, the easier the diffraction. Therefore, bass becomes less easy to cut than treble.

When the remodeling apparatus 1 according to the present invention is attached to the soundproof wall, the spaces defined by the inclined portion 20 and the vertical portion 30 by the inclined portion 20 and the vertical portion 30 originating from the vehicle on the road and the inclined portion 20 are inclined. In the space divided by the projections 21 and 31 formed in the and vertical portions 30, reflection and diffraction occur in various directions and various sizes, and are trapped. It is effectively attenuated to prevent diffracted sound from flowing out behind the sound insulation board.

As shown in FIGS. 2, 3 and 4, it is preferable to form the projection 31 inside the vertical portion 30, and it is preferable to bend the other end of the vertical portion inward. In addition, it is more effective to prevent the diffraction sound when the protrusions 21 and 31 are manufactured in the form of ribs, and the free ends of the protrusions are bent in both directions (for example, arrowheads) as shown in the above embodiment, or are not shown. When bending in one direction, the diffraction sound is more effectively trapped as reflections and diffraction occur in various directions and in various sizes to prevent various forms of overlap and prevent the diffraction sound from flowing behind the sound insulation board.

In addition, although not shown, even if the lengths of the protrusions 21 and 31 are differential, reflection and diffraction occur in various directions and various sizes, they are confined, and various types of overlapping are prevented, and diffraction sounds are prevented from flowing out behind the soundproof wall.

The remodeling apparatus 1 according to the present invention may be manufactured by extruding a metal such as aluminum, by extruding or injecting a rigid plastic, or by processing wood by compression or the like.

In addition, the remodeling apparatus 1 may be integral with the coupling portion 10 and the inclined portion 20 as in the above implementation, and may be detachable, although not shown.

In the illustrated example, the reflector mounting groove 22 and the sound absorbing material mounting groove 23 are formed outside the inclined portion, and the reflector 22-1 and the sound absorbing material 23-1 can be coupled thereto. Reflectors such as light reflection tapes and luminous tapes function to induce safe driving by checking the position of road noise barriers. The sound absorbing material functions to supplement or satisfy the insufficient sound absorption performance of the existing soundproof walls. Of course, the device may couple the sound absorbing material to the inclined portion 20, the vertical portion 30, or both of the lower surface or the upper surface thereof, or the reflective portion may be coupled to the outer side of the inclined portion 20, the vertical portion 30 or both. have.

In addition, the apparatus 1 imparts a predetermined pattern with discoloring, luminous or fluorescent pigments, inks or paints in its manufacture, or imparts a predetermined pattern with a sticker or silkscreen print having a discoloring, luminous or fluorescent function. It can be transformed into a road sound wall that fits the landscape and aesthetics of modern roads with the ability to display beautiful and diverse colors on soundproof walls, discoloration, luminous and fluorescent lights.

For example, in the manufacturing process of the device, by using a pigment, ink or paint with discoloration, luminous or fluorescent on the outer surface, various colors, shapes and pictures may be displayed so that the colors and shapes change depending on the ambient temperature. In this way, the road landscape is beautiful at night and it can be helpful for safe driving by securing visibility of night driver.

For reference, beautiful colors and flowers in spring, cool beaches in summer, beautiful autumn leaves and fields in autumn, quiet villages and mountains in snowy winters, and so on.

In addition, the device 1 may be combined with a solar module and lighting means. The solar module is preferably attached to the front of the device 1, preferably to the front of the inclined portion 20, such as power storage means, at least a control means having a switch for turning on / off the electricity supply by an optical sensor. The photovoltaic facility may be disposed on the top surface of the device 1 or on an existing soundproof wall. As such, when the solar module and the lighting means are combined with the present device, it is preferable to produce a night light and a beautiful night view.

Hereinafter, a method of remodeling a soundproof wall installed using the apparatus will be described by the method of the embodiment.
