Description

Sound-absorbing sound insulation board {SOUND ABSORBING TYPE SOUNDPROOFING PANEL}

The present invention relates to a sound-absorbing sound insulation board for blocking or removing various noises generated from a vehicle, a railroad, a factory, and more specifically, a curved portion protruding in a round shape and a concave portion recessed into a concave portion going from the top to the bottom. As a result, a plurality of front plates formed in succession are combined to surround the outer surface of the H beam on both sides, so that the H beam is not visible from the outside, so that the aesthetic view is good and the sound absorbing material is filled in close contact with the inside of the front plate to increase the sound absorption surface area, that is, the sound absorbing force. When the noise is diffracted by the increase of the path is in contact with the surface of the sound absorbing material is extended to improve the sound-absorbing sound effect of the sound absorption type.

In general, sound-absorbing sound insulation boards are installed at the edges of roads to reduce noise and create a pleasant road environment in noisy places such as railways, airfields, and various roads. The sound-absorbing soundproof plate has a structure in which a sound absorbing material made of glass wool or polyester is inserted therein and the front plate and the back plate as a whole, and the side plate is coupled to the side. Such sound-absorbing sound insulation boards use two kinds of flat surfaces, or have two kinds of uneven portions protruding from each other so that a portion of the front panel is angled, and among them, the latter case is used a lot. Referring to an example of the sound-absorbing soundproof plate used in recent years, the sound-absorbing soundproof plate of Utility Model Registration No. 197413 consists of a front plate 10, a back plate 20, and a side plate 30, and the sound absorbing material 40 inside the front plate 10. ) Is to be installed, to form the irregularities on the front plate 10 on the side where the noise is generated, but the portion of the irregularities that went out of the recess portion 14 between the convex portion 16, the recess portion 14 and the convex portion 16 An inclined slope 18 is formed and a sound absorbing hole 12 is totally drilled in the convex portion 16, and the recessed portion 14 and the lower inclined surface 18b are perforated in a slot shape of a long elongated hole and the convex portion 16. It is configured to be punched in a gallery type.

In the sound absorbing soundproof plate, the corners of the front plate 10 are angled, and in the case of the sound absorbing hole 12 formed in the protruding convex portion 10 and the convex portion 10, the noise moving at various angles is the convex portion 16 and the sound absorbing hole. In the case of reflected sound waves, some of the reflected sound waves pass through the sound absorbing holes 12 and are absorbed and absorbed by the sound absorbing material 40, but in the case of sound waves that are not, the corners of the convex portions 16 are angled. Sound waves hitting the side of the sound absorbing hole 12 has a disadvantage in that the reflection effect and the diffraction effect while the sound energy accumulates in the corner portion to increase the diffraction energy to reduce the sound attenuation effect of the noise by the soundproof plate.

The member 50 is comprised.

The sound absorbing sound absorbing plate 1 tends to accumulate at the edges having a sharp shape when noise is diffracted in the direction of the sound absorbing point. The front panel is provided to prevent the sound energy from accumulating on the front plate 10. 10 is formed symmetrically with each other in the same structure on the front and back as shown in Figure 1 and 3. As the lower portion from the front to the lower portion of the curved surface 11 protruding in a round shape and the concave portion 12 concave inwardly formed in a streamline form a plurality of continuous and a plurality of sound absorbing holes at regular intervals ( 13) is formed in total, and when the noise generated from the outside collides with the front plate 10, the sound waves are primarily absorbed by the sound absorbing material 20, which will be described later, through the sound absorbing hole 13 of the front plate 10. Sound waves impinged on the curved portion 11 and the concave portion 12 of the front plate 10 perform a reflection action and a diffraction action to form a rounded surface of the curved portion 11 and the concave portion 12 having a streamlined shape. While riding, the sound is absorbed by the sound absorbing hole 13 to reduce noise. Since the plurality of sound absorbing holes 13 formed in the curved portion 11 and the concave portion 12 are formed in a specific direction, the noise generated from various angles can be attenuated.

A fastening hole 14 is formed in each of the recesses 12 of the front plate 10, and is fastened and fixed to the side wall 42 of the side plate 40, which will be described later. An upper plate 15 and a lower plate 16 each having one end bent upward in the same structure are formed on the upper and lower portions of the front plate 10, and the upper plate 15 is bent to a certain height to the upper part of the insertion protrusion 17. ) Is formed and an insertion hole 18 is formed in the lower plate 16 on the other side, so that the insertion protrusion 17 is stable to the insertion hole 18 when a plurality of sound-absorbing soundproof plates 1 are coupled to the H beam 2 in the longitudinal direction. It is formed so that it can be stacked. At this time, the bent portion 31 of the inner frame 30, which will be described later, is located between the insertion protrusion 17 and the insertion hole 18, and bolts are formed in the fastening hole 14 formed in the upper plate 15 and the lower plate 16. (B) is fastened by fixing.

In addition, the upper plate 15 and the lower plate 16 of the front plate 10 are formed to be shorter than both end portions of both sides of the front plate 10 so as to surround the exterior of the H beam 2 when both ends are combined with the H beam 2. An insertion groove 19 is formed between the front plate 10 and the inner frame 30.
