The present invention relates to a sound absorbing panel including the assembly bracket.

In recent years, the diversification of transportation means and the traffic volume have increased due to rapid industrial development, and the roads, railroads, and airports in which these means of transportation are being expanded. As a result, residents living near roads, railroads, and airports are suffering greatly from noise generated by transportation. Therefore, when designing roads, railways and airports, noise standards of less than a certain level are strictly applied, and various types of sound barriers such as sound absorbing, reflective, interference, and resonance sound barriers are installed to satisfy such noise standards. Doing.

Here, a sound-absorbing soundproof wall made of aluminum, which is a typical example of a conventional soundproof wall, is constructed by installing an H-beam strut at a predetermined interval on a foundation stage, and installing sound-absorbing panels made of several layers of aluminum between each strut and strut. . At this time, the sound absorbing panel made of aluminum is formed with a plurality of holes at a predetermined interval on the outer surface, the inside has a configuration filled with a sound absorbing material such as asbestos.

However, the sound-absorbing sound barrier made of the existing aluminum material has a problem in that dirt or other foreign matters generated on the road in the aluminum panel is introduced into the inside through a plurality of holes formed on the outer surface thereof to contaminate the sound absorbing material as the inner filler. In addition, the sound absorbing materials are hardened by rain or snow, and after a long time, the function of the sound absorbing materials is lost, causing a problem in that the aluminum panels need to be replaced and installed.

On the other hand, in recent years, in order to solve the problems of the existing aluminum panel has been proposed a sound-absorbing panel using an inorganic material or lightweight foam concrete.

1 is a side cross-sectional view showing a representative example of a conventional inorganic sound absorbing panel.

Referring to FIG. 1, the inorganic sound absorbing panel 200 is extruded to provide a plurality of hollow parts 210 therein.

In the state is uniformly compressed using a roller 400 and the compaction rod 500 is subjected to a process of curing.

However, the conventional inorganic sound absorbing panel 200 is mixed with a predetermined size of particles and an adhesive as described above to form a sound absorbing layer 230, and then adhered by a compression method, the adhesive force of the adhesive after a long time after installation on the soundproof wall Along with this deterioration, there is a problem in that the sound absorption efficiency is drastically reduced due to desorption of particles due to external environment (strong wind, temperature change, etc.). In addition, the conventional inorganic sound absorbing panel 200 is a process of mixing the particles and the adhesive separately, the process of injecting the particles and the adhesive mixture to the spill prevention jaw 220 to form a sound absorbing layer, the roller 400 and the compaction rod ( There is a complicated problem in the manufacturing process since the compression / hardening process must be performed.

On the other hand, the sound-absorbing panel using lightweight foam concrete is constructed by installing a sound-absorbing plate made of lightweight concrete on the general concrete panel. Such a lightweight foam concrete sound-absorbing panel is heavy because the weight of the sound-absorbing panel itself is heavy.

Such lightweight concrete is made of porous materials using lightweight aggregates or foams, etc., and has the advantages of low self-weight, excellent sound absorption, and weak strength. In addition, as a kind of lightweight concrete that can be applied to the sound absorbing plate 4 of the present invention, general lightweight concrete using natural lightweight aggregate (volcanic gravel, coal ash) or artificial lightweight aggregate (plastic aggregate, perlite, vermiculite, briquette, poly-styrene) And foam concrete containing a myriad of bubbles in concrete, and lightweight foamed concrete, which is a preferred component, is prepared by adding water mixed with a foaming agent to cement mixed with pearlite and expanded vermiculite to produce mortar and vacuum pressurization of the mortar. Will be cured. Alternatively, the sound absorbing plate 4 is formed by mixing any one of blast furnace slug, volcanic stone and pulp, which is an inorganic material having pores as its constituent material, with cement. At this time, the blast furnace slug may be applied to the collected from the furnace. The scoria is a natural ceramic charcoal fired at a high temperature of 1600 degrees millions of years ago, and has the effect of promoting growth of all living organisms, destroying bacteria, and inhibiting proliferation. It is known that its content is more than 3%, and it is excellent in heavy metal adsorption rate and excellent in removing toxicity. The pulp is a natural material with little change in length due to temperature deviation and excellent in water resistance, fire resistance, and sound insulation. Therefore, when the sound absorbing plate 4 is formed by mixing any one of the blast furnace slug, volcanic stone, and pulp with cement, the silica sand, the mixture, and the water are further mixed, followed by curing.
