The light transmitting member 50 is a part forming a sound barrier and is formed of a transparent material. To this end, the light transmitting member 50 is preferably formed of glass (GLASS), PC (polycarbonate), or PMMA. Accordingly, visibility can be secured through the light transmitting member 50 .

In the above, it has been described that the socket bar 20 is inserted into the insertion portion 15 of the main frame 10 and then locked and fixed by the locking protrusion 14, but as shown in FIG. 7, the socket bar 20' ) In the form of being inserted into the insertion portion 15 of the main frame 10, the lower end may be bonded to the main frame 10 and integrally fixed.

In this case, it is natural that a space is formed between the socket bar 20' and the main frame 10 in a structure into which the slide slat 30 can be inserted.

Accordingly, the process of assembling the maintenance-type soundproofing panel of the present invention having the above-described configuration or separating and reassembling to replace the light transmitting panel will be described as follows.

When the soundproof panel is installed for the first time, the soundproof panel is first assembled.

That is, after inserting the socket bar 20 into the main frame 10, the shim block 25 is inserted into the shim block insertion groove 23 of the socket bar 20, and the main frame 10 and the socket bar 20 ) Insert the slide slat 30 to be movable up and down, respectively, in both gaps between. At this time, the position of the slide slat 30 should be secured so that the light transmitting member can be seated in the center of the socket bar 20. To this end, the slide slat 30 is pushed in the lower direction of the main frame 10 so that the bent portion 33 of the slide slat adheres to the upper surface of the main frame, and after the light transmitting member is inserted, the slide slat is again inserted into the upper part. By moving and fixing in the direction, the light transmitting member seated in the center of the inner socket bar 20 of the frame is fixed without being separated from the frame.

Subsequently, the main frame 10 in which the socket bar 20 and the slide slats 30 are coupled is brought into close contact with the inclined surfaces of the light transmitting member 50, respectively, so that the light transmitting member 50 is supported by the shim block 25, Assemble the four main frames 10 together.

When the assembly of the main frame 10 is completed, the assembly of the soundproof panel is completed by inserting the clamp bars 40 in which the gaskets are fastened from both sides of the light transmitting member 50 and fixing them to the main frame 10.
