Here, of course, the transparent plate 10 may be replaced with an opaque plate, a wood material, or a sound-absorbing panel having a built-in sound-absorbing material.

The edge frame 20 is formed in a structure to support the edge portions of the transparent plate 10 in four directions, up, down, left, and right.

That is, the edge frame 20 has a predetermined length to stably surround and support the upper, lower, left, and right edges of the transparent plate 10 and its cross-section is as if a pipe-shaped member having an empty cavity (hollow) inside has a rectangular frame shape. It is formed by a combined structure.

And on the front surface of at least one of the upper and lower portions of the edge frame 20, a plurality of sound-absorbing holes 21 are arranged at regular intervals to absorb and cancel the sound.

In addition, a sound absorbing material 22 for absorbing and extinguishing the sound flowing into the hollow inside through the sound absorbing hole 21 is built in the edge frame 20 .

And a fixing jaw 23 on which the edge of the transparent plate 10 is seated is formed inside the front surface of the edge frame 20 , and the edge of the transparent plate 10 is attached to the fixing jaw 23 on the fixing jaw 23 . ) The bracket 24 for fixing to the screw 25 is fixed at regular intervals by tightening.

That is, the bracket 24 protects the four edges of the transparent plate 10 and the shape of the cross section is the front edge of the transparent plate 10 and the fixed jaw of the edge frame 20 in order to implement a simple image in design. (23) It is formed in an L-shape that is closely attached to the edge.

Here, the edge frame 20 is made of aluminum alloy, galvanized steel, etc. to prevent structural deformation by ensuring bending rigidity and strength, and to have a thickness that ensures resistance to horizontal wind loads and minimizes deflection in the load direction. It may be extruded and molded into a predetermined cross-sectional shape, such as a fine channel bar.

The rotating curved protrusion 30 is integrally located at the top of the edge frame 20 along the longitudinal direction so that it can be bent and unfolded within a certain angular range along one axis through a hinge joint combination with another soundproof plate installed adjacently. is formed

That is, the rotating curved protrusion 30 is formed in a bar shape having a semicircular or bulb-type cross section at the upper end of the edge frame 20 .

And a first stopper ( 31) is formed.

The rotating curved groove part 40 is the edge frame 20 so that it can be bent and unfolded within a certain angle range along one axis through a hinge joint coupling with the rotating curved protrusion 30 of another soundproof plate installed adjacently. It is formed in a shape corresponding to the rotating curved protrusion 30 of the other soundproofing plate.

That is, the rotating curved groove portion 40 is formed in a groove shape having a semicircular or bulb-type cross section at the lower end of the edge frame 20 .

In addition, at least one gasket groove 41 for inserting the gasket 50 is formed in the rotating curved groove portion 40 .

That is, when the first and second stoppers 31 and 42 are rotated and unfolded by the rotation curved groove part 40 of another soundproof plate adjacent along the axis of the rotation curved surface protrusion 30, their respective edge frames 20 are vertical. It serves to cause mutual contact interference with the rear edge of the rotating curved protrusion 30 and the rear edge of the rotating curved groove portion 40 of the other soundproofing plate to achieve a standing state.

At least one gasket 50 is fitted in a gap between the rotating curved protrusion 30 and the rotating curved groove portion 40 of another soundproof plate adjacent to each other to maintain waterproofness and airtightness.

That is, the gasket 50 airtightly blocks the gap between the rotating curved protrusion 30 and the rotating curved groove portion 40 of another soundproof plate adjacent to the elastic deformation and restoring force, thereby blocking the leakage of rainwater as well as the road. It prevents noise from leaking out to the rear.

Here, the gasket 50 is made of an elastic material such as rubber or silicone in the form of a band having a certain length, and is inserted into the gasket groove 41 of the rotating curved groove part 40 in a sliding manner to maintain a state not to be separated. It can be joined by a dovetail joint.

For example, the gasket 50 may maintain a state not to be separated while being fitted with a part of the gasket groove 41 in a slide manner, and the remaining part may be elastically deformed by elasticity when in close contact with the rotating curved protrusion 30 . The shape of the cross-section may be formed in the shape of a tube having a hollow so as to maintain the airtightly adhered state.
