Description

Soundproof wall structure {Structure of Soundproof BOARD}

The present invention relates to a high-efficiency soundproof wall structure for noise blocking in places where noise is generated such as highways, general roads, subways, railways, factories, schools, hospitals and airports.

In general, the soundproof wall installed in a noisy place has not been punched in the upper and lower fittings and holes of a flat face plate with a plurality of sound absorbing holes as disclosed in Korean Utility Model Publication (Publication No. 95-25154). It is coupled through the fitting groove of the rear plate, and the sound absorbing body in the interior to block the noise. The soundproof wall of such a structure may form a single soundproof wall by combining the fitting protrusions and the fitting grooves formed on each of the front panel and the rear panel, but the upper projections of the front panel and the rear panel and the upper projections of the front panel and the rear panel. Each of them protrudes upwards and downwards so that they cannot be fitted to each other, so it is difficult to combine and stack the soundproof plate and the soundproof plate in the vertical direction, and when the soundproof plate is installed between the H beams, the front and rear panels are sandwiched between the H beams The front panel and the H-beam are made of metal, so they are not suitable for blocking noise by generating noise while flowing in wind pressure or external impact.The front panel is made of almost flat plates, so the noise cannot be attenuated by collision. The problem that can not block the noise is pointed out.

The object of the present invention is to block noise effectively and efficiently improve the function of the soundproof wall, and provide the convenience of construction by providing the simplicity of assembly.

The present invention assembles the soundproof wall and the soundproof wall that assembled the front and rear soundproof panels up and down continuously, and further attenuates the attenuated noises in the second and third order by bumps and bumps formed on the front plate of the soundproof wall to increase the noise blocking efficiency. Make it a technical task.

The present invention for achieving the above object is to form a plurality of sound-absorbing holes in the bent portion of the square wave formed in the longitudinal direction of the front plate constituting the soundproof wall, and to form a recess in the center of the back plate, A space portion is formed in the lower portion, the primary sound absorbing body is inserted into each of the bent portions of the front plate, and the secondary sound absorbing body is installed in the space inside the front and rear plates, and the fitting protrusion below the soundproof wall and the upper side of the soundproof wall. The soundproof wall and the soundproof wall are assembled up and down continuously by fitting the fitting grooves, and a soundproof wall is installed between the H beam and the H beam, and a buffer rubber is interposed between the outside of the bent portion of the front plate and the H beam, and both sides of the soundproof wall and H It is characterized by comprising a finishing cap sandwiched between the inner surface of the beam.

The present invention is formed by projecting downward on the upper and lower sides of each of the front and rear panels 11 and 12 expressing the composite coating (for strengthening the surface hardness of the front and rear plates), powder coating, transfer, and pattern. In the soundproof wall 10 which forms the fitting grooves 11 'and 12' to couple the front and rear plates 11 and 12, and inserts the grooves 13 therein, the front plate 11 A plurality of sound absorbing holes 11A are formed in the square-shaped bent portion 11 'formed in the longitudinal direction of the inside, and the recessed portion 12' is formed in the center of the rear plate 12 to form the inside of the rear plate 12. Space portion 12A is formed on the upper and lower portions, and the primary sound absorbing body 13A is inserted into each of the bent portions 11 'of the front plate 11, and the front and rear plates 11, 12 are inside. The secondary sound absorbing body 13B is installed in the space of the soundproof wall, and the fitting protrusion 10A below the soundproof wall 10 and the fitting recess 10B above the soundproof wall 10 are fitted to the soundproof wall 10 and the soundproof wall ( 10) up and down continuously assembled H beam 20 and H beam 20 After installing the soundproof wall 10, the buffer rubber 30 is interposed between each of the bent portions 11 'of the front plate 11 and the H beam 20, and both sides of the soundproof wall 10 and the H beam ( 20) to insert the finishing cap 40 between the inner surface. In the fitting projection 10A is formed in the lower portion of each of the front and rear plates, and shows the entire fitting groove 11 ', 12' showing a downwardly protruding shape, the fitting groove 10B is the front, The fitting grooves 11 'and 12' which are formed on the upper side of each of the rear plates and are shown to protrude downwardly are shown. The fitting recesses 11 ′ and 12 ′ may have a semicircular shape (see FIG. 4) or a reflective leg shape (see FIG. 9), and as shown in FIG. 10, a fitting groove portion having a semicircular shape or a reflective leg shape ( 11 ') (12') without forming the engaging jaw (11-1) (12-1) can be combined with the front and rear plates (11, 12), to facilitate the discharge of rain water, Backplane (11, 12) each image. The lower surface can be formed to be inclined. In addition, the cover 50 is fixed to the space portions on both sides of the upper side of the soundproof wall 10, and the cover 50 may cover and fix the entire upper end of the soundproof wall 10 (see FIG. 7). Then, as shown in FIG. 8, grooves 10C may be formed at both ends of the soundproof wall 10 to be fitted to the H beam 2, and the grooves 10C at this time may include a front plate constituting the soundproof wall 10 ( It is preferable to form in 11). 60 in the figure is a fixing member.

The present invention of such a configuration is that the soundproof wall 10 is coupled by the fitting grooves 11 'and 12' of the front and rear plates 11 and 12, the fitting protrusion 10A and the fitting groove 10B. ), The upper and lower soundproof walls are easily coupled in the vertical direction, and the cushioning rubber 30 is installed between the front plate 11 and the H beam 20 to absorb shocks due to wind pressure or external impact. The noise generated from the soundproof wall 10 itself is prevented, and as shown in FIG. 5, the noise collided with the front plate 11 is repulsed or absorbed and attenuated by the primary sound absorbing body 13A through the sound absorbing hole 11A. . That is, the front plate 11 forms the bent portion 11 'and the noise is collided and attenuated by the bent portion 11' and further attenuated by the primary sound absorbing body 13A. The noise sucked into 13A) is attenuated secondarily by the secondary sound absorbing body 13B, and then remains or disappears partially in the state remaining in the upper and lower spaces 12A in the rear panel 12, so that the noise blocking efficiency is greatly increased. Is improved.

Meanwhile, the present invention maintains the fixing of the soundproof wall 10 through the fixing member 60, but as shown in FIG. 8, the groove 10C is fitted to one end of the H beam 20 on both sides of the soundproof wall 10. Fixing and maintaining the soundproof wall 10 can be carried out more firmly.

The present invention allows the soundproof wall and the soundproof wall to be coupled to each other through the fitting protrusions and the fitting grooves of the semi-circular shape or the reflective leg, and thus, the height of the soundproof wall can be greatly increased and firmly coupled, and the bent portion of the front plate can be combined. And absorbing and dispersing the noise through the primary and secondary sound absorbers to have the effect of blocking the noise, and also to absorb the shock from the external shock or wind pressure delivered to the soundproof wall to block the noise generated from the soundproof wall itself. It has the effect of providing high-efficiency noise-blocking function, and makes the soundproof wall beautifully visible through composite coating, powder coating, transfer, etc., and is suitable for soundproof walls such as roadsides, highways, and high-speed trains.
