[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] like Figures 1 to 13 As shown, this embodiment provides a modular replaceable two-way sound-absorbing barrier, including a column and a screen body 14. The bottom of the column is used to connect to the foundation. Receiving grooves are provided on both sides of the column, and the ends of the screen body 14 are inserted into the receiving grooves.

[0036] In this specific embodiment, the column can be made of H-shaped steel 1, and the two sides of the H-shaped steel 1 are used as receiving grooves to limit the screen body 14. The bottom welding base of the H-shaped steel 1 is fixed on the foundation by bolts.

[0037] The end of the screen body 14 is provided with a head assembly 9, and a plurality of elastic parts are provided on the side of the head assembly 9 facing the column. The elastic part adopts a rigid damping spring. The self-balancing spring 11 keeps the screen body 14 in the center position at all times, and can also detect whether the spring action at either end fails by aligning the upper and lower diameters of the front holes. The head assembly 9 is provided with an anti-falling hole 10. The anti-falling effect is achieved by connecting the anti-falling hole 10 and the anchor bolts through a steel wire rope.

[0038] The plate-column elastic component 12 is arranged between the two sides of the screen body 14 and the receiving groove, one end of the plate-column elastic component 12 is connected to the screen body 14, the other end of the plate-column elastic component 12 is connected to one end of the barbed tooth plate 13, and the other end of the barbed tooth plate 13 is in contact with the column. The plate-column elastic component 12 and the barbed tooth plate 13 can keep the screen body 14 and the H-shaped steel 1 relatively fixed without contact, avoiding direct contact between the screen body 14 and the H-shaped steel 1, which is easy to produce collision and noise.

[0039] The top of the screen body 14 at the top is provided with a top cover plate 2. A U-shaped rubber strip is provided between the top cover and the screen body 14, and the top cover plate 2 can protect the top of the screen body 14 and prevent rain and dust from entering the screen body 14.

[0040] A top plate is arranged on the top of the column. Bolt holes are arranged on the top of the H-shaped steel 1, and the top plate covers the top of the H-shaped steel 1 and is fixed by bolts.

[0041] The screen body 14 includes a sound barrier perforated plate 3, a sound absorbing component 4, a fixed slot 5, a curved foam aluminum material 6 and a support member 7; the support member 7 is an I-shaped structure, a first limiting portion is provided at one end of the support member 7, a sound barrier perforated plate 3 is provided on both sides of the support member 7, both ends of the sound barrier perforated plate 3 are bent inward, both ends of the sound barrier perforated plate 3 are connected to the first limiting portion, and fixed slots 5 are provided on the outer sides of both ends of the sound barrier perforated plate 3; a sound absorbing component 4 is provided on the inner side of the sound barrier perforated plate 3, a reverberation chamber 8 is formed on the inner side of the sound absorbing component 4, and the reverberation chamber 8 is provided with a curved foam aluminum material 6.

[0042] The sound absorbing component 4 includes a sound absorbing material, a wrapping material and a support body. The sound absorbing material is arranged inside the wrapping material, and the support body is arranged outside the wrapping material. The sound absorbing material is made of rock wool, the wrapping material is made of alkali-free hydrophobic glass fiber cloth, and the support body is made of aluminum plate mesh or steel plate mesh. The sound absorbing component 4 as a whole has high-strength support performance and will not collapse after long-term use. Even if it collapses, the external wrapping material will integrate the rock wool together to achieve the effect of sound absorption and noise reduction; the surface openings of the aluminum plate mesh or steel plate mesh are φ2 small round holes. Even if raindrops enter, the size of the freely falling raindrops is larger than the size of the support mesh and will not enter the side of the sound absorbing material, thereby protecting the sound absorbing material and achieving the effect of double protection.

[0043] The sound barrier perforated plates 3 on both sides of the screen body 14 are made of the same structure and the same material, so that the two sides can be interchanged, which can meet the owner's demand for surface color matching. After one side of the screen body 14 is damaged by impact, the other side of the screen body 14 can be directly used for quick replacement. The high opening rate is used to improve the overall sound absorption performance of the sound barrier. The sound barrier perforated plates 3 are provided with multiple bends and can withstand higher wind pressure loads to be suitable for typhoon areas. The two ends of the screen body 14 rely on support members 7 to fix and support the sound barrier perforated plates 3 on both sides, so that rainwater on the top cover plate 2 can flow to the outside of the sound barrier perforated plates 3, thereby protecting the internal sound absorption material.

[0044] In a more specific embodiment, the first limiting portion is a hook-shaped structure provided on both sides of one end of the support member 7 away from the column. The fixing slot 5 is a C-shaped sheet metal. The sound barrier perforated plate 3 is a C-shaped sheet metal, and both ends of the sound barrier perforated plate 3 are bent inward, and the ends of both ends of the sound barrier perforated plate 3 are bent into a second limiting portion, and the second limiting portion matches the first limiting portion, and a plurality of through holes are provided on the sound barrier perforated plate 3.
