Description

Technical Field

[0001] The utility model relates to a noise protection device, in particular to an anti-falling sound barrier. Background Art

[0002] Sound barriers are mainly used for sound insulation and noise reduction on roads, highways, elevated composite roads and other noise sources. They are divided into pure sound insulation reflective sound barriers and composite sound barriers that combine sound absorption and sound insulation. The latter is a more effective sound insulation method. It refers to a wall-like structure set up on the side of railways and highways to reduce the impact of driving noise on nearby residents. Soundproof walls are also called sound barriers. Inserting a facility between the sound source and the receiver so that the propagation of sound waves has a significant additional attenuation, thereby reducing the noise impact in a certain area where the receiver is located, such a facility is called a sound barrier. It is divided into traffic sound insulation barriers, equipment noise attenuation sound insulation barriers, industrial plant boundary sound insulation barriers, and roads and highways are the places where various types of sound barriers are used the most.

[0003] Existing sound barriers are generally composed of columns and sound barrier unit plates inserted between the columns. The columns are generally H-shaped steel columns, and the sound barrier unit plates are inserted between adjacent steel columns. The characteristic of this structure is that the two ends of the sound barrier unit plates are fixed in the same way. If a collision occurs, the sound barrier unit plates will be deformed by the impact and can easily fall off from between the columns, causing secondary disasters. Therefore, how to design a sound barrier that will not fall even after being deformed by an impact is a technical problem that needs to be solved. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an anti-falling sound barrier.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A fall-prevention sound barrier comprises a plurality of columns arranged in sequence and a sound barrier unit plate inserted between adjacent columns, wherein the sound barrier unit plate comprises an outer shell and a sound-absorbing component located in the outer shell, wherein the outer shell comprises a front panel, a back panel, an upper side panel, and a lower side panel, wherein the columns comprise a bottom plate and a plate column and a cylinder fixed on the bottom plate, wherein a cylindrical structure is arranged at one end of the outer shell, and a semi-cylindrical structure is arranged at the other end of the outer shell, wherein the cylindrical structure is sleeved on the cylinder, and the semi-cylindrical structure is clamped on the cylinder.

[0007] The cylindrical structure is an aluminum profile cylinder, which is fixed to one end of the shell, and the semi-cylindrical structure is an aluminum profile semi-cylinder, which is fixed to the other end of the shell.

[0008] The cylindrical structure is formed by bending the end of the shell, and the semi-cylindrical structure is formed by bending the other end of the shell.

[0009] The plate column is located on the sound-facing side of the sound barrier, and the circular column is located on the back-to-sound side of the sound barrier.

[0010] The beneficial effects of the utility model are as follows: the anti-fall sound barrier provided by the utility model has the sound barrier unit plate deformed after being hit, one end of which is separated from the column, and the other end, due to the sleeve structure, will only rotate instead of falling on the road surface, thereby preventing pedestrians and vehicles from suffering secondary injuries. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 This is a schematic diagram of the overall structure of the sound barrier unit panel. DETAILED DESCRIPTION

[0013] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0014] like Figure 1 , 2 As shown, an embodiment of the utility model provides an anti-fall sound barrier, which includes a plurality of columns arranged in sequence and sound barrier unit plates inserted between adjacent columns. The columns are arranged in rows at certain intervals and fixed on both sides of the road. The columns include a base plate 21 and plate columns 22 and cylinders 23 fixed on the base plate. The plate column 22 is a rectangular plate-like structure, and the cylinder 23 is a long cylindrical body. When installed, the plate column 22 is located on the sound-facing side of the road, and the cylinder 23 is located on the back-sounding side of the road. The plate column 22 and the cylinder 23 can be made of metal materials or cast from cement concrete. The sound barrier unit plate includes a shell and a sound absorbing component located in the shell. The shell includes a panel 11, a back plate 12, an upper side plate 13, and a lower side plate 14. A cylindrical structure 31 is provided at one of the left and right ends of the shell, and a semi-cylindrical structure 32 is provided at the other end. One end of the sound barrier unit plate is fixed on the cylinder 23 through the cylindrical structure 31, and the other end of the sound barrier unit plate is clamped on the cylinder 23 through the semi-cylindrical structure 32. Specifically, the cylindrical structure 31 is a cylinder made of aluminum profile, which is fixed to one end of the shell through an end plate at one end of the shell. The semi-cylindrical structure 32 is a semi-cylinder made of aluminum profile, which is also fixed through an end plate at one end of the shell. As other structural options, the above-mentioned cylindrical structure is formed by bending the end plate of the shell, and the semi-cylindrical structure is formed by bending the end plate at the other end of the shell.

[0015] When the sound barrier of the above structure encounters a collision, the instantaneous impact force will cause the sound barrier unit plate to bend and deform. One end of the sound barrier unit plate will detach from the cylinder, effectively alleviating the impact force, while the other end will not fall to the road surface because it is fixed on the cylinder, avoiding secondary damage.

[0016] The embodiment described above is only one of the more preferred specific implementation methods of the utility model. Common changes and substitutions made by technicians in this field within the scope of the technical solution of the utility model should be included in the protection scope of the utility model.
