Description

Technical Field

[0001] The utility model relates to a noise protection device, in particular to a novel 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 a new type of anti-falling sound barrier.

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

[0006] A new type of anti-fall sound barrier, which includes several columns arranged in sequence and sound barrier unit plates inserted between adjacent columns, the sound barrier unit plates include an outer shell and a sound absorbing component located in the outer shell, the sound absorbing component includes a sound absorbing layer and a sound insulation layer, the outer shell includes a panel, a back plate, an upper side plate, and a lower side plate, and also includes a cross bar, which is arranged on the lower side of the upper side plate and is fixed to the sound absorbing component through a hoop.

[0007] Preferably, the crossbar is a cement concrete cylinder.

[0008] Preferably, the cross bar is a hollow metal cylinder.

[0009] Preferably, the shell is a structure formed in one piece by bending a metal plate.

[0010] The beneficial effects of the present invention are as follows: the new anti-fall sound barrier provided by the present invention, after being hit, the sound barrier unit plate is deformed and separated from the column, while the cross bar, due to its greater strength, will still remain between the columns to form a fence structure, and the sound barrier unit plate will still be hung on the cross bar and rotate around it without falling off the road surface, thereby preventing pedestrians and vehicles from suffering secondary injuries. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0014] like Figure 1 , 2 As shown, the embodiment of the utility model provides a new type of anti-fall sound barrier, which includes several columns 1 arranged in sequence and sound barrier unit panels 2 inserted between adjacent columns 1. The columns are arranged in rows at a certain interval and fixed on both sides of the road. The columns are H-shaped steel columns, and the sound barrier unit panels 2 are inserted between adjacent columns 1. The sound barrier unit panel 2 includes an outer shell 6 and a sound absorbing component located in the outer shell. The sound absorbing component includes a sound absorbing layer 4 and a sound insulating layer 5. The sound absorbing layer 4 is a sound absorbing material layer wrapped by non-woven fabric. The sound insulating layer 5 is a dense solid structure, generally selected from fiber cement board or galvanized steel plate, etc. The sound absorbing layer 4 and the sound insulating layer 5 are bonded and fixed together. The shell 1 includes a panel, a back panel, an upper side panel and a lower side panel. In order to improve the fatigue resistance and extend the service life, the shell is an integrally formed structure, which is formed by bending a metal plate. It also includes a cross bar 3, which is arranged at the upper end of the sound barrier unit plate and located on the lower side of the upper side plate. It is fixed to the sound absorbing component through a bow-shaped sleeve 31. The bow-shaped sleeve is adapted to the shape of the upper side surface. The length of the cross bar 3 is slightly larger than the width of the sound barrier unit plate, and the ends of the sound barrier unit plate are exposed at both ends. The shape of the end plates at both ends of the sound barrier is provided with an adapting structure for exposing the cross bar. When assembled, the two ends of the cross bar 3 on the sound barrier unit plate 2 are placed in the receiving grooves of the adjacent H-shaped steels and support the inner side of the H-shaped steel. The sound barrier unit plates 2 are stacked up and down to form a sound insulation barrier. The cross bar 3 is a cement concrete cylinder or a hollow metal cylinder.

[0015] The strength of the cross bar 3 is higher than that of the sound barrier unit plate 2. The cross bar is combined with the columns to form a fence structure, and its impact resistance is far better than that of a single screen body. When the impacting object is smaller than the distance between the upper and lower cross bars, the instantaneous impact force will cause the sound barrier unit plate to bend and deform. The sound barrier unit plate cannot withstand the impact and detaches from the columns, effectively alleviating the impact force. The cross bar is still between the columns, and the detached sound barrier unit plate rotates around the cross bar without falling on the road, avoiding secondary injury.

[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.
