Description

Technical Field

[0001] The utility model relates to a noise protection device, in particular to a spliced ​​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 roads 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 expressways are the places where various types of sound barriers are used the most.

[0003] Sound barriers are generally assembled by inserting sound barrier unit panels between adjacent columns. The columns are generally H-shaped steel columns. The defect of this structure is that it has high requirements on the size specifications of the sound barrier unit panels. The sound barrier unit panels need to be customized according to the installation spacing on site. Sometimes due to installation or measurement errors, the sound barrier unit panels customized according to feedback may not be installed, which not only wastes materials but also causes delays in work and time. Therefore, how to design a sound barrier that can adapt to various errors 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 spliced ​​sound barrier which can adapt to various construction errors.

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

[0006] A spliced ​​sound barrier, comprising a plurality of columns arranged in sequence and a sound barrier unit plate inserted between the columns, the sound barrier unit plate comprising an outer shell and a sound absorbing component located in the outer shell, the outer shell comprising a panel, a back plate, an upper side plate, a lower side plate, a left side plate and a right side plate, characterized in that the columns comprise a bottom plate and two wing plates arranged parallel to each other and fixed on the bottom plate, the left side plate and the right side plate are concave-convex structures that cooperate with each other, and the upper side plate and the lower side plate are concave-convex structures that cooperate with each other.

[0007] Preferably, reinforcing ribs are provided on both sides of the two wing plates.

[0008] Preferably, the left side panel is an aluminum profile with a concave V-shaped structure, and the right side panel is an aluminum profile with a convex V-shaped structure, and the left side panel and the right side panel are respectively fixed to the left and right ends of the sound barrier unit panel.

[0009] Preferably, the left side panel is an aluminum profile with a concave V-shaped structure, and the right side panel is an aluminum profile with a convex V-shaped structure, and both the left side panel and the right side panel are formed by bending the end portions of the sound barrier unit panel.

[0010] Preferably, the upper ends of the left side plate and the right side plate are both provided with protrusions, and the lower ends of the left side plate and the right side plate are both provided with grooves matching the protrusions.

[0011] The beneficial effects of the present invention are as follows: the spliced ​​sound barrier provided by the present invention, adjacent sound barrier unit plates, including upper and lower adjacent sound barrier unit plates and left and right adjacent sound barrier unit plates, are all spliced ​​with a concave-convex structure. The web of the traditional H-shaped steel can be omitted, and only the steel containing two wing plates is used for fixing, thus avoiding the traditional structure using the H-shaped steel structure. The width of the sound barrier unit plate must match the distance between two adjacent steel sections. If the width is too large or too small, it will bring inconvenience to the construction and reduce the efficiency. The sound barrier unit plate can have a relatively large dimensional elasticity within a certain range, thereby improving the production efficiency and installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 Schematic diagram of the explosion structure of the sound barrier unit panel. DETAILED DESCRIPTION

[0014] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0015] like Figure 1-2 As shown, an embodiment of the utility model provides a spliced ​​sound barrier, which includes several columns arranged in sequence and sound barrier unit plates inserted between adjacent columns. The columns are arranged at a certain interval, and the spacing is generally selected to be 2~4m. The column 2 includes a base plate 21 and two wing plates 22 fixed on the base plate and arranged parallel to each other. Compared with traditional H-shaped steel columns, the columns of this structure omits the middle web. Due to the lack of the partition restriction of the web, the sound barrier unit plate can be infinitely extended in the lateral direction without being restricted by a fixed length of the sound barrier unit plate. In order to increase the strength, the ends are blocked to prevent the sound barrier unit plate from falling out. The columns at the two ends still use H-shaped steel columns.

[0016] The sound barrier unit panel includes an outer shell and a sound absorbing component located in the outer shell. The outer shell includes a panel 11, a back panel 12, an upper side panel 13, a lower side panel 14, a left side panel 15 and a right side panel 16. The panel 11, the back panel 12, the upper side panel 13 and the lower side panel 14 can be formed by bending a single metal plate, or by bending two metal plates and buckling them together. The left side panel 15 and the right side panel 16 are configured as mutually matching concave-convex structures, and the upper side panel 13 and the lower side panel 14 are also mutually matching concave-convex structures. Specifically, the left side panel 15 is an aluminum profile with a concave V-shaped structure, and the right side panel 16 is an aluminum profile with a convex V-shaped structure matching the left side panel 15. The left side panel 15 and the right side panel 16 are respectively fixed to the left and right ends of the sound barrier unit panel. As other structural options, the left side panel and the right side panel are both formed by bending the ends of the sound barrier unit panel into matching concave-convex structures. This structure does not need to be fixed with fixing parts. When in the assembled state, the left and right sound barrier unit panels and the upper and lower sound barrier unit panels are matched with each other in concave and convex. These mutually matched sound barrier unit panels are inserted between the columns. Each sound barrier unit panel is equivalent to a "building block". These "building blocks" form a sound barrier wall. Since the sound barrier unit panels are matched with each other in concave and convex to form a sound barrier, there is no gap between the sound barrier unit panels to prevent sound leakage. The columns only play the role of positioning and reinforcement. In order to improve the strength of the columns, reinforcing ribs 23 are provided on both sides of the two wing plates. In order to prevent the upper and lower sound barrier unit panels at the two ends of the sound barrier from detaching, protrusions are provided on the upper ends of the left and right panels, and grooves matching the protrusions are provided on the lower ends of the left and right panels. In the assembled state, the protrusions and grooves are snap-fitted with each other.

[0017] 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.
