Description

Technical Field

[0001] The utility model relates to the technical field of noise protection devices, in particular to an anti-detachment splicing type upright sound barrier. Background Art

[0002] As a key structure for road noise control, sound barriers are mainly used for sound insulation and noise reduction in bridges, highways, urban elevated roads and other noisy environments.

[0003] According to their structural form, sound barriers can be generally divided into upright sound barriers and fully enclosed sound barriers. Upright sound barriers generally include H-shaped steel and sound insulation boards arranged between adjacent H-shaped steels. The sound insulation boards are inserted between adjacent H-shaped steels. This structure is generally easy to get out of between the H-shaped steels when subjected to external force or thermal expansion and contraction. When there is an on-site installation error, one end of the sound insulation board is also easy to get out of the H-shaped steel or only partially contact the H-shaped steel. Once subjected to force, it is easy to cause the sound insulation board to get out. Utility Model Content

[0009] When the butt ends of two adjacent sound barrier unit panels are connected to a corresponding splicing column, the two V-shaped wing plates of the splicing column respectively extend into the C-shaped slots of the butt ends of the two adjacent sound barrier unit panels, and the two ends of each V-shaped wing plate respectively resist the inner wall of the C-shaped slot.

[0010] In the described C-shaped card slot, wedge-shaped strips that are integrally molded and vertically extended are provided on the inner walls of the slot on both sides of the slot opening. When the V-shaped wing plate is inserted into the C-shaped card slot, the V-shaped inner surface of the V-shaped wing plate is parallel to the inclined surfaces of the two wedge-shaped strips in the C-shaped card slot, so as to limit and support the V-shaped wing plate through the two wedge-shaped strips.

[0011] A plurality of vertically penetrating hollow holes are formed in the described wedge-shaped strip.

[0012] A rectangular ring card slot is formed on the rectangular inner wall of the described rectangular frame, and the edge portion of the sound insulation board is clamped in the rectangular ring card slot.

[0013] The described rectangular frame is a hollow structure. The rectangular frame includes a rectangular ring sealing plate and four V-shaped sealing plates. Both ends of each V-shaped sealing plate are fixedly connected to the inner wall of one side edge of the rectangular ring sealing plate, and the four V-shaped sealing plates form a rectangular ring structure and are fixedly connected. Openings are provided at the sharp corners of the four V-shaped sealing plates, and a strip-shaped concave plate that is recessed into the V-shaped sealing plate is connected to each opening. The four strip-shaped concave plates are fixedly connected to form a rectangular ring card slot.

[0014] When the height of the described splicing column is multiple times the height of the sound barrier unit board, a plurality of vertically butted sound barrier unit boards are spliced between two adjacent splicing columns.

[0015] Advantages of the present utility model:

[0016] (1). A snap connection structure of a V-shaped wing plate and a C-shaped card slot is adopted between the sound barrier unit board and the splicing column of the present utility model, effectively avoiding the problem that the sound barrier unit board disengages from the splicing column.

[0017] (2). The snap connection structure of the V-shaped wing plate and the C-shaped card slot of the present utility model makes the upright sound barrier tighter in clamping under greater force when being subjected to a lateral force, that is, the force in the extending direction of the barrier unit board, and has a good anti-disengagement effect.

[0018] (3). A wedge-shaped strip is arranged in the C-shaped card slot of the present utility model to support and limit the inserted V-shaped wing plate, so that when the upright sound barrier is stressed, the wedge-shaped strip can stably support the V-shaped wing plate, making the force more uniform, avoiding damage to the splicing column, and improving the service life of the present utility model.

[0019] (4). The rectangular frame and the wedge-shaped strip of the present utility model both adopt a hollow structure, greatly reducing the weight and manufacturing cost of the upright sound barrier, and realizing the stable support and splicing of the sound insulation board.
