Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation walls, in particular to a sound insulation wall for rail transit. Background Art

[0002] Sound insulation walls (sound barriers) are mainly used for noise reduction of highways, elevated composite roads and other noise sources. It refers to a wall-like structure set beside railways and roads to reduce the impact of traffic noise on nearby residents. Sound insulation walls are also called sound barriers.

[0003] The existing sound insulation wall is an integrally formed structure, which requires workers to install the frame and sound insulation wall panels at the location where the wall is needed. After the later construction is completed, the user also needs to conduct large-scale cleaning and sweeping of the operation site, which is rather inconvenient.

[0004] Therefore, we propose a sound insulation wall for rail transit. Content of the Utility Model

The two groups of second mounting plates are both arranged horizontally. The right side wall surfaces of the two groups of second mounting plates are fixedly installed with a first mounting plate arranged vertically. The first mounting plate and the two groups of second mounting plates are connected in a detachable manner. The wall installation frame is movably installed between the wall surfaces of the two groups of second mounting plates that are close to each other. The distance between the wall installation frame and the two groups of second mounting plates is mutually adapted. The sound insulation wall assembly further includes a limiting frame and a sound insulation wall panel. The limiting frame is in a shape of a rectangle with a hollow center. The sound insulation wall panel is fixedly installed inside the limiting frame. The limiting frame and the sound insulation wall panel are both arranged on the front side wall surface of the wall installation frame. The wall surfaces of the two groups of second mounting plates that are close to each other are both provided with limiting connecting grooves that can be used for positioning. The two groups of limiting connecting grooves are both distributed at equal intervals.

[0007] Preferably, a second installation connecting groove that can be used for limiting is opened on the front side wall surface of the wall installation frame. The inside of the second installation connecting groove is adapted to the outer wall of the limiting frame. A first installation connecting groove that can be used for limiting is opened on the rear side wall surface of the second installation connecting groove. The inside of the first installation connecting groove is adapted to the outer wall of the sound insulation wall panel.

[0008] Preferably, the sound insulation wall panel is movably clamped into the inside of the first installation connecting groove. The outer wall of the limiting frame is movably clamped into the inside of the second installation connecting groove. A positioning threaded rod that can be used for limiting is arranged on the front side wall surface of the limiting frame.

[0009] Preferably, the outer wall of the positioning threaded rod movably penetrates the front and rear walls of the limiting frame, the positioning threaded rod and the second installation connecting groove are threadedly connected together, and the front side wall of the positioning threaded rod is provided with an auxiliary connecting groove to facilitate its rotation.

[0010] Preferably, a connecting through groove is provided on the front side wall surface of the limiting frame for facilitating its disassembly, and evenly distributed thread grooves are provided inside the connecting through groove.

[0011] Preferably, the upper and lower wall surfaces of the wall mounting frame are fixedly mounted with position limiting clips, and the adjacent wall surfaces of the two sets of second mounting plates are provided with position limiting slots.

[0012] Preferably, the outer walls of the two groups of limit card strips are mutually adapted to the interiors of the two groups of limit card slots, and the two groups of limit card strips are movably inserted into the interiors of the limit card slots on the same side.

[0013] Beneficial Effects

[0014] The utility model provides a rail transit sound insulation wall, which has the following beneficial effects:

[0015] (1) A rail transit soundproof wall. During the use of the utility model, during installation, the first mounting plate is first fixedly mounted on the vertical wall of the location where it is required to be used, and then two sets of second mounting plates are fixedly mounted together with the first mounting plate. Through the cooperation of two sets of limiting connecting grooves and positioning screws, the two sets of second mounting plates are respectively fixedly mounted on the ground and the top wall. Finally, a set of soundproof wall components is placed between the two sets of second mounting plates, and the soundproof wall components and the two sets of second mounting plates are fixedly mounted together. In this way, the soundproof wall components are placed one by one between the two sets of second mounting plates to complete the overall operation, which is simple and convenient to operate.

[0016] (2) A rail transit sound insulation wall. During use, the utility model can limit the sound insulation wall assembly by limiting the position between the limiting card strip and the limiting card slot. When fixing the sound insulation wall assembly, there is no need to support the sound insulation wall assembly, which is convenient for installation. In addition, the positioning threaded rod can be disassembled, and the limiting frame and the sound insulation wall panel can be disassembled and replaced from the inside of the first installation connecting groove and the second installation connecting groove. When taking out the limiting frame and the sound insulation wall panel, the bolt and the connecting through groove can be threadedly connected, so that the bolt will move backward and conflict with the front side wall of the second installation connecting groove. The limiting frame can be pushed out from the inside of the second installation connecting groove, which is convenient for disassembly of the limiting frame and the sound insulation wall panel.
