Description

Technical Field

[0001] The utility model relates to the technical field of viaduct sound insulation screens, and more specifically, to a support locking mechanism for a viaduct sound insulation screen. Background Art

[0002] A sound insulation barrier, also known as a sound insulation wall, is one of the methods to relieve noise and is also the most effective method to mitigate noise from noise sources such as roads, railways, and industrial areas. Most of them are used for roads, and sound insulation barriers are also erected outside the construction site to reduce the nuisance of noise and dust to pedestrians or the vicinity.

[0003] After retrieval, the utility model patent with the publication number of CN216712797U discloses an easily assembled installation structure for a viaduct sound insulation screen, including a sound insulation screen module, a sound-reflecting board, a stable bottom plate, a connecting structure, a clamping base, a buried base, and a stabilizing base, where: the sound-reflecting board is welded above the sound insulation screen module, and the stable bottom plate is welded below the sound insulation screen module, and the connecting structure is nested on one side of the sound insulation screen module; the clamping base is embedded on the outside of the stable bottom plate, and the buried base is poured below the clamping base, and the stabilizing base is poured below the buried base; with the settings of the sound insulation screen module, the connecting structure, and the clamping base in this patent, sound can be effectively isolated and installed quickly.

[0004] However, the above patent still has the following deficiencies: Although the sound insulation screen can be clamped in the clamping base for fixation and can only be inserted from both sides of the clamping base, when one sound insulation screen in the middle of multiple sound insulation screens is damaged and needs to be replaced, multiple sound insulation screens need to be disassembled, and the practicability is poor; in addition, after the sound insulation screen is installed in the clamping base, it is not fixed, which is not conducive to ensuring the stability of the installation of the sound insulation screen. Therefore, we propose a support locking mechanism for a viaduct sound insulation screen. Summary of the Utility Model
