Description

Technical Field

[0001] This utility model relates to the field of highway sound barrier technology, specifically to an installation column for highway sound barriers. Background Technology

[0002] Noise pollution is generated by vehicles traveling along highways. To address this noise pollution, sound barriers are widely used along both sides of highways. Vertical sound barriers are particularly popular due to their ease of installation and mature technology.

[0003] However, when installing sound barriers, each barrier needs to be lifted above the mounting column before it can be installed into the slot on the column. This installation method is labor-intensive and inefficient.

[0004] Chinese patent CN202120355441.9 discloses "A Support Column for a Highway Noise Barrier" (publication number CN214883097U). This device includes a column body mounted on a base plate, which is positioned on top of a crash barrier. U-shaped bolts with upward-facing openings are pre-embedded within the crash barrier, parallel to the barrier. The two free ends of the U-shaped bolts penetrate the base plate and are locked with nuts. A positioning plate, closely attached to the rear side of the crash barrier, is located on the rear side of the base plate. Two positioning bolts, perpendicular to the same plane, are mounted on the crash barrier, penetrating the positioning plate and locked with nuts. However, this device has some drawbacks: the column body is I-shaped, requiring workers to lift each sound barrier section above the column body before inserting it between the columns. This installation method is labor-intensive and inefficient. Furthermore, when a lower section of the sound barrier is damaged, the entire structure must be dismantled and reinstalled, making replacement inconvenient. Utility Model Content

[0005] To address the problems of the prior art, this invention provides an installation column for highway sound barriers that eliminates the need to raise each sound barrier to the top of the installation column and allows for individual disassembly of a sound barrier, facilitating its replacement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an installation column for a highway sound barrier, comprising a base, a column fixedly connected to the base, and a back plate fixedly connected to the column, wherein symmetrically hinged pressure plates are provided on the column, and multiple pressure plates are provided, the pressure plates are arranged along the height direction of the column, and a locking plate is provided on the column for fixing the pressure plates.

[0007] With the above structural design, it is not necessary to raise each sound barrier above the mounting column, and a sound barrier can be disassembled individually, making it easy to replace the sound barrier.

[0008] Preferably, the locking plate is rotatably connected to the column, and a stop block is fixedly connected to the pressure plate. When the locking plate is rotated to a horizontal state, the locking plate contacts the stop block. An auxiliary rod for assisting in rotating the locking plate is fixedly connected to the locking plate.

[0009] With the above structural design, the locking plate can be rotated to hold the pressure plate in place and prevent it from rotating.

[0010] Preferably, a fixed shaft is fixedly connected to the column, the middle part of the locking plate is threaded onto the fixed shaft, and the end of the fixed shaft is fixedly connected to the top plate.

[0011] With the above structural design, the locking plate is connected to the column by threads, which can lock the pressure plate.

[0012] Preferably, multiple locking bolts are provided on the locking plate, and threaded holes matching the locking bolts are provided on both the column and the pressure plate.

[0013] The above structural design uses bolts to fix the locking plate and the pressure plate, resulting in a simple structure that is easy to operate.

[0014] Preferably, the upper end of the pressure plate is fixedly connected to the upper locking cylinder, and the lower end of the pressure plate is fixedly connected to the lower locking cylinder. When adjacent upper and lower locking cylinders are aligned, positioning pins are provided inside the upper and lower locking cylinders.

[0015] The above structural design allows adjacent pressure plates to be connected together, improving the overall integrity of the device.

[0016] Preferably, a reinforcing plate is provided on the base, and a triangular support plate is fixedly connected to the reinforcing plate. The support plate abuts against the outer wall of the pressure plate. Reinforcing bolts are passed through the reinforcing plate, and mounting holes matching the reinforcing bolts are opened on the base.

[0017] The above structural design can increase the support of the device for the columns and pressure plates.

[0018] Preferably, rubber pads are fixedly connected to the inner sidewalls of the back plate and the pressure plate, and the rubber pads are striped.

[0019] By adopting the above structural design, the friction between the pressure plate and the sound barrier is increased, the gap between the pressure plate and the sound barrier is reduced, and the sound barrier is prevented from falling off.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1) This device avoids raising each sound barrier above the column, reducing the labor intensity of the staff.

[0022] 2) This device can individually compress each sound barrier. When a sound barrier is damaged, it can be disassembled separately for easy replacement. Attached Figure Description
