AI Technical Summary
Existing metal sound barrier unit panels are at risk of falling off during installation, especially when using inorganic non-metallic sound-absorbing materials such as ceramics, ceramsite, and perlite. The insufficient tensile strength of the hanging ear structure leads to a decrease in safety and increases production costs and installation complexity.
Fall protection holes are provided on the unit plate crossbeams and the shell. Crossbeam keyways are formed by drilling or punching, and steel wire ropes are fixed through the fall protection holes of the crossbeams and the shell, which simplifies the installation process and improves the stability.
This approach achieves safety and reliability for metal sound barrier unit panels, simplifies the production process, reduces material costs, and improves installation efficiency and safety.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal sound barrier unit panels, and in particular to a metal sound barrier unit panel with a fall-prevention structure. Background Technology
[0002] Metal sound barrier panels are widely used in railways and urban rail transit to alleviate noise pollution for urban and rural residents and provide them with a better living environment. Metal sound barrier panels are characterized by high sound insulation, high sound absorption coefficient, high strength, strong weather resistance, aesthetic appeal, and convenient installation and maintenance. However, during installation and maintenance, there is a risk of metal sound barrier panels falling off urban overpasses. Falling panels could cause traffic hazards, injure pedestrians, and damage facilities.
[0003] Currently, the main method to prevent metal sound barrier unit panels from falling off is to install hanging ears on the side sealing plates of the metal unit panels. These ears are riveted to the side sealing plates, and then anti-fall steel wire ropes are passed through the ears to hold the unit panels in place. However, this structure has relatively low tensile strength, and there is still a risk that the hanging ears may fall off and fail to hold the panel in place. This is especially true for metal sound barrier unit panels with high surface density that use inorganic non-metallic sound-absorbing materials such as ceramics, ceramsite, and perlite; using hanging ears significantly reduces structural safety. The addition of pre-installed steel wire ropes during unit panel production, the use of more anti-fall materials increasing costs, and the corresponding increase in installation and locking procedures also add to the overall process. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a safe, reliable, simple to manufacture, easy to install, and cost-effective metal sound barrier unit panel with an anti-fall structure.
[0005] The technical solution of the metal sound barrier unit panel with anti-fall structure provided by this utility model is as follows:
[0006] A metal sound barrier unit panel with a fall protection structure includes a unit panel crossbeam (01), a unit panel shell (02), and a unit panel side sealing plate (03). The unit panel crossbeam (01) and the unit panel shell (02) are inserted into the unit panel side sealing plate (03). A reinforcing rib plate (05) is provided on the unit panel crossbeam (01). The unit panel side sealing plate (03) has a reserved crossbeam insertion keyway (07). The crossbeam reinforcing rib plate (05) passes through the crossbeam insertion keyway (07). The unit panel crossbeam (01) has a crossbeam fall protection hole (04). The unit panel shell (02) has a shell fall protection hole (06). The sound barrier fall protection steel wire rope passes through the crossbeam fall protection hole (04) and the shell fall protection hole (06) for connection and fall protection.
[0007] Furthermore, the crossbeam anti-fall hole (04) and the shell anti-fall hole (06) are formed by drilling or stamping.
[0008] The implementation of this utility model has the following technical effects:
[0009] This utility model discloses a metal sound barrier unit panel with a fall-prevention structure. The fall-prevention steel wire rope passes through the fall-prevention holes in the crossbeam and the unit panel shell for connection and fall prevention. The fall-prevention structure has excellent performance and will not detach. The keyway for the crossbeam insertion is reserved in the side sealing plate of the unit panel, which does not affect the mechanical properties of the crossbeam. The unit panel is assembled by inserting the crossbeam into the side sealing plate and the unit panel shell. The keyway for the crossbeam insertion in the side sealing plate makes the installation process simple and easy to operate. Simultaneously, the wire rope insertion process during construction and installation is simple and easy to operate. Attached Figure Description

[0015] The present invention will now be described in detail with reference to the embodiments and accompanying drawings. It should be noted that the described embodiments are only intended to facilitate the understanding of the present invention and do not constitute any limitation thereof.
[0016] See Figures 1 to 4As shown, this embodiment provides a metal sound barrier unit panel with a fall protection structure, including a unit panel crossbeam 01, a unit panel shell 02, and a unit panel side sealing plate 03. The unit panel crossbeam 01 and the unit panel shell 02 are inserted into the unit panel side sealing plate 03. A reinforcing rib plate 05 is provided on the unit panel crossbeam 01. The unit panel side sealing plate 03 has a pre-reserved crossbeam insertion keyway 07, through which the crossbeam reinforcing rib plate 05 passes. The unit panel crossbeam 01 has a crossbeam fall protection hole 04, and the unit panel shell 02 has a shell fall protection hole 06. The sound barrier fall protection steel wire rope passes through the crossbeam fall protection hole 04 and the shell fall protection hole 06 for connection and fall protection. The fall protection structure has excellent performance and will not detach. Further, the unit panel side sealing plate 03 is first formed by drilling or stamping sheet metal to form the crossbeam insertion keyway 07, and then bent to form the side sealing plate assembly edge. The pre-reserved keyway 07 for the crossbeam in the side sealing plate of the unit panel does not affect the mechanical properties of the crossbeam. While maintaining the installation effect of the side sealing plate, it protects the mechanical properties of the crossbeam. The anti-fall method of the sound barrier unit panel is reliable, the wire rope insertion construction process is simple, and it improves construction and installation efficiency. The process is simple and easy to operate.
