Two oppositely arranged steel truss columns 103 are provided on top of the corridor surface steel beam 104. A corridor roof steel beam 101 is provided on top of the steel truss columns 103. Transport equipment 100 is provided in the space formed by the corridor roof steel beam 101, the steel truss columns 103, and the corridor surface steel beam 104. Sound insulation panels 200 are provided on the outer sides of the corridor roof steel beam 101, the steel truss columns 103, and the corridor surface steel beam 104 away from the transport equipment 100. The sound insulation panels 200 include, from the outside to the inside, a galvanized steel plate 203, a damping sound insulation felt 202, glass sound-absorbing cotton 201, an alkali-free hydrophobic glass fiber cloth 208, and a galvanized perforated plate 207.

[0018] The galvanized steel plate 203 adopts 1.0 mm YX28-205-820 type steel plate to ensure that the outer side of the structure is beautiful and neat. The damping sound insulation felt 202 adopts 2 mm thickness and is used for sound insulation and fixing the glass sound-absorbing cotton 201. The glass sound-absorbing cotton 201 adopts 100 mm thickness and is used for sound absorption and noise reduction. The alkali-free hydrophobic glass fiber cloth 208 adopts 0.2 mm and is used to fix the glass sound-absorbing cotton 201 on the inside and ensure the waterproof effect of the glass sound-absorbing cotton 201. The galvanized perforated plate 207 adopts 0.6 mm, its perforation rate is ≧20%, and the aperture is ≧3 mm.

[0019] In this embodiment, the sound insulation panels 200 on the outside of the corridor roof steel beams 101 are connected to the roof purlins 206 using galvanized purlins 205 via self-tapping screws 204. The steel truss columns 103 are connected to the wall purlins 209 using galvanized purlins 205 via self-tapping screws 204. The bottom of the corridor surface steel beams 104 is connected to the steel plate 106 via butt welding. The sound insulation panels 200 on the outside of the corridor surface steel beams 104 are fixed to the top of the steel plate 106. The width of the steel plate 106 is 100 mm, and its thickness is consistent with the flange thickness of the steel truss columns 103.

[0020] Galvanized purlins 205 are provided to facilitate the installation of the sound insulation board 200 and bear the external wind load and the deadweight of the sound insulation board 200. The sound insulation board 200 is fixed by self-tapping screws 204, making the steel corridor closed structure simple to manufacture, convenient to construct, and easy to disassemble.

[0021] In this embodiment, the connection gap between the sound insulation board 200 on the outside of the steel truss column 103 and the sound insulation board 200 on the outside of the corridor surface steel beam 104 is densely filled with foam sealant 105, and the connection between the corridor top steel beam 101 and the steel truss column 103 is provided with a reinforcing rib 102.

[0022] The foam sealant 105 is used for dense filling to enhance the sealing of the structure, prevent the leakage of material dust during transportation, reduce dust pollution, and protect the surrounding ecological environment. Reinforcement ribs 102 are provided to improve the stability and safety of the structure.

[0023] Working process and principle: When the device is in use, according to the design requirements, the corridor surface steel beam 104 is installed to ensure its stability. The corridor surface steel beam 104 is used as the base, and two oppositely arranged steel truss columns 103 are fixed on it to form a stable support structure. The corridor top steel beam 101 is connected to the top of the steel truss column 103, and together with the corridor surface steel beam 104 and the steel truss column 103, a rectangular frame is formed. In this frame space, the transportation equipment 100 is installed to meet the material transportation needs. 01. A multi-layered sound insulation board 200 is installed on the outside of the steel truss column 103 and the corridor surface steel beam 104. The sound insulation board 200 is protected by a galvanized steel plate 203 as the outer layer, and the inner layer is composed of damping sound insulation felt 202, glass sound-absorbing cotton 201, alkali-free hydrophobic glass fiber cloth 208 and galvanized perforated plate 207, forming an efficient sound insulation barrier. It can effectively reduce the noise generated by multiple belt conveyors during material transportation, ensuring that the transportation noise is reduced by 30 decibels, solving the long-standing problem of corridor transportation passing through residential areas. To address the noise pollution problem caused by nearby residents, the sound insulation board 200 on the outside of the corridor top steel beam 101 is fixed by self-tapping screws 204 through galvanized purlins 205 and roof purlins 206. The sound insulation board 200 on the outside of the steel truss column 103 is also fixed by self-tapping screws 204 through galvanized purlins 205 and wall purlins 209. The steel plate 106 is welded to the bottom of the corridor surface steel beam 104, and the sound insulation board 200 on the outside of the corridor surface steel beam 104 is fixed to the top of the steel plate 106. At the same time, the sound insulation board 200 on the outside of the steel truss column 103 is fixed by self-tapping screws 204. The connection gap between the sound insulation board 200 on the outside of the corridor surface steel beam 100 and the corridor surface steel beam 104 is densely filled with foam sealant 105 to further improve the sound insulation effect. While performing sound insulation and sealing, it also eliminates dust pollution generated during material transportation, ensuring the life and health of nearby residents and organisms, reducing dust pollution, and protecting the ecological environment. Reinforcement ribs 102 are set at the connection between the corridor top steel beam 101 and the steel truss column 103 to enhance the overall stability and bearing capacity of the structure.
