[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] like Figure 1-Figure 11 As shown, the present embodiment discloses a metal sound barrier unit plate, comprising: a bent panel 1 and a bent back panel 2, the bent panel 1 and the bent back panel 2 are buckled together to form a main structure 3, the top of the main structure 3 is provided with two spaced protrusions 31, the bottom of the main structure 3 is provided with two spaced grooves 32, the grooves 32 correspond to the protrusions 31 one by one; the top and bottom of the inner cavity of the main structure 3 are provided with longitudinal beams 4, and a sound absorbing plate 5 is clamped between the two longitudinal beams 4; the main structure Both ends of the structure 3 are buckled with bent end sealing plates 6, and both sides of the end of the longitudinal beam 4 are respectively fitted with the corresponding bent end sealing plates 6; both sides of the end of the bent back plate 2 are provided with plate-column rubber strips 7, and the upper and lower sides of the plate-column rubber strips 7 are penetrated by fixing parts 8, which fix the bent back plate 2, the bent end sealing plates 6 and the longitudinal beam 4; the upper and lower sides of the end of the bent panel 1 are provided with locking devices 9, which lock and fix the bent panel 1, the bent end sealing plates 6 and the longitudinal beam 4.

[0034] In this embodiment, the bending panel 1 and the bending back panel 2 are fastened together without rivets, and the connection between the two is an interference fit relationship; the fixing part 8 is configured as a pull rivet, and the pull rivet can be used to fix the rubber strip 7 between the plate and column, the bending back panel 2, the bending end sealing plate 6, and the longitudinal beam 4.

[0035] By adopting this solution, the protrusion 31 set on the top of the main structure 3 and the groove 32 set on the bottom can improve the bending resistance of the main structure 3; the longitudinal beam 4 set in the inner cavity of the main structure 3 can play the role of a skeleton; the fixing parts 8 and the locking device 9 can be used to reliably connect the main structure 3, the bent end sealing plate 6 and the longitudinal beam 4; through the setting of the above-mentioned structure, the stability of the utility model can be greatly improved.

[0036] To further optimize the solution, a plurality of drainage holes 41 are provided on the longitudinal beam 4 at the bottom; when the bent end sealing plate 6 is buckled and installed, a gap is left between the bottom surface of the bent end sealing plate 6 and the bottom wall of the inner cavity of the main structure 3.

[0037] The protrusion 31 on the top of the main structure 3 can divert rainwater. When there is a lot of rainwater, it can enter the main structure 3 through the gap between the bent panel 1 and the bent back panel 2, fall to the bottom longitudinal beam 4, and then fall to the bottom wall of the inner cavity of the main structure 3 through the drainage hole 41, and finally be discharged through the gap reserved between the bent end sealing plate 6 and the bottom wall of the inner cavity of the main structure 3, eliminating the risk of the sound absorbing panel 5 being soaked in special rainy and snowy weather.

[0038] A further optimization scheme is that the middle parts of the bent panel 1 and the bent back panel 2 are provided with reinforcing grooves 10 along the length direction, and the two reinforcing grooves 10 are arranged correspondingly; both sides of the middle part of the sound absorbing plate 5 are provided with reinforcing supports 11 along the length direction, one end of the reinforcing support 11 is against the sound absorbing plate 5, and the other end of the reinforcing support 11 is against the corresponding reinforcing groove 10.

[0039] Specifically, the reinforcing groove 10 is an arc-shaped structure; the end of the reinforcing support 11 that abuts against the reinforcing groove 10 is adapted to the reinforcing groove 10; the number of reinforcing supports 11 is set to be multiple, and the multiple reinforcing supports 11 are arranged at intervals along the length direction. The reinforcing supports 11 are provided to support the sound absorbing plate 5 and the main structure 3, which can further improve the stability of the utility model.

[0040] Further optimization scheme, the bottom of the main structure 3 is connected with an inter-board rubber strip 12 along the length direction. The inter-board rubber strip 12 is arranged in a close fit with the bottom of the main structure 3, and is fixed to the bottom of the main structure 3 by rivets; the inter-board rubber strip 12 located at the groove 32 at the bottom of the main structure 3 is arranged as an inclined zigzag structure, which can increase the friction between the main structure 3 and the main structure 3, and can further improve the stability of the utility model.

[0041] Further optimizing the scheme, the locking device 9 includes a rivet nut 91 arranged in the inner cavity of the main structure 3, and the open end of the rivet nut 91 is against the longitudinal beam 4; a connecting bolt 92 is arranged on the outer side of the main structure 3, and the screw end of the connecting bolt 92 sequentially passes through the bent panel 1, the bent end sealing plate 6, and the longitudinal beam 4 and extends into the rivet nut 91, and the connecting bolt 92 is threadedly connected with the rivet nut 91; a locking nut 93 is threadedly connected to the connecting bolt 92, and the locking nut 93 is against the bent panel 1. The rivet nut 91, the connecting bolt 92 and the locking nut 93 can achieve the effect of fixing the bent panel 1, the bent end sealing plate 6 and the longitudinal beam 4.

[0042] The sound barrier unit plate of the utility model is installed between two H-shaped steel columns. One end of the rubber strip 7 between the plate and the column is rolled into a hollow cylindrical structure and abuts against the web of the H-shaped steel column. A rubber protective sleeve is installed on the nut of the connecting bolt 92, and the nut of the connecting bolt 92 abuts against the web of the steel column through the rubber protective sleeve. A flexible connection with the steel column is achieved through the rubber strip 7 between the plate and the column and the rubber protective sleeve.
