Description

Technical Field

[0001] This utility model relates to the field of road traffic noise control, and in particular to a rainwater diversion metal barrier unit panel. Background Technology

[0002] When rail transit and highways pass through residential areas, sound barriers have become the main way to control road noise in order to reduce traffic noise disturbance to residents on both sides. At present, the sound-absorbing materials of metal sound barriers are mostly rock wool or glass wool. Although they have a high water repellency rate, in areas with a lot of rain, the sound-absorbing materials of metal sound barriers are directly affected by long-term immersion in rainwater, which directly affects the overall performance of the metal sound barriers and causes them to fail to achieve their actual function. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a rainwater diversion metal barrier unit plate. This utility model adopts the following technical solution:

A plurality of sound-absorbing holes are disposed on one side wall of the unit panel shell. The sound-absorbing holes are elongated and arranged along the length direction of the unit panel shell. A rainwater diversion channel is disposed above each sound-absorbing hole. The length of the rainwater diversion channel is greater than the length of the sound-absorbing hole. The rainwater diversion channel is fixed to the unit panel shell. The bottom of the rainwater diversion channel has a slope that is higher in the middle and lower on both sides in the length direction, and a slope that is higher on the inner side and lower on the outer side in the width direction.

[0005] Preferably, the unit panel shell includes an integrally bent side plate one, a top plate, a side plate two, and a bottom plate. The side plate one, the top plate, the side plate two, and the bottom plate are connected end to end to form a screen frame. The two ends of the screen frame are provided with end caps. The sound-absorbing holes are provided on the side plate two.

[0006] Preferably, the top plate has a protrusion along its length, and the bottom plate has a groove along its length; when two adjacent unit plate shells are assembled vertically, the groove and the protrusion are engaged.

[0007] Preferably, the bottom edge of the unit plate shell is provided with inter-plate adhesive strips along its length.

[0008] Preferably, the unit plate housing has inter-plate strips at both ends of each side wall.

[0009] Preferably, the sound-absorbing material is rock wool or glass wool.

[0017] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 As shown, this embodiment discloses a rainwater diversion metal barrier unit panel, including a unit panel shell 1. The unit panel shell 1 is provided with a sound-absorbing material, which can be rock wool or glass wool. Several sound-absorbing holes 2 are provided on one side wall of the unit panel shell 1. The sound-absorbing holes 2 are elongated and arranged along the length direction of the unit panel shell 1. A rainwater diversion channel 3 is provided above each sound-absorbing hole 2. The length of the rainwater diversion channel 3 is greater than the length of the sound-absorbing hole 2. The rainwater diversion channel 3 is fixed to the unit panel shell 1 by rivets. The bottom of the rainwater diversion channel 3 is a slope with a high middle and low sides in the length direction and a slope with a high inner side and low outer side in the width direction.

[0019] The rainwater diversion channel 3 allows rainwater to flow along the channel to both ends of the sound absorption hole 2, reducing the risk of the sound-absorbing material inside the sound barrier being eroded by rainwater, ensuring the normal sound absorption and insulation of the metal sound barrier in rainy weather, and improving the stability, durability and service life of the sound barrier's sound absorption performance.

[0020] The unit panel housing 1 mainly includes a screen frame 106 and a head plate 105. The screen frame 106 forms a hollow shell structure, ensuring overall stability. The head plate 105 is fixed to the ends of the screen frame 106 by rivets. The screen frame 106 is formed by bending a single sheet of material, and its structure mainly consists of side plate 101, top plate 102, side plate 103, and bottom plate 104. Side plate 101, top plate 102, side plate 103, and bottom plate 104 are connected end to end to form the screen frame 106. In this embodiment, side plate 103 faces the road, and the sound-absorbing holes 2 are set on side plate 103.

[0021] In this embodiment, a protrusion 107 is provided on the top plate 102 along its length, and a groove 108 is provided on the bottom plate 104 along its length. The protrusion 107 and the groove 108 are also formed by bending. When two adjacent unit plate shells 1 are assembled vertically, the protrusion 107 on the lower unit plate shell 1 is embedded in the groove 108 on the upper unit plate shell 1.

[0022] In this embodiment, inter-panel adhesive strips 4 are laid along the length of the bottom edge of the unit panel housing 1. Simultaneously, inter-panel adhesive strips 5 are provided at both ends of each sidewall of the unit panel housing 1. The inter-panel adhesive strips 5 can be fixed to the unit panel housing 1 with rivets. The inter-panel adhesive strips 4 prevent noise leakage between the metal sound barrier unit panels, and the inter-panel adhesive strips 5 prevent noise leakage between the metal sound barrier unit panels and the supporting columns, effectively improving the sound absorption and insulation performance of the sound barrier.

[0023] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
