Description

Technical Field

[0001] The utility model relates to the field of sound barriers, in particular to an integrated bending-molded metal sound barrier unit plate. Background Art

[0002] As an effective facility for sound insulation and noise reduction, sound barriers are widely used in high-speed railways, highways, rail transit, and municipal highways. With the commissioning of a large number of transportation construction projects, the noise problem along the line has become one of the serious pollutions that affect people's quality of life. Therefore, building sound barriers is the most effective way to solve the noise nuisance along the transportation line. Metal sound barriers have been tested and developed in practice.

[0003] At present, most metal sound barriers are thin-shell structures composed of face plates and back plates, which are fixed with blind rivets. Blind rivets are made of aluminum alloy and have poor fatigue performance. As the use time of the sound barrier increases, the blind rivets are prone to failure, which will cause the unit panel structure to fail, making it impossible to achieve the actual function of the sound barrier.

[0025] 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.

[0026] like Figure 1-Figure 7 As shown, this embodiment discloses an integrally bent metal sound barrier unit plate, including a plate body 1, which is bent and buckled to form a hollow main structure 2, and the bottom and top of the inner cavity of the main structure 2 are respectively provided with a bottom keel 3 and a top keel 4, and a sound-absorbing panel 5 is clamped between the bottom keel 3 and the top keel 4.

[0027] With this solution, a complete hollow shell is formed by bending and snapping the plate body 1, and the whole is connected without rivets, thus avoiding the failure of the main structure 2 due to the failure of the rivets during use, thereby extending the service life.

[0028] According to a further optimization scheme, the main structure 2 includes a panel 21, a bent bottom plate 22, a back plate 23, a bent top plate 24 and an end plate 25, the bent bottom plate 22 includes a folding plate 1 221 and a folding plate 222, the bent bottom plate 22 includes a folding plate 1 221 and a folding plate 222, and the folding plate 222 is snap-fitted and connected to the folding plate 1 221.

[0029] In this embodiment, a plurality of sound-permeable holes 211 are provided on the panel 21; one end of the folding plate 221 is connected to the bottom of the panel 21, and the other end of the folding plate 221 extends to the back panel 23 and is bent upward; one end of the folding plate 222 is connected to the bottom of the back panel 23, and the other end of the folding plate 222 is buckled on the folding plate 221; the two ends of the bent top plate 24 are respectively connected to the top of the panel 21 and the back panel 23; there are two end plates 25, one end of the end plate 25 is connected to the panel 21, and the other end extends to the back panel 23.

[0030] A further optimized solution is that a protrusion 223 is provided in the middle of the folding plate 221 along the length direction, a plurality of drainage holes 224 arranged at intervals are provided on both sides of the folding plate 221 along the length direction, a plurality of drainage holes 225 are provided on the folding plate 222 along the length direction, and the drainage holes 224 and the drainage holes 225 are arranged correspondingly up and down.

[0031] In this embodiment, the cross section of the protrusion 1 223 is an isosceles trapezoidal structure, and the cross section of the folding plate 1 is an obtuse triangle structure. By setting the protrusion 1 223, water passages are formed on both sides of the folding plate 1 221. When rainwater enters the interior of the main structure 2, it flows in the water passages and then flows to the outside of the main structure 2 through the drainage hole 1 224 and the drainage hole 2 225. By setting the protrusion 1 223, the drainage hole 1 224 and the drainage hole 2 225, the risk of the sound absorbing plate 5 being soaked is eliminated.

[0032] A further optimized solution is provided, in which the bottom keel 3 comprises a flat plate 31, the middle portion of the bottom surface of the flat plate 31 rests on the protrusion 223, and both ends of the flat plate 31 are fixedly connected with stiffening ribs 32 respectively, and the stiffening ribs 32 extend downward and rest on the folding plate 221; the top surface of the flat plate 31 is fixedly connected with two stiffening ribs 2 33 arranged at intervals, and the bottom of the sound absorbing panel 5 is clamped between the two stiffening ribs 2 33.

[0033] In this embodiment, a plurality of drainage holes 3 are arranged at intervals on both sides of the plate 1 31 along the length direction, and the drainage holes 3 are located on the side away from the two stiffening ribs 2 33. When rainwater enters the interior of the main structure 2, the rainwater can flow into the water passage through the provided drainage holes 3.

[0034] By adopting this solution, the plate 1 31 and the stiffening rib 1 32 can act as a skeleton for the main structure 2, and the stiffening rib 2 33 can be used to quickly install and disassemble the sound absorbing plate 5.

[0035] In a further optimized solution, a second protrusion 241 is provided along the length direction in the middle of the bent top plate 24. The cross section of the second protrusion 241 is an isosceles trapezoidal structure. The second protrusion 241 can play a role in diverting and guiding rainwater.

[0036] A further optimized solution is that the top keel 4 includes a flat plate 2 41, and the two sides of the top surface of the flat plate 2 41 are respectively fitted with the two sides of the bent top plate 24; four stiffening ribs 3 42 arranged in parallel and at intervals are fixed to the bottom surface of the flat plate 2 41, and the two stiffening ribs 3 42 located at the edge are respectively connected to the two ends of the flat plate 2 41, and the top of the sound absorbing panel 5 is clamped between the two stiffening ribs 3 42 located in the middle.

[0037] In this embodiment, the bottom keel 3 and the top keel 4 are both arranged throughout the length, and the materials of both are set to aluminum profiles, so that the self-weight of the bottom keel 3 and the top keel 4 is relatively small; the sound-absorbing panel 5 has a certain rigidity and is arranged throughout the length, which can provide good support for the top keel 4.

[0038] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
