Description

Technical Field

[0001] The present application relates to the field of sound barrier equipment, and in particular to a sound barrier that is easy to install. Background Art

[0002] A sound barrier is a soundproof facility. In order to block the direct sound between the sound source and the receiver, a facility is inserted between the sound source and the receiver, so that the sound wave propagation has a significant additional attenuation, thereby reducing the noise impact in a certain area where the receiver is located. Sound barriers are mainly used outdoors on highways and elevated roads. As highway traffic noise pollution becomes increasingly serious, sound barriers are usually used to reduce traffic noise.

[0003] Existing sound barriers are generally fixed with bolts. During installation, the I-beam steel needs to be installed on the anchor bolts on the concrete pier in advance, and then a crane or elevator is used to insert multiple barrier panels one by one from above into the slots between the I-beam steels and fix them. This assembly process requires climbing, which is prone to danger and requires special equipment to assist in installation. The cost of installation and maintenance is high. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the present application provides a sound barrier that is easy to install.

[0005] The present application provides a sound barrier that is easy to install and adopts the following technical solution:

[0006] A sound barrier that is easy to install, comprising a cement base fixedly arranged on a road surface, a plurality of vertically fixed columns on the cement base, and a barrier plate arranged between adjacent columns; a side surface of the column is provided with an embedding groove, and a plurality of metal pipes are fixedly arranged on the embedding groove; another opposite side surface of the column is provided with a right-angle groove, and a positioning plate is hinged on the right-angle groove, and positioning holes are provided on the positioning plate and the column;

[0007] A plurality of shaft rods for being inserted into the metal tube are fixedly arranged on the side edge of the barrier plate, and the other side edge of the barrier plate is used for being clamped on the right-angle groove.

[0008] A further technical solution is that when the positioning plate is flush with the surface of the column, the width between the positioning plate and the column is equal to the width of the barrier plate.

[0009] A further technical solution is that the barrier plate is provided with a through hole matching the positioning hole.

[0010] A further technical solution is that the barrier plate comprises a lower screen plate, a middle screen plate and an upper screen plate which are independent of each other.

[0011] This application has the following beneficial technical effects:

[0012] By arranging a metal tube and a positioning plate on the column, when installing the barrier plate, one side of the barrier plate can be inserted into the metal tube, and the other side can be clamped between the positioning plate and the right-angle groove, thereby improving the safety and convenience of the installation of the barrier plate.

[0017] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0018] The present application embodiment discloses a sound barrier that is easy to install. Figure 1~Figure 3 A sound barrier that is easy to install includes a cement base 1 fixed on the road surface, a plurality of columns 2 vertically fixed on the cement base 1, and a barrier plate 3 arranged between adjacent columns 2; a side surface of the column 2 is provided with an embedding groove 21, and a plurality of metal tubes 23 are fixedly provided on the embedding groove 21; the other opposite side surface of the column 2 is provided with a right-angle groove 22, and a positioning plate 24 is hinged on the right-angle groove 22, and positioning holes 25 are provided on the positioning plate 24 and the column 2.

[0019] A plurality of shafts 31 for being inserted into the metal tube 23 are fixedly disposed on the side of the barrier plate 3 , and the other side of the barrier plate 3 is used for being clamped on the right-angle groove 22 .

[0020] When the positioning plate 24 is flush with the surface of the column 2, the width between the positioning plate 24 and the column 2 is equal to the width of the barrier plate 3, so that the barrier plate 3 can be smoothly embedded in the second positioning groove.

[0021] The cement base 1 can withstand the impact of vehicles and reduce the replacement frequency of the barrier plate 3. During installation, multiple columns 2 are arranged at equal intervals. First, multiple columns 2 are fixed to the cement base 1 by anchor bolts, and then the shaft 31 on the barrier plate 3 is inserted into the metal tube 23 on the column 2. At this time, the barrier plate 3 can rotate along the shaft 31. After the positioning plate 24 on the adjacent column 2 is opened, the side of the barrier plate 3 away from the shaft 31 can be embedded into the right-angle groove 22, and finally the positioning plate 24 is closed and fixed by bolts through the positioning hole 25. This can avoid the installation personnel from climbing up to install, thereby improving the safety and convenience of installing the barrier plate 3.

[0022] The barrier plate 3 is provided with a through hole 32 that matches the positioning hole 25. When the barrier plate 3 is inserted into the right-angle groove 22 and the positioning plate 24 abuts against the barrier plate 3, the positioning hole 25 and the through hole 32 are opposite to each other, and the positioning plate 24 and the barrier plate 3 can be fixed by bolts to improve the structural strength.

[0023] Furthermore, the barrier plate 3 includes a lower barrier plate 33, a middle barrier plate 34 and an upper barrier plate 35 which are independent of each other. Correspondingly, three positioning plates 24 are also provided on the column 2. When a barrier plate 3 is damaged and needs to be replaced, the damaged barrier plate 3 can be directly replaced, which has high maintenance efficiency and low installation cost.

[0024] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
