Description
Technical Field
[0001] This utility model relates to the field of road noise barrier technology, and more specifically, to a noise barrier. Background Technology
[0002] Sound barriers are primarily used for noise reduction and sound insulation of highways, expressways, elevated roads, and other noise sources. They are divided into reflective sound barriers that provide pure sound insulation, and composite sound barriers that combine sound absorption and sound insulation; the latter is a more effective sound insulation method. Sound barriers are wall-like structures erected beside railways and highways to reduce the impact of traffic noise on nearby residents. Sound walls are also called noise barriers. A sound barrier is a structure inserted between a sound source and a receiver that significantly attenuates sound wave propagation, thereby reducing the noise impact in a certain area where the receiver is located. They are categorized into traffic noise barriers, equipment noise reduction barriers, and industrial plant boundary noise barriers. Highways and expressways are where all types of sound barriers are most commonly used.
[0003] Existing sound barriers generally consist of columns and sound barrier unit panels inserted between the columns. The columns are usually made of H-shaped steel, and the sound barrier unit panels are inserted between adjacent steel columns. However, this connection method is not stable enough and is prone to loosening. When vehicles pass by, it will cause collision noise between the sound barrier unit panels and the columns. Therefore, it is necessary to add multiple connectors between the sound barrier unit panels and the columns, which makes installation inconvenient and increases the amount of bolt tightening work. Utility Model Content
[0004] The purpose of this invention is to provide a sound barrier to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A sound barrier includes a foundation component embedded below ground, a connecting component installed above the foundation component, a barrier component installed on the connecting component, and a barrier component including a foamed aluminum barrier screen and slots. The bottom of the foamed aluminum barrier screen has two symmetrically distributed slots, and adjacent foamed aluminum barrier screens are connected by the connecting component. The distance between adjacent connecting components is 4 meters.
[0006] Preferably, the connecting assembly includes an H-shaped steel column, a back groove, locking holes, ribs, locking posts, a base, locking plates, inner columns, a connecting rod, a top plate, pressure plates, and a top nut. The rear side wall of the H-shaped steel column has several back grooves and locking holes evenly distributed vertically. The locking holes are located inside the back grooves. Ribs are engaged inside the back grooves. Two locking posts are fixedly connected to the front side wall of the ribs. A base is installed below the H-shaped steel column. Two symmetrically distributed locking plates and an inner column are fixedly connected to the top of the base. A connecting rod is fixedly connected to the top of the inner column. A top plate is inserted into the top of the connecting rod. Two symmetrically distributed pressure plates are fixedly connected to the bottom of the top plate. A top nut is threaded onto the circumferential surface of the connecting rod.
[0007] By adopting the above technical solution, the top plate uses a pressure plate to press the foam aluminum barrier screen vertically downward to ensure vertical installation. The connecting rod connects the top plate and the inner column and is locked with a top nut. On the back, ribs are used to press tightly against the back of the foam aluminum barrier screen and to snap the H-shaped steel columns on both sides together, thereby increasing the stability between two adjacent H-shaped steel columns.
[0008] Preferably, the card plate is located on the left and right sides of the inner column, and the foam aluminum barrier screen body is connected to the H-shaped steel column through the card plate and the card slot.
[0009] By adopting the above technical solution, during the process of pressing the foam aluminum barrier screen down on the top plate, the slot under the foam aluminum barrier screen engages with the card plate, thereby preventing the foam aluminum barrier screen from being misaligned.
[0010] Preferably, there are two H-shaped steel columns, which are symmetrically distributed on the left and right sides of the inner column, and the pressure plate is located inside the H-shaped steel column.
[0011] By adopting the above technical solution, the bottom of the two H-shaped steel columns clamps the inner column inside, which increases the stability of the bottom of the two H-shaped steel columns.
[0012] Preferably, the H-shaped steel column and the base are connected by bevel welding, the weld quality is Grade I, and the surface of the H-shaped steel column is protected against corrosion by hot-dip galvanizing and powder coating.
[0013] By adopting the above technical solutions, in surface corrosion protection, the hot-dip galvanizing thickness is greater than 86μm and the spray coating thickness is greater than 40μm, so as to achieve the corrosion protection effect.
[0014] Preferably, the basic component includes a pre-embedded steel plate, pre-embedded screws, and pre-embedded nuts. Several pre-embedded screws are fixedly connected to the top of the pre-embedded steel plate, and pre-embedded nuts are threaded onto the circumferential surface of the pre-embedded screws. The pre-embedded steel plate is fixedly connected to the base through the pre-embedded screws and pre-embedded nuts.
[0015] By adopting the above technical solution, the pre-embedded steel plate is embedded below the ground and connected and fixed to the base using pre-embedded screws and pre-embedded nuts, thereby fixing the H-shaped steel column.
[0016] Compared with the prior art, the beneficial effects of this utility model are: 1) The sound barrier uses aluminum foam as the core material. Its porous structure can effectively absorb mid-to-high frequency sound waves, thereby reducing noise. The aluminum foam barrier screen is connected to the column by a snap-fit, and the pressure plate on the top is used to snap the aluminum foam barrier screen onto the base. Ribs on the back are used to snap the columns on both sides, thereby increasing the stability between two adjacent columns and making the connection of the aluminum foam barrier screen more stable.
[0017] 2) The barrier components, connecting components and foundation components are all prefabricated in the factory and then transported to the site for assembly, which shortens the construction period. Moreover, the splicing adopts the snap-fit method, which reduces the amount of bolts and welding used on site, reduces the installation risk, and makes the installation more convenient.

A base 206 is installed below the H-shaped steel column 201. Two symmetrically distributed locking plates 207 and an inner column 208 are fixedly connected to the top of the base 206. A connecting rod 209 is fixedly connected to the top of the inner column 208. A top plate 210 is inserted into the top of the connecting rod 209. Two symmetrically distributed pressure plates 211 are fixedly connected to the bottom of the top plate 210. A top nut 212 is threaded onto the circumferential surface of the connecting rod 209.
[0023] The top plate 210 uses the pressure plate 211 to press the foam aluminum barrier screen 101 vertically downward to ensure vertical installation. The connecting rod 209 connects the top plate 210 and the inner column 208 and locks it with the top nut 212. On the back, the rib plate 204 is used to press against the back of the foam aluminum barrier screen 101 and to snap the H-shaped steel columns 201 on both sides, thereby increasing the stability between two adjacent H-shaped steel columns 201.
[0024] The card plate 207 is located on the left and right sides of the inner column 208. The foam aluminum barrier screen 101 and the H-shaped steel column 201 are connected by the card plate 207 and the card slot 102.
