Description

Technical Field

[0001] This invention relates to the field of sound barrier technology, and in particular to a sound barrier component and treatment method for expansion joints. Background Technology

[0002] A sound barrier is a facility inserted between a sound source and a receiver to significantly attenuate sound wave propagation, thereby reducing the noise impact within a certain area where the receiver is located. Such facilities are called sound barriers. They are categorized into traffic noise barriers, equipment noise reduction barriers, and industrial plant boundary noise barriers. In recent years, sound barriers have been used on municipal elevated highways, effectively reducing the impact of traffic noise on nearby buildings. The design of elevated highway sound barriers depends on the on-site embedded parts and expansion joints. The expansion joint nodes are treated to ensure the sound barrier meets expansion and contraction requirements. Current technology typically uses sound insulation panels placed between two steel columns; however, the lack of a rigid connection between the sound insulation panels and the steel columns leaves gaps, failing to achieve adequate sound insulation. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a sound barrier component for expansion joints, which can improve the sound insulation effect of the sound barrier.

[0004] According to a first aspect of the present invention, a sound barrier component at an expansion joint includes: two steel columns, a fixing plate, two rollers, a sound insulation plate, and fixing bolts. The steel columns are vertically connected to a foundation, and the two steel columns have grooves on opposite sides. The fixing plate has a first bolt hole at its center. The rollers have axles mounted at their centers, and the axles are rotatably mounted on the fixing plate. The two rollers are symmetrically installed with respect to the first bolt hole, and the rollers are embedded in corresponding grooves. Anti-detachment plates are welded to the steel columns to prevent the rollers from detaching from the grooves. The two ends of the sound insulation plate are respectively embedded in corresponding grooves, and the sound insulation plate is sandwiched between the axles and the sidewalls of the grooves. The fixing bolts pass vertically through the fixing plate and the sound insulation plate.

[0005] According to a first aspect embodiment of the present invention, a sound barrier component at an expansion joint includes a sound-insulating plate sandwiched between an axle and the sidewall of a groove. As the two steel columns approach and move away from each other, the sound-insulating plate slides between the axle and the sidewall of the groove, effectively sealing the gap between the two steel columns and preventing noise transmission through this gap. This improves the sound insulation effect of the sound barrier.

[0006] According to some embodiments of the present invention, a second bolt hole is provided in the center of the sound insulation panel, and the fixing bolt passes through the first bolt hole and the second bolt hole.

[0007] According to some embodiments of the present invention, the size of the sound insulation panel is matched with the maximum and minimum distance between the two steel columns.

[0008] According to some embodiments of the present invention, the fixing bolt is threaded with a first nut and a second nut, and the sound insulation plate is sandwiched between the first nut and the second nut.

[0009] According to some embodiments of the present invention, a bushing is threadedly connected to the axle, and the bushing abuts against the fixing plate to prevent the axle from disengaging from the fixing plate.

[0010] According to some embodiments of the present invention, a rubber plate is connected to the end of the axle away from the roller, and the rubber plate abuts against the sound insulation plate.

[0011] According to some embodiments of the present invention, a pre-embedded steel plate is bolted to the foundation, and the steel column is welded to the pre-embedded steel plate.

[0012] According to some embodiments of the present invention, the sound insulation panel is coated with anti-rust paint.

[0013] According to some embodiments of the present invention, a sealing strip is sandwiched between the sound insulation plate and the sidewall of the groove.

[0014] A sound barrier component at an expansion joint according to an embodiment of the present invention has at least the following beneficial effects:

[0015] (1) The rubber sheet clamps the sound insulation plate with the side wall of the groove. When the two steel columns approach and move away from each other, the sound insulation plate slides between the wheel axle 310 and the side wall of the groove, effectively sealing the gap between the two steel columns.

[0016] (2) The rubber sheet and the sound insulation board are pressed together to prevent the sound insulation board from resonating with the noise;

[0017] (3) Anti-rust paint prevents the sound insulation board from rusting and corroding in the open environment.

[0018] The present invention also provides a method for treating a sound barrier component at an expansion joint, applicable to the aforementioned sound barrier component, comprising the following steps:

[0019] S1. Pour the foundation, and pour the embedded steel plate and embedded bolts into the foundation;

[0020] S2. Weld the anti-detachment plate inside the groove of the steel column, cut the fixing plate, rotate and install the two rollers to both sides of the fixing plate respectively, and fix the rubber plate on the wheel axle;

[0021] S3. Fix the steel columns on the foundation, embed the two rollers on the fixing plate into the corresponding grooves, cut the sound insulation board according to the spacing between adjacent steel columns, and insert the sound insulation board into the rubber plate and the side wall of the groove. Connect the sound insulation board to the fixing plate using the fixing bolts.

[0037] In the description of this invention, it should be noted that, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0038] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of the present invention, not all embodiments.

[0039] See Figures 1 to 4As shown, an embodiment of the present invention provides a sound barrier component at an expansion joint, comprising: two steel columns 100, a fixing plate 200, two rollers 300, a sound insulation plate 400, and fixing bolts 500. The steel columns 100 are I-beams and are vertically connected to the foundation 110. The two steel columns 100 are arranged in parallel, and a groove 120 is provided on one side of the two steel columns 100 facing each other. The groove 120 is located on the side of the two steel columns 100 that are close to each other. A wheel axle 310 is installed at the center of the rollers 300, and the rollers 300 can rotate around the wheel axle 310. A first bolt hole 210 is opened at the center of the fixing plate 200. Two bearing holes are provided on the fixed plate 200, symmetrically arranged with the first bolt hole 210 as the center. The axle 310 is rotatably mounted on the fixed plate 200, passing through the bearing holes. Two rollers 300 are symmetrically installed with the first bolt hole 210 as the center, and the two rollers 300 are respectively embedded in the corresponding grooves 120. An anti-detachment plate 130 is welded to the steel column 100 to prevent the rollers 300 from detaching from the grooves 120. The anti-detachment plate 130 is welded to the inner wall of the groove 120. When the rollers 300 move out of the grooves 120, they abut against the anti-detachment plate 130, so that the rollers 300 can only move up and down. During installation, the rollers 300 are placed into the grooves 120 through the opening at the top of the steel column 100. The sound insulation panel 400 is embedded in corresponding grooves 120 at both ends, and is sandwiched between the axle 310 and the sidewall of the groove 120. A fixing bolt 500 passes vertically through the fixing plate 200 and the sound insulation panel 400. The fixing bolt 500 provides auxiliary restraint for the sound insulation panel 400. As the two steel columns 100 move closer and further apart, the sound insulation panel 400 slides between the axle 310 and the sidewall of the groove 120, effectively sealing the gap between the two steel columns 100 and preventing noise from propagating through this gap. The length of the fixing plate 200 is greater than the maximum distance between the two steel columns 100.

[0040] It should be noted that a bearing can be installed in the bearing hole to reduce the friction between the axle 310 and the bearing hole.

[0041] See Figures 1 to 4 As shown, the sound insulation panel 400 has a second bolt hole 410 at its center, and the fixing bolt 500 passes through both the first bolt hole 210 and the second bolt hole 410. The fixing bolt 500 passes through the center of the fixing plate 200, ensuring that the sound insulation panel 400 remains centered on the two steel columns 100 as they move closer or further apart. Compared to directly welding the sound insulation panel 400 to a single steel column 100, this method effectively seals the gap between the two steel columns 100 even with greater expansion and contraction.

[0042] See Figures 1 to 4As shown, it can be understood that the dimensions of the sound insulation panel 400 are matched with the maximum and minimum distances between the two steel columns 100. When the two steel columns 100 are at their farthest distance, the sound insulation panel 400 can abut against the sidewalls of the two grooves 120, thus maintaining good sound insulation performance. When the two steel columns 100 are at their closest distance, a gap is left between the sound insulation panel 400 and the sidewalls of the two grooves 120 that are furthest apart, to prevent the sound insulation panel 400 from being squeezed and deformed.

[0043] See Figures 1 to 4 As shown, it can be understood that the fixing bolt 500 is threaded with a first nut 510 and a second nut 520, and the sound insulation plate 400 is sandwiched between the first nut 510 and the second nut 520. The first nut 510 and the second nut 520 serve to prevent the fixing bolt 500 from falling off and improve its service life.

[0044] See Figures 1 to 4 As shown, it can be understood that a bushing 311 is threaded onto the axle 310. After the axle 310 passes through the fixing plate 200, the bushing 311 is screwed in. The bushing 311 abuts against the fixing plate 200 to prevent the axle 310 from disengaging from the fixing plate 200. When the fixing bolt 500 is tightened, the fixing plate 200 abuts against the bushing 311, pushing the axle 310 to press against the sound insulation plate 400, so that the sound insulation plate 400 is tightly against the side wall of the groove 120, improving the sealing performance.

[0045] See Figures 1 to 4 As shown, it can be understood that a rubber plate 312 is connected to the end of the axle 310 away from the roller 300, and the rubber plate 312 abuts against the sound insulation panel 400. The rubber plate 312 is bolted to the axle 310. The rubber plate 312 increases the contact area with the sound insulation panel 400, preventing the axle 310 from damaging the sound insulation panel 400 and improving its service life. The rubber plate 312 also has a cushioning effect, preventing the sound insulation panel 400 from resonating with noise.

[0046] See Figures 1 to 4 As shown, it can be understood that a pre-embedded steel plate 111 is bolted to the foundation 110, and the steel column 100 is welded to the pre-embedded steel plate 111. The foundation 110 is made of cement, and the pre-embedded steel plate 111 is connected to the foundation 110 by expansion bolts, which effectively improves the installation speed, saves costs, and provides a horizontal surface for the installation of the steel column 100.

[0047] See Figures 1 to 4 As shown, it is understandable that the sound insulation panel 400 is coated with anti-rust paint. To save costs, the steel column 100, sound insulation panel 400, and fixing plate 200 are all made of ordinary steel plates, which are prone to rust and corrosion in open-air environments. The anti-rust paint coating on the surfaces of the steel column 100, sound insulation panel 400, and fixing plate 200 can extend their service life.

[0048] See Figures 1 to 4 As shown, a sealing strip is sandwiched between the sound insulation panel 400 and the side wall of the groove 120. The sealing strip is made of rubber material to further prevent noise from propagating through the gap between the sound insulation panel 400 and the side wall of the groove 120.

[0049] The present invention also provides a method for treating a sound barrier component at an expansion joint, applicable to the aforementioned sound barrier component, comprising the following steps:

[0050] S1. Cast the foundation 110, and cast the pre-embedded steel plate 111 and pre-embedded bolts into the foundation 110.

[0051] S2. Weld an anti-detachment plate 130 inside the groove 120 of the steel column 100, cut the fixing plate 200, and open the first bolt hole 210 in the center of the fixing plate 200. Insert two rollers into the bearing hole, connect the bushing 311 to the roller, and fix the rubber plate 312 to the axle 310.

[0052] S3. Vertically weld the steel column 100 to the pre-embedded steel plate 111. Insert the two rollers 300 on the fixing plate 200 into the grooves 120 from the upper ends of the two steel columns 100 respectively. Cut the sound insulation plate 400 according to the spacing between adjacent steel columns 100. Insert the sound insulation plate 400 through the top of the steel column 100 between adjacent steel columns 100 and make the sound insulation plate 400 between the rubber plate 312 and the side wall of the groove 120. After the fixing bolt 500 passes through the first bolt hole 210, install the first nut 510. Then, the fixing bolt 500 passes through the second bolt hole 410, install and tighten the second nut 520.

[0053] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
