Description

Technical Field

[0001] This utility model relates to the field of sound barrier equipment, specifically an externally mounted combined steel frame sound barrier. Background Technology

[0002] The most common process in the field of steel structure sound barriers is the insert plate type, which involves inserting unit plates into the H-shaped steel structure. In the current sound barrier implementation process, due to the difficulty in controlling the precision of processing and installation, there are often cases where the elastic rubber strips between the main steel structure and the sound barrier unit plates are missing or not sealed properly. Gaps appear between the unit plates and the steel structure, which will cause noise to escape and affect the noise reduction effect of the sound barrier.

[0003] According to the patent document CN217203684U, an externally applied combined sound barrier system includes an H-shaped steel frame, a support system, sound barrier unit panels, a support keel, and a cavity-type sound insulation panel. Multiple H-shaped steel frames are vertically embedded into the bottom foundation at intervals. Adjacent H-shaped steel frames are fixedly connected by the support system to form a stable spatial structure system. The sound barrier unit panels are located inside the inner flange of the H-shaped steel frames. In use, the cavity-type sound insulation panel encloses the structure within the system, improving the continuity of the external landscape and contributing to a good aesthetic effect. However, while this solution encloses the sound insulation panel, it makes it difficult to fine-tune the installation position of the sound insulation panel and noise reduction panel during initial installation, resulting in inconvenience. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an externally applied combined steel frame sound barrier to solve the problems mentioned in the background. This utility model has a novel structure. In use, the sound insulation panel moves inside the cavity via a movable frame. This movement allows for fine adjustments to the position of the sound insulation panel, facilitating rapid installation in the early stages. In addition, the sound-absorbing panel inside the cavity weakens the noise inside the cavity, preventing noise from being transmitted outward through the cavity.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an externally applied combined steel frame sound barrier, comprising a steel structure, the interior of which has a cavity, a movable frame movably installed inside the cavity, a support plate welded between the steel structures, a threaded pipe fixed on the support plate, a threaded rod rotatably installed inside the threaded pipe, a limit seat fixed at one end of the threaded rod, a fixing component fixedly installed on one side of the steel structure, and a sound insulation plate movably installed inside the movable frame.

[0006] Furthermore, a sound-absorbing plate is fixed to the inner wall of the cavity, and a fixing block is welded and fixed to the bottom of the steel structure, with fixing holes opened on the fixing block.

[0007] Furthermore, the fixing assembly includes a fixing plate, and a support rod is movably mounted between the fixing plates. The support rod is mounted on the fixing plate via a torsion spring shaft.

[0008] Furthermore, one end of the support rod has an opening, and a rotating shaft is movably installed inside the opening. A connecting plate is fixed on the rotating shaft, and a noise reduction plate is fixedly installed on the connecting plate.

[0009] Furthermore, a connecting block is welded to the side of the support rod, and a threaded column is movably mounted on the connecting block, with a fixing groove on the threaded column.

[0010] Furthermore, the connecting block is installed inside the fixed groove via a rotating column, and an adjusting screw is rotatably installed between the threaded columns.

[0011] Furthermore, a sliding groove is formed on the inner wall of the cavity, and a slider is movably installed inside the sliding groove, with one end of the slider fixed to the movable frame.

[0012] Furthermore, a support mechanism is fixed inside the groove, and one end of the support mechanism is fixed to the slider.

[0013] The beneficial effects of this utility model are:

[0014] 1. This externally applied combined steel frame sound barrier allows the sound insulation panels to move within the cavity via a movable frame during use. This movement allows for fine adjustments to the position of the sound insulation panels, facilitating rapid installation in the early stages. Additionally, the sound-absorbing panels inside the cavity attenuate noise within the cavity, preventing noise from being transmitted outward through the cavity.

[0015] 2. This type of externally applied combined steel frame sound barrier features an adjusting screw tube that rotates on a threaded column. The threaded column retracts inside the adjusting screw tube, and the support rod tilts inward under the influence of the threaded column. This tilting controls the installation distance between the noise reduction plate and the steel structure. The support rod provides multi-point support for the noise reduction plate, facilitating the subsequent installation and fixing of the equipment. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: an externally applied combined steel frame sound barrier, including a steel structure 1, a cavity 2 inside the steel structure 1, a movable frame 3 movably installed inside the cavity 2, a support plate 4 welded between the steel structures 1, a threaded tube 7 fixed on the support plate 4, a threaded rod 8 rotatably installed inside the threaded tube 7, a limit seat 9 fixed at one end of the threaded rod 8, a fixing component 5 fixedly installed on one side of the steel structure 1, a sound insulation plate 23 movably installed inside the movable frame 3, a sound-absorbing plate 19 fixed on the inner wall of the cavity 2, a fixing block 6 welded and fixed to the bottom of the steel structure 1, the fixing block 6 having a fixing hole, the threaded rod 8 rotating in the threaded tube 7 to adjust the position of the limit seat 9, the limit seat 9 can control the displacement length of the movable frame 3, thereby realizing the limiting and fixing of the movable frame 3.

[0024] In this embodiment, the fixing component 5 includes a fixing plate 10, and a support rod 11 is movably installed between the fixing plates 10. The support rod 11 is mounted on the fixing plate 10 via a torsion spring shaft. One end of the support rod 11 has an opening 12, and a rotating shaft 13 is movably installed inside the opening 12. A connecting plate 14 is fixed on the rotating shaft 13, and a noise reduction plate 24 is fixedly installed on the connecting plate 14. A connecting block 15 is welded to the side of the support rod 11, and a threaded post 16 is movably installed on the connecting block 15. A fixing groove 17 is opened on the threaded post 16. The connecting plate 14 is inclined inside the opening 12 via the rotating shaft 13, and is inclined to connect and fix with the noise reduction plate 24.

[0025] In this embodiment, the connecting block 15 is installed inside the fixed groove 17 via a rotating column. An adjusting screw tube 18 is rotatably installed between the threaded columns 16. A sliding groove 20 is opened on the inner wall of the cavity 2. A slider 21 is movably installed inside the sliding groove 20. One end of the slider 21 is fixed to the movable frame 3. A support mechanism 22 is fixed inside the sliding groove 20. One end of the support mechanism 22 is fixed to the slider 21. The support mechanism 22 is a support spring. The support spring provides support force after the movable frame 3 moves. The support mechanism 22 provides support and limit for the subsequent movement of the movable frame 3.

[0026] In use, the steel structure 1 is fixed in place by the fixing block 6. The limiting seat 9 and the threaded rod 8 are rotated, and the threaded rod 8 protrudes from the threaded tube 7. After protrusion, the position of the limiting seat 9 is adjusted. After the limiting seat 9 is adjusted, the distance the movable frame 3 can move is limited. After the limiting seat 9 is adjusted, the installation and adjustment of the fixing component 5 are realized. The adjusting screw tube 18 is rotated on the threaded column 16. At the same time, the threaded column 16 moves inward and retracts into the interior of the adjusting screw tube 18. The threaded column 16 drives the support rod 11 to tilt on the fixing plate 10 through the connecting block 15. After the support rod 11 tilts inward, the position of the connecting plate 14 is adjusted. The connecting plate 14 rotates through the rotating shaft 13. The noise reduction plate 24 is in contact with the connecting plate 14 and is fixed to the connecting plate 14 with bolts. After the noise reduction plate 24 is fixed, the threaded column 16 is moved up and down by adjusting the screw tube 18. The up and down movement of the threaded column 16 is adjusted by the support rod 11 to adjust the position of the noise reduction plate 24 for easy installation. Later, the sound insulation plate 23 is installed inside the movable frame 3 between the steel structures 1. The sound insulation plate 23 pushes the movable frame 3 to move towards the limiting seat 9. After the movable frame 3 contacts the limiting seat 9, it stops moving. Then, the other side of the sound insulation plate 23 is installed inside the movable frame 3 at another position. Under the push generated by the support mechanism 22, the sound insulation plate 23 is installed between the movable frames 3 for limiting and fixing.
