Description

Technical Field

[0001] This utility model relates to the field of noise reduction technology, specifically to a detachable noise insulation screen. Background Technology

[0002] In scenarios such as building rooftops, elevated platforms, and bridgeheads, there is noise from large electromechanical equipment, such as air conditioning units and cooling towers, as well as traffic noise. Although sound barriers are widely used as a mature sound barrier device, the traditional rigid connection installation method has revealed significant technical defects in long-term outdoor applications.

[0003] Specifically, existing technologies mostly employ rigid connection schemes with direct bolt fastening. However, these schemes have several drawbacks under extreme weather conditions (such as strong typhoons and torrential rains): First, rigid connections create a stress-locked structure between the sound barrier and the building structure. When bolts loosen, connectors fatigue and fracture, or even the entire sound barrier detaches or the structure breaks, requiring repeated disassembly and maintenance, irreversible damage to the building structure can occur. Specifically, the concrete around the mounting holes is prone to cracking and spalling, threatening the building's structural safety. For older buildings or lightweight roof structures, the impact load during bolt removal can trigger secondary disasters such as leaks and structural deformation. Furthermore, in bridge approach road scenarios, when rigidly connected sound barriers need replacement due to accidental impacts, repeated drilling operations are sometimes required, which also damages the road concrete and increases maintenance costs.

[0022] A detachable noise barrier, such as Figures 1-6As shown, the system includes a soundproof barrier body 4, a soundproof barrier mounting base, and a soundproof barrier connecting seat. The soundproof barrier body 4 is connected to the soundproof barrier connecting seat. The soundproof barrier connecting seat and the soundproof barrier mounting base are detachably connected. The soundproof barrier mounting base is rigidly connected to the building structure. When the soundproof barrier needs to be replaced, it is only necessary to detach the soundproof barrier body from the soundproof barrier connecting seat or detach the soundproof barrier connecting seat from the soundproof barrier mounting base. The advantage of this design is that when a damaged soundproof barrier body 4 needs to be replaced, there is no need to disassemble the soundproof barrier mounting base from the building structure, thus avoiding damage such as cracking of the mounting hole area on the building structure due to repeated disassembly and assembly, effectively protecting the building structure and ensuring the connection stability of the replaced soundproof barrier body 4.

[0023] Optionally, in this embodiment, such as Figures 2-3 As shown, the soundproof barrier mounting base includes a horizontal base plate 1, and a vertical base plate 9 is vertically arranged in the middle of the lower side of the horizontal base plate 1; a plurality of first fixing holes 11 are arranged in the left side of the horizontal base plate 1 along the vertical direction, and in this embodiment, the first fixing holes 11 are preferably countersunk holes; a plurality of second fixing holes 15 are arranged in the upper side of the vertical base plate 9 along the horizontal direction; a first vertical limiting plate 12 and a second vertical limiting plate 13 are arranged in the lower side of the right side of the horizontal base plate 1 along the vertical direction. In this embodiment, as... Figure 2 As shown, a reinforcing plate 14 is provided between the first vertical limiting plate 12 and the second vertical limiting plate 13, thereby forming a cuboid structure from the horizontal base plate, the first vertical limiting plate, the second vertical limiting plate and the reinforcing plate. This design can improve the stability and support of the first vertical limiting plate 12 and the second vertical limiting plate 13 during installation.

[0024] Optional, such as Figures 4-5 As shown, the soundproof barrier connector includes a horizontal connecting plate 2, a vertical connecting plate 6 is vertically connected to the lower side of one end of the horizontal connecting plate 2, and a lower connecting plate 17 is horizontally connected to the lower end of the vertical connecting plate 6; the vertical connecting plate 6 is horizontally provided with a plurality of first connecting holes 19 (threaded holes); the lower connecting plate 17 is vertically provided with a plurality of second connecting holes 18 (threaded holes); the second connecting holes 18 are preferably located at the lower front side of the horizontal connecting plate 2 to improve assembly stability; The function of the above structure is as follows: Figure 1As shown, a first tightening screw 5 is provided in the first connecting hole 19; a second tightening screw 7 is provided in the second connecting hole. In use, if a sound barrier is installed on a building rooftop, high platform, or other area, a rectangular mounting platform 10 (such as a concrete or brick structure) is first constructed on the horizontal building surface. If it is a bridgehead, the platform is constructed along the outer edge of the road surface at the bridgehead. The rectangular mounting platform 10 and the outer edge of the road surface are primarily for obtaining a right-angle mounting surface. Then, the sound barrier mounting base is first installed to the aforementioned building structure. For example, when installing on the rectangular mounting platform 10, several fixing holes are drilled on the top and side surfaces of the rectangular mounting platform 10. Then, first expansion bolts 11 and second expansion bolts 8 are used to tighten and fix the sound barrier mounting base to the rectangular mounting platform 10 through several first fixing holes 11 and several second fixing holes 15, respectively. The sound barrier mounting base is then rigidly connected to the rectangular mounting platform 10. Finally, the sound barrier connecting seat is installed onto the sound barrier mounting base. The installation operation is as follows: like Figure 1 As shown, the first tightening screw 5 is inserted into the first connecting hole 19, and the second tightening screw 7 is inserted into the second connecting hole 18. The first tightening screw 5 is pre-tightened, causing the soundproof barrier connecting seat to shift rearward. At this time, the side wall of the second tightening screw 7 abuts against the front side of the first vertical limiting plate 12 of the soundproof barrier mounting base. Then, the second tightening screw 7 is pre-tightened, causing the soundproof barrier connecting seat to press firmly against the horizontal base plate 1. Then, all the first tightening screws 5 and all the second tightening screws 7 are fully tightened, thus securing the soundproof barrier connecting seat onto the soundproof barrier mounting base. In some embodiments, the soundproof barrier body 4 can directly use an existing soundproof barrier body. In this embodiment, the following soundproof barrier body structure is preferred: like Figure 6 As shown, the lower part of the soundproof barrier 4 is provided with a barrier connecting seat 3. In some embodiments, such as... Figure 4 As shown, the screen connecting base 3 and the horizontal connecting plate 2 are detachably connected by bolts 16. In some embodiments, the screen connecting base 3 and the horizontal connecting plate 2 can also be directly welded together.

[0025] Optional, such as Figure 6 As shown, the soundproof barrier body 4 includes a front panel 20 and a back panel. The front panel 20 has several sound-absorbing through holes 23, and a cavity is formed between the front panel 20 and the back panel. In some examples, the cavity is filled with sound-absorbing material. Considering the outdoor environment, sound-absorbing materials such as glass wool and melamine foam, which meet the requirements of outdoor soundproof barriers in terms of weather resistance, water resistance, and structural stability, are preferred.

[0026] Optional, such as Figure 6As shown, the sound-absorbing material includes a first layer of sound-absorbing material, which may be made of melamine foam. The first layer has several protrusions on its front side, arranged alternately. In this embodiment, the protrusions are frustums, and the sound-absorbing through-holes 23 face the inclined surface of the frustum. Simultaneously, sound-transmitting through-holes 21 are horizontally arranged in the area between the protrusions. The function of this structure is to facilitate better transmission of external noise into the cavity between the front panel 20 and the back panel, and the arrangement of the sound-absorbing through-holes 23 facing the inclined surface of the frustum and the sound-transmitting through-holes 21 facilitate sound absorption and reduce sound wave reflection. In this embodiment, a second layer of sound-absorbing material is also included. The second layer of sound-absorbing material can be glass wool or slag wool, etc. It consists of several plate-shaped sound-absorbing materials stacked on top of each other and disposed on the back side of the first layer of sound-absorbing material. That is, it can be several plate-shaped glass wool stacked on top of each other or a mixture of several plate-shaped glass wool and several plate-shaped slag wool stacked on top of each other. The structure of multiple plate-shaped sound-absorbing materials stacked on top of each other can further improve the noise reduction of the noise transmitted from the self-transmission through hole 21. This structure not only improves the stability of the overall sound-absorbing material inside, but also helps to improve the noise reduction effect.
