Description

Technical Field

[0001] This invention relates to the field of spliced ​​soundproof wall technology, specifically a prefabricated spliced ​​modular soundproof cover. Background Technology

[0002] Noise pollution has become a significant issue affecting environmental quality, human health, and production efficiency in various fields such as industrial production, construction, transportation, and machinery operation. To reduce noise transmission, soundproof walls are widely used as an efficient noise reduction method. Their core function is to wrap and isolate the noise source through a combination of sealing and sound insulation materials, thereby reducing the intensity of noise radiation outward. However, existing soundproof wall technology suffers from poor structural flexibility and insufficient adaptability. Traditional soundproof walls mostly adopt an integral welded structure or a fixed-size splicing design, which cannot flexibly adjust the overall size and shape according to the size, shape, and installation space layout of the noise source. The overall construction splicing and disassembly efficiency is low, relying heavily on a large number of bolts for fastening and welding for fixing. Maintenance and replacement are inconvenient. When the soundproofing panels age, are damaged, or need to be replaced with panels of different soundproofing levels, the operation is complicated, the maintenance cycle is long, and it affects the normal production or use process. Summary of the Invention

[0006] Preferably, a plurality of the first frames are arranged in parallel relative to each other, and each of the opposite sidewalls near the rear end is provided with a plate groove, and a plurality of the second frames are provided with a plate groove on the opposite sidewalls that fits with the first frames.

[0007] Preferably, the sound insulation panel body is detachably embedded in the groove between the first frame and the second frame, and the sound insulation panel body is positioned and limited by the rectangular frame formed by splicing the first frame and the second frame.

[0008] Preferably, the docking structure includes a first mounting base, a pair of shaft seats, a first gripper, a second gripper, a pair of force-applying plates, several springs, a second mounting base, and a socket; the first mounting base is rectangular and can be detachably installed in a mounting groove; the pair of shaft seats are symmetrically arranged in the middle of the first mounting base; one end of the first gripper movably passes through the middle of the other end of the shaft seat on both sides, and the first gripper can be flipped on the first mounting base; the other end of the first gripper is V-shaped; a sleeve shaft passes through the middle of one end of the second gripper, and the second gripper is movably inserted into the first gripper and the shaft seat through both ends of the sleeve shaft; the other end of the second gripper is V-shaped; one end of the pair of force-applying plates is fixedly arranged in the middle of the first gripper and the second gripper, and the force-applying plates are horizontally opposite to the first mounting base; both ends of the several springs are fixedly connected between the first mounting base and the force-applying plates; the second mounting base is detachably embedded in the mounting groove; and one end of the socket is fixedly arranged in the middle of the second mounting base.

[0009] Preferably, the V-shaped ends of the second gripper and the first gripper are arranged symmetrically in opposite directions.

[0010] Preferably, the other end of the socket is cylindrical, and the other end of the socket is movably inserted between the first clamp and the second clamp.

[0011] Preferably, the first gripper is provided with a stop bar near the middle of both ends, and the stop bar corresponds to and fits into the sides of the second gripper.

[0012] Preferably, when the docking structure docks with the frame structure, the first mounting base and the second mounting base are respectively disposed in the mounting slots of the two opposing first frames or second frames.

[0013] Preferably, the frame structure can be spliced ​​horizontally or vertically through the docking structure, and the first frame structure can be spliced ​​relatively perpendicularly.

[0014] Preferably, the sleeve shaft of the second gripper is tightened and limited by the first bolt to prevent it from overturning under force.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: Regarding the fixed connection structure of existing soundproof walls, this invention prefabricates frame structures and soundproof panels of appropriate dimensions according to actual needs, and uses the same butt joint structure to achieve relative splicing and combination of the frame structures. The design of the butt joint structure enables relative plug-in connections, which also facilitates later maintenance and disassembly. Through the slots in the frame structure, soundproof panels with corresponding sound insulation coefficients can be installed according to actual needs to form a barrier for area sound insulation. The combination of the frame structure and the butt joint structure not only allows for straight splicing to form a soundproof wall, but also allows for relatively perpendicular splicing to form a cover-like structure, with seamless butt joints resulting in better sealing. In summary, this invention achieves the following effects: 1. The first frame, the second frame, and the main body of the sound insulation panel can be prefabricated according to the actual size and spatial layout of the scene, without the need for on-site cutting and processing, and can adapt to the personalized needs of different noise sources and installation spaces; a uniform docking structure is adopted, and the mounting grooves and threaded holes of all frame structures are uniform in size, ensuring that different modules can be universally spliced, reducing adaptation costs and improving assembly efficiency.

[0016] 2. The docking structure achieves rapid positioning through socket insertion and spring clamping. Only the first bolt needs to be tightened to complete the locking. Compared with traditional methods of fastening with a large number of bolts or welding, the splicing process is simplified and the installation efficiency is improved. The frame structure, the main sound insulation panel, and the docking structure are all detachable. When it is necessary to replace the aging sound insulation panel, adjust the layout, or relocate the equipment in the future, the components can be quickly disassembled without damaging the overall structure. Damaged individual components can be replaced individually to avoid resource waste. The modular components can be reassembled after disassembly to adapt to different scenarios and be reused repeatedly, reducing long-term use costs.

[0017] 3. The sound insulation boards with different sound insulation coefficients (such as rock wool boards, sound-absorbing cotton composite boards, etc.) can be embedded in the slots of the frame structure. The sound insulation requirements can be precisely matched according to the noise intensity (such as high-frequency noise from industrial equipment and low-frequency noise from traffic) to achieve noise reduction on demand. The docking structure tightly clamps the column socket with V-shaped claws. With the fit design after the frame is spliced, the splicing is seamless, which prevents noise from leaking from the splicing gap. The sealing effect is better than that of traditional spliced ​​sound insulation walls, and the sound insulation efficiency is improved.

[0018] 4. Not only can it support straight horizontal and vertical splicing to form soundproof walls, but it can also achieve relatively vertical splicing through docking structure to form a fully enclosed enclosure, breaking the limitation of traditional soundproof walls that can only be spliced ​​in a plane; the splicing angle can be flexibly adjusted according to the corners and three-dimensional layout of the site, and it can accurately cover the soundproof area whether it is a narrow space, an irregular site or a large equipment cluster. The application scenarios cover multiple fields such as industrial production, building construction, traffic roads, and noise reduction of mechanical equipment.

[0019] 5. The docking structure adopts a double fixation of spring elastic clamping and first bolt tightening sleeve shaft, combined with the stop bar limit of the first claw, which can effectively resist equipment vibration and external force collision, avoid loosening at the splice, and ensure the stability of long-term use; the first frame and the second frame are docked through the countersunk threaded hole of the second bolt, forming a rectangular frame structure with high strength, which can stably bear the weight of the sound insulation board, while resisting external impact and not easily deformed.

[0022] The following will refer to the appendices in the embodiments of the present invention. Figures 1-7 To provide further details.

[0023] This invention provides a technical solution: a prefabricated modular soundproof enclosure, comprising a frame structure 1, a soundproof panel body 2, and a docking structure 3. The soundproof panel body 2 is detachably installed inside the frame structure 1, and the docking structure 3 can dock the frame structure 1. The frame structure 1 can be detachably assembled to form a frame structure and supports the soundproof panel body 2. The docking structure 3 is detachably installed on the frame structure 1 for docking the frame structure 1.

[0024] The base material of the sound insulation board 2 is rock wool sound insulation board, sound-absorbing cotton composite board or polyurethane composite sound insulation board. All materials are environmentally friendly materials without formaldehyde or harmful additives, and have flame-retardant and moisture-proof properties, which are suitable for the safety requirements of different application scenarios.

[0025] When the main body 2 of the sound insulation board in this embodiment is a rock wool sound insulation board, the core material is made of high-purity basalt melt-drawn slender fiber rock wool with a uniform fiber pore structure. The two sides of the core material are laminated with fireproof non-woven fabric or galvanized steel plate. The density of this rock wool sound insulation board is 80-120kg / m³, the noise reduction coefficient NRC≥0.90, and the board thickness can be prefabricated to 50-100mm according to the sound insulation requirements. The whole board is made of A1 grade non-combustible material and can withstand long-term temperatures up to 500℃. The rock wool sound insulation board of this embodiment is suitable for high-frequency noise scenarios of industrial equipment, such as the sound insulation enclosure of high-noise industrial equipment such as machine tools, fans, and generators. After being embedded in the plate groove 7 of the frame structure 1, and with the seamless splicing design of the frame, the sound insulation volume is ≥50dB, which can effectively reduce the outward radiation of industrial high-frequency noise. Moreover, its high temperature resistance and impact resistance characteristics are suitable for the harsh working conditions of industrial production.

[0026] When the main body 2 of the sound insulation panel in this embodiment is a sound-absorbing cotton composite panel, the core material is centrifugal glass wool with a density of 48-64 kg / m³, and the outer side is a composite polyester fiber panel. The panel as a whole has good low-frequency sound energy absorption capacity and breathable moisture-wicking characteristics, and the panel thickness can be prefabricated to 30-80 mm. The sound-absorbing cotton composite panel of this embodiment is suitable for scenarios such as low-frequency noise from traffic roads and temporary construction site enclosures, such as the splicing of sound insulation walls on both sides of urban roads and highways, or temporary noise isolation enclosures at construction sites. It can accurately match the noise reduction needs of low-frequency traffic noise, and its lightweight characteristics facilitate the rapid splicing and overall disassembly of the frame structure 1.

[0027] When the main body 2 of the sound insulation panel in this embodiment is a polyurethane composite sound insulation panel, two molding methods are adopted: one is a rigid polyurethane foam core material composite aluminum foil layer, and the other is a mixture of polyurethane rubber particles, foamed rubber particles, and cork particles, which are then glued and pressed together. This panel has excellent compressive and bending resistance, and has both sound insulation and vibration reduction effects. It is also waterproof and moisture-proof, and the thickness can be customized from 3-20mm according to requirements. The overall panel is lightweight. The polyurethane composite sound insulation panel of this embodiment is suitable for the assembly of soundproof enclosures for small mechanical equipment, narrow spaces, or humid environments, such as the sound insulation enclosure of equipment like water pumps and small fans, or noise isolation in basements and open-air damp sites. Its vibration reduction characteristics can effectively reduce solid-borne sound caused by equipment vibration, and its lightweight characteristics are suitable for frame splicing operations in narrow spaces.

[0028] As a preferred embodiment, the frame structure 1 further comprises several first frames 11, several second frames 12, several first bolts 13, and several second bolts 14. Each of the first frames 11 is a square column, and mounting grooves 6 are correspondingly provided on the front and left side walls near both ends. Each of the first frames 11 has first countersunk threaded holes 4 communicating with the center of the mounting grooves 6 on its front and left side walls, and these first countersunk threaded holes 4 are perpendicularly connected. A pair of second countersunk threaded holes 5 are symmetrically provided on the left side wall near both the upper and lower ends. The first frames 11 are arranged parallel to each other, and plate grooves 7 are provided on opposite side walls near the rear ends. Each of the second frames 12 is a square column, and the width of the second frame 12 is the same as that of the first frame 11. The second frames 12 are detachably mounted between the ends of a pair of first frames 11, and the second frames 12 are connected by several... The second bolt 14 passes through the second countersunk threaded hole 5 and is connected to the first frame 11. Several second frames 12 have mounting grooves 6 and first countersunk threaded holes 4 that are the same as and correspond to the first frame 11 on their front sidewalls and upper walls near both ends. Several second frames 12 have plate grooves 7 that fit with the first frame 11 on their opposite sidewalls. Several first bolts 13 pass through the first countersunk threaded holes 4 and are connected to the mounting grooves 6. The second frames 12 are horizontally arranged between the two ends of the first frame 11 and are spliced ​​together by means of the second bolts 14 to form a frame. The sound insulation panel body 2 can be embedded in the plate groove 7 for limiting and setting, forming a single sound insulation structure. The sound insulation panel body 2 can be detachably embedded in the plate groove 7 between the first frame 11 and the second frame 12. The first frame 11 and the second frame 12 are spliced ​​together to form a rectangular frame to limit and set the sound insulation panel body 2.

[0029] More specifically, the frame structure 1 is the basic support component of the prefabricated modular soundproof enclosure. The core is composed of several first frames 11, several second frames 12, several first bolts 13 and several second bolts 14. The whole adopts a standardized and detachable design. The rectangular frame formed by splicing is fitted with the soundproof panel body 2 through the plate groove 7, which plays a role in stabilizing and limiting the soundproof panel, thus forming a single soundproof structure. The mounting groove 6 on the frame cooperates with the first countersunk threaded hole 4 to provide an installation base for the docking structure 3. The first bolt 13 can be moved through the first countersunk threaded hole 4 and communicate with the mounting groove 6 for subsequent locking and fixing of the docking structure 3.

[0030] As a preferred embodiment, the docking structure 3 further includes a first mounting base 31, a pair of shaft seats 32, a first gripper 33, a second gripper 34, a pair of force-applying plates 35, several springs 36, a second mounting base 37, and a socket 38. The first mounting base 31 is rectangular and can be detachably installed in the mounting groove 6. The pair of shaft seats 32 are symmetrically arranged in the middle of the first mounting base 31. One end of the first gripper 33 moves through the middle of the other end of the shaft seat 32 on both sides, and the first gripper 33 can be connected to the first mounting base 37. 1. The first gripper 33 is flipped upside down, with one end of the first gripper 33 being V-shaped. A sleeve shaft 8 passes through the middle of one end of the second gripper 34. The second gripper 34 is movably inserted into the first gripper 33 and the shaft seat 32 via both ends of the sleeve shaft 8. The other end of the second gripper 34 is also V-shaped. The V-shaped ends of the second gripper 34 and the first gripper 33 are arranged symmetrically in opposite directions. A pair of force-applying plates 35 are fixedly disposed at one end in the middle of the first gripper 33 and the second gripper 34, respectively. The force-applying plates 35 are horizontally opposite to the first mounting base 31. Several springs 36 are fixedly connected at both ends to... Between the first mounting base 31 and the force-applying plate 35, the second mounting base 37 is detachably embedded in the mounting groove 6. One end of the socket 38 is fixedly disposed in the middle of the second mounting base 37, and the other end of the socket 38 is cylindrical, and the other end of the socket 38 is movably inserted between the first clamp 33 and the second clamp 34. The first mounting base 31 and the second mounting base 37 are respectively embedded in the corresponding first frame 11 or second frame 12, thereby the socket 38 is inserted between the first clamp 33 and the second clamp 34, and the spring 36 acts as a spring. Force causes the first gripper 33 and the second gripper 34 to flip open on the bearing seat 32 and clamp the socket 38 to achieve plug-in connection. Finally, the first bolt 13 is used to tighten and limit the sleeve shaft 8 of the second gripper 34 to achieve locking and complete the connection. That is, the connection of the frame structure 1 is achieved through the connection structure 3. The first gripper 33 is provided with a stop bar 9 near the middle of both ends, and the stop bar 9 is correspondingly matched with the two sides of the second gripper 34 to block and limit the movement. The sleeve shaft 8 of the second gripper 34 is tightened and limited by the first bolt 13 to prevent it from flipping under force.

[0031] More specifically, the docking structure 3 enables precise multi-directional splicing of the frame structure 1. It employs a combination of plug-in clamping and bolt locking, featuring detachability, stable docking, and strong sealing. The first mounting base 31 and the second mounting base 37 are respectively embedded into the mounting grooves 6 of the first frame 11 and the second frame 12 to be docked. Pushing the first frame 11 and the second frame 12 causes the cylindrical socket 38 on the second mounting base 37 to insert between the first jaw 33 and the second jaw 34. The spring 36 applies elastic force through the force plate 35, driving the two jaws to rotate around the shaft seat 32. The V-shaped clamping opening tightly wraps around and holds the socket 38. The first countersunk threaded hole 4 on the first frame 11 and the second frame 12 is screwed into the first bolt 13. The first bolt 13 presses against the sleeve shaft 8 of the second clamp 34, restricting the first clamp 33 and the second clamp 34 from being rotated under force, achieving stable positioning after docking and completing the frame locking. The mounting groove 6 is provided on the adjacent side walls of the first frame 11 and the second frame 12, which can realize the horizontal splicing, vertical splicing and relatively vertical splicing of the frame structure 1, and adapt to various splicing forms such as straight walls and three-dimensional covers. All components are designed to be detachable, which is convenient for later disassembly and maintenance and frame reorganization, and adapts to the splicing and adjustment needs of different scenarios.

[0032] As a preferred option, furthermore, when the docking structure 3 docks with the frame structure 1, the first mounting base 31 and the second mounting base 37 are respectively set in the mounting slots 6 of the two opposing first frames 11 or second frames 12; the first frame 11 structure 1 can be spliced ​​horizontally or vertically through the docking structure 3, and the first frame 11 structure 1 can be spliced ​​relatively perpendicularly.

[0033] Working principle: First, connect the two ends of the second frame 12 to the two ends of the relatively parallel first frame 11. After the second bolt 14 passes through the second countersunk threaded hole 5 of the first frame 11, it is screwed into the two ends of the second frame 12 for fixed connection. When the rectangular frames are connected, the required sound insulation board body 2 is placed in the board groove 7 for positioning. Then, the first mounting base 31 and the second mounting base 37 in the docking structure 3 are respectively embedded into the mounting grooves 6 of the first frame 11 or the second frame 12 that are connected. Then, the two sets of frame structures 1 are fitted together, so that the corresponding socket 38 is inserted between the first clamp 33 and the second clamp 34. When the socket 38 is inserted, the first clamp 33 and the second clamp 34 are subjected to force and are flipped by the shaft seat 32 and the sleeve shaft 8 respectively. After flipping, the spring 36 between the force plate 35 and the first mounting base 31 helps to reset and maintain the clamping state. Thus, by fitting the frame structure 1 with the frame structure 1, and by passing the first bolt 13 through the first countersunk threaded hole 4, the first bolt 13 is forced to press against the sleeve shaft 8, thereby limiting the second gripper 34. As a result, the single first gripper 33 achieves locking due to its limited rotation angle. The frame structure 1 achieves horizontal splicing, vertical splicing, and relatively vertical splicing through the docking structure 3, which can form a soundproof wall. When disassembling, simply unlock the first bolt 13, and then pull it out to separate.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention, as long as they do not depart from the spirit and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
