Description

Technical Field

[0001] This invention relates to the field of composite building technology, specifically to a composite building wall structure for preventing solid-borne noise waves. Background Technology

[0002] When constructing walls for composite buildings, appropriate sound insulation structures are typically incorporated to prevent solid-borne noise waves. A search revealed that Chinese patent CN219138041U discloses a composite building wall structure for preventing solid-borne noise waves, comprising a wall body and a shell. By adding a disassembly structure, the sound insulation panels can be easily disassembled, maintained, or replaced, thereby improving the efficiency of their use.

[0003] Chinese patent CN210342317U discloses a composite building wall structure for preventing solid-borne noise waves, belonging to the field of building walls. It includes keel, frame and panel. The keel is arranged vertically side by side, and a hollow sound-absorbing cylinder is set between two adjacent keels. The sound-absorbing cylinder is set in the gap between the keels. Noise enters the sound-absorbing cylinder through the through hole. The two ends of the sound-absorbing cylinder are closed by end plates to form a resonance cavity, so that the noise resonates and dissipates energy in the sound-absorbing cylinder, thereby improving the sound absorption effect.

[0004] Both of the above technical solutions can achieve the function of noise reduction. However, the first technical solution involves installing corresponding disassembly structures at both ends of the wall to achieve quick installation and disassembly of the sound insulation panels. In actual use, it is necessary to operate the disassembly structures at both ends separately. Installing disassembly structures at both ends not only occupies a lot of space, but also makes it inconvenient to build the wall. Furthermore, it is impossible to combine two adjacent sound insulation panels. Although the second technical solution installs the sound-absorbing cylinder between the keel, reducing the thickness and space occupied, it is inconvenient to disassemble and replace it. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a composite building wall structure for preventing solid-borne noise waves. It solves the problems mentioned in the background art, such as the inconvenience of quick assembly and disassembly of the sound insulation structure of existing composite building wall structures, and the large space required for the disassembly mechanism of the sound insulation panel of existing composite building wall structures, which also makes wall construction inconvenient.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a composite building wall structure for preventing solid-borne noise waves, comprising a wall body, with sound insulation panels on both sides of the outer surface of the wall body, and multiple L-shaped clamps symmetrically fixedly connected to the outer surface of the sound insulation panels and the side closest to the wall body, with multiple grooves that cooperate with the L-shaped clamps on both sides of the outer surface of the wall body, and a storage groove on one side of the inner wall of the grooves, and a long groove at the center of both sides of the outer surface of the wall body, with a clamping mechanism that cooperates with the L-shaped clamps directly installed through the long groove and the storage groove, and a driving mechanism that cooperates with the clamping mechanism installed inside the long groove, and a connecting mechanism installed on both sides of the outer surface of the sound insulation panels.

[0007] The clamping mechanism includes a rotating rod that passes through the long groove and the storage groove and is rotatably connected to the wall body. The outer surface of the rotating rod located inside the storage groove is threaded with a pressing block that is slidably connected to the inner wall of the storage groove. One end of the pressing block and one end of the L-shaped clamping rod are both provided with a first inclined surface. The end of the rotating rod located inside the long groove is fixedly connected to a first bevel gear. The inner wall of the groove is fixedly connected to a first spring that contacts the L-shaped clamping rod. The clamping mechanism, in conjunction with the L-shaped clamping rod, can realize the installation and removal of the sound insulation panel.

[0008] The driving mechanism includes a rotating shaft rotatably connected inside the long slot. Multiple second bevel gears are fixedly sleeved on the outer surface of the rotating shaft. The second bevel gears mesh with adjacent first bevel gears. Rotation of the rotating shaft can simultaneously drive multiple second bevel gears to rotate, thereby simultaneously driving the clamping mechanisms on both sides to operate.

[0009] Preferably, the driving mechanism further includes a baffle fixedly installed inside the long groove. The outer surface of the baffle has a circular groove, and a circular rod is rotatably connected through the inside of the circular groove. One end of the circular rod is fixedly connected to a third bevel gear that meshes with the second bevel gear, and the other end of the circular rod is fixedly connected to a knob. Rotating the knob drives the third bevel gear to rotate, thereby driving the second bevel gear and the rotating shaft to rotate.

[0010] Preferably, the connecting mechanism includes a rectangular groove formed on one side of the sound insulation panel, a rectangular plate slidably connected inside the rectangular groove, a plurality of inserts being fixedly connected sequentially on one side of the outer surface of the rectangular plate, and a plurality of slots that cooperate with the inserts being formed on one side of the outer surface of the sound insulation panel. The cooperation between the inserts and the slots can realize the connection between two adjacent sound insulation panels, which is convenient for limiting and locking.

[0011] Preferably, a circular hole is formed on the outer surface of the sound insulation board at a position corresponding to the circular groove. A limiting groove is formed on one side of the inner wall of the circular hole. A push block is slidably connected to the inner wall of the limiting groove. A push rod is fixedly connected to one end of the push block. The push rod passes through the sound insulation board and is fixedly connected to one side of the rectangular plate. Pressing the push block drives the insert block to move through the push rod.

[0012] Preferably, a second spring is fixedly connected between the push block and the inner wall of the limiting groove to facilitate the reset of the push block, and a second inclined surface is provided on the outer surface of one end of the push block to facilitate the squeezing of the push block.

[0013] Preferably, the internal thread of the circular hole is connected to a soundproof cover to facilitate the pressing of the push block, and a slot is provided on one side of the outer surface of the soundproof cover to facilitate the rotation of the soundproof cover.

[0014] This invention provides a composite building wall structure for preventing solid-borne noise waves. It possesses the following features:

[0015] Beneficial effects:

[0016] 1. This composite building wall structure for preventing solid-borne noise waves, through the setting of a clamping mechanism and a driving mechanism, can drive multiple clamping mechanisms to operate simultaneously when the driving mechanism is running, thereby realizing the installation and disassembly of the sound insulation panel without having to operate each clamping mechanism separately, thus improving work efficiency. It solves the problem that the installation and disassembly of existing composite building wall sound insulation panels requires separate operations on the top and bottom, increasing the workload and reducing work efficiency.

[0017] 2. This composite building wall structure for preventing solid-borne noise waves, through the setting of a drive mechanism, a circular groove and a circular hole, allows the drive mechanism to be installed between the sound insulation board and the wall body without occupying external space. This solves the problem that existing composite building wall structures with fixed sound insulation boards are installed on the outside of the wall, occupying a large space and affecting the construction of the wall.

[0018] 3. This composite building wall structure for preventing solid-borne noise waves, through the set connecting mechanism and soundproof cover, when the soundproof cover is screwed in, can drive the insert in the connecting mechanism into the slot in the adjacent soundproof board, thereby realizing the connection between two adjacent soundproof boards, which is convenient for combination and makes it more solid. This solves the problem that the soundproof boards of existing composite building walls are all separate and inconvenient to combine. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1:

[0032] like Figures 1-4As shown, a composite building wall structure for preventing solid-borne noise waves includes a wall body 1. Sound insulation panels 2 are provided on both sides of the outer surface of the wall body 1. Multiple L-shaped clamps 3 are symmetrically fixed to the outer surface of the sound insulation panels 2, particularly on the side closest to the wall body 1. Multiple grooves 4 that mate with the L-shaped clamps 3 are formed on both sides of the outer surface of the wall body 1. A storage groove 5 is formed on one side of the inner wall of each groove 4. Long grooves 6 are formed at the center of both sides of the outer surface of the wall body 1. A clamping mechanism 7 that mates with the L-shaped clamps 3 is directly installed through the long grooves 6 and the storage grooves 5. The clamping mechanism 7 includes a rotating rod 71 that passes through the long grooves 6 and the storage grooves 5 and is connected to the wall body. 1. Rotary connection: The outer surface of one end of the rotating rod 71 located inside the storage groove 5 is threaded with a pressing block 72 that is slidably connected to the inner wall of the storage groove 5. One end of the pressing block 72 and one end of the L-shaped clamp 3 are both provided with a first inclined surface. One end of the rotating rod 71 located inside the long groove 6 is fixedly connected with a first bevel gear 73. The inner wall of the groove 4 is fixedly connected with a first spring 74 that contacts the L-shaped clamp 3. The rotation of the first bevel gear 73 drives the rotating rod 71 to rotate, which in turn drives the pressing block 72 to move through the thread. Under the action of the first inclined surface, one end of the L-shaped clamp 3 is pressed, causing the L-shaped clamp 3 to move, thereby fixing the sound insulation panel 2. Conversely, the sound insulation panel 2 can be disassembled.

[0033] Example 2:

[0034] like Figures 1-8 As shown, a drive mechanism 8 that cooperates with the clamping mechanism 7 is installed inside the long groove 6. The drive mechanism 8 includes a rotating shaft 81 rotatably connected inside the long groove 6. Multiple second bevel gears 82 are fixedly sleeved on the outer surface of the rotating shaft 81. The second bevel gears 82 mesh with adjacent first bevel gears 73. The rotation of the rotating shaft 81 drives the multiple second bevel gears 82 to rotate simultaneously, thereby simultaneously driving the multiple clamping mechanisms 7 on both sides to operate simultaneously without separate operation, thus improving work efficiency and solving the problem that the installation and disassembly of existing composite building wall sound insulation panels require separate operations on the top and bottom, increasing the workload and reducing work efficiency.

[0035] The drive mechanism 8 also includes a baffle 83 fixedly installed inside the long slot 6. The outer surface of the baffle 83 has a circular slot 84. A circular rod 85 is rotatably connected through the inside of the circular slot 84. One end of the circular rod 85 is fixedly connected to a third bevel gear 86 that meshes with the second bevel gear 82. The other end of the circular rod 85 is fixedly connected to a knob 87. Rotating the knob 87 drives the circular rod 85 and the third bevel gear 86 to rotate, thereby driving the corresponding second bevel gear 82 to rotate, and then driving the rotating shaft 81 to rotate. The circular slot 84 can store the knob 87, so as not to occupy extra space. This solves the problem that the existing composite building wall-fixed sound insulation board structure is installed on the outside of the wall, occupying a lot of space and affecting the construction of the wall.

[0036] Example 3:

[0037] like Figures 1-10 As shown, the sound insulation panel 2 has connecting mechanisms 9 installed on both sides of its outer surface. The connecting mechanism 9 includes a rectangular groove 91 on one side of the sound insulation panel 2. A rectangular plate 92 is slidably connected inside the rectangular groove 91. A plurality of inserts 93 are fixedly connected to one side of the outer surface of the rectangular plate 92. A plurality of slots 94 that cooperate with the inserts 93 are provided on one side of the outer surface of the sound insulation panel 2. The inserts 93 are inserted into the slots 94 in adjacent sound insulation panels 2, which can realize the positioning and splicing between two adjacent sound insulation panels 2, thereby making them more solid. This solves the problem that the sound insulation panels of existing composite building walls are all separate and inconvenient to combine.

[0038] A circular hole 95 is provided on the outer surface of the sound insulation plate 2 at a position corresponding to the circular groove 84. A limiting groove 96 is provided on one side of the inner wall of the circular hole 95. A push block 97 is slidably connected to the inner wall of the limiting groove 96. A push rod 98 is fixedly connected to one end of the push block 97. The push rod 98 passes through the sound insulation plate 2 and is fixedly connected to one side of the rectangular plate 92. The movement of the push block 97 drives the push rod 98 to move, thereby driving the rectangular plate 92 and the insert block 93 to move.

[0039] A second spring 99 is fixedly connected between the push block 97 and the inner wall of the limiting groove 96. A second inclined surface is provided on the outer surface of one end of the push block 97. The second spring 99 facilitates the reset of the push block 97, and the second inclined surface facilitates the squeezing of the push block 97.

[0040] The soundproof cover 10 is connected to the internal thread of the circular hole 95. A slot 11 is provided on one side of the outer surface of the soundproof cover 10. The soundproof cover 10 facilitates the squeezing of the push block 97 and also has the effect of sound insulation.

[0041] Working principle: When installing the sound insulation panel 2 on the wall of a composite building, simply insert the L-shaped clamping rod 3 on the sound insulation panel 2 into the groove 4, and then rotate the knob 87. The rotation of the knob 87 drives the round rod 85 and the third bevel gear 86 to rotate, thereby driving the corresponding second bevel gear 82 to rotate, which in turn drives the rotating shaft 81 to rotate. The rotation of the rotating shaft 81 drives multiple second bevel gears 82 to rotate simultaneously, thereby simultaneously driving the first bevel gears 73 in multiple clamping mechanisms 7 on both sides to rotate simultaneously. The rotation of the first bevel gears 73 drives the rotating rod 71 to rotate, which drives the pressing block 72 to move through the thread. Under the action of the first inclined surface, one end of the L-shaped clamping rod 3 is pressed, causing the L-shaped clamping rod 3 to move, thereby fixing the sound insulation panel 2. This solves the problem that the installation and disassembly of sound insulation panels on the walls of existing composite buildings require separate handling. Operating from the top and bottom increases workload and reduces efficiency. The knob 87 can be stored in the circular groove 84, eliminating the need for extra space. This solves the problem of existing composite building wall-fixed soundproofing panels being installed on the outside of the wall, occupying a large space and affecting wall construction. The soundproofing cover 10 is then screwed into the circular hole 95 via threads. The soundproofing cover 10 then presses against the push block 97. The movement of the push block 97 moves the push rod 98, which in turn moves the rectangular plate 92 and the insert block 93. The insert block 93 inserts into the slot 94 in the adjacent soundproofing panel 2, enabling positioning and splicing between adjacent soundproofing panels 2, making them more secure. This solves the problem that existing composite building wall soundproofing panels are all separate and inconvenient to combine.

[0042] When it is necessary to remove the sound insulation panel 2, simply turn the knob 87 in the opposite direction.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
