Description

Technical Field

[0001] This utility model relates to the field of floor slab sound insulation and vibration reduction technology, and in particular to a building floor slab sound insulation and vibration reduction device. Background Technology

[0002] As an important horizontal load-bearing structure in a building, the floor slab plays a key role in separating the spaces between upper and lower floors. It not only bears its own load and various loads above it, but also transfers these loads to the vertical load-bearing components to ensure the stability of the overall building structure. At the same time, the floor slab also provides people with relatively independent living spaces to a certain extent, and has certain fireproof and waterproof functions, ensuring the safety of the living and use environment.

[0003] To further improve the quality of building space and reduce the adverse effects of sound transmission and vibration from floor slabs, building floor sound insulation and vibration damping devices have emerged. These devices are mainly installed in the floor slab structure and aim to effectively reduce the transmission of sound and vibration between upper and lower floors caused by human activities and equipment operation, thereby creating a quieter and more comfortable indoor environment.

[0004] Existing sound insulation and vibration reduction devices for building floors achieve sound insulation and vibration reduction by laying elastic materials between the floor base layer and the decorative surface layer. Rubber pads and foam boards are laid. These elastic materials absorb and buffer vibration energy through their own elastic deformation, thereby reducing the transmission of sound. However, during long-term use, the elastic materials are affected by the continuous pressure transmitted from the floor and changes in temperature and humidity, and their elasticity gradually decreases, resulting in a weakening of their buffering capacity and a significant reduction in the sound insulation and vibration reduction effect.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a building floor slab sound insulation and vibration reduction device. The floor slab 1 serves as the basic load-bearing structure, with a clamping plate 3 on its top. The clamping plate 3 provides protection and stability to the upper structure. Hollow columns 4 are fixedly connected to the left and right sides of the top of the floor slab 1, providing support and space for movable columns 6. Springs 1-5 are fixedly connected to the bottom inner sides of both hollow columns 4, initially buffering vibration energy. Movable columns 6 are fixedly connected to the top of both springs 1-5, extending and retracting with the springs 1-5 and transmitting vibration. Circular grooves 7 are provided at the bottom of both movable columns 6, providing space for columns 9. Springs 2-8 are fixedly connected to the top inner sides of both circular grooves 7, further buffering vibration. Columns 9 are fixedly connected to the other ends of both springs 2-8. The column 9 works with the spring 8 to buffer vibration. The top of each of the two movable columns 6 is fixedly connected to a pad 10, which evenly distributes the vibration. The top of each of the two pads 10 is fixedly connected to the same sound insulation plate 11, which is used to block the transmission of sound. The top of the sound insulation plate 11 is fixedly connected to the bottom of the clamping plate 3, which together with the clamping plate 3 ensures the quietness of the upper space. The top of the floor slab 1 is provided with a reinforcement mechanism 2, which is used to reinforce the hollow column 4 and enhance the structural stability of the device. The left and right sides of the interior of each of the two movable columns 6 are provided with limit grooves 13, which are used to limit the movement direction of the limit block 14. The left and right sides of the top of each of the two columns 9 are fixedly connected to limit blocks 14. The limit blocks 14 cooperate with the limit grooves 13 to ensure the stable movement of the columns 9. The two limit blocks 14 are slidably connected to the interior of the limit grooves 13 respectively.

[0033] Specifically, when external vibrations or noise occur, the vibration is first transmitted to floor slab 1. The clamping plate 3 at the top of floor slab 1 provides initial stabilization and protection, preventing direct damage to the sound insulation and vibration damping structure below from objects on the upper floors. The hollow columns 4, fixedly connected to the left and right sides of the top of floor slab 1, are important support and buffer structures. When vibration is transmitted, spring 5 first comes into play, using its own compression and rebound to initially buffer the vibration. The movable column 6, fixedly connected to its top, moves up and down within the hollow column 4 as spring 5 extends and retracts. When vibration passes through the spring... When vibration is transmitted from point 5 to the movable column 6, the column 9 is in the circular groove 7. The elasticity of the spring 8 further buffers the vibration, reducing the amplitude of the vibration transmitted upward. The pads 10 fixedly connected to the top of the two movable columns 6 evenly distribute the vibration. The sound insulation plate 11 fixedly connected to the top of the pads 10 can further absorb the energy generated by the vibration and effectively block the transmission of sound, providing a quiet environment with good vibration reduction for the upper space. It restricts the direction of movement of the column 9 in the movable column 6, ensuring that the column 9 remains stable when sliding up and down in the circular groove 7, and avoiding shaking or displacement.

[0034] Reference Figure 1 and Figure 5 The reinforcing mechanism 2 includes two rings 201, which are used to connect the floor slab 1 and provide an installation base for the subsequent structure. The bottoms of the two rings 201 are fixedly connected to the top left and right sides of the floor slab 1, respectively. Connecting blocks 1 202 are fixedly connected to the top left and right sides of the two rings 201. Connecting blocks 1 202 serve to transfer the support plate 203, realizing the movable connection between the structures. The tops of multiple connecting blocks 1 202 are rotatably connected to the support plate 203. The support plate 203 can be adjusted in angle according to actual installation requirements to provide support force. The other ends of multiple support plates 203 are rotatably connected to connecting blocks 204. Connecting blocks 204 stabilize the support plate 203 and the arc plate 205. The hollow column 4 is reinforced by a series of connecting blocks 204, with an arc-shaped plate 205 fixedly connected to the other side of each block 204. The arc-shaped plate 205 surrounds the hollow column 4. Fixing bolts 206 are rotatably connected to the front and rear sides of the outer walls of the arc-shaped plates 205. The fixing bolts 206 are used to tighten the arc-shaped plates 205 so that they fit tightly against the hollow column 4. One side of each arc-shaped plate 205 fits against the outer wall of the hollow column 4. One end of each fixing bolt 206 passes through the corresponding arc-shaped plate 205 and is rotatably connected to the outer wall of the hollow column 4. By tightening the fixing bolts 206, the arc-shaped plate 205 applies pressure to the hollow column 4, enhancing the stability of the hollow column 4 and thus improving the structural strength of the entire sound insulation and vibration reduction device.

[0035] Specifically, when the sound insulation and vibration damping device needs to be reinforced, the support plate 203 can adjust its angle according to the actual installation requirements. The other end of the multiple support plates 203 is rotatably connected to the connecting block 204. The connecting block 204 firmly connects the support plate 203 to the arc plate 205. The multiple arc plates 205 surround the outer wall of the hollow column 4. When the fixing bolt 206 is rotated, it will gradually tighten, causing the arc plate 205 to shrink inward, thereby closely fitting the outer wall of the hollow column 4 to reinforce it. The reinforcement mechanism 2 is tightly connected to the hollow column 4, so that the supporting force transmitted by the support plate 203 through the arc plate 205 can act on the hollow column 4, thereby enhancing the structural stability of the entire device.

[0036] Reference Figure 3 , Figure 4 and Figure 5 Multiple fixing bolts 206 have slidably connected washers 12 on their outer walls. The washers 12 increase the contact area between the fixing bolts 206 and the arc-shaped plate 205, dispersing the pressure generated during fixing. One side of each washer 12 is in contact with the outer wall of the corresponding arc-shaped plate 205. Sealing rings 15 are fixedly connected to the tops of both hollow columns 4. The sealing rings 15 seal the tops of the hollow columns 4 to prevent debris from entering. Sealing strips 16 are fixedly connected to the inner sides of both sealing rings 15. The sealing strips 16 enhance the sealing effect and reduce the possibility of dust and other contaminants entering the hollow columns 4. Multiple arc-shaped plates 206... One side of each plate 205 is fixedly connected to a fixing plate 17. The fixing plate 17 is used to enhance the structural strength of the arc plate 205. One side of each fixing plate 17 is fixedly connected to multiple rubber pads 18 at equal intervals. The rubber pads 18 can buffer the impact force when the arc plate 205 comes into contact with other structures, and at the same time increase the friction force. The two columns 9 are respectively slidably connected to the interior of the corresponding circular grooves 7. The columns 9 slide smoothly in the circular grooves 7, and work with the spring 8 to buffer the vibration. The size of the columns 9 and the circular grooves 7 are matched to ensure that the columns 9 slide stably in the circular grooves 7, and accurately transmit and disperse the vibration energy.

[0037] Specifically, this involves increasing the contact area between the fixing bolt 206 and the arc plate 205, dispersing the pressure generated when the fixing bolt 206 is tightened, preventing the arc plate 205 from being damaged due to excessive local pressure, sealing the top of the hollow column 4 to prevent dust and debris from entering the interior of the hollow column 4 and affecting the normal operation of the spring 5 and the moving column 6, using the fixing plate 17 to enhance the structural strength of the arc plate 205, and the rubber pad 18 to provide cushioning and anti-slip function, ensuring that the column 9 can slide smoothly up and down in the circular groove 7, and working with the spring 8 to achieve secondary cushioning against vibration.

[0038] Working principle: When external vibration or noise occurs, the vibration is first transmitted to floor slab 1. The clamping plate 3 at the top of floor slab 1 plays a preliminary role in stabilizing and protecting the structure, preventing objects on the upper level from directly damaging the sound insulation and vibration reduction structure below. The hollow columns 4 fixedly connected to the left and right sides at the top of floor slab 1 are important support and buffer structures. When vibration is transmitted, spring 5 first plays its role, and through its own compression and rebound, it initially buffers the vibration. The movable column 6 fixedly connected to its top moves up and down in the hollow column 4 as spring 5 extends and retracts. When the vibration is transmitted to the movable column 6 through spring 5, the column 9 in the circular groove 7 relies on the elasticity of spring 8 to further buffer the vibration and reduce the amplitude of the vibration transmitted upward. The pads 10 fixedly connected to the top of the two movable columns 6 evenly disperse the vibration. The sound insulation plate 11 fixedly connected to the top of the pads 10 can further absorb the energy generated by the vibration and effectively block the transmission of sound, providing a quiet environment with good vibration reduction for the upper space.

[0039] Furthermore, the connecting block 202, which is fixedly connected to the top left and right sides of the ring 201, serves as a transfer function. The support plate 203, which is rotatably connected to the connecting block 202, can move around the connection point. When it is necessary to reinforce the sound insulation and vibration reduction device, the support plate 203 can adjust its angle according to the actual installation requirements. The other end of the multiple support plates 203 is rotatably connected to the connecting block 204. The connecting block 204 firmly connects the support plate 203 to the arc plate 205. The multiple arc plates 205 surround the outer wall of the hollow column 4. When the fixing bolt 206 is rotated, it will gradually tighten, causing the arc plate 205 to shrink inward, thereby tightly fitting the outer wall of the hollow column 4 and reinforcing it.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
