Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial building, in particular to an industrial building shock-absorbing and noise-reducing floor and a mounting method thereof. BACKGROUND

[0002] The load-bearing base is a commonly used structural component in construction, which has the characteristics of high strength, good durability, convenient construction, etc., and is widely used in factory floor, floor, foundation and other scenes. The load-bearing base meets the requirements of industrial scenes in strength, durability and functionality through material optimization and structural design. The performance of the load-bearing base directly affects the safety and service life of the industrial building. In construction, appropriate material ratio and process should be selected according to the load type and environmental conditions, and quality control should be strengthened to ensure the long-term stable operation of the plate body.

[0003] At present, the ground structure in industrial buildings not only needs to bear static and dynamic loads of equipment, materials and personnel, but also faces the dual challenges of vibration and noise control. The traditional method generally uses large-thickness and integrally poured reinforced concrete slabs as load-bearing bases. Although this type of structure can meet the basic strength and durability requirements, its high stiffness and high density physical properties also have significant drawbacks. In workshops where large power equipment is installed, the low-frequency vibrations generated by the equipment operation can be efficiently transmitted to the entire building structure through the rigid concrete base. This structural vibration transmission not only may cause fatigue damage to the main structure of the building, but also may seriously interfere with the normal operation of other precision instruments and detection equipment in the factory area that are sensitive to vibration. SUMMARY

[0004] To solve the problems in the background art, the present application provides an industrial building shock-absorbing and noise-reducing floor and a mounting method thereof.

[0005] An industrial building shock-absorbing and noise-reducing floor, characterized in that: it comprises a load-bearing base a, which is the structural basis of the system and is prefabricated by pouring high-performance concrete, providing the main bearing strength and stiffness to ensure that the entire floor system can stably support the upper equipment and load and reliably transmit the static and dynamic loads of the equipment to the foundation.

[0006] The load-bearing base a is provided with a buffer layer b on the surface, which comprises a frame for connecting adjacent buffer layers b; the frame constitutes a rigid peripheral boundary, integrating the internal shock-absorbing and noise-reducing modules into a unified whole. The pre-tightening force provided by the mounting bolts ensures the firmness of the frame connection.

[0007] The frame is formed by two first lateral frames and two second lateral frames being clamped to each other by bayonet and fastened by mounting bolts, and is fixedly installed around the top edge of the load-bearing base layer a, thereby providing installation bases and lateral constraints for all internal components. The rigid connection ensures that the system will not loosen or deform when subjected to horizontal force or torsion, and ensures that the shock isolation module can work in coordination and that local loads can be effectively dispersed to the entire base layer.

[0008] The frame is formed by two first lateral frames and two second lateral frames being clamped to each other by bayonet and fastened by mounting bolts, and is fixedly installed around the top edge of the load-bearing base layer a, thereby providing installation bases and lateral constraints for all internal components. The rigid connection ensures that the system will not loosen or deform when subjected to horizontal force or torsion, and ensures that the shock isolation module can work in coordination and that local loads can be effectively dispersed to the entire base layer.

[0009] When the vibration is transmitted from the panel layer, the buffer block first compresses and shears, and the gap between the baffle plates provides the necessary deformation space for the buffer block. When the buffer block laterally deforms in vibration, it will squeeze the damping pad. The damping pad made of butyl rubber has a high loss factor, which can convert the squeezed kinetic energy into heat energy through internal molecular friction, further consuming energy, thereby inhibiting the transmission of vibration.

[0010] Further, the lateral surface of the second lateral frame is provided with a second installation slot, and an elastic steel plate and a connecting plate for fixing the elastic steel plate are installed in the second installation slot. The side surface of the connecting plate away from the elastic steel plate is fixedly connected with a plurality of polyurethane elastic blocks, and the polyurethane elastic blocks are tightly pressed in the gap of the second baffle plate.

[0011] Further, the pre-bent elastic steel plate always has a tendency to return to its original shape, thereby applying a continuous pressing force to the polyurethane elastic blocks through the connecting plate, so that the polyurethane elastic blocks are firmly embedded in the gap of the second baffle plate to ensure that the system can remain tight after long-term use and avoid loose and abnormal noise due to component wear. When vibrating, the polyurethane elastic blocks rub against the side wall of the baffle plate to consume energy; the tooth-shaped groove on the surface increases the friction area, improves the energy consumption efficiency and scatters sound waves.

[0012] Further, the surface of the first baffle plate is provided with a plurality of circular blind holes, and sound-absorbing cotton rods are inserted into the circular blind holes. The sound-absorbing cotton rods are arranged between adjacent second baffle plates, and the positions of the circular blind holes correspond to the gaps between the adjacent second baffle plates. The two ends of the sound-absorbing cotton rods are limited by stop blocks, and the side wall surface of the stop blocks is provided with anti-skid rubber strips that are tightly pressed against the inner wall of the circular blind hole.

[0013] Further, the circular blind holes are uniformly distributed on the second baffle surface, the stop blocks are circular rubber plugs, and the anti-skid rubber strips are raised ribs surrounding the side walls of the stop blocks. When the stop blocks are pressed into the end portions of the circular blind holes, the anti-skid rubber strips are elastically deformed and tightly pressed against the hole walls, so that the axial positioning of the sound-absorbing cotton strips and the sound sealing of the hole edges are realized.

[0014] Further, after the sound waves enter the blind holes on the second baffle surface, the sound waves penetrate into the porous sound-absorbing cotton strips. The sound waves force the air in the holes to vibrate and rub against the fiber networks of the sound-absorbing cotton, so that the sound energy is converted into heat energy and consumed. The stop blocks prevent the sound-absorbing cotton strips from falling off and seal the hole edges, so that the sound waves are not leaked from the hole edges without being absorbed, and the durability and effectiveness of the sound-absorbing performance are ensured.

[0015] Further, the threaded holes inside the clamping portions of the first and second lateral frames are coaxial through holes; the mounting bolts pass through the through holes of the first and second lateral frames and apply a pre-tightening force, so that the annular frame forms a rigid whole tightly clamped around the load-bearing base layer.

[0016] Further, the inner wall of the second connecting frame at the center is provided with a connecting hole, and the inner wall of the connecting hole of the second connecting frame is fixedly connected with two threaded rings, and the inner wall of the threaded ring corresponding to one side of the second connecting frame is threadedly connected with a reinforcing column.

[0017] Further, the reinforcing column is a rigid rod with external threads at both ends; the threaded ring is a connecting piece embedded in the inner wall of the second lateral frame; by screwing the reinforcing column, the depth of the two ends screwed into the threaded ring can be adjusted, so that the two second lateral frames are subjected to opposite tension forces, thereby enhancing the overall lateral stiffness and anti-overturning capacity of the intermediate shock insulation layer.

[0018] Further, the ends of the reinforcing column are screwed into the threaded rings fixed on the two side frames. By screwing to apply tension, the two side frames are tightly pulled towards each other, counteracting the horizontal component of the load from the upper part or the lateral moment generated by the operation of the equipment, preventing the overall system from being displaced or warped laterally.

[0019] Further, the side of the buffer block away from the first baffle is provided as an arc surface, and the buffer block is made of high-damping rubber material; the damping pad block is made of butyl rubber, and the side of the damping pad block pressed against the buffer block is provided as a matching arc surface matching the arc surface of the buffer block, and the arc surfaces of the damping pad block and the buffer block are tightly pressed.

[0020] Further, a plurality of tooth-shaped grooves are formed on the side surface of the polyurethane elastic block away from the connecting plate, for increasing the frictional energy dissipation with the side wall of the second baffle and destroying the regularity of sound waves.

[0021] Further, the buffer layer b is provided with a functional panel layer c, the functional panel layer c is a composite sound absorption panel, and the functional panel layer c is a prefabricated module composed of high-strength cement fiber board or metal perforated plate and sound absorption cotton.

[0051] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0052] Example 1

[0053] As Figures 1-5 shown, the application principle of the present application is further described below in combination with the accompanying drawings and specific embodiments.

[0054] An industrial building shock-absorbing and noise-reducing floor, characterized in that it comprises a load-bearing base layer 1a, which is the structural basis of the system and is made of high-performance concrete pouring and prefabrication, provides the main bearing strength and stiffness, and ensures that the entire floor system can stably support the upper equipment and load, and reliably transmits the static load and dynamic load of the equipment to the foundation.

[0055] A buffer layer 1b is installed on the surface of the load-bearing base layer 1a. The buffer layer 1b includes a frame 2 for connecting adjacent buffer layers 1b. The frame 2 forms a rigid outer boundary, integrating the internal vibration isolation and noise reduction modules into a unified whole. The preload provided by the mounting bolts ensures the firmness of the frame connection.

[0056] The frame 2 is composed of two first lateral frames 7 and two second lateral frames 8, which are interlocked by snap-fit ​​joints and secured with mounting bolts 9. The frame 2 is fixedly installed on the top surface and perimeter of the load-bearing base layer 1a, providing a mounting base and lateral constraints for all internal components. Its rigid connection ensures that the system will not loosen or deform under horizontal or torsional forces, ensuring that the vibration isolation modules 3 can work in a coordinated manner and effectively distribute local loads throughout the base layer.

[0057] The frame 2 is equipped with a vibration isolation module 3. The vibration isolation module 3 includes multiple support layers that are vertically arranged on the top surface of the load-bearing base 1a. The support layer includes a first baffle 4 and a second baffle 5 that are vertically arranged. The first baffle 4 and the second baffle 5 form an installation groove 401 at the edge of the buffer layer 1b. A buffer block 6 is fixedly inserted into the installation groove 401. The lateral surface of the first lateral frame 7 is provided with a first installation groove, in which a support frame 13 is inserted. Multiple damping pads 14 are fixedly connected to the side of the support frame 13 facing the inside of the system. The arc surface of the damping pad 14 is pressed against the side wall of the buffer block 6.

[0058] When vibration is transmitted from the panel layer, the buffer block 6 first undergoes compression deformation and shear deformation. The gap between the baffles provides the necessary deformation space for the buffer block. When the buffer block undergoes lateral deformation during vibration, it will squeeze the damping pad. The damping pad made of butyl rubber has a high loss factor and can convert the kinetic energy of the compression into heat energy through internal molecular friction, further consuming energy and thus suppressing the transmission of vibration.

[0059] The second lateral frame 8 has a second mounting groove on its lateral surface. An elastic steel plate 15 is installed inside the second mounting groove, and a connecting plate 16 is used to fix the elastic steel plate 15. A plurality of polyurethane elastic blocks 17 are fixedly connected to the side surface of the connecting plate 16 away from the elastic steel plate 15. The polyurethane elastic blocks 17 are pressed against the gap of the second baffle 5.

[0060] The pre-bent elastic steel plate 15 always tends to return to its original shape, thus applying a continuous clamping force to the polyurethane elastic block 17 through the connecting plate, making it firmly embedded in the gap of the second baffle 5. This ensures that the system remains tight even after long-term use, avoiding loosening and abnormal noise due to component wear. During vibration, the polyurethane elastic block 17 rubs against the side wall of the baffle, consuming energy; the toothed grooves on its surface increase the friction area, improve energy consumption efficiency, and scatter sound waves.

[0061] The surface of the first baffle 5 has multiple circular blind holes, and a sound-absorbing cotton strip 10 is inserted into the circular blind hole. The sound-absorbing cotton strip 10 is disposed between adjacent second baffles 5, and the position of the circular blind hole corresponds to the gap between adjacent second baffles 5. The two ends of the sound-absorbing cotton strip 10 are limited by a stop block 11. An anti-slip rubber strip 12 is installed on the side wall surface of the stop block 11, and the anti-slip rubber strip 12 is pressed tightly against the inner wall of the circular blind hole.

[0062] The circular blind holes are evenly distributed on the surface of the second baffle 5. The baffle 11 is a circular rubber plug. The anti-slip rubber strip 12 is a raised rib that surrounds the side wall of the baffle 11. When the baffle 11 is pressed into the end of the circular blind hole, the anti-slip rubber strip 12 undergoes elastic deformation and is tightly pressed against the hole wall, thereby achieving axial positioning of the sound-absorbing cotton strip 10 and acoustic sealing of the hole edge.

[0063] After the sound wave enters the blind hole on the surface of the second baffle 5, it penetrates deep into the porous sound-absorbing cotton strip 10. The sound wave forces the air inside the hole to vibrate, which rubs violently against the fiber ribs of the sound-absorbing cotton. The sound energy is thus converted into heat energy and consumed. The baffle 11 prevents the sound-absorbing cotton strip from falling off and seals the hole opening, preventing the sound wave from leaking out of the hole without being absorbed, thus ensuring the durability and effectiveness of the sound absorption performance.

[0064] The threaded holes inside the snap-fit ​​joint of the first lateral frame 7 and the second lateral frame 8 are coaxial through holes; the mounting bolts 9 pass through the through holes of the first lateral frame 7 and the second lateral frame 8 and apply pre-tightening force, so that the annular frame forms a rigid whole tightly bound to the load-bearing base 100.

[0065] The inner wall of the second connecting frame 8 at the center has a connecting hole. Two threaded rings 18 are fixedly connected to the inner wall of the connecting hole. A reinforcing column 19 is also threadedly connected to the inner wall of the threaded ring 18 on the corresponding side of the second connecting frame 8.

[0066] The reinforcing column 19 is a rigid rod with external threads at both ends; the threaded ring 18 is a connector embedded in the inner wall of the second lateral frame 8; by screwing the reinforcing column 19, the depth of its two ends screwed into the threaded ring 18 can be adjusted, thereby generating opposing tension forces on the two second lateral frames 8, enhancing the overall lateral stiffness and anti-overturning ability of the intermediate seismic isolation layer 200.

[0067] The two ends of the reinforcing column 19 are screwed into threaded rings fixed on the side frames. By screwing, a tensile force is applied, which tightly pulls the two side frames together to counteract the horizontal component of the load from the upper part or the lateral moment generated by the operation of the equipment, preventing the system as a whole from lateral displacement or warping.

[0068] The buffer block 6 is set with an arc surface on the side away from the first baffle 4, and the buffer block 6 is made of high damping rubber material; the damping pad 14 is made of butyl rubber, and the side of it pressed against the buffer block 6 is set with a matching arc surface that matches the arc surface of the buffer block 6, and the damping pad 14 is in close contact with the arc surface of the buffer block 6.

[0069] The polyurethane elastic block 17 has multiple toothed grooves on the side surface away from the connecting plate 16, which are used to increase the frictional energy dissipation with the side wall of the second baffle 5 and disrupt the regularity of the sound waves.

[0070] A functional panel layer 1c is installed on the buffer layer 1b. The functional panel layer 1c is a composite sound-absorbing panel, which is a prefabricated module made of high-strength cement fiberboard or metal perforated board and sound-absorbing cotton. The size of the functional panel layer 1c matches the inner dimensions of the frame 2.

[0072] A method for installing vibration-damping and noise-reducing flooring in industrial buildings includes the following steps:

[0073] S1. Install load-bearing base layer 1a: Install load-bearing base layer 1a according to the plan, and reserve installation space for the frame 2 when installing load-bearing base layer 1a;

[0074] S2. Install the buffer layer; vertically install the integrated support layer on the load-bearing base 1a, and install the sound-absorbing cotton strip 10 through the circular blind hole, and install the stop block 11 to limit the sound-absorbing cotton strip 10; install the buffer block 6 in the installation groove 401, and after the buffer block 6 is installed, install the connecting plate 16 and the elastic steel plate 15 in sequence, and finally install the frame frame 2.
