Description

A floor slab capable of vibration reduction and noise reduction Technical Field

[0001] This utility model relates to the field of building floor slab technology, specifically a floor slab capable of vibration reduction and noise reduction. Background Technology

[0002] As the load-bearing component of a floor slab, a floor slab vertically divides a building into several floors and transfers the vertical load and its own weight to the foundation through walls, beams, or columns. In temporary buildings, modular floor slabs are typically used to assemble the floor slabs. These modular floor slabs are usually prefabricated on-site or at the construction site and then assembled.

[0003] A search revealed that this utility model, based on Chinese Patent Publication No. CN 218149154 U, provides a seismic-resistant and noise-reducing floor slab. The aim is to address the technical problems of poor seismic resistance and high noise levels in existing floor slabs constructed in high-ceiling rooms. The floor slab includes: load-bearing beams, with several beams fixed parallel to each other to a wall; several support rods, all disposed on the load-bearing beams, the support rods being horizontal and perpendicular to the load-bearing beams; a cover plate laid on all the support rods; a top plate located at the bottom of the load-bearing beams; and sponge filling the space between the cover plate and the top plate. The support rods and load-bearing beams are all located within square tubing, and the specifications of the support rods are smaller than those of the load-bearing beams, while the density of the support rods is greater than the density of the load-bearing beams. This floor slab offers advantages in both seismic resistance and sound insulation.

[0004] The floor slabs in the aforementioned patent still have certain shortcomings. Due to insufficient thickness and low rigidity of floor slabs in many existing commercial buildings, sound insulation and vibration isolation effects are poor, often causing conflicts and disputes between upper and lower floors. Therefore, a method is proposed that by adding floor slab reinforcements and sound-absorbing insulation layers to the bottom of existing floor slabs, the rigidity and sound insulation and vibration isolation effects of floor slabs can be greatly improved, making it usable by users. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, this utility model provides a floor slab that can reduce vibration and noise, which solves the problem that the floor slabs in many existing commercial buildings are not thick enough, have low rigidity, and have poor sound insulation and vibration isolation effects, often causing conflicts and disputes between upper and lower floors.

[0006] This utility model provides the following technical solution: a floor slab capable of shock absorption and noise reduction, including a wall, a floor slab body is provided on the wall, a ceiling plate is provided at the bottom of the floor slab body, and a shock absorption and noise reduction component is provided between the floor slab body and the ceiling plate;

[0007] The vibration damping and noise reduction component includes two square support steel pipes symmetrically arranged at the bottom of the floor slab. Several mounting holes are evenly opened on the square support steel pipes. Vibration damping rubber pads are provided on the top of each square support steel pipe. Several pre-embedded holes are symmetrically opened at the bottom of the floor slab. Several connecting holes are evenly and symmetrically opened on the ceiling plate. Expansion bolts are inserted into each connecting hole. The top of the expansion bolts passes through the mounting holes and is inserted into the pre-embedded holes. Fastening nuts are fitted on the bottom of the expansion bolts. A first sound-absorbing and heat-insulating board is provided between the two square support steel pipes.

[0008] Preferred technical solution 1: The square supporting steel pipe is also provided with a second sound-absorbing and heat-insulating board on its side, and two side baffles are symmetrically provided on both sides of the top of the ceiling panel.

[0009] Preferred technical solution 2: The top of each side baffle is provided with a connecting rubber strip, and the bottom of the side baffle is fixedly connected to the ceiling panel by a number of inserted fastening screws.

[0010] Preferred technical solution 3: The vibration isolation rubber pad has a plurality of mounting holes evenly distributed on it, and the mounting holes are all penetrated by the expansion bolts.

[0011] This solution enables the vibration-damping rubber pads installed on top of the square support steel pipes to make more stable contact with the main floor slab.

[0012] Preferred technical solution four: The top surface of the first sound-absorbing and heat-insulating board is attached to the main body of the floor slab, and the bottom side surface of the first sound-absorbing and heat-insulating board is attached to the ceiling panel.

[0013] This solution enables the first sound-absorbing and heat-insulating board to achieve better sound insulation and vibration isolation effects.

[0014] Preferred technical solution five: The second sound-absorbing and heat-insulating board fills the space between the square supporting steel pipe and the side baffle.

[0015] This solution enables the second sound-absorbing and heat-insulating board to be distributed between the floor slab and the ceiling panel, achieving better sound insulation and vibration isolation effects.

[0016] Compared with the prior art, this utility model provides a floor slab that can reduce vibration and noise, and has the following beneficial effects:

[0017] (1) This utility model provides a vibration damping and noise reduction component between the floor slab and the ceiling slab. The square support steel pipe in the vibration damping and noise reduction component is fixedly connected to the ceiling slab and the floor slab through the expansion bolts inserted on it. This provides a limiting and fixing for the first sound-absorbing and heat-insulating board and the second sound-absorbing and heat-insulating board filled between the floor slab and the ceiling slab. The first sound-absorbing and heat-insulating board and the second sound-absorbing and heat-insulating board achieve good sound insulation and vibration isolation effects. The vibration isolation rubber pad is set at the junction of the square support steel pipe and the floor slab, which can also play a certain vibration reduction effect. This effectively reduces the impact of the noise generated by the activities of the residents on the upper floor of the floor slab on the lives of the residents on the lower floor.

[0024] Please refer to Figure 1-4.

[0025] Example 1: A floor slab capable of vibration reduction and noise reduction includes a wall 1, a floor slab body 2 installed on the wall 1, a ceiling panel 3 installed at the bottom of the floor slab body 2, and a vibration reduction and noise reduction component 4 installed between the floor slab body 2 and the ceiling panel 3.

[0026] The vibration damping and noise reduction component 4 includes two square support steel pipes 401 symmetrically arranged at the bottom of the floor slab body 2. Several mounting holes 402 are evenly distributed on the square support steel pipes 401. Vibration-damping rubber pads 403 are installed on the top of each square support steel pipe 401. Several pre-embedded holes 404 are symmetrically distributed at the bottom of the floor slab body 2. Several connecting holes 405 are evenly distributed and symmetrically distributed on the ceiling panel 3. Expansion bolts 406 are inserted into each connecting hole 405, with the top of the expansion bolts 406 penetrating through the mounting holes 402. The expansion bolt 406 is inserted into the pre-embedded hole 404, and the bottom end of the expansion bolt 406 is fitted with a fastening nut 407. A first sound-absorbing and heat-insulating board 408 is set between the two square support steel pipes 401. A second sound-absorbing and heat-insulating board 409 is also set on the side of the square support steel pipe 401. Two side baffles 410 are symmetrically arranged on both sides of the top of the ceiling panel 3. A connecting rubber strip 411 is set on the top of each side baffle 410. The bottom end of the side baffle 410 is fixedly connected to the ceiling panel 3 by a number of fastening screws 412 inserted.

[0027] Example 2: The difference between this example and Example 1 is that the vibration isolation rubber pad 403 has several mounting holes evenly distributed on it, and the mounting holes are all penetrated by expansion bolts 406.

[0028] This makes the vibration isolation rubber pad 403, which is set on top of the square support steel pipe 401, more stably contact the main body of the floor slab 2.

[0029] Example 3: The difference between this example and Example 1 is that the top surface of the first sound-absorbing and heat-insulating board 408 is attached to the floor slab body 2, and the bottom side surface of the first sound-absorbing and heat-insulating board 408 is attached to the ceiling board 3.

[0030] This allows the first sound-absorbing and heat-insulating board 408 to achieve better sound insulation and vibration isolation effects.

[0031] Example 4: The difference between this example and Example 1 is that the second sound-absorbing and heat-insulating board 409 fills the space between the square supporting steel pipe 401 and the side baffle 410.

[0032] This allows the second sound-absorbing and heat-insulating board 409 to be distributed between the main floor slab 2 and the ceiling board 3, thus achieving better sound insulation and vibration isolation effects.

[0033] In this embodiment, because the floor slab thickness is insufficient and the slab rigidity is low in many existing commercial buildings, the sound insulation and vibration isolation effects are poor, which often causes conflicts and disputes between the upper and lower floors.

[0034] In summary, in specific implementation, a vibration damping and noise reduction component 4 is installed between the floor slab body 2 and the ceiling slab 3. An expansion bolt 406 is inserted into the square support steel pipe 401 in the vibration damping and noise reduction component 4. The top of the expansion bolt 406 passes through the connecting hole 405 and the installation hole 402 in sequence and is inserted into the pre-embedded hole 404 opened on the bottom side of the floor slab body 2. A fastening nut 407 is fitted onto the bottom end of the expansion bolt 406, thereby firmly connecting the ceiling slab 3 and the square support steel pipe 401 with the floor slab body 2.

[0035] Vibration-damping rubber pads 403 are installed at the junction of the square support steel pipe 401 and the floor slab body 2. The vibration-damping rubber pads 403 can reduce the vibration of the floor slab body 2 and reduce the transmission of vibration force to the square support steel pipe 401, thus achieving a certain vibration isolation effect. A first sound-absorbing and heat-insulating board 408 is filled between the two square support steel pipes 401, and a second sound-absorbing and heat-insulating board 409 is filled between the square support steel pipe 401 and the side baffle 410. Through the action of the first sound-absorbing and heat-insulating board 408 and the second sound-absorbing and heat-insulating board 409, the vibration and noise generated on the floor slab body 2 can be effectively isolated and vibration-damped, so as to reduce the impact of loud noise from upstairs on the daily life of downstairs users.

[0036] The side baffle 410 located on the outside of the second sound-absorbing and heat-insulating board 409 can abut against the side of the second sound-absorbing and heat-insulating board 409, better blocking the second sound-absorbing and heat-insulating board 409 and ensuring its stability. The side baffle 410 is fixedly connected to the ceiling board 3 by the fastening screws 412. The device can connect the floor slab body 2 and the ceiling board 3 through the square support steel pipe 401, thereby providing limiting support for the first sound-absorbing and heat-insulating board 408 and the second sound-absorbing and heat-insulating board 409. The first sound-absorbing and heat-insulating board 408 and the second sound-absorbing and heat-insulating board 409 fill the space between the floor slab body 2 and the ceiling board 3, which can effectively achieve sound insulation and vibration isolation, so that the vertical movement of the floor slab body 2 will not affect each other much, improving the user's living comfort.
