Technical Field

[0001] This application relates to the field of building structural components, and in particular to sound insulation supports for floor slabs. Background Technology

[0002] To improve sound insulation between floors, raised floor designs are often used. A typical raised floor consists of a raised floor panel and a floor finish. The floor finish is laid on the upper surface of the raised floor panel, allowing for various decorative effects such as flooring, tiles, and stone. The raised floor is supported on a precast floor slab by panel legs.

[0003] However, sound can still easily be transmitted through the panel legs, making it difficult to guarantee sound insulation. Utility Model Content

[0011] The flexible sound insulation layer on the side wall is attached to the inner side wall of the shell, and the flexible sound insulation layer at the bottom is attached to the inner bottom wall of the shell, thus covering the entire bottom of the shell.

[0012] Preferred,

[0013] The outer shell is cylindrical;

[0014] The support disk is disc-shaped;

[0015] The bottom flexible sound insulation layer is a circular structure that is attached to the inner wall of the bottom of the outer shell;

[0016] The bottom of the flexible sound insulation layer on the side wall of the tubular structure is fixedly connected to the top of the flexible sound insulation layer at the bottom of the circular structure.

[0017] Preferably, both the sidewall flexible sound insulation layer and the bottom flexible sound insulation layer are rubber layers.

[0018] Preferably, both the sidewall flexible sound insulation layer and the bottom flexible sound insulation layer are rock wool layers.

[0019] Preferably, the sidewall flexible sound insulation layer is a rubber layer, which is bonded to the inner sidewall of the outer shell, and the bottom flexible sound insulation layer is a rock wool layer.

[0020] Preferably, the outer shell is a galvanized thin steel shell integrally die-cast;

[0021] The thickness of the outer shell is 1~5mm;

[0022] The wall thickness of the outer shell is 0.1~0.3mm;

[0023] The height of the outer shell is 3~10cm.

[0024] Preferably, the bolt shank extends at least partially above the support plate, and a protective cap is threaded onto the portion of the bolt shank that extends through.

[0025] Preferably, a nut is fixedly connected to the support plate, and the nut is threadedly connected to the bolt's screw.

[0026] Preferably, a rigid disc is provided in the middle of the bolt shank, and the outer edge of the rigid disc supports the inner side of the tubular structure, forming an airtight cavity below the rigid disc.

[0027] Preferably, the hard disk has a threaded hole in the middle, and the hard disk is threadedly connected to the bolt shank through the threaded hole.

[0028] Preferably, the hard disk is a metal disk.

[0029] Preferably, the bottom edge of the support plate is integrally formed with a downward-facing annular flange, and the annular flange is coaxially disposed on the inner side of the outer shell;

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. The support plate and bolts are used to support the overhead components. Since the support plate and bolts are installed inside the shell, and the shell is equipped with a flexible sound insulation layer on the side wall and a flexible sound insulation layer at the bottom, the sound transmitted by the support plate and bolts can be reduced, thus ensuring the sound insulation effect of the floor sound insulation column.

[0035] 2. During installation, the outer shell can be pre-embedded in the precast floor slab. Since the sound insulation support column of the floor slab itself has a good sound insulation effect, it can ensure the sound insulation effect of the entire floor slab. This technology ensures that the height of the outer shell can be only 3~10cm while having sufficient sound insulation effect, saving the overall height of the floor slab and reducing the impact on the net height of the entire floor slab.

[0036] 3. Since the support plate is threaded onto the bolt shank, the height of the support plate can be easily adjusted according to the actual installation height requirements, thus improving the usability of the floor sound insulation support column;

[0037] 4. Due to the large contact area between the support plate and the supported component, cracking of the plate-shaped supported component can be effectively reduced. Attached Figure Description

[0042] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the following detailed description of the solution based on this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0043] This application discloses floor sound insulation supports in its embodiments.

[0044] Reference Figure 1 The floor slab sound insulation support mainly includes bolts 1 and cylindrical shell 2. The inner side wall of the shell 2 is lined with a side wall flexible sound insulation layer 21, and the bottom inner wall of the shell 2 is lined with a bottom flexible sound insulation layer 22. The bolt 1 is vertically arranged in the middle of the outer shell 2, and the bolt head of the bolt 1 is pressed onto the bottom flexible sound insulation layer 22 and fixed in place; A support plate 3 is threadedly connected to the bolt 1. The support plate 3 is supported below the supported part. A threaded hole is opened in the middle of the support plate 3. The support plate 3 is threadedly connected to the bolt 1 through the threaded hole. The flexible sound insulation layer 21 on the side wall is a tubular structure that is attached and fixed to the inner side wall of the outer shell 2, and its height is higher than half the height of the outer shell 2; The bottom flexible sound insulation layer 22 is a structure that is attached and fixed to the bottom inner wall of the outer shell 2; The sidewall flexible sound insulation layer 21 is attached to the inner sidewall of the outer shell 2, and the bottom flexible sound insulation layer 22 is attached to the bottom inner wall of the outer shell 2, covering the entire bottom of the outer shell 2.

[0045] The supported component is a raised floor. The outer shell 2 is installed on the precast concrete floor slab, and the support plate 3 is supported on the bottom of the raised floor, thus achieving the technical effect of suspending the raised floor above the precast floor slab.

[0046] When sound propagates through the support plate 3 and bolt 1, the bottom flexible sound insulation layer 22 and the side wall flexible sound insulation layer 21 can absorb sound, thereby achieving a sound insulation effect.

[0047] Since the support plate 3 is connected to the screw rod through a threaded hole, on-site installers can adjust the height of the support plate 3 by turning it in different directions according to the required installation height of the supported component, so as to meet the installation requirements of different heights.

[0048] In addition, since the floor sound insulation column supports the raised floor through the support plate 3, compared with the point support of the traditional panel leg, the contact surface between the support plate 3 and the supported component is larger, which can reduce the situation where the supported component cracks and is damaged due to excessive force concentration.

[0049] The outer shell 2 is a galvanized thin steel shell 2 integrally die-cast; the bottom thickness of the outer shell 2 is 1~5mm; the wall thickness of the outer shell 2 is 0.1~0.3mm; and the height of the outer shell 2 is 3~10cm.

[0050] The bottom wall of the outer casing 2, with a thickness of 1~5mm, provides sufficient support for the bolts 1 inside.

[0051] When the sound wave energy is transmitted to the outer shell 2, the side wall of the outer shell 2, which has a wall thickness of 0.1~0.3mm, undergoes a slight elastic deformation, which further consumes the sound wave energy and can further improve the sound insulation effect of the floor sound insulation column.

[0052] The raised floor, the sound insulation support columns of the floor slab, and the precast floor slab together form an integral floor slab.

[0053] During installation, the outer shell 2 can be pre-embedded in the precast floor slab. Since the floor slab sound insulation support itself has a good sound insulation effect, it can ensure the sound insulation effect of the entire floor slab. This technology ensures that with sufficient sound insulation, the height of the outer shell 2 can be only 3~10cm, saving the overall height of the floor slab and reducing the impact on the net height of the entire floor slab.

[0054] Reference Figure 1 The bolt 1 has at least a portion of its thread extending above the support plate 3, and a protective cover 5 is threaded onto the portion of the bolt 1 that has its thread extending through.

[0055] The protective cover 5 can cover and protect the part of the screw that protrudes from the support plate 3, preventing the part of the screw that protrudes from the support plate 3 from being contaminated during the installation of the floor sound insulation column.

[0056] During installation, on-site operators can unscrew the protective cover 5 to facilitate subsequent adjustment of the height of the support plate 3.

[0057] A nut 6 is fixedly connected to the support plate 3, and the nut 6 is threadedly connected to the bolt 1.

[0058] The nut 6 is used in conjunction with a screwdriver. During installation, the on-site installer can use the screwdriver to rotate the support plate 3 in different directions to adjust the height of the support plate 3.

[0059] The bottom of the raised floor has a slot, through which the part of the screw that protrudes from the support plate 3 and the nut 6 can be avoided, so that the raised floor can directly contact the support plate 3.

[0060] Reference Figure 1 A rigid disc 7 is provided in the middle of the bolt 1. The outer edge of the rigid disc 7 supports the inner side of the tubular structure, forming an airtight cavity below the rigid disc 7.

[0061] By supporting the tubular structure with a rigid disc 7, the vertically installed bolt 1 can be positioned inside the outer casing 2, thereby improving the stability of the bolt 1.

[0062] The hard disk 7 has a threaded hole in the middle, and the hard disk 7 is threaded to the bolt 1 through the threaded hole, so that the hard disk 7 is suspended in the middle of the outer shell 2.

[0063] Furthermore, when bolt 1 vibrates due to the raised floor, air inside the outer casing 2 enters and exits through the gap between the rigid disk 7 and the flexible sound insulation layer 21 on the side wall under the action of bolt 1. This generates energy consumption and thus reduces noise.

[0064] Furthermore, the rigid disc 7 is a metal disc. The metal disc is not easily deformed, and the bolt 1 can remain stable over a long period of time with the support of the metal disc. Specific Implementation Example 1:

[0066] The outer shell 2 is cylindrical; the support plate 3 is disc-shaped; the bottom flexible sound insulation layer 22 is a circular structure attached to the inner wall of the bottom of the outer shell 2; the bottom of the tubular side wall flexible sound insulation layer 21 is fixedly connected to the top of the circular bottom flexible sound insulation layer 22.

[0067] By designing the outer shell 2 as a cylinder and the support plate 3 as a disc, interference between the support plate 3 and the outer shell 2 can be reduced during the adjustment of the height of the support plate 3, making it easier to adjust the support plate 3 by turning it. Specific Implementation Example 2:

[0069] Both the sidewall flexible sound insulation layer 21 and the bottom flexible sound insulation layer 22 are rubber layers.

[0070] The rubber layer achieves good sound insulation while also providing excellent moisture resistance to the side wall flexible sound insulation layer 21 and the bottom flexible sound insulation layer 22. In humid environments, this reduces the likelihood of the side wall flexible sound insulation layer 21 and the bottom flexible sound insulation layer 22 experiencing a decline in sound insulation performance due to moisture. Specific Implementation Example 3:

[0072] Both the sidewall flexible sound insulation layer 21 and the bottom flexible sound insulation layer 22 are rock wool layers.

[0073] The rock wool layer not only provides good sound insulation, but also makes the side wall flexible sound insulation layer 21 and the bottom flexible sound insulation layer 22 have good fire resistance and are not prone to aging. Specific Implementation Example 4:

[0075] The sidewall flexible sound insulation layer 21 is a rubber layer, and the bottom flexible sound insulation layer 22 is a rock wool layer; the rubber layer is bonded to the inner sidewall of the outer shell 2.

[0076] By bonding the rubber layer to the inside of the outer shell 2, the vibration of the outer shell 2 is transmitted to the rubber layer, achieving linked vibration and further ensuring overall sound absorption and insulation performance. The rock wool layer has good pressure resistance and wear resistance, and provides good mechanical properties for supporting bolts 1. This achieves overall anti-aging while ensuring sufficiently good sound insulation and noise reduction performance. Specific Implementation Example 5:

[0078] Reference Figure 2 The bottom edge of the support plate 3 is integrally formed with a downward-facing annular flange 31, which is coaxially disposed on the inner side of the outer shell 2. The outer edge of the annular flange 31 is fixed with an elastic sealing ring 4 for sound insulation, and the elastic sealing ring 4 slides in contact with the inner wall of the outer shell 2.

[0079] The edge (annular flange 31) of the support plate 3 is affected by the vibration of the raised floor, causing it to vibrate up and down, which in turn causes the elastic sealing ring 4 to slide against the inner wall of the outer shell 2.

[0080] The elastic sealing ring 4 slides against the inner wall of the outer shell 2, generating friction and energy consumption, thus reducing noise.

[0081] Simultaneously, as the elastic sealing ring 4 slides against the inner wall of the outer shell 2, air inside the outer shell 2 enters and exits through the gap between the elastic sealing ring 4 and the inner wall of the outer shell 2. This generates energy consumption and thus reduces noise. Specific Implementation Example Six:

[0083] Reference Figure 3 The bottom edge of the support plate 3 is integrally formed with a downward-facing annular flange 31, which is coaxially sleeved on the outside of the outer shell 2. The inner wall of the support plate 3 is fixed with an elastic sealing ring 4 for sound insulation, and the elastic sealing ring 4 slides with the outer wall of the outer shell 2.

[0084] The edge (annular flange 31) of the support plate 3 is affected by the vibration of the raised floor, causing it to vibrate up and down, which in turn causes the elastic sealing ring 4 to slide against the inner wall of the outer shell 2.

[0085] The elastic sealing ring 4 slides against the inner wall of the outer shell 2, generating friction and energy consumption, thus reducing noise.

[0086] Meanwhile, as the elastic sealing ring 4 slides against the inner wall of the outer shell 2, the air inside the outer shell 2 enters and exits through the gap between the elastic sealing ring 4 and the outer wall of the outer shell 2, generating energy consumption and thus reducing noise.

[0087] In addition, through the above design, the support plate 3 completely covers the top of the outer shell 2, which can prevent the inside of the outer shell 2 from being contaminated by dust.

[0088] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, any equivalent changes made to the structure, shape, and principle of this application without departing from the concept of the present utility model should be covered within the protection scope of the present utility model.
