At the same time, under vibration, the air inside the shell enters and exits through the gap between the metal disc and the flexible sound insulation layer on the side wall, generating energy consumption and silencing.

[0022] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following detailed description of the solution according to the present invention is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] This application discloses a built-in elevated integrated thermal insulation and soundproof floor system.

[0024] Reference Figures 1-2The system includes an integrated elevated thermal insulation and soundproof floor slab system, primarily comprising a precast floor slab 1 with a thickness of 5-10cm, and an insulation layer 2 with a thickness of 2-4cm above the precast floor slab 1. The insulation layer 2 has an array of pre-drilled holes, with adjacent holes spaced 20-60cm apart. Soundproof support columns 3 are inserted into the pre-drilled holes. These support columns are arranged in an array on the insulation layer 2. Each soundproof support column 3 includes a cylindrical outer shell 31. The outer contour of the bottom of the outer shell 31 is fitted and fixed to the inner contour of the pre-drilled holes. The inner bottom wall of the outer shell 31 is lined with a bottom flexible soundproof layer 32, and the inner side wall of the outer shell 31 is lined with a side wall flexible soundproof layer 33. The bottom flexible soundproof layer 32 is bonded to the bottom of the outer shell 31. The side wall flexible soundproof layer 33 is bonded to the inner side wall of the outer shell 31 and has a large height. A tubular structure at half the height of the outer shell 31; the bottom flexible sound insulation layer 32 and the side wall flexible sound insulation layer 33 cover the entire bottom of the outer shell 31; a vertical bolt 34 is centrally located inside the outer shell 31, the bolt head of the bolt 34 is pressed onto the bottom flexible sound insulation layer 32 and bonded and fixed; a support plate 35 with a threaded hole in the middle is threadedly connected to the bolt 34; an annular flange 36 facing downward is provided on the support plate 35; the annular flange 36 and the upper part of the outer shell 31 are fitted together and form a sliding fit; an elastic sealing ring 37 is provided at the overlap of the annular flange 36 and the outer shell 31; a cast-in-place concrete 4 is provided above the insulation layer 2; a raised floor 5 is installed above the cast-in-place concrete 4 through an array of sound insulation columns; a cavity layer 6 is formed between the raised floor 5 and the cast-in-place concrete 4.

[0025] Furthermore, the radial cross-sectional area of ​​the support plate 35 is 30~80cm², and the thickness is 0.8~2cm.

[0026] Furthermore, the height of the outer shell 31 is 5-14cm; the thickness of the cast-in-place concrete 4 covers 80%-95% of the height of the outer shell 31; and the spacing of the cavity layers 6 is 1-2cm.

[0027] The precast floor slab 1, insulation layer 2, sound insulation support array, cast-in-place concrete 4, cavity layer 6, and raised floor 5 constitute the overall floor slab.

[0028] An insulation layer 2 with a thickness of 2-4cm is sandwiched between the precast floor slab 1 and the cast-in-place concrete 4, which can reduce the heat transfer through the cast-in-place concrete 4 and ensure the overall insulation performance of the floor slab.

[0029] The bottom outer contour of the outer shell 31 and the inner wall contour of the reserved hole are adapted to be plugged and fixed, which allows the inner wall of the reserved hole and the outer wall of the outer shell 31 to fit together, restricting the position of the sound insulation column 3 and making the sound insulation column 3 stable during the pouring of cast-in-place concrete 4.

[0030] Compared to the traditional 5-point support method for raised floors, in the sound insulation column array, the spacing between adjacent sound insulation columns 3 is 20~60cm, the radial cross-sectional area of ​​the support plate 35 is 30~80cm², and the thickness of the support plate 35 is 0.8~2cm. Through this design, sufficient support surface and sufficient support strength can be provided for the raised floor 5. The raised floor 5 is not easy to crack due to insufficient stress area and is more stable.

[0031] The flexible sound insulation layer 33 on the side wall, which is half the height of the outer shell 31, and the flexible sound insulation layer 32 on the bottom are used together. When sound wave energy is transmitted through the support plate 35 and the bolts 34, the flexible sound insulation layer 33 on the side wall and the flexible sound insulation layer 32 on the bottom can absorb sound, thus ensuring the sound insulation performance of the entire floor slab.

[0032] The support plate 35 is threaded onto the bolt 34. On-site installers can adjust the elevation according to the required height to meet the different installation height needs of the raised floor 5.

[0033] Specifically, the annular flange 36 is coaxially disposed on the outer side of the upper part of the housing 31, the elastic sealing ring 37 is fixedly installed on the outer side wall of the annular flange 36, and the elastic thin metal ring 38 covers the upper part of the housing 31, which can reduce the entry of external dust into the housing 31.

[0034] In addition, the design of an elastic sealing ring between the annular flange 36 and the upper part of the outer shell 31 allows the elastic sealing ring 37 to rub against the upper part of the outer shell 31 when the support plate 35 vibrates up and down due to the vibration of the raised floor 5, thereby consuming sound wave energy and further improving the sound insulation effect of the sound insulation column 3 and enhancing the overall sound insulation performance of the floor slab.

[0035] The thickness of the cast-in-place concrete 4, covering 80% to 95% of the height of the outer shell 31, allows 80% to 95% of the outer shell to be embedded in the pre-drilled holes and the cast-in-place concrete 4. Since the sound-absorbing support itself has good sound insulation properties, the overall sound insulation of the floor slab is guaranteed. This technology ensures that, with sufficient sound insulation, the height of the outer shell 31 can be only 5 to 14 cm, and the thickness of the cavity layer 6 can be only 1 to 2 cm, saving the overall height of the floor slab and reducing the impact on the usable ceiling height.

[0036] Furthermore, refer to Figure 1 The precast floor slab 1 is embedded with a lower steel mesh 11; a steel truss 7 is tied above the lower steel mesh 11, and a part of the steel truss 7 is embedded in the precast floor slab 1; the upper part of the steel truss 7 passes through the insulation layer 2, and an upper steel mesh 41 is tied above the steel truss 7; the portions of the upper steel mesh 41 and the steel truss 7 that pass through the insulation layer 2 are embedded in the cast-in-place concrete 4.

[0037] By combining the steel truss 7, the lower steel mesh 11, and the upper steel mesh 41, the connection between the precast floor slab 1 and the cast-in-place concrete 4 can be achieved through the steel truss 7, thereby improving the overall load-bearing capacity and crack resistance of the floor slab.

[0038] Furthermore, the raised floor 5 has an isolation layer 8 along its edge; the bottom of the isolation layer 8 is bonded and fixed to the top of the cast-in-place concrete 4; the side of the isolation layer 8 closest to the wall 9 is bonded and fixed to the wall 9; the side of the isolation layer 8 furthest from the wall 9 is bonded and fixed to the outer edge of the raised floor 5; the height of the isolation layer 8 covers 85% to 100% of the raised floor 5.

[0039] Specifically, the isolation layer 8 is made of polyurethane rubber (which can be customized according to the needs of the application scenario), which has good elasticity, wear resistance and is not easy to age.

[0040] The isolation layer 8 can seal the raised floor 5, the wall 9 and the cast-in-place concrete 4, improve the sealing of the cavity layer 6, further improve the sound insulation of the overall floor slab, and at the same time ensure the moisture-proof performance of the overall floor slab.

[0041] Furthermore, a nut 351 is provided on the support plate 35, and the nut 351 is threadedly connected to the bolt 34.

[0042] The nut 351 is used in conjunction with a screwdriver. During installation, the on-site installer can use the screwdriver to rotate the support plate 35 in different directions to adjust the height of the support plate 35.

[0043] The bottom of the raised floor 5 is provided with an array of blind holes. Through the blind holes, the portion of the screw that protrudes from the support plate 35 and the nut 351 can be avoided, thereby allowing the raised floor 5 to directly contact the support plate 35.

[0044] Furthermore, a metal disc 39 is provided in the middle of the shank of the bolt 34. The outer edge of the metal disc 39 supports the inner side of the flexible sound insulation layer 33 of the tubular structure, forming an airtight cavity below the metal disc 39.

[0045] The metal disc 39 can support and position the bolt 34, improving the stability of the bolt 34, and can further improve the stability of the support disc 35 installed on the bolt 34 for supporting the raised floor 5.

[0046] Under vibration, energy can be dissipated by the deformation of the bolt 34 and the bottom flexible sound insulation layer at the bottom of the bolt 34, and the vibration is not transmitted to the concrete floor slab, thus achieving the purpose of sound insulation; at the same time, under the action of vibration, the air inside the outer shell 31 enters and exits through the gap between the metal disk 39 and the side wall flexible sound insulation layer 33, generating energy consumption and silencing.

[0047] In addition, the metal disc 39 is not easily deformed, and the bolt 34 can remain stable for a long time under the support of the metal disc 39. Specific Implementation Example 1:

[0049] A thin, elastic metal ring 38 is fixedly connected to the lower part of the support plate 35. The thin, elastic metal ring 38 is an austenitic stainless steel ring with a thickness of 0.1~0.3mm. The annular flange 36 is an austenitic stainless steel flange integrally formed at the edge of the austenitic stainless steel ring with a thickness of 0.1~0.3mm. The 0.1~0.3mm thick austenitic stainless steel ring and austenitic stainless steel flange have good elasticity, forming a vibration energy absorption area at the edge of the support plate 35. When the support plate 35 vibrates up and down due to the influence of the raised floor 5, the thin, elastic metal ring 38 and the austenitic stainless steel flange vibrate in tandem under the action of the support plate 35, consuming sound wave energy. Specific Implementation Example 2:

[0051] After the elastic sealing ring 37 is disposed between the annular flange 36 and the outer shell 31, it forms an elastic cavity structure below the support plate 35 for shrinking and expanding to reduce noise.

[0052] When the support plate 35 vibrates up and down due to the vibration of the raised floor 5, the air inside the outer shell 31 enters and exits through the gap between the elastic sealing ring 37 and the outer shell 31 wall with a thickness of 0.1~0.3mm, and expands and contracts to reduce noise, further improving the overall sound insulation effect of the floor slab. Specific Implementation Example 3:

[0054] The insulation layer 2 is a rock wool layer.

[0055] The rock wool layer has good thermal insulation properties, which can reduce the heat transfer through the entire floor slab, thus giving the entire floor slab good thermal insulation properties.

[0056] Rock wool itself has good sound absorption properties, which can reduce the transmission of sound wave energy through the entire floor slab and further improve the sound insulation effect of the entire floor slab.

[0057] The rock wool layer has good fire resistance and can form a fireproof shield between the precast floor slab 1 and the cast-in-place concrete 4, ensuring the overall fire resistance of the floor slab. Specific Implementation Example 4:

[0059] The insulation layer 2 is granulated concrete poured on top of the precast floor slab 1.

[0060] Granulated concrete can ensure the thermal insulation, sound insulation and fire resistance of the entire floor slab.

[0061] At the same time, granulated concrete has high load-bearing capacity and deformation resistance, which can provide stable support for cast-in-place concrete 4. Specific Implementation Example 5:

[0063] The insulation layer 2 is an XPS insulation board.

[0064] XPS insulation boards are laid on the surface of concrete, which can ensure the overall insulation performance of the floor slab, while giving the insulation layer 2 good compressive strength and moisture resistance, and can also reduce the self-weight of the overall floor slab. Specific Implementation Example Six:

[0066] The reserved hole is a blind hole, and the depth of the blind hole is 2 / 3 to 3 / 4 of the height of the insulation layer 2.

[0067] By setting the reserved holes as blind holes, 1 / 4 to 1 / 3 of the insulation layer 2 can be placed under the outer shell 31, reducing the transfer of heat and sound wave energy to the precast floor slab 1 through the outer shell 31, and further improving the overall insulation and sound insulation performance of the floor slab. Specific Implementation Example 7:

[0069] The side wall flexible sound insulation layer 33 and the bottom flexible sound insulation layer 32 are rock wool layers.

[0070] The rock wool layer not only provides good sound insulation, but also makes the side wall flexible sound insulation layer 33 and the bottom flexible sound insulation layer 32 fireproof and resistant to aging. Specific Implementation Example 8:

[0072] Both the side wall flexible sound insulation layer 33 and the bottom flexible sound insulation layer 32 are rubber layers.

[0073] The rubber layer achieves good sound insulation while also providing good moisture resistance to the side wall flexible sound insulation layer 33 and the bottom flexible sound insulation layer 32. Specific Implementation Example Nine:

[0075] The side wall flexible sound insulation layer 33 is a rubber layer, and the bottom flexible sound insulation layer 32 is a rock wool layer.

[0076] By bonding the rubber layer inside the outer shell 31, the vibration of the outer shell 31 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 34. This achieves overall anti-aging while ensuring sufficiently good sound insulation and noise reduction performance.

[0077] The weighted normalized impact sound pressure level index value of this invention was tested. The test results are shown in the table below.

[0079] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. It should not be construed that the specific implementation of the present invention 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 invention should be covered within the protection scope of the present invention.
