[0026] Example 1

[0027] Combined with appendix Figure 1 To be continued Figure 3 This embodiment proposes a composite thermal insulation and sound insulation pad, including a thermal insulation and sound insulation layer 1 and a three-dimensional crack-resistant layer 3, wherein the three-dimensional crack-resistant layer 3 is fixed on the upper side of the thermal insulation and sound insulation layer 1.

[0028] Preferably, the thermal insulation and sound insulation layer 1 is bonded to the three-dimensional crack-resistant layer 3. The thermal insulation and sound insulation layer 1 can be made of two types of thermal insulation and sound insulation materials. When using rigid materials, graphite insulation board, polystyrene board, polyurethane board, etc. can be used; when using soft materials, polyurethane rubber pad, EPDM rubber pad, cross-linked polyethylene pad, rubber and plastic pad, etc. can be used.

[0029] Furthermore, the thickness of the thermal insulation and sound insulation layer 1 in this embodiment is also subject to certain limitations. In the preferred embodiment, the thickness of the thermal insulation and sound insulation layer 1 is generally 3mm to 20mm. The reason is that if the thickness of the thermal insulation and sound insulation layer 1 is too small, it will reduce the thermal insulation and sound insulation performance of the system; if the thickness is too large, it will result in material waste and limited space in the building's height.

[0030] In this embodiment, the composite thermal insulation and sound insulation mat is laid on the floor base layer 4. In actual implementation, a protective layer 5 needs to be covered on the composite thermal insulation and sound insulation mat after laying. Preferably, the protective layer 5 can be a self-leveling mortar layer, such as cement-based self-leveling mortar, gypsum-based self-leveling mortar, self-compacting fine aggregate concrete, self-compacting lightweight aggregate concrete, geopolymer, etc., and its compressive strength generally needs to be not less than 15.0 MPa, and its thickness is generally 20mm to 50mm. When the three-dimensional crack-resistant layer 3 of the composite thermal insulation and sound insulation mat in this embodiment is combined with the protective layer 5, it can play a crack-resistant role for the bonding layer 5, thereby improving the construction quality of the floor.

[0031] For the three-dimensional crack-resistant layer 3 in this embodiment, its overall height (or thickness) also has certain requirements. If the thickness of the three-dimensional crack-resistant layer 3 is too low, it will be detrimental to the crack resistance of the protective layer 5; if the thickness of the three-dimensional crack-resistant layer 3 is too high, it will result in material waste and limited space for building height. Therefore, preferably, the overall height of the three-dimensional crack-resistant layer 3 is 10mm to 30mm. Limiting the overall height of the three-dimensional crack-resistant layer 3 to this range can better balance the three aspects of crack resistance effect of the protective layer 5, material waste, and the impact on building height.

[0032] The structure of the three-dimensional crack-resistant layer 3 in this embodiment can be implemented in various ways, as shown in the examples below.

[0033] Combined with appendix Figure 4 One embodiment of the three-dimensional crack-resistant layer 3 is as follows: the three-dimensional crack-resistant layer 3 is a mesh mat 300, which is composed of several interwoven warp and weft threads. The intersections of the warp and weft threads protrude in the direction away from the thermal insulation and sound insulation layer 1, so that the mesh mat 300 has a three-dimensional mesh structure. In this embodiment, the material of the mesh mat 300 can be polyethylene, polyvinyl chloride, glass fiber, etc. Furthermore, in conjunction with the aforementioned embodiment, the thickness of the mesh mat 300 is preferably 10mm to 30mm. In this embodiment, when underfloor heating pipes need to be laid, the underfloor heating pipes are preferably laid under the mesh mat 300.

[0034] Or, in conjunction with the appendix Figure 5The three-dimensional crack-resistant layer 3 can be implemented as follows: the three-dimensional crack-resistant layer 3 includes several continuously laid and interconnected frames 310, with a support frame 311 at the bottom of each frame 310, and the support frame 311 is fixedly connected to the thermal insulation and sound insulation layer 1. Preferably, the frame 310 is polygonal honeycomb-shaped, and the total height of the frame 310 and the support frame 311 is 10mm to 30mm. In this embodiment, the frame 310 and the support frame 311 can be an integrally formed structure, and their material can be polyethylene, polyvinyl chloride, glass fiber, etc.

[0035] Furthermore, in a further improvement based on this implementation, a clip 312 may also be provided on the frame 310, which can be used to fix the underfloor heating pipes when they are laid on the frame 310 within the protective layer 5.

[0036] Or, in combination with the appendix Figure 6 The three-dimensional crack-resistant layer 3 can also be implemented as follows: the three-dimensional crack-resistant layer 3 includes a support 320, ribs 321, and crack-resistant mesh 322; several supports 320 are fixedly disposed on the thermal insulation and sound insulation layer 1, several ribs 321 are interwoven between the supports 320, and the crack-resistant mesh 322 is fixed between the ribs 321, with several mesh holes on the crack-resistant mesh 322. Preferably, the height of the support 320 is 10mm to 30mm, at least one layer of crack-resistant mesh 322 is laid, and the mesh hole diameter of the crack-resistant mesh 322 is 5mm to 20mm. In this embodiment, the crack-resistant mesh 322 can be laid in one or more layers, and the material of the crack-resistant mesh 322 can be metal, glass fiber, etc.; the material of the support 320 can be metal, plastic, etc. The aperture of the crack-resistant mesh 322 is 5mm to 20mm. The reason is that if the aperture is too small, it will not be conducive to the aggregate in the self-leveling mortar forming the protective layer 5 passing through the crack-resistant mesh 322, resulting in insufficient bonding between the protective layer 5 and the three-dimensional crack-resistant layer 3; if the aperture is too large, it will not be conducive to the three-dimensional crack-resistant layer 3 playing a tensile crack-resistant role.

[0037] In summary, to address the technical problems of existing thermal insulation and sound insulation structures, the composite thermal insulation and sound insulation pad of this embodiment is designed with various forms of three-dimensional crack-resistant layers 3, and the three-dimensional crack-resistant layers 3 are fixed on the thermal insulation and sound insulation layer 1 for bonding within the protective layer 5. Through the physical connection, stress dispersion, and energy absorption of the three-dimensional crack-resistant layers 3, the risk of cracking of the protective layer 5 is reduced, and the probability of water seepage, mold growth, and failure of the floor slab thermal insulation and sound insulation system is reduced.

[0038] In other preferred embodiments, in conjunction with the appendix Figure 1 To be continued Figure 3A reflective heat-dissipating layer 2 is fixed between the thermal insulation and soundproof layer 1 and the three-dimensional crack-resistant layer 3. Generally, the reflective heat-dissipating layer 2 is made of aluminum foil. Adhesives can be used to bond the thermal insulation and soundproof layer 1 to the reflective heat-dissipating layer 2, as well as between the reflective heat-dissipating layer 2 and the three-dimensional crack-resistant layer 3. The reflective heat-dissipating layer 2 enhances thermal insulation and soundproofing performance by reflecting heat radiation and sound waves. Specifically, good thermal insulation performance is achieved through the combination of the thermal insulation effect of the insulation material and the reflective heat-dissipating effect of the reflective heat-dissipating layer 2.

[0039] Preferably, the thickness of the reflective heat-equalizing layer 2 is 0.005mm to 0.2mm. Within this thickness range, the thermal insulation and sound insulation performance of the composite thermal insulation and sound insulation pad can be guaranteed, while avoiding material waste and limited space due to excessive thickness.

[0040] Furthermore, in another preferred embodiment, a structural cavity 8 is provided at the bottom of the thermal insulation and sound insulation layer 1. The structural cavity 8 is ultimately located between the lower surface of the thermal insulation and sound insulation layer 1 and the floor base layer 4. This structural cavity 8 design can further enhance the sound insulation performance of the thermal insulation and sound insulation pad. In combination with the aforementioned embodiments, the thermal insulation and sound insulation layer 1, through the combined effect of its own sound insulation material characteristics and the structural cavity 8, as well as the sound reflection performance of the reflective heat-dissipating layer 2, enables the composite thermal insulation and sound insulation pad to possess excellent sound insulation performance.

[0041] Structural cavities 8 exist in various forms, combined with attached... Figure 3 In one embodiment, if the thermal insulation and sound insulation layer 1 is made of a rigid material, multiple grooves can be provided below the thermal insulation and sound insulation layer 1, thereby forming a structural cavity 8 between the grooves and the floor / ground base layer 4. Alternatively, in conjunction with the attached... Figure 1 To be continued Figure 2 In another embodiment, if the thermal insulation and sound insulation layer 1 is made of soft material, multiple hollow sound insulation strips 801 can be provided below the thermal insulation and sound insulation layer 1, relying on the hollow structure of the hollow sound insulation strips 801 themselves as structural cavities 8.

[0042] Example 2

[0043] Combined with appendix Figure 7 To be continued Figure 8 This embodiment proposes a floor insulation and sound insulation system, including a floor base layer 4 and a wall 7 perpendicular to the floor base layer 4. The floor base layer 4 is covered with a plurality of composite insulation and sound insulation pads as described in the technical solution of Embodiment 1, and a vertical sound insulation strip 6 is provided between the composite insulation and sound insulation pads and the wall 7. It also includes a protective layer 5, which is disposed on the upper side of the insulation and sound insulation layer 1, and a three-dimensional crack-resistant layer 3 is incorporated into the protective layer 5.

[0044] In this implementation, gaps will exist between the composite thermal insulation and sound insulation pads continuously laid on the floor base layer 4. These gaps can be filled with elastic sealing materials such as rubber pads or rubber foam, or sealing tape can be pasted between adjacent composite thermal insulation and sound insulation pads. For the gap between the composite thermal insulation and sound insulation pads and the wall 7, this embodiment provides vertical sound insulation strips 6, which can further improve the sound insulation effect.

[0045] The floor insulation and sound insulation system of this embodiment uses a composite insulation and sound insulation pad that combines an insulation and sound insulation layer 1 and a three-dimensional crack-resistant layer 3. It can also be combined with the reflective heat-equalizing layer 2 in embodiment 1. The layers can be tightly connected by bonding.

[0046] Furthermore, in this embodiment, the upper surface of the protective layer 5 is higher than the upper surface of the three-dimensional crack-resistant layer 3, preferably by 5mm to 8mm. This is because if the protective layer 5 is excessively higher than the upper surface of the three-dimensional crack-resistant layer 3, the portion of the three-dimensional crack-resistant layer 3 and the protective layer 5 that is not effectively bonded will increase. Consequently, the physical connection, stress dispersion, and energy absorption functions of the three-dimensional crack-resistant layer 3 will be reduced. Therefore, given a fixed thickness of the three-dimensional crack-resistant layer 3, the protective layer 5 should not be too thick. If a thicker protective layer 5 is required for actual construction, a correspondingly thicker three-dimensional crack-resistant layer 3 should be selected.

[0047] The floor insulation and soundproofing system in this embodiment can be completed by laying and pouring, which greatly simplifies the construction process compared to traditional methods and provides better insulation and soundproofing performance.

[0048] Specifically, the floor insulation and sound insulation system in this embodiment is constructed by laying a composite insulation and sound insulation pad on the floor base layer 4 and then pouring a protective layer 5 with self-leveling mortar (or self-compacting concrete). This method can greatly reduce construction procedures and labor input, and improve construction efficiency. In summary, the floor insulation and sound insulation system in this embodiment has a simple construction procedure and good insulation and sound insulation performance.

[0049] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
