[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a new technical solution: a composite thermal insulation and soundproof floor assembly panel, including a base layer 1, the base layer 1 being made of crack-resistant mortar, and orthogonally distributed glass fiber mesh 12 being laid inside the base layer 1, the glass fiber mesh 12 being bonded and fixed to the base layer 1 by cement mortar.

[0031] Among them, multiple second connecting plates 11 are fixedly connected to the upper surface of the base layer 1, and a functional layer 9 is provided on the upper surface of the base layer 1. The functional layer 9 is a foamed cement composite board or a graphite polystyrene board.

[0032] The outer wall of functional layer 9 is provided with a protective layer 2, which is a cement mortar layer. A corrugated sound insulation felt 10 is embedded inside functional layer 9. The sound insulation felt is 2-3mm thick, with a crest height of 5-8mm, and is spaced 200-300mm apart along the length of the board.

[0033] Furthermore, the lower surface of the functional layer 9 is provided with a plurality of second concave connecting grooves 7, and the upper ends of the plurality of second connecting plates 11 are respectively engaged in the inner wall of the corresponding second concave connecting grooves 7, and the plurality of second concave connecting grooves 7 and the plurality of second connecting plates 11 form a mechanical interlocking structure.

[0034] Furthermore, multiple first connecting plates 8 are fixedly connected to the upper surface of the functional layer 9.

[0035] Furthermore, a protective layer 5 is provided on the upper surface of the functional layer 9. The protective layer 5 is a fiber-reinforced concrete layer with a thickness of 5-8 mm and contains 5%-8% chopped glass fiber.

[0036] Furthermore, the edges of both sides of the protective surface layer 5 and the base layer 1 extend to the outside of the side protective layer 2, forming an overlap of 10-15mm.

[0037] Furthermore, the lower surface of the protective layer 5 is provided with a plurality of first concave connecting grooves 6, and the upper ends of the plurality of first connecting plates 8 are respectively engaged into the inner wall of the corresponding first concave connecting grooves 6.

[0038] Furthermore, four connecting blocks 3 are fixedly connected to the front surface of the assembly plate composed of the base layer 1 and the protective surface layer 5, and four grooves 4 are opened on the rear surface of the assembly plate composed of the base layer 1 and the protective surface layer 5, and sealing strips are provided on the inner walls of the four grooves 4.

[0039] Furthermore, when using this composite thermal insulation and soundproof floor assembly panel, firstly, the fiberglass mesh 12 in the base layer 1 (crack-resistant mortar) is bonded with cement mortar to form a mesh skeleton, which inhibits the cracking of the base layer. At the same time, it forms a mechanical interlock with the second connecting plate 11 and the second concave connecting groove 7 of the functional layer 9, ensuring that the base layer and the functional layer are tightly connected, and avoiding delamination caused by thermal expansion and contraction of materials.

[0040] Among them, the foamed cement composite board or graphite polystyrene board of functional layer 9 provides high-efficiency thermal insulation performance. The corrugated sound insulation felt 10 embedded inside increases the sound wave reflection path through the undulating structure. The 2-3mm thick sound insulation felt with a 5-8mm wave peak height can effectively absorb mid-to-high frequency noise of 125-4000Hz. The corrugated design with a 200-300mm interval makes the sound insulation felt form a continuous sound barrier in the functional layer, reducing solid-borne sound transmission between floors.

[0042] The protective surface layer 5 (fiber-reinforced concrete layer) is connected to the first concave connecting groove 6 of the functional layer 9 via the first connecting plate 8. The 5-8mm thick concrete layer contains 5%-8% chopped glass fiber to improve surface wear resistance and impact resistance. At the same time, the 10-15mm overlap covers the side protective layer 2, forming a complete thermal bridge blocking structure to prevent heat loss at the edges. In terms of load transfer, the base layer 1 and the protective surface layer 5 form a "sandwich" type force-bearing system through the upper and lower connecting plates. The second connecting plate 11 and the first connecting plate 8 respectively bear the shear force and tensile force, ensuring that the overall stress of the assembled plate is uniform.

[0043] Among them, the flexible material of the corrugated sound insulation felt 10 can buffer floor vibration and reduce structural sound transmission. Combined with the porous structure of foamed cement, it can achieve a dual performance improvement of thermal insulation (thermal conductivity ≤0.06W / (m·K)) and sound insulation (weighted sound insulation ≥35dB).

[0044] During construction, the assembly panel can be quickly spliced ​​together with the groove 4 through the connecting block 3, eliminating the need for on-site wet work and improving installation efficiency;

[0045] Among them, the design of the sealing strip and the overlapping edge simplifies the node processing process and reduces the impact of construction errors on performance;

[0046] The overall structure meets the requirements of building energy conservation and sound insulation standards, and is suitable for floor partitioning in residential buildings, office buildings and other buildings. It is especially suitable for the rapid assembly needs of prefabricated buildings. Through material composite and structural optimization, it realizes the integrated functions of heat preservation, sound insulation and structure, and improves the comfort of building use and construction efficiency.

[0047] Structural Description:

[0048] Base layer 1: The bottom support structure of the assembly panel is made of crack-resistant mortar (compressive strength ≥30MPa). Inside, glass fiber mesh cloth 12 (grid spacing 5mm×5mm) is laid orthogonally. It is bonded with cement mortar to form a mesh skeleton, which inhibits the cracking of the base layer (crack width ≤0.1mm) and provides an installation base surface for functional layer 9.

An embedded corrugated sound insulation felt 10, together with the upper and lower connecting plates, forms a "thermal insulation-sound insulation" composite system.

[0051] Wave-shaped sound insulation felt 10: Embedded inside the functional layer 9, with a thickness of 2-3mm and a wave crest height of 5-8mm, set at intervals of 200-300mm along the length of the board. The undulating structure increases the sound wave reflection path (reflection times ≥3 times), effectively absorbing mid-to-high frequency noise of 125-4000Hz (sound absorption coefficient ≥0.8), and reducing solid-borne sound transmission between floors (weighted sound insulation ≥35dB).

[0054] The second concave connecting groove 7 is opened on the lower surface of the functional layer 9, with a depth of 10mm. It cooperates with the second connecting plate 11 to form a mortise and tenon structure. The grooves are evenly distributed at a spacing of 200mm to ensure the connection strength between the base layer and the functional layer (tensile bond strength ≥0.3MPa) and adapt to the vibration load of prefabricated buildings.

[0055] First connecting plate 8: Fixed to the upper surface of functional layer 9, with the same material as the second connecting plate, and the upper end is snapped into the first concave connecting groove 6 of protective surface layer 5, bearing the tensile force between functional layer and protective surface layer (tensile strength ≥10kN / m), forming a "sandwich" type force system to ensure uniform load transfer.

[0056] First concave connecting groove 6: Formed on the lower surface of protective layer 5, 8mm deep, mates with first connecting plate 8, with the same spacing as second connecting plate, enhancing the connection reliability between protective layer and functional layer (pull-out resistance ≥8kN / m). 2 This prevents the surface layer from peeling off.

[0057] Protective Surface Layer 5: Surface load-bearing structure, made of fiber-reinforced concrete (5-8mm thick), with 5%-8% chopped glass fiber (6-12mm in length) added, compressive strength ≥25MPa, wear resistance improved by 30%, effectively resisting daily loads and impacts (such as furniture placement and people walking).

[0058] Connecting block 3: Fixed to the front surface of the assembly panel, made of the same material as the base layer, with a cross-sectional size of 20mm×20mm, it is inserted into the groove 4 of the adjacent panel to form a mechanical connection (insertion depth ≥15mm), supports rapid splicing (single block installation time ≤2 minutes), and is suitable for dry construction of prefabricated buildings.

[0059] Groove 4: Located on the rear surface of the assembly plate, with a sealing strip (EPDM material, Shore A60 hardness) pasted on the inner wall. It cooperates with the connecting block 3 of the adjacent plate to form an elastic seal (sealing pressure ≥5kPa), blocking the transmission of airborne and solid-borne sound (sound leakage ≤1.5m). 3 / (m 2 ·h)) to prevent moisture from seeping in.
