[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Refer to Figure 1 , Figure 5 , an embodiment provided by the present invention:

[0025] A new type of seamless basement concrete floor slab includes a concrete floor slab layer 1 and two support members 2. Grooves 3 are provided on both sides of the two support members 2. Slots 6 are provided on the upper and lower sides between the inner walls of two groups of two opposite grooves 3. A grouting pipe 4 is embedded in the middle of the two support members 2. Grout outlet pipes 5 are fixedly provided around the two grouting pipes 4. The four grout outlet pipes 5 on the upper and lower sides respectively penetrate into the four slots 6, and the four grout outlet pipes 5 on both sides respectively penetrate into the four grooves 3. A protective layer 7 is fixedly provided on the upper end of the concrete floor slab layer 1, and the support member 2 is provided in an L-shaped structure.

[0026] Specifically, by providing the groove 3, when the concrete floor slab layer 1 is installed on the support member 2, the support member 2 and the concrete floor slab layer 1 can be connected by filling concrete into it, making the connection between the two closer. By providing the grouting pipe 4, concrete can be filled into it through the grouting pipe 4 when the concrete floor slab layer 1 is installed on the support member 2. By providing the grout outlet pipe 5, the concrete inside the grouting pipe 4 can be introduced into the slots 6 and the grooves 3 to fill the inside of the grooves 3 and the slots 6. By providing the protective layer 7, the service life of the concrete can be extended, and the overall performance of the basement can be improved, which can significantly improve the durability, comfort and safety of the structure. The concrete floor slab layer 1 and the injected concrete slurry are both added with waterproofing agents to improve the waterproof performance of the floor slab.

[0027] Refer to Figures 2 - 5, the concrete floor layer 1 includes a first concrete slab 101 and a second concrete slab 102. A plurality of steel bars 103 are fixedly embedded inside the first concrete slab 101 and the second concrete slab 102. A connecting grid 104 is fixedly arranged between the first concrete and the second concrete. Both ends of the plurality of steel bars 103 respectively penetrate into a plurality of slots 6;

[0028] Specifically, by setting the first concrete slab 101 and the second concrete slab 102, the strength of the concrete floor layer 1 can be improved. And a plurality of steel bars 103 are arranged inside the first concrete slab 101 and the second concrete slab 102. The steel bars 103 have excellent tensile properties. Embedding them in the concrete can significantly improve the tensile strength of the floor slab, enabling it to bear greater loads. The steel bars 103 can help the concrete floor share the load more evenly, reduce local stress concentration, and thus improve the stability of the overall structure. The steel bars 103 can effectively control the concrete cracks caused by temperature changes, humidity fluctuations or load changes. The arrangement of the steel bars 103 can prevent the excessive expansion of cracks and maintain the integrity of the structure. By setting the connecting grid 104 between the first concrete slab 101 and the second concrete slab 102, the connecting grid 104 can effectively connect the two independent concrete floor layers 1 into a whole, thereby enhancing the stability of the overall structure. This connection method can ensure that the floor slabs can work together when stressed, reducing relative displacement and deformation.

[0029] Refer to Figure 6 , the protective layer 7 includes a sound insulation layer 701. An insulation layer 702 is fixedly arranged at the upper end of the sound insulation layer 701. A waterproof layer 703 is fixedly arranged at the upper end of the insulation layer 702. The sound insulation layer 701 is set as a rubber coating. The insulation layer 702 is set as a ceramic heat insulation coating. The waterproof layer 703 is set as an acrylic coating;

[0030] Specifically, by setting the sound insulation layer 701 to reduce noise transmission and improve acoustic comfort. The rubber coating contains elastic materials, which can effectively isolate noise, has good sound insulation effect, and is wear-resistant and durable. By setting the insulation layer 702, the heat exchange between the floor slab and the ground can be effectively isolated. This ceramic heat insulation coating contains tiny ceramic beads, which can effectively reflect heat and reduce heat transfer. By setting the waterproof layer 703, the waterproof ability is enhanced. The waterproof layer 703 can prevent the concrete floor from getting wet due to water penetration, reduce the risk of mildew and decay, and keep the indoor environment dry and comfortable.

[0031] When constructing the basement concrete floor slab, the following aspects need to be noted: Concrete mix ratio: Select a suitable concrete mix ratio to ensure the strength and durability of the floor slab; Construction technology: Ensure that the vibration, leveling, and curing work during construction are in place to avoid the occurrence of hollowing or cracking; Waterproof treatment: Conduct sufficient waterproof treatment on the basement floor slab to improve its moisture-proof effect.

[0032] Working principle: When in use, this structure installs the concrete floor slab layer 1 between two support members 2, inserts the steel bars 103 into the slots 6, and then injects concrete into the interior through the grouting pipe 4. The concrete enters the grooves 3 and the interior of the slots 6 through the slurry outlet pipe 5 for filling, so that a tight connection is formed between the concrete floor slab layer 1 and the support members 2;

[0033] Secondly, a protective layer 7 is provided on the upper side of the concrete floor slab layer 1 to protect the concrete floor slab layer 1. The protective layer 7 can improve the heat insulation, sound insulation, and waterproof effects of the concrete floor slab layer 1 through the sound insulation layer 701, the heat insulation layer 702, and the waterproof layer 703, thereby extending the service life of this concrete floor slab.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
