Description

Technical Field

[0001] This utility model relates to the field of basement floor slab technology, specifically to an ultra-deep multi-story basement floor slab structure. Background Technology

[0002] Basement floors are floor structures located below ground level in a building. Basement floors serve to divide spaces and require consideration of various factors, including moisture-proofing and waterproofing. The design and construction of basement floors also have strict requirements based on different functional needs and building codes. In multi-story basements, precast floor slabs have gradually replaced cast-in-place floor slabs because they are easier to transport and assemble and have lower costs. When assembling existing basement floor slabs, most of them are simply two rectangular floor slabs placed directly on a load-bearing wall, and then the gap between the two floor slabs is filled with cement. However, this method of splicing floor slabs makes the lateral stability between the floor slabs insufficient, making them prone to displacement. In addition, the assembly of floor slabs is slow and inefficient. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:

[0016] like Figure 1 , Figure 2 As shown, this utility model provides a floor slab structure for an ultra-deep multi-story basement, including a first floor slab 1 and a second floor slab 2. Both the first floor slab 1 and the second floor slab 2 are provided with lifting grooves 3. A crossbeam 4 is provided at the bottom of the second floor slab 2. A first protruding plate 5 is fixed to the side of the first floor slab 1, and a second protruding plate 9 is fixed to the side of the second floor slab 2. The first floor slab 1 and the first protruding plate 5, as well as the second floor slab 2 and the second protruding plate 9, form the floor slab body 121. A moisture-proof layer 122 and a waterproof layer 123 are provided on the floor slab body 121. A stepped groove 6 is formed on the side of the first protruding plate 5. A connecting block 7 is fixed to the bottom of the first protruding plate 5. The gap between the connecting blocks 7 forms a connecting groove 8. A stepped groove 10 is formed on the side of the second protruding plate 9. A connecting block 11 is fixed to the upper part of the second protruding plate 9. The gap between the connecting blocks 11 forms a connecting groove 12. Threaded sleeves 13 are fixed to both the first stepped groove 6 and the second stepped groove 10. Bolts are threadedly connected to the threaded sleeves 13. 14. A T-shaped groove 15 is formed between the first stepped groove 6 and the second stepped groove 10. A T-shaped plate 16 is provided inside the T-shaped groove 15. By placing the first protruding plate 5 on the second protruding plate 9, the first connecting block 7 and the second connecting block 11 can be interlocked, so that the first protruding plate 5 can be connected to the second protruding plate 9. This allows the first floor slab 1 and the second floor slab 2 to be quickly connected. Therefore, the first floor slab 1 and the second floor slab 2 can be quickly assembled and positioned, improving assembly efficiency.

[0017] Furthermore, floor slab 1, convex plate 5, and connecting block 7 are prefabricated as a whole using a mold, as are floor slab 2, convex plate 9, and connecting block 11. Floor slab 1, convex plate 5, and connecting block 7 form a single integrated structure, and floor slab 2, convex plate 9, and connecting block 11 form a single integrated structure, in order to improve the strength of the floor slabs during use.

[0018] Furthermore, the first connecting block 7 is adapted to the second connecting groove 12, and the second connecting block 11 is adapted to the first connecting groove 8. By connecting the first connecting block 7 to the second connecting groove 12 and connecting the second connecting block 11 to the first connecting groove 8, the first convex plate 5 and the second convex plate 9 can be quickly connected.

[0019] Furthermore, multiple No. 1 connecting blocks 7 and No. 2 connecting blocks 11 are provided, and the No. 1 connecting blocks 7 and No. 2 connecting blocks 11 are staggered, so that the multiple No. 1 connecting blocks 7 and No. 2 connecting blocks 11 can interlock with each other and form a stable connection. Example 2:

[0020] like Figure 3 , Figure 4 and Figure 5 As shown, based on Embodiment 1, by setting the No. 1 connecting block 7 and the No. 2 connecting block 11, the connection points of the No. 1 floor slab 1 and the No. 2 floor slab 2 can be interlocked, so that the No. 1 floor slab 1 and the No. 2 floor slab 2 can be stably assembled and connected.

[0021] Furthermore, the first stepped groove 6 and the second stepped groove 10 form a T-shaped groove 15, and the T-shaped plate 16 is located inside the T-shaped groove 15. By placing the T-shaped plate 16 inside the T-shaped groove 15 formed by the first stepped groove 6 and the second stepped groove 10, and by using bolts 14, the T-shaped plate 16 can be connected and fixed to the first floor slab 1 and the second floor slab 2 respectively. Therefore, the first floor slab 1 and the second floor slab 2 can be fixedly connected, improving the stability of the connection between the first floor slab 1 and the second floor slab 2.

[0022] Furthermore, bolt 14 passes through T-shaped plate 16 and is threadedly connected to threaded sleeve 13, which facilitates the fixed connection of T-shaped plate 16 to floor slab 1 and floor slab 2 respectively, and can further limit the movement between floor slab 1 and floor slab 2.

[0023] Furthermore, a moisture-proof layer 122 is installed on the main floor slab 121, and a waterproof layer 123 is installed on the moisture-proof layer 122. The main floor slab 1, the first convex plate 5, and the first connecting block 7 form the main floor slab 121. The second floor slab 2, the second convex plate 9, and the second connecting block 11 also form the main floor slab 121. The moisture-proof layer 122 is a reactive inorganic floor moisture-proof product composed entirely of inorganic materials and dissolved in water, formulated with a patented compound. It penetrates deep into the cement, and over time, the gel particles increase in number and size, blocking the capillary gaps within the cement and forming a dense 20-30mm moisture-proof coating. When exposed to moisture, the elastic gel particles expand, adapting to the shape of the gaps and effectively preventing moisture from passing through. The waterproof layer 123 is a mortar formulated with cement and sodium silicate as base materials, which can be used for leak sealing and waterproofing in underground engineering. Cement-based penetrating crystalline waterproofing materials are also a common choice, improving the density of the floor slab and enhancing its impermeability.

[0024] The working principle of this utility model is as follows: During use, the lifting slot 3 allows for the separate hoisting of floor slab 1 and floor slab 2. When assembling floor slab 1 and floor slab 2 in the basement, the crossbeam 4 is first placed on the load-bearing wall of the basement, and then floor slab 1 is placed on floor slab 2. At this time, the first protruding plate 5 and the second protruding plate 9 engage, allowing the first connecting block 7 to insert into the second connecting slot 12, and the second connecting block 11 to insert into the first connecting slot 8. Therefore, while quickly assembling floor slab 1 and floor slab 2, the system can also limit the movement of floor slab 1 and floor slab 2, improving the stability of the assembled floor slab 1 and floor slab 2. Qualitatively, after the No. 1 floor slab 1 and the No. 2 floor slab 2 are positioned and assembled, the T-shaped plate 16 is placed in the T-shaped groove 15 formed by the No. 1 step groove 6 and the No. 2 step groove 10. The T-shaped plate 16 can be fixed at the connection between the No. 1 convex plate 5 and the No. 2 convex plate 9 by bolts 14. Thus, the No. 1 floor slab 1 and the No. 2 floor slab 2 can be fixedly connected by the T-shaped plate 16. The T-shaped plate 16 can also seal the connection between the No. 1 convex plate 5 and the No. 2 convex plate 9, thereby sealing the connection between the No. 1 floor slab 1 and the No. 2 floor slab 2, preventing water leakage and seepage at the connection between the No. 1 floor slab 1 and the No. 2 floor slab 2, and improving the safety of the basement floor slab during use.
