The rib frame includes two parallel main ribs and two end ribs transversely connected between the two main ribs. The expanded aggregate core material is disposed within the rib frame and laid between the main ribs and the end ribs. The wear-resistant concrete surface layer is laid on the expanded aggregate core material. Multiple limiting members are respectively disposed on the two main ribs and the two end ribs and surround the periphery of the wear-resistant concrete surface layer. The ends of the limiting members opposite to the expanded aggregate core material are flush with the end faces of the wear-resistant concrete surface layer opposite to the expanded aggregate core material.

[0007] In some embodiments, the number of limiting members is 4, with each of the 4 limiting members corresponding to one of the two main ribs and two end ribs, and the limiting members are fixedly installed on the corresponding main ribs or end ribs.

[0008] In some embodiments, both the main rib and the end rib have inverted portions at opposite ends of a length side. The length direction of the inverted portions is the same as that of the main rib or the end rib, and the two inverted portions at opposite ends of the length side form a notch.

[0009] In some embodiments, the expanded stone core material is inserted through the notch, the expanded stone core material is filled in the main rib and the end rib, and the inverted part is disposed in the expanded stone core material.

[0026] Please refer to Figures 1 to 5 This embodiment discloses a floor slab assembly, which includes a rib 100, a expanded stone core material 200, a limiting member 300, and a wear-resistant concrete surface layer 400.

[0027] Please refer to Figure 1 and Figure 2 The rib 100 includes a main rib 110 and end ribs 120. In some embodiments, reinforcing ribs 130 are added to strengthen the structure, and additional ribs such as... are also embedded. Figure 2 The wire mesh structure shown in the figure has two main ribs 110 that are parallel and spaced apart, two end ribs 120 that are laterally connected between the two main ribs 110, and reinforcing ribs 130 that are laterally connected between the two main ribs 110. The wire mesh is laid between the main ribs 110 and the end ribs 120.

[0028] Please refer to Figure 4 and Figure 5, Figure 4 The image shows expanded stone core material 200 laid between two main ribs 110. Figure 5 The diagram shows that the expanded stone core material 200 is disposed within the rib frame 100 and is laid between the two end ribs 120. Based on the structural features of the rib frame 100 described above, it can be seen that the expanded stone core material 200 is laid between the main rib 110 and the end ribs 120.

[0029] Figure 3 The relative positional relationship between the limiting member 300 and the main rib 110 is shown. In some embodiments, the limiting member 300 has an L-shaped cross-section, so that the limiting member 300 includes a transverse portion and a vertical portion connected to the transverse portion. The transverse portion is connected to the main rib or end rib by a surface connection. The end of the vertical portion away from the transverse portion is flush with the end face of the wear-resistant concrete surface layer 400 away from the expanded stone core material 200.

[0030] In some implementation methods, please refer to Figure 3 In the embodiment where angle steel is used as the limiting member 300, the limiting member 300 connected to the main rib 110 is welded to the top side of the main rib 110, and the limiting member 300 connected to the end rib 120 is welded to the top side of the end rib 120. The limiting member 300 connected to the main rib 110 and the limiting member 300 connected to the end rib 120 are in close contact at adjacent locations.

[0031] Please refer to the reference. Figure 1 , Figure 3 , Figure 4 and Figure 5 Four limiting members 300 are provided opposite to each other. The four limiting members 300 are respectively connected to two main ribs 110 and two end ribs 120, and are distributed along the length direction of the corresponding main ribs 110 or end ribs 120. The limiting members 300 connected to the main ribs 110 are distributed along the length direction of the main ribs 110, and the limiting members 300 connected to the end ribs 120 are distributed along the length direction of the end ribs 120. All four limiting members 300 are located on the same side of the thickness of the expanded stone core material 200. The wear-resistant concrete surface layer 400 is laid between the four limiting members 300 and is flush with the limiting members 300. The wear-resistant concrete surface layer 400 is formed by pouring wear-resistant concrete.

[0032] This solution uses a prefabrication method to produce the floor slab components. The wear-resistant concrete surface layer 400 is flush with the limiting component 300, which limits the pouring range of the wear-resistant concrete surface layer 400. The wear-resistant concrete surface layer 400 is formed by pouring wear-resistant concrete and is laid between the four limiting components 300. By controlling the wear-resistant concrete surface layer 400 to be flush with the limiting component 300, all floor slab components can be kept on the same plane after installation, thus avoiding the concrete pouring and hardening time during on-site construction.

[0033] This solution uses expanded stone core material 200 laid between the main rib 110 and the end rib 120, which makes the floor slab assembly lightweight. The thickness of the wear-resistant concrete surface layer 400 can be controlled by four limiting members 300. The surface of the wear-resistant concrete surface layer 400 is the road surface of the vehicle passage. The wear-resistant concrete surface layer 400 has excellent wear resistance and can maintain the long-term use of the floor slab assembly.

[0034] This solution prefabricates the floor slab components required for this application, enabling rapid on-site installation. The construction is completed using mechanized assembly methods, greatly reducing the difficulty of on-site installation, minimizing the impact of on-site construction on the surrounding area, accelerating the construction speed, improving construction accuracy, and reducing the amount of manual labor required.

[0035] In some embodiments, both the main rib 110 and the end rib 120 are provided with inverted portions at opposite ends of a length side. The length direction of the inverted portions is the same as the length direction of the main rib 110 or the end rib 120, and the two inverted portions at opposite ends of the length side form a notch.

[0036] In some embodiments, the expanded stone core material 200 passes through the gaps in the main rib 110 and the end rib 120, the expanded stone core material 200 fills the main rib 110 and the end rib 120, and the inverted part is provided inside the expanded stone core material 200. The inverted part strengthens the connection between the rib frame 100 and the expanded stone core material 200.

[0037] As mentioned above, the reinforcing rib 130 of the rib 100 is connected between the two main ribs 110. In some embodiments, the reinforcing rib 130 is connected to the midpoint of the main rib 110 in the longitudinal direction, so that the main rib 110 is subjected to force balance in the longitudinal direction.

[0038] In the thickness direction of the expanded silica core material 200, the main ribs 110 and end ribs 120 of the rib frame 100 have the same distribution range. In some embodiments, such as Figure 5 As shown, in the thickness direction of the expanded stone core material 200, the reinforcing rib 130 is provided within the distribution range of the end rib 120, the top end of the reinforcing rib 130 is lower than the top end of the end rib 120, and the bottom end of the reinforcing rib 130 is higher than the bottom end of the end rib 120.

[0039] Based on the requirements of parking lots for the road surface of vehicle walking lanes, and the inventor's specific implementation experience in the project, the inventor provides some application parameters for this solution, which are detailed below.

[0040] Figure 6The diagram illustrates the relative positional relationship between two adjacent floor slab assemblies during on-site installation. It is necessary to control the gap between the two floor slab assemblies to be within a small range. Therefore, in some embodiments, the vertical distance between the limiting member 300 and the outer side of the main rib 110 is 5mm ± 1mm. When the distance between the main ribs 110 of two adjacent floor slab assemblies is 'a', if the vertical distance between the limiting member 300 and the outer side of the main rib 110 is 5mm, then the spacing between the wear-resistant concrete surface layer 400 of the two adjacent floor slab assemblies is 'a+10mm'.

[0041] In some implementations, the thickness of the wear-resistant concrete surface layer 400 is 20mm ± 2mm, which is sufficient for safe vehicle movement.

[0042] In some implementations, the wear-resistant concrete is C30 wear-resistant fine aggregate concrete. C30 represents the standard value of the compressive strength of wear-resistant concrete as 30 MPa. Fine aggregate concrete has a smaller aggregate particle size, stronger interfacial bonding, and is easier to fill gaps.

[0043] In some embodiments, the main ribs 110 and end ribs 120 of the floor slab are made of Q235 steel. Q235 steel is a carbon structural steel that has high strength, good plasticity and toughness, and good weldability, which is beneficial for the welding and installation of the limiting component 300.

[0044] In some embodiments, the thickness of the expanded stone core material is 80mm ± 8mm, which is sufficient for safe vehicle movement. Combined with the wear-resistant concrete surface layer having a thickness of 20mm ± 2mm, the thickness of the floor slab assembly in this embodiment is controlled to be around 100mm.

[0045] In some implementations, the density of the expanded stone core material 200 is grade 400, and grade 400 expanded stone core material belongs to lightweight aggregate foamed concrete composite material.

[0046] This embodiment also discloses a self-propelled multi-level parking facility, whose vehicle passage is formed by laying multiple of the above-mentioned floor slab components. Please refer to... Figure 6 The gaps between two adjacent floor slab components are filled with flexible sealant 500. Flexible sealant 500 can be a type of cement-based sealant, which has the advantages of low cost, simple construction and good weather resistance.

[0047] By using the aforementioned floor slab components to provide the road surface for vehicle traffic, this self-propelled multi-level parking facility reduces the impact of on-site construction on the surrounding area, speeds up construction, improves construction accuracy, and reduces the amount of manual labor required.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
