[0045] Embodiment:

[0046] As Figures 1-7 shown, the embodiment of the present application discloses a free-form prefabricated slab, which is designed by connecting the slabs and the connecting members between the slabs to facilitate the assembly of the subsequent slabs.

[0047] The specific structure of the free-form prefabricated slab in the present application includes:

[0048] A plurality of concrete structure plates 1 are connected by connecting units to form a whole by splicing;

[0049] A plurality of anti-collision components 2 are installed around the concrete structure plate 1 to form a protective layer to prevent the structure plate from being damaged by impact;

[0050] A connecting unit 3 is connected to any one of the concrete structure plates 1 at one end and connected to the adjacent concrete structure plate 1 at the other end, which is convenient for realizing the stability of the concrete structure plate 1 during splicing;

[0051] As Figure 2 , 3 shown, the connecting unit 3 includes:

[0052] A pre-embedded part 301 is arranged inside the concrete structure plate 1, which cooperates with the subsequent connecting member 302 to complete the splicing of the structure plate;

[0053] The connecting component 302 is sleeved on the embedded part 301, and this method is conducive to the overall assembly.

[0054] To better achieve the connection between the concrete structural slabs 1, the embedded part 301 described in this application includes:

[0055] An embedded connecting plate 303 is set inside the concrete structure slab 1. The embedded connecting plate 303 facilitates the subsequent assembly of the corresponding steel bars and also helps to ensure the stability of the concrete structure slab.

[0056] Multiple anchoring steel bars 304 are spaced apart on the pre-embedded connecting plate 303 and are welded to the pre-embedded connecting plate 303, which can ensure the strength and stability of the concrete structure slab 1.

[0057] An embedded seat 305 is disposed on the embedded connecting plate 303, and the top of the embedded seat 305 extends upward beyond the concrete structure plate 1. The portion of the embedded seat 305 extending beyond the concrete structure plate 1 is provided with threads. The embedded seat 305 serves as a subsequent connection support point.

[0058] Sleeve 306 is disposed on the top of the pre-embedded base 305. Sleeve 306 serves as a locking part. After the subsequent connecting member 307 is connected and fixed to the pre-embedded base 305, locking is completed through sleeve 306.

[0059] like Figure 4 As shown, the connecting member 307 includes:

[0060] At least two lifting rings 307 are fitted onto the top of the pre-embedded seat 305, and the lifting rings 307 are located below the sleeve 306. The lifting rings 307 are directly fitted onto the pre-embedded seat 305, and then lock together by cooperating with the bottom of the sleeve 306.

[0061] Chain 308 is disposed between the lifting rings 307. Chain 308 can improve the splicing strength of concrete structural slab 1 and ensure stability.

[0062] Further explanation of the structure of the lifting ring 307: the connection between the lifting ring 307 and the chain 308 is achieved by locking bolt 309, that is, the connection is completed by locking bolt 309 to ensure stability.

[0063] In order to match the assembly of the embedded seat 305 and the subsequent hanging ring 307, the embedded seat 305 is designed, specifically, the embedded seat 305 is divided into an embedded section 310 and a matching section 311, the matching section 311 is located at the top of the embedded section 310, that is, the embedded section 310 is in the interior of the concrete structure plate 1 for stability, and the matching section 311 is protruding from the concrete structure plate 1 and is provided with threads for threaded connection with the sleeve 306.

[0064] The cross-sectional diameter of the embedded section 310 is greater than that of the matching section 311, and the diameter of the embedded section 310 in the application is larger, which can support the chain 308 and ensure the stability of the connecting unit 3 after use.

[0065] The concrete structure plate 1 in the application can be provided with four connecting units 3 during use, which are respectively located at the four corners, so as to stably connect the concrete structure plates 1 in each direction.

[0066] Specifically, the anti-collision assembly 2 in the application includes an anti-collision edge 201 located at the side edge of the concrete structure plate 1, which can ensure the stability of the overall concrete structure.

[0069] A two-way reinforcement method is used for design. The poured concrete is C30, and the steel bar is HRB400:

[0070]

[0071] A S =234mm 2 , the cross-sectional size is known as 1000*300, according to the short side configuration requirement of the plate structure design specification HRB400 diameter 12mm@150mm, and the distribution steel bar is HRB400 diameter 12mm@200mm; the specific basis is that the plate length is 4m, the plate width is 1.5m, and the plate thickness is 0.3m, the plate is a one-way simply supported plate, and 1m plate is taken for research, the design load is 45kN / m. Considering 1.5 times of dynamic coefficient, M=1.5ql 2 / 8, M=18.98kN.m. Under the action of heavy truck cyclic load, the bottom of the plate may appear concave-convex phenomenon.

[0072] S2: According to the design drawing, the peripheral frame U-shaped section steel (50*300*10) is lofted, and the position of the internal steel bars which need to be clamped and bundled is lofted.

[0073] S3: After the blanking is completed, the plastic buckle is bonded on the U-shaped section steel, the horizontal steel bars are clamped into the buckle, and the vertical distribution steel bars are bound on the horizontal steel bars, so as to form a steel bar frame, which is convenient for construction and saves labor cost, as shown in Figure 6 、 7

[0074] S4: When the concrete is cast on site, the excess amount is poured, and a layer of plastic film is laid at the bottom of the frame before pouring to prevent the concrete from overflowing from the bottom. During the concrete pouring process, good vibrating work should be done to ensure that each slab is vibrated and compacted to form a concrete structure plate.

[0075] S5: Install the connecting unit between the concrete structure plates, wherein the connecting unit is designed with reference to the structure in the drawing.

Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples. In addition, the skilled in the art can combine and combine the different embodiments or features of the embodiments or examples described in the specification without contradiction.
