[0036] Note that, in the case of use, further, preferably, further and more preferably are simple beginnings for explaining another embodiment based on the previous embodiment, and the content of further, preferably, further or more preferably followed by the above embodiment is combined with the previous embodiment as a complete composition of another embodiment. Several further, preferably, further or more preferably settings followed by the same embodiment can be arbitrarily combined to form another embodiment.

[0037] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the accompanying drawings and specific embodiments are only exemplary and should not be construed as limiting the scope of protection of the present invention.

[0038] Embodiment 1:

[0039] Please refer to Figures 1 to 9 This embodiment records an assembled non-disassembly formwork system, which at least includes a steel cage 1, a casting formwork 2 and a fixed hanger 3. Among them, the fixed hanger 3 is arranged on the casting formwork 2, and the casting formwork 2 is hung on the steel cage 1 through the fixed hanger 3. Compared with the traditional formwork, the casting formwork 2 can be hung on the steel cage 1, and the fixed hanger 3 separates the steel cage 1 and the casting formwork 2 to form a steel cage protection layer. After the formwork is completed, pouring can form a prefabricated concrete component, which can be cast on site or prefabricated in a factory.

[0040] Further, please combine Figure 2 , Figure 5 and Figure 6 , beams, columns or other concrete structures generally include a steel structure and a casting structure. In this embodiment, the steel cage 1 is a steel structure, and the casting structure is concrete. The steel cage 1 includes at least longitudinal bars 11 and stirrups 12. The best way of this embodiment is to hang the casting template 2 on the stirrups 12. However, it should be noted that steel bars can also be separately arranged on the steel cage 1 to cooperate with the hanging of the casting template 2, which is not considered as a limitation.

[0041] In order to further stabilize the casting formwork 2 , in a preferred implementation manner of the present embodiment, the stirrups 12 are configured as threaded bars or patterned bars, which can effectively prevent the fixed hangers 3 of the casting formwork 2 from sliding on the stirrups 12 .

[0042] As another preferred implementation manner of this embodiment, the fixed hangers 3 can be arranged in two rows or more along the height direction of the casting template 2. The upper and lower rows of hangers can restrain each other, which can better prevent the mold from expanding in the out-of-plane direction during concrete pouring.

[0043] As another preferred implementation of this embodiment, only one casting template 2 is provided for each casting surface of the prefabricated component in this embodiment. Taking a structural column or a structural beam as an example, it is formed by enclosing four casting templates 2. However, the creative coordination of the structural casting template 2 and the fixed hanger 3 of this embodiment, such as when a casting surface has a large span, can be formed by combining multiple casting templates 2 side by side. In this way, the casting templates 2 can be produced according to uniform sizes. For example, a beam width of 30 cm can be achieved by two 15 cm wide casting templates 2 side by side, and a beam width of 45 cm can be achieved by three 15 cm wide casting templates 2 side by side. Therefore, the utility model only needs to prefabricate a casting template 2 of the basic size to achieve the casting needs of various prefabricated components such as beams and columns through combination.

[0044] Please combine Figure 3 , Figure 4 and Figure 8For the sake of economy and convenience, the fixed hanger 3 includes two hook pieces 31 and a connecting piece 32, wherein the connecting piece 32 is connected between the two hook pieces 31. The casting template 2 is provided with two strip holes 311 for the two hook pieces 31 to pass through. The two hook pieces 31 are correspondingly passed through the two strip holes 311 and then hung on the steel cage 1, and the connecting piece 32 is close to the outside of the casting template 2. The hook piece 31 can prevent slurry leakage well by being arranged in a sheet shape and cooperating with the strip holes 311, and the cost is more economical. This embodiment is a preferred choice of the first embodiment of the present invention, and it does not necessarily constitute the only embodiment of the present invention. For example, a hook installed on the casting template 2 can also meet the basic requirements for the implementation of this solution.

[0045] Please combine Figure 2 , Figure 5 , Figure 8 and Fig. 9 In order to further improve the stability of the casting formwork 2, the assembled non-disassembly formwork system also includes a positioning fixture 4, which includes a first fixing unit 41 and a first positioning unit 42. The first fixing unit 41 is fixed to the steel cage 1, and the first positioning unit 42 positions and installs the casting formwork 2 on the first fixing unit 41. The casting formwork 2 is positioned and fixed on the first fixing unit 41 by the first positioning unit 42 to further stably install the casting formwork 2. The number of positioning fixtures 4 is not necessarily limited in this embodiment. The positioning fixture 4 has the following structural forms, which are only given as limited examples in this embodiment and do not necessarily constitute the only implementation method of this embodiment:
