[0100] It should be noted that the "pulling rod 21 is partially or entirely provided with threads" is interpreted as that the first positioning member 22 on the pulling rod 21 is adjusted in position by threads, but in actual operation, the adjustment range does not need to reach the full length, so the thread arrangement can be realized within the adjustment range, but in actual component preparation, the threads can also be arranged throughout the length. Preferably, the first positioning member 22 is a nut or a T-shaped nut.

[0101] In order to facilitate the thickness positioning of the first pouring space 31 and the second pouring space 32 when pouring the concrete layer, and also facilitate the formwork requirement, each positioning and pulling member 2 further at least includes two second positioning members 23. The two second positioning members 23 are respectively arranged at the two ends of the pulling rod 21, and the outer ends of the second positioning members 23 at the two ends of the plurality of pulling rods 21 are flush.

Because the adjustment method is screw adjustment, the adjustment precision and convenience are high, and it is also relatively convenient.

[0104] S4: Pouring concrete, pouring concrete and filling in the first pouring space 31 and the second pouring space 32.

[0105] Specifically, the pouring structure in S3 is poured into a plate as a whole in this step, and the pouring method has the following several kinds:

[0106] In this step, please refer to Figures 1-4 , the pouring concrete is horizontally poured and formed; the first concrete layer 31a is poured on the pouring platform, the pouring thickness of the first concrete layer 31a is not greater than the thickness of the first pouring space 31, and when it is not coagulated, the hollow inner mold net plate positioning pouring structure is placed flat on the first concrete layer 31a, one end of the tie rod 21 (actually the second positioning member 23) is supported on the pouring platform or the pouring formwork (which can be the rear-dismantling pouring formwork 4a or the free-dismantling pouring formwork 4b), and the first concrete layer 31a is located in the first pouring space 31; then the second pouring space 32 is poured and vibrated until the hollow inner mold net plate positioning pouring structure is poured and filled.

[0107] Alternatively, in this step, please refer to Figures 1-4 , and combine Figure 7 and Figure 8 , the pouring concrete is vertically poured and formed by rear-dismantling formwork.

The positioning and pulling piece 2 includes two second positioning pieces 23, which are respectively arranged at the two ends of the pulling rod 21. The pulling rod 21 is arranged in the pouring formwork 4b on both sides of the hollow inner mold net plate positioning pouring structure.

Specifically, in the prior art, the first structural reinforcement 6a or the second structural reinforcement 6b includes a horizontal reinforcement, a vertical reinforcement and a stirrup to form a reinforcement cage, which is poured into the concrete as a structural member. In this embodiment, the plurality of positioning and pulling pieces 2 are arranged at uniform intervals, which can eliminate the horizontal reinforcement. Moreover, the pulling rod 21 of the positioning and pulling piece 2 is in a fixed state after being positioned by the first positioning piece 22, and the vertical reinforcement of the first structural reinforcement 6a or the second structural reinforcement 6b can be directly tied or welded on the pulling rod 21, which can also eliminate the stirrup to complete the overall fixation, greatly saving the cost and time, simplifying the construction steps, and reducing the labor cost on site.
