[0040] The sunken grooves 38 at the through holes 34 ensure the edge state of the frame 31, that is, when the frames 31 are spliced, the steel bars 32 are located inside the frame 31 without protruding outward, which can ensure the splicing effect between the frames 31, and when the frames 31 are spliced in a staggered manner, the steel bars 32 extend to the inside of another frame 31 and are connected with the steel bars 32 inside.

[0041] In a further embodiment of the first embodiment, the connecting pieces 33 are located inside the frame 31 and connect the two steel bars 32 at the cross position, and the connecting pieces 33 form a limit for the vertical movement of the transverse steel bars 32 and a limit for the horizontal movement of the vertical steel bars 32.

[0042] Due to the great concrete pressure of the integrated pouring, in order to ensure the position stability of the steel bars 32 inside the frame 31 and avoid displacement, the connecting pieces 33 are used to limit the cross position of the steel bars 32, so as to ensure that the position of the steel bars 32 is always in a relatively stable state, and avoid the situation that the building strength is uneven after pouring due to the slippage of the steel bars 32.

[0065] The two adjacent rib plates form ∧ or ∨ and generate a gap therebetween, the rib plates are extruded when the support seat moves, the rib plates are changed from ∧ or ∨ to a transition, the gap gradually reduces in the transition process, and the rib plates abut against each other.

[0066] When the support seat 613 slides to extrude the rib plates 612, the rib plates 612 are righted from the originally inclined and separated arrangement, the two side-separated rib plates 612 abut against each other in the righting process, the rib plates 612 form a support for the profile steel in the abutting state, and the stability of the profile steel is ensured.

[0067] In addition, when the profile steel side is impacted, the inner collapse is generated, and at this time, since the rib plate 612 is arranged on the upper and lower sides of the support base 613, the rib plate 612 increases the extrusion degree of the support base 613 during the inner collapse, further limits the stability of the support base 613, guarantees the stability of the steel bar 32 through the support base 613, the steel bar 32 is combined with the profile steel, and the stability and strength of the prefabricated part 3 are further enhanced.

[0068] In summary, the technical scheme disclosed in the above embodiment of the application has at least the following advantages: The stability of the steel bar and the frame is enhanced to guarantee the strength of the prefabricated part after the prefabricated part is combined with the floor slab area and the shear wall area, so that the steel bar and the cold-bending profile steel do not slip, deform or locally collapse during pouring, and the cooperative working performance among the steel bar, the cold-bending profile steel and the concrete is maximized.

[0069] The steel bar is bent at the two end positions and connected with the cold-bending profile steel, and the steel bar is positioned to avoid position deviation, so that the anchoring strength and the pull-out resistance of the steel bar are greatly improved, and the earthquake force can be effectively transmitted from the steel bar to the profile steel and the core concrete.

[0070] The two ends of the bent steel bar are pulled through the arrangement of the pull plate, and during pouring, the concrete pressure makes the pull plate bend, and the bending of the pull plate is used to further enhance the stability of the two ends of the steel bar, avoid the deviation of the steel bar, and improve the stability of the prefabricated part during concrete pouring.

[0071] The pull plate and the slide plate are used to limit the steel bar at different positions, so that the steel bar can be guaranteed to have additional stability after being inserted into the frame, and the direction of the prefabricated part can be adjusted according to the flow state during concrete pouring, so that the steel bar is stably supported in the impact direction, and the slip during concrete pouring is avoided.

[0072] Although the application is disclosed in combination with the above embodiments, it is not intended to limit the application, and any person skilled in the art can make various modifications and decorations without departing from the spirit and scope of the application, therefore, the protection scope of the application should be defined by the appended claims.
