For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0018] This embodiment provides a prefabricated integrated exterior wall leveling hanging point assembly. Figure 1 It includes two leveling hanging point devices 1 and two round head hanging nails 2. The two leveling hanging point devices 1 are respectively pre-buried at the two ends of the top of the bay window side panel 210 of the prefabricated integrated exterior wall 200, and the two round head hanging nails 2 are respectively pre-buried at the two ends of the top of the prefabricated integrated exterior wall 200.

[0019] Please refer to Figure 2 The leveling hanging point device 1 includes a threaded steel sleeve 11 and a dovetail threaded anchor steel bar 12. The bottom end of the threaded steel sleeve 11 has a through hole 111. The dovetail threaded anchor steel bar 12 passes through the through hole 111 and is bent into a dovetail shape according to design requirements to form the leveling hanging point device 1.

[0020] Specifically, the threaded steel sleeve 11 includes an integrally formed inner thread 112 and a through hole 111 , wherein the inner thread 112 is used to connect a lifting ring, and the through hole 111 is used to connect a dovetail threaded anchor steel bar 12 .

[0021] Specifically, the dovetail threaded anchor steel bar 12 passes through the through hole 111 of the threaded steel sleeve 11 and then bends to form two bent portions, and the two bent portions expand from the through hole 111 toward both outer sides to form an inverted V shape, and the expansion direction of the two bent portions is parallel to the width direction of the bay window side panel 210. Therefore, the dovetail threaded anchor steel bar 12 has a larger contact area with the inside of the bay window side panel 210, thereby ensuring the connection strength between the dovetail threaded anchor steel bar 12 and the bay window side panel 210, and even if the thickness of the bay window side panel 210 is relatively thin, the leveling hanging point device 1 can be used.

[0022] In order to further strengthen the connection strength between the dovetail threaded anchor steel bar 12 and the bay window side plate 210, please refer to Figure 3 In this embodiment, the dovetail threaded anchor steel bar 12 is welded and fixed to the steel mesh 211 in the bay window side panel 210 .

[0023] During the process of hoisting the prefabricated integrated exterior wall, the use of the leveling hanging point assembly allows the hanging point arrangement of the prefabricated integrated exterior wall 200 to be adjusted from linear to planar, so as to achieve the effect of adjusting the level of the component. When the prefabricated integrated exterior wall 200 is hoisted into place, it is ensured that the prefabricated integrated exterior wall 200 can fall vertically, so that the vertical rebar holes in the prefabricated integrated exterior wall 200 can be installed in one-time alignment with the vertical steel bars on the floor, reducing the hoisting positioning time and ensuring the quality of the installation; at the same time, since the hanging points are evenly stressed and have a strong connection strength with the prefabricated integrated exterior wall 200 and its bay window side panels 210, it effectively prevents the hanging points from being pulled off during the hoisting process, thereby improving construction safety.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
