[0002] In building construction, cantilever structures are an important component. Cantilever structures are usually eaves, corridors, balconies, canopies, and some decorative overhangs. Their characteristics are that the overhang length is not large and the load is not large.
[0003] Currently, the construction of eaves structures typically employs a pouring method. This necessitates the erection of formwork on scaffolding outside the building to complete the pouring of the cantilevered concrete structure. This increases the construction time for workers on the outer side of the building's top, compromising their safety. Furthermore, with the support of scaffolding, it is difficult to maintain a level position between multiple base slabs, resulting in unevenness after pouring.

[0022] The working principle of the formwork for the high-altitude cantilevered eaves structure provided by this utility model is as follows:
[0023] In use, the fixed beam 1 is first placed horizontally inside the building 8, with one end extending out of one side of the building 8. The fixed beam 1 is then fixed to the ground inside the building 8 using the fixing member 2, making it the main connecting node for the formwork connection of the building 8. Next, the positioning beam 31 is vertically engaged with the extended end of the fixed beam 1 using the locking block 32, with the top end of the positioning beam 31 abutting against the side wall at the top of the building 8. The bottom end of the positioning beam 31 is then initially fixed in position using bolts. Next, the reinforcing rod 7 is abutted against the inner side wall of the positioning beam 31 and the surface of the fixed beam 1 using the connecting member 61 rotatably connected at both ends. After adjusting its position, the reinforcing rod 7 is fixed between the positioning beam 31 and the fixed beam 1 using bolts, strengthening the stability of the positioning beam 31.

The end abuts against the outer side of the building, and the reinforcing rod 62 is bolted to the inner sidewalls of the positioning beam 31, the support frame 41 and the support beam 5 respectively through the connector 61, so that the positioning beam 31, the support frame 41 and the support beam 5 are connected to form a whole, and the support beam 5 forms a roof structure support platform under the fixed support of the positioning beam 31 and the support frame 41.
