[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0017] Refer to Figures 1 - 3, A reinforced aluminum alloy formwork for post-cast belt construction, comprising a formwork body 1, a formwork reinforcement frame, adjustable back ribs and high-strength connection components. The formwork reinforcement frame is welded to the back of the formwork body 1. The adjustable back ribs include a main back rib 6 and a plurality of auxiliary back ribs 5. The main back rib 6 is arranged on the side of the formwork reinforcement frame away from the formwork body 1 along the height direction of the formwork body 1, and is fixedly connected to the formwork body 1 through high-strength connection components. The plurality of auxiliary back ribs 5 are arranged at intervals on the side of the main back rib 6 away from the formwork body 1. The auxiliary back ribs 5 are arranged along the width direction of the formwork body 1, and the auxiliary back ribs 5 are fixedly connected to the main back rib 6 through high-strength connection components.

[0018] In this embodiment, the formwork reinforcement frame includes transverse ribs 2 and longitudinal ribs 3. The longitudinal ribs 3 are arranged along the height direction of the formwork and are welded to the back of the formwork body 1. The transverse ribs 2 are arranged along the width direction of the formwork and are fixedly welded to the longitudinal ribs 3. The longitudinal ribs 3 and the transverse ribs 2 together form a formwork reinforcement frame for supporting the formwork body 1.
