[0031] Please refer to Figure 1-4 , a steel structure building external formwork, which is used in the field of building formwork, including:

[0032] The template body 1 is made of high-strength steel to ensure its stability and durability during the construction process. Two rectangular protrusions 2 are symmetrically fixed on one side of the template body 1. The two protrusions 2 are used as connection points for plugging with the slots 3 of the adjacent template body 1. On the other side of the template body 1, a rectangular slot 3 corresponding to the rectangular protrusion 2 is provided for receiving the protrusion 2 of the adjacent template, thereby realizing rapid splicing between templates. In order to reduce the weight of the template body 1, a rectangular sunken groove 10 is provided on the back of the template body 1. This sunken groove 10 effectively reduces the material used for the template without affecting the overall strength of the template, reduces the cost, and is easy to carry and install;

[0033] In order to improve the installation and disassembly efficiency of the template, a through-piece is provided on the template body 1, and the through-piece includes an insertion rod 4, and a lifting cap 5 is fixedly provided on the top of the insertion rod 4. When two adjacent template bodies 1 need to be connected, it is only necessary to pass the insertion rod 4 through the first through hole 6 on the rectangular protrusion 2 and the multiple second through holes 7 in the template body 1 to complete the fixation. The multiple second through holes 7 are designed to connect the two rectangular slots 3, ensuring that the insertion rod 4 can pass through the protrusions and slots of the two adjacent template bodies 1 at the same time, so as to achieve rapid fixation;

[0034] In order to reinforce the template body 1 and improve its overall strength, a reinforcement piece is arranged in the rectangular sunken groove 10. The reinforcement piece includes a cross reinforcement frame 11 fixedly arranged in the rectangular sunken groove 10. The cross reinforcement frame 11 is tightly connected to the inner wall of the template body 1 to form a stable supporting structure. In addition, at the right angles of the rectangular sunken groove 10, a reinforcement inclined plate 12 is fixedly arranged. These inclined plates 12 form a stable triangular structure with the inner wall of the template body 1 at right angles, which effectively improves the compressive strength and overall stability of the template.
