[0019] 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 creative work shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4, A construction connecting piece for the corner formwork of a special-shaped concrete structure, including a special-shaped corner outer wing main body 1. At the bottom of the special-shaped corner outer wing main body 1, a special-shaped corner inner support frame 2 is fixedly installed. The other end of the special-shaped corner inner support frame 2 is fixedly connected to a special-shaped corner inner wing main body 3. A bolt hole 4 is opened at the top of the special-shaped corner inner wing main body 3. The installation of the special-shaped corner inner support frame 2 at the bottom of the special-shaped corner outer wing main body 1 enables the special-shaped corner inner support frame 2 to install the special-shaped corner inner wing main body 3, making it more convenient to use during operation. At the same time, by using the bolt hole 4 opened at the top of the special-shaped corner outer wing main body 1, wood screws can be used to install the special-shaped corner outer wing main body 1 onto a special-shaped column.

[0021] Please refer to Figure 4 , The special-shaped corner outer wing main body 1 includes a first outer side wing 101. The side of the first outer side wing 101 is fixedly connected to a second outer side wing 102. During the installation of the first outer side wing 101 and the second outer side wing 102, the shape formed by the first outer side wing 101 and the second outer side wing 102 is convenient for installation with special-shaped parts.

[0022] Please refer to Figure 4 , The special-shaped corner inner wing main body 3 includes a first inner side wing 301. The side of the first inner side wing 301 is fixedly connected to a second inner side wing 302. When the first inner side wing 301 and the second inner side wing 302 are installed, it is convenient to use the device.

[0023] Please refer to Figure 4 , The length of the inner wall of the bolt hole 4 on the side of the first outer side wing 101 away from the second outer side wing 102 is 8MM, and the length of the inner wall of the bolt hole 4 on the side of the first outer side wing 101 close to the second outer side wing 102 is 36.5MM. By opening the bolt hole 4, wood screws can be used through the bolt hole 4 to install with special-shaped parts.

[0024] Please refer to Figure 4 , The diameter of the bolt hole 4 is 2.5MM, and the number of bolt holes 4 is multiple. The multiple bolt holes 4 are symmetrically opened at the top of the first outer side wing 101 and the second outer side wing 102. Since the number of bolt holes 4 is twelve, and the twelve bolt holes 4 are symmetrically opened at the top of the first outer side wing 101 and the second outer side wing 102, the special-shaped corner outer wing main body 1 can be used.

[0025] Working principle: During operation, corresponding special-shaped angle connectors are processed according to the angles of the special-shaped angles. The distance between the outer wing body 1 and the inner wing body 3 of the special-shaped angle of the connector is determined according to the thickness of the formwork used in the project. The cut formwork is inserted between the two flanges of the special-shaped angle, and the overall reinforcement of the special-shaped structure is carried out using the outer reinforcement system. Calculate the lengths of the inner and outer formworks of the entire special-shaped column, subtract the length at the position of the inner support frame 2 of the special-shaped angle of the connector, and then cut the formwork according to the actual required size. After inserting the formwork into the gap between the outer wing body 1 and the inner wing body 3 of the special-shaped angle, use wood screws to connect the formwork to the special-shaped connector through the bolt holes 4 reserved on the outer wing body 1 of the special-shaped angle. After the splicing is completed, the shaping plate on one side of the special-shaped column is completed, and the combined plate can be used for the inner and outer side reinforcement of the special-shaped column to form the shape.
