[0021] like Figure 1 , Figure 2 As shown, a parapet wall formwork structure comprises:

[0022] A connecting piece 1, wherein the connecting piece 1 is fixedly connected to the edge beam of the steel structure;

[0023] A prefabricated component 2, the bottom of which is fixedly connected to the connecting piece 1, and a connector 3 is embedded in the prefabricated component 2;

[0024] An inner formwork 4 is arranged opposite to the prefabricated component 2 and fixedly connected to the connector 3; the prefabricated component 2 and the inner formwork 4 form a casting cavity 5 for casting concrete to form the parapet.

[0025] In principle, the prefabricated component 2 can be made of wood, steel or plastic, and PC material is recommended. By making the prefabricated component 2 into a required shape in advance, it can be suitable for the casting of various irregular walls.

[0026] The parapet wall formwork structure further comprises steel bars, which are arranged in the casting cavity 5 and overlapped and tied with the prefabricated components 2. By arranging the steel bars in the casting cavity 5, the strength of the parapet wall can be enhanced.

[0027] The parapet wall formwork structure also includes a supporting steel pipe 6, one end of which is connected to the inner support formwork 4, and the other end is in contact with or fixed to the floor, so as to directly support the inner support formwork 4 from the inside, thereby improving the stability of the formwork support.

[0028] The connecting piece 1 is an angle steel, which is easy to purchase, has high strength, and has many specifications, and is suitable for a variety of usage scenarios.
