The edge sealing angle steel 5 is fixed to the cantilever steel beam 11 by welding. After being aligned in place and fully welded, the edge sealing angle steel 5 can play the role of enclosing concrete slurry and prevent leakage.

[0021] Among them, a plate edge steel plate 14 is fixedly connected to the side of the steel structure side beam 4 away from the cantilever steel beam 11, and a stiffening steel plate 3 is fixedly connected to the plate edge steel plate 14 and the side opposite to the steel structure side beam 4. The plate edge steel plate 14 is made of thick carbon steel plate, and the plate edge steel plate 14 is processed in the form of folding instead of bending to produce an irrational plate edge line, which is convenient for reducing the difficulty of prefabrication of the plate edge steel plate 14. After the plate edge steel plate 14 is processed, it can be fixed on the steel structure side beam 4 by welding.

[0022] In this embodiment, the top of the plate edge steel plate 14 is fixedly connected with an edge banding plate 13, and the edge banding plate 13 is L-shaped. The edge banding plate 13 can be prepared by a bending processing method, and can be welded to the plate edge steel plate 14 after processing, so as to further restrict the flow of concrete slurry; the top of the plate edge steel plate 14 is fixedly connected with a curtain wall embedded part 7 located between the edge banding plate 13 and the edge banding angle steel 5.

[0023] In this embodiment, the concrete structure includes a steel hoop 10 installed in the building element 1, and a reinforcing steel frame 8 is installed on the steel hoop 10. The number of steel hoops 10 is multiple, and the edge lines of two adjacent steel hoops 10 are offset, so that the steel hoops 10 are conveniently distributed in the building element 1 in a wave shape, thereby facilitating the improvement of the stability of the concrete after pouring; the reinforcing steel frame 8 is composed of a plurality of transverse steel bars 801 and longitudinal steel bars 802, and the longitudinal steel bars 802 are installed on the steel hoop 10, and the transverse steel bars 801 are installed on the longitudinal steel bars 802, so that the reinforcing steel frame 8 cooperates with the steel hoop 10 to form a steel bar frame, so as to improve the strength of the concrete.

[0025] The beneficial effects of the above embodiments are:

[0026] The prefabricated irrationalized plate edge line structure is easy to construct and install. The preparation and positioning of all components of the prefabricated plate edge 2 are completed in the processing plant, including the pre-embedded curtain wall parts 7, the steel bar binding, and the edge sealing plate 13 welding. It can effectively shorten the on-site installation period, reduce the high-altitude operations during the construction of the prefabricated plate edge 2, and reduce safety hazards. Moreover, by prefabricating in the processing plant in advance, the problem that the steel bars cannot pass through the surrounding truss floor decking is avoided, the accuracy of the components and embedded parts is guaranteed, and the construction difficulty is reduced. In addition, the plate edge steel plate 14 is used as the concrete template, which reduces the erection of the support frame and the on-site installation work, saving costs.

[0027] The working principle of the above embodiment is:

[0028] The prefabricated irrationalized plate edge structure which is easy to construct and install, firstly, needs to process the plate edge steel plate 14 of the irrationalized plate edge in the form of folding instead of bending, and weld the plate edge steel plate 14 to the steel structure edge beam 4, then weld the edge sealing plate 13 to the plate edge steel plate 14, and weld the edge sealing angle steel 5 to the steel structure edge beam 4, so that the steel structure edge beam 4, the plate edge steel plate 14, the edge sealing angle steel 5 and the edge sealing plate 13 form a mold base which determines the shape of concrete pouring;

[0029] After that, according to the positioning of the embedded parts in the plane in the curtain wall detailed design drawing, the curtain wall embedded parts 7 need to be placed in the predetermined position in the mold base and welded, and then the steel hoops 10, the transverse steel bars 801 and the longitudinal steel bars 802 are arranged and tied. After the tying is completed, the external formwork is supported, and the mold base is filled with cast concrete 9, thereby completing the prefabrication of the plate edge structure;

[0030] During on-site installation, the connection method between the board edges is to reserve a 800mm wide post-casting section 12. According to the design of the structure, the prefabricated board edge 2 is hoisted in the same direction in a clockwise or counterclockwise direction. After the first piece is hoisted, the curtain wall embedded part 7 needs to be inserted into the reinforcement steel frame 8 from the reserved post-casting section 12, and then the second prefabricated board edge 2 is installed. The reinforcement steel frame 8 of the prefabricated board edge 2 is overlapped and welded through the reserved length;

[0031] After all installation steps are completed, the elevation and entry and exit positions of the slab edges are re-measured. When the accuracy requirements are met, the concrete pouring of the post-casting section 12 and the rigid connection or bolting of the cantilever steel beam 11 and the steel structure side beam 4 are carried out.
