One side surface of the edge sealing steel plate 1 forms the boundary of the rear opening. The filling groove is the space between the side surface of the edge sealing steel plate 1 away from the rear opening and the steel truss floor deck 7. The first side surface 3 is the side surface of the steel truss floor deck 7 that contacts the filling groove. Each reinforcing steel bar 4 is the original floor slab reinforcing steel bar of the steel truss floor deck 7 passing through the first side surface. 3. The portion extending into the filling groove is fixedly connected to the reinforcing steel 4 and the edge sealing steel plate 1. The concrete body 5 is formed by pouring concrete into the filling groove. After the edge sealing steel plate 1 is fixed to the steel beam 8, the opening boundary is determined. The edge sealing steel plate 1 can improve the structural strength while acting as an edge sealing template, avoiding the process of setting up templates and supports separately. By using the original floor slab reinforcement of the steel truss floor deck 7 as the reinforcing steel 4 and pouring concrete body 5 into the filling groove, the edge of the opening of the steel truss floor deck 7 can be stably filled, improving the structural stability and simplifying the construction process.

[0028] In a preferred embodiment, the anchoring steel bars are arranged in parallel, which makes the stress more uniform and further enhances the stability of the structure.

[0029] In a preferred embodiment, the concrete of the concrete body 5 is micro-expanding fine stone concrete, which can effectively control the generation of cracks and ensure the compactness of the cast concrete, thereby ensuring the durability of the patching structure.

[0030] In a preferred embodiment, the concrete strength grade of the concrete body 5 is one grade higher than that of the steel truss floor support plate 7, which improves the strength grade of the concrete body 5 and enhances the load-bearing capacity of the steel truss floor support plate rear opening edge patching structure.

[0031] In a preferred embodiment, the steel truss floor support plate rear opening edge patching structure further comprises a plurality of shear studs 6, each shear stud 6 is arranged along the length direction of the top surface of the steel beam 8, and the arrangement of the shear stud 6 improves the shear capacity of the structure and enhances the stability of the overall structure.
