[0011] Furthermore, the heads and tails of a row of reinforcing hooks are connected by overlapping joints, and the overlapping joints are connected by reinforcing hook connectors; the reinforcing hook connectors are binding wires.

[0012] Furthermore, the reinforcing bar splice is fixedly connected to the vertical reinforcing bar in the structural steel reinforcement, and the fixing point is connected by a pre-embedded reinforcing bar fastener.

[0013] Furthermore, the pre-embedded reinforcement fixing component includes binding wire, welded steel plate, or fastener.
