In another embodiment, the pre-buried connector 3 is provided with a plurality of mounting slots, and each mounting slot is fixedly connected with an energy dissipation plate.
The energy consumption principle of the steel plate yield energy consumption type dry connecting piece is that the energy consumption plate made of low yield point steel can enter a plastic stage to begin energy consumption as soon as possible after small elastic deformation, and the slotted hole design of the energy consumption plate can avoid out-of-plane warping so as to exert plastic deformation as much as possible. The energy dissipation plate firstly enters an energy dissipation state, the restraint plate enters the energy dissipation state after the energy dissipation steel plate is subjected to certain plastic deformation and serves as a second energy dissipation defense line of the connecting piece, and the pre-embedded connecting plate is guaranteed not to be subjected to plastic deformation before being damaged, so that the replaceable function of the connecting piece is met.
The special stress law of the wall body is that in the first stress stage, when the wall body is stressed less, the stress of the connecting piece at the joint is less, the connecting piece can provide enough initial rigidity to be in an elastic state, at the moment, the connecting piece and the wall body are stressed together, and the connecting piece does not consume energy.

And (3) with the further increase of the load, the energy dissipation plate has larger plastic deformation in the third stress stage, the constraint plate begins to generate plastic deformation when the stress of the constraint plate exceeds the elastic limit, and the energy dissipation plate and the constraint steel plate consume energy together.
