Referring to fig. 1-4, a combined energy consumption connecting piece comprises an embedded part 2, an energy consumption part 8 and a connecting plate 5.
The two embedded parts 2 are connected through the energy dissipation part 8, the embedded parts 2 are connected with the energy dissipation part 8 in a clamped mode, the two sides of the energy dissipation part are provided with the connecting plates 5, and the two ends of each connecting plate 5 are connected with the two embedded parts 2 respectively.
Specifically, a through clamping groove is formed in the embedded part and is matched with a clamping structure at the end part of the energy consumption part 8, the clamping structure at the end part of the energy consumption part is assembled in the clamping groove, and the energy consumption part 8 is connected with the embedded part.
The clamping groove is a T-shaped groove or a dovetail groove, the two embedded parts are arranged oppositely, the opening sides of the clamping groove are opposite, and the two embedded parts are connected through the energy dissipation part to form a connecting piece.
The clamping groove is preferably a T-shaped groove, the energy dissipation piece is of an H-shaped structure, and two ends of the energy dissipation piece are connected with the clamping groove.
The draw-in groove of built-in fitting adopts clearance fit's mode to be connected with the joint structure of power consumption piece, is formed with the clearance between draw-in groove and the joint mechanism, and the width in clearance is 2mm to coating has lubricating oil on the inner wall of draw-in groove and the outer wall of joint structure, is provided with the steel sheet in the clearance, is convenient for dismantle after impaired.
The energy dissipation part is made of lead materials, the connecting plate is made of a low-yield-point steel plate, and the yield point of the embedded part is larger than that of the connecting plate.
The connecting plate is provided with slotted holes 7, the length direction of the slotted holes is horizontally arranged, the slotted holes are arranged at intervals from top to bottom, and two ends of the connecting plate are provided with fixing holes 6 connected with the embedded parts. The end part of the embedded part is provided with a plurality of bolt holes 3, and a fastener penetrates through the fixing hole 6 and the bolt holes 3 to connect the embedded part and the connecting plate.

The special stress law of the wall body is as follows: in the first stress stage, when the wall 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 are stressed together, and the connecting piece does not consume energy. And when the load is increased to enter a second stress stage, the lead energy dissipation part is stressed beyond the elastic limit to generate plastic deformation to enter an energy dissipation state, and the connecting plate is still in the elastic stage. And (3) along with the further increase of the load, the energy dissipation part has large plastic deformation in a third stress stage, the stress of the connecting steel plate exceeds the elastic limit, and the plastic deformation begins to occur, so that the lead core and the connecting steel plate consume energy together.
