A self-resetting energy-dissipating support includes inner restraint pipes, outer restraint pipes, wide ear plates, shear rivets, lead sand, outer restraint pipe ear plates, partitions, fixed end plates, cables, clamps and anchor plates. In the factory, the wide lugs, shear rivets and inner restraint pipes are welded and assembled first, and the outer restraint pipe ear plates, partitions and outer restraint pipes are welded and assembled, and then the inner restraint pipes are arranged in the outer restraint pipes, and the outer restraint pipes are assembled. The restraint tube is re-welded and connected, and then the cable of the self-resetting system is inserted into the inner restraint tube, and then passed through the opening of the fixed end plate, and the fixed end plate is tightly pressed against the two ends of the outer restraint tube by applying prestress, tensioning The cable is anchored to the anchor plate with a clamp, and finally the lead sand is injected through the pouring hole to form a lead core, and the assembly is completed. The welding and assembling process of the present invention is all completed in the factory, and has the advantages of remarkable energy consumption effect due to the friction between the shear rivet and lead sand, strong self-resetting ability and high industrial production efficiency.
