Embodiment
As shown in Fig. 1,2,3,4,5, a kind of prestressing force metal damper, comprise Wasted-energy steel plate 9, the both sides of described Wasted-energy steel plate 9 are all longitudinally installed with end plate 4, at the top fixed cover plate 1 of Wasted-energy steel plate 9, lower cover plate 2 is fixed in the bottom of Wasted-energy steel plate 9, pre-pull bar 3 is movably installed with between upper cover plate 1 and lower cover plate 2, the longitudinal direction of the Wasted-energy steel plate 9 between two end plates 4 is provided with radial rib plate 6, the Wasted-energy steel plate 9 between two end plates 4 be provided with horizontal floor 5 in a lateral direction.
Described pre-pull bar 3 is movably arranged between upper cover plate 1 outside end plate 4 and lower cover plate 2, limiting stopper 7 is provided with at the two ends of pre-pull bar 3, upper cover plate 1 and lower cover plate 2 are arranged between two limiting stoppers 7, are all provided with set screw nut 8 in the outside of each limiting stopper 7.Described upper cover plate 1 and lower cover plate 2 are and arrange reeded platy structure, and Wasted-energy steel plate 9 is fixedly mounted in the groove of upper cover plate 1 and lower cover plate 2, and upper cover plate 1 is identical with the shape of lower cover plate 2, and the installation direction of upper cover plate 1 and lower cover plate 2 is contrary.Described horizontal floor 5 is at least two pieces, and two pieces of horizontal floor 5 equalizations are arranged on the Wasted-energy steel plate 9 between two end plates 4, between horizontal floor 5 and on the Wasted-energy steel plate 9 of horizontal floor 5 and upper cover plate 1 and lower cover plate 2, be installed with radial rib plate 6.Described radial rib plate 6 is two pieces, and two pieces of radial rib plate 6 correspondences are arranged on the both sides in the middle part of Wasted-energy steel plate 9, and the height of radial rib plate 6 is equal with the height of Wasted-energy steel plate 9.
In use, main component is Wasted-energy steel plate 9 to this product, and Wasted-energy steel plate 9 both sides arrange the horizontal floor 5 of multiple tracks and radial rib plate 6, to ensure that Wasted-energy steel plate 9 Wasted-energy steel plate under very big shear deformation all the time plate unstable phenomenon does not occur.Wasted-energy steel plate about 9 two ends connect upper cover plate 1 and lower cover plate 2 respectively, and upper cover plate 1 can be connected with construction element with lower cover plate 2.Outside end plate 4, install pre-pull bar 3 between upper and lower cover plates, pre-pull bar 3 end passes upper cover plate 1 and lower cover plate 2, and is connected with set screw nut 8 with limiting stopper 7.
Before damper is installed on structure, by set screw nut 8, pre-pulling process is carried out to pre-pull bar 3, apply pulling force effect to pre-pull bar 3 two ends, this effect is converted to the pressure effect to Wasted-energy steel plate by upper cover plate 1 and lower cover plate 2, and Wasted-energy steel plate horizontal section produces compressive pre-stress; During earthquake, when the damper upper and lower cover plates be installed in structure is out of shape with deformation of member generation shear displacemant, drives Wasted-energy steel plate generation shear deformation, thus produce shearing stress in Wasted-energy steel plate; Owing to there being the existence of compressive pre-stress, then shearing stress, or shear deformation does not need very large, and the combined stress in Wasted-energy steel plate can reach conversion yield stress, thus enters surrender power consumption state.
