Description
Technical field
The present invention relates to building engineering field, and in particular to a kind of Self-resetting device for swinging structure.
Background technology
Swinging structure is to be constrained between loosening configuration and basis between constraint or component, makes to contact between structure and basis or component
Only have compression capability at face and without tension ability, then structure is waved under geological process, knot is made by deadweight or prestressing force
Structure resets, and forms swinging structure and runback bit architecture.There are some researches show waving for structure reduces geological process and structure
The Ductility Design demand of itself, reduces eaerthquake damage, has saved structural cost.Swinging structure can recover functional structure
A kind of important way of realization, it can be not only used for the energy-dissipating and shock-absorbing of new building, and the antidetonation for being also applied for existing building adds
Gu.The canonical form of swinging structure is framework-wave wall construction, and framework-wave wall construction can play control structure deformation
Pattern, the overall energy dissipation capacity of structure is played, realizes and can recover after macroseism with runback bit function etc..Swinging structure is currently with frame
There is more wide application prospect in the existing public buildings seismic hardening in the majority of frame structure type.
At present, in addition to using deadweight, the method for realizing swinging structure Self-resetting is embedded through structural elements (such as wall
Body) and basis presstressed reinforcing steel, as shown in figure 1, by tensioned prestressing bar to component produce prestressing force come realize structure from
Reset.On the one hand this method is unfavorable for the arrangement at structural member (hole on such as wall), and another aspect presstressed reinforcing steel is in foundation beam
The anchoring construction great difficulty of bottom surface can not even be realized at all.
The content of the invention

(such as wall) and the presstressed reinforcing steel on basis, is unfavorable for the arrangement at hole on wall, while the reserving hole on wall is needed, behaviour
Make step cumbersome；Anchoring construction of the presstressed reinforcing steel in basic soffit is difficult.
The present invention takes following technical scheme：
A kind of Self-resetting device for swinging structure, including core mandrel 1, first end plate 2, disk spring combination 3, second
End plate 4, outer tube wall, connecting plate 8；The disk spring combination 3 is enclosed on outside core mandrel 1, the inner side of first, second end plate 2,4
Face is close to be arranged on 3 two ends of disk spring combination respectively, and the outer tube wall carries out axial limiting to first, second end plate 2,4；
Connecting plate 8 described in second end plate 4 is fixedly connected with outer tube wall；When core mandrel 1 is by pulling force, core mandrel 1 is subjected to displacement, and drives the
Two end plates 4 are inwardly subjected to displacement and extrude disk spring combination 3；When core mandrel 1 is stressed, reverse displacement occurs for core mandrel 1,
Drive first end plate 2 to be inwardly subjected to displacement and extrude disk spring combination 3；The Self-resetting device of the swinging structure is fixed vertically
Between foundation beam and swinging structure.
Further, the outer tube wall includes outer tube wall 1 and outer tube wall 27, and both are threadedly coupled.
Further, the end of the core mandrel 1, is fixed with nut 5, for second positioned at the outside of the second end plate 4
The progress of end plate 4 is acted on and spacing.
Further, the disk spring combination 3 is all the time in the state being pressurized.
Further, second end plate 4 is flange.
Further, the core mandrel 1 is attached with foundation beam by pre-embedded steel slab.
The beneficial effects of the present invention are：
1) presstressed reinforcing steel need not be set, be conducive to the arrangement at hole on wall；
2) without the reserving hole on wall, implement more convenient；
3) it is attached between easy construction, with foundation beam by pre-embedded steel slab, it is easy to connect, reliably.
4) gone out using disk spring as core energy-dissipating and shock-absorbing and Self-resetting original paper by the composite assembly of disk spring
Required capability and deformation amount, and pass through a kind of outer tube wall constructing apparatus so that no matter whole test specimen is in pulling force or pressure
Under power effect, disk spring combination is all in pressured state all the time, to provide the restoring force needed for Self-resetting.
5) outer tube wall constructing apparatus is detachable, and main parts size can carry out normalization factory process, then tighten spelling
Dress, can easily realize industrialized production, make simple, cost is relatively low, easy to maintenance, with extensive popularization and application valency
Value.
