Technical field
Patent of the present invention is related to building element field, more particularly, to a kind of distributed three-dimensional damping thin wall hollow floor.
Background technology
Energy-dissipating and shock-absorbing technology sets energy dissipator by the larger position of some deformations in the structure, or directly some structures
Part is arranged to energy dissipation component.Under earthquake load and wind action, these energy dissipators or component enter power consumption state, consumption
The partially or mostly energy of external loads input structure, so as to reduce the dynamic response of main structure body, avoid or greatly subtract
The possibility that few main structure body destroys.
In Practical Project, it is limited to requirement limitation, the position for being available for energy-dissipating device to install is often very limited, such as reinforcing bar
Concrete shear wall structure or some other structure being had higher requirements to building sides intrinsic permeability.Therefore can many times select
Some components, such as coupling beam or Partial Shear wall member, displacement type dissipative member is made.These components once enter power consumption shape
State, then mean component partial or fully enter irreversible state of plastic deformation, then in geological process or wind action
Afterwards, these components will face repair or remove displacement work, increase considerably the use operating cost of structure indirectly.
Thin wall hollow floor, refer in cast-in-place concrete building roof thin-walled square chest mould built in embedment regularly, make reinforcing bar
Concrete floor system is internally formed the two-way grid of certain intervals, so as to a kind of hollow floor formed, because it may span across intercolumniation
Away from the advantages that larger, materials relatively save, the popularization and application of engineering are gradually obtained, but it does not possess the work(for reducing structural seismic response
Can, and the reaction of itself vertical seismic action can only be reduced by changing construction itself size.
Accordingly, it is considered to which mass tuning device and thin wall hollow floor are organically combined, formed a kind of with obvious
Cushioning effect, and the new structure component of displacement operation need not be repaired or removed after shaking, there are wide market prospects.
