Description
Technical field
The present invention relates to civil engineering technical field of anti-seismic reinforcement, specifically a kind of band is encorbelmented attached prestressing force dress outside plate framework
Structure with formula power consumption frame strengthening.
Background technology
From froming the perspective of in traditional sense, the approach for improving the shock resistance of concrete frame structure is broadly divided into raising carrying energy
The seismic force (energy-dissipating and shock-absorbing reinforcing) three that power (intensity type reinforcing), raising ductility (reinforcing of ductility type), reduction are acted in structure
Plant major way.It is to be supported by increase, increase seismic structural wall, earthquake resistant wall, set up outside framework, increase former frame structure to improve bearing capacity
The modes such as sectional dimension, improve the shock resistance of structure；It is by carrying out ductility reinforcing to component, such as to post increase to improve ductility
The modes such as stirrup, encased steel plate hoop, carbon fiber confinement improve component ductility to improve the ductility of structure；Energy-dissipating and shock-absorbing is set to fill
Put, be by setting the dissipation such as damper, earthquake isolating equipment tectonic comparison or cut-off seismic energy input, being caused with mitigating earthquake
Influence.
Additional overall minor structure reinforce be exactly the additional overall minor structure of utilization and original structure collaborative work, not only can be with
Be effectively improved the overall stress of structure, improve the anti-seismic performance of structure, and during strengthening construction can as far as possible not in
The normal of disconnected building structure is used, and the concrete condition that can be combined with building creates abundant architectural effect, be it is a kind of it is economical,
Rationally, efficient structural system reinforcement means.
Most outer monkshood structural strengthenings need to carry out the cast-in-place operation of minor structure at present, can produce pollution and noise, and apply
The work cycle is numerous and diverse very long.In addition, there is a kind of special connection in outer monkshood structural strengthening, i.e. the overhanging balcony of former frame structure
Or outside corridor cantilevered plate, cause outer monkshood structure can not be fitted with former frame structure.
