Description
Technical field
The utility model is related to a kind of constructional engineering frame structure systems, specifically the prestressing force prefabrication and assembly construction of automatic control energy consumption
Formula frame structure.
Background technology
In traditional cast in place frame, structure is mainly consumed energy by the plastic deformation of itself, there are remnants after earthquake
Deformation brings difficulty to repairing with follow-up use.Speed of production is fast, quality is steady although having for assembled steel reinforced concrete frame
It is fixed, save the advantages that template, but the node connection reliability of traditional fabricated construction is poor, thus the application of earthquake territory by
To limitation.By whether needing rear pouring concrete, the connection of frame that can generally be divided into two kinds of " wet connection " and " involvement connects ", the former
Apply at present more, and a difference of " involvement connects " is：In wet connection frame, the plastic deformation for designing permission is often set
The region other than bonding pad is set, bonding pad keeps elasticity；And the frame of " involvement connects " then makes every effort to prefabricated components and is maintained at elasticity
Range, plastic deformation are controlled as possible in bonding pad itself.Energy dissipation capacity using the assembling frame of " involvement connects " is weak, and beam column exists
Occur relative rotation when, beam-ends concrete can go out earlier current situation crush it is bad, to influence integrally-built anti-seismic performance.
Existing research generally suggests that frame structure includes that unbonded prestressed reinforced concrete frame structure uses hybrid energy dissipation
Mechanism carries out Aseismic Design, and beam hinge energy consumption mechanism is better than mixed energy dissipation mechanisms.Because beam cuts with scissors energy consumption mechanism and mainly relies on
The plastic hinge of beam-ends removes dissipation seismic energy, not high to the Ductility Requirement of styletable, the curvature that beam hinge requires critical cross-section
Ductility increases few；Mixed energy dissipation mechanisms are that beam hinge and column is relied on to cut with scissors dissipation seismic energy simultaneously, so the section to styletable is prolonged
Property has higher requirement.
Utility model content
The purpose of the utility model is to overcome traditional cast-in-place prestressed reinforced concrete frame and prefabricated PCs
The deficiency of concrete frame provides a kind of prefabricated assembled frame of prestressing force for the automatic control energy consumption meeting conceptual Design of Earthquake Resistance theory
Structure, it is good, simple from heavy and light, construction which has played unbonded prestressed concrete fabricated construction cracking resistance deformation performance
Just recoverable advantage and after shake, promotes the use prestressing without bondn prefabricated assembled concrete frame construction and starts for earthquake territory
One new way.
The technical solution adopted in the utility model is：A kind of prefabricated assembled frame structure of prestressing force of automatic control energy consumption, packet
Include concrete column and no-bonding pre-stress concrete beam；
The concrete column includes automatic control dissipative cell, spacer bar, stirrup, the vertical muscle of column, presstressed reinforcing steel anchored end, angle steel
And friction bolt；Unbonded prestressing tendon in the no-bonding pre-stress concrete beam is anchored at concrete column suspension column, institute
Unbonded prestressing tendon to be stated to arrange for curved shape, the automatic control dissipative cell is set at unbonded prestressing tendon anchorage bearing,
The end of unbonded prestressing tendon is connect with presstressed reinforcing steel anchored end, and the stirrup indulges muscle setting, stirrup and positioning steel around column
Muscle welds, and automatic control dissipative cell is welded with spacer bar；The angle steel by friction bolt be fixed at concrete column capital with
Improve the local bearing capacity of bean column node.
The automatic control dissipative cell includes in bearing plate, side shield, deformation box main body, deformation box exterior portion and deformation box
Side section, the deformation box main body both sides are deformation box exterior portion and deformation box inboard portion, deform box main body and side shield
Lower edge by building structure glue connection, top edge and the bearing plate of the side shield pass through building structure glue connection.
Preferably, the stirrup encrypts setting at automatic control dissipative cell.
Preferably, the bearing plate is steel plate, carbon fiber board component and carbon cloth gluing based on the deformation box
Into (deformation box is to improve intensity, mitigation weight using the purpose of carbon fibre material), the side shield is made of plank.
Advantageous effect：The utility model is disposed with automatic control dissipative cell at curved shape unbonded prestressing tendon anchorage bearing
Unbonded prestressed reinforced concrete frame, automatic control dissipative cell is in a dormant state under frequently occurred earthquake and middle shake；Meet ground rare
The lower automatic control dissipative cell bearing capacity of shake reaches threshold value, then starts and deforms, the anti-bending bearing capacity of Vierendeel girder is caused to reduce
And beam is made plastic hinge occur prior to column.Frame under earthquake by the rotation of the plastic hinge of beam-ends come the inputting seismic energy that dissipates,
Form beam hinge.I.e. under rarely occurred earthquake, artificial control is consumed energy with beam, and the damage to ensure column is lighter, this meets antidetonation
Conceptual design.Presstressed reinforcing steel stress is much smaller than limit stress after forming plastic hinge due to this Vierendeel girder, it is ensured that presstressed reinforcing steel exists
Beam occur plastic hinge it is subsequent it is continuous play a role, to extend Constrained surrender elastic-plastic phase length, form ductile frame.
