Description
Technical field
The utility model is related to the ductility connecting structure of a kind of assembled vertical member and basis.
Background technology
Prefabricated assembling type reinforced concrete structure the developed countries such as America and Europe, Japan had more practical application and
More mature technical research.In recent years, national development green building greatly develops assembled architecture, promotes construction industry transition
Upgrading.With the quickening of China " building industrialization, housing industrialization " process, the application of fabricated construction building is increasingly extensive,
The practical application and theoretical research that the country builds fabricated construction deepen continuously.
The connection of prefabricated components is to influence one of the key technique of structure safety in prefabricated concrete structure.It assembles whole
Body formula concrete structure is equal with traditional cast-in-place structural entirety stress, and basic assurance is the force modes of connecting node
It can be same or similar with traditional cast-in-place structural joints pattern.The key technique of node connection is exactly between different component
Reinforcing bar connection, the joints pattern that different joint reinforcing bar types of attachment is embodied is different.Assembled architecture knot at present
The common joint reinforcing bar connection type of structure is sleeve grouting connection.
Rarely occurred earthquake acts under force effect, in conventional cast-in-place concrete frame structure, bottom frame column basal cross section stress
Maximum, tension side concrete cracking, tension reinforcement can take the lead in entering plastic strain stage, the reinforcing bar in certain length at this
Plastic deformation is generated, forms plastic hinge, with the increasing of load, column bottom tension side concrete further cracks, tension reinforcement
Strain further increases, and plastic hinge deformation further increases, and strains and then is pulled off until tension reinforcement reaches capacity, structure is broken
It is bad.This destruction is that have apparent destruction sign before structure destruction in the apparent deformation of structure generation, can strive for user
Certain escape time is referred to as " ductile fracture ".For structure under rarely occurred earthquake effect, connecting portion can enter mecystasis
And the connection with the plastic deformation ability met the requirements claims " ductility connection ".The key of ductility connection is connecting node plasticity
The formation of hinge.Two necessary conditions for forming plastic hinge are that column bottom steel bar stress enters plastic strain stress stage and structure for modeling
Property hinge provide certain length formed plastic deformation.
In the case where connecting portion enters mecystasis, the plastic deformation ability that meets the requirements is made it have it is necessary to connect
Socket part position forms plastic hinge.Assembled architecture is frequently with the connection shape being embedded in grout sleeve in concrete prefabricated column at present
Formula, column bottom grout sleeve by bottom with basis bar connecting.Since grout sleeve is not permitted in structure each stress stage
Perhaps it surrenders, i.e., steel bar stress cannot be coordinated to generate plastic deformation, therefore this connection type can not form plasticity in connecting portion
Hinge.To solve the technical barrier that prefabricated post and foundation connection joint in prefabricated concrete structure keep ductility switching performance, one
Kind is particularly important for assembly concrete prefabricated post and basic ductility connection method.
