Frame.
Background technique
Reserving hole channel is not needed when binding prestress concrete structure construction, not needing the later period wears muscle and grouting, has and applies
Work is easy to operate, construction quality is easily guaranteed that, short time limit and the advantages that economical rationality, the popular welcome by engineering circles.
Since current specifications has the control of crack grade and anti-seismic construction etc. to require unbonded prestressed reinforced concrete frame,
The margin of safety for increasing Vierendeel girder makes it be not easy to form beam hinge sidesway mechanism under rarely occurred earthquake.It is answered in advance suitable for soap-free emulsion polymeization
The stress of unbonded prestressing tendon under the automatic control dissipative cell of power concrete (UPPC) frame can act on to adjust and reduce rarely occurred earthquake,
UPPC frame structure is promoted to form beam hinge sidesway mechanism.
Summary of the invention
The purpose of the invention is to overcome the problems, such as that unbonded prestressed concrete structure energy dissipation capacity is poor, provide
A kind of automatic control dissipative cell suitable for unbonded prestressed reinforced concrete frame, the element enbrittle the characteristic of destruction, self weight
Gently, easy construction.This is novel to meet the needs of fast industrialization, can at the scene Fast Installation, easy for construction, installation cost is low
It is honest and clean, a new way has been started for popularization of the unbonded prestressed reinforced concrete frame structure in earthquake territory.
The technical solution adopted by the present invention is that: a kind of automatic control energy consumption member suitable for unbonded prestressed reinforced concrete frame
Part, including transfer, bearing plate, deformation box, filled and process and locating bar；
The automatic control dissipative cell is arranged in unbonded prestressing tendon turning point, and unbonded prestressed reinforced concrete frame beam exists
The stirrup of presstressed reinforcing steel turning point encryption arrangement stirrup, the locating bar and presstressed reinforcing steel turning point is welded and is positioned, institute
It states bearing plate and is connect by construction structure glue with transfer, deformation box, the deformation box is by two pieces of trapezoidal side baffles and one piece
Rectangle bottom plate is made, and bottom plate two sides are equipped with locating bar, is equipped with filled and process inside deformation box, prevents the coagulation in casting process
Soil penetrates into dissipative cell, influences dissipative cell function and effect.
Preferably, the transfer is made of circular cylinder steel member and steel plate welding.
Preferably, the bearing plate is made of glass fibre, with a thickness of 10mm, length is wider than the deformation box two sides
50mm。
Preferably, the deformation box side baffle is all made of carbon fiber with bottom plate and is made.
Preferably, the transfer is that circular cylinder steel member and steel plate are formed by welding.
Preferably, the locating bar is semicircle cylinder steel member, and it is connect by construction structure glue with other components.
The key component of bearing plate of the invention as dissipative cell, is transmitted presstressed reinforcing steel by transfer
Load passes to bearing plate by lower steel plate dispersion, improves the bearing capacity of component, enhances energy dissipation capacity.
The utility model has the advantages that a kind of automatic control dissipative cell suitable for unbonded prestressed reinforced concrete frame provided by the invention,
Automatic control dissipative cell is arranged in the presstressed reinforcing steel turning point of unbonded prestressed reinforced concrete frame beam, in small shake and middle shake
In a dormant state, prestressed frame beam works normally dissipative cell；Under rarely occurred earthquake, prestressing force is big to the effect of dissipative cell
In threshold value, then dissipative cell starts and is deformed by design requirement to reduce the stress of presstressed reinforcing steel, reaches reduction prestressing force
The effect of the bearing capacity of Vierendeel girder occurs realizing beam hinge so that beam hinge be made to cut with scissors prior to column.
