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 structures are promoted to form beam hinge sidesway mechanism.
Utility model content
The purpose of this utility model is to overcome the problems that unbonded prestressed concrete structure energy dissipation capacity is poor, carry
A kind of automatic control dissipative cell suitable for unbonded prestressed reinforced concrete frame supplied, the element enbrittle the characteristic of destruction,
From heavy and light, easy construction.This is novel to meet the needs of fast industrialization, can Fast Installation, easy for construction, installation cost at the scene
It is cheap, start a new way for popularization of the unbonded prestressed reinforced concrete frame structure in earthquake territory.
The technical solution adopted in the utility model is：A kind of automatic control suitable for unbonded prestressed reinforced concrete frame is consumed energy
Element, 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 to connect with transfer, deformation box by construction structure glue, the deformation box is by two pieces of trapezoidal side shields and one piece
Rectangle bottom plate is made, and bottom plate both sides are equipped with locating bar, and deformation box is internally provided with filled and process, 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, thickness 10mm, length is wider than the deformation box both sides
50mm。
Preferably, the deformation box side shield is all made of carbon fiber with bottom plate and is made.
