Description
Technical field
The utility model belongs to building field, particularly a kind of full prefabricated PC concrete frame.
Background technology
Prestressing force is used for reducing or offsetting the concrete pulling stress caused by load, so as to by the tension control of structural elements
System is in smaller range, even in pressured state, to postpone the appearance of distress in concrete and development, so as to improve the cracking resistance of component
Performance and rigidity.The advantages of prestressed concrete frame, is as follows：1st, crack resistance is good, and rigidity is big.Due to applying prestressing force to component,
The appearance in crack has been postponed significantly, under working load effect, component can occur without crack, or postpone crack and occur, so
The rigidity of component is improved, adds the durability of structure.2nd, material is saved, reduces deadweight.Its structure is due to that must use height
Strength materials, therefore amount of reinforcement and sectional dimension of members can be reduced, steel and concrete are saved, dead load is reduced, to big
Span and heavy load structure have obvious superiority.3rd, the vertical shear and principal tensile stress of beams of concrete can be reduced.In advance should
The Curved steel bar (beam) of power beam beams of concrete can reduce the vertical shear in beam near bearing；Again due on concrete section
Prestressed presence, the principal tensile stress under load action is set also to be reduced by.This is beneficial to the web thickness for reducing beam, mixes prestressing force
Solidifying Tu Liang deadweight can further reduce.4th, the stability of compression member is improved.When compression member slenderness ratio is larger, by
Just easily it is bent after to certain pressure, so that losing stable and destroying.If applying prestressing force to reinforced column, make
Reinforcement pulls tight, and not only deformed bar is not easy to bend in itself, and can help the concrete of surrounding
Improve the ability that resistance is bent.5th, the fatigue performance of component is improved.Because there is powerful prestressed reinforcing bar, in service stage
Stress variation amplitude caused by loading or off-load is relatively small, so fatigue resistance can be improved, this is to bearing dynamic load
Structure for be highly advantageous.6th, prestressing force can as structural elements connect means, promote large-span structure new system with
The development of construction method.In the existing Industrial and Civil Engineering pile foundation in China, largely using prestressed concrete pipe pile
Or the pile foundation of steel-pipe pile.But because the reason such as prestressed concrete pipe pile or the mechanical property of steel-pipe pile and cost of investment and
Influence its use.
