Description
Technical field
The invention belongs to prestressed, reinforced engineering device technique fields, more particularly to a kind of small-sized prestressed concrete soil block steel
Rib prestressed device.
Background technique
Prestressed concrete occurs too early in order to avoid the crack of reinforced concrete structure, make full use of high strength cast iron and
Strong concrete is tried before concrete structure or component bear working load, by applying external force, so that component generated
Tensile stress reduces, even in the concrete component under compressive stress state.
Purpose compressive pre-stress is used to reduce or offset concrete pulling stress caused by load, thus by the drawing of structural elements
Stress Control is in smaller range, even in pressured state, to postpone the appearance and development of distress in concrete, to improve component
Cracking resistance and rigidity.
Crack resistance is good, and rigidity is big, due to applying prestressing force to component, the appearance in crack has been postponed significantly, in working load
Under effect, crack can not occur in component, or postpone crack and occur, so improving the rigidity of component, increase the resistance to of structure
Long property.
Reinforced steel bar strength wants high, and the tension stress of deformed bar will appear each in the entire production of component and use process
Kind stress loss.The summation of these losses can reach 200N/mm² or more sometimes, if reinforced steel bar strength used is not high, that
Established stress can even lose totally when tension.
Existing prestressed concrete soil block production, pre-tensioning system need stretching bed seat；Post stretching also to consume quantity it is more,
The anchorage etc. of reliable in quality.Just seem trouble in small-sized prestressed concrete test block production, to deformed bar device
Not simple enough, the tension stress for the deformed bar for drawing pedestal to pull will appear each in the entire production of component and use process
Kind of stress loss, use cost is high, one kind can simple operations, and the reinforcing bar that can complete small-sized prestressed concrete soil block is pre-
The device urgent need of stress.
Summary of the invention
The purpose of the present invention is to provide a kind of prestressed, reinforced devices of small-sized prestressed concrete soil block, pass through flexible dress
Setting can be by reinforcement metal straightening, to one tensile stress of reinforcing bar, spiral shell in the second support component and the top effect of stretching tensed between support component
