Description
Technical field
The utility model belongs to Structures Reinforced Technique field, is related to a kind of reinforcing dress for controlling steel strand prestress value
Put.
Background technology
At this stage, the strengthening member method generally used in China's structure engineering design has been broadly divided into two classes：Directly add
Gu and indirect strengthening；
Direct reinforcement means includes following several again：
Reinforcement method of enlarging section can be carried out suitably according to the actual conditions of structure engineering design to the section of concrete
Adjustment, increase area of section, improve section rigidity, improve anti-seismic performance, consolidation effect is reliable, construction is simple.But it reinforces meeting
Reduce existing building space, influence user's use feeling, and it is larger to conduct oneself with dignity, and larger burden can be brought to existing building structure,
So reinforcement cost is often higher, while inevitably situ wet operation can influence construction period, and other are brought for enterprise
Connect cost payout.
Concrete strengthening method is replaced with reinforcement method of enlarging section there is many similitudes, major advantage is to reduce
Space, it will not also change user's use feeling.But the building time for being also required to grow carries out wet trade very much, and it is difficult
Point will have the carrying system that can substitute original component in work progress, to ensure that superstructure is indeformable, does not ftracture.Together
When in substitution reinforcement work progress, it is also contemplated that the increased construction loads of superstructure, there is also very big in this way
Limitation.
Reinforcement by sticking of sheets, along with the maturation of structure cementing agent technology, make the use of stick steel technique more and more extensive.Tying
In the design process of structure engineering, affixing steel plate can be carried out in the region of building element relative deficiency, building element is added
Gu to improve the bearing capacity of building element, work progress is comparatively relatively simple.Reinforcement by sticking of sheets is in the process construction used
Speed, at the construction field (site) without many wet trades, it is only necessary to carry out a small amount of plaster.Life hardly to people and
Production impacts.After building element reinforcing, outward appearance and spatial content on building element all do not influence, but for
It is gluing but to have high requirement, relatively it is applicable in the deformation of member in normal humidity environment.
Indirect strengthening method is divided into following several again：
Increase supporting method for strengthening.Reach consolidation effect by reducing span, construction is simple, reinforce reliable.But to building
Build space to have a great impact, can only be used in the building of conditions permit.
Prestress strengthening method.Prestressing is divided under stress distribution pull bar method for strengthening and prestressing force again supports pull bar
Two kinds of method for strengthening, it is to improve building element possessed bending resistance by reducing the load force in building element, it is known that
Prestressed consolidation technology is applied to bridge strengthening mostly, but reinforcing of the ring orientation prestress for silo and building vertical member etc. is imitated
Fruit is fine, and also in developing stage.
Utility model content
The purpose of this utility model is to provide a kind of bracing means for controlling steel strand prestress value, solves existing tradition
Reinforcing mode waste time and energy, and the problem of cost is higher.
The utility model the technical scheme adopted is that it is a kind of control steel strand prestress value bracing means, including with
In the steel strand wires of reinforcing, the torque wrench for the bar dowel and sleeve of auxiliary application stress and for applying stress, steel strand wires
Both ends are fixed with fixture.
The characteristics of the utility model, also resides in,
Sleeve bottom is symmetrically arranged with a pair of bar dowel bayonet sockets, and bar dowel bayonet socket size is adapted with bar dowel, sleeve top
Portion is provided with the torque wrench hole clipping being adapted with torque wrench one end.
Sleeve is made up of the cylinder of two superpositions, and upper cylinder diameter is less than lower cylinder, and lower cylinder bottom is symmetrical
A pair of bar dowel bayonet sockets are provided with, lower cylinder top is affixed with upper cylinder bottom, is provided with the top of upper cylinder and is pulled with moment of torsion
The adaptable torque wrench hole clipping in hand one end.
Torque wrench is L-shaped, and long side is used to apply stress, and short side one end is adapted with torque wrench hole clipping shape.
Fixture is anchor.
The beneficial effects of the utility model are the utility model control steel strand prestress value bracing means, including for
The steel strand wires of reinforcing, the torque wrench for the bar dowel and sleeve of auxiliary application stress and for applying stress, by short
Reinforcing bar applies moment of torsion to tighten steel strand wires, according to prestress value and moment of torsion corresponding relation, is best suitable for so as to apply to strenthening member
Prestressing force.The utility model greatly simplifies the reinforcing mode of steel strand wires and realizes controllable precise, construction technology is simple and easy to do,
Construction cost is low, construction operation space is small, and effectively increases the bearing capacity and ductility for being reinforced component.
