Description
Technical field
The present invention relates to a kind of process for prestressed component two directions tension, belong to technical field of civil engineering.
Background technology
At present, prestressed component is widely used in fields such as highway bridge, railroad bridge, side slope antiskids.In advance
Prestressed concrete is to make up the phenomenon that crack occurs too early in concrete, before component use, gives concrete one in advance
Precompression, i.e., in the tensile region of concrete, reinforcing bar is carried out tensioning by the method that manually reinforces, using the retraction force of reinforcing bar,
Concrete in tension area is set to be stressed in advance, this precharge pressure stored, when component bears to produce pulling force by external load,
The precompression in concrete in tension zone is offset first, is then increased with load, is just made concrete in tension, which limits concrete
Elongation, delay or avoid the appearance in crack, this is just called prestressed concrete.
The production in enormous quantities of scale is done step-by-step in the production of prefabricated components, and the span of mould increases, and is realizing prestressing force
When application, occur prestressing force it is larger in the case of, easily make it that die deformation and prestress application are difficult, traditional prestressing force
Tensioning on mould, mostly using mould one end carry out tensioning, also significantly limit the efficiency of production.
It is therefore desirable to invent a kind of method for stretching of new prestressed component to solve the above problems.
The content of the invention
The present invention difficult caused by prestress application, have found for prestressed component and a kind of be used for prestressed component
The process of two directions tension.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of work for prestressed component two directions tension
Process, including the stretching machine provided with pressure gauge, lock sleeve, mould, the first steel of tensioning for placing the prestressed component
Second reinforcing bar of muscle and the prestressed component, in addition to tension ground tackle and connection component；The tension ground tackle is included by preceding
Plate, back plate, upper plate, lower plate, the casing of left plate and right panel composition, the upper plate and the lower plate be symmetrical arranged, the left plate and
The right panel is symmetrical arranged；The foreboard is provided with through hole corresponding with second reinforcing bar, and the back plate and the foreboard are symmetrical
Set；The connection component includes the first sleeve, second sleeve and locking stud, and first sleeve, second sleeve inside are
Provided with screw thread, the locking stud both ends are connected with first sleeve, second sleeve respectively；
The process of the two directions tension concretely comprises the following steps：
Step 1：Make the prestressed component be deposited in the mould, placed at a certain distance from the die nose portion
The tension ground tackle, the through hole of the tension ground tackle are corresponding with second reinforcement location；
Step 2：Barricade is set between the tension ground tackle and the mould, and the barricade is respectively arranged on second reinforcing bar two
Side, the tension ground tackle are fixedly installed with the barricade；
Step 3：Make first reinforcing bar pass through the through hole, and pass through the connection component and second bar connecting；
Step 4：The lock sleeve is inserted on first reinforcing bar, the lock sleeve is located at the outer side through hole of the tension ground tackle
Place；
Step 5：Make the mould rearward end identical with die nose portion arrangement, using stretching machine, make the mould forward and backward
End carries out tensioning simultaneously, and stretching mode is single tendon stretch.
Preferably technical scheme is：The mould ends are 3-5m with tension ground tackle distance.
Preferably technical scheme is：The mould ends are 1-2m with barricade distance.
Preferably technical scheme is：The material of the barricade is concrete.
Preferably technical scheme is：The material of the tension ground tackle is thickness 10-30mm steel plate.
Because above-mentioned technical proposal is used, the present invention this have the advantage that compared with prior art：
The present invention sets up fixed barricade and tension ground tackle using both mold ends, and prestressed stress is shared into the tensioning anchor at both ends
On tool and barricade, mould is not set to undertake prestressing force；The larger situation of prestressing force is directed to simultaneously, when applying prestressing force to reinforcing bar, this
Invention can be achieved both ends and operate prestressed, reinforced application simultaneously, and both ends carry out prestressed stretch-draw simultaneously, can save of half
Draw the time of process.
