Furthermore, the load conical plate is circular configuration setting, and the centre of load conical plate, which is equipped with, is convenient for stress
The aperture that rod iron passes through, the inside of load conical plate are equipped with the cone structure of protrusion.
Furthermore, the stress rod iron using strand structure be arranged, the two ends of stress rod iron be respectively equipped with
The external screw thread that deformed bar anchorage is equipped with.
Furthermore, the deformed bar anchorage uses fixture nut.
A kind of folder steel wire rubber strip reeled tubing of presstressed reinforcing steel hole pore-forming, application method the following steps are included:
1) the folder steel wire rubber strip that producer processes is placed on flat ground, by stress rod iron one end from spring like
The center insertion for pressing from both sides steel wire rubber strip reeled tubing one end, until the end of stress rod iron one end is another in folder steel wire rubber strip reeled tubing
It emerges one end；
2) two ends for pressing from both sides steel wire rubber strip reeled tubing are padded as gasket with load conical plate respectively, then with fixation
Nut fastening applies pressure to folder steel wire rubber strip reeled tubing, eventually becomes hollow tubular；
3) folder steel wire rubber strip reeled tubing is mounted on scheduled position on the framework of steel reinforcement of prestressed concrete, with fixation
Reinforcing bar binding and fixing are good；
4) it is completed in concreting, after concrete solidifies completely, loosens fixture nut, and by stress rod iron 4 from duct
Middle extraction；
5) outer drawing outside one end of folder steel wire rubber strip is caught, whole folder steel wire rubber strip can be pulled out, be repeated after cleaning
It uses.
The invention has the advantages that:
The present invention uses such structure setting, will press from both sides the compression of steel wire rubber strip reeled tubing with punching rod iron when installing and squeeze
Close, forming one has certain longitudinal rigidity, and has certain flexible tubular structure to loosen axial pressure after the completion of concrete
Power, the strand that haulage clip steel wire rubber strip is reeled tubing one, is pulled outwardly, and will can easily press from both sides steel wire rubber strip reeled tubing pull-out-hole
Hole, to achieve the purpose that pore-forming.
