The production method of tension reinforcing steel bar is also referred to as pre-tensioning system before solidifying soil, it plays an important role in engineering construction.
After pre-tensioning system stretching wire, when steel wire there are enough cohesive forces with concrete, is opened by putting, unclamp steel
Silk, by means of the bonding of concrete and steel wire, guarantees that prefabricated components reach design requirement.It develops now a kind of using force-transmitting pole
The pre-stress construction pedestal of stress, including pedestal and the force-transmitting pole for being arranged in pedestal two sides, pedestal both ends are provided with fixation
Gooseneck, one end are additionally provided with movable gooseneck, and anchoring has steel between the activity gooseneck and the fixation gooseneck of opposite side
Silk, is provided between ipsilateral fixation gooseneck and puts equipment, the effect of the fixation gooseneck at pedestal both ends in tension stress
Under, it is pressed in power transmission column end, puts and opens while to realize steel wire on the pedestal, that is, guarantees that steel wire puts the synchronism opened, needs
It wants matched and puts a constructing device.
Floor deformed bar tensioning prestressed reinforcement of tensioning before floor concrete casting.Due to pre-stress floor size
It is different, and different floor set aside pre-embeddeds position is different, causes prestressed stretch-draw mold design specification more, installation is troublesome in poeration,
It is easy error.
