Description
Technical field
The utility model relates to a kind of reinforced bar stretching aid for prestressed concrete.
Background technology
In the construction of post-tensioned method prestressed concrete box beam was produced, stretch-draw prestressing force was one critical process that the case beam is produced.Because the prestressed concrete box girder volume is very huge, stretch-draw is very heavy with jack, the stretch-draw frame of existing carrying jack is difficult for moving usually, and the stretch-draw frame does not possess the function of fast simple accurate mobile stretch-draw jack, causing changeing the top operation carries out slowly directly affecting the convenience and the progress of construction.Therefore, it is one of critical process equipment of prestress engineering that prestressing force is tried to stop people from fighting each other, and is badly in need of improving.
The utility model content
The purpose of this utility model provides a kind of post stretching box girder tensioning frame, solve the heavy difficult technical problem that the top operation is carried out slowly, do not possessed fast simple accurate mobile stretch-draw jack that moves, changes of traditional stretch-draw frame.
For achieving the above object, the utility model adopts following technical scheme:
A kind of post stretching box girder tensioning frame, comprise the stretch-draw frame body, it is characterized in that: the end face of described stretch-draw frame body has set up the rail road at fore-and-aft direction, be welded with the end face steel plate above the rail road, hang respectively on two bottom flanges in rail road and connect a pair roller, roller shaft is by the coaster motor-driven, connect the coaster frame plate between two roller shafts of homonymy, connect crossbeam between the two coaster frame plates in the outside, suspension is connected with and pulls electric block on the crossbeam, and the footing of stretch-draw frame body is connected with universal pulley by wheel carrier.
Described stretch-draw frame body is welded into up-small and down-big frame construction by horizontal main joist and vertical main joist.
Described horizontal main joist and vertical main joist are steel pipe or shaped steel, and the rail road is an i-beam track.
The side of described stretch-draw frame body is connected with simple and easy ladder.
The opposite of the tension operation face of described stretch-draw frame body has been welded to connect vertical steel plate.
Compared with prior art, the utlity model has following characteristics and beneficial effect:
The utility model is according to requiring both sides, two ends synchronous tension simultaneously in the tensioning process, the a branch of characteristics that move that all need to carry out support body of every stretch-draw, connect universal pulley in the prestressing force bottom surface of trying to stop people from fighting each other, the stretch-draw frame can be moved easily, make the commentaries on classics top work of jack convenient and swift.The stretch-draw frame body adopts the steel pipe welding production to form, and is simple in structure, firmly, can repeatedly have enough to meet the need use.Added a vertical shift coaster that can move along track at the top of stretch-draw frame body, the vertical shift coaster mainly be responsible for the stretch-draw jack to the hole lashing, the vertical shift dolly of stretch-draw top of the trellis change stretch-draw frame in the past use in jack be difficult for the problem of mobile contraposition, can carry out vertically moving of stretch-draw jack very easily, simultaneously, be equipped with pull electric block after, can simply accurately jack be aimed in place fast.Solved the heavy difficult technical problem that the top operation is carried out slowly, do not possessed fast simple accurate mobile stretch-draw jack that moves, changes of traditional stretch-draw frame.
