Two horizontal girder moving channels (12), a horizontal concrete steel rail pedestal (14) and horizontal girder moving steel rails (13) are arranged on a concrete bar-shaped foundation base (1) for making a girder, and the horizontal girder moving channels (12) are arranged on the back-and-forth horizontal direction in parallel mode. Horizontal girder moving sliding plates (15) and girder moving sleepers (16) are arranged on the horizontal girder moving steel rails (13) in moving mode. Pre-cast girders are arranged on the girder moving sleepers (16), and bottom die steel plates (5) on two ends of the concrete bar-shaped foundation base (1) for making the girder are respectively provided with a top girder preset opening (18). Pre-cast girder support base plates (20) are fixed on the top girder preset openings (18) through fixing bolts (19). Jacks (17) are arranged below the top girder preset openings (18). The post-tensioning method pre-stressed girder horizontal girder moving system is particularly suitable for being applied to girder making factories.

The specific embodiment
A kind of post tentioned prestressed concrete girder laterally moves the girder system system, comprise two beam concrete bar shaped pedestals 1 processed that arrange at left and right sides longitudinal direction that are parallel to each other, on every beam concrete bar shaped pedestal 1 processed, all be embedded with the fixedly pre-buried channel-section steel 2 of steel work beam making bench, the horizontal long girder steel 3 of the steel work beam making bench of horizontal direction and laterally short girder steel 11 before and after the compartment of terrain is fixedly installed on pre-buried channel-section steel 2, laterally long girder steel 3 and laterally short girder steel 11 alternate intervals settings, at horizontal long girder steel 3 with laterally lack girder steel 11 and be fixedly installed the many vertical square steel 4 that arrange at left and right sides longitudinal direction that are parallel to each other, be fixedly installed bottom die of precast beam steel plate 5 at vertical square steel 4, on the two ends end face of the horizontal long girder steel 3 of steel work beam making bench, all be movably set with side form pad 6, be provided with precast beam side form 7 at side form pad 6, beam concrete bar shaped pedestal 1 processed be provided with two mutually parallel in front and back in a lateral direction laterally move beam passage 12, in laterally moving beam passage 12, be provided with horizontal concrete rail pedestal 14, laterally the height of concrete rail pedestal 14 is identical with the height of beam concrete bar shaped pedestal 1 processed, make whole Liang Chang accomplish basic barrier free accessibility, before and after laterally concrete rail pedestal 14 is provided with in a lateral direction laterally move joist steel rail 13, be movably set with and laterally move beam slide plate 15 laterally moving joist steel rail 13, be provided with and move crown plate wood 16 laterally moving beam slide plate 15, be provided with precast beam moving crown plate wood 16, bed die steel plate 5 at beam concrete bar shaped pedestal processed 1 two ends is respectively arranged with a back timber reserved opening 18, set bolt 19 is fixed on precast beam holder base plate 20 on the back timber reserved opening 18, is provided with jack 17 below back timber reserved opening 18.When moving beam, with two jack 17 with beam jack-up a little, after extracting cover plate out, to laterally move beam slide plate 15 and move crown plate wood 16 and be placed on and laterally move on the joist steel rail 13, the end face that moves crown plate wood 16 exceeds 10 decimeters than bottom die of precast beam steel plate 5, then fall two jack 17, beam is sitting in moves on the crown plate wood 16, beginning laterally moves beam.
Between the beam concrete bar shaped pedestal 1 processed on the two parallel left and right sides longitudinal directions, be provided with steam-cured pipe 8, be provided with steam-cured pipe steam control valve 10 at steam-cured pipe 8, between bed die steel plate 5 and side form 7, be provided with sealing joint strip 9.Be the beam humidification in the time of in the winter time, improve the quality of beam and the setting time of shortening beam.
According to beam field construction requirement, design the beam making bench arrangement form, straddle truck is walked the position of line and horizontal the way of moving the beam.According to beam field site condition, such as the rail height of the transverse and longitudinal gradient, use, back timber point height, deposit the composite factor analysis such as beam pedestal height and specify the way of moving the beam absolute altitude.At first first beam making bench basis and straddle truck are walked the line basis and built and finish, strict elevation control in the casting process, the height on beam making bench basis has determined the height of the way of moving the beam, has determined that also the straddle truck of crossing that whether can stride walks line.Because some will be fixed on the way of moving the beam on the beam making bench strip foundation, if the beam making bench basis is lower slightly, can also meet design requirement by increasing steel plate washer, if be higher than design elevation, dealing with will be pretty troublesome, and deviation is too large, and fixedly the way of moving the beam scheme will be failed.Next carries out the installation of steel work base frame mould, girder steel is pressed the layout design arrangement position accurately and the pre-buried channel-section steel welding of strip foundation, and prepares the movable die block position is reserved, and back timber is put the position reserve.Be fixed at last traversing beam slideway and straddle truck and walk the line rail, if normally put in place by design elevation control, install just very simply, only need to be placed in rail on the traversing beam slideway and straddle truck is walked on the line basis, passage embedded bar railway spike is fixed track.
