The accurate marking plate construction control method of large-scale separate type, comprises the following steps:
(1) by workpiece handling on the workpiece support bar of workpiece support system;
(2) regulate the trimming bolt 3 of leveling device, the projection of the longitudinal midline of workpiece web on marking plate plate is overlapped with the vertical line of cross position line on marking plate plate;
(3) regulate the jack 7 of vertical adjusting apparatus, the position in fine adjustment workplace vertical direction, makes the web of workpiece all in the same plane and parallel with marking plate plate everywhere;
(4) steel ruler is used to measure on the flange plate of workpiece and mark the vertical position of horizontal location line, then with this position for starting point, use vernier height gauge on the flange plate of workpiece, draw a circle horizontal location line, the position of rebound 2 is the height regulating vernier height gauge height to deduct rebound;
(5) with the nearest marking plate plate cross position line x wire of workpiece Nodes for benchmark, calculate and use steel ruler to measure and mark the position of the vertical position line of workpiece Nodes, use square coordinates, and flange plate draws the vertical position line of each Nodes;
(6) the cross position line setting-out on workpiece flange plate completes, and by workpiece handling to job shop, with cross position line for benchmark, puts the cage plate being drilled with gauge orifice in exact position using the processing of accurate digital control drilling machine, match-drill.
Component in Practical Project be the skimble-scamble large H-shaped steel of size as workpiece 5, and every root component needs drilling hole amount many, position accuracy demand is high.Therefore have employed that web position of center line on two blocks of flange plates of component is each accurately draws a horizontal location line, and drawing a vertical position line at each node location of flange plate, horizontal location line and vertical position line form the cross position line of each node location jointly.Then with cross position line for benchmark, put the cage plate being drilled with gauge orifice in exact position using the processing of accurate digital control drilling machine, match-drill.
Have employed the technical scheme that workpiece support system and marking plate system are separated, ensure that workpiece does not directly contact with marking plate system, avoid the frequent contact-impact platform surface of a large amount of large-scale workpiece, ensure that the precision of platform surface for a long time.Marking plate system adopts 4 pieces of 2m × 1.4m × smart mach marking plate plate in 0.2m surface, the 2 meters of methods be mounted on platform frame in every block landing slab interval, between landing slab, the setting-out of part uses the transit bridge processed by H profile steel to carry out transition, this transit bridge upper and lower surface carries out smart machined by grinding machine, ensure that the flatness of upper and lower surface and the depth of parallelism on two surfaces.Both evaded and directly smart mach difficulty had been carried out to the macrotype platform plate of 14 meters long, again the direct saving cost of landing slab nearly 50%.
Transverse support bar upper level in workpiece support system, lower than marking plate plate upper surface 50mm, can not contact with workpiece support system when ensureing that transit bridge is put on marking plate plate; Longitudinal workpiece support bar upper level in workpiece support system is higher than marking plate plate upper surface 450mm, ensure when the workpiece (H profile steel) with maximum flange plate height is put on longitudinal workpiece support bar, its flange plate lower limb can not contact with marking plate; In 6 transverse support bar, the two ends of every root are all provided with a set of workpiece side to micromatic setting, amount to 12 covers, the lateral position of fine adjustment workpiece (H profile steel), ensure that the projection of longitudinal midline on marking plate plate of workpiece (H profile steel) web overlaps with the longitudinal midline of marking plate system; In 6 transverse support bar, 1 vertical fine-adjustment jack all can be placed in the position be positioned under workpiece (H profile steel) edge of a wing, the position of fine adjustment workpiece (H profile steel) vertical direction, ensures that the web of workpiece (H profile steel) is all in the same plane and parallel with marking plate everywhere.
After workpiece (H profile steel) position adjustments, use vernier height gauge on the flange plate of workpiece (H profile steel), draw horizontal location line, marking plate plate is interrupted part and uses rebound transition (height of vernier height gauge reduces the height 150mm of rebound); Measure with steel ruler and mark the position of vertical position line, using square to coordinate and draw vertical position line.
Due to the complexity that large bridge is built, and bridge is built in specific environment, its skeleton structure is all adopt the skimble-scamble large H-shaped steel of size, and every root component needs drilling hole amount many, position accuracy demand is high, those skilled in the art cannot be carried out setting-out accurately, once there be the position setting-out in a hole to occur error, the position deviation in other holes or assembling is just easily caused to occur interfering, bridge member is caused to assemble, cause waste of material, and consume the duration, the mode that the present invention takes marking plate system to be separated with workpiece support system, workpiece is avoided to contact with marking plate, the precision on long-term guarantee marking plate surface, and devising easy to be each to auxiliary micromatic setting, the position between fine adjustment workpiece and marking plate, ensure that the accurate quick line drawing of a large amount of great components, marking plate is designed to 4 pieces of separate type platforms, ensure that the machining accuracy of platform surface, and saved cost, achieve marked improvement and outstanding substantive distinguishing features, greatly increase efficiency of construction and shorten construction period, for bridge construction, there is outstanding meaning.
As mentioned above, the present invention can be realized preferably.
