Definitions

  • the present invention was made to overcome these defects described above, and provides a hydraulic jig for correction of mis-alignment between the joints of plates characterized in that two jig beams are provided so that the plates to be joined may be clamped from both sides thereof with hydraulic jacks and by utilizing a plurality of holes drilled in said plates whose joints are to be aligned; and a plurality of hydraulic jacks for pressing said plates against a plurality of backing straps attached to one of said jig beams so as to correct misalignment between the joints of said plates are mounted on the other jig beam.
  • FIG. 1 is a top view of a jig of the present invention used for correction of mis-alignment between the joints;
  • FIG. 2 is a front view thereof;
  • FIG. 3 is a sectional view taken along the lines A-A of FIG. 1;
  • FIG. 4 is a side view looking in the direction indicated by the arrows B of FIG. I; and
  • FIG. 5 is a fragmentary transverse sectional view of a transverse frame in a vessel.
  • the embodiment is for correcting mis-alignment between web plates 1 and l of transverse frame in a vessel as shown in FIG. 5.
  • a frame 5 carries a pair of 6-ton hydraulic jacks 3 for clamping and one 2-ton hydraulic jack 4 for correction of mis-alignment.
  • a plurality of such frames 5 similar in construction are spaced apart from each other on a beam 2 ofajig in the longitudinal direction thereof.
  • a plurality of 2-ton hydraulic jacks 4 are also attached on the beam 2 in spaced apart relation.
  • a backing pad or strap 7 for correction of misalignment is disposed in opposed relation with the hydraulic jack 4 mounted on the frame 5.
  • Another jig beam 6 having a plurality of frames 8 disposed in opposed relation with the frames 5 on the jig beam 2 is provided.
  • Holes 10, 75 80 mm in diameter are drilled in the web plate 1 at the positions at which the hydraulic jacks 3 are placed when the jig beam 2 with the construction described above is placed in front of the joint 12 of the web plate 1, so that the rods 1 1 of the hydraulic jacks 3 may extend through the holes 10 beyond the web plate 1 and be coupled to the frames 8 of the jig beam 6 with pins 9 as best shown in FIG. 3.
  • the web plates 1 and l are sandwiched between the pair ofjig beams 2 and 6, and the mis-alignment in the joint 12 can be corrected with the hydraulic jacks 4 and the backing straps 7.
  • the jig beam 2 is placed in front (bow of fore) of the joint 12 between the web plates 1, whereas the jig beam 6 is placed on the back (stem or aft) side of the joint by using suitable lifts.
  • the rods of the hydraulic jacks 3 on the jig beam 2 are extended through the holes 10 in the web plates 1 and connected to the frames 8 of the jig beam 6 with the pins 9 as best shown in FIGS. 1 and 3.
  • the jig beams 2 and 6 are coupled to each other with the web plates 1 sandwiched therebetween.
  • the present invention has been described as being applied to the web plates of the transverse frame in a vessel, but it should be understood that the jig of the present invention may be also applied to web plates used in the structures other than vessels. Various modifications and variations of the jig device can be effected without departing from the scope of the present invention.
  • the joints between flat plates are clamped by a plurality of hydraulic jacks utilizing a plurality of holes drilled in the plates in the manner described above, and the mis-alignment between the joints can be corrected with a plurality of other hydraulic jacks and the backing straps.
  • the correctionof misalignment can be accomplished in a simple manner, and the need of a large quantity of mis-alignment correction pieces can be eliminated.
  • the operation can be accomplished within a short time in a very efficient and simple manner.
  • Ajig for aligning a pair of plates edge to edge prior to welding comprising: two elongate jig beams between which a margin of one of said plates may be held with an edge projecting, and a plurality of hydraulic jacks, some of said jacks being arranged in pairs and arranged to hold the beam together and the remaining jacks being spaced along one of said beams and acting against backing pads equivalently spaced along the other beam to grip, and adjust the position of, the margin of the other of said plates whereby the plates may be brought edge to edge for welding, a plurality of frames spaced along the beams, each frame possessing a first portion attached to one beam and a second portion attached to the other beam; each frame holding one of said pairs of jacks with the body of each jack on one frame portion and the jack rod of each jack on the other frame portion, whereby the rods can be passed through correspondingly spaced holes in the margins of the respective plates and upon contraction the jacks move the beams together.
