Background of BAR introduction

  • In a rib-shaped slab, the rib portion requires shear reinforcement bars, but in the past, dozens of reinforcement bars were manually worked one by one, which required a lot of manpower and caused problems in quality deterioration.
  • When shear reinforcement bars and main reinforcement bars were pre-assembled, they were connected only with tie lines, which made them become easily deformed during transportation, and thus could not maintain consistent quality.

Effect of applying bar

  • Not only the shear reinforcement bars but also the main reinforcement bars are manufactured in one piece, which is economical as it reduces a lot of work time and labor.
  • On-site bar placement is easy.
  • It is structurally advantageous as the upper and lower fixation effects are good.
  • The upper exposed surface of the shear reinforcement bar is of the closed type, so it does not interfere with walking, thus improving safety.

Features of lattice bar

  • The ridge and pitch are integrated at regular intervals (200-500mm).
  • The ridge section is processed horizontally, making on-site bar placement easy, and eliminating the need for a separate space bar.
  • The lattice bar and lower main reinforcement bar are automatically welded.
  • The lattice bar and lower main slab reinforcement bar are automatically welded.
