CONSTITUTION: A multi U-head support apparatus for bridge construction comprises a male screw bar(10), two fixing nuts(18), an upper U-head(20), and a lower U-head(30). A height adjustment bar(12) is fixed at the center of the male screw bar. The male screw bar is comprised of an upper screw thread(14) and a lower screw thread(16). The upper screw thread and the lower screw thread are formed on the outer circumference of the top and bottom of the height control bar. The fixing nut is fixed and coupled on the upper screw thread and the lower screw thread, respectively. The upper U-head is comprised of a U-head channel(22) and a fastening pipe(24). The top of the U-head channel is open. The upper end of the fastening pipe is welded with the lower part of the U-head channel. A female screw is formed inside the fastening pipe, so the fastening pipe is coupled with the upper screw thread of the male screw bar. The lower U-head with the upper surface, wherein a screw-hole is punched, is coupled with the lower screw thread of the male screw bar. |
