Disclosed are a lug for mounting a wedge and a chain block for drawing strands, and a strut having thereof. A drawing strut includes: a drawing wedge for drawing the post-tensioning strands located in an anchor head; the chain block operated by the attractive force of a user and connected to the drawing wedge to draw the strands; the lug for mounting the chain block thereonto; and a strut for fixing the lug thereto and resisting the load generated from the lug upon the drawing of the strands. According to the present invention, the strut can stably support drawing force to allow the drawing force to be easily maintained for drawing the strands and the force generated on the chain block to sustain; thus protecting a worker from safety accidents and making the drawing of the strands to be easily conducted even in a small space to reduce the working time. |
