Scaffold support

A scaffold support (10), one end of which is fixed on a wall surface (3) and the other end of which is coupled to a scaffold (1) so as to fix the scaffold (1) on the wall surface (3), wherein the scaffold support (10) comprises;

• a bracket (20) fixed on the wall surface (3) by fixing means (4, 5);
• a screw axis member (30) having one end coupled to the bracket (20) and a male screw portion (31) on an outer circumferential surface thereof;
• an outer pipe (40) which has an insertion portion (41), in which the other end of the screw axis member (30) is inserted, formed in one end thereof and a closed end surface (43) at the other end thereof, and has a female screw portion (42) being screw-coupled to the male screw portion (31) of the screw axis member (30);
• a pipe rotary shaft (50) which protrudes outward from a center of the end surface (43) of the outer pipe (40), and has a polygonal head (51) at a protruding front end, wherein the polygonal head (51) is inserted in a polygonal groove (72) in a tool coupling portion (71) of an electric wrench (70);
• and
• a clamp (60) having one side rotatably coupled to a clamp coupling groove (53) formed by the end surface (43) of the outer pipe (40), the pipe rotary shaft (50), and the polygonal head (51), and the other side coupled to a scaffold pipe (2) of the scaffold (1) to be attachable/detachable, wherein;
• if the electric wrench (70) is inserted on the polygonal head (51) of the pipe rotary shaft (50) and rotated, the outer pipe (40) is rotated around the pipe rotary shaft (50) and is moved along a longitudinal direction of the screw axis member (30) to be extended and contracted so that a length of the scaffold support (10) can be adjusted according to a distance between the wall surface (3) and the scaffold (1).
