Auxiliary welding device for wall column positioning steel bars

The utility model relates to an auxiliary welding device for a wall column positioning steel bar. The technical problem that in the prior art, the perpendicularity of a wall column does not meet the requirement easily due to the fact that the installation error of the positioning steel bar is large is solved. The fixing device comprises an L-shaped plate and a grab handle, the L-shaped plate comprises a positioning vertical plate and a supporting plate which are perpendicular to each other, the projection of the side face, back to the supporting plate, of the positioning vertical plate in the vertical direction is flush with the side line of the bottom of a wall column on a floor, and the side face, back to the supporting plate, of the positioning vertical plate is used for being tightly attached to the end face of a positioning steel bar. A first limiting plate and a second limiting plate which are parallel to each other are perpendicularly connected to the side face, back on to the supporting plate, of the
