Summary:The invention discloses a device and method for tightening a ceiling rib expansion bolt and relates to the technical field of construction tools. The side face of an inner hexagonal sleeve is provided with a notch, the symmetrical plane of the notch of the inner hexagonal sleeve is welded to the upper end of an adjusting vertical pipe, a welding point is formed, and the lower end of the adjusting vertical pipe is connected with a force arm horizontal pipe. Operators stand on a floor to utilize the principle that the inner hexagonal sleeve and a rod piece are utilized to plug an expansion bolt of a ceiling rib in a ceiling drill hole and the moment is applied through a cross rod at the lower end of a vertical rod to generate torque to tighten the expansion bolt, the expansion bolt of the ceiling rib can be plugged in a ceiling hole very conveniently and tightened, the device saves time and labor during the installation and tightening and is safe and high in efficiency.
