Locking bar for fixing building aluminum formwork

The utility model discloses a locking bar for fixing a building aluminum template, which comprises a locking bar body, bending parts are arranged on two sides of the locking bar body, a mounting part is arranged at the bottom of the locking bar body, a mounting hole is formed in the mounting part, and a reinforcing part is arranged at the edge position, close to the mounting hole, of the mounting part. Compared with the prior art, the bending parts are arranged on the locking bar body, the size of an inlet of the locking bar body at the mounting groove can be reduced when the locking bar body is mounted, and therefore after the locking bar body deforms to a certain degree, the size between the ends of the two bending parts is still smaller than the size of the inlet of the mounting groove; therefore, the locking bar body can still be installed in the installation groove, the calibration frequency of the locking bar body is greatly reduced, meanwhile, the reinforcing part is arranged at the installation hole,
