Construction joint control device and construction method thereof

The invention provides a construction joint control device and a construction method thereof. The construction joint control device comprises a transverse support, two vertical supports and two sets of supporting rods; vertical through holes are formed in the transverse support; the vertical through holes are in a long strip shape and formed in the long axial direction of the transverse support; the upper ends of the vertical supports are arranged in the through holes of the transverse support in a penetrating mode and adjustably connected with the transverse support through fixing pieces; the two sets of supporting rods are arranged on the inner sides of the two vertical supports correspondingly, and the supporting rods in each set are alternately distributed in the vertical direction; the two sets of supporting rods are arranged in a one-to-one correspondence mode, and the sum of the length of the two corresponding supporting rods is mutually adaptive with the distance between the two ...
