The invention discloses an integral bracket construction method for a cover beam, which comprises the following steps: mounting an A-frame and a lifting mechanism on a pier column; paving sleepers on the ground so as to level the ground; connecting I-shaped steel and square steel to form an integral bracket, and then placing the integral bracket on the sleepers; placing corresponding materials on the integral bracket, and lifting the integral bracket by using the lifting mechanism; confirming that the performance reaches the standard in the lifting process of the integral bracket, and then putting the integral bracket into production; fixing the lifted integral bracket on the corresponding position of the pier column; confirming that the integral bracket fixed on the pier column is safe, and then dismounting the A-frame and the lifting mechanism on the pier column; carrying out construction on the pier column; after the construction of the cover beam, lowering the integral bracket onto the ground; and repeating the steps so as to carry out construction of the next cover beam. The integral bracket construction method disclosed by the invention overcomes the problems of high construction difficulty and high cost of the conventional method and is obviously shortened in construction period, high in safety performance, environment-friendly and energy-saving.
