Construction method for deformation joint formwork of high-rise building

The invention relates to a construction method for a deformation joint formwork of a high-rise building. The construction method comprises the steps of formwork making, formwork mounting and formwork removal. The formwork is made by using double layers of formworks to be spliced in a staggered mode; and after the working procedure of formwork making, the formwork is strengthened by the combination of a rigidity support formed by welding of a phi 12-16 bolt two-way fastening screw with the length being 890-910 mm and two phi 20-24 rebars side by side and supporting rebars formed by welding of basket-type split bolts and two phi 8-12 rebars placed on a floor side by side, so that a split bolt strengthening system is formed. The construction method for the deformation joint formwork of the high-rise building has the advantages that through the improvement of the formwork configuration and strengthening process, the construction difficulty is greatly reduced, the working efficiency is improved, and a variety of d
