High low building-cross deformation joint low section shear wall construction method

The invention discloses a high low building-cross deformation joint low section shear wall construction method. Firstly a suspension device is fixed on the high section completed section shear wall at one side of the deformation joint, the suspension device is provided with a hoisting mechanism; a tower crane is utilized to hoist an outer mould board to the nearby of the hoisting mechanism, and then the outer mould board is suspended on the hoisting mechanism; a plurality of steel bars are arranged below the low section shear wall to be poured, the outer mould board is vertically placed on the steel bar by virtue of the hoisting mechanism; then an inner mould board is mounted, the inner mould board and the outer mould board are arranged in parallel, and finally concrete pouring is carried out between the outer mould board and the inner mould board, concrete is solidified, and then construction of operation layer deformation joint low section shear wall is completed. The invention has the advantages that the outer mould board in the deformation joint is hoisted by adopting the suspension device fixed on the high section completed shear wall and a hoisting tool, the difficulty that the tower crane can not hoist the outer mould board at the deformation joint is solved, and hoisting is carried out when construction of every layer is completed, construction process is greatly simplified, working efficiency is improved, and handlabor is reduced.
