Abstract
The invention discloses a mould supporting method for a trapezoid cross section base of a shear wall. The method adopts a mode that split bolts are fixed with wall plate ribs, support bolts are fixed with base plate ribs and limit short ribs are arranged on the split bolts and the support bolts to determine support mould points of two waist mould plates of the trapezoid cross section base and ensure that the geometrical size of the trapezoid section is controlled. Lateral pressure bearing capability of the waist mould plates is improved by means of reinforcing square columns to prevent deformation and mould expansion. Double-frame pipes, butterfly fasteners and wedge gaskets are adopted to fix the mould plates, the wall plate ribs and the base plate ribs to ensure that the axis of the trapezoid cross section base is not offset in the concrete pouring process.
