Binding method for wall steel bars

The invention discloses a method for binding wall steel bars, which comprises the following steps of: straightening a reserved lap joint rib of a poured wall to enable the reserved lap joint rib to be vertical to a floor slab; a plurality of main reinforcements are bound with the reserved lap joint reinforcements, and the lap joint lengths of the main reinforcements and the reserved lap joint reinforcements are determined; the lap length is expressed by a formula: L = X * beta * eta; the multiple main reinforcements are bound to form double-layer reinforcement structures, the double-layer reinforcement structures are connected through tie bars, and the distance between the double-layer reinforcement structures is determined according to the thickness of the wall; a plurality of transverse bars are sequentially arranged in the longitudinal direction of the double-layer steel bar structure and connected with a plurality of main bars respectively, and the main bars are perpendicular to the transverse bars to for
