Tie-line problem of engineering reinforcement.

1. Binding of foundation steel mesh. Around the intersection of two rows of steel bars, each point should be fastened, and the intersection of the middle part can be fastened at staggered intervals, but the stressed steel bars shall not be displaced. For the steel mesh with two-way main reinforcement, all steel bar intersections must be fastened. When binding, pay attention to the wire buckle of the eight-shaped adjacent binding point to avoid the skew deformation of the mesh. 2. The beam-column stirrup joints (hook lap) should be staggered on the longitudinal reinforcement at the four corners; The corner of stirrup and the intersection of longitudinal reinforcement should be fastened (the straight part of stirrup and the intersection of longitudinal reinforcement can be fastened at intervals), and the binding buckles should be splayed with each other when binding stirrups.

3. The steel mesh of the wall is bound with the foundation, and the hook of the steel bar should face the concrete.

4. The steel mesh of the wall is bound with the foundation, and the hook of the steel bar should face the concrete.
