Standard Method for Fixed Binding of Reinforcement

Page view
  1, beam column (wall) steel placed in the order
        When the beam and the column or the wall side usually, the beam side of the main tendons placed in the column or wall longitudinal longitudinal reinforcement.
 
        2, the frame structure, the primary and secondary beams placed in the order
        In the frame structure, the upper and lower main girders are placed on the upper and lower main bars of the main girder, and the upper and lower main tendons of the frame are placed on the upper and lower main bars of the frame girder.
 
        3, the basis of steel primary and secondary beams placed in the order
        The main reinforcement of the secondary beam is placed under the main bar of the main beam, and the upper layer of the plate is placed under the main reinforcement of the foundation beam.
 
        4, floor (roof) steel placed in the order
        When the two tendons cross, the base floor and the floor of the short span of the upper part of the main tendons should be placed in the long span of the main bar above the short span of the lower main tendons placed in the long span under the main bar.
 
        5, lap within the scope of three points tied
        Each rebar must be lugged at three points in the lap length. With double wire tie lap reinforcement at both ends of the head 30mm, the middle banding together, and over three vertical tendons.
 
        6, lap within the range through the three bars
        Wall vertical reinforcement lap range must ensure that there are three horizontal tendons through the wall horizontal reinforcement overlap must ensure that there are three vertical bars through.
 
        7, shear wall horizontal tendons staggered overlap
        Wall horizontal bar lap joints should be staggered spacing of ≥ 500mm, the same component in the adjacent longitudinal reinforcement of the lap joints should be staggered 50%.
 
        8, the shear wall vertical bar joints staggered
        Shear wall with the adjacent row of two vertical rib joints should be staggered, different rows of adjacent two vertical rib joints should also be staggered from each other. Lap joints staggered 500mm, mechanical connection joints staggered 35d. Note that the length of the lap joint in addition to meet the 1.2laE, but also to meet the overlap within the scope of the three horizontal tendons.
 
        9, stirrup installation
        The main tendons must be in close contact with the stirrups. Lap joints should be made double main stirrups, stirrups hook should be the two main tendons all hooked.
 
        10, positioning stirrup box
        Frame column template on the mouth set positioning stirrup box, used to control the displacement of steel, positioning hoop divided into internal control and external control of two, placed in the top of the column hoop can be used to deal with.
