    • An apparatus (“chair”) for supporting one or more reinforcement bars or post-tension cables (“bars/cables”) in a concrete structure includes a base member having a centered opening, a pair of opposing first leg members extending upward from the base member at a first angle, a pair of opposing second leg members extending upward from the base member at a second angle, and a strap-shaped locking cradle. The strap-shaped locking cradle includes an arc-shaped receiving portion attached to the first and second leg members, a flexible portion suitable for wrapping over the bars/cables and a fastener to affix the flexible portion to the arc-shaped receiving portion or one of the first leg members such that transverse and vertical movement of the bars/cables is limited and longitudinal movement of the bars/cables is allowed.
    • 用于在混凝土结构中支撑一个或多个加强筋或后拉电缆(“杆/电缆”)的装置(“椅子”)包括具有中心开口的基部构件,从第一支撑构件向上延伸的一对相对的第一腿构件 第一角度的基部构件,以第二角度从基部构件向上延伸的一对相对的第二腿部构件和带状锁定支架。 带状锁定支架包括附接到第一和第二腿部构件的弧形接收部分,适于缠绕在杆/电缆上的柔性部分和紧固件以将柔性部分固定到弧形接收部分或一个 的第一腿构件,使得杆/电缆的横向和垂直运动受到限制,并且允许杆/电缆的纵向移动。
