    • A post sleeve installation assembly includes: an elastomeric sleeve core shaped to form a post sleeve when positioned in uncured concrete, a removable stiffener inside the core, an aperture extending lengthwise in the stiffener, a locking element positioned within the core, and an assembly plate coupled to the stiffener. The assembly plate clamps to a prefabricated sleeve element, with the core and stiffener positioned within a post cavity of the sleeve element. an installation stake is positioned in the aperture and prevented from sliding upwards by the locking element. A release point on the assembly plate permits an operator to release the locking element for removal of the stake. To install a post sleeve, the operator positions the installation assembly, clamped to a prefabricated sleeve element, in a post hole with the stake resting on the bottom, then fills the hole with concrete, manipulating the stake to position the assembly.
    • 柱套安装组件包括:当定位在未固化混凝土中时成形为形成柱套的弹性体套筒芯,在芯内部的可移除加强件,在加强件中纵向延伸的孔,定位在芯内的锁定元件和组装板 耦合到加强筋。 装配板夹紧到预制套筒元件上,芯部和加强件定位在套筒元件的后腔内。 安装桩被定位在孔中并且被锁定元件阻止向上滑动。 装配板上的释放点允许操作者释放锁定元件以移除桩。 为了安装柱套,操作人员将安装组件固定在一个预制的套管元件上,并将桩放置在底部,然后用混凝土填充孔,操纵桩以定位组件。
