摘要： The invention disclosed here is an anchor bolt holder that is designed to be used in setting an anchor belt in a concrete slab. The holder is a two-part system having a base, and a sleeve connectable to a socket in the base. The sleeve is adapted to receive and hold an anchor bolt's shank. Prior to pouring the slab, the base is first mounted to the decking or forming surface that underlies the slab. After certain other pre-pour items have been installed over the decking, the sleeve is then plugged into the base's socket and supports the anchor bolt vertically. The combined function of the sleeve and base is to fix the bolt in position during both the pour and cure phases of the slab, so that the bolt is held vertically with its threads projecting above the slab's top surface. The sleeve has openings through its sidewall that are sufficiently large to allow wet concrete the bolt's shank within the sleeve. Also, the sleeve is adapted to provide vertical adjustability of the anchor bolt's height relative to the decking, thus providing a way to accommodate bolt height to variations in slab depth.
