ABSTRACT:
The invention relates to an apparatus for supporting and positioning an anchor bolt within a masonry construction block wall to allow the frame of a building to be secured or tied to the anchor bolt. Masonry construction block walls are typically constructed so that the hollow vertical cores in the construction blocks are partially aligned so as to form a hollow channel or conduit traveling down through the wall. The apparatus includes a base designed to fit within a construction block wall to provide a support to which the lower end of an anchor bolt may be attached by clips or otherwise. This allows the upper end of the anchor bolt to extend upward through the channel and above the top layer of blocks. The base also serves to plug or fill the channel formed by the cores in the blocks so as to facilitate the process of permanently securing the anchor bolt by pouring cement into the channel around the anchor bolt. The apparatus may also include an external indicator which extends external to the wall so as to provide a visual indication of the presence and location of the apparatus within the wall and other aspect to facilitate its use.
