Abstract: A headed loop anchor (10) comprising a “U” shaped section having parallel spaced legs (11 and 12) and a looped adjoining section (13), the free ends (14 and 15) having heads (16 and 17). The headed loop anchor is formed by bending and then forging the head from the legs so the anchor is an integral unit. In use, the headed loop anchors are positioned in parallel spaced relation so that the looped sections (13) project from a slab so that a suitable connector may be used to hook over the loop sections (13) in order to connect adjacent concrete sections together.

Abstract: A concrete construction (10) comprises a first slab (11) and a second slab (12), there being a gap (13) between the slabs. The gap (13) may be formed by removing form work or it may be an expansion joint or a crack induction joint which requires a surface finish. An expandable gap filler support member in the form of a spacer (14) is inserted into the gap before application of a caulking compound as filler. The spacer (14) is an extruded strip which has two opposing Y shaped sections (15) and (16) set back-to-back and formed as a symmetrical unit having divergent flanges (17), (18), (19) and (20) which are able to flex so that the spacer (14) may be inserted in the gap (13). As the slabs (11) and (12) expand and contract the arms (17), (18), (19) and (20) will flex with that movement. In the case of gaps of greater depth multiple spacers may inserted one atop the other.
