Lattice beam for adjusting steel relative to formwork comprises two lattice frames attached to top rod and two bottom rods

摘要

Lattice beam (1) comprises two lattice frames (2, 3) attached to three reinforcing rods (4, 5, 6). Frames are attached to top rod (4) through end of upper loops; and frames are attached to each of two bottom rods (5, 6) upstream from end of lower loops (7, 8). Orientation of lower loops is obtained by partial bending, and allows access for stapler or welding electrode. Independent claims are also included for (a) the self-shuttering trimmer, and (b) the shuttering lintel.
