<p>A slab (1), for laying on masonry, has lost formwork units of reinforced concrete, held on it as sidewalls (2) to provide a U-cross-sectioned gutter section, for filling with concrete, in a component for ring anchors in masonry-type structures. Reinforcing loops (3), protruding across the slab, have transverse sections (3a) embedded in it. Between these, at greater intervals than the loops, slab-shaped stiffening units (4) are joined to the sidewalls, leaving open passages in loop corner areas, for insertion of reinforcing bars (6,7) running along the gutter. The slab can have grooves (9) on the side facing the masonry. This can be prefabricated in considerable lengths, and quickly and easily mounted, without hoists.</p> |
