ABSTRACT:
A masonry lintel having a concealed spine which spans between piers to either side of an area to be arched and supports masonry bricks through means of horseshoe shaped plates which ride on the spine. The bricks are supported on the spine by stitching rods which extend through apertures in the plates and the bricks. The plates are received in the grouting space between the bricks and, in the finished lintel, are grouted over to be completely hidden from view. Variations in the relative positions of the piers and the width of bricks used to construct the lintel are accommodated by adjustable supports between the spine and the piers which enable the position of the spine relative to the piers to be selectively adjusted. In the embodiments employing multiple generally parallel spines, these supports provide for adjustable spacing of the spines. Center supports for the spines are adjustable both vertically and horizontally to accommodate various structural design parameters.
