Abstract: A mounting arrangement for securing signs at select positions along the length of a concrete barrier is provided by forming a longitudinally extending groove within one side of the barrier and slideably positioning a bolt within the channel so that the bolt is captured within the channel for longitudinal movement relative thereto and extends through the groove and to the exterior of the barrier. The bolt extends through a sign support on the exterior of the barrier. A nut engaged with the bolt draws the sign support into secure engagement with the exterior surface of the barrier.

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.
