摘要:
An improved corbel includes a first tier having first blocks (48) and a second tier (50) having second blocks (50e, 50i). Each of the first blocks (48) includes a first aperture (72) extending through the block (48) from a first surface to a back surface and a second aperture (74) formed through a top surface of the block (48), extending into the first aperture (72). The first blocks (48) are arranged on a substantially planar surface to align the respective first apertures (72) to define a first passageway (32). Each of the second blocks (50e, 50i) includes a third aperture (80) extending through the second block (50i) from a top surface to a bottom surface. The second blocks (50i) are disposed above the first tier to align the third aperture (80) of each of the second blocks (50i) with the second aperture (74) of the first blocks (48) to form a second passageway (30).
