weir, fish trap, beam, girder
梁 centers on a horizontal structural support: a beam or girder in construction. The weir and fish trap senses extend from the idea of a barrier or framework placed across water.
梁 combines 木 (wood) with a phonetic component that also suggests a bridge-like structure. The character originally referred to a wooden beam or bridge, and the water-related meanings likely developed from the idea of a barrier across a stream.
The bottom 木 is wood, and the upper part looks like a framework with water 氵 and a blade 刀. Picture a wooden beam spanning a stream, with a blade-like weir cutting through the water to trap fish.
For リョウ, imagine a long row of wooden beams lined up: row -> リョウ, and each beam supports the structure.
