The term "line block" refers to a device or tool used in construction and masonry work. It is typically a rectangular block made of wood, plastic, or metal, with a series of grooves or notches carved into its sides and top surface. Line blocks are commonly used in pairs, with a mason's line or string stretched between them to act as a guide for the placement of bricks or stones during wall construction.
The primary purpose of a line block is to ensure the alignment and straightness of the construction work. It is often employed in projects that involve the laying of bricks, blocks, or stones, such as building walls or foundations. The grooves on the sides of the line block allow the mason's line to be easily secured and adjusted, ensuring that it remains taut and straight throughout the construction process.
By placing two line blocks on either end of a wall, the mason's line can be extended between them, creating a level and straight guideline. This helps the mason to maintain uniformity and precision when laying the construction material, resulting in a structurally sound and visually appealing finished product.
Line blocks are essential tools for achieving accuracy and consistency in construction projects, particularly those involving brickwork or stonemasonry. Their simple yet effective design makes them easy to use and highly reliable.
The etymology of the phrase "line block" can be traced back to its constituent words: "line" and "block".
1. Line:
The word "line" comes from the Latin word "linea" which means "string, thread, or line". It entered the English language through Old English "līne", meaning "rope, flax thread". Over time, the term "line" evolved to encompass various meanings like a boundary, alignment, or a series of connected points.
2. Block:
The word "block" has Old English origins, derived from the Old French "bloque" or "bloc" meaning "log" or "unworked piece of wood". It referred to a solid piece of material, particularly wood, often used for construction or as a support.
