SLIPFORM STONEMASONRY Meaning and
Definition
-
Slipform stonemasonry is a construction technique used to build vertical structures, such as walls or towers, made primarily out of stones or concrete. This method involves pouring and forming a continuous vertical concrete or stone structure using a movable formwork system. It is commonly used in the construction of tall structures with a consistent shape and design.
The process begins by setting up a rigid formwork, usually made of steel or wood, which acts as a mold for the structure. Vertical reinforcing bars (rebar) are placed within the formwork to provide additional strength and stability. As the formwork is elevated, concrete or stone is poured into the cavity between the formwork and the previously solidified structure. The pouring is done in stages, allowing the material to gradually set and harden.
Simultaneously with the pouring process, the formwork is raised vertically using hydraulic jacks or other mechanisms. This gradual elevation of the formwork allows the construction to progress at a steady rate, typically a few inches per hour. This continuous upward movement creates a seamless structure with an even surface and eliminates the need for horizontal joints.
Slipform stonemasonry is known for its efficiency and speed compared to traditional stonemasonry techniques. It allows for the rapid construction of tall structures while ensuring consistent quality and reducing labor costs. This method is commonly used in the construction of towers, dams, bridges, and other large-scale projects where a vertical, solid structure is required.
Etymology of SLIPFORM STONEMASONRY
The term "slipform stonemasonry" is a compound word that combines "slipform" and "stonemasonry".
The word "slipform" originated in the early 20th century and comes from the verb "slip", meaning to slide or move smoothly and continuously along a surface. In slipform construction, a formwork or mold is continuously moved or "slipped" upwards as the construction process progresses. It allows for continuous pouring of concrete or other materials to create a uniform and seamless structure.
"Stonemasonry" has its roots in the Middle English word "stonemason", which refers to a person skilled in working with stone. The word is a combination of "stone", representing the material, and "mason", indicating the craft and profession of working with stone.
Therefore, the term "slipform stonemasonry" combines these two concepts.
