What is a single leaf wall?
A single leaf wall consists of just one layer of a building material. Single-leaf walls of hollow concrete blocks were the most common form of construction in the greater Dublin area for decades.
What does reinforced masonry mean?
Reinforced brick masonry (RBM) consists of brick masonry which incorporates steel reinforcement embedded in mortar or grout. This masonry has greatly increased resistance to forces that produce tensile and shear stresses.
What is a masonry leaf?
A masonry internal leaf system typically comprises of items such as mortar, masonry units and special shape masonry units.
What is reinforced hollow unit masonry?
Reinforced hollow-unit masonry is that type of construction made with hollow-masonry units in which cells are continuously filled with grout, and in which reinforcement is embedded. All cells shall be solidly filled with grout in reinforced hollow-unit masonry.
What does leaf mean in construction?
A cavity wall is a wall formed by an inner skin and an outer skin of masonry (sometimes referred to as ‘leaves’ or ‘wythes’ if they are a single unit wide), connected by ties, but separated by a cavity. The masonry is formed by units such as brick, stone or block.
What is a double-leaf wall?
A double-leaf wall, comprising two leaves with an air space in between them, can be very much more effective than a single-leaf wall of the same thickness. From: Encyclopedia of Materials: Science and Technology, 2001.
Why is masonry reinforced?
Reinforcement in construction is to provide tensile strength to the concrete structures. Ordinary brick masonry cannot withstand tensile stresses because bricks get pulled apart at the mortar joints, in such situations, brick masonry is reinforced by steel flats, steel bars or expanded bars.
What is reinforced brick?
Reinforced brickwork (abbreviation R.B.) is a composite structural material consisting of load-bearing brickwork masonry into which lengths of suitable metal (normally steel) are introduced and so bonded as to render the resultant composite capable of resisting not only the compressive stresses but also the tensile and …
What is single skin masonry?
A single skin of brickwork is laid on the outside of a building to form a barrier against the weather. This single skin of brickwork is not load bearing, that is, it does not support any roof loads. However, it must be strong enough to resist lateral loads from wind.
What is leaf in a brick wall?
The inner ‘leaf’ is the load-bearing wall. The outer wall acts solely as a protective layer against prolonged weathering and the two are generally connected with metal wall ties, rawl plug anchors, or stainless steel rods.
What is the difference between reinforced and unreinforced masonry?
An unreinforced masonry building has load bearing walls and non-load bearing walls, but reinforcing material, such as concrete, cinderblock or rebar, supports neither. Unreinforced masonry is typically made of bricks, hollow clay tiles, stone, concrete blocks or adobe.
What is cavity wall construction?
