Solid brickwork is made of two or more wythes of bricks with the units running horizontally (called stretcher bricks) bound together with bricks running transverse to the wall (called "header" bricks). Each row of bricks is known as a course. The pattern of headers and stretchers employed gives rise to different 'bonds' such as the common bond ...
A "face brick" is a higher-quality brick, designed for use in visible external surfaces in face-work, as opposed to a "filler brick" for internal parts of the wall, or where the surface is to be covered with stucco or a similar coating, or where the filler bricks will be concealed by other bricks (in structures more than two bricks thick).
This is the simplest arrangement of masonry units. If the wall is two wythes thick, one header is used to bind the two wythes together. [3] Header course: This is a course made up of a row of headers. [1] Bond course: This is a course of headers that bond the facing masonry to the backing masonry. [1] Plinth: The bottom course of a wall.
Header bond has courses of headers offset by half a brick. Stack bond consists of bricks laid directly on top of one another with joints aligned. This is a weak bond and is likely to require reinforcement. Garden wall bond has three courses of stretchers then one course of headers. Sussex bond has three stretchers and one header in each course.
The oldest extant brick building above ground is possibly Songyue Pagoda, dated to 523 AD. By the end of the third century BC in China, both hollow and small bricks were available for use in building walls and ceilings. Fired bricks were first mass-produced during the construction of the tomb of China's first Emperor, Qin Shi Huangdi.
Because the masonry veneer is non-structural, it must be tied back to the building structure to prevent movement under wind and earthquake loads. Brick ties are used for this purpose, and may take the form of corrugated metal straps nailed or screwed to the structural framing, or as wire extensions to horizontal joint reinforcement in a fully masonry veneer or cavity wall.
