A single wythe of brick that is not structural in nature is referred to as a masonry veneer. A multiple-wythe masonry wall may be composed of a single type of masonry unit layered to increase its thickness and structural strength, or different masonry units chosen by function, such as an economical concrete block serving a structural purpose ...
A leaf is as thick as the width of one brick, but a wall is said to be one brick thick if it as wide as the length of a brick. Accordingly, a single-leaf wall is a half brick thickness; a wall with the simplest possible masonry transverse bond [definition needed] is said to be one brick thick, and so on. [21]
The infill wall has the unique static function to bear its own weight. The infill wall is an external vertical opaque type of closure. With respect to other categories of wall, the infill wall differs from the partition that serves to separate two interior spaces, yet also non-load bearing, and from the load bearing wall.
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.
A cavity wall is composed of two masonry walls separated by an air space. The outer wall is made of brick and faces the outside of the building structure. [6] The inner wall may be constructed of masonry units such as concrete block, structural clay, brick or reinforced concrete. [6] These two walls are fastened together with metal ties or ...
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.
A water table is a projection of lower masonry on the outside of a wall, slightly above the ground, or at the top of a wainscot section of a wall (in this case also known as a sill). It is both a functional and architectural feature that consists of a projection that deflects water running down the face of a building away from lower courses or ...
Modern masonry still uses core and veneer walls; however, the core is now generally concrete block instead of rubble, and moisture barriers are included. [2] Often such walls end up as cavity walls by the inclusion of space between the external veneer and the core in order to provide for moisture and thermal control.
