Coordination dimensions are the actual physical dimensions of the brick with the mortar required on one header face, one stretcher face and one bed. Working dimensions is the size of a manufactured brick. It is also called the nominal size of a brick. Brick size may be slightly different due to shrinkage or distortion due to firing, etc.
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 (with every sixth course composed of headers), the English bond, and the Flemish bond (with alternating stretcher and header bricks present on every course). Bonds can differ in strength and in ...
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.
Wall framing in house construction includes the vertical and horizontal members of exterior walls and interior partitions, both of bearing walls and non-bearing walls. . These stick members, referred to as studs, wall plates and lintels (sometimes called headers), serve as a nailing base for all covering material and support the upper floor platforms, which provide the lateral strength along a
Two basic categories of bricks are fired and non-fired bricks. Brickwork – is masonry produced by a bricklayer, using bricks and mortar. Typically, rows of bricks—called courses— [21] [22] are laid on top of one another to build up a structure such as a brick wall.
In conventional steel frame building systems, the vertical force resisting steel frame system is supported in the lateral direction by steel bracing or an equivalent system. When the architectural plans call for concrete masonry walls to be placed within the frame, extra labor is required to ensure the masonry fits around the steel frame.
The term fine adjustment screw typically refers to screws with threads from 40–100 TPI (Threads Per Inch) (0.5 mm to 0.2 mm pitch) and ultra fine adjustment screw has been used to refer to 100–254 TPI (0.2 mm to 0.1 mm pitch). These screws are most frequently used in applications where the screw is used to control fine motion of an object.
The channel can be a hot-rolled or a cold-formed steel shape in which a T-shape screw is placed in order to transfer the load to the base material. Headed stud: consist of a steel plate with headed studs welded on (see also threaded rod). Threaded sleeves: consist of a tube with an internal thread which is anchored back into the concrete.
