Important Terms in Brickwork

Bond

The arrangement of the bricks in successive courses to tie the brick work together both longitudinally and transversely. The arrangement is usually designed to ensure that no vertical joint of one course is exactly over the one in the next course above or below it, and there is greatest possible amount of lap.

 


Bed Joint

Horizontal joint in brick work or masonry.

 

Closer

Any portion of a brick used in constructing a wall, to close up the bond next to the end brick of a course.

 

Coping or Weathering

The cover applied over or the geometrical form given to a part of structure to enable it to shed rain water.

 

Corbel

A cantilever projecting from the face of a wall to form a bearing.

 

Cornice

Horizontal or ornamental feature projecting from the face of a wall.

 

Course

A layer of bricks including bed mortar.

 


Cross joint

A joint other than a bed joint normal to the wall face.

 

Efflorescence

A powdery incrustment of salts left by evaporation. This may be visible on the surface or may be below surface. In the latter case, this is termed as crypto Efflorescence.

 

Header

A brick laid with its length across the wall.

 

Indenting

The leaving recesses into which future work can be bonded.

 

Jamb

The part of the wall at the side of an opening.

 

Joint

A junction of bricks.

 

Jointing

The operation of finishing joints as the masonry work proceeds.

 


Pier

A thickened section forming integral part of the wall placed at intervals along the wall primarily to increase the stiffness of the wall or to carry a vertical concentrated load. The thickness of a pier is the over all thickness including the thickness of the wall, or when bonded into one leaf of a cavity wall the thickness obtained by treating this leaf as an independent wall

 

Pillar

Pillar means a detached masonry support. This can be rectangular, circular, elliptical etc. In case of rectangular pillar, the breadth shall not exceed three times the thickness and thickness itself shall not exceed more than thrice the length of brick.

 

Quoin

An external corner in brick work, the term may also denote the brick used to form the quoin.

 

Scaffolding

A temporary erection of timber or steel work used in the construction, alteration, demolition or repairs of a building to support or to attend of the hoisting or lowering of workmen, their tools and materials. Scaffoldings are of two types, namely single and double scaffoldings. Single scaffolding consists of a row of verticals connected to wall by horizontal supported on and tied to the structure. Double scaffolding consists of two rows of verticals secured or leashed together with horizontal and diagonal bracings forming essentially a structure independent of the building. It may also connect to the structure at convenient points for the sake of better stability.

 

Sill

A brick work forming the lower boundary of door or window opening.

 

Spandrel

The space between the haunches and the road decking of an arch.

 

Strecher

A brick laid with its length in the direction of the wall.

 

String course

A horizontal course projecting from a wall usually introduced at every floor level or windows or below parapet for imparting architectural appearance to the structure and also keeping off the rain water.

 

Templet

A pattern of sheet metal used as a guide for setting out specific section and shape.

 

Toothing

Bricks left projecting in alternate courses to bond with future work.

Wall joint

A joint parallel to the wall face.
