A corbel arch (or corbeled / corbelled arch) is an arch-like construction method that uses the architectural technique of corbeling to span a space or void in a structure, such as an entranceway in a wall or as the span of a bridge. Architects also should know the approximate size and location of the brick cores. Concrete, stone and metal caps and copings can be installed in relatively long pieces, thus requiring less joints than do those made from brick. 217 0 obj <>stream CONTACT US. corbelling The size of ... the brick manufacturer has confirmed, in writing, that the brick is suitable, taking account of the brickwork detailing and the particular exposure of each rendered element.
