Construction without Mortar Joints
Construction Design Dimensions
The rough framing dimensions of length, width, and height are given in multiples of 12.5 cm.
- Overall dimensions include height of columns, building length, building width.
- Add-on dimensions may include sizes of recesses or projections.
- Inside dimensions, also known as clear dimensions, include door and window opening sizes.
The DIN 4172 standard specifications titled “Dimensions in Construction (Maßordnung im Hochbau)”, differentiate between two types of construction methods:
Masonry without mortar joints is a method of building without using vertical mortar joints (head joints). Interlocking brick is used in this case; the brick is about 2 mm (width of groove) shorter than the rough dimensions (for example, the size of the tongue-and-groove brick is significantly smaller than other types of brick). This makes it easier to keep to the required tolerances.
