Walls made of perforated and checkered bricks: a), b) hollow brick walls with a thickness 1/2 i 1 bricks, c) corner, d), e) walls made of checkered bricks with a thickness 1/2 i 1 bricks.
Bindings of masonry with perforated bricks.
The perforated brick has the same dimensions as the solid brick. Depending on the shape of the holes, two types of perforated bricks are distinguished: a forklift with elongated through holes, headstock with transverse through holes. By using both types of bricks, you can make walls this way, that the holes do not appear on its face surfaces.
Perforated bricks are usually used to make partition walls. If the perforated brick is frost-resistant when wet, then it can be used to make external walls. The perforated brick is produced in two classes: 2,5 i 5,0.
In a thick masonry 1/2 all layers of bricks are stretcher bars, in the wall with a thickness 1 bricks can be all head layers.
In figure a, b, c shows the bonding of bricks in walls of different thicknesses using a carriage and head brick. In figure d, e shows the bonding of a checkered brick wall.
In practice, two types of checker bricks with dimensions are used: 250 x 120×65 mm and 250 x 120x 140 mm. Thick walls can be made of this brick 1/2 bricks and more.
