Brick walls


The advantage of such walls is their fire resistance, biological stability, durability. The service life of a brick wall over 100 years. For single-storey buildings or brick walls are laid out using the perforated brick, or of solid brick with insulation.

For low-rise buildings built of solid brick wall 38 cm more economically feasible and possible only for use in damp spaces. Calculate the thickness of the walls, depending on the ambient temperature and the material can be on the table.

Types of construction of the outer brick walls

Internal load-bearing walls and partitions one-storey houses spread from solid bricks of any brand. For walls with increased load is applied brick grade not less than “75″. Thicker interior bearing walls must be at least 25 cm

Masonry flues and ventilation used clay (red) brick with no cracks or damage. Partitions spread 12 cm thick (? bricks) and 6.5 (a brick “on edge”), with a length of 1.5 m of reinforced wire 2-3 range in height.

The space between the bricks in the longitudinal and transverse directions are filled with. Walls of brick to be placed vpustoshovku plastering, leaving the joints with the wall filled with a solution to a depth of 10-15 mm, which provides a better connection and masonry stucco layer. If the wall is not plastered, the joints in the masonry is completely filled with a solution.

When masonry walls must follow three rules:

1. The load is transmitted to the clutch must be perpendicular to the bed laying.
2. Rows of masonry should be horizontal and vertical rows with vzaimoperpendikulyarny.
3. Vertical joints in adjacent rows of masonry should not be the same that is series should be tied.

Bricklaying start on the surface, a solution aligned vertically and horizontally. Construction of the house begins with masonry corners of the building, which are carefully aligned. Between them stretched the cord, which will depend on the smoothness of the wall.

If the bricks are stacked along the long side faces the wall, or “spoon”, they form a Stretcher bond series, and short – a “poke”, the bonder series.

Types of brickwork.

Single-row chain system ligation alternates bonder Stretcher bond series. Each transverse and vertical seam of the lower number of overlapping bricks perpender top Stretcher bond series. This requires more clutch three-quarter brick and skilled mason. multilane In the system of alternating several consecutive stacked Stretcher bond series with the overlying one bonder. Masonry with continuous ligation of all seams in 4.5 or 6 rows.

If you want to increase the strength of the walls of bricks used by the horizontal reinforcement of masonry.

With the lack of frost build walls with an air gap. This type of wall is characterized by high heat-shielding properties in comparison with solid masonry at 15-20%. Facial (Stretcher bond) series have ties from the main wall by laying 4-6 series perpender number of bricks or installing metal bonds. The optimum thickness of the air gap of 50 mm, wall-420mm.

Brick walls

The walls in low-rise buildings, in order to save a brick, sometimes made of relief. This clutch is called “kolodtsevaya” with thin brick ? vertical longitudinal and transverse walls. Well educated asleep slag, expanded clay.The disadvantage of this is to reduce the strength of the wall and can be used in the walls is not heavily loaded.
