Masonry

Masonry walls - is a construction, consisting of stones laid on the mortar in a certain order. Bricklaying takes the load on its own weight and other structural elements, based on the clutch, and applied to them loads.

When construction of buildings and structures used the following types of masonry: brick, ceramic stone, made of concrete, brick or ceramic stones from the natural rough-stone, artificial large blocks of irregular shape; mixed (Butova Lined with brick masonry, from cast stone, lined with brick, brick, faced with hewn stone), concrete, lightweight masonry of brick and other materials.

Masonry carry on limestone, mixed, cement-lime and cement mortar, as well as cement-clay mortar, in which the clay serves as a plasticizing additives. The type and brand of the solution point in the working drawings. The system of dressing - this is the order of laying bricks (stones) in a batch to each other in accordance with the rules of cutting masonry.

There are dressing vertical, longitudinal and transverse seams. Longitudinal seams bandage to masonry not rozshatyvalis along the wall at a thin walls and that the stresses in the brickwork of the load variously distributed across the width of the wall.

For example, if the wall thickness of 1

Banding of the transverse joints needed for the longitudinal connection between the individual bricks, which provides load distribution on the adjacent areas of masonry and monolithic wall with erratic rainfall, temperature deformation, etc.

Banding of the transverse joints serve spoons and widths, and longitudinal - widths. Brick masonry walls has the banding system: single-strand (chain), multiseriate, trohryadnaya.

Performance depends on how masons laying bricks and ability to apply them when working on different solutions. Bricklaying layers are three ways: upritisk, uprisk and injection with the trimming of the solution, and back filling - in polunatisk.

If you need to split the brick along, you will first cause a slight stroke on 4 of its planes, and then a strong and short stroke of stumps at the end of the line of bricks divide it into the desired part. Brick cut and edge trowel.

Technical requirements for the job

Masonry walls and other structures perform in accordance with the rules of implementation and acceptance of works, compliance with which ensures the required strength of the erected designs and high quality work.

In the process of working mason should ensure that, as used brick and mortar specified in working drawings, to verify the correctness and quality of dressing masonry joints, vertical, horizontal and straight surfaces and angles, the correct installation of mortgage details and links, the quality of surfaces masonry, as well as the quality of the materials used.

In dry hot and windy weather before laying bricks to moisten with water to a solution is better mated to a brick and normally hardened. In breaks in the upper row of masonry mortar is left uncovered. Clutch after the break must begin with the irrigation water surface previously laid masonry. This is particularly important for the clutches in seismic areas and those. This requirement is dictated by the fact that the dry bricks after laying on solution quickly sucking away the water, decreasing water content in it and the strength of the solution decreases.
