To ensure that the brick structure has servedlonger, use a special masonry net. Among other things, it allows you to reduce the consumption of the material used in the work. On the market, this product can be found in the form of cards or rolls. The sizes of masonry nets will be mentioned below, which will help you decide the choice. It is worth considering that the described material is most often used when working with hollow bricks.
general description
Reinforcing mesh is a product inwhich wire rods of different diameters are welded to each other perpendicularly. The main difference from other grids made of metal is the use of reinforcing wire, which belongs to the class of BP-1, it has a corrugated surface. Thanks to this structure, the material is cemented securely with cement and bricks.
additional characteristics
The sizes of masonry nets should be selected morebefore purchasing the goods. The latter is made of well-bending high-carbon steel. The bars in the production process are covered with PVC or zinc for more impressive strength. A number of specialists prefer a galvanized wire mesh. However, in recent years, glass fiber reinforced plastic coatings have become increasingly common, which give the product the best quality characteristics. The grid in the latter case is easier, its strength is increased, and the top layer protects against corrosion. If you want the armature to last longer, then use a product that is covered with fiberglass.
Masonry grid dimensions for brick
The sizes of masonry nets can be quitedifferent. Technical characteristics will depend on which document was used as the main one in production. These can be technical conditions or state standards. In the role of the main dimensions of the grid is the diameter of the rods, which can vary from 2.5 to 8 millimeters. The size of the holes is also important, it varies from 30 to 250 millimeters. The last in shape can be square or rectangular. Manufacturers use the following dimensions as the standard size of one single sheet: 380x1500 millimeters.
Using different mesh sizes during construction
The sizes of masonry nets were mentioned above,However, the most popular among buyers are products whose dimensions are 50x50 or 100x100 mm. It is important to take into account the diameter of the wire. Specialists most often use products whose bar thickness varies from 4 to 5 millimeters. Manufacturers to reduce the final cost of goods deliberately produce products with a more impressive size of cells. It is important when buying a mesh in the store to pay attention to the dimensions of the cells, which must necessarily correspond to the parameters declared by the manufacturer.
The difference in mesh varieties in manufacturing technology
The masonry grid for bricks, the dimensions of which were mentioned above, can differ by the manufacturing method. Thus, in the end, you can get a welded, twisted, prefabricated or woven mesh.
GOST 23279-85
The mesh grid, the size, the photo of which you canfound in the article, is made according to the above GOST. In the production process, a Class III A valve is used. Oversized products of this type with a square cell of 50 millimeters are used to reinforce masonry made of bricks. Larger cells, equivalent to 100-200 millimeters, are used to arrange floor screeding, pouring concrete, and reinforcing all kinds of solutions. The thickness of the rod also has its own meaning, so in multi-storey buildings on the lower floor it is recommended to use a grid using a wire of 5 millimeters. This is due to the fact that it has the maximum strength characteristics. On the upper floors a 4 mm grid is used. For a cottage in which two floors are supposed to exist, a 3-millimeter grid will suffice.
Dependence of the mesh size on the wall thickness
The size of the masonry grid for brickwork will bedepend on the expected thickness of the wall. Thus, for a wall of 1.5 bricks, you will need a map with the following dimensions: 0.38x2 meters. When increasing the thickness to 2 bricks, you should use a grid with dimensions equal to 0.5x2 meters. The dimensions of the mesh cells in all these cases can remain unchanged. For a brick wall of 2.5 bricks, you should use a map with dimensions equivalent to 0,63x2 meters.
Positive grid features
If you have not decided yet, is it worth reinforcingyou need to consider the advantages that the grid gives. It is resistant to the negative effects of chemicals and moisture, exhibits tensile strength, and also retains its original form even if the integrity of the structure is impaired. The material has very little thermal conductivity, serves a long time, and also shows the ability to quickly cope with the vibrations. You can rely on reliable adhesion to materials, and transportation can be done independently, without attracting additional transportation.
Features of using a grid
Masonry grids, the sizes, GOST of which werementioned above, should be stacked every 5 species. However, the frequency of laying, as well as the material consumption of the master can be changed independently, everything will depend on the purpose of construction and established standards. If a material is used in the course of work that can be corroded, it is necessary to carefully protect the rods with a layer of cement mortar. Above the surface of the masonry rods should rise by 3 millimeters.
Conclusion
If you have not decided which reinforcement methodwhen laying bricks to use, then experts advise to apply the mesh, as it takes much less time compared to other methods. With the help of sheets you can hide a fairly impressive surface area. One can not help but note the insignificant diameter of the wire, which it is possible to drown in cement mortar. This is especially important if you want to extend the lifespan of the entire structure. However, the last products of this area are covered with special substances that perform a protective function, making the material more stable and durable, and also durable.
