In the modern construction world, reinforcing mesh is used to strengthen concrete masonry, reinforced concrete or gypsum structures, and a special type of mesh is used in the manufacture of reinforced glass.
Reinforcing mesh properties
The main technical characteristics that form the market price of the grid and affect the final choice of customers are the size of the cells and the diameter of the rods of which it consists. The rods can be smooth or corrugated with a diameter of 3-5 mm. According to the material of manufacture, the nets are divided into metal and polymer. The former serve to strengthen the cinder block, concrete or
brick walls, while the latter is not in vain called plaster or painting. Thanks to them, cracks never appear on the surface of a freshly plastered wall. But when the reinforcing mesh is missing or laid in violation of the technology, defects appear without fail. Polymer nets are impregnated with a special alkali-resistant composition that makes them practically invulnerable to the effects of sudden changes in temperature, corrosion, etc.
Specifications
High-quality reinforcing mesh has the following characteristics:
- Perfectly resists tears and sprains.
- Helps to overcome internal pressure caused by changes in air humidity and temperature changes.
- Prevents the appearance of cracks in all climatic and weather conditions.
- Increases the mechanical strength of the wall.
- The material is resistant to alkaline conditions, which is very important when you consider that almost all the solutions used in the decoration of buildings are alkaline.
- The reinforcing mesh for plaster and all other types are technologically advanced and easy to use.
Reinforcing mesh for the floor
Reinforcement of the floor is carried out in cases where the layer of concrete laid on the screed is thinner than 80 mm. Despite the apparent power and strength, concrete is a rather fragile material, especially when it experiences constant vibration and dynamic loads, so the operation of a reinforced network is entirely justified. In some cases, only some sections of the floor are reinforced or the mesh is used to reinforce the seams. Thanks to reinforcement, you can save on the amount of concrete, because this procedure allows you to reduce the thickness of the screed layer without any damage to quality.
And the nuances ...
A metal reinforcing mesh is fastened with dowels, which are staggered staggered at a distance of 20-30 cm from each other. The grid is fastened with overlapping stripes. The polymer network is glued to any putty (except for the finish). The mesh strips are also glued with an overlap or as close as possible to each other (up to 1 cm) and make sure that the joint of the mesh does not coincide with the lines of the appearance of the alleged cracks. The reinforcing mesh for the floor and walls is fixed between the layers of concrete screed or plaster. Such a network is used when insulating facade walls with mineral wool or foam. It is frost-resistant, light in weight, not subject to corrosion and easy to use.
