Armature is a set of elements used in reinforced concrete structures. It is mainly used in order to reduce the load on the design, which leads to its stretching, but it is possible to use it for opposite purposes — in overloaded zones subject to compression. Metal reinforcement of concrete increases the reliability of the entire structure, since the metal has high strength and resistance to temperature changes. Basically, when reinforcing, flexible reinforcement is used — frames, welded nets, as well as steel rods — but in some cases, hard reinforcement (I -Taurus and Channel) is used).
The reinforcement can be divided into categories according to a variety of criteria:
On the shape of the surface, the products are divided into smooth and corrugated. In the first case, the section is constant, in the second — periodic.
By the method of manufacture, the reinforcement is divided into hot rolled and cold. These varieties are also called rod and wire reinforcement.
The orientation of the reinforcement in the structure can be transverse or longitudinal.
Reinforcement can be strengthened using thermomechanical treatment or by drawing.
According to the conditions of use, the reinforcement is divided into intense and unnecessary.
In addition, the reinforcement is divided into several subcategories for its intended purpose. The main varieties are installation and working reinforcement. There is also an anchor and distribution reinforcement, it is also constructive.
The working reinforcement takes on the main loads on the design and is the main supporting element of the frame.
The mounting reinforcement takes on very little load and is mainly responsible for the correct location of the load -bearing elements.
Constructive (distribution) reinforcement) is responsible for the integrity of the entire reinforced concrete structure. Assumes «additional» loads. It is often installed in those places in which the greatest concentration of voltage is achieved.
Anchor reinforcement are embedded parts.
The most common brands of reinforcement most widely used reinforcement brands are now A1 reinforcement and A3 reinforcement.
Is there a difference between these types and if there is, then what is it?
A1 reinforcement is a truly universal building material. It is produced mainly from high -quality carbon steel, characterized by high strength. Sometimes this type of reinforcement is made of wire made in the method of cold hood. A1 reinforcement is used in many areas of industry. It is most widely used in construction and in mining.
A distinctive feature of the A1 reinforcement is the stability to almost any conditions.
It is not susceptible to corrosion, the effects of caustic substances, moreover, it has high heat resistance. Such armature can be used even in the most extreme conditions and have no doubt about its reliability.
A3 reinforcement, unlike the A1 type, is used mainly when creating reinforced concrete structures. It is made of high -quality reinforcing steel — both high -carbon and low -carbon. The reinforcement may also include elements such as titanium, silicon, etc. D. It has a higher elasticity than the A1 reinforcement is better welded, but not all the conditions withstands.
Thus, only with the help of specifically formulated goals and objectives can you determine which type of product is more suitable for you — A1 reinforcement or reinforcement A3. The price here is not a decisive factor.
