The consequences of errors when knitting reinforcing bars

In home construction, the creation of reinforced concrete structures is often required. For example, such work is carried out when pouring the foundation under the house or concrete floor screed. Reinforced concrete is much stronger. But the ligation of reinforcing rods must be performed according to the accepted technology.

Usually in home construction, the labor of lay workers is used, which often do not comply with the necessary requirements for the installation of a reinforcing cage. A competent frame is an indispensable guarantee of a long service life of a reinforced concrete product. The design project involves a number of important elements:

• List of necessary parts;
• Production of drawings, according to which each reinforcing bar has its own place;
• Determining the place of the frame in a reinforced concrete screed or formwork;
• Data for the creation and installation of fittings (their size and quantity).

Key mistakes and their consequences

Lack of competence and lack of experience often lead performers to errors when creating a reinforcing cage. If you do not take into account the most serious errors, there are several basic minor ones:

1. Not very strong frame, which loses its shape under the influence of the mass of concrete.
2. Error with the size of the protection layer.
3. An unauthorized decision to change the reinforcement parameters in order to strengthen it.
4. Incorrect or inaccurate arrangement of the main working rods.
5. Incorrect manufacture of frame elements not provided for by the project. These include bends and clamps.
6. Errors in determining the strength class of reinforcement.

Sometimes errors can be managed to notice and correct yourself. For example, when the frame is weak, it shifts under the weight of the concrete.

The protective layer is often incorrectly set, but it is difficult to notice this on time due to the location of the main reinforcement rods close to the concrete surface.

At first glance, insignificant errors have a significant effect on the properties of the material. Such errors can lead to negative consequences:

• Destruction of the foundation or concrete screed;
• Deformation of the house or the appearance of cracks in the walls;
• The formation of cracks in a reinforced concrete slab.

Serious violations can lead to the complete impossibility of further operation of the facility or its dismantling. In the best case, the reinforcement will have to be strengthened and redesigned. This leads to a significant increase in the cost of construction.

The main way to prevent such errors is to involve qualified specialists in the work of knitting reinforcing bars and constantly monitor them in the process.
