During the operation of buildings and structures, there is often a need to strengthen building structures, including floors. Floors to be strengthened can be of various types: reinforced concrete, monolithic, prefabricated, as well as wooden and metal.
The importance of this process is due to a number of reasons, including increased loads, changes in the purpose of the premises, extending the service life of buildings and eliminating defects that have arisen as a result of wear and tear or exposure to an aggressive environment.
The use of composite materials for reinforcement is one of the most modern and effective methods. Composites such as carbon fiber reinforced plastics and fiberglass are often used to strengthen reinforced concrete and monolithic floors due to their high strength and lightness. These materials are characterized by good adhesion to concrete, corrosion resistance and the ability to be laid on complex surfaces. Thus, the restoration and reinforcement of building structures using composites can significantly increase the load-bearing capacity and extend the service life of structures.
Strengthening wooden floors is usually associated with the replacement of damaged elements or the addition of new ones, which allows increasing their load-bearing capacity and rigidity. In the case of metal floors, reinforcement may include the installation of additional stiffening ribs, strengthening of welded seams, or building up of metal in the most loaded areas. These methods are aimed at ensuring the safe operation of buildings and preventing premature failure of structures.
