Beams and crossbars are the linear parts of buildings and structures that perceive the load from other horizontal structures and are a core (beam) of a square or rectangular section. In construction practice, they can be made of wood, metal or reinforced concrete, and regardless of the raw materials used, it is sometimes necessary to strengthen the beams and sleepers to increase their bearing capacity and ensure the safe operation of the structures of the house.

Features of reinforcement of linear elements of construction sites.
If the rigidity of the system is reduced due to external factors or as a result of damage to the material, over time it is deformed. This leads to an active increase in tension in intact areas and even more accelerates the process of destruction. As a result, the beam does not perform the function assigned to it when designing, which brings the building or construction to the emergency state.
Wooden and metal supporting elements have a monolithic structure. In turn, reinforced concrete is a composite in which the load is perceived directly by concrete and steel reinforcement. The latter has a given direction, which is very important to know if it is planned to strengthen the beam beams.
Methods of increasing the strength of linear elements of building objects are divided into the following types:
Traditional installation of clips, clamps, inserts, tension method, pre -tense puffs. The disadvantage of this solution is to increase the mass of the system and change its appearance.
Innovation - the use of composite materials. They are easy to install and have a longer service life.
If it is planned to reinforce reinforced concrete beams, an important criterion for choosing a method is a lot of reinforcement tools, since increasing your own weight of the structure reduces the effectiveness of the result of the work. This makes carbon stripes the most economical technology for reinforcing beams, since their weight is almost insignificant.
When reinforcing superstructures, the main attention is paid to the bearing capacity of the design as a whole. Traditional technologies offer either an increase in cross section or a complete structural transformation as a solution to this problem. The first option allows you to increase the carrying capacity to 15%, the second - up to 35%. If we consider reinforcing with carbon stripes, then you can increase this indicator to 2 times. At the same time, basic geometry will remain unchanged, which is also an advantage of innovative solutions.
