Elements of building construction: reinforced concrete lintels

Looking at the ancient monuments of architecture, one can notice that for them certain elements, which are often used now, were not used. For example, builders have not used reinforced concrete lintels before. Instead, brick was used in construction.

It should be noted that floor beams (reinforced concrete) greatly facilitate the process of building construction. Of great importance are the operational properties of the material. The reinforced concrete lintel can withstand a relatively large weight. This is especially significant when building several floors. Since 1802, reinforced concrete began to be used in construction. This material gradually became one of the main in the construction of multi-storey buildings.

Reinforced concrete lintels are structural elements that are very popular today. Most often, these elements are used in the construction of openings (window and door). In addition, reinforced concrete lintels are used in other cases. For example, in the construction of vineyards, fences, fences.

Reinforced concrete lintels are highly resistant to environmental influences, in particular, to precipitation, as well as aggressive biological and chemical substances. Among the advantages of these structures, their high strength and fire resistance should be noted. Equally important is the relatively affordable cost of the elements, as well as the simplicity of their installation.

Reinforced concrete lintels are erected simultaneously with the construction of walls and can be ready-made factory or monolithic. The latter is poured directly on the spot. In construction, reinforced concrete factory-made lintels, however, are more popular. They have several advantages. In particular, prefabricated factory elements are installed directly in place of the opening. This significantly saves construction time, due to the fact that workers are not idle. It is also important that factory products undergo special quality control, since they belong to the category of load-bearing structures. However, despite the rather strict control of the release of elements, improper installation may violate the operational properties of the products.

Although there are various design methods, some general rules have been adopted. However, in some cases, elements are used whose load bearing exceeds the planned one. This choice is valid. You can not select jumpers with less than planned bearing load.

Before installing the elements, the supporting parts of the walls must be checked (this is done using the level). When constructing jumpers, it should be remembered that when designing and creating structures, one direction of load is taken into account. In this regard, they must be installed in a certain position with respect to other structural elements of the wall. This not only makes the appearance of the building more aesthetic, but also increases the stability of the structure.
