Fundamental beams: application features

When constructing production facilities, separate supports are used. For the erection of walls, foundation beams are used, which allow the entire frame of the foundation to be fixed. Positive moments in their application are increasing the collection of the building, facilitating the construction of underground communications within the structure.

Beams are necessarily used in those constructions where the brickwork is present in the part of the socle and walls. In buildings with hinged panel walls, these bases do not carry loads.

The foundation beams, which are used for installation in the columns of the columns, are longer than the materials located at the top of the base of the building. The difference in size is one meter.

When building objects, the foundation is installed on posts called support pillows. If the base of the building is large enough, special niches are created in its upper part. They mount standard foundation beams, which do not shorten. There are also truncated varieties, which are shorter than typical ones by half a meter. They are usually used in building cells and attached to the temperature transverse seam.

Also beams are used in the construction of many frame structures. The main purpose of their installation is the installation of external walls, which are placed on this base. In this case, the beams are laid on the edge of the foundation, on the concrete solution. On the top of the products it is necessary to perform waterproofing. For this, sand solutions with cement are usually used.

Fundamental beams at the place of destination belong to several groups. The first include products that are mounted near the outer walls, they are also called "walled". The second group includes beams, installed between the columns in such a way that their axes are aligned (connected). Ordinary beams are used between two types of plates: wall-mounted and bonded. The fourth group includes ribbed products, which are also called "sanitary-technical". They have a thickness of 22 centimeters.

Today in the construction of both industrial buildings and public foundation beams play a special role. Calculations show that the cost of these materials is about two and a half percent of the total sum of the building.

The beams are made of concrete of M200-300 grades , which fully comply with the requirements of all state standards. These products allow to ensure optimum perception of the load from the walls. The materials are made with different cross sections. For example, with T-shaped or trapezoidal.

In many cases, the foundation beam from above has a flat area with a certain size, which depends on the types of wall material. The lower part of the products is presented in the form of a truncated cone. This design primarily reduces the cost of production of these building materials. At the same time, the quality of the structure does not suffer, and the perceived loads do not decrease.
