Types and application of beams for formwork

In its design, the 2-way beam consists of 2 parallel shelves and the rack separating their. Shelves are mainly made of softwood wood, and racks – from glued timber or plywood, there are products from other materials. When installing beams are mounted with each other with a special joint-groove compound and additionally misses adhesive composition. Of these, systems are assembled by various complexity and configurations, so before installation is very important to study the types and methods of using beams for formwork.

The most popular domestic production beams are called BDK-1. Shelves for them are made of pine or spruce, less often of hardwood wood. For the production of racks, they use a special fan of birch veneer, which is well withstanding the impact of dampness and moisture.

European-made beams are 2 main types:

  1. Uni – The rack is made of plywood, and the shelves made of coniferous wood, preferably ate;

  2. Opti – Shelves are also made of wood coniferous rocks (spruce or pines), and a LVL-timber from glued veneer is used to produce racks.

There are also other types of products.

  • Metal and plastic beams. Most often used when erecting formwork for filling the foundation, as well as when creating overlaps.

  • Solid rigleels and beams with different sections (rectangular, brazers, lattice). Universal products, among professional builders are considered more durable than Standard Wooden Divine.

  • Aligning 2-way beams. Apply to change or set the correct form of formwork design. In addition, used for alignment of walls, corners, overlaps, partitions.

Almost all types of beams, regardless of the manufacturer, have yellow. The level of humidity ranges from 9 to 13%, and the density of products is 460-680 kilograms per cubic meter. Weights of the standard meter of the standard wooden beam of Russian production – 6 kilograms, European – from 5 to 5.5 kilograms.

Materials manufacturing

Production material is selected depending on the type of construction, the type of construction work and the conditions of their execution. As a rule, specialists determine the necessary modification of the profile individually, since each material has different specifications.

Make beams for formwork from different materials.

  • Wood – budget universal option that is suitable for many types of work. Formwork systems made of wooden beams give a minimal shrinkage, fully meet all basic standards and requirements. In the process of making wood, a special processing passes – it is carefully dried and soaked with special chemical compositions.

  • Metal. Such products are an order of magnitude more expensive, but differ in high strength and reliability. Metal beams are not subject to deformation even with long use, have more application cycles. However, due to high cost, only large construction organizations are most often used when performing large-scale work.

  • Aluminum. Basically, aluminum is made only by leveling type beams. Convenient in montage and have a light weight, despite this, have a very high stock of strength, reliable and durable. The only minus of aluminum products – when breakdown and deformation, they are not subject to repair and restoration.

  • Plastic. Plastic 2-way beams are used, as a rule, only private developers and small brigades – to build auxiliary structures and utility buildings in the household, during the construction of country houses or cottages. Plastic beams are more expensive than wood, but they are more convenient in installation – they are lighter, they are mounted faster, not subject to deformation. Monolithic structures created by plastic frost faster.

Regardless of the material, all foreign beams are manufactured with a longitudinal section, and when installing it is assumed to contact at least two reference points.

Scope of application

Loop and other types of beams are used not only to create formwork systems, but also for the construction of various building structures in the form of walls, partitions, overlaps or columns.

The beams for formwork are used for many types of general construction works, systems from these elements are used when erected:

  • residential buildings;

  • auxiliary buildings in the sub-economy;

  • large and small industrial facilities;

  • warehouses and hangars;

  • tunnels and bridges;

  • Different Design Configuration Designs.

The wide popularity of their application is explained by the convenience of transportation and installation, the length of use, versatility. The use of beam allows you to get smooth and smooth surfaces, guarantees a high level of carrier capabilities of the collected design.

Mounting

When assembling formwork structures, all technological requirements should be accurately observed, as well as take into account the rules of installation work depending on the type of product and the material of its manufacture.

The procedure for performing actions when installing the formwork system from the beams:

  • A platform is prepared – the garbage is removed and the surface of the site is leveled;

  • Supporting tripods are installed – the distance between them will depend on the complexity and weight of the entire system, but in any case it should not exceed 1.5 meters;

  • Racks with holders, which will be directly attached to the beams;

  • First longitudinal riggers are mounted, and on top of them are transverse, while it is important to withstand the same installation step – 50-60 centimeters;

  • Vertical side shields are fixed on the beams, the grooves between the individual elements are closed with a polyethylene film;

  • The horizontal shields are stacked, with the help of the construction level, their plane is adjusted and aligned.

When installing it is important to take into account that each design element is designed for a certain load. During the fill of the concrete mix, non-compliance of the rules can lead to deformation and failure of the entire system.
