Beam and crossbar formwork is a special type of construction equipment for pouring concrete surfaces. Construction companies use this type of formwork during construction:

  • columns
  • bridges
  • walls
  • foundation
  • dams
  • pools
  • water treatment facilities
  • parking lots
  • tunnels
  • stadiums
  • wells,
  • pits
  • straight and rounded concrete surfaces.

Beam-beam formwork is used for the construction of complex and simple concrete forms. As a rule, it is necessary to use lifting equipment for installation. In the assembled form, the already mounted beam-crossbar formwork is lifted using a crane, for which the formwork is equipped with crane loops.

The main nodes of the beam-crossbar formwork are:

  • beams
  • crossbars
  • plywood panels
  • struts
  • brackets
  • fasteners.

The beams are made of wood material, provide the shape of an I-beam, which is suitable for fastening crossbars and plywood panels. The I-beam design provides high beam strength by correctly distributing the load and pressure of the concrete mass. Beams are often equipped with metal tips, or use another material. This ensures the durability of the part and less wear during operation.

The crossbar is made of steel, which has great mechanical strength and hardness, which is required for work in difficult conditions of monolithic construction. The surface is painted to protect against corrosion, which destroys the metal and reduces the service life. Steel crossbars are fixed relative to the beams perpendicularly and perform a fixing, holding function.

How many beams do you need per beam?

The number of crossbars is calculated based on the height of the beams. From the bottom, 35-45 cm recede and then for each 1.0 - 1.4 m of beam height, one crossbar is needed.

There is a certain formula for calculating the number of beams and crossbars. For a crossbar 1.1 m long, 4 beams are required, 1.2 m long - 5 beams, 1.45 m long - 6 beams, etc.

The number of beams and girders for casting concrete columns of square section is also specially calculated.

If the height of the concrete surface is higher than the height of the existing beam, extension is applied. Steel plates make it possible to connect two beams into one. It is also possible to connect two crossbars using an insert and wedges. Therefore, a technical project of almost any complexity can be solved using beam-beam formwork.

This construction equipment is an ideal formwork for the construction of monolithic structures and walls, very often used in urban construction.

Main advantages:

  • Many cycles of use - formwork can be used on one site for the construction of the foundation, and the colonnade, and walls, as well as other reinforced concrete surfaces.
  • Compact in disassembled form, which makes storage and transportation extremely easy. I-beams are conveniently stacked one on top of the other.
  • Beam and crossbar formwork adapts to almost any project.
  • After using this type of formwork, there are no joints or seams on the concrete wall.
  • Simple installation and dismantling, but with the condition of using a crane.
  • The modular construction of the formwork allows you to build complex in shape objects.
  • High strength formwork elements and the entire structure. The use of beams and crossbars makes it easy to withstand the pressure of concrete on the shield.
  • Profitability due to inexpensive materials from which the main components of the construction of beam-girder equipment are made.
