Concrete gets into shape with formwork elements from B.T. innovation

Shutterings are hollow moulds that serve as a mould for liquid concrete. In this way, structural components made of concrete or reinforced concrete are produced as in-situ concrete. The precast plant mainly uses formwork elements. The formwork systems used there meet the highest requirements and enable precise, efficient and thus economical production of precast concrete elements.

Basically, a formwork consists of the formwork system or the formlining and the formwork beam. Which formwork or which formwork element is used depends on the type and function of the component. A formwork represents the negative element to the finished concrete component and shapes the visible surface of the concrete component through the choice of formlining. In order to be able to absorb the high pressure that arises when placing the concrete, formwork must be tight, accurately fitting, clean and stable. Prefabricated formwork elements meet these specifications particularly well and ensure results of consistently high quality (concrete formwork).

B.T. Innovation also offers special solutions for magnetic technology (shuttering magnets), with which problems in fixing the shuttering elements can be solved as simply as ingeniously. Also in the range are formwork elements with which unusual shapes and the often so problematic shuttering of curves and curves can be easily realised.

Formwork elements for precast concrete elements are used for a wide variety of applications. For example, prefabricated ceilings and walls or roof slabs are produced, as are columns and beams, reinforced concrete stairs or complete sanitary cells as prefabricated parts in the factory. The shells of system houses are also partly constructed entirely of prefabricated reinforced concrete elements. In general, different types of formwork can be distinguished for the production:

  • Panel formwork as vertical formwork is used for the construction of walls and slabs. As a rule, firmly welded frames made of aluminium or steel are used as formwork elements. Together with the formwork skin, which can be made of wood or chipboard, for example, the beams form the formwork system.
  • Beam formwork for wall, column and slab formwork can be variably assembled for any shape. The shape of the formwork, the size of the tie patterns as well as the formlining used can be adapted exactly to the requirements. The formwork elements from B.T. Innovation are ideal for the production of girder formwork, through which even complicated formwork shapes can be easily realised.

In order for a precast concrete element to be produced in accordance with DIN and economically, the formwork must meet the highest requirements and be easy to manufacture. B.T. Innovation has developed various beam shapes and elements that can be used variably for a wide range of formwork variants.

  • U-profiles with and without magnets are ideally suited, for example, as a formwork system for filigree ceilings and double walls. These profiles are particularly flexible due to the possibility of individually adapting the desired chamfers. The U-profiles are suitable for manual as well as machine use and are available in various dimensions.
  • In order to meet the individual requirements for the production of solid or sand retaining walls, balcony and podium slabs, columns, beams and other components, universally applicable formwork support systems are in demand. Here, B.T. Innovation offers various components in its MultiForm system that can be connected to each other as required and planked with the desired formwork panels. These include, for example, grouting grooves, recesses, assembly and lifting anchors and other elements.
  • The FlyFrame system made of special aluminium is similar and yet particularly light. The extremely stable beam can be used with formwork panels made of wood or chipboard.

Formwork elements are not only used in the precast plant. In order to be equipped for the special needs in the production of in-situ concrete components, flexible and easy-to-use formwork systems are also used here. The systems are suitable for slab edge formwork, as foundation formwork or also for column or ring beam formwork. The formwork of curves on the construction site in particular often poses problems for the specialist company. B.T. Innovation has developed the Syflex system for these purposes. The lightweight and robust formwork elements made of PE make shuttering easier, are extremely flexible to use and make lifting gear almost completely superfluous.

Magnet systems have long been standard in the precast concrete plant. With the help of strong magnets, the formwork elements are securely positioned on the steel shuttering tables. However, conventional magnet systems can often only be positioned with difficulty and often not at all due to the strong attractive forces. It has to be reworked with heavy equipment such as a hammer. This costs energy, material and working time. Here, B.T. Innovation has developed a novel system that can be easily customised using various accessories. Using spacers made of stainless steel or aluminium, the magnet remains inactive until it is precisely positioned and is then activated by light pressure by hand or foot. Other systems from B.T. Innovation work with integrated magnets and are just as effective and efficient to operate.
