Definitions

  • the present invention relates to a formwork panel, especially for concrete formwork, comprising a plate-shaped core, which has wooden components and a has front and rear side surfaces, one Support structure in which the plate-shaped core is stored is, and at least a layer of wood flour-filled Polypropylene (HMPP), which at least on one side of the plate-shaped core is attached. It also affects the use of a composite panel comprising one plate-shaped core and at least one layer of HMPP as Formwork panel. Furthermore, the invention relates to the Use an HMPP layer to improve Nailability of a formwork panel.
  • HMPP wood flour-filled Polypropylene

Form the formwork panels thereby the negative form of the later concrete surfaces. Your basic technical functions are the formation of a dense Area as well as the immediate absorption of fresh concrete pressure.
  • the formwork panels guide the surface-acting Fresh concrete pressure in the support structure, which is usually from formwork beams with tapes in the wall or Yoke beams and support stands or scaffolding in the ceiling consists.
  • the formwork panels are considerable bending and Exposed to shear stresses, but may deform only to a limited extent. In addition to these static The formwork panels must also be exposed to rough conditions Construction site use considerable mechanical and chemical Resist stresses and weather conditions.
  • Formwork panels should also be easy to nail different parts, e.g. Cutout boxes for Windows and doors, electrical and other installations, Anchoring points, etc., simply by nailing on the To be able to attach the formlining.
