General Indications for Load Tables

The load is rated within the limits of the elastic stretch of the material (permissible elastic limit). The deflection of the material is limited to 10mm. For higher values, the load table must be newly calculated.

For neighbouring panels, each deflection must not exceed the value of 4mm, otherwise the panels must be screwed together. The difference between the values of two neighbouring panels must not exceed 4mm.

In practice we are confronted with the following types of load :

  • Uniformely distributed load - vertically active against the panel surface [kN]
  • Single load - active over the total width of the panel and uniformely distributed over a basic area of B x 20cm. In this case, the load must be calculated in the most unfavourable position.
  • The values for the load and the loaded area are calculated due to DIN/EN/ISO1055 - page 3 or DIN/EN/ISO1072.
  • For example : for passable constructions the total wheel load can be calculated from single loads.

The permissible load of a construction can be increased by the installation of additional supports - up to circa 37%.

The permissible load of a construction can be increased by screwing together of two neighbouring panels - up to circa 23%.
