Method of increasing rigidity of solid bodies used in e.g. construction industry

摘要

The rigidity increasing process comprises making the body from a pressure-resistant material (1) and a traction-resistant material (4), connected by a three-dimensional grid-like system. Some of the toothed webs (3) of the grid are integrated into the pressure-resistant material and the rest into the traction-resistant material. Under external load, their upper region presses against the pressure-resistant material, while the lower toothed region is at the same time edged into the traction resistant material to produce a lever action between the two materials.
