Definitions

  • the invention relates to structural members and, more particularly, to structural members, such as building boards used in construction and scaffolding, suited, fo carrying loads.
  • Structural members are used in building and construction industries to carry relatively heavy loads. They usually consist of load-supporting boards made of wood or metal. These boards must be produced with high quality standards since they carry heavy loads and the potential for serious accidents is substantial. Wood boards are usually simply formed by sawing planks to the desired size. Wood boards however suffer from the adverse affects of the weather and vary quite considerably in their strength, particularly in the case of boards including knots in the wood. Metal boards are advantageous since they are waterproof. However, they are usually made of steel sheets to obtain an adequate stiffness which considerably increase their weight. Moreover, their modulus of resilience is relatively low. Preferably, the structural members for building and construction industries must be relatively light, insensible to weather stresses, and have a high cantilever strength and stiffness.
  • US Patent No. 6,431,316 describes a scaffold plank including a rectangularly configured main body fabricated from a recycled/recyclable plastic material.
  • the main body is provided with reinforcement webs extending longitudinally and diagonally in the main body. Since the scaffold plank includes diagonal reinforcement members, it cannot be manufactured with low cost manufacturing methods such as extrusion. This increases the manufacturing cost of the plank. Moreover, the mechanical properties of the plank cannot be modified in accordance with the user's specific needs.
