Definitions

  • the present invention relates to an artificial wood beam substitute, more specifically to the use of bamboo as a raw material to be used as the primary substance of the artificial wood, in which bamboo strands are laminated in random stacked parallel strips and are fused under pressure with adhesives added to create an artificial wood beam with qualities similar to that of naturally grown lumber.
  • Wood beams are generally cut from naturally grown trees. However, trees are limited in supply due to the long time necessary for a tree to reach maturity. Also, the supply of natural wood is limited by the deforestation that is now occurring in many parts of the world.
  • SUBSTIim SHEET (RULE ⁇ S) Therefore, there is a need for a natural wood beam substitute which is less expensive and at least as equally strong as natural wood beams.
  • the beam must be composed of a material which is readily available and easily replenished, and which is not a threat to the environment .
  • the bamboo would be harvested, split open, and dried in long strips ranging from 1/4 to 3/4 inch in width to approximately 5 to 20 feet in length.
  • the strands can be as short as 5 feet or less in small percentages.
  • the dried strips would have adhesive applied evenly to them and they would be aligned in parallel fashion and stacked at random length and fused under pressure.
  • FIG. 1 is a front view of the composite bamboo beam
  • FIG. 2 is an exploded view of the corner of the composite bamboo beams to show more clearly the end grain and the flat surface of the beam which is consistent on all sides and ends of the composite bamboo beams;
  • FIG. 3 is a side view of the composite bamboo beam
  • FIG. 4 is a top view of the composite bamboo beam.
  • the bamboo beam is generally designated as 10 having a core 1 and an outer surface 2.
  • the core 1 consists of bamboo segments 3 which have been bonded and compressed together to form an adhesive structure.
  • the core 1 may contain gaps 6 due to the cross-sectional shape of the bamboo segments 3 and the randomness of the stacking of the segments 3.
  • the outer surface 2 is prepared by milling the adhesive structure to a desired dimension.
  • the beam 10 is shown as having four side surfaces 4 and two end surfaces 5, defining the conventional beam dimension.
  • bamboo stalks are split open and dried in segments 3 ranging from 1/4 to 3/4 inch in width to approximately 5 to 20 feet in length.
  • the segments 3 can be as short as 5 feet or less in small percentages .
  • An adhesive suitable for bamboo is evenly applied to the dried segments 3 and the segments 3 are aligned in parallel fashion and stacked randomly. The stack is then fused under pressure until it results in a cohesive structure. When the stack has dried and is cohesive, it is milled into the desired beam dimensions.
  • suitable wood fillers 7 can be introduced into the stack before compression to eliminate any gaps 8 which may exist in the core 1 of the bamboo beam 10.
