Definitions

  • the invention relates to a pile construction by which piles of wood can be constructed in longer lengths than trees are growing.
  • Constructions of square wooden piles are known in which several piles are connected together by means of steel plates or profiles. Such type of connection, however, can only be used a few times for one pile and till a maximum diameter of about 50 or 60 cm, because of the lack of elasticity at the position of the connection and the high costs for such a connection.
  • An object of the invention is primary to obtain long lengths of piles while retaining the good elastic properties of wood.
  • a second object of the invention is to make it possible to use short timber pieces in their natural shape, which pieces remain by the production of wood in forest and sawmill.
  • a construction consisting of timber pieces joined in the length together by means of at least one stretch rod pulled through holes drilled in longitudinal direction in said timber pieces, in which the joining parts are sawn smooth in a plane normal to the length of said timber pieces.
  • the length of said timber pieces will lie between 100 and 200 cm, but it will be clear, that other lengths can be used as well..,
  • the strength of a pile can be influenced in a such way that the part with the greatest diameter is situated in that part of the pile which is highest loaded, such that material can be saved.
  • this hole in case of one hole being drilled in each of said timbers this hole will be positioned near the center of said timbers, while the diameter of said hole depends on the diameter of the stretch rod to be used.
  • the timbers After drilling a hole in each individual timber, the timbers are placed beside each other in such way that the part with the greatest diameter is situated in that part of the pile which is highest loaded, the diameter of the adjacent lying parts being gradually smaller.
  • stretch rod can be passed through the holes in the adjacent timbers for connecting the parts together.
  • the stretch rods can have the shape of a solid steel bar or can be shaped by steel wires or by artificial material, e.g. carbon fibers and such like.
  • a center hole in it can be filled with anti-mould and/or an insect killing and/or a rost protection medium, which medium will penetrate entirely into the material of the pile.
  • the piles shown in the figures 1, 2 and 3 are composed of a number of pieces of timber 1. Each piece 1 is provided with a longitudinal hole 2 through which runs a stretch rod 3. The ends of this stretch rod 3 are fastened in blocks 4, which can be made of steel.
  • a plate 5 see figure 4,iis provided for dividing the force exerted by the block 4 over the end surface of the piece of timber 1.
  • the diameter of the hole 2 is made such large, that the hole can contain a sufficient amount of protective liquid which will penetrate into the wood of the entire pile.
  • a cap 6 for protecting the stretch rod 3 and the fastening block 4 for this.
