Definitions

  • This invention relates to a supporting member, typically a post, for use in supporting a structure, apparatus or article, typically a fence.
  • support members such as posts used to support structures such as fences, buildings or other suitable structures.
  • Ground engaging posts have to be of sufficient size, strength and durability for the purpose intended.
  • Ground engaging posts commonly used are typically made of wood and as such have to be chemically treated with chemicals such as Copper Chrome Arsenate (CCA).
  • CCA Copper Chrome Arsenate
  • the chemicals within the wooden post leak into the soil and subsequently into the water table from which draw drinking water is drawn from. Therefore, any areas where high concentration of posts are used in a relatively small area, such as wine growing region, the leaking of dangerous chemicals such as CAA, into the water aquifer can have severe consequences as the levels of these chemicals build up over time resulting in the gradually poisoning of livestock and/or humans who drink water drawn from the contaminated water aquifer.
  • treated grape posts When treated grape posts are broken at the time of grape harvest, it is replaced with a new treated post. This post is fully treated and loaded up with CCA treatment. When placed in the ground it repeats the cycle of discharge and leaching of the CCA treatment back into the ground. This leads to a level of poisoning the water aquifer and ground crops such as grapes, kiwi fruit, apples, etc as well as crops which may be planted after the posts are removed such as wheat, barley, corn, etc.

For instance when used to support grape vines, where strainer posts take the major side loading, the post of the invention with only two elongate members may be oriented to take the lateral loads.
  • a post with four elongate members provides a shape more closely approximating a square wooden post and can thus use hardware typically used with wooden posts.
  • the post In use as a fence post, the post is erected in the usual manner eg by digging methods or impact/vibrating methods.

  • a lightweight and rigid material is a plastics material.
  • the post could also be made from other lightweight and rigid materials such as fibreglass or metal, typically aluminium.
  • the post for driving may be filled with a material which may later dissolve, for instance where the pole is used in an agricultural setting it may contain cast superphosphate fertiliser, which will gradually leach out.
  • the post is preferably made from an extrusion process, and if fibreglass is included may be made by pultrusion. Other manufacture processes are envisaged such as injection moulding or rotary moulding.
  • the post can be coloured and this can be achieved by applying a coloured film during manufacture thereof.
  • the main colour of the manufacture of the post would be black medium density polyethylene, but other coloured density polyethylene could be similar used.
  • the post could have a thin colour film applied to the outside of the pipe during the moulding process. This is purely to enhance its looks and aesthetics.
  • the post as disclosed herein has the advantages of being lightweight, rigid, inexpensive, less labour intensive to use, able to be reinforced with high impact substances, easy to remove, safe to the environment and water table.
