N&VO C\r\-2l£Kl HEREBY declare the invention, for which 1/we pray that a patent may be granted-to me/ns and the method by which it is to be performed, to be particularly described in and by the following statement: M A ^OVJMt^A-TlOK) SYSTEM j=~C>R, \NH-UCM NOTE. The claims must relate to a single inventiou, must be clear and succinct, and must be fairly based on the matter disclosed in the specification. They should form in brief a clear statement of that which constitutes the invention. Applicanu should be careful that their claims include neither more nor less than they desire to protect by their patent. Any unnecessary multiplicity of claims or prolixity of language should be avoided.

Claims should not be made for the efficiency or advantages of the invention. 27?- . the load bearing capability, sideways resistance and wind uplift resistance of a driven foundation post with the ground anchoring capability of diagonally driven angled posts, all joined and locked together as a structural unit by a collar, 5 thereby anchoring the building to a large volume of ground at each foundation location.

THIS INVENTION relates to Improvements to the shape and construction of the foundation collar and to the overall combination of the central load bearing post and the angled 10 diagonally placed anchor stakes, combined by a structural collar to form a ground anchoring foundation for suspended floor buildings located in areas which are subject to high velocity wind and/ or earthquakes which may change the cohesion of the bearing ground.

The most effective ground anchoring can be observed 1n tall trees which combine a tap root with a surrounding root system which anchor the tree to a large volume of ground and therefore resists overturning of the tree in storms. This invention is based on the same natural principle of load 20 dissipation combined with multiple ground pegging.

As a building will generally have at least nine or more of these foundations and the foundation posts will generally not extend far out of the ground, the overturning of tall 2 272?^n trees in severe storms observed when the ground surrounding the root system 1s weakened by water penetration causing liquefaction 1s not a problem. The liquefaction which can be caused to certain soil types by severe earthquake forces 5 will cause some displacement of this type of foundation system, but the system will resist building displacement sufficiently to prevent or reduce the loss of life. The foundation system components can be easily reclaimed and reused and the building repositioned on the reused 10 foundations.

The system is assembled from six basic components, the main component being the collar with its centrally located post guide and locking bolt, its diagonal webs locating angled stake guides and locking bolts and the bracing panels 15 between, the second component is the driven central load bearing post and the last four components are the driven angled stakes.

In order that the Invention may be more readily understood and put into practical effect, reference will now 20 be made to the accompanying drawings which illustrate a preferred embodiment of the invention and wherein: Fig. 1 is an isometric view of the completed foundation system as it would appear if the ground was transparent. 3 272P fin Fig. 2 shows the main component, the collar, top view 1s from one side and bottom view 1s from the top.

F1g. 3 1s a section showing the collar accurately located and levelled 1n position on the ground with the protruding 5 stake guides and webs anchoring 1t to the ground.

F1g. 4 is a section showing the first stake being driven through the stake guide 1n the collar.

F1g. 5 1s a section showing the second stake being driven through the stake guide 1n the collar. The locking bolt 1s 10 1n place on the first stake guide.

F1g. 6 1s a section showing the four stakes in place and the locking bolts in place on the stake guides. The central load bearing post 1s shown being driven through the guide in the post collar.

Fig. 7 is a section showing the completed foundation system with the locking bolt in place on the central collar.

Fig. 8 is a plan view of the completed foundation system.

Referring to the drawings and firstly to F1g. 1 where number 1 indicates the collar, 2 the central load bearing 20 post, 3 the'angled stakes, 4 the centre notches which are used to locate the collar 1n relation to building lines, 5 the post locating bolt, 6 the stake locating bolts.

Fig. 2 where number 7 indicates the post guide, 8 the 4 272? stake guides, 9 the guide webs, 10 the bracing panels, 11 the post locator bolt hole, 12 the threaded stake locator bolt holes.

F1gs. 3 and 4 where number 13 Indicates temporary 5 levelling wedges and 14 Indicates the ground.

F1gs. 5 and 6 where number 15 indicates stake locator bolts.

F1gs. 7 and 8 where number 16 indicates the volume of ground which the foundation system is anchored to. 10 It will be apparent from the above that the foundation system is very versatile and easy to install on location without the need for site drilling or the use of site concrete, as well as being retrievable and reusable if required, provides load bearing and uplift resistance as well 15 as resistance to sideways movement by being anchored to a substantial volume of ground.

The main component, the collar can be produced in a range of sizes and in either galvanised welded steel, galvanised cast steel or precast reinforced concrete. 20 The central post can be either pressure treated ground retention timber, galvanised steel or precast reinforced concrete.

The stakes can be either galvanised star shaped steel 27 2 P fence posts, rollformed galvanised steel fence posts or galvanised steel pipe, tubi or solid galvanised round steel section depending on ground hardness.

Location bolts can be galvanised steel.

For particularly corrosive soil conditions where organic compounds will shorten the life of concrete, galvanised steel can be used but with a coating of suitable plastic or asphalt to prolong life.

All such variations and modifications to the invention as 10 would be apparent to persons skilled 1n the art are deemed to fall within the broad scope and ambit of the invention as herein set forth. 6

Claims (3)

272 WHAT I CLAIM IS:

1. A method of anchoring a building with a suspended floor to the ground by a number of foundations combining the load bearing capability, uplift resistance and sideways resistance 5 of a driven post with the ground anchoring capability of diagonally placed driven angled stakes locked together by a collar which provide a central vertical guide for the post with four location slots 1n the top edge for the building line centralisation and holes for the locking bolt, four 10 diagonally located angled guides for the stakes with threaded holes for locking bolts, joined by diagonal vertical webs and horizontal bracing panels to form a resilient foundation system which when in place transfers all loads from the building to a large volume of ground and thereby resists 15 ground deterioration caused by wind and earthquake forces on the building.

2. A method of anchoring a building as outlined in claim 1 on either a level or a sloping site.

3. A method of anchoring a building substantially as 20 hereinbefore described with reference to accompanying drawings. PEDER ULRIK HANSEN as inventor 7
