Abstract
Abstract For an anchorage in the ground, an anchoring head is provided which can be driven into the ground in an orientation providing a small frontal area and small resistance to the driving-in force. Attached to the head at a point laterally offset therefrom is a rod or cable through which the anchoring force is to be transmitted. When the head has been driven in to the anchorage depth, tension is applied to the rod or cable which, by virtue of said offset, tilts the head into a different orientation in which it presents much greater resistance to pull-out forces.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
118 words
Anchorage apparatus comprising: an anchorage head adapted to be forced into the ground in a first orientation affording low penetration resistance, said head affording pull-out resistance greater than said penetration resistance when in a second orientation tilted with respect to said first orientation; articulation means laterally offset from said head; pulling means connected to said articulation means for tilting said head from said first orientation into said second orientation; said head comprising an anchor plate which is flat, rectangularly shaped and provided with a transverse member comprising a transverse plate fixed at one end to one side of said anchor plate perpendicularly to said anchor plate, said articulation means being at the other end of said transverse plate.
Claim 2
Dependent Claim
118 words
Anchorage apparatus comprising: an anchorage head adapted to be forced into the ground in a first orientation affording low penetration resistance, said head affording pull-out resistance greater than said penetration resistance when in a second orientation tilted with respect to said first orientation; articulation means laterally offset from said head; pulling means connected to said articulation means for tilting said head from said first orientation into said second orientation; said head comprising an anchor plate which is flat, rectangularly shaped and provided with a transverse member comprising a transverse plate fixed at one end to one side of said anchor plate perpendicularly to said anchor plate, said articulation means being at the other end of said transverse plate.
Claim 3
Dependent Claim
20 words
Anchorage apparatus according to claim 1 wherein said transverse member includes another plate which is parallel to said transverse plate.
Claim 4
Dependent Claim
25 words
Anchorage apparatus according to claim 1 wherein said anchorage head includes a second rectangular plate connected to said transverse member parallel to the anchor plate.
Claim 5
Dependent Claim
18 words
Anchorage apparatus according to claim 1 wherein said articulation means includes a pivot parallel to said anchor plate.
Claim 6
Dependent Claim
13 words
Anchorage apparatus according to claim 1 wherein said pulling member is a chain.
Claim 7
Dependent Claim
13 words
Anchorage apparatus according to claim 1 wherein said pulling member is a rod.
