Claims
- 1. An anchor member for constructing an anchoring device having a plurality of tendons extending from an opening therein that is accessible from only one side thereof, in a structure, wherein said member comprises:
a wall member, bounding a cavity of a substantially oblong, tapering shape with two ends, the first end comprising the opening, a cross-sectional area of the first end being smaller than a cross-sectional area of another portion of the anchor member; and a bottom wall at the second end.
- 2. The anchor member of claim 1, having a substantially frustoconical shape.
- 3. The anchor member of claim 1, having a substantially frustopyramidal shape.
- 4. The anchor member of claim 1, wherein the wall member has an inlet disposed proximate to the bottom wall, said inlet communicable to a tube for injecting a liquid or semi-liquid product.
- 5. The anchor member of claim 4, wherein the wall member has an outlet disposed proximate to the opening, said outlet communicable to an exhaust tube.
- 6. The anchor member of claim 1, wherein the opening is provided with means for fastening a guide tube for containing tendons.
- 7. The anchor member of claim 1, wherein the wall member is provided on an outer lateral surface with at least one peripheral widening.
- 8. The anchor member of claim 1, wherein the wall member is made at least partially of metal.
- 9. The anchor member of claim 1, wherein the wall member is made at least partially of synthetic material.
- 10. The anchor member of claim 1, wherein the wall member is made at least partially of concrete.
- 11. The anchor member of claim 1, associated with a number N of tendons of claim 12 for constructing an anchoring device accessible from a single side, wherein the cross-sectional area of the cavity opening is larger than the sum of the cross-sectional areas of the number (N−1) of said tendons added to a maximum cross-sectional area of the end portion of one of said tendons.
- 12. A tendon for insertion in an anchor cavity of an anchoring device with an opening accessible from only one side, said tendon comprising:
a traction rod having a first end and an intermediate portion with a first cross-sectional area and a second end having an end portion with a second cross-sectional area larger than said first cross-sectional area.
- 13. The tendon according to claim 12, wherein the end portion comprises an end piece fixed to the second end of the traction rod.
- 14. The tendon according to claim 12, wherein the end portion is obtained by deforming the second end of the traction rod (40).
- 15. The tendon according to claim 14, wherein the traction rod comprises a cabled assembly of undivided strands, the end portion formed by displacement of at least one of said undivided strands, a supplementary part provided for holding said at least one strand in displaced position.
- 16. The tendon of claim 12, wherein the end portion has a convex lower end thereof.
- 17. The tendon of claim 12, wherein the end portion has a convex upper end thereof.
- 18. The tendon of claim 12, wherein the end portion has a tapering central portion, such that a smallest cross-sectional area thereof is adjacent to an upper end portion thereof and a largest cross-sectional area thereof is adjacent to a lower end portion.
- 19. The tendon of claim 12, wherein the end portion has a right cylindrical central portion with constant cross-sectional area, bounded by an upper end portion and a lower end portion.
- 20. The tendon of claim 12, made at least partially of metal.
- 21. The tendon of claim 12, made at least partially of synthetic material.
- 22. An anchoring device in a structure, the device having an opening accessible from a single side of the structure, comprising:
anchoring member secured in the structure, the anchor member comprising a well member, bounding a cavity of a substantially oblong, tapering shape with two ends, the first end comprising the opening, a cross-sectional area of the first end being smaller than a cross-sectional area of another portion of the anchor member, and a bottom wall at the second end; and a plurality of tendons, each said tendon comprising a traction rod having a first end and an intermediate portion with a first cross-sectional area and a second having an end portion with a second cross-sectional area larger than said first cross-sectional area, N such tendons inserted into the anchor member with the second ends in the cavity and the first ends and intermediate portions extending outwardly therefrom, wherein the first and second cross-sectional areas of the traction rods and the cross-sectional area of the opening are related such that when N traction rods are in place, the N traction rods cannot be arranged at the opening to allow the second cross-sectional area of one additional traction rod to pass through the opening.
- 23. The anchoring device of claim 22, wherein the cavity has at least one cross-sectional area that is greater than the sum of the maximum cross-sectional areas of the N second ends.
- 24. The anchoring device of claim 22, wherein the cross-sectional area of the opening of the cavity is less than the sum of the cross-sectional areas of the second ends of the N tendons inserted in said cavity.
