Abstract
In order to make a tension member (1) substantially removable from the ground or from a structure, a central element (2) thereof is completely severed. If the tension member is to be further weakened, at least one outer element (3) is also severed besides the central element. A supporting contrivance (5) is applied to the tension member either around the point of separation (4) of the central element or around both points of separation (4, 6) of the central element and of the outer element. By application of a load, the tension member is torn apart near the point or points of separation so that the major part of the tension member can be pulled out of the ground or structure and, if need be, reused.
Claims16
A tension member to be anchored in the ground or in a structure, comprising:
- a central element,
- a plurality of further elements surrounding the central element, at least the central element being completely severed in a predetermined zone thereof, to form a point of separation, and
- a supporting means applied around the tension member at said predetermined zone, wherein the distance to the point of separation of said central element from the end of said predetermined zone measured in the direction of an applied load is fixed according to the magnitude of the load to be exerted on said predetermined zone for removal of said tension member from an anchored position.
A tension member to be anchored in the ground or in a structure and which is intended to be removed from the ground or structure after use, comprising:
- a central element being completely severed at a predetermined point of separation,
- a plurality of outer elements surrounding said central element around said point of separation,
- a supporting means applied around the tension member at a predetermined zone relative to said point of separation wherein the distance between said point of separation of said central element and the end of said predetermined zone measured in the direction of an applied load is fixed according to the magnitude of the load to be exerted for removing said tension member in a range between a required working load of said tension member and the breaking load of a tension member without said point of separation.
A tension member to be anchored in the ground or in a structure and subsequently removed therefrom for further use, comprising:
- a central element and a plurality of outer elements surrounding said central element, at least said central element being completely severed to form a point of separation, and
- a supporting means applied around said central element and said plurality of outer elements at a predetermined zone relative to said point of separation, wherein a first distance from said point of separation of said central element to a first end of said predetermined zone measured in the direction of an applied load is fixed relative to a second distance to the point of separation of said central element from a second end of said predetermined zone measured in the direction of said applied load wherein the magnitude of said applied load necessary to remove said tension member is determined as a function of the ratio of said first and second distances.
