Abstract
The invention relates to a prestressing element for prestressing a measuring sensor arranged between structures or in a recess of a structure. The application and release of the prestress can only be carried out at one point by means of a key. The invention also relates to an arrangement of a plurality of prestressing elements which can be individually prestressed and released with the same tool.

A prestressing element for application and release of prestress to a sensor, comprising:
- a base having at least one wedge surface;
- a clamping element having an inclined surface in mating engagement with said wedge surface of said base;
- and
- a screw disposed through said clamping element, said screw having an axial direction, wherein rotation of said screw in a first direction urges said inclined surface of said clamping element against said wedge surface of said base such that said base is urged in a direction transverse to said axial direction of said screw;
- wherein said base is configured such that urging of said base in said transverse direction causes prestress on a sensor, and wherein rotation of said screw in an opposite direction from said first direction causes release of the prestress on the sensor.
A prestressing element for application and release of prestress to a sensor, comprising:
- a screw having an axial direction and having threading disposed thereon;
- a driven member in threaded engagement with said screw, wherein rotation of said screw in a first direction causes said driven member to be urged in a direction transverse to said axial direction of said screw so as to apply prestress to a sensor;
- wherein rotation of said screw in an opposite direction from said first direction causes said driven member to be urged the direction transverse to said axial direction of said screw so as to release prestress to the sensor, and wherein application of prestress and release of prestress is effected through rotation of said screw in opposite directions.
A plurality of prestressing elements for application and release of prestress to sensors, at least two of said prestressing elements each comprising:
- a base having at least one wedge surface;
- a clamping element having an inclined surface in mating engagement with said wedge surface of said base;
- and
- a screw disposed through said clamping element, said screw having an axis with an axial direction, wherein rotation of said screw in a first direction urges said inclined surface of said clamping element against said wedge surface of said base such that said base is urged in a direction transverse to said axial direction of said screw;
- wherein said base is configured such that urging of said base in said transverse direction causes prestress on a sensor, and wherein rotation of said screw in an opposite direction from said first direction causes release of the prestress on the sensor;
- wherein said axes of said screws are aligned with one another.
