Tension monitoring apparatus

摘要

A tension monitoring assembly or device permanently installed between a connection or anchor point and a guy cable line or structural rod allows constant monitoring and increase confidence that the guy cable or structural tension rod remains tensioned to the proper value. The device includes a plurality of compression members and a connecting member that are arranged between connection points such that the tension between a first connecting point and a second connection point may be set to a selected value. The tension on the device is determined by the distance between two members of the device such that a change in the tension from a set amount will result in a change of the distance between the two members. This change in distance can be determined by indicia that are visible as the two members move with respect to each other.

主权项

1. A device for monitoring the tension between a first and a second connecting point, the device comprising:
a first member having a first end to be attached to the first connecting point and a cylindrical projection having a selected diameter extending away from the first end to a second end, the cylindrical projection and the second end of the first member, respectively, defining walls and a base of a cavity, said cavity opening toward the first end and said cavity having a diameter less than said selected diameter and said base of said cavity defining an aperture there-through having a diameter less than said cavity diameter; a second member having a first end to be attached to the second connecting point, the second member further defining a cylindrical aperture having a base and a diameter greater than the selected diameter, the cylindrical aperture extending from the base of the aperture to a second end of the second member such that the cylindrical projection of the first member is received by the cylindrical aperture with a sliding fit; a compression member received by the cavity defined in the first member; and a connecting member extending between the base of the cylindrical aperture of the second member, through said aperture in said base of said cavity of said first member and through said compression member securing the first member to the second member, the compression member and the connecting member arranged between the first member and the second member such that tension between the first connecting point and the second connecting point may be set to a selected value by compressing the compression member a selected amount and thereby changing a distance and resulting tension between the first end of the first member and the first end of the second member, and such that an unintended change in the tension from the selected value will result in an observable change of the distance between the first end of the first member and the first end of the second member.
