Abstract
The jacking plate may be used to reinforce structural assembly elements that may be required to withstand the force of the use of a jack bolt to separate assembly elements. The jacking plate may be attached intermediate one structural element and a nut plate. A bushing may be attached in a second structural element through which bushing the jack bolt is threaded to apply force against the jacking plate. The jacking plate may be constructed of a hardened metal such as stainless steel to inhibit deforming of the structural element and nut plate.
Claims9
A device to reinforce a structural assembly the elements of which may be separated using a jack bolt, comprising:
- a jacking plate having a bolt aperture formed therein and a plurality of fastening apertures formed therein;
- and
- said jacking plate attachable intermediate a structural element and a nut plate.
A device to reinforce a structural assembly the elements of which may be separated using a jack bolt, comprising:
- a jacking plate having a bolt aperture formed therein that is sized for a fastening bolt to pass therethrough and for a jack bolt to be inhibited from passing therethrough;
- said jacking plate having a plurality of fastening apertures formed therein;
- and
- said jacking plate attachable intermediate a structural element and a nut plate.
A jack bolt apparatus for separating structural assembly elements, comprising:
- a jacking plate having a bolt aperture formed therein that is sized for a fastening bolt to pass therethrough and for a jack bolt to be inhibited from passing therethrough;
- said jacking plate attached intermediate an inner structural element and a nut plate;
- a bushing attached to an outer structural element for threadable engagement with a jack bolt.
A method for separating structural assembly elements that may be fastened by a fastening bolt and a nut plate, comprising the steps of:
- attaching a jacking plate having a bolt aperture formed therein that is sized for a fastening bolt to pass therethrough and for a jack bolt to be inhibited from passing therethrough intermediate a first structural element and a nut plate;
- attaching a bushing to a second structural element for threadable engagement of said jack bolt;
- threadably engaging said jack bolt into said bushing;
- and
- rotating said jack bolt to engage said jacking plate to apply a separation force between said first structural element and said second structural element.
