<p>This disclosure teaches a movable sleeve connector for use in a method for replacing an existing utility pole (usually wood), without disturbing hardware mounted thereon. As taught in United States patent 3,911,548, the utility pole includes a proximal section having a bottom end attached to the earth and a distal section having hardware mounted thereon. The distal section (with its hardware intact thereon) is severed from the proximal section. A new pole section (preferably of prestressed concrete) is attached to the earth appropriately located and adapted for receiving the distal section in axial abutting seating thereon whereby a joint is defined therebetween. The distal section then is moved to sit coaxially on the new pole section and is engaged to the new pole section by means of a movable sleeve which is annular and engageable about outsides respectively of the new pole section and the distal section. The sleeve is movable between an inoperative position (wherein it is displaced from the joint and an operative position (wherein it spans the joint). The sleeve may be attached to both the distal section and to the new pole section by known means such as screws, bolts, grout or the like. The joint is sealed by means of a suitable sealant, such as the grout.</p> |
