Abstract:
1. A system for reinforcing an existing vertical monopole tower having an annular tower wall in horizontal cross-section and adapted to increase the capacity of the tower for supporting communication antennas, said annular tower having generally vertically extending flat outer surfaces around the periphery of said tower, said system comprising a plurality of elongated rigid reinforcing channels extending substantially vertically on peripherally spaced said outer surfaces of said tower wall, each of said channels having parallel spaced flange portions integrally connected by a web portion and defining a longitudinally extending and outwardly facing opening, each of said flange portions of each said channel having a uniform wall thickness substantially greater than a uniform wall thickness of said web portion, said web portion and said flange portions of each said channel having a flat base surface mounted directly on and contacting one of said flat outer surfaces of said tower wall, said web portion of each said channel having longitudinally spaced circular holes, said tower wall having vertically spaced circular holes aligned with and having the same diameter as said holes within said web portion of said each said channel, and blind tensile shear connectors extending through and tightly filling the aligned said holes without clearance and positively securing said reinforcing channels to said flat outer surfaces of said tower wall.
