ABSTRACT:
A tensioning device for prestressing the rod members and transverse members connected thereto and operatively associated therewith has a jack assembly connected between at least two rod members and disposed to engage the transverse member, the jack assembly includes an expansion member such as a piston which can exert tensile forces incrementally on the rod members and the transverse member to evenly stress the same to a predetermined level. The tensioning device may have a pressure plate between the jack assembly and the transverse member to exert a more uniform pressure along the entire transverse member.
