TH4478B - Configuration of end fixing using anchors of tensile steel components Where there is independent oscillation of structural components subject to aerodynamic stress. - Google Patents

Abstract

Fixing the ends of tensile steel wires This can be done using an anchor. The rebar is threaded through parallel tubes in the anchor body and ends fixed to the anchor body by wedge-shaped clamps. These pipes are fixed in size and slightly larger in diameter than the steel rod. An elastic ring is inserted in the end of the anchor to transfer the deflection force of the steel wire. A retaining ring is used to collect several steel strands together into a single strand. A support is inserted between the retaining ring and the steel rod body to transfer the deflection force of the steel wire in this area. The support is made of softer material. Retaining ring and steel wire The material from which the elastic retaining ring is made is weaker than the anchor itself. and the steel line This arrangement of fixing the ends of the tensile steel wires eliminates the force from the deflection of the steel wires occurring in two areas.
