This article presents an analysis of existing devices for tensioning composite polymer reinforcement. It is shown that application of anchoring devices is gaining wider popularity due to the simplicity of design and technology of rebar fixation. The carrying capacity of such devices is significantly affected by the material of the anchor wedges, the strength of the anchoring (pre-pressing) of the wedges, and the technology of rebar manufacturing. The conducted research includes experimental study of the load capacity of an anchor-type device for tensioning glass-composite reinforcement of three different profiles in the stress state in the range from 40 to 70 percent of tensile strength. The method of testing, criteria for carrying capacity evaluation, as well as established influence patterns of the anchor wedges prepressing on the rebar slippage were described. It was found that each diameter of the reinforcement and type of profile requires its own dependencies to assign fixing forces that provide the required tension of the reinforcement in prestressed concrete products. The recommended technical characteristics were established for the developed anchoring device. They include preliminary fixing parameters for the ends of three different types of reinforcement profiles with a diameter of 8 mm, while maintaining the required strength of the reinforcing bar and preventing slipping in the device under the action of tensile loads, specified according to SP 295.1325800.201.
