FIELD: construction.
SUBSTANCE: in a device of structure reinforcement with the help of composite material tapes, comprising a composite material tape, ends of which are connected to anchor assemblies comprising support plates fixed on a reinforced concrete beam, add-on plates to clamp ends of the tape, at the same time one of anchor assemblies is made as capable of connection to a system of lengthy tape tensioning in longitudinal direction, the composite material tape is equipped with ends installed on it and connected to brackets installed on support plates of anchor assemblies, and connection of ends with brackets is made in the form of hinged joints, which allow for rotation of tape ends relative to the beam in case of its deformations. Besides, one of tape ends is made with an eye that carries a cardan connected by other end to the eye of the bracket in one anchor assembly, and the other end is made with a threaded hole for a threaded rod, passing with a gap via a hole of the bracket of the other anchor assembly, at the same time the threaded rod by one end is screwed into the threaded hole of the end, and on the other end it carries washers, a nut and lock-nut for its fixation relative to the bracket. Besides, ends are made with flat sites and are equipped with add-on plates for fixation on the tape by means of bolts, at the same time on clamping surfaces of add-on plates and flat sites there are accordingly grooves made, which stretch in direction perpendicular to the longitudinal line of the lengthy tape and arranged in parallel to each other and preferably with the same pitch between them.
EFFECT: development of a device for reinforcement of a building structure by reinforcement from polymer composite material on the basis of high-strength artificial fibres, providing for reduced costs for installation and operation, having increased reliability in operation, increased service life.
