METHOD FOR PREVENTION OF DESTRUCTION OF BENT REINFORCED CONCRETE GIRDERS OF SUPERSTRUCTURE OF BRIDGES FROM DETACHMENT OF REINFORCING ELEMENTS BY WOVEN LINENS ON NEAR-SUPPORT SECTIONS Russian patent published in 2019 - IPC E01D22/00 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used in erection and reconstruction of residential and industrial structures. In method of prevention of destruction of bent reinforced concrete girders of superstructure of bridges from detachment of reinforcing elements by woven linens on bearing sections carbon tape is glued to horizontal surface of reinforced concrete beams from below, fixed at one end and gradually smoothed and fixed along the entire length, wherein in the longitudinal direction of the structure at its outer corners the chamfers are arranged with leg of 1–2 cm and the yokes are fixed from the carbon band on the prestressed beam, and high-strength carbon tape is extended beyond the supports and turned over the ends of the beam by not more than 15 cm and clamping bars are installed on the ends of beams using dowels, which keep the tape from sliding on concrete under action of loads.

EFFECT: invention allows to prevent destruction of bent reinforced concrete beams of superstructure of bridges from detachment of reinforcing elements by woven linens on near-support sections due to retention of tape from sliding on concrete under action of load, to increase service life of reinforced concrete beams.
