DEVICE FOR INTRODUCING A FORCE INTO TENSION ELEMENTS MADE OF FIBER-REINFORCED PLASTIC FLAT STRIP PLATES Russian patent published in 2017 - IPC E01D22/00 E04C5/12 

FIELD: construction.

SUBSTANCE: invention relates to a device (1) for creating pre-stress in the clamping elements (2), made from fiber-reinforced plastic flat strip plates with clamping element (3), which is located on the tension element (2) and has at least one contact surface interacting with a tension element (2), as well as at least one rigid sleeve (4), that is located, at least around one clamping element (3) and the tension element (2) and thus, by means of clamping element (3) applies a compressive pressure to tension element (2).Clamping element (3) is made of plastic, which has a module of elasticity in the range of 1,000–5,000 MPa, tensile strength in bending ≥ 25 MPa and ultimate compression strength ≥ 25 MPa.

EFFECT: creation of pre-stress in clamping elements.
