Abstract

The invention discloses a tensioning anchoring device and tensioning anchoring method suitable for a FRP grid with applied pre-stress; the tensioning anchoring device comprises a lower liner plate, an upper platen, and a connector fastening the upper platen with the lower liner plate; the top surface of the lower liner plate is provided with grooves used for nesting the FRP grid and having equal intervals with the FRP grid vertical and horizontal fiber wood; the bottom surface of the upper platen is provided with convex ribs clamped into the grooves, wherein the convex ribs comprises transverse ribs and vertical ribs; the bottom of the groove and one side face, bearing the grid shearing force, of the groove are provided with a first cushion layer; the convex surface of the convex ribs are provided with a second cushion layer. The FRP grid can be applied with pre-stress so as to reinforce a structure, thus fully expressing fiber reinforced composite material intensity, and improving reinforcing effect.

Description

Technical field: [0001] The invention is a grid tension anchoring device, which is applicable to the technical fields of civil engineering and traffic structure reinforcement, and is especially suitable for applying prestress to old buildings by using grid-shaped fiber-reinforced composite materials to enhance the structural bearing capacity. Background technique: [0002] At present, many buildings are under harsh environments such as severe cold, ocean, industry, and alpine climate. The building structure is gradually aging, and the bearing capacity of local components is reduced, which brings great safety hazards to the structure. [0003] Fiber-reinforced composite (FRP) is a material formed by winding, molding or pultrusion of fibers and matrix materials. It has the characteristics of high tensile strength, light weight, corrosion resistance and fatigue resistance. These characteristics make FRP material can be used as a good structural reinforcement material. [0004]...
