Embodiment Construction

[0024] Below in conjunction with accompanying drawing and example the present invention is described in further detail:

[0025] Step 1: Pass the FRP sheet 1 through the upper corrugated splint 2 and the lower corrugated splint 3 .

[0026] Step 2: The upper corrugated splint 2 and the lower corrugated splint 3 tightly clamp the FRP sheet 1, the upper and lower corrugated splints are aligned, and epoxy resin is added between the upper corrugated splint 2, the lower corrugated splint 3 and the FRP sheet 1 Agent 7.

[0027] Step 3: Add washers 6 at the bolt holes of the upper wave splint 2 and the lower wave splint 3, and the bolt 4 passes through the upper wave splint 2 and the lower wave splint 3.

[0028] Step 4: Tighten the nut 5 to anchor the FRP sheet 1 tightly.

Abstract

The invention discloses an FRP sheet variable clamping force waveform splint anchor, which relates to an engineering structure anchor in the field of high-strength composite materials. Including upper corrugated splint, lower corrugated splint, bolts, nuts, washers and FRP sheet. The FRP sheet passes through the upper and lower corrugated splints, and the upper and lower corrugated splints tightly clamp the FRP sheet. Add washers to the bolt holes of the upper and lower corrugated splints. The anchorage adopts a wave splint instead of a flat splint to clamp the FRP sheet, and the radius of the anchor bolt increases gradually from the outlet to the end of the anchor, and the clamping force provided by the anchor bolt also increases from the outlet to the end. Gradually increasing can effectively reduce the stress peak value at the outlet of the anchorage, improve anchorage efficiency, shorten anchorage length, save materials and improve economy.

Description

technical field [0001] The invention relates to an anchor for engineering structures in the field of high-strength composite materials, in particular to an FRP sheet variable clamping force wave splint anchor. Background technique [0002] FRP (Fiber Reinforced Polymer, fiber reinforced plastic) has the advantages of light weight, high strength, corrosion resistance, and good fatigue resistance. Compared with steel FRP, it has better development prospects. FRP was originally only used for the reinforcement of engineering structures, but now it can be widely used in various engineering structures and has achieved good results. The application of FRP in new bridge projects is generally used for cables, prestressed tendons, and external prestressed components on bridges, which can reduce costs, facilitate construction, and increase the service life of components. Nowadays, the market demand for FRP is increasing, and the technical level is also steadily improving. [0003] FR...
