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 a variable-clamping-force corrugated clamping plate anchor for an FRP sheet, and relates to an anchor for an engineering structure in the field of high-strength composite materials. The variable-clamping-force corrugated clamping plate anchor for the FRP sheet includes an upper corrugated clamping plate, a lower corrugated clamping plate, bolts, nuts, washers and the FRP sheet. The FRP sheet passes through the upper corrugated clamping and the lower corrugated clamping plate, the upper corrugated clamping plate and the lower corrugated clamping plate clamp the FRP sheettightly, the washers are arranged at bolt holes of the upper corrugated clamping plate and the lower corrugated clamping plate, the nuts penetrate through the upper corrugated clamping plate and thelower corrugated clamping plate, and the FRP sheet is anchored by tightening the nuts. The anchor adopts the corrugated clamping plates to replace flat clamping plates to clamp the FRP sheet, and theanchoring bolt radius gradually increases from an outlet to the end part of the anchor, the clamping force provided by the anchoring bolts further gradually increases from the outlet to the end part of the anchor, the stress peak at the outlet of the anchor can be effectively reduced, the anchoring efficiency is improved, the anchoring length is shortened, materials are saved, and economy is improved.

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...
