Embodiment Construction

[0033] Below in conjunction with accompanying drawing and example describe in detail:

[0034] 1. FRP sheet anchorage

[0035] 1. Overall

[0036] Such as figure 1 , the present invention includes a sheet 10, an upper anchor plate 20, a lower anchor plate 30 and a bolt 40;

[0037] The sheet 10 is placed between the upper anchor plate 20 and the lower anchor plate 30, the upper anchor plate 20 and the lower anchor plate 30 clamp the sheet 10 together, and the bolt 40 passes through the plate holes of the upper anchor plate 20 and the lower anchor plate 30 25 anchors the upper anchor plate 20 and the lower anchor plate 30 tightly.

[0038] When necessary, corrugated pipes 50 are connected at both ends of the anchorage, and the sheet 10 passes through the corrugated pipes 50 .

[0039] 2. Functional components

[0040] 1) Sheet 10

[0041] Such as Figure 2.1 , Figure 2.2 , the sheet 10 is either an FRP sheet or an FRP cloth, which is a thin-walled strip structu...

Abstract

The invention discloses an FRP (Fiber Reinforced Polymer, fiber reinforced polymer) sheet anchor and its anchoring method, and relates to an anchor for engineering structures in the field of high-performance polymer structural materials. The present invention comprises a sheet (10), an upper anchor plate (20), a lower anchor plate (30) and a bolt (40); the sheet (10) passes through a bellows (50) and is placed on the upper anchor plate (20) and the lower Between the anchor plates (30), the upper anchor plate (20) and the lower anchor plate (30) clamp the sheet (10) together, and the bolts (40) pass through the upper anchor plate (20) and the lower anchor plate (30) The upper anchor plate (20) and the lower anchor plate (30) are anchored tightly by the plate holes (25). The anchorage is non-corroding, and it is placed in a completely non-metallic engineering structure together with the FRP sheet, which has durability; it is light in weight and is used in bridges and other structures to enhance the spanning ability; it has good electromagnetic insulation.

Description

technical field [0001] The invention relates to an anchor for engineering structures in the field of high-performance polymer structural materials, in particular to an FRP (Fiber Reinforced Polymer, fiber reinforced polymer) sheet anchor and its anchoring method. Background technique [0002] The Achilles heel of steel as a structural material is as follows: First, corrosion changes the chemical composition of the structural material, resulting in the reduction or even loss of the original mechanical properties of the steel, so the corrosion problem seriously affects the durability of the structure; secondly, with the development of economy and science, People's demand for building materials is higher and higher, and steel beams and bars (steel wires) are difficult to meet the requirements; third, steel is a consumable resource and is not renewable. From the perspective of human long-term development, use FRP instead of steel as building materials is an inevitable trend. ...
