Carbon beaverboard anchorage

Abstract

The invention relates to an anchorage device, in particular to a carbon fiber plate anchorage device used in civil engineering and building construction. The anchorage device consists of an anchor plate and a clamping piece; the anchor plate is a whole part and is internally provided with a wedged-shape through hole, the clamping piece is a two-piece type wedge block, the clamping piece is wedged into the anchor plate for tightly clamping the carbon fiber plate, then the wedge block is in close fit with the wedged-shape through hole in the anchor plate; the anchor plate is of a cylinder with rectangular or square or elliptic or circular cross section, the anchor plate is internally provided with the wedged-shape through hole with the rectangular or square or elliptic or circular cross section and tapering longitudinal section, and the folding contour formed after the clamping piece is wedged into the anchor plate for tightly clamping the carbon fiber plate is the same as that of the wedged-shape through hole with the rectangular or square or elliptic or circular cross section and tapering longitudinal section in the anchor plate; the clamping face of the clamping piece has a layer of a contact reinforcing material of the carbon fiber plate; and the contact surface of the clamping piece and the anchor plate is coated with lubricating oil or lubricating grease. The anchorage device has the advantages of reliable anchoring property, simple and compact structure, convenient manufacture, construction and operation, high efficiency and various shapes, and the anchorage device can meet the requirement of different construction environments.

Description

Technical field: [0001] The invention relates to an anchor, in particular to a carbon fiber plate anchor used in civil engineering. Background technique: [0002] Carbon fiber plate is a new type of high-strength material, which is usually attached to the surface of concrete components in civil engineering to strengthen the strength of components. If it is pre-tensioned before pasting and then anchored to the surface of the component, the bending strength and crack resistance of the component can be enhanced, and its strength can be fully utilized. Therefore, prestressed carbon fiber reinforced concrete members have obvious advantages over ordinary pasted fiber reinforcement. However, the prestressing reinforcement technology requires tensioning and anchoring of carbon fiber sheets. Although carbon fiber sheets have high tensile strength but low transverse shear strength, it is easy to cut off carbon filaments when clamping and anchoring them, and they will slip if they are...
