Large-tonnage carbon fiber superimposed plate bundle anchorage

Abstract

The invention discloses a large-tonnage carbon fiber superimposed plate bundle anchorage including an anchorage tube and a carbon fiber fixing plate bundle; the anchorage tube is provided with a filling through hole; the tail end of the filling through hole is provided with a sealing cover plate, and the front end of the filling through hole is provided with an end sealing piece; the carbon fiber fixing plate bundle passes through the end sealing piece and then enters the filling through hole. The anchorage is characterized in that the sealing cover plate is provided with a wedge block; the wedge block extends inward into the filling through hole; the carbon fiber fixing plate bundle is divided into a first plate bundle and a second plate bundle which are symmetrical; two sides of the wedge block is symmetrically provided with two wedge block slopes which gradually approach to each other when the two wedge block slopes extend inward from the tail end of the filling through hole; the first plate bundle and the second plate bundle are arranged on the wedge block slopes at two sides of the wedge block in a reclining manner; the tail end of the first plate bundle and the tail end of the second plate bundle are respectively fixedly connected with the sealing cover plate; and a gap in the filling through hole is filled with an epoxy resin mixed medium. The anchorage has the advantages that the anchorage can effectively anchor the carbon fiber fixed plate bundle having large bearing capacity.

Description

technical field [0001] The invention relates to a plate bundle anchor, in particular to a large-tonnage carbon fiber laminated plate bundle anchor. Background technique [0002] Carbon Fiber Reinforced Polymer / Plastic (CFRP) has outstanding advantages such as light weight, high strength, high modulus, and corrosion resistance. It has been widely used in aerospace, automobile, civil engineering and other fields. Existing anchors can only anchor a small amount of carbon fiber plates composed of carbon fiber reinforced composite materials, and the bearing capacity of the carbon fiber plate bundle formed after anchoring a small amount of carbon fiber plates is between 30 and 150 tons. When the carbon fiber plate bundle is composed of carbon fiber plates, since the compressive stress on the carbon fiber plate bundle at the anchorage area is basically consistent from the loaded end to the free end, the compressive stress on each part of the carbon fiber plate bundle cannot be adju...

[0002] Carbon Fiber Reinforced Polymer / Plastic (CFRP) has outstanding advantages such as light weight, high strength, high modulus, and corrosion resistance. It has been widely used in aerospace, automobile, civil engineering and other fields. Existing anchors can only anchor a small amount of carbon fiber plates composed of carbon fiber reinforced composite materials, and the bearing capacity of the carbon fiber plate bundle formed after anchoring a small amount of carbon fiber plates is between 30 and 150 tons. When the carbon fiber plate bundle is composed of carbon fiber plates, since the compressive stress on the carbon fiber plate bundle at the anchorage area is basically consistent from the loaded end to the free end, the compressive stress on each part of the carbon fiber plate bundle cannot be adjusted separately, so The carbon fiber bundles are always subject to a large compressive stress at the loaded end, which can easily lead to damage to the carbon fiber bundles in this area, causing the carbon fiber bundles to be damaged in advance before their ultimate tensile strength is fully realized. Therefore, the existing Anchors cannot effectively anchor carbon fiber bundles with greater load-bearing capacity
