Problems solved by technology

However, due to the large modulus, high brittleness, and low transverse shear strength and transverse compressive strength of the carbon fiber plate, simple clamping and anchoring will lead to brittle fracture of the carbon fiber plate; in addition, the carbon fiber plate has a certain width, and it is difficult to achieve Creates a uniformly distributed tensile stress on the carbon fiber sheet

Embodiment 1

[0017] Such as Figure 1-6 As shown, an anchoring connection device for carbon fiber reinforced resin-based composite material plates includes two aluminum plates 2, carbon fiber plates 3 and steel connectors, and the steel connectors include an upper steel splint 4, a lower steel splint, 2 pressing Tighten bolts 6, 4 anchor bolts 5 and 4 glue injection hole bolts 7, two aluminum plates 2 are respectively glued to the upper surface and lower surface of one end of the carbon fiber plate 3, and the end carbon fiber plate 3 is fastened to the upper surface through the anchor bolts 5. In the clamping groove formed by the steel splint 4 and the lower steel splint; the compression bolt 6 fastens the upper steel splint, the end carbon fiber plate 3 and the lower steel splint together, and injects adhesive into the clamping groove through the glue injection hole 7, so that the upper The steel splint 4, the carbon fiber plate 3 glued with the aluminum plate and the lower steel splint a...

Embodiment 2

[0019] The mechanism of the invention is to transmit the stress of the steel connector to the carbon fiber plate through the bonding force between the aluminum plate and the carbon fiber, thereby avoiding the difficulty of mechanically anchoring the carbon plate.

[0020] The card groove formed by the combination of the upper and lower steel splints can hold the aluminum plate at the end of the carbon fiber plate, and at the same time, the end of the carbon fiber plate and the steel connector are integrated by pressing the bolt and adhesive. In this way, through the anchoring and bonding of steel connectors, the anchoring connection of carbon fiber plates can be realized, and its application in prestressed reinforcement and other fields can be developed.

[0021] Bonding of carbon fiber plate and aluminum plate: First, evenly sand the carbon fiber plate with 400-grit sandpaper, then clean the abrasive debris with acetone, and dry it; The aluminum plate is polished, then cleane...

Abstract

The invention provides an anchoring connection device of a carbon fiber reinforced resin base composite material plate. The anchoring connection device comprises two aluminum plates, a carbon fiber plate and a steel connection piece, wherein the steel connection piece comprises an upper steel clamping plate, a lower steel clamping plate, a plurality of pressing bolts, a plurality of anchoring bolts and a plurality of glue injecting hole bolts; the two aluminum plates are respectively bonded on the upper surface and the lower surface of one end of the carbon fiber plate; the carbon fiber plate at the end is fastened in a neck formed by the upper steel clamping plate and the lower steel clamping plate through the anchoring bolts; the upper steel clamping plate, the carbon fiber plate at the end and the lower steel clamping plate are fastened together through the pressing bolts; the neck is injected with an adhesive through glue injecting holes to bond the upper steel clamping plate, the carbon fiber plate bonded with the aluminum plates and the lower steel clamping plate together. The anchoring connection device evenly transfers external stress onto the carbon fiber plate to prevent mechanical stress from being directly applied to the carbon plate to cause uneven stress, transverse rupture and fault anchoring of the carbon plate, so that the anchoring connection reliability of the carbon fiber plate is improved.

Description

technical field [0001] The invention relates to an anchoring connection device for a carbon fiber reinforced resin matrix composite material plate. Background technique [0002] Carbon fiber plate is a new type of high-strength material. For example, its tensile strength can reach 7-10 times that of ordinary steel, and with the advancement of science and technology, the mechanical properties of carbon fiber plate are still improving. In the field of civil engineering applications, carbon fiber panels are often used for external bonding reinforcement of concrete or steel structures to improve the bearing capacity and fatigue resistance of the structure. Applying a certain prestress to the carbon fiber plate can more effectively exert the high strength of the carbon fiber plate and improve the economy of carbon fiber structure reinforcement. However, due to the large modulus, high brittleness, and low transverse shear strength and transverse compressive strength of the carbon...
