Carbon fiber plate anchor with corrugated plywood and soft backing plate

Abstract

The invention discloses a carbon fiber plate anchor using a corrugated splint and a soft backing plate, comprising an upper splint and a lower splint for clamping a carbon fiber plate, the middle of the upper splint and the lower splint is a carbon fiber plate, the upper splint The side of the plywood in contact with the carbon fiber plate is designed as a wave surface, and a groove is drilled on the side of the lower plywood in contact with the carbon fiber plate, and a soft backing plate is filled in the groove, and the upper plywood and the lower plywood are Corresponding bolt holes are opened respectively, and bolts for clamping the upper splint and the lower splint are inserted into the bolt holes. The invention has high working reliability, simple manufacturing process, low cost, good economy, simple operation and good applicability; it has a wide range of applications and can be used not only as a clamp and anchor for composite material sheets, but also as a composite material sheet It can be widely used in the reinforcement and reinforcement of bridge structures and large-span space structures, and can also be used for the overall reinforcement of prefabricated floors and brick walls to improve seismic safety.

Description

technical field [0001] The invention relates to the field of civil engineering reinforcement and reinforcement, in particular to a carbon fiber plate anchorage using a corrugated splint and a soft backing plate. Background technique [0002] In recent years, high-strength composite fiber materials such as carbon fiber boards have been widely used in the reinforcement field of civil engineering. Carbon fiber panels are usually pasted on the surface of concrete components to improve the strength of the components. If the carbon fiber plate is stretched and then anchored to the surface of the reinforced member, the bending strength and crack resistance of the reinforced member can be improved, the use efficiency of the composite fiber material can be improved, and the reinforcement cost can be reduced. [0003] The use of prestressed reinforcement technology requires tensioning and anchoring of carbon fiber sheets. Although carbon fiber sheets have high tensile strength, their...

Problems solved by technology

[0003] The use of prestressed reinforcement technology requires tensioning and anchoring of carbon fiber sheets. Although carbon fiber sheets have high tensile strength, their shear resistance is poor and it is not easy to anchor

Relying on the traditional surface friction to realize the clamping and anchoring of the carbon fiber plate, it is prone to clamping and slipping, and its working reliability is poor
