Problems solved by technology

However, some FRP bars have low plasticity and cannot be bent. Therefore, for the various sizes of FRP bars required on the construction site, the current market does not have a very accurate regulation on the connection of FRP bars. Most of them are spliced ​​and tied, which cannot be fully utilized. Strength of FRP bars

Abstract

The invention discloses a prefabricated on-site bending and forming connection device, an FRP bar bending and forming method, and an FRP bar, wherein the connecting device includes a connecting piece, and the two ends of the connecting piece are respectively provided with a first end and a second sleeve , the first end includes a sleeve, a telescopic tube and a first sleeve fixedly connected in sequence, and a curing agent capsule and an epoxy resin capsule are arranged on the outside of the connecting piece. After stretching the telescopic tube, the first sleeve The end of the sleeve is put on the second sleeve, and the telescopic tube wraps the connecting piece, the curing agent capsule and the epoxy resin capsule body. The blade is fixed in the first sleeve, and the curing agent and the epoxy resin glue are mixed and cured. First separate the curing agent and epoxy resin. When bending is required, the expansion and contraction properties of the telescopic tube are used to drive the blade to move, so that the curing agent and epoxy resin glue are mixed to connect and fix the broken FRP bars due to bending.

Description

technical field [0001] The invention belongs to the technical field of FRP steel bars, and in particular relates to a prefabricated on-site bending and forming connection device, an FRP bar bending and forming method, and FRP bars. Background technique [0002] FRP bars are formed by extruding and drawing multiple strands of continuous fibers (such as glass fibers, carbon fibers, etc.) through a base material (such as polyamide resin, polyethylene resin, epoxy resin, etc.) FRP steel bar material has the advantages of light weight, high strength, corrosion resistance, low electrical conductivity, designable performance, and similar linear expansion coefficient to cement concrete. It is especially suitable for structural engineering in water conservancy projects, harbor projects, and chemical corrosion environments. [0003] Now FRP bars are more and more used in engineering, and their use value is gradually increasing. However, some FRP bars have low plasticity and cannot be...
