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 forming connecting device, an FRP rib bending forming method and an FRP rib material. The connecting device comprises a connecting piece, the two ends of the connecting piece are provided with a first end and a second sleeve respectively, and the first end comprises a casing pipe, a telescopic pipe and a first sleeve which are fixedly connected in sequence. A curing agent capsule and an epoxy resin capsule body are arranged outside the connecting piece, after a telescopic pipe is stretched, the tail end of the first sleeve is arranged onthe second sleeve in a sleeving mode, the telescopic pipe wraps the connecting piece, the curing agent capsule and the epoxy resin capsule body, and a blade is fixed in the first sleeve. By utilizingthe property that a curing agent and epoxy resin glue are cured after being mixed, the curing agent and the epoxy resin glue are separated firstly, and when bending is needed, the blade is driven to move by means of the telescopic performance of the telescopic pipe, so that the curing agent and the epoxy resin glue are mixed to connect and fix FRP ribs broken 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 base materials (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 ...
