Abstract

The invention discloses an FRP rib bending connection device on a construction site, and a bent FRP rib member preparation method. The FRP rib bending connection device comprises a corrugated pipe, afirst sleeve and a second sleeve are connected to the two ends of the corrugated pipe correspondingly, a first through hole used for allowing FRP ribs to penetrate is formed in the first sleeve, a second through hole used for allowing FRP ribs to penetrate is formed in the second sleeve, the first through hole and the second through hole communicate with the corrugated pipe, a glue outlet hole isformed in the first sleeve, a glue injection hole is formed in the second sleeve, the glue outlet hole communicates with the glue injection hole through the corrugated pipe, and the glue injection hole is used for being connected with a glue injection pipe of a glue injection machine. Bending of the connection device at different angles can be achieved, the corrugated pipe and the sleeves can serve as containers, epoxy resin is injected into the corrugated pipe, the first sleeve and the second sleeve through the glue injection hole, and after the epoxy resin is solidified, FRP rib members which are bent to the certain angle can be obtained.

Description

technical field [0001] The invention belongs to the technical field of FRP tendon connection, and in particular relates to an FRP tendon bending connection device at a construction site and a preparation method for a bent FRP tendon member Background technique [0002] FRP bar material (referred to as FRP bar) has the advantages of light weight, high strength, corrosion resistance, low electrical conductivity, designable performance, and similar linear expansion coefficient to cement concrete, etc., especially suitable for structures in water conservancy projects, seaport projects and chemical corrosion environments engineering etc. [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 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 stirrups. Mos...
