Abstract

The invention discloses an FRP tendon bending connection device on a construction site and a preparation method for a bent FRP tendon member. The first sleeve is provided with a first through hole for passing through the FRP tendon, and the second sleeve is provided with a second through hole for passing through the FRP tendon, and the first through hole and the second through hole are evenly spaced. It communicates with the bellows, the first sleeve is provided with a glue outlet, the second sleeve is provided with a glue injection hole, the glue outlet and the injection hole are connected through the bellows, and the injection The glue hole is used to connect with the glue injection pipe of the glue injection machine. It can realize the bending of the connection device at different angles. The bellows and the sleeve can be used as containers, and the epoxy resin can be injected into the bellows, the first sleeve and the second sleeve through the injection hole, and the epoxy resin can be solidified The FRP tendon member bent into a certain angle is 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...
