Embodiment 1
[0038] The processing method of prefabricated assembly system FRP composite building material fastening closed stirrups is characterized in that the FRP material is combined through a composite hinge plate and a composite hinge groove, and the iron wire of the iron wire coil is formed through the FRP rib forming tube and the FRP rib outlet plate As the inner core, it is dried in an oven and ventilated and cooled by a blower to form an FRP composite building material buckled and closed spiral stirrup wire. Design drawings require binding.
[0039] Include the following steps:
[0040] (1) Dipping: Evenly distribute the FRP material and impregnate it in the resin by pultrusion process;
[0041] (2) Preforming: The FRP material processed in step (1) is divided into several Φ0.6mm fiber bundles through a composite hinged wire plate, of which 6 fiber bundles are compounded through a composite hinged wire groove, and then combined with iron wire coils through FRP Rib-forming tubes...
Embodiment 2
[0049] A processing method for fastening closed stirrups of prefabricated assembly system FRP composite building materials, comprising the following steps:
[0050] (1) Dipping: Evenly distribute the FRP material and impregnate it in the resin by pultrusion process;
[0051] (2) Preforming: The FRP material processed in step (1) is divided into several Φ0.6mm fiber bundles through a composite hinged wire plate, of which 6 fiber bundles are compounded through a composite hinged wire groove, and then combined with iron wire coils through FRP Rib-forming tubes and FRP rib outlet plates are formed into inner cores, and 12 resin-impregnated fiber bundles are covered outside the inner cores, and then the fibers are wound outside to obtain FRP composite blanks;
[0052] (3) Semi-cured drying: The FRP composite blank processed in step (2) is dried in an oven at a temperature of 100°C for 10 minutes, and the FRP and iron wire are heated, and composited by hinged winding to form a semi-...
Embodiment 3
[0059] A processing method for fastening closed stirrups of prefabricated assembly system FRP composite building materials, comprising the following steps:
[0060] (1) Dipping: Evenly distribute the FRP material and impregnate it in the resin by pultrusion process;
[0061] (2) Preforming: The FRP material processed in step (1) is divided into several Φ0.6mm fiber bundles through a composite hinged wire plate, of which 6 fiber bundles are compounded through a composite hinged wire groove, and then combined with iron wire coils through FRP Rib-forming tubes and FRP rib outlet plates are formed into inner cores, and 12 resin-impregnated fiber bundles are covered outside the inner cores, and then the fibers are wound outside to obtain FRP composite blanks;
[0062] (3) Semi-cured drying: The FRP composite blank processed in step (2) is dried in an oven at a temperature of 90°C for 7 minutes, the FRP and iron wire are heated, and composited by hinged winding to form a semi-cured ...
