Abstract

The invention discloses an FRP stirrup forming device and a method for manufacturing a reinforcement cage. FRP stirrups are made by the FRP stirrup forming device, and the FRP stirrups are bundled into the FRP reinforcement cage. By means of the method, the diameter of the FRP stirrups can be adjusted in real time, the number of fiber bundles can be selected, the condition that the FRP stirrups cannot be connected with longitudinal reinforcements into the reinforcement cage like ordinary steel bars is avoided, the performance of frp materials can be better exerted, the problem about the durability caused by corrosion generated by connecting the FRP stirrups through steel bends is solved, the materials can be uniform materials for the stirrups, and the strength of the FRP composite materials can be better exerted. The reinforcement cage produced by the method is adopted so that simulated results are closer to experimental results, and the test results are more accurate.

Description

technical field [0001] The invention belongs to the field of on-site forming of stirrups, and in particular relates to an FRP stirrup forming device and a method for manufacturing a reinforcement cage. Background technique [0002] The stirrups are located on the outermost side of the concrete structure and are more sensitive to external corrosion. Therefore, the use of corrosion-resistant FRP bars to replace the original steel stirrups can better solve the corrosion problem, making the concrete structure suitable for marine and other severely corroded areas. Environment. [0003] FRP bars are a new type of composite material, which can be used to replace steel bars in concrete structures to solve durability problems caused by steel bar corrosion. The system of the present invention uses FRP stirrups to be formed on site, through FRP fiber bundle winding processing, forming FRP stirrups on site, which can better play the role of stirrups, unlike ordinary stirrups, which nee...
