Description

Technical Field

[0001] The present application relates to the technical field of FRP stirrups, and more specifically, to a device and process for producing FRP stirrups. Background Art

[0002] Fiber reinforced polymer (FRP) is widely used in various fields due to its advantages of light weight, high strength, fatigue resistance, insulation, heat insulation, corrosion resistance, good elasticity, designability and easy processing. FRP stirrups can reasonably replace steel stirrups in concrete structures due to their good durability.

[0003] The production process of FRP stirrups is to pass multiple fiber bundles through the dipping tank, remove excess resin and flatten the fiber bundles through the scraping port and flattening device, and then arrange the fiber bundles layer by layer and wrap them on the surface through the rotation of the mold. The mold realizes parallel winding of the fibers through horizontal translation while rotating. After winding, the mold and the reinforcement material wrapped on its surface are placed in an oven for curing and forming. After curing, the mold is removed to obtain the FRP winding tube, which is then cut into the required size and shape according to the product size requirements.

[0004] The existing stirrup production technology adopts manual production of production molds, adjustment of mold sizes and demoulding of finished products, which results in low production efficiency and non-reusable molds.

[0005] To this end, the present application proposes a device and process for producing FRP stirrups to solve the above-mentioned problems. Summary of the invention

[0013] The center rod is sleeved with a demoulding tube.

[0016] The first and second ends of the center rod are both threadedly connected with two nuts, and the nuts at the same end respectively abut against the synchronization rods at the upper and lower ends of the center point.

[0017] Through the above technical solution, the displacement of the center rod and the demoulding tube can be effectively limited, and the connection stability between the synchronization rod and the center rod can be enhanced.

[0018] Furthermore, the linear slide rail is provided with a scale mark.

[0019] Through the above technical solution, the setting of the scale mark makes the adjustment of the mold size more intuitive and accurate, reducing errors in production.

[0022] S2. Use a driving device to drive the rotating shaft, either vertically or horizontally, and arrange it according to actual production needs; continuously and evenly wind multiple fiber yarns impregnated with resin on the outside of four demoulding tubes to form a continuous fiber preformed bundle;

[0023] S3. After winding is completed, remove the rotating plate on either side, separate the four demoulding tubes together with the ribs wound on their surfaces from the central rod, and then put the demoulding tubes and the ribs on their surfaces into an oven for curing and forming; after the demoulding tubes are removed, they can be replaced with new demoulding tubes without ribs wound around them, and continue winding to achieve continuous production;

[0024] S4. After solidification in step S3, an FRP winding tube is obtained. According to the product size requirements, the FRP winding tube is cut along the direction parallel to the fiber winding to obtain FRP stirrups.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] (1) Through modular design, rapid adjustment and precise control of mold size are achieved, improving production efficiency and product quality;
