Description

TECHNICAL FIELD

[0001] The application relates to the technical field of FRP stirrups, in particular to a device for producing FRP stirrups. BACKGROUND

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

[0003] The traditional production process of FRP stirrups is as follows: after a plurality of fiber bundles pass through a glue tank, the excess resin is removed and the fiber bundles are flattened through a glue scraping port and a flattening device, then the fiber bundles are arranged and wound layer by layer on the surface of the mold through the rotation of the mold, and the fiber is parallelly wound through horizontal translation while the mold is rotating. After winding is completed, the mold and the stirrup wound on the surface thereof are placed in an oven for curing and forming. After curing, the mold is removed, and an FRP winding pipe is obtained, which is then cut into the required size and shape according to the product size.

[0004] The existing stirrup production technology adopts manual production of production molds, adjustment of mold sizes and demolding of completed products, which has low production efficiency and the molds cannot be reused.

[0016] The first end and the tail end of the center rod are threadedly connected with two nuts, and the nuts at the same end are respectively abutted against the synchronous rods at the upper end and the lower end of the center point.

[0017] Through the above technical solution, the displacement of the center rod and the demolding pipe can be effectively limited, and the connection stability of the synchronous rod and the center rod is strengthened.

[0018] Further, a scale mark is arranged on the linear slide rail.

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

[0020] Further, a hand screw is arranged on each sliding block, and a screw rod of the hand screw penetrates the sliding block and is attached to the linear slide rail.

[0021] Through the above technical solution, the hand screw can effectively fix the sliding block, avoiding displacement of the center rod during processing.

[0025] S3, after winding is completed, remove any side of the rotating plate, remove the four demolding pipes together with the reinforcement on the surface of the demolding pipe from the center rod, and then put the demolding pipe and the reinforcement on the surface of the demolding pipe into the oven for curing and forming; after the demolding pipe is removed, a new demolding pipe without winding fiber bundle can be replaced to continue winding and realize continuous production;

[0026] S4, after curing in step S3, FRP continuous winding reinforcement is obtained, and cutting is performed according to product size requirements.
