FRP-MADE MAIN ROLLER AXLE PRESSING PLATE OF ROLLER GATE, MAIN ROLLER AXLE, MAIN ROLLER AXLE SUPPORTING PLATE, MAIN ROLLER, SIDE ROLLER, SIDE ROLLER AXLE, SIDE ROLLER AXLE SUPPORTING PLATE AND THEIR MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To further promote light weight and a low cost of a roller gate by using an FRP-molded body by the hand lay up method also for an FRP-made component of the roller gate to which high stress is loaded. SOLUTION: The FRP-made main roller 3 is rotatably attached to a non-rotatable FRP-made main roller axle 4 and is horizontally supported by two FRP-made main roller axle supporting plates 5 each secured to a FRP-made vertical beam material 13 with a bolt. An FRP-made main roller axle pressing plate 6 preventing a rotation is fitted in and fixed to a cut provided at the other end of the FRP-made main roller axle 4. The main roller axle supporting plate 5, the main roller axle pressing plate 6, a skin plate 7, a rubber pressing plate 8, a side roller 10, a side roller axle 10a, a side roller axle supporting plate 11, the vertical beam material 13, a lateral beam material 14 and a gusset plate 15 are GFRP-molded bodies. On the other hand, only the main roller 3 and the main roller axle 4 are CFRP-molded bodies since higher stress is given to them. COPYRIGHT: (C)2007,JPO&INPIT
