Abstract: PROBLEM TO BE SOLVED: To stably execute an anchoring work of FRP reinforcements by fixing the FRP reinforcement so as to wrap up the outer peripheral face of the holding part of the reinforcement when introducing a tension to the FRP reinforcement to anchor it while pinching the reinforcement by an anchoring tool including a pair of wedge members and holding it. SOLUTION: An external case 1, wedge parts 2, 2', and FRP reinforcements 3 are provided. The wedge parts 2, 2' slide along the internal wall of the external case 1 by the tension at the time of anchorage, and the FRP reinforcements 3 are held on tensing the reinforcements. The FRP reinforcement 3 is constituted of reinforcing members 4, 4' and an adhesive to fix the reinforcement 3 and the reinforcing members 4, 4'. In this way, since the anchorage part of the reinforcements 3 is covered and reinforced, when a tension is introduced to the FRP reinforcement, crushing at the holding part can be prevented and the FRP reinforcement is not directly held by the wedge members. Accordingly, the reinforcement does neither slip out of the holding part nor breaks at the front end of the wedge and hence, construction work can be carried out while imparting a stable tension.

Abstract: PROBLEM TO BE SOLVED: To resolve a weak twisting deformation, reduce a bending deformation and an own weight bending at the time of mounting a thin-plate workpiece, and improve reception efficiency, by a method wherein a thin-plate workpiece conveying hand is formed of a fiber reinforcing plastic member and a metal. SOLUTION: In a conveying hand, a hand detect part 5 and a hand base part 7 are formed of a fiber reinforcing plastic part composed of a carbon fiber and a thermosetting resin. Further, a curve part 7 for joining the hand detent part 5 to the hand base part 6 is formed of a metal composed of an aluminum alloy, a titanium alloy and the like. A twisting stiffness which is a weak point for a thermosetting member composed of a carbon fiber and a thermosetting resin is reinforced. Accordingly, even in the conveying hand of any forms, it is possible to reduce an own weight and a deformation amount of bending when mounting a thin-plate workpiece. As the result, it is possible to remarkably decrease a thin-plate workpiece mounting pitch of a cassette.

Abstract: PROBLEM TO BE SOLVED: To obtain a uniform and good bonded state in a laminated surface, in laminating first and second base material through a laminating material, by together using pressure due to substantially uniform surface pressure and pressure due to high surface pressure in a peripheral edge part. SOLUTION: When the operation switch 16 of a pressure laminating machine 1 is operated after a laminated product 8 is set on a receiving stand 9, air- pressure PA is supplied to the upper part of a cylinder 4 and the top plate 4 fixed to a rod 4' falls and a uniform pressure fixed form material 11 or a frame material 13 approaches the upper surface of the first base material 5 of the laminated product 8. Next moment, the peripheral edge part of the laminated product 8 is held to surface pressure higher than that of other part by a frame material 13 and lamination advances. A part other than the peripheral edge part is elastically deformed on the upper surface of the base material 5 in such a form that the fixed form material 11 conforms to the wall thickness change of a second base material and uniformly pressed in a state slightly lower than the peripheral edge part in surface pressure and lamination advances.
