Title:
REINFORCEMENT HOLDING DEVICE FOR GAS PRESSURE WELDING
Document Type and Number:
Japanese Patent JP2016211302
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a reinforcement holding device for gas pressure welding that prevents slipping of a reinforcement held by the reinforcement holding device while setting for pressure welding or during pressure welding of the reinforcement.SOLUTION: A shaft center CB1 of a tightening bolt 38 of a first reinforcement holding device 26 is inclined toward a side away from a second reinforcement 12b, while a shaft center CB2 of the tightening bolt 38 of a second reinforcement holding device 28 is inclined toward a side away from a first reinforcement 12a. As such, the tightening bolt 38 bites into the first reinforcement 12a and the second reinforcement 12b to enhance fastening force. The configuration appropriately prevents slipping of the first reinforcement 12a and the second reinforcement 12b at the portion tightened by the tightening bolt 38, during setting and pressure-welding of the reinforcement.SELECTED DRAWING: Figure 6
