Document Type and Number:
Japanese Patent JP2020070574
Kind Code:
A
Abstract:
To provide a technology for preventing a construction error of a tight frame capable of easily and surely preventing a laterally asymmetric tight frame, especially a seam type tight frame from being constructed in the opposite direction.SOLUTION: A tight frame 10 is provided with construction error prevention mechanisms 12 at positions where a center part in a width direction of a connecting end part 11 connected to an adjacent tight frame 10 is removed. When the connecting end parts 11 of the tight frames 10 are connected to each other, the construction error prevention mechanisms 12 display an integrated marking (in this case, the perforations of ○) visible to a constructor.SELECTED DRAWING: Figure 2
