Japanese Utility Model Application Laid-Open No. 2-109655 according to this prior application is shown in FIGS. 4 and 5, and is composed of two substrates 1 arranged opposite to each other.
・ A rope support body 2 is provided at one end between 1 and the rope pressing body 3 is provided between the substrates 1 and 1 at the position opposite to the rope support body 2.
Is provided so as to be slidable, and a locking portion 25 for connecting a fastening rope is provided at the other end of the substrate 1.1, and the rope is inserted into the rope insertion portion 4 between the rope support body 2 and the rope pressing body 3. The rope holding body 3 is engaged so that the rope is locked in a state in which it cannot be pulled out and the tensioned state is maintained, and the locking is released by the reciprocating movement of the rope holding body 3.

Further, the applicant has filed Japanese Patent Application Laid-Open No. 3-43570 as an invention having the same purpose as the present invention relating to a method of tensioning a master rope using the above-mentioned master rope tensioning metal fitting a '.

In Japanese Patent Laid-Open No. 3-43570 of this prior application, as shown in FIG. 6, a base end of a master rope 26 having a predetermined length is fixed to the left fixing portion 7, and a tip of the master rope 26 is attached to a master rope tensioning metal fitting. It is fixed to the locking portion 25 of a'and the parent rope 26 is attached to the rope insertion portion 4 of this parent rope tensioning metal fitting a '.
The other end of the attachment rope 27 which is shorter than the length of the attachment rope 27 is attached and hung down, the base end of the attachment rope 27 is fixed to the right fixing portion 8, and the other end of the attachment rope 27 hung from the parent rope tensioning metal fitting a '. The master rope 26 can be stretched by pulling the master rope 26 toward the right fixing portion 8 side. Since the length of the master rope 26 is limited, the master rope 26 of that length can only be set between spans of a certain length. Since it cannot be used, it was necessary to prepare a master rope of a predetermined length for each span when using it on a span of a different length.

In order to solve this drawback, the applicant uses two parent rope tensioning metal fittings a'as shown in FIG. 7 in Japanese Unexamined Patent Publication No. 3-43570 and attaches a left attachment rope 27 to the left fixing portion 7. 'The base end is fixed and the other end is fixed to the locking portion 25 of the parent rope tensioning metal fitting a', and the left end of the parent rope 26 is attached to the rope insertion portion 4 opposite to the parent rope tensioning metal fitting a '. Is connected and hung downward, and the other end on the right side of the main rope 26 is fixed to the locking portion 25 of the right parent rope tensioning metal fitting a ′, and the left parent rope tensioning metal fitting a ′. The other end of the master rope 26 inserted into the main rope 26 is adjusted to adjust the tension length of the master rope 26, and the right side rope 2 is attached to the rope insertion portion 4 opposite to the right mother rope tensioning metal fitting a '.
The other end of 7 is inserted and connected and hung down, the base end of this attachment rope 27 is fixed to the right fixing portion 8, and the other end of the attachment rope 27 is pulled to the right fixing side 8 to stretch the parent rope 26. However, in this case, since two parent rope tensioning metal fittings a '・ a' were used, handling is inconvenient and the parent rope 26 that adjusts the stretched length of the parent rope 26 according to the span is used.
Since the pulling direction of the other end on the left side of the rope pulls toward the central direction between the spans, it is unstable due to the relationship of the scaffolding, and the other end of the rope on which the parent rope 26 is stretched during handling is wrong. There was a fear.

The present invention solves the above-mentioned drawbacks and provides a rope tensioning metal fitting and a rope tensioning method capable of tensioning a master rope in a stable posture even if the span length is different.
