るめてケーブル2との連結を解いていた。Conventional technology In a rockfall protection shelf where a terminal column is installed in parallel at both ends and an intermediate column is placed in the middle, and a cable is stretched between these, the cable is usually connected at one end to the terminal column and then directed toward another terminal column. While tensioning, U-bolts are used to temporarily fasten the intermediate struts one after another, and finally they are attached to the terminal struts on the above side. Conventionally, when attaching to the terminal struts, the following work was performed. was. To explain this based on Fig. 2, the end of the row 1 extending from the chain block (not shown) is attached to the cable 2, and the cable 2 is temporarily tensioned by hoisting the chain block. The cable is tightened by passing the connecting bolt 4, which is connected to the two ends via the cable end fitting 3, through the bolt insertion hole of the terminal support 5, and screwing the nut 6 into the protruding end of the bolt, and then tightening the cable. I lowered the block, loosened row 1) and disconnected it from cable 2.

部品数を減らすことを目的とする。Purpose of the Invention The present invention relates to tensioning the cable by connecting the cable near the end of the cable to a chain block or other boosting device, passing the free end of the cable through a terminal support, and attaching a cable end fitting to the end protruding from the support. It is designed to function as an installation and stopper, and allows the cable to be connected to the terminal support with a single tensioning operation.It also eliminates the need for connection bolts, thereby improving work efficiency. The purpose is to reduce the number of parts required for connection.

出端部に索端金具16を取りつける。Example As in the conventional case, one end of the cable 1) is attached to one of the two terminal columns of the cable, temporarily fastened in order at the intermediate column, and then connected to another terminal column 12 by first using a chain block (not shown). Attach the end of the rope 13 that stretches further to the fixing bracket 14 fixed near the free end of the cable 1), and wind up the chain block to remove the cable 1.
) to make it tense. Next, the free end thereof is passed through the cable insertion hole 15 formed at the end post opening, and the cable end fitting 16 is attached to the end projecting from the post.

僅かであり、支障を生じない。The end fittings are known and the attachment is conventional. That is, the free end of the cable protruding from the end support 12 is passed through the socket 17, the cable 1) is untwisted and untwisted, the wedge 19 is driven in and fixed, and the cap 18 is fitted and screwed onto the socket. Before and after attaching the cap 18, the chain block is unwound, the rope 13 is loosened, and the end of the rope attached to the fixing fitting 14 is untied. As the rope 13 slackens, the tension at the free end of the cable increases, but the socket 17 and cap 1
At least one of 8 is pressed against the terminal support 12 and functions as a stopper and is fixed.After being fixed in the above manner, the socket or the cap pressed against the terminal support 12, or both. However, in order to reduce this stress, it is desirable to make the contact with the terminal strut as large as possible by, for example, making the shape of the cap a truncated cone. 1) When 3 is loosened, the cable end fitting is pressed against the terminal support, and the tension on cable 1) is also slightly loosened as the slack at the free end is absorbed, but this slack is slight and does not cause any problems. .
張設後の張力が所望値になるようにするには弛みを見込
んで予めロープによる張力をやや強めにしておけばよい
。In order to ensure that the tension after tensioning reaches the desired value, it is sufficient to make the tension of the rope a little stronger in advance in anticipation of slack.

い。In the above embodiment, one end (not shown) is attached to the terminal support in the same manner as in the conventional case, but one end of the cable is passed through the terminal support, and the cable end is fixed to the protruding end. It may also be attached to a support in the same manner.
