Description

[Detailed Description of the Invention] The present invention relates to a mounting bracket used when attaching a wire rope to a support in a rockfall protection fence, a guard cable, or the like.

Conventionally, as shown in Fig. 1, wire rope attachment fittings used for rockfall protection fences, etc. are conical fittings with a plurality of concave grooves 4 in the axial direction in a tapered fitting hole 2 in a socket 1. Kotter 3
The wire rope 5 is inserted into the concave groove 4 of the cotter 3 by untwisting and fitting the net 5a of the wire rope 5, thereby sandwiching the net 5a between the inner wall surface of the fitting hole 2 and attaching it to the column. It is known that a cap-shaped connecting member 7 provided on a mounting rod 6 for mounting is attached to a screw 8 provided on the outer periphery of the rear end of the socket 1.

However, in the conventional wire rope mounting bracket, the connecting member 7 of the mounting rod 6 is attached to the outer periphery of the socket 1, so that the rod 3 is inserted deeply into the fitting hole 2 as shown in the figure. If it is separated from the connecting member 7, there is a risk that when a large external force is applied to the wire rope 5, the cotter 3 will move within the socket 1, causing the wire rope to loosen or come off from the socket.

The purpose of the present invention is to provide a mounting bracket that solves the above-mentioned conventional problems. A connecting member provided in the connecting member is screwed into the connecting member so as to be freely advanced and retractable, and a tightening portion is provided at the tip of the connecting member to abut and press the above-mentioned cotter, thereby making it possible to securely attach the wire rope. It is characterized by:

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. Fig. 2 illustrates the case where the present invention is applied to a rockfall protection fence, where 10 is a post located at the end of the fence; 12 is a mounting bracket that connects the end of the wire rope 11 to the above-mentioned support 10; 13 is a diamond-shaped wire mesh stretched between each support; As is clear from Figures 3 and 4,
It is constructed by twisting a large number of steel wires together to form a plurality of child nets 11a, and twisting these child nets 11a together.

In addition, the mounting bracket 12 has small diameter openings 15 at both ends.
a hollow socket 14 having a tapered fitting hole 17 between the large-diameter opening 16 and the large-diameter opening 16;
The conical connector 1 inserted into the fitting hole 17 of
8 and a mounting rod 19 equipped with a nut 20 for attaching it to the pillar 10, and around the rod 18, there is a net 11 of the wire rope 11.
A plurality of concave grooves 21 are cut in the axial direction at regular intervals for fitting the mounting rod 19, and a connecting member 22 with a thread cut around the periphery is integrally provided at one end of the mounting rod 19. The member 22 is attached with a screw 16a on the inner peripheral surface.
The connecting member 22 is screwed into the large-diameter opening 16 of the socket 14, and the connector 1 is attached to the tip of the connecting member 22.
A tightening portion 23 is formed which abuts against the rear end of 8 and presses it toward the small diameter opening side.

When connecting the end of the wire rope 11 to the mounting bracket 12, the mounting rod 19 and the rope
8 is removed, insert the end of the wire rope 11 into the socket 14 through the small diameter opening 15, untwist the wire rope 11 to separate the child nets 11a from each other, and transfer the separated child nets 11a to the cotter 18.
The connector 1 is fitted into the concave groove 21 of the connector 1.
8 into the fitting hole 17 of the socket 14, thereby connecting the concave groove 21 of the socket 18 and the socket 14.
After that, the connecting member 22 of the mounting rod 19 is screwed into the large diameter opening 16 of the socket 14, and the connecting member 22
The rear end of the cotter 18 is pressed by the tightening portion 23 .

When screwing in the connecting member 22, the socket 14
A pair of flat parts 24 facing each other on the outer surface of the rear end.
At the same time, a similar flat part 25 is also provided on the mounting rod 19, and if these flat parts 24 and 25 are held and screwed with a tool such as a wrench, the installation work can be simplified. This can be done extremely efficiently and robustly. In addition, the socket 14
There are three pairs of flat parts 24 on the outer circumferential surface of the
It may also be formed into a square shape.

According to the wire rope attachment fitting of the present invention constructed as described above, the connecting member of the attachment rod is screwed into the inside of the large diameter opening of the socket, and the end face of the rope rod is pressed by the tightening portion of the connecting member. As a result, the cotter can be firmly held in the socket simply by screwing the connecting member into the socket, thereby making it possible to securely attach the wire rope.

In addition, the above-mentioned socket has a simple tapered fitting hole inside and a thread cut on the large diameter side, so its shape and structure are very simple. The production of molds and casting work during casting can be significantly simplified, and since the connecting member for screwing into the socket is integrally formed on the mounting rod, the structure of the entire mounting bracket is simplified. This minimizes the number of parts and makes it extremely easy to attach and detach the wire rope. In particular, when installing rockfall protection fences, guard ropes, etc., many wire ropes must be strung at once, so by simplifying the work on the mounting brackets as described above, the overall work time can be reduced. can be significantly shortened.

Furthermore, since the connecting member of the mounting rod is screwed into the inside of the socket, it is possible to provide a flat part on the outer surface of the socket for hanging a wrench, and this flat part can be used to tighten the socket with a tool. The connection between the mounting rod and the mounting rod can be made extremely easily and firmly.
