Description

[Detailed description of the invention] This invention relates to a rail attachment device installed on power transmission towers, telephone poles, and other high-rise structures to prevent workers from falling at heights.

Conventionally, this kind of product was long enough to clamp both edges of the angle material between the drops, so when a load was applied to the object to which it was attached, the clamping part loosened and the problem was that the force would sag. there were.

Therefore, the purpose of this project is to eliminate and improve upon the shortcomings of such conventional products, to provide a durable fixture that is easy to install and does not loosen or wear after tightening. .

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

This embodiment consists of a mounting plate with elongated holes 1 and 2 at both ends and a bolt insertion hole 3 in the center, a pole l-6 into which a hook body 5 is inserted, a nut 7, and an approximately U-shaped mounting plate. Consisting of a bolt 10 into which a backing material 8 and a presser plate 9 are fitted, and a nut I/11, the bolts I to 6 are inserted into the bolt insertion holes 3 provided at the center of the mounting plates 1 to 4, and the bolts 6 are hooked. After inserting the body 5, screw the nut 7 into the elongated hole 2 provided at one end of the mounting plate 4.
Insert the bolt 6 into which the backing material 8 is inserted, and then insert the holding plate 9 into the bolt 6. Fit the mounting plate 4 and the holding plate 9 into both approximately U-shaped pieces of the backing material 8. It has a structure in which the bolts 10 and 11 are screwed together in the fitted state.

To attach the mounting tool of the present invention to the angle material 12 of a steel tower, etc., first apply the mounting plates 1-4 and poles 6, which are provided orthogonally to each other, to both sides of the angle material 12 on the open side, and then fit them onto the bolts 6. Hang the inserted hook body 5 on one side edge of the angle material 12 and leave it!・Tighten with 7.

On the other hand, when the nut 11 is tightened with the backing material 8 fitted on the bolt 10 inserted into the elongated hole 2 of the mounting plate 4 in contact with the other side edge of the angle material 12, the retaining plate 9 and the mounting plate 4 One side of the material 12 can be clamped and fixed.

After that, the long hole 1 provided at the other end of the mounting plate 4 is
Another connecting member, such as a connecting bolt 15 or a collar 16, is attached to the rail 13 to hold the rail 13 in place.

The rail 13 attached to a high place such as a steel tower in this way
The safety device 14 is fitted to the safety device 14, and the worker connects the robe or hook of the safety belt worn on the body to the safety device 14, and ascends, descends, or moves laterally on a high-rise structure such as a steel tower.

If a worker slips and falls during this movement, the worker should be restrained by safety belts, safety devices, rails, attachments, etc. to prevent the worker from falling.

The present invention is constructed as described above, and a backing material 8 is provided on one end side of the mounting plate 4, and both U-shaped pieces of the material 8 are on the sides of the angle material 12 on both sides of poles I to 10. Since the structure is such that the nut 11 is tightened while it is in contact with the edge, the presser plate 9 presses and clamps the angle member 12.
Even if a high load is applied to one end side of the mounting plate 4 on which the rail 13 is attached, the pole NO side can be securely fixed without being worn.

In addition, the present invention is provided with a backing material 8, and the material 8 is shaped like a U-shape so that its two pieces loosely sandwich both side edges of the holding plate 9, so that when tightening the nut 11, Since the presser plate 9 does not rotate together with the nut 11, attachment to the angle member is easy and can be securely fixed.

In addition, since the long holes 1 and 2 are provided at both ends of the mounting plate 4, the present invention has practical effects such as easy mounting according to the size of the mounting angle material 12 and the mounting position of the rail 13. .
