Therefore, the various facilities are scattered all over the country, and a highway network and a railroad network for transporting goods and things are laid in the networks scattered all over the country, and it is still still in use. The roads and railway networks have been renovated and new ones have been laid in order to smoothly use the seed transportation.

[0003] When laying the above-mentioned expressway or railroad network, it is necessary to excavate and lay the mountain forest area existing at the site, but a slope is formed and formed at least on one side or the like in the excavated portion. However, in order to maintain the formation of the slope, it is necessary to construct a free claim or the like on the slope of the slope, or to perform predetermined construction work such as weeding or soil retaining work.

In order to perform various constructions on the slope, as shown in FIG. 8, a dog running 2 is formed in a predetermined span in a horizontal direction through a predetermined pitch in a vertical direction of the slope 1, and The main rope 3

Tightens a safety belt on the body as shown in FIG.
An auxiliary rope 7 is attached to the belt 6 from the back, and an anchor hook 8 is attached to the auxiliary rope 7 so that the anchor hook 8 is engaged with the main rope 3 so as to be freely detachable. Down the main rope 3 (Fig. 1
At 0, the back side), various construction works such as free claim and weeding are performed, and the various constructions on the slope 1 of the main ropes 3, 3 are carried down to the dog running 2 along the main ropes 3. Then, the dog running 2 is moved in the lateral direction so that the anchor hook 8 on the back is disengaged from the other main rope 3 adjacent thereto, and the predetermined lifting operation is transmitted again in a zigzag manner as shown by the arrow A in FIG. They had to move and do construction work.

[Problems to be solved by the invention]

[0005] Therefore, in order to perform various constructions on the slope 1 between the main ropes 3, 3, 3, each time,
There is a trivial drawback that it is necessary to descend to the dog running 2 along the main rope 3, and to move up and down the dog running 2 along the adjacent main rope 3 to perform the work. In addition, the safety belt 5 including the anchor hook 8 has a considerable amount of weight, which disadvantageously impairs safety.

[0006] Unexpectedly, if one forgets to release and retighten the anchor rope 8 from one of the anchor hooks 8 to the other main rope 3, there is a very serious problem in the safety of construction work.

[0007]

SUMMARY OF THE INVENTION The object of the invention of this application is to provide a technical object to solve the problem of hindering the construction efficiency of a safety belt based on the above-mentioned prior art, and to maintain the construction level between adjacent main ropes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following is a description of embodiments of the present invention as embodiments of the present invention, with reference to FIGS. 1 to 7. FIG. The eighth
Parts that are the same as those in the figures below will be described using the same reference numerals.

As shown in FIG. 1, (a) and (b) of FIG.
(B) is formed on one side surface of an unillustrated highway or the like, and a dog running 2 is formed in the vertical direction through a predetermined span, for example, every 5 m in a horizontal direction. Are provided so that the main ropes 3, 3... Cross the dog running 2 at a predetermined span in the lateral direction via an anchor 9, and run. 2 (c) and 2 (d), the auxiliary belt 7 is attached to the safety belt 5 by crossing the safety belt 5 attached thereto with the belt 6 so that the whole body is connected to the safety belt 5. Therefore, as shown, the main rope 3 is connected to a temporary fixing member 10 of the E type shown in FIG.
And a lock fitting 11 such as a pin type is inserted into the temporary fixing fitting 10 via the lock pin 12 and locked to the protrusions 10 ′ and 10 ″ at both upper and lower ends.
As shown in FIG. 2 (a), the main rope 3 is inserted in an S-shape as shown in FIG. It has been made possible.

Therefore, the safety belt 5 is of a shoulder type, and the worker 4 is suspended in a forward posture with respect to the main rope 3 in a whole body via a belt to be in a locked state. To be able to do it.

It is not necessary for the safety belt 5 to hold the entire weight of the worker 9, but safety is assured so that the safety belt 5 has a proof strength about five times that of the worker.

Therefore, unexpectedly, during the construction work, even if the hand is released from the main rope 3, it is locked and does not fall suddenly during the construction work. Various operations are performed.

When performing various constructions over the entire slope 1, the worker kicks and swings the slope 1 to change the saddle 1 to the adjacent main rope 3 as shown by an arrow in FIG. Then, the adjacent main rope 3 is grasped forward by hand, and the
Saddle change can be performed easily at the same construction level while maintaining the forward posture, and forward construction can be performed smoothly at the same construction level without lateral movement using dog running 2 in a U-shape. In this manner, various constructions on the entire slope 1 can be smoothly performed.

Further, the lock fitting 11 is removed from the two projections 10 ', 10 "with respect to the main rope 3 at the original position where the main rope 3 was previously locked and fastened to the temporary fastening fitting 10 in the tightened state, and then removed. Thereby, the temporary fixing fitting 10 is set in the release position, and the original main rope 3 is removed. In the meantime, the E-shaped tightening projections 10 ', 1
0 ″ is inserted, the hooking pin 11 is inserted, and the adjacent main rope 3 is set to the insertion posture by the pin 11.

During this time, the worker moves up and down
The gripping can be performed by hand-gripping through the fastening of the temporary fixing metal 10 against the main rope 3, and even if the end of the hand is accidentally removed from the main rope 3, the E-shaped tightening of the temporary fixing metal 10 can be performed. An emergency stop is performed by the locking of the tightening action, and the anti-slip action can be performed safely.

In this case, the proof strength of the temporary fixing fitting 10 is designed so as to hold the entire weight of the worker 4.

Of course, when changing the main rope 3 from the adjacent main rope 3 to the adjacent main rope 3, the pin 11 of the temporary fixing metal fitting 10 is removed from the projections 10 ', 10''via the cord 12, and the main rope 3 is removed. Can be detached from each of the projections 10 ′, 10 ″, and the tightening can be repeated so that the posture can be smoothly performed in a more forward posture.

It should be noted that the embodiments of the invention of this application are not limited to the above-described embodiment. For example, as in the case of a safety belt for an automobile, a safety belt V series lock fitting is an E type tightening temporary fixing fitting. Instead of 10, it can be used.

It is not necessary to provide a pair of temporary fasteners 10 on the auxiliary ropes. Each temporary fastener 10 is provided at the tip of one auxiliary rope, the other side is separated from the main rope 3 and the one side is inserted. It can be tight.

Incidentally, the temporary fixing member 10 is not limited to the E type, but may be an S type.

In the embodiment of the temporary fixing member 101 shown in FIG. 4, a plate 13 having two S-shaped holes is provided with a holder 15 which can be opened and closed by screws 14 and a middle part of the plate 13 is connected to a rope retainer 16 and a lower end. Type rope retainer 17
The rope 3 inserted between the pair of holes is pressed by the rope holders 16 and 17 to prevent unexpected slippage.

The embodiment of the temporary fixing member 102 shown in FIG. 5 is the ultimate temporary fixing member of the above-described embodiment, and has a semicircular lock holder 16 'for the plate 13 having two holes. The operation and effect achieved are substantially the same as those of the above-described embodiment.

The embodiment shown in FIG. 6 is an embodiment of a compact and simple temporary fixing member 18, which can stop the main rope 3 at the front end of the central projection 20 of the base plate 19 which is substantially E-shaped in plan view. As shown in FIG. 7, the main rope 3 is inserted through slits before and after the lock fitting 20 so that the lock fitting 20 is bent in a semicircular shape as shown in FIG.
It is possible to operate very easily by tightening at, and to make safe work smooth,
Moreover, it can be manufactured at low cost.

It should be noted that the safety belt of the invention of this application is not limited to the work on the front side of the free frame or the like of the slope formed on the side of the highway, but the climbing work on the slope of another mountainous area. Of course, it can also be used for rescue work and the like.

[0027]

As described above, according to the invention of this application, when performing various construction works, such as removal of a free frame or weeding on a slope formed on a side surface of an expressway, one main rope is raised and lowered. The zigzag-like work of performing the construction work on the adjacent main ropes using dog running and ascending and descending by using dog running is omitted, and the pair of adjacent main ropes is extremely An excellent effect is achieved in that the saddle can be changed smoothly and safely, and various types of construction can be carried out at the same level on the slope and facing forward.

Therefore, an excellent effect that safety is high, work efficiency is good, time is short, and highly reliable work as designed can be performed.

In addition, the safety belt is handled by inserting the main rope into the temporary fixing metal fitting and closing the lock metal fitting with one hand in a one-touch manner. An excellent effect is achieved in that the disengagement during the saddle change can be performed efficiently and smoothly and safely.

Further, there is an advantage that the main rope can be pulled out of the main rope without being reduced in diameter, and the mounted state can be temporarily maintained by frictional resistance.

There is also an advantage that the main rope cannot be removed by the lock fitting after the main rope has been attached to the temporary fixing fitting, and that the main rope cannot be removed unless the worker intentionally loosens the temporary fixing fitting.

Thus, without any skill,
Since the safety of the worker is easily and easily changed to the adjacent main rope with high safety and high efficiency, the forward construction efficiency to the slope can be extremely improved.

Also, once the main rope is entangled, a metal fitting for closing the opened hole can be covered to prevent the rope from coming off.

Another advantage is that the cost is not so different from that of the conventional safety belt and the cost is not high.
