Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety rope holder for aerial work for binding or passing a safety rope for connecting a lifeline when working at a high place such as a construction site.

[0002]

2. Description of the Related Art When working at a high place such as a construction site, a lifeline is attached to prevent a worker from falling. One end of the lifeline is connected to the belt worn by the worker,
The other end is connected to a safety rope. The safety rope is tied and tied around the pillars that make up the building. Since a locking tool is provided at the other end of the life rope and the locking tool is connected through the safety rope, the worker can move with the life rope attached within the range where the safety rope is stretched.

[0003]

However, since the safety rope is bound to a steel frame or the like, there are cases where there is no appropriate member such as the steel frame at the place where the safety rope is desired to be stretched. Further, when the safety rope is stretched over a long distance, the midway portion of the safety rope may be slackened to hinder the work, or the worker may fall and cause a danger when the worker falls.

The present invention has been made by paying attention to the above-mentioned conventional problems, and it is possible to freely stretch the safety rope even at a place where there is no member for binding the safety rope such as a pillar at a construction site of a building. Moreover, it is an object of the present invention to provide a safety rope holder for work in high places, which can prevent the safety rope from slackening, and a method for manufacturing the same.

[0005]

According to a first aspect of the present invention, there is provided a holder main body, a fitting portion which is formed at a lower end portion of the holder main body and which is fitted to a fixed member such as a steel frame, and the fitting portion in the previous term. Safety rope for aerial work, which includes a fixing bolt whose front end is brought into pressure contact with a fixed member such as a steel frame by being tightened, and a rope holding portion which is provided in the holder main body to bind or pass the safety rope. It is a holder.

According to a second aspect of the present invention, there is provided a holder main body, a fitting portion which is formed at a lower end portion of the holder main body and which is fitted to a fixed member such as a steel frame, and which is provided in the fitting portion and is tightened. A safety rope holder for aerial work, which comprises a fixing bolt whose tip is pressed against a fixed member such as a steel frame, and a rope holder provided on the holder body for binding or passing a rope, is made of aluminum. A method for manufacturing a safety rope holder for work in high places, which is characterized by being partially manufactured by forging.

[0007]

According to the invention of claim 1, the fitting portion formed at the lower end portion of the holder main body is fitted to a steel frame or the like, and the fixing bolt is tightened so that the tip end of the fixing bolt is pressed against the steel frame or the like to hold it. Fix the ingredients. Then, the safety rope is bound or passed through the rope holding portion, and the life rope is connected to the safety rope.

In the invention of claim 2, since the safety rope holder is made of aluminum, the weight can be reduced. Further, since it is manufactured by forging, the structure becomes dense, the strength is high, and there is almost no difference in strength between the parts.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A safety rope holder 1 for working in high places according to an embodiment of the present invention will be described with reference to the drawings. The safety rope holder 1 for working at high places is made of aluminum. Reference numeral 3 indicates a holder main body, and a square-shaped rope holding portion 5 is fixedly provided on the upper end of the holder main body 3. Further, a handle 7 is fixed to an intermediate part of the holder main body 3.

At the lower end of the holder body, projecting portions 11 and 13 are arranged at intervals in the vertical direction, and the fitting portions 9 are formed by the projecting portions 11 and 13. A pair of screw holes 14 are formed in the protruding portion 11, and fixing bolts 15 are inserted into the screw holes 14. A pressing member 17 is provided at the lower end of the fixing bolt 15.

Next, this safety rope holder 1 for work at high places
The manufacturing method of will be described. The fitting portion 9 is manufactured by forging, and the pressure applied to the fitting portion 9 at this time is several tons to several hundreds of tons. Thus, when the fitting portion is manufactured by forging, the structure becomes dense and has a large strength. If the structure is made by casting, the structure becomes coarse and the strength becomes small, and the density of the structure may be uneven, and there is a possibility that a portion that is easily damaged is formed.

Further, if the safety rope holder 1 is manufactured by forging, the number of welded parts is reduced as compared with the case where it is manufactured by casting, and the number of steps and the time required for manufacturing can be reduced. Furthermore, since the number of welded portions can be reduced, it is possible to reduce the number of welded and easily peeled portions.
The fitting portion 9 manufactured by forging is fixed to the holder main body 3 by welding. Further, the rope holding portion 5 is attached by welding the portion indicated by the one-dot chain line a in FIG. 1, and the handle 7 is also attached by welding.

Next, a method of using the safety rope holder 1 for working in high places will be described. The safety rope holder 1 is used by being fixed to the steel frames 19 constituting the building at predetermined intervals. That is, the fitting portion 9 is attached to the steel frame 19 with the fixing bolt 15 loosened.
To fit. Then, the fixing bolt 15 is tightened, and the steel frame 19 is sandwiched by the protruding portion 13 and the pressing member 17 of the fixing bolt 15 to fix the safety rope holder 1 to the steel frame 19.

Then, the safety rope 21 is passed through the rope holding portion 5 of the safety rope holder 1, and the both ends of the safety rope 21 are bound to a fixed member such as a pillar (not shown). Worker 23
One end of the lifeline 27 is connected to the belt 25 of the
A locking tool 29 is attached to the other end of the. The locking tool 29 is connected to the safety rope 21, and the lifeline 27 is attached to the safety rope 21. Since the safety rope 21 is loosely passed through the lock 29, the worker 23 can move freely while the safety rope holder 1 is arranged.

As described above, when the safety rope 21 is passed through the rope holding portion 5 of the safety rope holder 1 for working at a high place, the intermediate portion is supported, so that the loosening can be prevented. Therefore, the safety rope 21 is kept taut, and even if the worker 23 falls from the steel frame 19, it is possible to prevent the worker 23 from swinging, and the worker 23 is injured. Can be prevented.

Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment, and the present invention is applicable even if there is a design change or the like without departing from the scope of the present invention. Included in the invention. The safety rope holder 1 for working in high places may be used by binding the safety rope 21 through the rope holding portion 5 as described above, or by binding it to the rope holding portion 5. If you do this, the safety rope 2
The safety rope can be stretched even in a place where there are no pillars for binding 1.

In addition to the steel frame 19, the safety rope holder 1 may be fixed to a square pipe or the like which constitutes a scaffold for building construction. A safety rope holder for work in high places 1
Not only the fitting portion 9 of the above, but other portions may be manufactured by forging.

[0018]

As described above, according to the present invention, it is possible to freely stretch the safety rope even at a place where there is no member for binding the safety rope such as a pillar in a construction site of a building. Further, even when the safety rope is stretched over a long distance, it becomes possible to prevent the safety rope from slackening.
