Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a scaffolding fitting attached to the side of a utility pole for raising and lowering the utility pole.

(Prior Art) Concrete or wooden utility poles for installing electric wires, telephone lines, etc. are attached with scaffolding fittings for lifting and lowering for construction purposes.

FIG. 3 shows an example of a conventional scaffolding fitting. Reference numeral 1 denotes a round rod body made of steel, with a threaded portion 2 threaded on one side and a hexagonal or trapezoidal head 3 on the other side. Furthermore, a recess 4 is carved on the surface of the round rod 1 to prevent slippage.

In FIG. 4, to explain the state in which the above-mentioned scaffolding metal fittings are installed together, the screw hole 6 provided on the side of the utility pole 5 has a
The screw portions 2 are screwed together, and the head 3 is tightened using a spanner or the like to fix it. Workers carefully move up and down the scaffolding fittings with each step, and sometimes use them as scaffolding during work.

(Problems that the invention aims to solve) The above-mentioned conventional scaffolding fittings for raising and lowering utility poles are made of round steel rods, so they are thin and slippery as stepping stones, and the recesses on the surface are deeply carved. Therefore, the slip prevention effect is not sufficiently achieved. In addition, when working at dusk or at night, it was difficult to see and there was a risk of tripping.

In most cases, they are installed on utility poles outdoors, so they are susceptible to rust due to rain, etc., and are not aesthetically pleasing. Particularly in scenic spots, the trees are sometimes painted to match the color of the surrounding area so as not to spoil the beauty.

The purpose of the present invention is to provide scaffolding metal fittings with improved safety and aesthetic appearance.

(Means for solving the problems) The present invention, as a means for solving the above problems,
In a scaffolding fitting for lifting that has a fastening part to the side of a utility pole, and a grip part and a footrest connected to the fastening part, the gripping part and the footrest are covered with plastic and have a rectangular cross section. A plurality of concave portions approximating the thickness of fingers are provided in parallel on both sides of the grip portion where the fingers sometimes hang, and a plurality of convex portions are provided in parallel on both the upper and lower surfaces of the foothold portion, and both ends of the both sides are provided with a plurality of concave portions in parallel. The structure includes a prism-type reflector.

(Function) The present invention has the above-mentioned configuration, so that when going up and down,
It is possible to provide scaffolding metal fittings that are easy to grip and prevent the feet from slipping, and can be made in various colors by changing the color of the plastic.

In addition, prism-type reflectors are attached to both the upper and lower ends of the footrest, making it possible to sharply catch and reflect faint light even when working at dusk or at night.

(Example) An example of the present invention is shown in the plan view of Fig. 1 and the plan view of Fig. 2.
This will be explained using a side view of the figure.

This scaffolding metal fitting 10 uses a steel core material 11,
A threaded portion 12 is provided at one end and is screwed into a screw hole 14 provided in a utility pole 13 for fixation. The other parts are covered with plastic and have a rectangular cross section. This covered part has a grip part 1
5 and a foothold part 16, a plurality of recesses 17 approximately the thickness of a finger are arranged in parallel on the side grip part 15, and an X-shaped convex part 18 is provided on the top and bottom foothold parts 16. are installed in parallel. Here, the X-shaped convex portion 18
The reason why they are provided on the upper and lower surfaces is that it can be installed with either side facing up. Further, a flange 19 is provided on the outside to prevent side slipping.

20 is a circular prism type reflector, which uses special materials such as hard plastic.
It has excellent impact resistance and is scratch resistant.
It is attached at four locations on both upper and lower surface edges of the footrest portion 16.

(Effects of the invention) Since the invention has the above-described configuration, it has the following effects.

When gripping the grip part with your hand to move up and down the telephone pole, each finger fits into each recess for easy gripping, and the square cross section prevents it from slipping in your hand.
In addition, there is a highly protruding convex non-slip part on the part where the feet are placed, so you can use your hands and feet effectively to ascend and descend with a sense of security, increasing safety.

Since the exposed parts of the utility poles are covered with plastic, they will not rust and will not be damaged by rust. Also, at scenic spots, plastics with colors that match the surroundings can be used without compromising the aesthetics.

Covering with plastic in a highly visible color such as yellow can make it easier to see when working at dusk or at night. Furthermore, as shown in the example, by attaching a prism-type reflector that sufficiently reflects even weak light to a part of the footrest, it clearly guides the position where the foot is placed and the direction in which it goes up and down, making it safer and more It can be moved up and down reliably.

Even if a wire breaks and becomes entangled in a part of the scaffolding fittings and is used unknowingly, the exposed part is made of non-conducting plastic, which prevents electric shock accidents.

Birds tend to perch on scaffolding metal fittings, dropping droppings on passersby, and accidents such as slipping due to droppings when going up and down utility poles can occur. As a countermeasure against this problem, by providing two circular prism-type reflectors as shown in the embodiment, it is possible to prevent birds from congregating under the illusion that they are human eyes.
