Description

[Detailed description of the invention] This invention does not use steel wire, but instead uses a thin metal strip made of thin stainless steel plate, one end of which is directly wrapped around the suspension line, and the other end of which holds the cable. This invention relates to a cable hanger for hanging general cables.

Japanese Patent Application Laid-open No. 54-96796 related to the invention of the inventor of the present invention
In order to safely support cables with large diameters and large loads, the cable hanger is made of a metal plate band or electrically insulating cloth, with a highly elastic steel wire attached to the suspension line and holding the cable on the steel wire. It supports the band. Therefore, it is necessary to manufacture the band and the steel wire separately, and in order to hang the cable by passing the steel wire through the hole drilled in the band, the band moves back and forth, left, right, up and down due to wind pressure, etc. If the periphery of the hole in the body is cut to increase the diameter of the hole and weaken the strength of the band, the part that holds the cable and the band may move and damage the outer circumferential surface of the cable. When performing striding work, a steel wire must be passed through a hole in the cable after the band is wrapped around the cable, and the steel wire must be hooked to a suspension line, which has the disadvantage of poor work efficiency.

In addition, a patent application filed in 1983 related to the invention of the creator of this invention
In No. 64574, one tongue piece is provided at one end of the hanging piece, the middle part of this hanging piece is hung above the hanging wire, the tongue piece is passed under the hanging wire, and the tip of the tongue piece is hooked. The hook piece is inserted into a hole drilled at the other end of the piece, and the tip thereof is bent onto the outer surface of the hook piece that is hung on the hanging line, thereby fixing the hook piece to the hanging line. However, it is necessary to increase the strength of the cable hanger especially when the type of cable changes or when the cable hanger is used in areas with particularly high wind pressure or snow cover. At the same time, in order to increase the strength of the hooking piece, its thickness must be increased or its width must be increased. Increasing the thickness of the hooking piece has the drawback of making it difficult to handle it.

In the present invention, one tongue piece and the other tongue piece are provided facing each other on the hanging piece of the hanging line, and these tongue pieces protrude inwardly on both sides of the hanging piece that is hung on the hanging line. By crushing and deforming the tongue piece with pliers, etc., and firmly sandwiching and fixing the hanging wire between the middle part of the relatively thin hook piece, one tongue piece, and the other tongue piece, without using the conventional steel wire part, By using a thin metal strip such as a thin stainless steel plate for the band, one end of which is wrapped directly around the suspension line and fixed, and the other end is used to hold the cable, the break strength of the hanger is increased, making it different from conventional cable hangers. The purpose is to have several times the strength of the steel, to facilitate the construction work, and to be able to provide it at a low cost.

The configuration, operation, and effects of the present invention will be explained with reference to drawings of embodiments.

Figure 1 A, B, C, and D show one hooking piece A to the suspension wire. Figure 1A is a developed view, in which one U-shaped incision 10 is opened at one end and one tongue piece 1 is opened.
form 1. Further, the other tongue piece 13 is formed symmetrically with the one tongue piece 11 by opening the other cut window 12 at the other end. Enlarged cut windows 14, 14 are formed on both sides of the center of the other cut window 12 in order to insert the neck portion 20 of the other hooking piece B shown in FIG. In Figure 1 B, C, and D, one hooking piece A is bent with a radius approximately equal to the radius of the suspension wire around the line X ₁ - X ₁ in Figure 1 A, and one tongue piece 11 and the other tongue piece Fold piece 13 to line 11
After bending inward from a and 13a, the areas of one cut window 10 and the other cut window 12 are expanded, so they are used for inserting the tips of pliers.

Further, the other end edge 15 of one hooking piece A is bent inward from the folding line X ₂ -X ₂ into a claw shape.

FIG. 2 shows the other hooking piece B to the hanging wire. The other hook piece B has a cut window 21 through which one end of the band C is inserted.
and a neck portion 20 that is inserted through the cut windows 14, 14 of one hooking piece A.

In Fig. 3 A, B, and C, C and C' indicate hanger bands made of SUS304 stainless steel strip, etc.

This figure shows a case in which a cable hanger is suspended by parent and child, that is, two cables are hung.Of course, if a single cable is hung, only one band is used.
D and D' are electrically insulating resin covers made of vinyl chloride resin or the like, and have a square-shaped groove 40 in cross section, and the middle part of the band C is inserted and covered inside this square-shaped groove. As shown in Fig. 3 A and B, insert the middle part of the band C into the cutout 10 of one of the hook pieces A with the electrically insulating resin covers D and D' fitted in the middle part, making a difference in length and shortness. Fix the terminal part by welding. Insert the end of one band C through the cut window 21 of the other hooking piece B, bend it, and fix the end by spot welding, and fix the end of the other band C', which is longer than the other band C. Cut window 2 of the other hook piece B'
1' and fix the end part by spot welding.

4A, 4B, 4C and 4D are explanatory views of the order in which the cable hanger of the present invention is attached to the suspension line E and the upper cable F and lower cable F' are suspended from the suspension line E. First, hook the hooking piece A onto the hanging wire E (Fig. 4A). Then, pull both sides of the hook A toward the inside in a U-shape by squeezing with fingertips or pliers from both outside sides in the direction of the arrow. When both sides of the hook A are pulled inward, one of the two tongue pieces 11 protrudes inward.
and the other tongue piece 13 are strongly pressed against the suspension wire E. Next, insert the tip of the pliers G into the other incision window 12 located directly below the other tongue piece 13, and
Grip the tip firmly and press it against the suspension wire E to fix it. Similarly, attach the tip of pliers G to one of the cutting windows 10.
, firmly squeeze the tip of one tongue piece 11, and press the other tongue piece 13 onto the hanging wire E from above to fix it. Next, the cable F is placed on one of the bands C, and as shown in FIG.
It is inserted through the enlarged cut windows 14, 14, and then dropped toward the hook-shaped edge 15 and locked. Next, place the lower cable F' on the other band C' and hold it in place, and as shown in FIG. It is inserted through the enlarged slits 14, 14 of the slit 12, dropped onto the hook-shaped edge 15, overlapped, and locked. The cables F and F' are both held by the bands C and C' via electrically insulating resin covers D and D' which cover the intermediate portions of the bands C and C'.

Figure 5 shows how three cables are connected to bands C, C', and
It shows the state in which each band is placed and held on C''.The length of each band is long or short, and the method of assembly is the same as that described for Fig. 4 A, B, C, and D above.

As mentioned above, the present invention does not use a steel wire, but instead uses a metal thin strip with two tongue pieces and two cut windows arranged side by side at one end of a strip made of a thin metal strip. By providing a hook piece and providing the other hook piece with a neck at the other end of the band, the middle part of one hook piece is hung on the suspension line and bent into a U-shape, and each of the one hook piece is By inserting your finger or the tip of pliers through the cut window, you can tightly wrap and crimp each tongue piece around the suspension wire from both sides of the suspension wire. The cable can be suspended from the overhead wire by simply inserting the neck of the other hook piece provided at the other end of the band into the other cut window of the one hook piece and hooking the cable. Even if the cable swings due to wind pressure or vibration, the connection between the suspension line and the band will not come loose, and the cable suspension work will be extremely easy.
