[Industrial applications]

 TECHNICAL FIELD The present invention relates to a coaxial cable support metal fitting used for supporting a coaxial cable connected to a micro line or various communication and broadcasting antennas on a structure such as a steel tower.

[0002]

[Prior art]

 When arranging and supporting a coaxial cable along the outer surface of a structure such as an antenna tower, conventionally, fixing fittings are arranged at relatively short, predetermined intervals to withstand wind pressure vibrations. A long coaxial cable was firmly fixed to the structure (specifically, the cross rail provided on the structure). The fixing metal fittings consisted of a pair of Ω type metal fittings that sandwich the coaxial cable, and the Ω type metal fittings were connected and fixed to the structure with bolts and nuts to fix the coaxial cable to the structure.

However, if such a fixture is used, a sufficient gripping force can be obtained in order to support the load of the coaxial cable, but a fixing tool is required at all the cable supporting points, so that a mounting cost is required. However, there were many inconveniences such as many tightening operation points when assembling, which was troublesome.

Therefore, conventionally, as shown in FIG. 3, only the coaxial cable portion corresponding to the cable weight supporting point is fixed to the structure 100 by the fixing metal fitting 50, and the other steady rest supporting points are provided in the structure. There is one in which the structure 100 is supported by a simple support metal fitting 60. The tip end portion of the support fitting 60 is formed in a hook shape, and the coaxial cable 70 is hooked and supported by the hook end portion 61. With such a structure, the fixing structure of the coaxial cable 70 can be simplified without causing wind pressure vibration fatigue.

[0005]

However, in the support fitting 60 of the coaxial cable 70 thus configured, the support fitting 60 only hooks the coaxial cable 70 at the hook-shaped tip portion 61 thereof. There is a problem in that the coaxial cable 70 loosens in the support fitting 60 due to variations in the diameter of the coaxial cable 70, etc., and the steady stop cannot be achieved.

There is also a problem that workability is poor. This is because the support fitting 60 is formed by bending so that the gap formed between the tip of the fitting 60 and the structure 100 when attached to the structure 100 is smaller than the diameter of the coaxial cable 70. . This is to prevent the supported coaxial cable 70 from being detached. Therefore, the coaxial cable 70 cannot be pulled into the support fitting 60 after the support fitting 60 is attached to the structure 100, which is a limitation on the mounting work and deteriorates workability.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a coaxial cable support metal fitting that can reliably support a coaxial cable and improve installation work. .

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is a coaxial cable support fitting for supporting a coaxial cable along an outer surface of a structure, the fixing member being arranged and fixed on the outer surface of the structure, and the fixing member. It has a hook-shaped member that is integrally attached to the member and locks the peripheral surface of the coaxial cable, and a fastening string insertion hole is formed at each end of the hook-shaped member. A support bracket for coaxial cable was constructed.

The hook-shaped member is preferably attached to the fixing member with an inclination in a direction opposite to the bending direction.

[0010]

[Action]

 According to the above configuration, since the fastening string insertion holes are provided at both ends of the hook-shaped member, the fastening string is placed along the outer peripheral surface of the hook-shaped member on which the coaxial cable is hooked, and then the fastening string is inserted into the fastening string insertion hole. The coaxial cable can be firmly fixed and supported by the hook-shaped member by inserting it into the hook and fastening them together.

Further, when the hook-shaped member is attached to the fixing member while tilting in a direction opposite to the bending direction, the opening formed between the tip end portion and the base end portion of the hook-shaped member can be greatly opened. become. Therefore, the coaxial cable can be pulled into the hook-shaped member even after the support fitting is attached to the structure. It is possible that the coaxial cable may come off the support fitting due to the open opening of the hook-shaped member.However, the coaxial cable can be firmly fixed to the support fitting with a tie string, so the coaxial cable is supported. It does not come off from the metal fittings.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is a perspective view showing a state in which a coaxial cable is supported and fixed to a structure by using a coaxial cable support fitting of one embodiment of the present invention.

The coaxial cable support fitting 1 includes a fixing member 2 and a hook-shaped member 3. The fixing member 2 is made of a metal plate that is bent and formed in a "U" shape, and bolt insertion holes 4 and 4 are formed at both ends so as to face each other. The fixing member 2 is longer than the width of the horizontal rail 101 of the structure 100 (for example, an antenna tower) to which the fixing member 2 is attached. The gap formed in the fixing member 2 is formed to be slightly larger than the thickness of the horizontal rail 101.

The hook-shaped member 3 is made of a metal plate bent in a “2” shape. A base end portion 3a of the hook-shaped member 3 has a flat plate shape and serves as a mounting portion to the fixing member 2. The tip portion 3b of the hook-shaped member 3 is bent and formed at an angle of about 220 degrees in the circumferential direction so that the coaxial cable 70 can be held along the peripheral surface of the supporting coaxial cable 70. A rubber band 5 for a cushion is attached to the inner peripheral surface of the hook-shaped member 3. Then, the tip end portion 3b is connected to the base end portion 3a in a state in which the tip end portion 3b is inclined by approximately 30 degrees in the direction opposite to the bending direction. This inclination is one of the features of this embodiment. The hook-shaped member 3 thus configured is fixed to the fixing member 2. At this time, the hook-shaped member 3 is attached to the fixing member 2 so that the axial center direction of the coaxial cable 70 to be gripped is aligned with the circumferential center direction of the hook-shaped member 3. The hook-shaped member 3 is fixed by, for example, welding the base end portion 3a to the fixing member 2. By being fixed in this way, the tip portion 3b of the hook-shaped member 3 is attached to the fixing member 2 as well, inclining in a direction opposite to the bending direction thereof by approximately 30 degrees.

Further, at both ends of the hook-shaped member 3, that is, at the tip end side of the tip end portion 3b and the base end portion 3a side of the tip end portion 3b, there are fastening string insertion holes 6 and 6, which are another feature of the present embodiment. Has been formed. The fastening string insertion hole 6 on the base end portion 3a side is formed at the bending start point of the tip end portion 3b. The reason for forming the fastening string insertion hole 6 on the base end 3a side is as follows. That is, if the fastening string insertion hole 6 is formed on the tip side from the bending start point of the tip portion 3b, it becomes difficult to insert the fastening string 10 into the fastening string insertion hole 6 after the coaxial cable 70 is supported and fixed. Further, when the fastening string insertion hole 6 is formed on the proximal end portion 3a side from the bending start point, the fastening string 10 is lifted from the coaxial cable 70 and cannot be securely fastened.

An insertion guide portion 7 for the coaxial cable is provided at the tip of the hook-shaped member 3. The insertion guide portion 7 is formed by bending the front end side outward from the front end side tightening cord insertion hole 6, and by providing such an insertion guide portion 7, the coaxial cable 70 can be easily pulled in. .

Next, the supporting and fixing of the coaxial cable 70 to the structure 100 using the coaxial cable support metal fitting 1 having the above-described configuration will be described.

First, the open end of the fixing member 2 is inserted from the upper end of the horizontal rail 101 of the structure 100, the bolt 8 is inserted into the bolt insertion hole 4, and the nut 9 is tightened. By this, the coaxial cable support fitting 1 is fixed to the horizontal rail 101. In this way, since the horizontal rail 101 is sandwiched between the bolt nut and the fixing metal fitting 2, the coaxial cable support metal fitting 1 does not come off from the horizontal rail 101. After being fixed to the horizontal rail 101, the coaxial cable 70 is pulled into the hook-shaped member 3 from the opening 11 formed between the front end of the hook-shaped member 3 and the base end 3a. At this time, the tip portion 3b of the hook-shaped member 3 is attached to the fixed member 2 inclining in a direction opposite to the bending direction, and the opening 11 is wide open. Therefore, even after the coaxial cable support fitting 1 is attached to the horizontal rail 101, the coaxial cable 70 can be easily pulled in.

After the coaxial cable 70 is drawn into the coaxial cable support fitting 1, the coaxial cable support fitting 1 and the coaxial cable 70 are integrally fastened with the fastening string 10. As the fastening string 10, a nylon fastening band called tie wrap, which is generally used for binding electric wires, is preferable. The fastening cord 10 is inserted into both the fastening cord insertion holes 6 and 6, and the both ends of the hook-shaped member 3 are connected together along the outer peripheral surface of the hook-shaped member 3, whereby the coaxial cable 70 is attached to the coaxial cable support fitting 1. To conclude. In this way, since the coaxial cable 70 is fixed to the coaxial cable support metal fitting 1 by the fastening string 10, the coaxial cable 70 does not float in the coaxial cable support metal fitting 1 and further, the coaxial cable support metal fitting 1 does not move. Even though the opening 11 is wide open, the coaxial cable 70 does not come off from the coaxial cable support fitting 1.

The coaxial cable support fitting 1 of the present embodiment is a fitting attached to the steady rest support point of the coaxial cable 70, and such a weight support point of the coaxial cable 70 is the fixing fitting 50 described in the conventional example. Needless to say, it is fixed to the structure 100.

Further, in the above embodiment, the fixing member 2 and the hook-shaped member 3 which are separately formed are welded to each other to form the coaxial cable support fitting, but the invention is not limited to this, and the fixing member 2 and the hook are not limited thereto. The metal fitting 3 may be integrally molded to form a coaxial cable support fitting.

In addition, although one hook member 3 is attached to the fixing member 2 in the above embodiment, the present invention is not limited to this, and hook members 3 and 3 can be attached to both sides of the fixing member 2. You may comprise a coaxial cable support metal fitting. Then, the coaxial cable 70 can be efficiently supported with a small occupied area.

[0023]

[Effect of device]

 As described above, according to the present invention, since the fastening string insertion holes are provided at both ends of the hook-shaped member, after the fastening string is laid along the outer peripheral surface of the hook-shaped member into which the coaxial cable is drawn, the fastening string is formed. It is now possible to firmly fix and support the coaxial cable by inserting the cable into the fastening string insertion hole and fastening them together. Therefore, the inconvenience that the coaxial cable fluctuates in the coaxial cable supporting bracket and the steady rest cannot be prevented is prevented.

Further, when the hook-shaped member is attached to the fixing member by inclining it in the direction opposite to the bending direction of its tip, the opening formed between the tip and the base end of the hook-shaped member is formed. It will be wide open. Therefore, the coaxial cable can be pulled into the hook-shaped member even after the support metal fittings are attached to the structure, which improves the workability of the coaxial cable attachment. It should be noted that although the coaxial cable can be easily removed due to the wide opening of the opening, it cannot be removed because the coaxial cable is firmly fastened to the support fitting with the fastening string.
