〔考案の背景と目的〕
本考案は電力ケーブル及び防災パイプの両者を
固定支持し得るクリートに関するものである。[Detailed Description of the Invention] [Background and Purpose of the Invention] The present invention relates to a cleat that can securely support both power cables and disaster prevention pipes.
従来電力ケーブルに例えば防災用のパイプを用

だけであつた。このため電力ケーブルは各種の振
動により容易に振動してしまい電力ケーブルに大
きな応力が働き、金属シース部分が疲労するとい
つた欠点を有していた。 Conventionally, when a disaster prevention pipe is used as a power cable, only the pipe inserted into the necessary disaster prevention part of the power cable is fixedly supported, and the power cable is simply inserted directly into the pipe. Ta. Therefore, the power cable easily vibrates due to various vibrations, which causes large stress to act on the power cable, resulting in fatigue of the metal sheath.
本考案の目的は前記した従来技術の欠点を解消

可能としたによりケーブル及び防災用の如きパイ
プを一括締付け固定することにある。 That is, the feature of the present invention is that a pair of semi-cylindrical members having through-holes for attaching bolts on their outer peripheries have a curved inner circumferential surface that can be gripped with the cable passing through the central part of the pair, and the semi-cylindrical At least one end of the member has a radius of curvature larger than the curved inner circumferential surface of the central portion to form a curved inner circumferential surface that can hold the end of the pipe into which the cable is inserted in a fitted state. By tightening the bolts of the pair of semi-cylindrical members, the pipes and cables can be tightened and fixed all at once, thereby making it possible to tighten and fix the cables and the pipes, such as those for disaster prevention, at once.

挿通して行なう。 In Fig. 1, the cleat is composed of a pair of semi-cylindrical members 1 and 2, each of which has a through-hole 3 for attaching a bolt that integrates the two semi-cylindrical members. . Further, the curved inner circumferential surfaces of each semi-cylindrical member are stepped, and the radius of curvature of the end curved inner circumferential surface 5 is larger than that of the curved inner circumferential surface 4 of the central portion. Therefore, when a pair of semi-cylindrical members are put together, the power cable 13 is gripped by the penetrating state of the power cable 13 shown by the dashed line as shown in FIG. The ends of the pipe 12 are held in a fitted state by the curved inner circumferential surfaces 5, 5 of the ends. Incidentally, these tightening operations are performed by inserting bolts (not shown) into the bolt attachment through holes 3.
尚、本実施例では防災用パイプ取付け固定用の
端部内周面５を第１図に示すように両端部に設け
たが、必らずしもこの限りではなく、必要に応じ
片側のみにしても良いことはいうまでもない。 In this embodiment, the inner circumferential surface 5 of the end portion for attaching and fixing the disaster prevention pipe is provided at both ends as shown in FIG. Needless to say, it's a good thing.
又、クリートに適用できる材質はアルミ合金、
補強剤入りFRPなどが強度、コスト、重量、作
業性などの面から考えて好ましい。しかし必らず
しも材質を上記に限定するものではない。 In addition, the materials that can be used for cleats are aluminum alloy,
FRP containing reinforcing agent is preferable in terms of strength, cost, weight, workability, etc. However, the material is not necessarily limited to the above.

を行なう。 Figure 3 shows the power cable installation row using the present invention, in which the joint box main body 7 is fixed with a joint box fixing cleat 8, and the power cable 13 near the leadwork section 9 is fixed to the power cable. Fix with cleat 10. Reference numeral 11 denotes a cleat according to the present invention, and this cleat 11 is used to bolt together the end of the disaster prevention pipe 12 and the power cable 13 protruding from the end of the pipe.

1 are mounted on a support stand 14, and external vibrations are transmitted to the joint box 7 and the power cable 13 via the support stand 14. Furthermore, the power cable 13 is placed within the disaster prevention pipe 12 without touching it, and is susceptible to vibration. By fixing the power cable with the cable fixing cleat 10, the degree of freedom of the cable against vibration is reduced, and by further fixing the power cable 13 and the disaster prevention pipe 12 with the cleat 11, vibration can be further suppressed.

As detailed above, in the present invention, the cleat itself has a simple structure, and since the power cable and the pipe for disaster prevention are fixedly supported together, external vibrations can damage the metal sheath of the power cable. This makes it possible to prevent fatigue and improve the reliability of the cable.
