[0002] When laying electric wires in structures such as the accommodation and engine room of a ship, the wires are often laid along the ceiling or wall. For example, as described in Patent Document 1, an electric wire installation conduit is used that includes main girders (hereinafter referred to as "runner bars") arranged parallel to each other, sub girders (hereinafter referred to as "hangers") installed perpendicular to the runner bars at regular intervals, and support members for attaching ladder members made up of the runner bars and hangers to the structure. Generally, electric wires are laid on the hangers and secured with fixing members such as bands. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-143729 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when the support members and runner bars are fastened with bolts and nuts, there is a possibility that the bolts may loosen due to vibrations transmitted from the structure, so spring washers are required.In particular, since ships have a large number of support members, using spring washers increases the number of parts and the labor required.

[0005] The present invention has been made in view of the above problems, and has as its object to provide a cable laying cable line and a ship that can reduce the number of parts and the number of work steps. [Means for solving the problem]

[0006] According to the present invention, there is provided an electrical conduit for laying electric wires, which comprises at least a pair of support members arranged on the surface of a structure on which electric wires are laid, a support metal fitting for supporting the electric wires, and a bolt fastening portion for connecting the support metal fitting to the support member, and which is characterized in that it comprises a pair of legs that form a predetermined space between the support metal fitting and the support member at the bolt fastening portion.

[0007] The support hardware may comprise a pair of runner bars arranged along the laying direction of the electric wire, and a plurality of hangers arranged perpendicular to the pair of runner bars, and the legs may be formed on the runner bars.

[0008] The leg portion may be formed from a channel steel, a C-shaped steel, or a special shaped steel in which the tip of a bent portion of a channel steel that constitutes the runner bar is rounded.

[0009] The runner bar may be arranged such that the open side of the groove faces the support member, and the hanger is connected to the bottom of the groove.

[0010] The bolt fastening portion may be a structure that fastens the support member and the runner bar together, or may be a structure that fastens the support member, the runner bar, and the hanger together.

[0011] The hanger may include a support portion that supports the electric wire and a bent portion that is connected to the runner bar. In this case, the hanger may be disposed so as to be convex toward the surface side of the structure.

[0012] The support metal may include a support portion for supporting the electric wire and a bent portion formed at both ends of the support portion, and the leg portion may be formed at the bent portion. In this case, the support metal may be arranged so as to be convex toward the surface side of the structure.

[0013] The legs may be formed on the support member. Furthermore, according to the present invention, there is provided a ship comprising an electric cable laying cable line including any one of the above-described configurations. [Effects of the Invention]

[0014] According to the electric cable laying cable and ship of the present invention, a pair of legs are provided to form a predetermined space between the support metal fitting and the support member at the bolt fastening portion, so that the legs can apply a spring force to the bolt fastening portion, eliminating the need for a spring washer to prevent loosening. Therefore, according to the present invention, the number of parts and the number of work steps can be reduced. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, an embodiment of the present invention will be described with reference to Fig. 1(A) to Fig. 11(C). Here, Fig. 1 is a perspective view showing an overview of an electric cable laying circuit according to this embodiment, in which (A) shows a ladder-shaped electric cable circuit and (B) shows a single electric cable circuit.

[0017] 1(A) and 1(B), an electric cable laying circuit 1 according to one embodiment of the present invention comprises at least a pair of support members 2 arranged on the surface of a structure on which an electric cable C is laid, a support metal fitting 3 that supports the electric cable C, and a bolt fastening portion 4 that connects the support metal fitting 3 to the support member 2. For ease of explanation, in FIGS. 1(A) and 1(B), only a portion of the electric cable C arranged on the support metal fitting 3 is shown by a dotted line.

[0018] The support member 2 is a steel material fixed to the surface of a structure. The structure is, for example, the hull of a ship. In this embodiment, the support member 2 is illustrated as being placed on the ceiling of the structure, but it may also be placed on a wall or floor. Note that the structure is not limited to the hull of a ship.

[0019] The support metal fitting 3 shown in Fig. 1(A) comprises a pair of runner bars 31 arranged along the laying direction of the electric wire C, and a plurality of hangers 32 arranged perpendicular to the pair of runner bars 31. The support metal fitting 3 shown in Fig. 1(A) is formed in a ladder shape by the runner bars 31 and the hangers 32. In this specification, an electric circuit equipped with such a ladder-shaped support metal fitting 3 will be referred to as a ladder-shaped electric circuit.

[0020] The electric wire C is fastened to the hanger 32 by, for example, a band. The hanger 32 has a long hole formed therein for inserting the band. Both ends of the hanger 32 may be welded to the runner bar 31 or fastened by a bolt or the like. For the sake of convenience of explanation, the band is not shown in Figs. 1(A) and 1(B).

[0021] 1(B) includes a support portion 33 that supports the electric wire C and bent portions 34 formed on both ends of the support portion 33. The support portion 3 shown in FIG. 1(B) is used in narrow spaces, in other words, the support portion 3 is configured using only the hanger 32, omitting the runner bar 31 shown in FIG. 1(A).

[0022] The electric cable laying circuit 1 shown in Figures 1(A) and 1(B) is characterized by having a pair of legs 5 that form a predetermined space G between the support metal fitting 3 and the support member 2 at the bolt fastening portion 4. First, the case where the electric cable laying circuit 1 is the ladder-shaped electric cable laying circuit shown in Figure 1(A) will be described with reference to Figures 2(A) to 7(C).

[0023] 2A and 2B are diagrams showing the bolt fastening portion of the first embodiment, where (A) is a front view, (B) is a first modified example, and (C) is a second modified example.

[0024] In the first embodiment shown in Fig. 2(A), the bolt fastening portion 4 is formed by fastening the support member 2 and the runner bar 31 with bolts 41 and nuts 42. The runner bar 31 is formed, for example, from a channel steel that is long in the laying direction of the electric wire C, and both ends that form the channel are bent to form the leg portion 5. The runner bar 31 is arranged with the open side of the channel steel groove on the outside, and a hanger 32 is connected to the bottom of the channel steel.

[0025] The hanger 32 has, for example, a substantially U-shape with a support portion 32a that supports the electric wire C and a bent portion 32b that is connected to the runner bar 31. The hanger 32 is fixed to the runner bar 31 so that it is convex on the side opposite to the surface of the structure S (concave on the surface side of the structure S).

[0026] In this embodiment, the support hardware 3 is fixed to the support members 2 by contacting the runner bar 31 with the inside of a pair of support members 2 and fastening bolts 41 and nuts 42. At this time, the bent portions (leg portions 5) of the channel steel constituting the runner bar 31 come into contact with the support members 2, and a predetermined space is formed by the grooves of the channel steel.

[0027] In this way, by forming a space G at the bolt fastening portion 4 using the leg portion 5, a spring force can be applied to the bolt fastening portion 4, a spring washer for preventing loosening can be omitted, and the number of parts and labor required for the electric cable laying circuit 1 can be reduced.

[0028] In the first modified example shown in Fig. 2(B), the runner bar 31 is formed from a C-shaped steel (lip channel steel). Even with this configuration, a spring force can be applied to the bolt fastening portion 4 by the bent portion (leg portion 5) of the C-shaped steel.

[0029] In the second modified example shown in Fig. 2(C), the runner bar 31 is formed from special shaped steel with rounded tips at the bent portions of channel steel. Even with this configuration, a spring force can be applied to the bolt fastening portion 4 by the bent portions (leg portions 5) of the special shaped steel.

[0030] 3A and 3B are diagrams showing a bolt fastening portion of a second embodiment, where (A) is a front view, (B) is a first modified example, and (C) is a second modified example. Note that the same components as those in the first embodiment described above are given the same reference numerals and redundant explanations will be omitted.

[0031] The electric wire laying circuit 1 according to the second embodiment shown in Fig. 3(A) is configured such that the hanger 32 shown in Fig. 2(A) is fixed to the runner bar 31 so as to be convex on the surface side of the structure S. When the hanger 32 is arranged so as to be convex on the surface side of the structure S, it is possible to reduce the unevenness of the space G in which the electric wire C is laid, making it easier to lay the electric wire C.

[0032] Furthermore, when the hanger 32 is arranged convexly on the surface side of the structure S, the support surface of the electric wire C can be inclined by tilting the mounting angle of the hanger 32 relative to the runner bar 31, making it easier to guide the electric wire C at the end of the support hardware 3.

[0033] The electric cable laying circuit 1 according to the first variant of the second embodiment shown in Figure 3(B) has the hanger 32 shown in Figure 2(B) fixed to the runner bar 31 so that it is convex toward the surface side of the structure S.

[0034] The electric cable laying circuit 1 according to the second variant of the second embodiment shown in Figure 3(C) has the hanger 32 shown in Figure 2(C) fixed to the runner bar 31 so that it is convex toward the surface side of the structure S.

[0035] 4A and 4B are diagrams showing a bolt fastening portion of a third embodiment, where (A) is a front view, (B) is a first modified example, and (C) is a second modified example. Note that the same parts as those in the first embodiment described above are given the same reference numerals and redundant explanations will be omitted.

[0036] In the electric cable laying circuit 1 according to the third embodiment shown in Fig. 4(A), when the positions of the support member 2 and the hanger 32 overlap, a runner bar 31 is sandwiched between the support member 2 and the hanger 32 and bolts 41 and nuts 42 are fastened. Even with this configuration, the bent portion (leg portion 5) of the runner bar 31 can apply a spring force to the bolt fastening portion 4. The other configurations are the same as those of the first embodiment shown in Fig. 2(A).

[0037] The electric cable laying conduit 1 according to a first modified example of the third embodiment shown in Fig. 4(B) has a runner bar 31 formed from a C-shaped steel (lip channel steel). The electric cable laying conduit 1 according to a second modified example of the third embodiment shown in Fig. 4(C) has a runner bar 31 formed from a special shaped steel in which the tip of the bent part of the channel steel is rounded.

[0038] 5A and 5B are diagrams showing a bolt fastening portion of a fourth embodiment, where (A) is a front view, (B) is a first modified example, and (C) is a second modified example. Note that the same parts as those in the third embodiment described above are given the same reference numerals and redundant explanations will be omitted.

[0039] The fourth embodiment of the electric cable laying circuit 1 shown in Figure 5(A) is similar to the third embodiment shown in Figure 4(A) in that when the positions of the support member 2 and the hanger 32 overlap, a runner bar 31 is sandwiched between the support member 2 and the hanger 32 and bolts 41 and nuts 42 are fastened.

[0040] Furthermore, in the third embodiment shown in Figure 4(A), the hanger 32 is arranged so that it is convex on the side opposite to the surface of the structure S (concave toward the surface side of the structure S), but the hanger 32 may also be arranged so that it is convex toward the surface side of the structure S, as in the fourth embodiment shown in Figure 5(A).

[0041] In the fourth embodiment shown in Fig. 5(A), the runner bar 31 is formed from a channel steel. In a first modified example of the fourth embodiment shown in Fig. 5(B), the runner bar 31 is formed from a C-shaped steel, and in a second modified example of the fourth embodiment shown in Fig. 5(C), the runner bar 31 is formed from a special shaped steel in which the tip of the bent part of the channel steel is rounded.

[0042] 6A and 6B are diagrams showing a bolt fastening portion of the fifth embodiment, where (A) is a front view, (B) is a first modified example, and (C) is a second modified example. Note that the same parts as those in the third embodiment described above are given the same reference numerals and redundant explanations will be omitted.

[0043] The electric cable laying conduit 1 according to the fifth embodiment shown in Fig. 6(A) has the open side of the groove of the channel steel constituting the runner bar 31 brought into contact with the bent portion 32b of the hanger 32 and fastened with a bolt 41 and a nut 42. When the positions of the support member 2 and the hanger 32 overlap, the support hardware 3 may be configured so that the tip of the leg 5 faces the hanger 32 side, as shown in Fig. 5(A).

[0044] The electric cable laying conduit 1 according to a first modified example of the fifth embodiment shown in Fig. 6(B) has a runner bar 31 formed from a C-shaped steel (lip channel steel). The electric cable laying conduit 1 according to a second modified example of the fifth embodiment shown in Fig. 6(C) has a runner bar 31 formed from a special shaped steel in which the tip of the bent part of the channel steel is rounded.

[0045] 7A and 7B are diagrams showing a bolt fastening portion of the sixth embodiment, where (A) is a front view, (B) is a first modified example, and (C) is a second modified example. Note that the same parts as those in the fifth embodiment described above are given the same reference numerals and redundant explanations will be omitted.

[0046] In the fifth embodiment shown in Figure 6(A), the hanger 32 is arranged so that it is convex on the side opposite to the surface of the structure S, but as in the sixth embodiment shown in Figure 7(A), the hanger 32 may also be arranged so that it is convex on the surface side of the structure S.

[0047] In this way, when the hanger 32 is arranged convexly on the surface side of the structure S, the support surface of the electric wire C can be inclined by tilting the mounting angle of the hanger 32 relative to the runner bar 31, making it easier to guide the electric wire C at the end of the support hardware 3.

[0048] In particular, when the positions of the support member 2 and the hanger 32 overlap, the hanger 32 can be connected to the support member 2 with the bolts 41 and nuts 42, and the mounting angle can be easily changed.

[0049] Next, a case where the electric-wire laying electrical path 1 is the single electrical path shown in FIG. 1(B) will be described with reference to FIGS. 8(A) to 11(C).

[0050] Figure 8 shows a bolt fastening portion of a seventh embodiment, where (A) is a front view, (B) is a first modified example, and (C) is a second modified example. Figure 9 shows a bolt fastening portion of an eighth embodiment, where (A) is a front view, (B) is a first modified example, and (C) is a second modified example.

[0051] The electric cable 1 for laying electric wire according to the seventh embodiment shown in Fig. 8(A) and the eighth embodiment shown in Fig. 9(A) has leg portions 5 formed at the bent portion 34. The leg portions 5 may be formed integrally with the bent portion 34 by press molding or the like, or may be configured to be attached to the bent portion 34 later by welding or the like.

[0052] In the seventh embodiment shown in Fig. 8(A), the support metal fittings 3 are configured so as to be convex on the side opposite to the surface of the structure S (concave on the surface side of the structure S). In the eighth embodiment shown in Fig. 9(A), the support metal fittings 3 are configured so as to be convex on the surface side of the structure S.

[0053] When the support metal fittings 3 are arranged so as to protrude from the surface side of the structure S, the unevenness of the space G in which the electric wires C are laid can be reduced, making it easier to lay the electric wires C. In addition, by tilting the mounting angle of the support metal fittings 3 relative to the support member 2, the support surface of the electric wires C can be tilted, making it easier to guide the electric wires C at the end of the support metal fittings 3.

[0054] In the seventh embodiment shown in Fig. 8(A), the leg 5 is configured to have a shape equivalent to that of a channel steel. In a first modified example of the seventh embodiment shown in Fig. 8(B), the leg 5 is configured to have a shape equivalent to that of a C-shaped steel. In a second modified example of the seventh embodiment shown in Fig. 8(C), the leg 5 is configured to have a shape equivalent to that of a special shaped steel in which the tip of the bent part of a channel steel is rounded.

[0055] In the eighth embodiment shown in Fig. 9(A), the leg 5 is configured to have a shape equivalent to that of a channel steel.

In a second modified example of the eighth embodiment shown in Fig. 9(C), the leg 5 is configured to have a shape equivalent to that of a special shaped steel in which the tip of the bent part of a channel steel is rounded.

[0056] Figure 10 shows a bolt fastening portion of a ninth embodiment, where (A) is a front view, (B) is a first modified example, and (C) is a second modified example. Figure 11 shows a bolt fastening portion of a tenth embodiment, where (A) is a front view, (B) is a first modified example, and (C) is a second modified example.

[0057] The electric cable 1 for laying electric wire according to the ninth embodiment shown in Fig. 10(A) and the tenth embodiment shown in Fig. 11(A) has legs 5 formed on a support member 2. The legs 5 may be formed integrally with the support member 2 by press molding or the like, or may be configured to be attached to the support member 2 later by welding or the like.

[0058] In the embodiment shown in Figures 10(A) and 11(A), the leg 5 is configured to have a shape equivalent to a channel steel. In the modified example shown in Figures 10(B) and 11(B), the leg 5 is configured to have a shape equivalent to a C-shaped steel. In the modified example shown in Figures 10(C) and 11(C), the leg 5 is configured to have a shape equivalent to a special shaped steel in which the tip of the bent part of a channel steel is rounded.

[0059] In the ninth embodiment and its modifications shown in Figures 10(A) to 10(C), the support metal fittings 3 are arranged so that they are convex on the side opposite to the surface of the structure S (concave on the surface side of the structure S). In the tenth embodiment and its modifications shown in Figures 11(A) to 11(C), the support metal fittings 3 are arranged so that they are convex on the surface side of the structure S.

[0060] When the support metal fittings 3 are arranged so as to protrude from the surface side of the structure S, the unevenness of the space G in which the electric wires C are laid can be reduced, making it easier to lay the electric wires C. In addition, by tilting the mounting angle of the support metal fittings 3 relative to the support member 2, the support surface of the electric wires C can be tilted, making it easier to guide the electric wires C at the end of the support metal fittings 3.

[0061] In the embodiments and variants shown in Figures 10(A) to 11(C), it is assumed that the cable laying circuit 1 is a single cable laying circuit, but the cable laying circuit 1 may also be a ladder-shaped cable laying circuit in which the support metal fittings 3 have runner bars 31.

[0062] Furthermore, in the above-mentioned first to tenth embodiments (including modified examples), the leg 5 is described as being a channel steel, a C-shaped steel, or a special shaped steel with a rounded tip at the bent portion of the channel steel, or as having a shape equivalent to these shaped steels, but the configuration of the leg 5 is not limited to the configuration shown in the figure as long as a space G can be formed in which a spring force can act on the bolt fastening portion 4.
