Description

  In the present invention, for example, in order to route various cables along the wall surface in a road tunnel, when the support member is installed in large numbers at predetermined intervals on the wall surface as a support member serving as a pedestal, The present invention relates to a cable support that can be supported and fixed easily and quickly, and can be stably maintained for a long period of time without rotating even if it is fixed in a one-point support state, and also can be easily managed.

  Conventionally, when a cable or the like is wired along a tunnel wall surface, for example, it is supported by being placed so as to be bridged between support base members attached to the wall surface at predetermined intervals. As such a pedestal member, for example, there is an electric cable laying support tool (Patent Document 1) according to Design Registration No. 1194898, and a cable rack according to Japanese Patent No. 5175596 and a method for constructing a cable rack on a tunnel wall surface (Patent Document 2). )

  The support of Patent Document 1 is provided with a predetermined band so that an upper open groove-shaped cable support piece is connected to a fixing piece in which a fixing hole fixed to a tunnel wall surface is opened. It is integrally formed by bending a plate material. This support is fixed to a wall surface by screwing a screw member having a fixing hole inserted into an anchor member embedded in a wall surface position corresponding to a support site, and contacting the fixing piece to the wall surface, and a cable or the like on the cable supporting piece. Is to be passed. In addition, the cable rack of Patent Document 2 includes a mounting body having a lower opening that can be fixed along a cable laying direction, and a cable erection arm portion that protrudes from a plurality of locations of the mounting body and includes reinforcing portions. Are integrally formed of fiber reinforced plastic. In this cable rack, the mounting plate at the bottom of the mounting body is fixed to the wall by screwing it, and the cable is placed on the installation arm. This eliminates the need for a support member that is a separate member as a base that is fixed to the wall surface.

Design Registration No. 1194898 Japanese Patent No. 5175596

  According to such a conventional support tool of Patent Document 1, when using a power tool that rotates a screw member when screwing and fixing a fixing piece to a wall surface, the cable support piece provided below the fixing piece is an obstacle. Therefore, the electric tool cannot be set, and it is necessary to perform manual work. Moreover, since this is spread over a large number of places, the whole work becomes troublesome and the work efficiency becomes poor. In addition, for example, when carrying and storing a large amount of support tools at the installation site, it is impossible to superimpose a plurality of support tools themselves, so each of them must be handled individually and becomes bulky. The management is complicated. Moreover, according to the cable rack of Patent Document 2, the rack itself is too large when supporting a large number of cables, even if a large number of cables are supported, and the installation work at the site is rather troublesome. This is inconvenient because it cannot cope with the adjustment and change of the support interval for installing the cable. Furthermore, in the cable rack itself, each one rack itself is formed in a so-called comb shape, and therefore it is difficult to collect them in a compact manner by stacking them when carrying in the field as in the case of the support of Patent Document 1. , Handling and management are also cumbersome.

  Therefore, the present invention was created in view of the above-described conventional circumstances, and the purpose thereof is, for example, one-point screwing that is supported at one point on the tunnel wall surface, and is simply supported and fixed by an electric tool. It is possible to improve the efficiency of work, and even if it is a single point support, not only can it be maintained for a long time without rotating, but also the supports themselves can be superposed on each other, even if there are multiple It is suitable for supporting a large number of cables, etc. on the tunnel wall, which can be compactly packed, is easy to carry in and handle on site, and secures safety to prevent falling. An object of the present invention is to provide a cable support.

In order to solve the above-described problems, the present invention will be described with reference numerals used in the embodiments for carrying out the invention to be described later, and fixed to be abutted and fixed to the wall surface W of the tunnel. An inclined wall that is bent upward and wide at the end via a partition piece 6 that is bent in a mountain shape so as to travel upward at the upper end of the fixed piece 2 in which the hole 3 is opened. A cable support piece 5 having a shape of a shallow groove that opens upward together with the piece 7 is integrally bent with a strip material having a predetermined thickness and width, and the lower end of the fixed piece 2 is bitten into the wall surface W. The anti-rotation part 4 is formed.
The fixing hole 3 can be configured to be located below the position of the cable support piece 5 supported by the fixed piece 2 that is positioned in contact with the wall surface W.
The rotation preventing portion 4 can be formed by bending the lower end portion of the fixed piece 2 toward the wall surface W side.
The cable support piece 5 can be provided with a fall prevention means 10, which comprises a connection member 12 having an insertion hole screwed into a connection hole 11 opened in the cable support piece 5, and The connecting wire 12 is inserted into the connecting member 12 and fixed to the wall surface W.
A plurality of fixed pieces 2, cable support pieces 5, and partition pieces 6 are overlapped with each other, the other fixed piece 2 is overlapped on one fixed piece 2 to be overlapped, and the other on one partition piece 6. The other cable support piece 5 is overlapped on the one cable support piece 5 and brought into contact with each other, and this is repeated so that a predetermined number of pieces are put together. Can be configured.

In the cable support according to the present invention configured as described above, for example, when various wiring members C are erected along the wall surface W in the road tunnel, they are brought into contact with the wall surface W and screwed. Even if the fixing piece 2 is supported at one point by the screwing member (B) fitted in the fixing hole 3, the rotation preventing portion 4 of the fixing piece 2 bites into the wall surface W to rotate the cable support 1 itself. The wiring member C placed on the cable support piece 5 formed integrally with the fixed piece 2 is reliably supported.
The cable support piece 5 supported by the fixing piece 2 placed in contact with the wall surface W is positioned below the cable support piece 5 and the fixing hole 3 is opened in the fixing piece 2. For example, the electric power tool M brought from below to operate the screwing member (B) fitted to 3 is not interfered with or disturbed by the cable support piece 5.
The fall prevention means 10 attached to the cable support piece 5 does not drop the cable support 1 itself even if the screwing support state by the fixing hole 3 in the fixed piece 2 is lost, and improves the safety at the time of attachment.
Further, since none of the fixed piece 2, the cable support piece 5, and the partition piece 6 is in a closed shape, the fixed pieces 2, the cable support pieces 5, and the partition pieces 6 are overlapped with each other, and a predetermined number Make it compact even if it exists.

  Since the present invention is configured as described above, for example, when supporting a wiring member C such as a cable erected along the wall surface W in a road tunnel, the support is fixedly supported at predetermined intervals along the wall surface W. These can be safely and reliably supported. In addition, the cable support 1 itself is not rotated even if it is supported at one point on the wall surface W, and the fixing position is maintained, and the power tool M can be used from below the cable support 1 itself during the fixing support work. Can greatly improve work efficiency. In addition, it is integrally formed by bending with a band-shaped material with a predetermined thickness and width, and by overlapping each other, a plurality of them can be gathered together in a compact manner, transported, transported to the installation site, and its member management In addition, it is possible to improve the mounting stability and safety by providing the fall prevention means 10.

  That is, in the present invention, a shallow groove that opens upward together with the inclined wall piece 7 via the mountain-shaped partition piece 6 at the upper end of the fixing piece 2 having the fixing hole 3 that is fixed to the wall surface W by abutting and fixing. The cable support piece 5 having a shape is integrally bent with a strip material having a predetermined thickness and width, and the anti-rotation portion 4 that bites into the wall surface W is formed at the lower end of the fixed piece 2. It is. This makes it possible to stably maintain the fixed position without rotating even if the single-point support is fixed to the wall surface W by three fixing holes, improve the work efficiency by using the electric power tool M at the time of fixing, and overlap when there are multiple The ease of member management and the like due to the compactization can be obtained.

  Further, since the fixing hole 3 opened in the fixing piece 2 is located below the position of the cable support piece 5 supported by the fixing piece 2 which is positioned in contact with the wall surface W, the fixing piece 2 is attached to the wall surface W. For example, when the screwing operation is carried out with the electric power tool M, the operation is not hindered by the cable support piece 5 itself even if it is brought from below the cable support tool 1 itself. Together with one-point support by the part, even when a large number of predetermined intervals are attached to the wall surface W, the attaching operation can be performed very efficiently.

  In addition, even if the fixing hole 3 is supported at one point, the fixing piece 2 itself is attached to the wall surface W because the lower end of the fixing piece 2 is formed with the anti-rotation portion 4 that is hooked into the wall surface W. When abutting and fixing, the wiring member C on the cable support piece 5 can be stably supported for a long time without rotating around the fixing hole 3 as a fulcrum. Further, since the rotation preventing portion 4 is formed by bending the lower end portion of the fixed piece 2 to the wall surface W side, one edge of the fixed piece 2 is caught on the wall surface W, and the fixed piece 2 itself is strong against the wall surface W. In combination with fixing by screwing, the rotation prevention function is also increased, and since it is bent, no separate member is required and the configuration is simple.

  The fixed piece 2 and the cable support piece 5 are placed on the cable support piece 5 because the division piece 6 bent in a mountain shape is formed so as to travel upward at the upper end of the fixed piece 2. The wiring member C does not interfere with the wall surface W, and the cable support piece 5 has a shallow groove shape that is open upward along with the inclined wall piece 7 that is bent upward at the end of the cable support piece 5. Therefore, the work of laying through the wiring member C is not only smooth, but it is not dropped off, and its supporting state is stable.

  The fall prevention means 10 attached to the cable support piece 5 includes a connection member 12 having an insertion hole screwed into the connection hole 11 opened in the cable support piece 5, and a wall surface W inserted through the connection member 12. For example, even if the screw fixing function at the fixing hole 3 is lost, the cable support 1 itself is suspended and supported by the fall prevention means 10. The support 1 itself and further the wiring member C and the like do not fall and are safe.

  Since the fixed piece 2, the cable support piece 5, and the partition piece 6 are all open and not closed, the fixed pieces 2 in the plurality of cable supports 1, the cable support pieces 5, and the partition pieces 6 Even if the cable support 1 according to the present invention has a plurality of predetermined numbers, the cable support 1 can be gathered in a compact manner, and it is not necessary to create a useless space during transportation, and can be carried into the installation site. Not limited to, on-site member management and the like can be easily performed.

  In addition, the code | symbol attached | subjected in each means of the means for solving said subject and the effect of invention was attached | subjected in order to make easy reference with the part which shows each structure part described in drawing. The present invention is not limited to these descriptions, structures, shapes, and the like indicated by reference numerals and the like in the drawings.

Similarly, it is a front view when a plurality of supports according to the present invention are overlapped and put together in a compact manner.

  Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings. Reference numeral 1 shown in the figure is a cable support according to the present invention, and the cable support 1 is, for example, a wall surface in a road tunnel. A fixed piece 2 that abuts and is fixed to W, and a cable support piece 5 that carries and supports a wiring member C such as a cable that is bent and connected to the fixed piece 2. For example, it is integrally formed by bending a strip-shaped steel piece material.

  The fixed piece 2 is formed in a flat plate shape so as to abut on the wall surface W, preferably in close contact with it, and is anchored embedded and fixed so as to protrude from the wall surface W in accordance with the attachment location of the cable support 1 itself. A fixing hole 3 for fitting and positioning to a screwing member B such as a bolt is opened, and a rotation preventing portion 4 whose one edge is abutted against the wall surface W is bent at the lower end portion. ing.

  The fixing hole 3 is, for example, formed in a vertically long shape at substantially the center position of the fixed piece 2 and can adjust the vertical position at the time of fixing, and is positioned when the fixed piece 2 itself is in contact with the wall surface W. The screwing member B, which is positioned below the cable support piece 5 to be fitted in the fixing hole 3, can be screwed in without being disturbed by the cable support piece 5 and being obstructed. It is.

  The anti-rotation part 4 is formed by slightly bending the lower end portion of the fixed piece 2 itself with respect to the fixed piece 2 at, for example, about 5 degrees. The locking property to be caught with respect to the wall surface W by the rotation preventing portion 4 is obtained. Of course, the bending angle and the bending length of the rotation prevention unit 4 itself are not particularly limited. When the fixed piece 2 is screwed and brought into contact with the wall surface W in a pressing manner, the rotation prevention unit 4 is brought into contact with the wall surface W. It is sufficient that the fixed piece 2 itself is prevented from rotating by being bitten.

  Further, the cable support piece 5 is attached to the fixed piece 2 via a partition piece 6 bent in a mountain shape so as to travel upward by being directed downward from the upper end of the fixed piece 2 once. Is fixed to the wall surface W so as to be horizontally parallel to the ground. In addition, the cable support piece 5 itself is gradually inclined outward as it reaches the outer side at the end portion, so that the shallow wall groove shape that is open upward together with the inclined wall piece 7 that is bent upward and widened. Presents. The depth and width of the cable support piece 5 correspond to the number of placement / accommodation of wiring members C having a predetermined diameter to be supported, and are arbitrarily selected. For example, in a tunnel having a horseshoe shape in cross section, when supporting the wiring member C in the vicinity of the lower part, the cable support piece 5 is at an angle that is almost perpendicular to the fixed piece 2, and the same when supporting the wiring member C in the vicinity of the ceiling. The cable support piece 5 is bent and connected to the fixed piece 2 at an angle close to horizontal, and these are selected in accordance with the attachment location.

  Further, the cable support 1 can be assembled with a fall prevention means 10 for supporting the wiring of the wiring member C safely and reliably by the cable support 1. As shown in FIG. 4, the fall prevention means 10 is a connection having an insertion hole such as an eyebolt screwed to a connection hole 11 opened in the vicinity of a partition piece 6 in the cable support 1 itself, for example, the cable support piece 5. The member 12 includes a connecting wire 13 that is inserted into the connecting member 12 and is fixed to the wall surface W, for example. The cable support 1 itself is supported by fixing both ends of the connection wire 13 inserted into the connection member 12 screwed and fixed to the cable support 1 to the wall surface W or the like. Even when the support structure of the fixed piece 2 is lost due to damage due to an earthquake or the like, the cable support 1 itself is supported and the wiring member C or the like is not dropped.

  The cable support 1 itself including the fixed piece 2, the cable support piece 5, and the like described above is formed in an open shape by bending each band plate material having a predetermined thickness and width. As shown in FIG. 5, a plurality of pieces are stacked, and even if there are a plurality of pieces, they can be gathered together in a compact manner. That is, for example, the other fixed piece 2 is overlapped on the fixed piece 2 in one cable support 1 so that the other divided piece 6 covers the one divided piece 6 and on the one cable supported piece 5. The other cable support piece 5 is overlapped with the other, and the other inclined wall piece 7 is further overlapped with the one inclined wall piece 7 to be brought into contact with each other, and this is repeated so that a predetermined number of cable support members 1 are overlapped with each other. It can come together in a state.

  Next, an example of the use thereof will be described. For example, in a road tunnel, the fixing piece 2 is aligned with a screwing member B attached and fixed at predetermined intervals to a wall surface W corresponding to a portion to be supported by the wiring. Then, the cable support 1 is fixed to the wall surface W in a state where the rotation preventing portion 4 is pressed against the wall surface W. At this time, as shown in FIG. 3, the electric power tool M for screwing brings the fixing piece 2 into close contact with the wall surface W by direct positioning with respect to the screwing member B by the fixing hole 3 of the fixing piece 2 and is efficient. The cable support 1 itself is attached to the wall surface W according to a proper work procedure. Next, a predetermined number of wiring members C are placed on the cable support piece 5 so that the wiring members C can be bridged and fixed by an appropriate band material as necessary.

  Furthermore, the cable support 1 itself may be prevented from falling by the fall prevention means 10 for inserting the connecting wire 13 fixed to the wall surface W into the connecting member 12 such as an eyebolt fixed to the connecting hole 11.
