Description

The present invention relates to a support fitting mounting tool that can safely and easily mount a cable support fitting or the like used for preceding wiring work to a hanging bolt or the like.

For example, in an office building or the like, pre-wiring work may be performed to lay cables before the ceiling is attached. In this construction, a support bracket is attached to the suspension bolt suspended from the ceiling in advance, and a cable is wired to the support bracket.

As one of the support metal fittings for wiring the cable, for example, there is a cable drop prevention device previously proposed by the applicant (Patent Document 1). This support metal fitting is a support metal fitting that includes a connecting body that is fixed to the side surface of the suspension bolt and a support body that supports the cable, and supports the cable on the side surface of the suspension bolt.

The connecting body of the support metal fitting has a structure in which a pair of upper and lower notch locking openings are formed on the longitudinal side surface of the elastic band-shaped metal fitting. Then, in the work of attaching the connecting body to the hanging bolt, when the hanging bolt is passed through the upper and lower notch locking openings with the longitudinal end of the band-shaped metal fitting compressed, and the compressed state is released, the elastic force of the band-shaped metal fitting is restored. In addition, the upper and lower notch locking ports are locked to the hanging bolt, and the connecting body is fixed to the hanging bolt.

When such an installation work is performed at a high place near the ceiling, the worker manually performs it while using a stepladder or the like. However, since support brackets are attached to a large number of hanging bolts in the cable wiring work, the work process involves repeating movement and setting, which requires a lot of work time. Moreover, the work of attaching the connecting body of the band-shaped metal fittings to the hanging bolt is the work of keeping the longitudinal end of the band-shaped metal fittings strongly compressed by the fingers, and a large grip strength by the fingers is required, so a large number of metal fittings are attached. It takes a lot of effort. In particular, since the work is performed at a high place, there is always a risk of falling or the like.

In order to ensure the safety of workers in such aerial work, it is necessary to be able to work from the floor with a telescopic rod or the like without using a stepladder or the like. As a conventional mounting tool for aerial work, for example, the mounting tool described in Patent Document 2 has been proposed.

The attachment tool of Patent Document 2 is an attachment tool for fixing a support tool for supporting a cable or the like to a hanging bolt suspended from a double ceiling or the like. This support has a pair of upper and lower holding portions, and the suspension bolts are alternately held in the holding portions. Therefore, in order to fix the support to the suspension bolt, tilt the support attached to the mounting tool with respect to the suspension bolt, place the suspension bolt between the pair of holding parts, and then return the support vertically. Then, the support is fixed to the hanging bolt.

However, as in Patent Document 2, even if a tool for attaching a support bracket for fixing a bolt body inside the upper and lower embedding portions has been proposed, a support bracket having a configuration that can be easily attached by compressing the strip-shaped bracket is provided. Tools for mounting at heights have not been proposed so far.

In particular, the work of compressing the connecting body of the support bracket is an operation of passing the hanging bolts through the upper and lower locking openings while keeping the longitudinal end of the strip-shaped bracket compressed with the fingers, and releasing the hand to release the compressed state. It has become. Such an operation is a simple manual operation, but in order to perform this series of operations from the floor without using a stepladder or the like, it is necessary to remotely control the elastic force of the band-shaped metal fitting and attach it to the hanging bolt. There is. Therefore, a tool for attaching this kind of support metal fitting to a high place has not been proposed so far.

Therefore, the present invention was created to solve the above-mentioned problems, and it is possible to remotely control the support metal fittings having a structure in which elastic metal fittings such as band-shaped metal fittings are compressed and mounted, without using a stepladder or the like. The purpose is to provide mounting tools for support brackets that can be mounted from above the floor to high places.

In order to achieve the above object, the first means in the present invention includes a connecting body P1 of elastic metal fittings fixed to the side surface of the rod-shaped body Q and a support P2 for supporting the cable R or the pipe, and the elasticity of the connecting body P1. A support metal fitting mounting tool for mounting the support metal fitting P, in which the connecting body P1 is fixed to the rod-shaped body Q by force, to the rod-shaped body Q.

The mounting tool of the present invention is a mounting tool used when mounting a support metal fitting P for supporting a cable or a pipe on a side surface of a wire rod such as a rod-shaped body Q at a high place.

The support metal fitting P operated by the mounting tool of the present invention is intended for the support metal fitting P having a configuration that can be easily mounted by the work of compressing the elastic metal fitting. For example, it includes a connecting body P1 of a band-shaped metal fitting fixed to the side surface of the rod-shaped body Q and a support P2 for supporting the cable R or the pipe. Further, a support metal fitting that is sandwiched from both side surfaces of the rod-shaped body by the elastic force of the elastic metal fitting may be used. At this time, the rod-shaped body Q can be arbitrarily selected from linear members for fixing the support metal fitting P, such as hanging bolts and metal wires.

The illustrated elastic metal fitting has a connecting body P1 of the strip-shaped metal fitting. Then, when the rod-shaped body Q is passed through the pair of upper and lower notch locking ports P3 formed on the longitudinal side surfaces of the connecting body P1, the connecting body P1 is fixed to the rod-shaped body Q by the elastic force of the connecting body P1. Yes (see Figure 9).

The main configuration of the mounting tool of the present invention for mounting such a support metal fitting P is a configuration including an operation pole 10, a metal fitting holder 20, and a string body 30 (see FIG. 1).

The operation pole 10 is a rod-shaped member provided with a fixing screw portion 11 at the upper end of a stretchable rod, and the metal fitting holder 20 is detachably connected to the fixing screw portion 11 (see FIG. 2). The operation pole 10 and the metal fitting holder 20 may be fixed in advance. In the illustrated example, a string body 30 for remote control is attached to the operation pole 10 (see FIG. 1). That is, one end of the string 30 is provided with a connecting hook 31 to be connected to the fixing release portion 22, which will be described later, and the other end is wound around the ring-shaped holder 32 (see FIG. 10).

The holder 32 is provided with a sandwiching portion 32A, and the side surface of the operation pole 10 is sandwiched between the sandwiching portions 32A and slidably mounted. At the time of operation, the holder 32 attached to the operation pole 10 is operated with a finger to enable remote control of the string body 30. In addition to using a rope, a wire, or the like, the string body 30 can be replaced with a thin rod-shaped object.

The metal fitting holding body 20 is a member including a holding portion 21 and a fixing release portion 22 (see FIG. 2). The holding portion 21 is provided on the metal fitting holding body 20 so as to be slidable up and down, and is a portion for holding the upper and lower end portions of the connecting body P1.

The illustrated holding portion 21 is composed of a mounting portion 21A and a locking portion 21B (see FIG. 3). The mounting portion 21A is a portion on which the lower end portion of the connecting body P1 is mounted, and is formed on the side surface of the metal fitting holder 20. On the other hand, the locking portion 21B is a portion pivotally supported by the protrusion-shaped fixing portion 21C so as to be vertically movable, and is a substantially L-shaped portion that slides on the upper portion of the mounting portion 21A. Then, the locking portion 21B is applied to the upper end portion of the connecting body P1 mounted on the mounting portion 21A, and the connecting body P1 is slid and moved in the direction of compression as it is (see FIG. 4).

Further, the holding portion 21 is formed at a position protruding in the side surface direction from the position connected to the operation pole 10 (see FIG. 2). By forming the holding portion 21 at this position, when the support metal fitting P is attached to the rod-shaped body Q, for example, even if the rod-shaped body Q suspends the channel material, the support metal fitting P can be attached while avoiding the channel material. It will be possible. Further, even if another obstacle is nearby, it can be avoided, and the remote control of the support metal fitting P can be facilitated.

Further, in the vicinity of the holding portion 21, a guide 23 used for mounting the held support metal fitting P to the rod-shaped body Q is provided. The illustrated guide 23 has a substantially plate-like shape protruding from one side of the holding portion 21 (see FIG. 2). Then, when the metal fitting holding body 20 is operated so that the rod-shaped body Q applied to the guide 23 approaches the support metal fitting P while the support metal fitting P is held by the holding portion 21, the inside of the notch locking port P3 of the support metal fitting P is operated. The rod-shaped body Q is easily introduced into the body (see FIG. 7). The guide 23 may be provided on both sides of the holding portion 21.

The fixing release portion 22 is a member that fixes the position of the holding portion 21 in a compressed state of the connecting body P1 (see FIG. 4). Further, the fixing release portion 22 is also a member for releasing the position of the fixed holding portion 21 (see FIG. 3). That is, when the string body 30 connected to the fixing release portion 22 is pulled, the position of the holding portion 21 fixed by the fixing release portion 22 in the compressed state is displaced and the compressed state is released.
(The holding portion 21 is matched to the expression of the claim. The locking portion 21B is described by 0032.)

In this way, when the fixed position of the holding portion 21 is released, the notch locking port P3 of the connecting portion P1 is restored when the connecting portion P1 is restored while sliding the holding portion 21 upward by the elastic force of the connecting portion P1. The support metal fitting P is fixed to the rod-shaped body Q passed through the (see FIG. 9).

The illustrated fixing release portion 22 is a fixing body 22A that overlaps and fixes the upper end portion of the connecting body P1 on the upper portion of the locking portion 21B at the compressed position, and the fixing body 22A is swingably connected to the metal fitting holding body 20. (See FIG. 2).

The fixed body 22A is formed of a plurality of protrusions extending in a swinging direction (see FIG. 2). Then, when the fixed body 22A swings to the top of the locking portion 21B, the fixed body P1 is pressed at the position of the compressed state of the connected body P1 to fix the connected body P1 (see FIG. 4). At this time, the operator manually swings the fixed body 22A up to the locking portion 21B. Further, although not shown, the fixing body 22A is fixed when the locking portion 21B is pushed down by attaching a spring material that constantly presses and urges the fixing body 22A toward the locking portion 21B to the fixing release portion 22. It is also possible to configure the body 22A to automatically swing over the locking portion 21B. Further, the fixed body 22A shown in the figure is provided with a locking portion 22D. The locking portion 22D is a protruding portion that engages with the locking portion 21D recessed in the upper surface of the locking portion 21B when the locking portion 21B is fixed.

The connecting body 22B of the fixing release portion 22 is a portion that is provided integrally with the fixing body 22A and is swingably connected by a swinging shaft 22C provided on the metal fitting holding body 20 (see FIG. 2). In the illustrated example, the fixed body 22A and the connecting body 22B form a substantially inverted U-shaped fixing release portion 22. Then, when the fixing release portion 22 swings by remote control of the string body 30, the fixing body 22A is configured to be disengaged from the upper part of the locking portion 21B (see FIG. 3).

Further, although not shown, when the metal fitting holder 20 is oriented sideways and the connecting body P1 mounted on the holding portion 21 is sandwiched from the left and right, it is sandwiched by the elastic force of the elastic metal fitting from both side surfaces of the rod-shaped body. It is also possible to operate the type of support bracket to be worn.

Next, the procedure for using the mounting tool of the present invention will be described with reference to FIGS. 5 to 9. As shown in FIG. 5, the support metal fitting P is attached to the holding portion 21.

As shown in FIG. 6, the locking portion 21B is pressed downward to compress the connecting body P1, and the fixing body 22A is covered and fixed on the locking portion 21B. In this state, the connecting body P1 is held in the holding portion 21 in a compressed state.

Further, as shown in FIG. 7, the rod-shaped body Q is passed through the notch locking port P3 of the connecting body P1 held in the holding portion 21. In this state, the connected body P1 is still kept in a compressed state.

Then, as shown in FIG. 8, when the string body 30 is pulled by remote control, the fixing release portion 22 swings and the fixing body 22A moves from the upper end of the locking portion 21B. Then, the connected body P1 in the compressed state is restored to the state before compression while pushing up the locking portion 21B by its own elastic force.

Finally, as shown in FIG. 9, the support metal fitting P is fixed to the rod-shaped body Q inserted into the notch locking port P3 by the elastic force at the time of restoration of the connecting body P1.

11 and 12 show another embodiment of the fixing release portion 22. That is, the fixing release portion 22 forms a lateral fixing rod 22E to be inserted into the through hole 21E formed on the side surface of the locking portion 21B. At this time, the locking portion 21B is formed through the through-hole 21E into which the fixing rod 22E is inserted. Then, the fixing rod 22E is inserted into the through port 21E of the locking portion 21B in which the upper end portion of the connecting body P1 is compressed to fix the locking portion 21B (see FIG. 11). Further, although not shown, by attaching a spring material that constantly presses and urges the fixing release portion 22 toward the through opening 21E, the locking portion 21B is pushed down to automatically fix the fixing portion 22 to the through opening 21E. It is also possible to allow the 22E to be plugged in.

To release the locking of the locking portion 21B, pull the locking release portion 22 by remote control of the string body 30, and the fixing rod 22E is pulled out from the through port 21E (see FIG. 12). Then, the elastic force of the connected body P1 in the compressed state returns to the connected body P1 having the original shape.

13 and 14 show other usage examples of the metal fitting holder 20. That is, the metal fitting holding body 20 is provided with an operating body 40 for operating the cable R. The operating body 40 further includes an upper locking portion 41 and a lower locking portion 42.

The upper locking portion 41 forms a protrusion protruding upward from the metal fitting holder 20, and is used when the cable R is lifted and locked to the support P2 of the support metal fitting P (see FIG. 13). On the other hand, the lower locking portion 42 forms a protrusion protruding downward from the metal fitting holder 20 and is used when arranging the cable R locked to the support P2 (see FIG. 14).

The configuration of the operation pole 10, the metal fitting holding body 20, and the string body 30 of the present invention, and the configurations of the holding portion 21, the fixing release portion 22, and the like are not limited to the illustrated examples. Further, the support metal fitting P to be attached according to the present invention is not limited to the one for supporting the cable, but also includes the support metal fitting P for supporting the pipe, and the shape of the support P2 can be arbitrarily changed. As described above, design changes are free without changing the gist of the present invention.
