[Conventional technology and its problems]

When laying electric wires/cables, there are cases where the cables are suspended from a structure such as a ceiling.If the cable has a large diameter, the weight of the cable becomes large. As shown in the figure, a suspension support member is fixed to the tip of the electric wire/cable a, and an old wire fitting d having a locking hole C is attached near the tip of the cable a, and the suspension support A locking tool e of a pulling mechanism such as a winch or the like is locked to the member, and the cable a is pulled up to a predetermined position by the pulling mechanism, and then inserted into the locking hole C of the old cable d.
The locking device of another lifting mechanism such as a chain block is locked, and the suspension support member is brought closer to the locking member g of the frame f by being pulled up further.

Therefore, the locking device e for the suspension support member for the electric wire/cable a.
, and attach the suspension support member using a turnbuckle or other connecting metal fittings. II! Connecting the locking member g of the body f, and then
The locking tool and old wire fitting d had been removed.

Therefore, as mentioned above, the wire gripping device d must be attached to the wire/cable a, and two lifting mechanisms are required, and the locking device e and the locking device must be attached to the suspension support member and the wire gripping device, respectively. Since it was necessary to engage and disengage the tool d, the work was extremely troublesome and the work efficiency was poor.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a suspension support method that can solve these conventional problems and easily and quickly suspend electric wires and cables from a frame such as a ceiling.

[Means for solving problems]

The method for suspending and supporting electric wires and cables of the present invention is a method for suspending and supporting electric wires and cables in which the upper end or middle portion of the electric wires and cables is suspended from a locking member fixed to a frame such as a ceiling. After fixing a suspension support member having a hole for permanent suspension and a hole for temporary suspension to the upper end or middle portion of the cable, attach a locking tool of the lifting mechanism to the hole for temporary suspension of the suspension support member. The electric wire/cable is pulled up and held in a predetermined position by the lifting mechanism via the suspension support member, and in this state, the connection member is connected to the main suspension member via the connection member. Connect the holes, and then
Release the wire/cable from being held by the above-mentioned lifting mechanism,
The electric wires/cables are suspended from the above-mentioned structure.

[Effect]

According to the method of the present application, the locking tool of the lifting mechanism is locked in the temporary hanging hole of the suspension support member, and the electric wire/cable is pulled up and held at a predetermined position by the lifting mechanism, and the electric wire/cable is held in that state. , the wires and cables are suspended by connecting the main suspension hole of the suspension support member and the locking member of the frame with a connecting member such as a turnbuckle, so one pulling machine is required. In addition, there is no need to attach wire grips to the wires/cables.
