Description

[Detailed Description of the Invention] (Industrial Application Field) This invention is called a hanger or a ducter channel for supporting electric wires or cables on the bottom surface of a floor plate called deck plate or keystone plate. The present invention relates to a suspension member supporting device for a floor plate suitable for installing a sliding support member having a lip channel steel shape.

(Prior Art) Conventionally, as a device for installing a sliding support member such as a hanger for supporting an electric wire tube, a cable or the like on a lower surface of a floor plate through a suspension rod member such as a suspension bolt or the like, Jpn. 12
A supporting device for a suspension rod member described in Japanese Patent No. 735 is known.

This device uses reinforcing ribs with a triangular cross-section that protrude downward from the bottom surface of the floor plate. Hangers are installed between the reinforcing ribs that face each other, and the rib tips that narrow the gap between them. The hanger is fixed by forcibly crimping both ends of the hanger at the part.

Further, as a similar hanging device, there is a hanging device for a cable rack in a deck plate for a concrete floor slab described in Japanese Utility Model Laid-Open No. 62-103912. This suspension device is provided with a holding portion that holds the side surface of the reinforcing rib from both sides,
The holding portion is provided with vertical pieces, and the hanger is installed between the vertical pieces.

(Problems to be solved by the invention) Therefore, in the conventional supporting device, it is necessary to cut both ends of the hanger diagonally in accordance with the inclination angle in order to press the reinforcing ribs into pressure contact between the inclined side surfaces. However, it is extremely difficult to uniformly process the end of the hanger by cutting work at a construction site, and as a result, there is a disadvantage that a constant supporting strength cannot be obtained.

Also, in order to press both ends of the hanger between the inclined side surfaces of the reinforcing rib, projecting a fixing screw for pressing on the upper surface of the hanger, and pressing the tip of this fixing screw against the bottom surface of the floor plate, The whole is forcibly moved to the tip side of the reinforcing rib. However, like this,
Since the gaps between the reinforcing ribs are used for crimping, if there is vibration or distortion in the floor plate itself, the gaps between the reinforcing ribs may expand and the hanger may loosen or fall. .

On the other hand, in the suspension device for the cable rack in the deck plate for the concrete floor slab, when the holding portion is attached to the side surface of the reinforcing rib, the work is performed from the bottom surface of the deck plate. Therefore, even if an attempt is made to attach the holding portion to the reinforcing ribs at the preset marking position, the holding portion itself hinders the marking check. Therefore, when the holding portion is mounted in a state where it does not accurately match the marking position, there is a disadvantage that the hanger cannot be erected on the holding portion via the vertical piece.

Therefore, this invention has been guided to solve the above-mentioned problems. It is easy to attach a sliding support member such as a hanger to a floor plate, and stable support strength is obtained. An object of the present invention is to provide a suspension rod member supporting device for a floor plate, which can be reliably supported even when it itself is vibrated or distorted, can be accurately mounted, and can enhance the efficiency of the mounting work.
