Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a wiring duct mounting device used for suspending a wiring duct.

[Background technology]

Wiring ducts are often suspended from construction materials using hanger-type attachment devices.

Figures 4 to 7 show an example of this, and in Figure 0, ■
is a hanger member, and has a pair of continuous leg pieces 1a at the upper end.
, lb, and a hook portion 2 is formed by curving inward at the lower end. In addition, duct holding pieces 3 are cut and raised on both leg pieces 1a and Ib. The hanger member 1 is connected to the lower end of a hanging bolt 4 by sandwiching it between a pad 5.6 and a washer 7, and the hanging bolt 4 is attached at its upper end to a building material 13 with nuts 8, 9 and a washer IO. Wiring duct 11
(FIG. 6), the hanger member 10 is swallowed between both leg pieces 1a+1b, suspended by the hook portions 2 at the lower ends of the leg pieces 1a and 1b, and is pressed from the upper surface by the duct holding piece 3.

With this conventional structure, the hanging bolts 4 tend to swing laterally, and therefore, when wiring ducts 11 of a fixed length are connected and constructed in a line as shown in Fig. 7, meandering occurs as shown in the figure. This may occur. This results in a very poor appearance and also affects the reliability of the mutual connections of the wiring ducts 11. This meandering is the length of hanging bolt 4! The longer the period, the more likely it is to occur;
It is extremely difficult to construct it straight.

Further, as shown in FIG. 6, when the plug 12 is attached to the wiring duct 11 and a lateral force (in the direction of the arrow X) is applied from the outside, the plug 12 swings and meanderes.

Therefore, we proposed a system that would attach two stays 15 to stop the vibration, as shown in Figure 8. However, in places where the height level of the lower surface of the construction material 13 is not high, the construction material 1
Since the height dimension l between 3 and the hanger member 1 varies,
It was not possible to use stays 15 of the same length, making construction difficult.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a wiring duct mounting device that can prevent the wiring duct from swaying or meandering in the lateral direction, and can be installed regardless of variations in the height of construction materials.

[Disclosure of the Invention] The wiring duct mounting device of the present invention comprises: a hanger member for suspending a wiring duct; a hanging bolt whose lower end is coupled to the hanger member and whose upper end is fixed to a building material; and a hanging bolt that is in contact with the construction material. an upper steadying member fixed to the hanging bolt and extending in both lateral directions with respect to the wiring duct; a lower steadying member attached to the lower end of the hanging bolt and having a width shorter than the upper steadying member; Two rope members are provided diagonally stretched between both ends of the steady rest member and the lower arm rest member.

According to this configuration, the two cables are stretched diagonally between the upper resting member extending in both lateral directions with respect to the wiring duct at the top of the hanging bolt, and the lower steadying member at the lower end of the hanging bolt. The tension of the cables on both sides prevents the suspension bolt from swinging laterally. Therefore, horizontal deflection and meandering of the wiring duct are prevented. Furthermore, since rope material is used, the length can be adjusted freely, unlike when using stays. Therefore, even if the height level of construction materials varies, construction can be easily carried out according to the variation in height.

Embodiment An embodiment of the present invention is shown in FIGS. 81 to 3, and this wiring duct installation device includes a hanger member 1 for suspending a wiring duct 11, a lower end is connected to the hanger member 1, and an upper part is a construction material. Hanging bolt 4 fixed to 13 and construction material 1
Wiring duct 1 is fixed to hanging bolt 4 in contact with the lower surface of 3.
1, a lower steadying member 21 attached to the lower end of the hanging bolt 4, and a lower steadying member 21 between both ends of the upper restraining member 20 and the lower steadying member 21. It is equipped with two cable members 22 stretched diagonally. This wiring duct attachment device is provided at a plurality of locations in the longitudinal direction of the wiring duct 11.

Since the hanger member 1 is the same as the example shown in FIGS. 4 and 5, the same reference numerals are given and the explanation thereof will be omitted. As shown in FIG. 3, the upper rest member 20 has a notch 24 in the center through which the hanging bolt 4 is inserted, and bent pieces 2 at both ends.
5 is provided. The bent piece 25 is provided with a cable fixing hole 26. The downrest member 21 has a notch 27 in the center through which the hanging bolt 4 is inserted, and rope material retaining holes 28 at both ends. The upper rest stop member 20 is fixed to the construction material 13 together with the suspension bolt 4 by fitting the notch 24 onto the suspension bolt 4 while contacting the lower surface of the construction material 13, and using 2III nuts 8 and 9 (FIG. 2). 10 is a washer. The downrest member 21 is stacked on the upper surface of the hanger member 1, and the hanging bolt 4 is fitted into the notch 27, and is fixed to the hanging bolt 4 together with the hanger member l by two slots 7) and 5.6.

The cable material 22 is made of wire lobes or the like, and has both ends connected to the cable material fixing holes 26.
28 and stop with the stopper 29. The stopper 29 is made of, for example, a cylindrical member external to the cable material 2, and is fixed to the cable material 22 by crimping with a crimping tool.

The wiring duct 11 is the same as that of the conventional example described above, and its structure will be explained here. That is, wiring duct 1
1, as shown in FIG. 2, consists of a duct body 11' formed by providing an insulating coating on a groove-shaped core, and two types of conductors 18 and 19 provided within this duct body 11'. Each conductor 1
8.19 is partially exposed and embedded in the insulation coating.

According to this configuration, the wiring duct 1 is connected to the upper part of the hanging bolt 4.
Since the two rope members 22 are tensioned diagonally between the upper rest member 20 extending in both lateral directions relative to 1 and the lower end member 21 of the lower end of the hanging bolt 4, the tension of the cable members 22 on both sides is This prevents the suspension bolt 4 from swinging in the lateral direction. Therefore, the wiring duct 11 is prevented from swinging or meandering in the lateral direction. Furthermore, since the cable material 22 is used, the length can be freely adjusted unlike when using a stay. Therefore,
Even if the height level of construction materials 13 varies, construction can be easily carried out according to the variation in height.

Furthermore, in this embodiment, the upper rest stop member 20 is attached to the hanging bolt 4 with a nut 8.9, so unlike the proposed example, there is no need to provide an upper rest stop member mounting hole in the construction material 13. , Moreover, the upper and lower photo-preventing members 20
Since the suspension bolt 4 is passed through the notch 24, the wiring duct 11 can be easily installed without being disassembled after the wiring duct 11 is constructed without providing the steady rest member 20, 21. Therefore, when meandering occurs, this wiring duct attachment device can be used only at that location, and the pond location can be simply suspended using the hanging bolts 4.

Installation after construction is carried out as follows.First, loosen the nut 9 of the upper rest stop member 20, and then attach the washer 10 and construction material 1.
Insert it into the gap in step 3 and tighten it securely. Similarly, the nut 6 of the downward rest stop member 21 is loosened, and the nut 6 is inserted and fixed. After the installation of the upper and lower steady rest members 20 and 21 is completed, the cable material 22 is passed through the cable material fixing hole 26 as shown in FIG.

〔Effect of the invention〕

The wiring duct installation device of the present invention includes an upper heating member extending in both lateral directions with respect to the wiring duct at the upper part of the hanging bolt;
Since the two ropes are tensioned diagonally between the lower end of the hanging bolt and the downward sway prevention member, the tension of the ropes on both sides prevents the hanging bolt from swinging in the lateral direction. Therefore, horizontal deflection and meandering of the wiring duct are prevented. Also, since rope material is used, the length can be adjusted freely, unlike when using stays. Therefore, even if the height level of construction and materials varies, the construction can be easily carried out according to the variation in height.
