Description

[Detailed Description of the Invention] The present invention relates to a scaffolding device used for laying cables on a cable tray provided on a ceiling.

Cable trays are generally suspended from the ceiling, and therefore require scaffolding equipment for laying cables on the cable trays.

Conventionally, in such cases, scaffolding was assembled from the ground to the cable tray position and the cables were laid. However, this method requires large-scale scaffolding, and requires a great deal of effort to assemble and dismantle, so in recent years, scaffolding has been removably attached to side wall members, etc. for various scaffolding operations, and removed after the work is completed. Segmented and assembled scaffolding devices that can be transported have been considered and have been used to great advantage in certain application conditions.

However, the width of the cable tray varies depending on the amount of cables laid there, the distance between the side wall and the cable tray also varies, and there is also a duct or other structure adjacent to the cable tray. In some cases, various types of equipment are installed, and in such cases, even if you try to apply a split-assembly scaffolding device like the one described above, it will be difficult to install it because the width of the bottom of the scaffolding cannot be changed. In some cases, it is not possible to do so, resulting in inconveniences such as having to separately prepare a scaffolding device that matches the width dimension, or assembling only that part of the scaffolding from the ground as in the past.

The present invention has been developed to eliminate such inconveniences, and the stanchion is attached to a horizontal pin provided at one end of the scaffold board mounting table through a long hole extending in the longitudinal direction of the stanchion so that it can be raised and lowered freely. At the same time, a fall prevention fitting part for inserting and locking the lower end of the erected stanchion is fixed below the pin of the scaffold board mounting base, and the fitting part is fixed to the required position of the scaffold board mounting base along the longitudinal direction thereof. A long hole for attaching a scaffold is formed, and a nut is housed in a guide member fixed to the scaffold plate mounting base along the long hole for attaching a scaffold so that the nut can be moved along the long hole for attaching a scaffold. This relates to scaffolding equipment.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 5, a scaffold board mounting table 2 having a pin support part 1 bent at a right angle at one end is provided, and the pin support part 1 on the scaffold board mounting table 2 is provided.
Scaffold mounting long holes 3 and 4 are provided along the longitudinal direction of the scaffold board mounting table 2 at a required distance from the other end at a required distance from the platform. Scaffold mounting long hole 3,
4 are formed on both sides of the scaffold board mounting base 2, as shown in FIGS. Nuts 7, 7 which can be moved along the long holes 3, 4 for attaching the scaffolding are housed therein.

Further, on the side of the pin support part 1 of the scaffold mounting table 2, as shown in FIGS.
8, and elongated holes 10, 10 are formed in the support legs 8, 8 along the axial direction of the stanchion 9, and the elongated holes 10, 10 and the ends of the pin support part 1 are connected to each other. By connecting the stanchions 9 with pins 11, the stanchion 9 is foldably mounted parallel to the scaffold board mounting base 2. Further, at the end of the scaffold board mounting base 2 on the side where the stanchion 9 is attached, there are provided a fall-prevention fitting part 12 into which the lower ends of the support legs 8, 8 of the stanchion 9 are fitted, and fall-prevention members 13, 14. By the pin 11, the falling prevention fitting part 12, and the falling prevention members 13 and 14,
The scaffold board mounting table 2 and the stanchion 9 are configured to be able to be firmly held at right angles. In the figure, reference numeral 15 indicates a clamp provided to attach the handrail pipe 16 to the stanchion 9.

Figures 6 and 7 show an example of a cable tray frame 23 to which the present invention is applied, which includes hanging members 18, 18 whose upper ends are fixed to the ceiling 17 by welding or bolts, and It is composed of a cross member 20 made of an appropriate number of angle members connected between the members 18 and 18 to support an appropriate number of cable trays 19. In addition, the lowermost angle member of the horizontal member 20 described above has, at both end positions thereof, and at a position included in the length range of the scaffold mounting slots 3 and 4 formed in the scaffold board mounting base 2. Scaffold mounting holes 21, 2
form 2. Cable tray frame 23 mentioned above
Construction, formation of the scaffolding mounting holes 21 and 22, etc. are performed in advance at a factory or the like. In the figure, 24 indicates a scaffold board, and 25 indicates an obstacle.

The operation of the scaffolding device of the present invention having the above configuration will be explained.

The scaffolding device of the present invention is changed from the folded state shown by the imaginary line shown in FIG. 1 to the expanded state shown by the solid line. At that time, the stanchion 9 is erected around the pin 11 so that it is perpendicular to the scaffold board mounting base 2, and then the stanchion 9 is moved downward, and the support legs 8,
8 fits into the anti-falling fitting part 12, whereby the pin 11, the anti-falling fitting part 12 and the anti-falling member 1
3 and 14, the stanchion 9 is locked at right angles to the scaffold board mounting base 2.

Subsequently, the elongated holes 3 and 4 for attaching the scaffold of the scaffold plate mounting base 2 in the scaffolding device in the expanded state as described above are replaced with the scaffold attaching hole 21 formed in the lowermost horizontal member 20 of the cable tray frame 23, 22, then insert the mounting bolt (not shown) into the scaffolding mounting hole 2.
1 and 22, screwed into nuts 7 and 7, and tightened, thereby attaching the scaffolding device to the cable tray frame 23. At this time, since the long holes 3 and 4 for scaffold attachment have a long tolerance range, even if the width dimension of the cable tray frame 23 changes as shown by the broken line in FIG. 7, the nuts 7, The scaffolding device can be easily attached to the cable tray frame 23 by simply changing the position of 7. Furthermore,
Even when the distance between the cable tray frame 23 attached to the ceiling part 17 and the side wall or other obstacle 25 is small, the tightening positions of the bolts and nuts 7, 7 can be changed along the long holes 3, 4 for mounting the scaffold. By doing so, the stanchion 9 can be connected to the cable tray frame 23.
The scaffolding board 24 can be mounted by adjusting the interval at which the scaffolding board 24 is placed to be narrow in advance. Also, at this time, the necessary parts of the scaffolding device are attached, for example, the handrail pipe 16 is attached via the clamp 15, the scaffolding board 24 is attached to the scaffolding board mounting table 2, etc.

As described above, the cable tray frame 23 to which the scaffolding device is attached is fixed by attaching the upper ends of the hanging members 18, 18 to the ceiling portion 17 by welding or the like. At this time, since a scaffolding device is immediately attached to the cable tray frame 23, work such as laying the cables into the cable tray 19 and covering the cable tray 19 using the scaffolding device is performed immediately. I can do it.

After the site work is completed, loosen the bolts screwed into the nuts 7 and 7, and attach the scaffolding device to the cable tray mount 23.
Remove from. The scaffolding device removed from the cable tray frame 23 includes the handrail pipe 16 and the scaffolding board 2.
4, etc., by pulling the stanchion 9 upward and pulling out the support legs 8, 8 from the fall prevention fitting part 12, rotating the pin 11 as shown by the imaginary line in FIG. Can be folded.
Since it can be folded in this way, it is easy to handle and transport, the space required for temporary storage can be reduced, and it is also easy to carry in and out of narrow spaces where it is difficult to swing. . In addition, during field work, small parts such as nuts are easily lost, but as mentioned above, nuts 7,
7 is stored in the scaffold board mounting base 2, so there is no chance of the powder being lost.When attaching the scaffolding device to the cable tray frame, you can use bolts that are highly versatile and easy to obtain even if they are lost. All you have to do is prepare. Furthermore, in the case of FIG. 1, two nuts 7, 7 are provided for one adjustment slot 3 or 4, so that they can be used even if the nuts 7, 7 are damaged.
I am trying to set up 7.

FIG. 8 shows another embodiment of the present invention, in which the elongated hole for attaching the scaffold formed in the scaffold plate mounting base 2 is one elongated elongated hole 26, and the elongated hole for attaching the scaffold 26 has a plurality of elongated holes ( In the illustrated case, four nuts 7 are provided including a spare one. Further, in order to prevent the strength of the scaffold board mounting base 2 from decreasing due to the formation of the scaffold mounting slot 26, a reinforcing member 27 is provided in the middle of the scaffold mounting slot 26 to connect the upper and lower parts. There is.
Such reinforcing members 27 can also be provided in the elongated holes 21 and 22 for attaching the scaffold in the embodiment shown in FIG. 1 to reinforce the scaffold board mounting base 2. Also the 9th
Figures A, B, C, D, and E each show an example of how the scaffolding board mounting base 2 is attached to the horizontal member 20 of the cable tray frame 23, and the connection between the horizontal member 20 and the scaffolding board mounting base 2 is changed. It can also be installed flexibly.

It should be noted that the present invention is not limited to the above embodiments, but can be applied to various works such as duct frames, ceiling conveyors, building steel construction, bridge construction, etc., and can also be applied to frames to which scaffolding devices are applied. etc., and that the assembly and disassembly procedures may be changed as necessary, such as by attaching scaffolding devices, handrail pipes, scaffolding boards, etc. to the structure, etc. after it is installed on the site, and the elongated hole part for attaching the scaffolding. Of course, it is possible to simply form a long hole without housing a nut therein, and to make various other changes without departing from the gist of the present invention.
