Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a support structure in which a support is installed in a pit in order to provide a space at the bottom of the installation seat of a power distribution board, in particular, a power distribution board or other similar panel. This invention relates to an installation seat for a power distribution board, etc., configured to install a power distribution board, etc. through the installation seat.

[Prior art]

An example of a conventional installation seat of this type is as follows:
As shown in Figure 1.

That is, in the figure, code 1 is the foundation;
After the support bolt 2 is installed on the foundation 1, the edge metal fitting 3 is supported by the threaded part 2a of the head thereof, and its height is adjusted. On the other hand, the intervals between the edge hardware 3 are set by baseboards 4, and a formwork 5 is attached to one end of the baseboards 4.
A concrete wall 6 is constructed by pouring concrete between the section surrounded by the edge hardware 3 and the formwork 5 and the foundation 1.

A panel mounting frame 7 configured at a predetermined height is installed within the concrete wall 6 configured in this manner to constitute an installation seat for a switchboard or the like.

In addition, the code|symbol 8 is a switchboard, and 9 is a checker plate.

Since the conventional installation seat is constructed as described above, all the support bolts 2 of the edge metal fittings 3 are embedded in the concrete wall 6, making it uneconomical, and the height adjustment of the panel mounting frame 7 is not possible until the panel mounting Legs 7a of rack 7
and the foundation 1. Therefore, leveling work requires a high level of skill and a lot of time. In setting the dimensions, the thickness of the mortar that will be applied later must be taken into account when determining the dimensions, and therefore, the dimensions have many drawbacks, such as requiring a lot of effort.

[Summary of the idea]

The purpose of the present invention is to eliminate the drawbacks of the conventional installation seats for switchboards, etc., as described above, and to obtain an economical installation seat for switchboards, etc., which is simple and easy to work with. The frame is supported by a height adjustment device that is removably supported inside the frame and can be adjusted in the height direction by screw engagement, and the formwork is arranged at intervals of a thickness corresponding to the thickness of the mortar. By attaching it to the skirting board via a piece, thereby forming a concrete wall, and supporting the panel mounting frame in a height-adjustable manner by screw engagement, the adjustment device can be used repeatedly. The purpose of the present invention is to provide an economical installation seat for a power distribution board, etc., which makes it easy to determine the dimensions of baseboards, and also makes it easy to adjust the height of the panel mounting frame, making the work simple, easy, and economical.

[Example of idea]

Hereinafter, the present invention will be explained based on the drawings showing one embodiment thereof.

In Fig. 2, the foundation 1, edge hardware 3, switchboard 8, and checker plate 9 are the same as those in the conventional installation base, and the reference numeral 11 is a baseboard, which is detailed in Fig. 3. As shown, the edge hardware 3 supports the sides of the edge hardware 3 at a predetermined distance, and is made of a piece of wood or a plastic material, such as a piece of foamed plastic, with a thickness corresponding to the thickness of the mortar that will be applied later on the end face. A spacer piece 12 consisting of is attached, and a plate-shaped formwork 13 made of, for example, a plywood board is attached to the side of the spacer piece 12 to form a frame.

Further, the vertical support of the edge hardware 3 is supported and adjusted by a height adjustment device 14, as shown in FIGS. 4 and 5. The height adjustment device 14 includes, for example, a base 16 having a female thread formed therein and whose lower end is attached to the substrate 15;
A support shaft 18 is formed with a male thread that engages with a female thread of the frame, and has a support part 17 that is rotatably provided at the upper end.
It is formed into a frog straddle so as to sandwich one vertical side of the . Note that reference numeral 19 is a handle for rotating the support shaft 18 and raising and lowering the support shaft 18 by means of screws engaged with each other, and 20 is an insert. Further, the height adjustment device 14 is not limited to the above-mentioned configuration, and may be any height adjustment device using screw engagement.

Next, reference numeral 21 denotes a panel mounting rack on which a switchboard 8, etc. configured as shown in FIG. ing. This support column 22 is attached to a base material 23 and has a base 25 in which a female thread 24 is formed inside, for example.
and an upper support 27 which has a male thread 26 mating with the female thread 24 formed on the outer diameter portion of the lower end and supports the panel mounting frame 21 at the upper part. By moving, the upper support column 27 expands and contracts, thereby making the panel mounting rack 21 horizontal. The threaded engagement strut 22 is not necessarily limited to the structure described above, and may be any strut configured to expand and contract by the mutual rotation of the engaged screws.

The installation seat of the present invention is composed of the above-mentioned members, and the method is as follows: After placing the height adjustment device 14 at a predetermined location in the pit of the foundation 1, , turn the handle 19 to level the edge hardware 3, and
A skirting board 11 with spacer pieces 12 of the same thickness as the mortar is provided between them so that the edge hardware 3 is spaced at a predetermined distance, and then a plate-shaped formwork 13 is attached to the spacer pieces 12. Next, after pouring concrete between the plate-shaped formwork 13 and the foundation to form a concrete wall 28, the baseboard 11, plate-shaped formwork 13, and height adjustment device 14 are removed. Interpolation line 2
0 firmly fixed to the concrete wall 28.

Next, after installing the support 22 in a predetermined position and placing the panel mounting rack 21 on it, the upper support 27 of the support 22 is rotated to level the panel mounting rack 21 and maintain that state. , panel mounting rack 21
and the upper strut 27, and between the male thread 26 and the female thread 24, for example, by welding or the like.

Note that once these operations are completed, the base material 23 is fixed with mortar or the like.

[Effect of idea]

Since the installation seat of the present invention is constructed as described above, the dimensions of the skirting board can be determined directly based on the design values, and the mortar thickness can be freely determined separately from this. Leveling of the edge hardware and panel mounting rack is extremely simple and easy, and the height adjustment device can be used repeatedly, which has the effect of providing an economical installation seat for a switchboard, etc.
