Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention mainly relates to a method for arranging and installing a plurality of control panels and the like on a floor surface.

[Prior art]

Generally, a concrete floor surface has uneven parts and is not a horizontal surface. In such a location, it is not easy to arrange a plurality of control panels with their head levels aligned in an attractive manner.

Conventionally, in order to install a control panel on a floor surface, as shown in FIG. 1, the concrete floor surface 1 is first chiseled with a chisel or the like to expose the slab reinforcing bars 2. Next, the standing reinforcing bars 3 are erected on the slab reinforcing bars 2 by welding. Then, a vibration-proof rubber 5 having a round cross section (or a rectangular shape may be used) is fastened to the lower surface of the channel base 4 with a nut 6. Next, the standing reinforcing bars 3 are welded to the bolts 7 protruding from the lower ends of the seismic rubber 5. At this time, level adjustment and horizontal positioning of the channel base 4 are performed simultaneously. Next, the lower part of the seismic rubber 5 is surrounded by a formwork (not shown), and mortar 8 is filled and hardened. Next, a control panel (not shown) was placed and fixed on the channel base 4 to complete the process.

[Problem to be solved]

However, this method requires chiseling and mortar filling work, especially indoors.
Dust, vibration, and humidity were generated, deteriorating the working environment. At the same time, it was time-consuming and troublesome. Furthermore, because the number of man-hours required for on-site work is large and it is difficult to standardize the work, variations in work accuracy are likely to occur. Therefore, the horizontality of the channel base 4 tends to be out of order, and readjustment is often required, which is troublesome.

[Means for solving problems]

The present invention adopts the following configuration in order to eliminate the above problems.

That is, the upper end closed surface of the metal upper cylinder 12 is fixed to the lower surface of the channel base 4 for installed equipment, and the metal lower cylinder 13 is slidably fitted to the upper cylinder 12 in the vertical direction. It is placed on a metal plate 10 fixed in advance on a concrete floor surface, and then the channel base is aligned so that the channel base 4 is placed in a predetermined position. 13, the upper cylinder body 12, and the metal plate 10 are welded together.

〔Example〕

Next, one embodiment of the present invention will be explained with reference to FIG.

The method of the present invention uses two cylinders, upper and lower, and the equipment is installed on the floor as follows. Second
As shown in the figure, first, when constructing the concrete floor 1, a metal plate 10 is welded to the slab reinforcing bars 2 via the foot reinforcing bars 9. After that, concrete is poured, concrete floor surface 1 and metal plate 10
and are formed on almost the same plane. Next, insert the upper and lower bolts 11 and 7 of the seismic isolation rubber 5 into the bolt insertion hole 16 of the channel base 4 and the bolt insertion hole 17 for fixing the installed equipment in the metal upper cylinder body 12, and fasten them with the nut 6. do. Next, the metal lower cylinder 13 is fitted onto the upper cylinder 12, and the lower cylinder 13 is placed on the metal plate 10. next,
The channel base 4 is leveled and aligned in the horizontal direction. At this time, the upper cylindrical body 12 and the lower cylindrical body 13 slide, and the lower cylindrical body slightly horizontally moves the metal plate 10 due to level adjustment and the like. Next, with the level adjustment and the like completed, the lower cylinder 13 and the upper cylinder 12 are point welded 14. Therefore, the vertical adjustable distance of the channel base 4 is equal to the height of the upper cylinder 12. Generally, it is sufficient to weld the upper cylindrical body 12 and the lower cylindrical body 13 by performing point welding of about 3 mm at four locations every 90 degrees around the upper end of the lower cylindrical body 13. Therefore,
If it becomes necessary to re-level the channel base 4, it can be easily done by cutting the point weld 14. In addition to the above welding, the lower cylindrical body 13 and the metal plate 10 are point welded 15 to complete the installation method of the present invention. Note that the present invention is of course not limited to the above embodiments, and for example, the inner diameter of the upper cylinder body 12 is
The outer diameter of the lower cylindrical body 13 is slightly larger than that of the upper cylindrical body 12.
It is also possible to have a structure in which it is inserted into. Furthermore, each of the cylinders 12 and 13 may be cylindrical, oval, or rectangular. Especially if it is cylindrical,
Each cylinder used in this method can be easily manufactured using existing iron pipes and the like. Alternatively, the seismic rubber may be omitted.

〔Effect of the invention〕

The present invention has the above configuration and has the following effects. This method uses a metal upper cylinder 12 to which an installed device is fixed, and a metal lower cylinder 13 that is slidably fitted onto the upper cylinder 12. This lower cylindrical body 13 is placed on a metal plate. Therefore, in the installation method of the present invention, if the metal plate 10 is fixed to the concrete floor surface 1 in advance, the upper and lower cylindrical bodies 12 and 13 will slide as the levels are adjusted. The equipment can be reliably and easily installed on the floor with only extremely simple welding to secure it. And, like the conventional installation method,
To eliminate the need for chiseling work or mortar filling work on a concrete floor surface 1. Therefore, it is effective to prevent dust, vibration, moisture, etc. that are generated during conventional installation work, and to maintain a good working environment. Furthermore, construction work is simplified and installation accuracy is improved. Along with that,
The simplification of construction allows for quick installation of control panels, etc., which has significant effects.
