Description

[Detailed Description of the Invention] The present invention relates to an installation device for installing electrical equipment such as a transformer or an accelerator indoors.

Conventionally, when installing this type of electrical equipment indoors, the equipment installation surface (floor surface) is equipped with an embedded base 1 (as shown in Figure 1).
Although only one is shown in the figure, generally multiple pieces are installed, for example, in the direction of the page, except for the parts where concrete is poured.

6 shows horizontal reinforcing bars embedded in the concrete part.

The part where concrete is not poured is called box removal.

Then, a plurality of embedded bases 1 are inserted into the boxed-out floor and installed so that the upper surface (equipment installation surface) of the embedded bases 1 is horizontal and all embedded bases 1 are at the same level. .

Since it is extremely difficult to level a concrete floor and maintain the same level over the entire equipment installation surface, generally the embedded base 1 is leveled with adjustment bolts 8, and then the equipment is installed horizontally. There is.

After the installation of the embedded bases 1 is completed, these embedded bases 1 are filled with concrete and fixed.

Next, the electrical equipment 3 is placed on the embedded base 1 via the electrical equipment base 4, the anchor bolt 2 is inserted into the deepest part 9 of the box cutout, and the electrical equipment base 4 and the anchor bolt 2 are tightened. Tighten with bolt 5.

After that, concrete is poured into the deepest part 9 of the box cutout to complete the installation around the foundation of the electrical equipment 3.

In such equipment installation, the aforementioned anchor bolt 2
is quite long to prevent the device 3 from falling or sliding due to an earthquake, so the depth of the box cutout where the anchor bolt 2 is inserted needs to be considerably deep, and depending on the size of the device 3, it may be 1 m or more. It may be exceeded.

For this reason, the thickness of the floor must be made thicker than the design value of the building compressive strength due to the length of the anchor bolt 2, which not only requires a large amount of concrete and reinforcing steel, but also in the case of a basement. There were disadvantages such as having to dig deeply.

This invention was made to eliminate the above-mentioned drawbacks.
To provide an installation device for electrical equipment that can withstand overturning and skidding of equipment due to earthquakes, and can economically construct a building without making the floor thicker than necessary.

An embodiment of the present invention will be described below with reference to FIG.

Incidentally, in FIG. 2, the same parts as in FIG. 1 are indicated by the same reference numerals.

In the present invention, a plurality of embedding plates 10 that are substantially flush with the embedding base 1 are arranged at locations corresponding to the positions of the conventional anchor poles 12.

Next, inside the floor of the building, horizontal reinforcing bars 6 are arranged in length and breadth over the entire surface in order to give the floor strength.

Next, concrete is placed on these reinforcing bars 6 to finish the floor surface. At this time, 50 mm to 100 rrvn of the outer periphery of the embedded base 1 and the embedded plate 10 is placed on one side.
Concrete is poured with sufficient clearance.

Further, a plurality of vertical reinforcing bars 7 are welded to the horizontal reinforcing bars 6 at the location where the embedded plate 10 is installed.

Note that the size and number of the vertical reinforcing bars 7 are determined so as to withstand overturning and side-sliding of the electrical equipment 3 during an earthquake.

After completing the concrete pouring of the floor surface other than the box cutout 11 of the embedded base 1 and the embedded plate 10, insert the embedded base into the box cutout 11, and use the adjustment bolt 8 to level the embedded base 1. While leveling, the vertical reinforcing bars 7 are inserted into the perforations previously provided in the embedded plate 10.

At this time, the vertical reinforcing bar 7 is placed at the drilling position of the embedded plate 10.
If they do not match, the vertical reinforcing bars 7 may be bent appropriately.

After aligning the top surface level of each embedded plate 10 with the top surface level of the embedded base 1, vertical reinforcing bars 7 are attached to the embedded plate 1.
Weld to the hole 0.

After the embedded plate 10 is integrated with the reinforcing bars 6 inside the floor by welding in this manner, the box cutouts 11 are poured with concrete to finish the floor surface.

After the concrete on the floor hardens, the electrical equipment 3 is placed on the embedded base 1 and the embedded plate 10, and the equipment base 4 and the embedded plate 10 are fixed by welding, or, although not shown in the figure, A female thread is provided in the embedded plate 10 in advance, and the electric device 3 is mechanically coupled to the embedded plate 10 by tightening and fixing it from the device base 4 with bolts.

With such a configuration, the embedded base 1 bears the weight of the electrical equipment 3, and the embedded plate 10 bears the weight of the equipment from falling or sliding due to an earthquake. 10 is integrated with the reinforcing bars 6 and 7 inside the floor, and the electrical equipment 3 is fixed to the embedded plate 10 by welding or bolts, so there is no worry about it falling over or skidding due to an earthquake. Therefore, since there is no need for long anchor bolts as in the past, the thickness of the floor can be increased, and the inferior quality of building materials such as reinforcing bars and concrete can be measured.

As detailed above, according to the present invention, the thickness of the floor of the building where electrical equipment is installed can be determined by the building design, and there is no need to worry about electrical equipment falling over or sliding due to an earthquake. It is possible to provide an installation device for electrical equipment that has excellent effects.
