Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for installing a heavy object on a foundation such as a floor surface.

Conventionally, when installing a heavy object weighing over 100 ky on a foundation such as a floor, a guide pin (h) is placed on the foundation surface (α) as shown in Figure 1, and the guide pin (h) is placed on the foundation surface (a). and heavy objects (
The heavy object (C) was gradually lowered to the foundation surface (α) using the guide pin (h) as a guide by operating the jack bolt (d) disposed across C).

Therefore, the conventional method requires a large amount of work space to operate the jack bolt (d-), and a large number of heavy objects (
When installing C), it was not possible to arrange them densely.

Wood brother! rt biThis was proposed to solve these problems.The heavy object is supported on the installation base via a balloon-shaped hydraulic jack that expands and contracts with the pressure of the enclosed fluid, and then the inside of the jack is The present invention relates to a method for installing a heavy object, characterized in that the fluid pressure is gradually reduced to lower the heavy object onto the installation base.

In the present invention, as described above, the M scenic object is supported on its installation base via a balloon-shaped fluid pressure jack that is inflated and deflated by the pressure of the fluid enclosed between the two, and then the jack is By gradually reducing the pressure and deflating, the heavy object on the jack is gradually lowered onto the installation base, and is then installed on the same base.
Therefore, since the front fluid pressure jack can be remotely operated, heavy objects can be arranged very densely, and the installation area can be significantly reduced.

The present invention will be described below with reference to the illustrated embodiments.

Place the packer plate (2) on the heavy object installation base (1).
and a guide pin (3) are attached, and a balloon-shaped hydraulic jack (4) is provided surrounding the knob bumper plate (2) and guide pin (3).

The jack (4) is made of a Jumbo or the like, is formed in a donut shape, and is connected to a liquid or air pipe (6) with a valve (5) interposed therebetween.

After press-fitting liquid or air pressure into the jack (4) until the required pressure is reached, a heavy object (
6), and place the same weight object (6) on the jack (4).

Next, the valve (5) is opened, the liquid or air in the hydraulic jack (4) is gradually removed, and the heavy object (6) is lowered onto the packer plate (2) using the guide 9 bin (3) as a guide. Then remove the guide pin (3), tighten the heavy object (6) and packer plate (2) with the foundation bolts, and complete the installation of the heavy object (6).

Note that the donut-shaped hydraulic jack (4) is left as it is even after the heavy object (6) is installed.

In addition, when using a C-shaped jack as shown in Fig. 5 as the hydraulic jack (4), it is removed after the installation of the heavy object (6) is completed, and then reused when another heavy object (6) is installed. used.

According to the method of the embodiment, when the heavy object (6) is lowered onto the packer plate (2), the liquid or air can be vented by remote control from the hydraulic jack (4) that supports the heavy object (6). Therefore, as shown in FIG. 2, heavy objects (6) can be arranged very densely, and the installation area can be significantly reduced.

In the conventional method, a work space with a width of at least 600 fin widths is required around each heavy object in order to operate the jackboot for installing heavy objects.
It is sufficient to allow for a width of about Q'1llllll.

As shown in FIG. 3, the installation area S when square-shaped heavy objects (1) with a side dimension of U is installed in n rows and X columns with an interval B is given by 5-LXXLY.

Therefore, LX =]l, y=yl'[J-)-(rL-1
) B, so S = lr+, U+(n, -x)B)
” becomes.

Therefore, since the installation area S of a 1 m knee II drawing is S-Merck, it is as follows.

If we assume that JP=(U+(], -B) is now U-1m and Le=25, in the case of the conventional method, B=0.6m, so -?=2.

On the other hand, in the case of this method, As B=Q, Q5yx #=1.10.

Therefore, according to this method, the installation area per one weight chest is less than W, and the larger the value, the thicker the effect.

Although the present invention has been described above with reference to embodiments, the present invention is of course not limited to such embodiments, and can be modified in various ways without departing from the spirit of the invention. be.

Claims (1)

[Claims] A heavy object is supported on the installation base via a balloon-shaped hydraulic jack that expands and contracts with the pressure of the enclosed fluid, and then the fluid pressure inside the jack is gradually reduced to place the heavy object on the installation base. A method for installing heavy objects characterized by lowering them.
