The construction method using a large crane requires a vast site area for installing the large crane. Further, in the construction method using a frame such as a gin pole, a temporary foundation, a pillar and a guide are required. Wires are required, and in the case of the construction method described in Japanese Patent Application No. 5-320055, similarly, a temporary foundation and temporary stanchions for lifting equipment are also required, both of which secure a site in a narrow construction ground. There is a problem that it is not possible to install a large crane, construct a frame such as a gin pole, or construct a lifting facility. In particular, when additional equipment and structures such as reactors and towers are installed due to the expansion of plants, the existing ground is very close and the construction ground is very small. Can not do it. Further, since the frame and the lifting equipment such as gin poles directly install the temporary support columns on the construction ground, a large amount of materials for the temporary structure will be required, and therefore, the labor burden required for the work is large, In addition, there is a problem that the work process is diversified and the cost is increased at the same time.

In view of the above-mentioned circumstances, an object of the present invention is to enable the construction of installation equipment in a narrow space of the construction ground, and at the same time, to provide equipment suitable for drastically reducing temporary materials and labor saving. It is to provide an installation method.

[0005]

[Means for Solving the Problems] The above-mentioned object is to install a pedestal on the top of equipment such as an existing reactor, fix a temporary support on this pedestal, and install an installation beam on the top of the temporary support. This is achieved by hoisting equipment such as a new reactor using the hoisting device attached to the installation beam and installing it at a predetermined location. Here, the existing equipment top and pedestal are fixed with bolts and nuts by a flange joint.

[0006]

The present invention makes it possible to construct installation equipment on top of existing reactors and other equipment, even in narrow spaces where installation work was difficult with conventional construction methods.
Installation work can be carried out smoothly, and by constructing installation equipment by using equipment such as existing reactors, it is possible to greatly reduce the temporary materials that form the installation equipment, and With a large reduction in materials, the amount of work is reduced, the work process is reduced, and as a result, labor is saved.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the present invention. In FIG.
The installation facility S includes two temporary columns 1 and 2, and temporary columns 1 and 2.
Temporary trays (installation beams) installed horizontally at the top of the
3, the lifting device 4 attached to the temporary tray 3. The two temporary columns 1 and 2 are erected on the tops 5-1 and 6-1 of the existing reactors 5 and 6, respectively. Here, the temporary columns 1 and 2 are composed of short column units bolted to each other. The hoisting device 4 hoists to install the new reactor 7 on the foundation base 8. As the lifting device 4, as shown in FIG. 4, a temporary tray (hanging beam)
A hoisting winch installed on the ground via a hoisting wire is used. In order to install the new reactor 7 on the foundation base between the existing reactors 5 and 6, the hoisting device 4 is operated, the new reactor 7 is hoisted by the hoisting winch (not shown) and installed on the foundation base 8.

FIG. 2 shows a detailed structure of a temporary support column to be erected and the top of the existing reactor. 2 (a) is a front plan view of the temporary support column and the top of the existing reactor, and FIG. 2 (b) is a plan view seen from above. On the top 5-1 of the existing reactor 5, a large H steel is arranged in a + character as the receiving stand 10 of the temporary support 1. A blind flange 9 or the like is welded and fixed to the intersecting portion of the + character-shaped large H steel. Here, the top portion 5-1 of the existing reactor 5 and the large H steel pedestal 10 are fixed by connecting the blind flange 9 and the flange 20 of the existing reactor 5 itself by using bolts and nuts 11. . Further, the four large H steel legs 10-1 of the pedestal 10 contact the top 5-1 of the existing reactor 5,
The temporary column 1 is erected on the four legs 10-1. The temporary columns 1 are square pipes 1-1, 1-2, 1-3, 1-, respectively.
4 and is configured to be divided into transportable lengths. The temporary support columns 1 may be reinforced by connecting them to each other using the cross beams 12 and the braces 13.

FIG. 3 is a plan view showing the inside of the site of an actual plant, and an example in which the present invention is applied to the site to newly install a reactor will be described. Here, the newly installed reactor 7 is newly installed at the point A as the reactor RT-101B. As is clear from FIG. 3, at the point A on the construction ground,
The existing reactors RT-101A and RT-100B are close to each other, and the heat exchanger HE- is installed next to these existing reactors.
102D and HE-102H are installed, and existing reactors RT-201A and RT-201B are inserted across a narrow open space, and also tower TW-102, Vessels VE-104 and VE.
-105 is installed. The narrow open space is not large enough to install a crane, nor is it an area where a frame such as a gin pole or conventional lifting equipment can be constructed. Also, GR
-100 represents grating. In this way, existing reactors, heat exchangers, vessels, and towers are installed close to each other within the premises of the illustrated plant, and since the open space is small, large cranes can be installed, and frames and lifting equipment such as gin poles can be installed. There is a situation where it cannot be built. Therefore, when newly installing the new reactor 7, in this embodiment, first, the grating GR-100 is temporarily removed to secure a space in which the new reactor 7 can be carried. Next, the existing reactors RT-101A and RT adjacent to the point A on the construction ground
Each existing reactor RT-101 using -100B
The installation equipment S described above as the present embodiment is erected on the top of the A, RT-100B, the hoisting device 4 is attached to the installation equipment S, and the hoisting device 4 is operated, as shown in FIG. As described above, the new reactor 7 is lifted and then suspended on the foundation foundation 8 and installed at the point A on the construction ground. The load applied to the existing reactor during this work is in the vertical direction, and there is no problem in strength. In this way, when the reactor is additionally installed with the expansion of the plant, when the construction ground is very narrow and the installation work cannot be performed by the conventional construction method,
In the present embodiment, it is possible to construct an installation facility by using an existing plant adjacent thereto, and install and install a new reactor or the like with this installation facility.

In this embodiment, the reactor is described as a new installation device, but as a new installation device,
There are various plant devices such as towers and structures and structures, and they can be applied when installing various plant devices such as these devices and structures. Further, it goes without saying that the present embodiment can be effectively applied to the installation of various various equipment other than the installation of various plant equipment. Also,
In this embodiment, the installation equipment is described as being built on the top of the existing reactor, but it is needless to say that the installation equipment may be built on the top of not only the existing reactor but various other various devices.

[0011]

As described above, according to the present invention,
Even in a narrow place where installation work is difficult with the conventional construction method, installation equipment can be constructed on top of various equipment such as an existing reactor, and installation work can be performed smoothly. In addition, since various types of equipment such as an existing reactor are used to construct the installation equipment, it is possible to significantly reduce the amount of temporary materials that form the installation equipment, as compared with the case where the equipment is erected directly on the construction ground. This is especially effective when a long object such as a reactor or tower is newly installed. Also, the work volume has been reduced due to the significant reduction in temporary materials,
Since the number of work steps is reduced, the labor can be saved, the cost of temporary materials can be reduced, and the cost can be reduced. Further, in the installation equipment of the present embodiment, the installation work is limited to a narrow range, so that the area where entry is prohibited at the time of work is narrow, in other words, the safety range can be wide.
