構造の上方から下方へと順次設置して行く。この方法は
、総ての作業を高さ方向で行い、通常は装置を空中で組
立てるため、比較的長い時間を必要とする。As is well known, the assembly of devices of this type requires the distribution of the various parts of the device over a considerable height, making the operation relatively complex and time-consuming. In the known method, the upper part of the device is first installed, and then the remaining parts are installed successively from the top to the bottom of the structure. This method requires a relatively long time since all operations are carried out in the height direction and the device is usually assembled in the air.
本発明の目的は、より安全な条件で、より多くの作業員
を現場で同時に作業させるようにして、ボイラをより短
い時間で組立てることにある。The aim of the invention is to assemble a boiler in a shorter time under safer conditions and by allowing more workers to work simultaneously on site.

々に持ち上げ、種々の中央部材を地上数メートルの位置
に順次配置することを特徴とする。The method of the present invention involves arranging and temporarily assembling the central and peripheral parts of the ceiling covering the device, while installing the supports of this ceiling, disassembling the two parts, and placing the peripheral part in its final position. At the same time, a boiler is installed in the central part, a reservoir is installed in the peripheral part, and the floor and ramp above are installed.
ers et passerelles) and accessories, and then the central part of the ceiling is gradually raised to the height of its final position, and the various central parts are placed one after another at a position several meters above the ground.
ボイラの上方部分の足場は、天井の周縁部分から下方へ
向かって徐々に組立てるのが好ましい。Preferably, the scaffolding in the upper part of the boiler is assembled gradually downward from the peripheral part of the ceiling.
以下、添付図面に基づき非限定的実施例を挙げて、本発
明の組立て方法の一連の操作を詳細に説明する。Hereinafter, a series of operations of the assembly method of the present invention will be described in detail using non-limiting examples based on the accompanying drawings.
現場で行う第１の操作は、設置すべきボイラの場所を囲
んで４つの支柱１．２．３．４を建てることからなる。The first operation carried out on site consists of erecting four columns 1.2.3.4 surrounding the location of the boiler to be installed.
次いで、中央部分５と周縁部分６とを含むボイラの天井
を組立てる。この天井は、金属製中央大梁７．８と、金

る。The roof of the boiler, including the central part 5 and the peripheral part 6, is then assembled. This ceiling consists of a metal central beam 7.8, a metal peripheral beam 9.10.11.12.13.14, a metal central beam, e.g. beam 15.16, and a metal peripheral beam 9.10.11.12.13.14. For example, the beams 17 and 18 are included. These beams are interconnected by removable connecting members, for example members 19, 20, 21.
第１図の鎖線は、いわゆるボイラ１２とそのリザーバ２
３の組立て完了後の輪郭を示している。The dashed line in Fig. 1 indicates the so-called boiler 12 and its reservoir 2.
3 shows the outline after assembly is completed.
第２の操作では、支柱の頂上に符号２４．２５．２６．

一方で、天井の中央部分５を中間の高さまで持ち上げる
。In the second operation, the symbols 24.25.26.
Attach a hydraulic jack as shown at 27 (Fig. 2), remove the removable connecting member, and use the jack to raise the peripheral portion 6 of the ceiling to the top of the column and place it in the final position, while Lift section 5 to mid-height.
天井の周縁部分にジヤツキ３１．３２（第３図参照）を
取付け、これらのジヤツキを用いて天井の中央部分５を
徐々に持上げる。天井の中央部分の上昇に伴って、ボイ
ラの中央部材、例えば上方ボックス３４及びエコノマイ
ザ３５も順に持ち上げていく。Attach jacks 31, 32 (see FIG. 3) to the peripheral edge of the ceiling, and use these jacks to gradually lift the central portion 5 of the ceiling. As the central portion of the ceiling rises, the central members of the boiler, such as the upper box 34 and economizer 35, are also lifted in sequence.
次いで下記の操作を同時に行う（第４図参照）。Then, the following operations are performed simultaneously (see Figure 4).
ボイラの周縁部材、例えば床とタラップ３３を、天井の
周縁部分から下方に向かって組立てて行く。The peripheral members of the boiler, such as the floor and ramp 33, are assembled downward from the peripheral part of the ceiling.
その一方で、リザーバを配置する。Meanwhile, place the reservoir.
ボイラを徐々に持上げながら地上数メートルの所で操作
して、ボイラの中央部材、特に水管３６を配置する。The central part of the boiler, in particular the water pipe 36, is placed by gradually lifting the boiler and operating it several meters above the ground.
天井の下に配置された楕遺体の外側に配置すべき部材は
