建造を行うようにしたボイラーの建設方法（通称ビラ−
ミツド工法）に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a boiler construction method (commonly known as a boiler construction method) in which the steel frame is constructed while incorporating ducts, piping, and equipment installed in the steel frame into the steel frame. −
This is related to the Mitsud method.

型ブロック化はできず、小さい部材として取込み組立て
据付けていたので、高床作業が多く、安全性も悪く且つ
据付は工期が長期にわたるという欠点があった。Conventionally, when constructing a boiler, after the steel frame had been erected, the pipes, piping, and equipment were pulled into the steel frame using wires, etc., and installed in conjunction with the installation of the pressure-resistant parts of the boiler body. However, in such conventional construction method,
The installation of the side pressure section of the boiler main body and the installation of various parts such as ducts, piping, equipment, etc. were complicated, and when pulling in, it was not possible to make large blocks, but small parts were brought in, assembled and installed, so work on raised floors was difficult. In many cases, the drawbacks were that safety was poor and installation took a long time.
本発明は上述の観点に鑑み、ボイラーの建設を短期間で
行い得るようにしたボイラーの建設方法を提供すること
を目的としてなしたものである。The present invention has been made in view of the above-mentioned viewpoints, and an object of the present invention is to provide a boiler construction method that enables the boiler to be constructed in a short period of time.
本発明によれば、ボイラー鉄骨の建方に並行してダクト
類、配管類、機器類等の部材を鉄骨の部材とみなして鉄
骨の建方に合せながら、鉄骨内に取り込み、ボイラー鉄
骨を建造している。According to the present invention, in parallel with the erection of the boiler steel frame, members such as ducts, piping, equipment, etc. are regarded as steel frame members and incorporated into the steel frame in accordance with the erection of the steel frame, and the boiler steel frame is constructed. are doing.
従って、鉄骨建方の完了時に鉄骨内への上記部材の取り
込みは完了するので、ボイラ一本体の据付は工事と輻輳
することもなく、大幅な工期の短縮が可能となる。又、
上記部材を、工場又は地上で大型ブロック化し、取込む
ことが可能となるので、高床作業も減り安不性がその分
だけよくなる。Therefore, since the above-mentioned members are completely inserted into the steel frame when the steel frame erection is completed, the installation of the boiler main body is not complicated with the construction work, and the construction period can be significantly shortened. or,
Since the above-mentioned members can be made into large blocks in a factory or on the ground and then brought in, the need for work on elevated floors is reduced and safety is improved accordingly.
以下、本発明の実施例を図面を参照しつつ説明する。Embodiments of the present invention will be described below with reference to the drawings.

は工程の短縮が図れる。Next, lift the duct (7) of a predetermined length placed on the ground L from the truck crane (4) and insert the duct into the steel pipe from the side a few meters away from the beam (2). Temporarily place the duct l-+71 on the required floor surface of the ironworks that has been installed, and then lift the beam (2) with the hanger (5) attached from the ground using the truck crane (4). 1), or attach it to the front side of the hanger (5) if necessary.
) with the small beam (3) attached to the truck crane (4)
After lifting it up and installing it between the beams (2+ +21), the truck crane (4) lifts up the duct (7), which is temporarily placed on the required floor surface inside the steel frame, again and attaches it to the beam (2) and small beam (3). Hanger (5) is hung from an O-shaped set.Therefore, the hanger itself can be attached to the beam on the ground, eliminating the need for a scaffolding like in the past, and the duct can be installed using steel frame construction. Since lifting can be carried out using heavy equipment such as a commercial truck crane, it is now possible to install ducts in three-dimensional blocks at a factory or on the ground, instead of the conventional method of creating three-dimensional structures after taking in the takt time of each surface. and the installation process can be shortened.
