The present invention relates to an assembled steel pipe framework for a power plant, and more particularly, to a power plant that can assemble efficiently for assembling and repairing a boiler in a large workplace such as a thermal power plant or a nuclear power plant, It is about the assembled steel pipe framework for equipment

Generally, steel frame scaffolding pipes are used as scaffolding frameworks that must be prepared for maintenance and construction work of all facilities.

Tightening the pipe while clamping the pipe with the clamp requires a long working time, and it is not possible to work safely without a specialist.

In particular, in the case of appliances hanging in the sky, such as power generation facilities, heavy machinery needs to be stacked vertically without any side support from the floor to the high place.

Therefore, we are making efforts to secure the safety of assembly framework required for all industries as well as thermal / nuclear power generation.

In addition, when a scaffold frame with a high height is installed solely on the ground and can not be linked to existing structures, the safety is gradually lowered according to the height, and in the case of working heavy articles on the scaffold, Not only seriously undermined safety, but also caused a collapse of the scaffolding framework, resulting in a high risk of safety accidents.

In order to solve this problem, there is a prior art patent registration No. 10-1216558. However, since it is possible to maintain the level of each layer accurately to improve the safety of the frame, it takes a long time for assembly and installation, There is a risk of conduction even if it can be maintained accurately.

Accordingly, it is a main object of the present invention to provide an assembled steel pipe framework for a power plant, which can be assembled safely and quickly while lifting each floor when assembling a framework for maintenance and maintenance of a boiler for power generation.

It is another object of the present invention to provide an assembled steel pipe framework for a power generation facility that can be safely supported by a wire of a frame.

It is another object of the present invention to provide an assembled steel pipe framework for a power generation facility which allows an operator to safely and conveniently move the elevation up and down on each footplate during use of the frame to expand the work space.

In order to achieve the above-mentioned object, the present invention provides an assembled steel pipe framework for a power plant, comprising: an upper lift plate for forming an operation position of an operator, A supporting steel pipe vertically assembled and gradually assembled to the operating hole of the upper and lower lifting plate, and a supporting steel pipe vertically connected to the supporting steel pipe, A control port for sequentially supporting and releasing the upper and lower lift plates, and a descending and descending portion for sequentially elevating or lowering the upper lift plate and the lower lift plate by interconnecting the upper and lower lift plates with the bolts. The basic features of

Therefore, the assembled steel pipe framework for a power plant of the present invention is mainly used for maintenance and maintenance of a boiler for power generation and the like. While the lower lift plate is supported, the bolts are rotated to raise the upper lift plate, When the supporting bolt is rotated backward, the lower lifting plate is lifted and brought into close contact with the upper lifting plate. At this time, the supporting state of the upper lifting plate is released and the lower lifting plate is supported and initialized and repeated It is possible to sequentially and precisely install the scaffold frame to a desired height and at the same time to secure a wide working space while raising and lowering the uppermost elevating plate at the uppermost side as well as firmly supporting the scaffold frame and controlling the wire rope Sphere and floor or structure Thereby reducing the incidence of safety accidents drastically.
