TURBINE EXTERNAL COMPARTMENT, FRAME FOR TURBINE EXTERNAL COMPARTMENT, AND METHOD FOR CONSTRUCTING FRAME FOR TURBINE EXTERNAL COMPARTMENT

摘要

The objective is to provide a turbine external compartment with which the flow of steam in the interior of the compartment can be improved and the rigidity of the compartment can be increased with a simple structure, and to provide a frame for a turbine external compartment and a method for constructing a frame for a turbine external compartment. This turbine external compartment is installed in a steel plate concrete structure for which the intervals between multiple steel plates are filled with concrete (13), with a side plate part (3) or an end plate part (4) that forms the lower half of the compartment comprising the steel plates that form the frame.
