Example Embodiment
[0037] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0038] Such as Figure 1-11 As shown, the steel arched roof structure of a nuclear power plant of the present invention includes an arched main beam 1, an arched secondary beam unit 2 and a roof structure panel 3. The arched main beam 1 is an arched welding H with straight sections at the end. The section steel is assembled in sections by the first arc-shaped H-shaped steel 1-1, the second arc-shaped H-shaped steel 1-2, and the third arc-shaped H-shaped steel 1-3, wherein the first arc-shaped H-shaped steel 1-1 is the lower end Arc H-shaped steel with vertical sections, two arc-shaped H-shaped steels with vertical sections at the lower end are symmetrically arranged at both ends of the arch main beam 1, and two second arc-shaped H-shaped steels 1-2 are respectively welded to the two first The upper end of the arc-shaped H-shaped steel 1-1, the ...
