Technical Field
The invention belongs to the technical field of nuclear engineering, and particularly relates to a nuclear power plant roof throwing-proof building structure.
Background
As shown in fig. 1, the large roof panel 1 of the nuclear power plant is supported by steel beams, so that the thickness of the roof panel 1 can be effectively reduced, and the construction is facilitated. The nuclear power plant roof panel 1 generates large downward and upward loads under earthquake loads. In the building structure of the nuclear power plant roof, a roof panel 1 is arranged on a wall body 4, the downward load of the roof panel 1 can be borne by a front beam 2 (steel beam) below the roof panel 1, but the upward load of the roof panel 1, namely the upward force 3 of the roof panel 1, does not have a corresponding supporting structure. In civil buildings, this upward force is small and generally negligible. However, the seismic loads considered by nuclear power plants can be large and the effect of such upward thrust is not negligible. If the method of thickening the thickness of the roof panel 1 is adopted, although the upward throwing force can be resisted, the self weight of the roof panel 1 is increased, and the burden is added to the supporting structure at the lower part.
