Problems solved by technology

If the method of thickening the thickness of the roof panel 1 is adopted, although it can also resist the upward throwing force, it will also increase the self-weight of the roof panel 1 and increase the burden on the lower supporting structure

Embodiment 1

[0025] This embodiment provides an anti-throwing building structure for a roof of a nuclear power plant, including: a roof slab, a main beam disposed below the roof slab, and an anti-beam disposed above the roof slab, and the anti-beam is used to bear the upward throwing force of the roof slab.

[0026] The anti-throwing building structure of the roof of the nuclear power plant in this embodiment bears the upward throwing force of the roof slab through the anti-beam arranged above the roof slab. Compared with the method of simply increasing the thickness of the roof slab in the prior art, in this embodiment Under the premise of ensuring the design requirements, the method reduces the weight of the roof panel, saves manpower and material costs, and shortens the construction period. The anti-throwing building structure of the roof of the nuclear power plant in this embodiment not only meets the structural design requirements, but also is simple and reasonable in structural layout...

Embodiment 2

[0028] Such as Figure 2-4 As shown, the present embodiment provides an anti-throwing building structure for the roof of a nuclear power plant, including: a roof panel 1, a main beam 2 arranged below the roof panel 1, an anti-beam 5 arranged above the roof panel 1, and the anti-beam 5 is used To bear the upward throwing force of the roof panel 1.

[0029] Preferably, there are at least two main beams 2 and at least two reverse beams 5 . Specifically, there are more than two main beams 2 in this embodiment, and more than two reverse beams 5 .

[0030] It should be noted that the anti-beams 5 in this embodiment are arranged in parallel.

[0031] It should be noted that the anti-beam 5 in this embodiment is arranged corresponding to the main beam 2 , and the orthographic projection of the main beam 2 on the roof slab 1 overlaps with the orthographic projection of the anti-beam 5 on the roof slab 1 .

[0032] The spacing between the anti-beams 5 is arranged according to the spa...

Embodiment 3

[0042] Such as Figure 5 As shown, this embodiment provides a nuclear power plant roof anti-throwing building structure, and the difference between the nuclear power plant roof anti-throwing building structure in Embodiment 2 is: the nuclear power plant roof anti-throwing building structure in this embodiment, It also includes: a drainage board 11 arranged above the anti-beam 5 , and the drainage board 11 covers the anti-beam 5 , the roof panel 1 and the wall 4 .

[0043] Specifically, the roof panel 1 in this embodiment is a non-open-air roof panel, the drainage board 11 is a light drainage board, and the light drainage board is a profiled steel plate.

Abstract

The invention discloses a nuclear power plant roof anti-throwing building structure which comprises a roof panel, a front beam arranged below the roof panel and a reverse beam arranged above the roofpanel, and the reverse beam is used for bearing the upward throwing force of the roof panel. In the anti-throwing building structure for the nuclear power plant roof, the reverse beam arranged above the roof panel bears the upward throwing force of the roof panel, and compared with a method of simply increasing the thickness of a roof panel in the prior art, the method has the advantages that on the premise that the design requirement is guaranteed, the dead weight of the roof panel is reduced, the labor cost and the material cost are saved, and meanwhile, the construction period is shortened.The anti-throwing building structure for the nuclear power plant roof meets the structural design requirement, is simple and reasonable in structural arrangement, and facilitates on-site construction.

Description

technical field [0001] The invention belongs to the technical field of nuclear engineering, and in particular relates to an anti-throwing building structure for a roof of a nuclear power plant. Background technique [0002] Such as figure 1 As shown, at present, many large roof panels 1 of nuclear power plants are supported by steel beams, which can effectively reduce the thickness of the roof panel 1 and facilitate construction. Under the earthquake load, the roof panel 1 of the nuclear power plant generates relatively large downward and upward loads. In the architectural structure of the roof of a nuclear power plant, the roof panel 1 is set on the wall 4, and the downward load of the roof panel 1 can be borne by the main beam 2 (steel beam) below the roof panel 1, but the upward load of the roof panel 1, that is, causes The force 3 thrown on the roof panel 1 has no corresponding supporting structure. In civil buildings, this upward throwing force is very small and can ...
