Turnover sliding combined type roofing structure capable of being opened and closed

Abstract

The invention provides a turnover sliding combined type roofing structure capable of being opened and closed. The structure comprises main beams, a main beam bracket, a support, a turnover structure and a sliding structure, wherein the main beams stretch across a building; the main beam bracket stretches across the main beams; the support is used for supporting the main beams; the turnover structure is arranged on the support; and the sliding structure is arranged on the support in a sliding way. A vehicle body sealing plate provided by the invention is simple in structure and high in applicability, and can be directly arranged on a steel safe shell cylinder body. Large-area opening or closing can be realized through automation, the requirements on building lighting, rain and snow resistance and wind resistance can be met, the lifting operation requirement of a reactor building can be met, and the structure can be conveniently mounted and dismounted for reuse.

Description

technical field [0001] The invention relates to an openable and closable flip-sliding combined roof structure. Background technique [0002] The third-generation advanced nuclear power technology of AP1000 adopts an open-top construction method, that is, equipment and bulk materials are hoisted sequentially before the structural roofing of the reactor building is completed. On the one hand, the open-top construction method is conducive to the parallel development of civil engineering and installation work, shortening the construction period; but on the other hand, the open-top construction makes the reactor building directly exposed to the atmospheric environment during the construction and installation period, and is more vulnerable to rain, snow and typhoon weather. Therefore, a temporary roof structure that can be opened and closed is required. This roof structure can be automatically opened and closed according to needs, so as to provide the required lighting and hoisti...

AI Technical Summary

Problems solved by technology

The common building roof structure is generally installed on relatively wide and thick concrete supports. Therefore, the general building roof structure cannot be installed on the thin-walled steel cylinder of the containment vessel of the reactor building. The type roof structure is simple and light, and can be directly installed on the steel containment shell
