Description

A flip-slip combined roof structure that can be opened and closed

technical field

The invention relates to an openable and closable flip-sliding combined roof structure.

Background technique

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 hoisting space in the reactor building during construction; it is used to protect the facilities and equipment in the reactor building in rainy and snowy weather.

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.

The brake of the sliding mechanism will lock the brake when it is not running. An anti-collision switch is set at the end of the sliding structure, and when the sliding structure runs to the end of the stroke, it can realize automatic stop operation.

Set up coverings on the flipping and sliding structures, and choose membrane materials for the coverings, and the membrane materials should have sufficient rain, snow and wind resistance capabilities.
