ALL-WEATHER TEMPORARY ROOF SYSTEM USING STEEL-FRAME STRUCTURE IN NUCLEAR POWER PLANT

摘要

The present invention relates to an all-weather temporary roof system using a steel frame structure in a nuclear power plant to be installed to prevent a construction delay caused by rain during the construction of a nuclear power plant. The present invention provides a new type of temporary roof system management method to lift the roof system by each floor with the construction of each floor of a building with the use of a combination of: an outer climbing frame and an inner sliding frame supported in the steel frame structure of the building to be integrally operated; a hydraulic jack to provide a lifting force; and a stopper to selectively lock the outer climbing frame and the inner sliding frame. Therefore, the all-weather temporary roof system using a steel frame structure in a nuclear power plant shortens a construction period by allowing the construction to be continued against rain; and secures stability and workability as the roof system is lifted by each floor with the construction of each floor.
