INSTALLATION STRUCTURE FOR ROOF STEEL FRAME STRUCTURE WITHOUT PURLIN

摘要

The present invention relates to an installation structure for a roof steel structure from which a purlin is excluded, and more specifically, to an installation structure for a roof steel structure from which a purlin is excluded, wherein the installation structure comprises a large beam (20) and roof sandwich panels (40) installed on the upper side thereof. According to the present invention, plate-shaped reinforcing plates (90) are installed between the large beam (20) and the roof sandwich panels (40), or H-sectional steels (91) are installed between the large beam (20) and the roof sandwich panels (40) so that: construction materials and construction periods can be reduced; energy efficiency can be improved by reducing an insulation area as much as the width of the purlin; construction costs for exterior materials can be reduced; and the constructional convenience and robustness of the roof steel structure can be improved even if the purlin, or the purlin and a small beam are excluded.
