COMPOUND GIRDER FORMING A RIGID CONNECTION FOR PREFABRICATED CEILING PANELS

摘要

TITLE OF THE INVENTION: COMPOUND GIRDER FORMING A RIGID CONNECTION FOR PREFABRICATED OF CEILING PANELS compound girder of an on-site assembly type is assembled to include components which rigidly interconnect two or more prefabricated ceiling panels (3a, 3b) in a bending stiff manner. The compound girder includes for each ceiling panel (3a, 3b) at least one web section (1a, 1b) and an upper chord section (2a, 2b). The girder further includes a continuous length lower chord (4). The lower chord (4) takes up the tension and shearing loads. The individual web sections (la, lb) are secured to the lower chord (4) by screw connections which prevent a sliding displacement between the connected elements relative to each other. 1287/Canada - 1
