Roof construction for buildings, especially industrial buildings with large widths, comprises bottom and top booms in the form of I-shaped supports with two boom flanges, and node elements with two flat node flange plates

摘要

Roof construction (1) comprises a supporting framework (2) consisting of node elements (5, 8), top booms (7), bottom booms (4) and intermediate bars (10). The bottom and top booms are I-shaped supports with two boom flanges that are arranged a distance apart and parallel to each other and/or parallel to the boom planes (3, 6). The node elements each have two flat node flange plates that are arranged a distance apart and parallel to each other and to the booms. The bottom and top booms are fixed, especially screwed, to the node flange plates so that the bottom or top booms adjoining the node element rest with the end region of the first boom flange in a flat connection with the first node flange plate and with the end region of the second boom flange in a flat connection with the second node flange plate.
