Methods of securing an installed concrete roof |
摘要 |
A method of attaching an installed concrete roof is disclosed. The installed concrete roof consists of rectangular panels positioned along a grid. The concrete panels are supported by metal beams. Smaller metal panels, having a hole in each corner, are positioned over the joints formed by the corners of the rectangular panels. A hole is drilled through the concrete panels and into the supporting beams. A self-tapping screw is positioned through the hole and fixedly attaches the concrete panels to the supporting beams.
