Summary
| Description |
English: An angle block design for a Howe truss bridge. The angle block is made of solid cast iron. A hole is drilled through the top to provide access for the vertical beam. The lower portion of the beam is threaded so that a nut (sometimes a nut and iron plate) can be screwed to the beam to hold it in place. Lugs (seats) accept the diagonals and diagonal counter-braces. These are held in place partially by a hole drilled in the lug and the diagonal and diagonal counter-braces, though which a bolt is threaded and screwed into place. The upper and lower screws on the vertical beams are then tightened, putting the diagonals and diagonal counter-braces into compression and holding them in place against the lugs and angle block. |
