Building lattice work arch truss - has tension struts between tension member and angle-joints in pressure member

摘要

The latticework arch truss (1) for a tall building has a pressure member (2) with angle joints and forming the arch. Tension struts (4) are attached to the angle joints (5) and to one point (12) at each side on the tension member (3). The pressure member can be of wooden sections, butting together at the joints. It also contains slots (6) in which the struts and tension member are secured, typically by nailing. ADVANTAGE - Simple to produce with low cost.
