Using fallen trees, stringer bridges can be built. Wood laminated by stress, glued, dowels, or nails lumber are good for panel bridges. New lumber and wood scavenged from buildings and railroad ties can be used to build stringer bridges. [3] A licensed engineer can help operators design a safe, appropriate timber bridge.
The traditional slab formwork technique consists of supports out of lumber or young tree trunks, that support rows of stringers assembled roughly 3 to 6 feet or 1 to 2 metres apart, depending on thickness of slab. Between these stringers, joists are positioned roughly 12 inches (30 cm) apart, upon which boards or plywood are placed. The ...
