Folded plate roof detail.

Folded plate structures are assemblies of flat plates or slabs inclined in different directions and joined along their longitudinal edges. Definition folded plates are assemblies of flat plates rigidly connected together along their edges in such a way that the structural system capable of carrying loads without the need for additional supporting beams along mutual edges. The goal is to cut a piece that is big enough to cover the roof as well as leave an additional 9 inches around the entire roof. Some roof conditions such as valleys may require a longer endlap and or a larger flashing to properly drain moisture from the roof.

Secure with pop rivets or stitch screws. Since one of the assumptions made in folded plate roof deaign is that the supporting members diaphragms beama frames etc are infi nltely stiff. Factors that influence flashing size shape and endlap requirements. Ply sealant and fold the side flaps in and the top flaps down to cap off the ends.

The usual upturned edge plate can be eliminated and the roof structure can be made to appear very thin if the edge plate is replaced by a series of columns. The construction method and design rationale as developed in china are be. In this way the structural system is capable of carrying loads without the need for additional supporting beams along mutual edges. Precast prestressed folded plate roof elements are cast flat with hinges between panels.

Folded plate roofs are roofing systems chosen for their high weight bearing capacity and their durability. They can be best described as assemblies that consist of flat slabs or plates that are inclined in different directions and are joined along their edges at the top. The first folded plate roofs were used in germany in the 1920 s mainly for very large factory buildings such as coal bunkers. They are transported flat then opened to the desired angle during erection with joints formed and cast in place to unify the structure.

The slab between columns must be designed as a beam and it may be convenient to extend the main roof slab as a cantilever canopy. The center to center longitudinal span is forty 40 feet and in the transverse direction the columns are spaced at ten 10 feet on centers. This technique originated in germany in the 1920s and became popular in russia and the united states during the 1930s to construct roofs for industrial warehouses and public buildings. It consists of a four bay folded plate structure carried by ten 10 concrete columns originally intended to cover a parking space for eight standard size vehicles with access from both ends.
