Folded Plate Roof Detail

In this way the structural system is capable of carrying loads without the need for additional supporting beams along mutual edges.

Folded plate roof detail. Secure with pop rivets or stitch screws. Some roof conditions such as valleys may require a longer endlap and or a larger flashing to properly drain moisture from the roof. Folded plate structures are assemblies of flat plates or slabs inclined in different directions and joined along their longitudinal edges. 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.

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. Ply sealant and fold the side flaps in and the top flaps down to cap off the ends. 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. Since one of the assumptions made in folded plate roof deaign is that the supporting members diaphragms beama frames etc are infi nltely stiff.

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. In their own. 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.

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. You will then take the huge piece of rubber spread it carefully in place and then take the additional overlap and fold it back on itself. 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. They are transported flat then opened to the desired angle during erection with joints formed and cast in place to unify the structure.

Planes folded plate structures continuous over two spans longi. The first folded plate roofs were used in germany in the 1920 s mainly for very large factory buildings such as coal bunkers. Edge supported folded plates. Mezzanine ceiling structure constructed as a wooden folded structure represents a trapezoidal crease with elements of veneer plywood and horizontal parts of the folded structure are made of solid wood.

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. Factors that influence flashing size shape and endlap requirements.
