The LEWLEX project covered a complete set of workshop drawings for external steel stairs intended for an industrial installation. The documentation was structured into 9 A3 sheets and resolves the whole...
The primary load-bearing system consists of two stair flights and two landings: one intermediate and one upper. The structure is built around C160×65×7 mm stringers identified as B1–B11 and support posts...
The foundation package defines concrete pad footings below each support, with indicative sizes of 400×400×400/600/800 mm in C25/30 concrete. Beneath every leg the drawings specify a 200×200×10 mm base...
Connections between the stringers are resolved through a set of steel joints X, V and Z, together with mounting plates M and N, all made from 10 mm S235JR steel plate. Ø12 mm holes are prepared for M10×50...
