Design - "Hextroo" a multi-purpose mold

HEX IS MORE Federica Onorato Giuseppe D’Alessandro Lucas Napolitano

PROJECT REQUIREMENTS

_modularity _multifunctionality _one mold to cast all the pieces _extruding form _easy identification of the set _indoors and outdoors uses

CONCEPT

The project revolves around a perfect hexagon.

The geometry of the hexagon offers different lengths, heights and inclinations, letting us explore several forms, yet correlated.

One piece never intersects another, though we can create new pieces juxtaposing two elements casted separately.

FORM STUDY table

Ideal for private spaces can’t take high loads

Different possible openings, giving the idea of a light object

Closed model, stronger. Ideal for public uses (parks, squares, information point)

FORCES STUDY table

all the corners are reinforced, so all the configurations are possible 4kN is a variable force considering a public use

MOLD base

Two removable parts are assembled with the base, creating the space for the mold walls

Space for the mold walls

MOLD external walls

The two modules are joined with pins

The external walls are assembled two by two, creating two simetrical modules

Final form of the external mold

Corner plates reinforce the joints and guarantee no leaks

MOLD internal walls

Pre-made corners guarantee the 7cm thickness in the fragile points

MOLD base internal walls external walls

Steel corner plates reinforce the joints also in the horizontal corners

Casting area, 7cm thick in the thickest parts.
