Abstract: A multi-purpose part (32), comprising: a frusto-conical projection (322?) in a lower end INF; a frusto-conical housing (322) in an upper end SUP, arranged to match the frusto-conical housing (322?); a falling mortar pipe (326) extending from the upper end SUP to the lower end INF of the pillar and having, at the lower end (INF), a portion (326?) which curves from a downward vertical plane toward a front face of the frusto-conical projection (322?) for the introduction of mortar; a rising mortar pipe (327) extending from the lower end INF to the upper end SUP of the pillar and having, at the lower end INF, a portion (327?) which is bent from a horizontal plane toward an upward vertical plane so that the mortar introduced rises until a cavity defined by the mortar pipes (326, 327), the frusto-conical housing (322) and the frusto-conical projection (322?) is filled.

Abstract: The invention relates to a dwelling module, a roof module, a balcony module, a facade module, a building and a lifting tool for a modular construction system used to form a building from the aforementioned modules. The dwelling module (3) includes a floor (31), a roof (34T) and pillars between the floor (31) and the roof (34T). The pillars contain an embedded multi-purpose part (32) which is used to stack one module on top of another. The roof module is positioned on top of the building, while the balcony module (359) and the facade module (310) can be positioned peripherally to the building. The lifting tool is used to transport and install the dwelling module (3) at the desired site in order to complete a building.
