Definitions

• This disclosure pertains to the field of civil engineering and more particularly to the construction of building and the like, from modular elements.
• This disclosure improves the situation with a module for a modular building, the module comprising a base, a ceiling and two sidewalls, the base, ceiling and sidewalls delimiting an inner space, each of the base, ceiling and sidewalls having: a layer of a first concrete material facing the inner space; a layer of an insulating material arranged over the layer of first concrete material; and a layer of a second concrete material arranged over the layer of insulating material.
• the insulation is improved.
• the grooves are arranged in at least one zone of the layer of insulating material, and the layer of insulating material has a second thickness comprised between 10 and 20 cm in the at least one zone.
• the grooves in thicker zones of the insulating material, thereby providing a complete layer of insulating material below the grooves.
• the performance of the insulation is reduced.
• the insulation material is a thermal insulator.
• the insulation material is an acoustic insulator.
• the layer of the first concrete material has a thickness that is comprised between 3 and 5 cm.
• the thickness is preferably 4 cm.
• the base, the ceiling and the sidewalls have a depth that is comprised between 2 and 4 meters.
• the depth is preferably 2.40 meters.
• the sidewalls have a height that is comprised between 2.5 meters and 8 meters.
• the height is preferably 3 meters.
• Figure 1 shows an example of two modules 1 which may be used to build a modular building 10.
• the modules 1 are precast and are then brought on a construction site where they are assembled to form a modular building.
• the modules 1 may have a general shape that is stackable in one or more directions X, Y, Z.
• the modules 1 may be of a generally parallelepiped shape.
• each module 1 has a base 2, a ceiling 4 opposite the base 2, and two sidewalls 6, 8.
• the base 2, the ceiling 4 and the sidewalls 6, 8 define an inner space 12 which will constitute the inside of the building.
• the inner space 12 is open at both ends.
• the modular building 10 may also comprise end modules, having a third sidewall closing the inner space at one end.
• Two or more modules 1 may be stacked onto one another to form several floors of a building.
• the modules 1 may comprise a (releasable) mechanical coupling.
• the lower module 1 has a recess 16 on the outer surface of its ceiling and the upper module 1 has a protrusion 18 on the outer surface of its base.
• the recess 16 and the protrusion 18 may engage one another as the upper module 1 is lowered down (e.g., by a crane) onto the lower module 1.
• Other types of complementary shapes may be used.
• the recess 16 may be arranged on the upper module 1 and the protrusion 18 may be arranged on the lower module 1.
• An example of a mechanical coupling is described in figure 5 .
• the module 1 may have a height H that is comprised between 2.5 meters and 8 meters.
• a preferred height is of about 3 meters.
• the module 1 may have a depth D comprised between 2 and 4 meters.
• a preferred depth is of about 2.40 meters.
• the zones 28, 30 may be separated from one another by a central groove 26. Each of the zones 28, 30 may have a square shape. Each of the zones 28, 30 may have a width that is at least 60% of the depth D of the module 1.
• the zones 28, 30 may accommodate an array of grooves 32, 34.
• the array of grooves 32, 34 may comprise grooves 32 extend parallel to a length direction X of the module 1 and grooves 34 which extend parallel to the depth direction Y of the module 1.
• the sidewall 6 goes all the way up.
• the interface between the layers 36A, 36B of second concrete material is vertical.
• the same goes for the interface between the layers 20A, 20B of first concrete material.
• the layers 22A, 22B of insulating material protrude beyond the layers 20A, 20B of first concrete material.
