Construction system for a module of a building
The invention proposes a system for constructing a module of a building, including core construction elements ( 1 ) that are surrounded by the surrounding construction elements ( 2 A, 2 B). The core construction elements ( 1 ) each include, in section, a cross including two main arms ( 6 ) of equal length which intersect at mid-length at right angle. Each core construction element ( 1 ) has a plane of symmetry about the axes of the arms. The main arms ( 6 ) of the cross terminate, at the ends thereof, with transverse portions ( 7 ). Each surrounding construction element ( 2 A, 2 B) is composed of four partial surrounding parts ( 2 A, 2 B, 2 A′, 2 B′) of a generally triangular shape which are assembled around a core element ( 1 ). Construction elements forming junction parts ( 4 A, 4 B) allow assembling panels ( 4 A, 4 B) to form a module of a building in the form of a rectangular parallelepiped volume comprising four corners.
