Construction element， a module and a construction comprising such an element and method of assembly of such a construction

The invention relates to a construction element (1) for attachment of structural elements. The element (1) comprises an upper plate member (3) and a lower plate member (5)， having a same width (7) and a same length (9) and extending between two end portions (11)， parallel to each other at a first distance (13). The upper and lower plate members (3， 5) are connected to each other along longitudinal sides (15) of said plate members (3， 5) by means of a plurality of intermediate beams (17). Each end portion (11) further comprises at least one upper and at least one lower distance element (19) having a width (21) and a height (23)， and being arranged at an upper surface (25) and a lower surface (27) of said end portions (11) respectively. A longitudinally transversal cross section of each end portion (11) forms a cross-shaped circumference， said circumference comprising four right angled abutment surfaces (29)， defined by the plate members (3， 5) and the distance elements (19). The invention also relates to a module (85) and a construction (67) comprising such a construction element (1) and a method of assembly of such a construction (67).
