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

Abstract

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

         3 . The construction element according to  claim 2 , wherein each inner channel of the end portions further comprises a coupling element arranged within said each channel and protruding out from each end portion with a second distance, each coupling element comprising a circumferential side wall and a hollow interior, said interior being arranged to receive additional structural elements. 
     
     
         4 . The construction element according to  claim 3 , wherein each coupling element further comprises two interior partition walls, arranged in a cross shape so as to divide the hollow interior into four equal sub-sections. 
     
     
         5 . The construction element according to  claim 1 , wherein an upper surface and a lower surface of the upper and lower plate members respectively comprises a plurality of flange elements, arranged between the distance elements of the end portions, each flange portion having a width corresponding to the width and the height of the distance elements. 
     
     
         6 . The construction element according to  claim 1 , wherein the upper and lower plate members comprises a plurality of via holes, having a predetermined shape. 
     
     
         7 . A module for a prefabrication building system, comprising at least one construction element according to  claim 1 . 
     
     
         8 . A construction comprising at least one construction element according to  claim 1 . 
     
     
         9 . A method for assembly of a construction according to a predetermined scheme, the construction comprising a plurality of structural elements and service installation components, said structural elements comprises; at least one foundation element, at least one room unit, a plurality of facade elements, and a plurality of construction elements for attachment of said structural elements, wherein the number and position of each structural element is determined by the predetermined scheme, said construction element comprising an upper plate member and a lower plate member, having a same width and a same length and extending parallel to each other at a first distance-, wherein the upper and lower plate members are connected to each other along longitudinal sides of said plate members by means of a plurality of intermediate beams, wherein each end portion comprises at least one upper and at least one lower distance element having a width and a height, and being arranged at an upper surface and a lower surface of said end portions respectively, wherein a longitudinally transversal cross section of each end portion forms a cross-shaped circumference, said circumference comprising four right angled abutment surfaces, defined by the plate members and the distance elements, the method comprising the step of:
 a) arranging a number of construction elements at the at least one foundation element by means of coupling each downwards directed distance element of each construction element to the at least one foundation element, defining a first floor level by means of the construction elements.   
     
     
         10 . The method according to  claim 8 , wherein the method further comprises the step of:
 c) arranging a number of room units at the construction elements of the current floor level according to the predetermined scheme, wherein a floor portion of each room unit is coupled to the right angled abutment surfaces of at least two construction elements.   
     
     
         11 . The method according to  claim 9 , further comprising the step of, before the step c):
 b) arranging service installation components for a current floor level according to the predetermined scheme.   
     
     
         12 . The method according to  claim 10 , further comprising the steps of:
 d) arranging a number of construction elements at the room units of the previous floor level according to the predetermined scheme, wherein each construction element is coupled to at least one roof portion of the room units by means of the right angled abutment surfaces, and defining an additional floor level,   e) repeating steps b) to d) so as to reach a total number of floor levels according to the predetermined scheme, and   f) arranging the plurality of facade elements at walls of the room units, which walls are defined as outer walls according to predetermined scheme.
