Building Element and a Building Structure Comprising the Building Element

Abstract

The invention relates to a building element for a building structure such as a floor structure, comprising a member ( 10, 21, 40 ), said member having a planar portion ( 10 d, 40 d ), and at least a part ( 11, 12, 43, 44, 45 ) of a mould ( 111 ) provided at an edge ( 10 a, 21 a, 40 a ) of the member ( 10, 21, 40 ).

1 . A building element for a building structure, the building element comprising: a member having a planar portion; and at least a part of a mould provided at an edge of the member. 
   
   
       2 . A building element according to  claim 1 , wherein the member comprises high performance concrete. 
   
   
       3 . A building element according to  claim 2 , wherein said concrete has a water-cement ratio equal to or lower than 0.039. 
   
   
       4 . A building element according to  claim 2 , wherein said concrete comprises ballast material including an open pore structure material for receiving during heating water vapour from water in the concrete. 
   
   
       5 . A building element according to  claim 4 , wherein said ballast material is non-combustible material. 
   
   
       6 . A building element according to  claim 1 , wherein the member includes reinforcement means. 
   
   
       7 . A building element according to  claim 6 , wherein the reinforcement means includes specially formed fibres mixed within the member. 
   
   
       8 . A building element according to  claim 6 , wherein the reinforcement means includes local reinforcement units protruding out of the planar portion at the edge. 
   
   
       9 . A building element according to  claim 1 , wherein the member further comprises includes at least one beam portion extending from the plane of said planar portion. 
   
   
       10 . A building element according to  claim 9 , wherein the at least one beam portion extends laterally essentially perpendicular to the planar portion. 
   
   
       11 . A building element according to  claim 9 , wherein the at least one beam portion is provided at a region between the edges of the planar portion, said beam portion including an intermediate beam portion. 
   
   
       12 . A building element according to  claim 9 , wherein the at least one beam portion is provided at, at least one of the edges of the planar portion. 
   
   
       13 . A building element according to  claim 9 , wherein the at least one beam portion includes the at least a part of the mould. 
   
   
       14 . A building element according to  claim 6 , wherein the reinforcement means comprises at least one reinforcement member, and wherein a part of the at least one reinforcement member protrudes out of the planar portion at the edge at which the part of a mould is fixed. 
   
   
       15 . A building element according to  claim 1 , wherein the edge at which the part of the mould is provided forms at least partly an additional part of the mould. 
   
   
       16 . A building element according to  claim 1 , wherein the part of the mould has an elongate shape. 
   
   
       17 . A building element according to  claim 1 , wherein the member has an elongate shape, and the part of the mould extends alongside the planar portion. 
   
   
       18 . A building element according to  claim 1 , wherein the part of the mould extends at least partly out of the plane of the planar portion. 
   
   
       19 . A building element according to  claim 14 , wherein at least one reinforcement member is located, in relation to the part of the mould, in a position which it is intended to assume after a casting process involving the part of the mould. 
   
   
       20 . A building element according to  claim 1 , wherein the building structure has an essentially horizontal extension. 
   
   
       21 . A building element according to  claim 20 , wherein, in an intended final position of the building element, the part of the mould extends laterally downwards from the planar portion. 
   
   
       22 . A building element according to  claim 1 , further comprising an additional member, the members oriented substantially parallel to each other and located at a distance from each other in a direction perpendicular to their planes, the part of the mould extending laterally from one of the members to the other. 
   
   
       23 . A building structure comprising a building element, the building element including a member having a planar portion and at least a part of a mould provided at an edge of the member.
