Document Type and Number:
Japanese Patent JP6856984
Kind Code:
B2
Abstract:
The invention relates to a fire resistant wall structure (1), comprising a first wall element (2) and a second wall element (3). Both wall elements comprise a surface plate (4), which is provided at its first edge (41) and at its second edge (42) opposite to the first edge with bends for joining the wall elements to each other. In order to provide a light and robust structure, the first wall element has its first edge (41) provided with a first set of bends (10') having a first bend (51') which is fashioned at a right angle relative to the surface plate and from which is established a second bend (52') which is in parallel direction with the surface plate and from which is established a third bend (53') made at a right angle against the surface plate for constructing a closed box type structure. The second wall element has its second edge (42) provided with a first bend (61') which is fashioned at a right angle relative to the surface plate and from which is established a second bend (62') in parallel direction with the surface plate for constructing an open recess at an edge of the wall element. In order to secure the wall elements to each other, the first set of bends having a closed box type structure is adapted to be fitted to the second set of bends which establishes an open recess.
