Protective structure for board partitions
A seismic protective structure ( 100 ) for forming part of a board partition ( 190 ) and for limiting damage to the board partition ( 190 ) when a given level of seismic stress is appearing is described. The seismic protective structure ( 100 ) comprises at least one board ( 101 ) and support elements ( 102, 103 ) for positioning the board adjacent a neighboring wall and linking the board to the remainder of the board partition wall. The seismic protective structure ( 100 ) is adapted for, when a given level of seismic stress is appearing, intentionally causing damage of the at least one board ( 101 ) thereby releasing pressure from the remainder of the board partition ( 190 ).
1. A seismic protective structure ( 100 ) for forming part of a board partition ( 190 ), the seismic protective structure ( 100 ) comprising:
at least one board ( 101 ),
a first support element ( 102 ) connected to the at least one board ( 101 ) and to an adjacent wall ( 105 ) to the board partition ( 190 ),
a track element ( 104 ) connectable to the adjacent wall ( 105 ) the track element ( 104 ) being positioned for guiding and moveably positioning the first support element ( 102 ) therein,
at least one wedge ( 201 ) shaped and positioned for, upon a given relative movement of the track element ( 104 ) and the first support element ( 102 ), separating the board ( 101 ) from the track element ( 104 ), and
a second support element ( 103 ) linking the at least one board ( 101 ) with a remainder of the board partition ( 190 ),
wherein the board partition ( 190 ) is severable from the adjacent wall ( 105 ) upon a given level of seismic stress, and releasing stress from the remainder of the board partition ( 190 ).
2. A seismic protective structure ( 100 ) according to claim 1 , wherein the at least one wedge ( 201 ) is shaped and positioned for, upon the given relative movement of the track element ( 104 ) and the first support element ( 102 ), shifting between the first support element ( 102 ) and the board ( 101 ) for separating the board ( 101 ) from the first support element ( 102 ).
3. A seismic protective structure according to claim 2 , wherein the track element ( 104 ) is configured in shape with a protrusion for spacing the board ( 101 ) and the first support element ( 102 ) with a gap for, upon the given relative movement of the track element ( 104 ) and the first support element ( 102 ), introducing the wedge ( 201 ) between the board ( 101 ) and the first support element ( 102 ).
4. A seismic protective structure according to claim 1 , wherein the first support element ( 102 ) comprises a weak portion for breaking of the first support element ( 102 ) upon the given level of seismic stress.
5. A seismic protective structure ( 100 ) according to claim 4 , wherein the first support element ( 102 ) comprises two, substantially symmetric sub-elements glued to each other, and the weak portion corresponds with a gluing zone where the sub-elements are glued to each other.
6. A seismic protective structure ( 100 ) according to claim 1 , wherein the at least one wedge ( 201 ), the first support element ( 102 ) and the track element ( 104 ) are integrated in a single piece.
7. A seismic protective structure ( 100 ) according to claim 1 , wherein the at least one board ( 101 ) comprises a weaker portion such that, upon the given level of seismic stress on the board partition ( 190 ), the board ( 101 ) will break at the weaker portion.
8. A seismic protective structure ( 100 ) according to claim 1 , wherein the board ( 101 ) is connected through a rotating suspension ( 1901 ), with the second support element ( 103 ) or a further board of the board partition ( 190 ).
9. A seismic protective structure ( 100 ) according to claim 1 , wherein the board is a gypsum board ( 101 ).
10. A seismic protective structure ( 100 ) according to claim 1 , wherein the first and second support elements ( 102 , 103 ) are substantially parallel.
11. A seismic protective structure ( 100 ) according to claim 10 , wherein said first and said second support elements ( 102 , 103 ) are substantially vertically mounted.
12. A method for restoring the board partition ( 190 ) after an earthquake, the board partition ( 190 ) comprising a seismic protective structure ( 100 ) according to claim 1 , the method comprising replacing the at least one board ( 101 ) and the first support element ( 102 ) for restoring the board partition ( 190 ).
13. A seismic protective structure ( 100 ) according to claim 1 , wherein the at least one wedge ( 201 ) is configured to break the first support element ( 102 ) into two parts upon the given level of seismic stress.
