Temporary wall element

Abstract

A wall element having two sets of columns with panel between the columns so that the columns of the first set and the second set are within each other so that the wall element can be extended and contracted, depending on the room height, in such a way that the wall panels cover the area between columns and form a substantially continuous wall from floor to ceiling.

1 . A wall element for temporary isolation of a building site, the wall element comprising:
 two inner columns, each having a fixed support that is for holding a wall panel and that is a continuous profile extending along the inner column;   a first wall panel arranged between the fixed supports of the inner columns;   two outer columns partially surrounding the two inner columns, each of the outer columns having a fixed support for holding a wall panel; and   a second wall panel arranged between the fixed supports of the outer columns, wherein:   the two inner columns and the two outer columns are configured to be moved relative to each other in the longitudinal direction of the columns so as to adjust the length of the wall element to match a room height of the building site to be isolated,   the wall element further comprises at least one spring that is arranged to exert a force between the two inner columns and the two outer columns to move the columns relative to each other in the longitudinal direction so as to secure the wall element between a floor and a ceiling, and   the first wall panel comprises a door.   
     
     
         2 . The wall element according to  claim 1 , wherein the first wall panel and the second wall panel comprise cellular board. 
     
     
         3 . The wall element according to  claim 2 , wherein the cellular board is a polycarbonate cellular board having a thickness between 6 and 32 millimetres. 
     
     
         4 . The wall element according to  claim 1 , wherein:
 the fixed supports of the inner and the outer columns are arranged to house wall panels of different thicknesses, and   gaskets are arranged between the fixed supports and the wall panels   to secure the wall panels to the fixed supports.   
     
     
         5 . The wall element according to  claim 1 , further comprising a non-slip surface on the outer surfaces that are arranged to be placed against the floor or the ceiling. 
     
     
         6 . The wall element according to  claim 1 , further comprising a guide for partially accommodating a column of a neighbouring wall element so as to obtain a continuous wall from multiple neighbouring wall elements. 
     
     
         7 . The wall element according to  claim 1 , further comprising a felt gasket or a felt seal fixed to the first wall panel or to the second wall panel and arranged to seal a gap between the first wall panel and the second wall panel in a dust proof manner. 
     
     
         8 . The wall element according to  claim 1 , wherein the at least one spring is arranged to be operated with a lever. 
     
     
         9 . The wall element according to  claim 1 , wherein the at least one spring is a pneumatic spring. 
     
     
         10 . The wall element according to  claim 1 , wherein each fixed support of the inner columns extends along substantially the whole length of the inner column. 
     
     
         11 . The wall element according to  claim 1 , wherein the door is hinged to the first wall panel.
