<p><P>PROBLEM TO BE SOLVED: To prevent not only damaging of a floor surface and a ceiling surface at installation of a column between the floor surface and the ceiling surface, but also falling down of a column even when big quake such as an earthquake or excessive impact is added to the column, and to fix and support a column without damaging a floor surface and a ceiling surface, in a column structure of a temporary column that is temporarily fixed and erected between a floor surface and a ceiling surface in a building. <P>SOLUTION: A clearance is formed between a recessed hole of each of an upper support and a lower support and a column in a column structure, whereby a column can be installed in an inclined state. Only the column is moved in each recessed hole by a turning force to further contract a compression spring disposed in the upper support in comparison with the normal time, whereby a larger reaction force can be generated by the compression spring to more firmly fix the column. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
