PROBLEM TO BE SOLVED: To make a wall structure compact, and to enable accurate position adjustment.SOLUTION: A support structure 10 of a frame material comprises: a connection fitting 11 which has a surface material (intermediate surface 11a) arranged away from a surface of an intermediate mullion 4 opposite to a skeleton 9 and supports the intermediate mullion 4; a bolt member 12 which is provided with a screw part 14 inserted into an opening 15 formed in the surface material of the connection fitting 11 and a head part 13 arranged between the surface of the intermediate mullion 4 opposite to the skeleton 9 and the surface material; and a nut member 16 which is fixed to the skeleton 9 and screwed with the screw part 14. The position of the intermediate mullion 4 can be adjusted in the depth direction in a state of being fixed to the skeleton 9 through the support structure 10 by screwing the bolt member 12 forward and backward relative to the nut member 16. |
