A support plate for attaching an external wall panel is integrally formed in a substantially T-shape at one end of the mounting plate that is inserted into the gap between the two center columns described above, and the two center columns are attached to the mounting plate. An insertion hole for a bolt extending horizontally is formed, a positioning member is provided on the outer surface of the support plate (the side opposite to the mounting plate), and one side is provided at the upper end of one side edge in the width direction of this positioning member. A locking piece is formed, and another locking piece is formed at the lower end of the other side edge (both locking pieces are formed on a diagonal line of the positioning member) to connect the positioning member and the support plate. A tightening bolt is screwed into the screw hole formed through the hole, an engaging member is attached to the outer end of the tightening bolt, and a spring is elastically interposed between the engaging member and the positioning member. At the same time, the engaging member is rotatable by 90 degrees between the above-mentioned locking pieces, and one end of the above-mentioned mounting plate allows the tightening bolt to protrude toward the indoor side. In the fixing metal fitting formed in this way, a mounting plate is fitted into the gap between the two central pillars, and two holes are inserted into the insertion holes formed in the mounting plate.
It is fixed to the frame by inserting the binding bolt that horizontally binds the middle pillar of the book, and the side end surfaces at the joints of two adjacent outer wall panels installed along the frame are positioning members. The above-described engaging member is rotated within the vertical groove formed on the side end faces of both outer wall panels to engage the engaging member with the side of the vertical groove, and the tightening bolt is tightened. By tightening the engaging members, the side ends of the two adjacent outer wall panels are drawn and fixed to the support plate by the engaging members.

(Function) The fixing bracket is constructed by fitting a mounting plate into the gap between the two center columns, and inserting a binding bolt that horizontally connects the two center columns into the insertion hole formed in the mounting plate. The side end surfaces at the joints of two adjacent exterior wall panels that are fixed to the framework and installed along the framework are respectively applied to the locking pieces of the positioning member, and the side edges formed on the side end surfaces of both exterior wall panels are By rotating the above-mentioned engaging member within the vertical groove to engage the side of the vertical groove, and tightening the tightening bolt, this engaging member can be used to connect two adjacent exterior wall panels.
