An axial force can be generated in each chord of the horizontal truss.
In this manner, a supporting bracket for tightening and supporting perforated portions provided at adjacent corners of a plurality of panel materials arranged side by side forming a curtain wall is formed of a string on the convex side with respect to the curtain wall of the horizontal truss. If it is attached to the connection fitting located at the intersection of the material (string material against negative pressure) and the compressed material, the wind pressure load applied to the curtain wall will cause the indoor chord material of the horizontal truss to act on the tensile force, and the curtain by wind pressure Try to suppress wall deformation. Conversely, when the indoor side becomes a positive pressure, the chord on the curtain wall side of the horizontal truss acts as a tension member, and the balance is maintained so that the curtain wall can be restored even if it is deformed.
