.The structure not lining up for roof system and flooring deformation joint, article two, the curtain wall upper and lower side between deformation joint be take respectively different structure unit as bearing, if adopt can not emission surface in the bearing pin of constraint hinged, when agent structure unit is out of shape round about due to geological process, the relative storey displacement angle of their plane internal deformation angle agent structure is
.Due to
, curtain wall plane internal deformation ability is difficult to meet the demands, and very easily causes crimp in curtain wall face, and then causes glue-line disengagement or face glass and point-supporting bearing collision explosion between face glass and frame.
