Is there a flexible gasket between the column and the connecting body of the glass curtain wall?
Not the elastic gasket is anti-corrosion isolation film to prevent the use of telephone corrosion, then there is a security risk,
As the connection is steel, and the glass curtain wall column steel and aluminum alloy two, so divided into two cases. First, when the column made of aluminum alloy production, the need to add anti-corrosion isolation gasket to prevent electrochemical corrosion; Second, when the column span or because other reasons the use of steel profiles, no need to add this gasket.
"Glass curtain wall engineering technical specifications" JGJ102 is so:
4.3.7 curtain wall connection parts, should take measures to prevent the occurrence of friction noise. The connection between the column and the beam of the structural curtain wall should avoid the rigid contact, the flexible gasket or the gap of 1 ~ 2mm can be set, and the gap is filled. When the hidden wall is connected with the fixed glass assembly, the hook contact surface should be set Flexible gasket.
4.3.8 In addition to stainless steel, the glass curtain wall in contact with different metal materials, should be set up an appropriate insulation pads or anal other anti-corrosion measures
