Curtain wall works keel wall thickness is the smallest number
Metal and stone curtain wall:
Vertical keel: column section of the main force part of the thickness of the aluminum section of the main part of the thickness of the thickness of the part should not be less than 3mm, threaded connection when the threaded connection part of the thickness of the cross section should not be less than the nominal diameter of the screw; The thickness of the main part of the section should not be less than 3.5mm.
The thickness of the main part of the section of the aluminum alloy section shall not be less than 2.5mm when the span of the beam is less than 1.2m. When the span of the beam is more than 1.2m, the section is mainly affected by the force The thickness of the site should not be less than 3mm. The cross section thickness of the screw connection shall not be less than the nominal diameter of the screw; the thickness of the main section of the steel section shall not be less than 3.5mm.
Glass curtain wall:
Vertical keel: aluminum section of the opening part of the thickness should not be less than 3.0mm, the thickness of the closed part should not be less than 2.5mm; profile hole between the wall and the screw directly when the threaded connection. Its local thickness should not be less than the nominal diameter of the screw; steel section of the main part of the thickness of the thickness should not be less than 3.0mm.
The thickness of the main part of the section of the aluminum alloy section shall not be less than 2.0mm when the span of the beam is less than 1.2m. When the span of the beam is more than 1.2m, the section is mainly affected by the force of the cross section. The thickness of the part should not be less than 2.5mm. The thickness of the section should not be less than the nominal diameter of the screw when the thread between the hole and the screw is directly connected with the screw. The thickness of the main section of the steel section shall not be less than 2.5mm.
Construction, the steel keel is generally not less than 4mm, because less than 4mm when welding easy to wear.
