The utility model discloses a
keel structure for an architectural decoration
curtain wall, which is characterized in that moving grooves are formed in the front surface and the rear surface of a first
keel, connecting components are slidably connected in the moving grooves, and the connecting components are in a rectangular-
ambulatory-plane shape; the connecting
assembly is composed of a second mounting groove, a connecting block, a first drainage hole, a second drainage hole and a threaded nail, the first mounting groove is formed in the first
keel, the first keel is made of cold rolled steel, the second keel and the third keel are made of aluminum
alloy, the overall rigidity is improved, stress is dispersed, the decorative wall curtain is prevented from deforming or
cracking, and the service life of the decorative wall curtain is prolonged. Materials with different thicknesses and different shapes are adopted, the cost is saved, the purpose of optimizing the material
utilization rate is achieved, the effects of rapid installation and screw use reduction are facilitated, meanwhile, the functions of ventilation, drainage and the like between keels can be achieved, and therefore the overall service life of the
keel structure is prolonged.
