Abstract
The invention discloses an anti-loosening fastening device which comprises a fastening piece. A heat insulation piece is arranged between the fastening piece and a pressing plate for being provided with the fastening piece in a sleeved mode. An elastic clamping ring which contracts and fills a gap between the fastening piece and the pressing plate after the heat insulation piece loses efficacy and disappears is arranged on the outer periphery of the heat insulation piece. The anti-loosening fastening device has the advantages of being simple in structure, convenient to mount and capable of improving fastening intensity effectively. The invention further discloses a curtain wall which comprises the pressing plate, a keel and a curtain wall plate. The curtain wall plate is in fastening connection with the pressing plate and the keel through the anti-loosening fastening device respectively. The curtain wall plate is clamped between the pressing plate and the keel. When the heat insulation piece loses efficacy and disappears, the elastic clamping spring contracts and fills the gap between the fastening piece and the pressing plate. The curtain wall has the advantages of being simple in structure, convenient to mount and capable of improving fastening intensity effectively.
