Abstract
The invention discloses an anti-loosening fastening device which comprises a fastening piece arranged on a pressing plate. An elastic anti-loosening device which prevents the fastening piece from being loosened when a gap is generated between the fastening piece and the pressing plate is arranged at the connection portion of the fastening piece and the pressing plate. 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 a heat insulation piece loses efficacy and disappears, the elastic anti-loosening device deforms 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.
