Aerated concrete external wallboard swing joint

The utility model discloses an aerated concrete external wallboard swing joint which comprises an embedded part and an angle steel connecting part. The embedded part comprises two connecting steel plates and four anchor bars, the connecting steel plates are welded to transversely-distributed bars of an aerated concrete plate, and the two connecting steel plates and an aerated concrete steel reinforcement frame form a whole through the four anchor bars. The embedded part is connected with the angle steel connecting part through four bolts, and the angel steel connecting part is provided with one long hole groove and four round holes. In addition, a triangular reinforcing plate is welded to the folded corner position of angle steel, and the long hole groove can be connected with a body frame beam through a bolt. The aerated concrete external wallboard swing joint is based on the idea of a swing joint, the mode of combining the embedded part and a sliding joint is adopted, an aerated concrete external wallboard can freely slide along with interlayer deformation during an earthquake, therefore, large earthquake force can be prevented from being transmitted to an aerated concrete wall, the anti-seismic property is good, construction is convenient, and the aerated concrete external wallboard swing joint is suitable for being popularized in industrialized residences.
