That is, the aperture ratio of the composite steel shell 83 is 35% to 45%, preferably 35%, 40% or 45%, and most preferably 40%. The hexagonal holes 84 on the composite steel shell 83 multiply increase the anti-pulling force between the composite steel shell 83 and the cement board 81 through the honeycomb arrangement mode, so that all parts of the steel shell composite cement board 8 are stressed uniformly, the weak point of stress damage is avoided to the maximum extent, and the anti-pulling strength of the composite steel shell 83 is greatly increased.
