Height-adjustable stable engineering building scaffold

The utility model discloses a height-adjustable stable type engineering building scaffold which comprises a construction platform, the construction platform can support constructors in the engineering building construction process, four supporting seats are arranged below the construction platform, and sleeves are fixedly connected to the tops of the supporting seats. Through the arrangement of the supporting seat, the first reinforcing rod and the second reinforcing rod, the supporting stability of the whole scaffold can be improved, and through the arrangement of the thread driving mechanism and the linkage mechanism, the supporting height of the construction platform and constructors can be adjusted, so that the constructors with different heights can construct at different heights conveniently, and the construction efficiency is improved. And by means of the lifting arrangement mode of the concentric-square-shaped protection frame, the concentric-square-shaped protection frame can be lifted to shield and
