The invention relates to an architectural engineering aerial work platform which comprises multiple building row hedges, supporting steel tubes and building row hedge connecting pieces. The building row hedges are manufactured through plastic steel, arranged on the supporting steel tubes and provided with connecting holes, and the building row hedges are connected in a clamped mode through the connecting holes. The building row hedges are manufactured through the plastic steel, quality is excellent, the service life is long, practical performance is high, the weight of the building row hedges accounts for two thirds that of an original bamboo hedge, the building row hedges are convenient to install, carry and operate, durable in the open air and capable of defending against sunlight ultraviolet lights, and the service life of the building row hedges can be one time that of moso bamboo. Meanwhile, the building row hedges are connected in the clamping mode, work efficiency of the plastic steel row hedges during installation is more than five times that of original filament bundling, the architectural engineering aerial work platform has the advantages of being quick in installation, fixed in positioning, safe, reliable, easy to disassemble and the like, and work efficiency of the plastic steel row hedges during installation is greatly improved.
