Compared with the prior art, the double-layer vertical hinged door for evacuation is designed on the premise that the consistency of the outer vertical surface is not damaged to the greatest extent, the outer layer of the double-layer vertical hinged door adopts design elements (materials can also be selected as materials consistent with the outer vertical surface) consistent with the outer vertical surface, and the consistency of the outer vertical surface effect is ensured; the inner layer door guarantees the airtight and watertight performance of the indoor environment for the conventional vertical hinged door, and the inner door and the outer door are opened in a linkage mode through specific gears, so that the outward evacuation opening function is finally realized. Specific: the invention is composed of an outer vertical hinged door, an inner vertical hinged door and a steering synchronous transmission gear system, all components are processed and produced in factories, only assembly construction is needed on site, no site welding is needed, and the installation workload is low. Meanwhile, the double-layer evacuation door is adopted to replace the traditional single-layer evacuation door, so that the consistency of the effect of the outer vertical face can be effectively ensured, and the problem that the appearance of the vertical face is influenced due to the fact that the traditional evacuation door of the full curtain wall vertical face building breaks the decorative line is solved. In conclusion, the curtain wall outer elevation effect consistency control method has the characteristic of effectively guaranteeing curtain wall outer elevation effect consistency.
