While reducing the amount of high-altitude work and improving the safety factor, the installation quality and installation efficiency can be guaranteed.

[0108] In this embodiment, the membrane structure is innovatively applied to the building exterior curtain wall. A membrane structure curtain wall is added outside the traditional glass curtain wall to form a "double-skin curtain wall", which better isolates heat radiation and maintains the indoor temperature, saves 10% of air conditioning energy consumption, 4% of heating energy consumption, and about 5.6% of building energy consumption, thus meeting the relevant requirements of green and low-carbon construction. The present invention divides the vertical membrane structure curtain wall into modular standard units, completes the frame structure 100 and film processing and locking in the factory to form modular standard units, and only needs to assemble, hoist and adjust the standard units on-site, with high installation efficiency and good quality.

[0109] In this embodiment, the modular standard unit membrane structure is shaped by double-tension of a single-layer film, and the film material is split into 4 pieces and installed in one piece. When maintaining and replacing, the split film material can be directly replaced.
