Synchronous lifting and mounting method for high- and low-rise sunlight rooms

The invention provides a synchronous lifting and mounting method for high- and low-rise sunlight rooms. The synchronous lifting and mounting method includes steps of (1) assembling a low-rise sunlight room on the ground after assembling a high-rise sunlight room, and connecting the high-rise sunlight room and the low-rise sunlight room to form a whole sunlight room by temporary uprights; (2) adjusting lifting speed and keeping lifting the whole sunlight room to the designed elevation of the low-rise sunlight room; (3) welding the low-rise sunlight room in an counterpart manner; (4) cutting the temporary uprights between the low-rise sunlight room and the high-rise sunlight room; (5) adjusting lifting speed and slowly gradually lifting the high-rise sunlight room to the designed elevation of the high-rise sunlight room; (6) welding the high-rise sunlight room in a counterpart manner. By the synchronous lifting and mounting method for the high- and low-rise sunlight rooms, high workload in member assembling and welding can be avoided, construction efficiency is greatly improved, safety and quality risk can be reduced to the greatest extent, economic benefits are optimized, and hanging points are only set once.
