Lifting frame and construction method used for installing anti-floating anchor assembly indoors

The invention discloses a lifting frame and a construction method used for installing an anti-floating anchor assembly indoors. The lifting frame comprises a base disk (7), vertical pillars (10), a top frame (11) and a steel wire rope (12) with a lifting hook. The top frame (11) is provided with a fixed pulley (13). The base disk (7) is provided with a weight block (14), an anchor beam (15) and rolling wheels (18). The steel wire rope (12) is fixed through a rope clamping head (17) after bypassing the fixed pulley (13) and the anchor beam (15). The key step of the construction method is that an anchor string section is sunk by using the lifting frame and the steel wire rope (12), and connected with a hole mouth of an anchor hole in a butt joint mode. When the floor height of an indoor space is smaller than the overall height of the assembly, the anti-floating anchor assembly can be installed through the lifting frame and the construction method.
