[0002] Precast concrete panels are a type of construction material used in building and structural engineering. They are made by combining precast concrete with other materials to provide specific properties and functions, such as fire protection, thermal insulation, sound insulation, etc. These panels are usually manufactured in a factory and then transported to the construction site for installation, so that buildings or structures can be constructed and installed faster.

[0003] At present, the conventional construction method is to complete the erection of the load-bearing frame, fix the side beam formwork, and then hoist the composite slab. However, in the existing prefabricated building hoisting operations, it is often encountered that the shelf width cannot be guaranteed at one time when the composite slab is hoisted. After one hoisting is completed, it is necessary to use a crowbar to pry it again, which increases the lifting workload. Because the precast concrete composite slab is large and heavy, it is difficult to manually adjust the positioning and installation.

[0004] Therefore, the known installation and positioning methods of prefabricated concrete composite panels have the above-mentioned inconveniences and problems. Utility Model Content
