Problems solved by technology

[0002] The top floor of super high-rise buildings (above 100m) generally needs to install auxiliary facilities such as central air-conditioning hosts, and its overall weight generally reaches 10-30 tons; it is used for lifting construction materials (within 10 tons) Light and bulk materials self-elevating or Internal climbing tower cranes, construction elevators and other ground-fixed conventional hoisting equipment cannot hoist the above-mentioned overweight objects due to the limitation of rated load-carrying capacity; For small-volume and heavy-weight projects, if the load-carrying capacity of the self-elevating or internal climbing tower crane is increased because of the need to hoist this part of the auxiliary facilities, the manufacturing and installation cost of the crane will increase geometrically, which is relatively higher than that of the entire building. uneconomical for engineering
Therefore, at present, the overweight ancillary facilities are generally dismantled, each component is hoisted in place, and then assembled. This method is only suitable for the ancillary facilities that can be dismantled, and cannot be hoisted fo

Abstract

The invention relates to a method and a device for lifting weights on the top floor of a super high-rise building, wherein the device comprises a stand, a fixed mast, a movable mast, a ball joint, a guy cable combined disk, a hoisting block, an amplitude-change block, a stabilizing bar, a guy cable and a prestressed drag line; the stabilizing bar, the stand, the guy cable combined disk and the fixed mast are utilized to form a stable support structure, and meanwhile, prestressing force applies to the guy cable and the prestressed drag line; when weights are lifted, the stabilizing bar is in a state with small stress or no stress and generates sufficient stability and safeguard; and a guideline resists transverse wind loads. The invention has a simple process method, and the device has reasonable structure, simple and convenient operation, small overall weight, flexible movement, convenient assembly, disassembly, entrance and exit, safe operation, low cost and short construction period, and can realize the integral lifting of overweight objects on the top floor of the super high-rise building, overcome the difficulty of the integral lifting of the overweight objects on the top floor of the super high-rise building which can not be finished by traditional construction elevators, tower cranes and traveling cranes, solve the difficult problem puzzling the technical field of construction and installation for a long time, and realize standardized and mass large-scale production.
