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 for objects that cannot be dismantled; Ancillary facilities that can be disassembled, using this construction method, still have the following problems: 1. The dismantling and assembly process takes a long time, which affects the construction period; 2. On-site assembly often leads to a decrease in the performance of the whole machine and affects the use effect
Mobile lifting equipment such as crawler cranes and wheeled cranes can move flexibly, and the lifting height can reach 50--80 meters, but there is also a limit to the ultra-high carrying capacity, and the lifting weight is generally below 10 tons; Larger its carrying capacity, on the one hand, the manufacturing cost rises geometrically; on the other hand, with the increase of hoisting weight and hoisting height, a large turning space is required for construction, and high-rise building construction sites generally do not have a lot of open space Therefore, mobile lifting equipment such as crawler cranes and wheeled cranes are not suitable for the overall hoisting of the three super-materials (lifting height, overweight, and ultra-narrow) on the top floor of super high-rise buildings.

Embodiment 1

[0036] The height of a certain project is 204m, the minimum unit weight of the hoisted object is 8 tons, and the lifting height difference is 214m. A 30t class super high-rise building top floor heavy object hoisting device is used, and 3 stabilizers are used. Stress cables apply 7 tons of prestress at the same time; make the angle between the stabilizer bar on the horizontal plane projection: 2*40°, and the angle between the stabilizer bar and the stabilizer bar on the horizontal plane projection line: 45°; use the cable There are 6 winds, so that the angle between the projection of the cable wind on the horizontal plane is: 5*20°, and the angle between the projection line of the cable wind and the cable wind on the horizontal plane is: 30°; start the peripheral hoisting equipment to make the hoist The hook on the block block, the hoisting balance beam to the lifting point, and the hoisted weight is tied and hung on the hoisting balance beam; then, the weight is lifted to an e...

Embodiment 2

[0038] The building height of a certain project is 125m, the minimum unit weight of the hoisted object is 15 tons, and the lifting height difference is 135m. A 30t class super high-rise building top floor heavy object lifting device is used, and 2 stabilizers are used. Stress cables apply 10 tons of prestress at the same time; make the angle between the stabilizing bar on the horizontal plane projection: 90°, and the angle between the stabilizing bar and the stabilizing bar on the horizontal plane projection line: 60°; use cable wind 6 root, so that the angle between the projection of the cable wind on the horizontal plane is: 5*22°, and the angle between the projection line of the cable wind and the cable wind on the horizontal plane is: 40°; start the peripheral hoisting equipment to lift the block The hooks and the hoisting balance beam on the upper floor are lowered to the lifting point, and the heavy objects to be hoisted are tied and hung on the hoisting balance beams; th...

Embodiment 3

[0040] The building height of a certain project is 70m, the minimum unit weight of the hoisted object is 14 tons, and the lifting height difference is 80m. A 20t class super high-rise building top floor heavy object lifting device is used, and 2 stabilizers are used. Stress cables apply 7 tons of prestress at the same time; make the angle between the stabilizer bar on the horizontal plane projection: 90°, and the angle between the stabilizer bar and the stabilizer bar on the horizontal plane projection line: 30°; use cable wind 6 root, so that the angle between the projection of the cable wind on the horizontal plane is: 5*24°, and the angle between the projection line of the cable wind and the cable wind on the horizontal plane is: 13°; start the peripheral hoisting equipment to lift the block The hook and the hoisting balance beam on the hoist are lowered to the lifting point along the guide cable, and the heavy objects to be hoisted are tied and hung on the hoisting balance ...

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 astate 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.
