Description

Technical Field

[0001] The utility model relates to the technical field of steel bar component transportation construction of high-rise structures, in particular to a steel bar hook for high-rise structures. Background Art

[0002] A tall structure is a building or structure whose height is significantly greater than its base size, such as chimneys, TV towers, wind turbine towers, high-rise buildings, etc. During the construction process, the construction of tall structures mainly relies on the pouring construction process. First, the construction team will prepare the finalized steel formwork, which is pre-designed to ensure the accuracy of the structure. Then, these steel formworks are transported to the corresponding piers on the outside of the pool wall of the tall structure using a flatbed truck. After arriving at the designated location, the workers will carefully place the steel formwork against the pre-set support frame on one side of the pool wall. During this process, the position of the steel formwork needs to be carefully adjusted to ensure that it fits tightly with the pool wall, so that the tall structure can be firmly fixed on one side of the pool wall. Once the steel formwork is in place, the next step is to pour concrete into the steel formwork. The pouring of concrete needs to be carried out strictly in accordance with the construction specifications to ensure the structural strength and durability of the tall structure. After the concrete solidifies and reaches the strength required by the design, the workers will proceed to the next step, which is to remove the steel formwork. During the demolition process, special care was required to avoid damage to the newly cast tall structures. Finally, any local defects that might appear on the surface of the tall structures were carefully repaired to ensure the integrity of their appearance and functionality. Through this series of meticulous construction steps, the construction of the tall structures was successfully completed.

[0003] Although concrete is known for its excellent compressive strength, it has poor tensile strength. In order to overcome this weakness of concrete and improve the structural performance of tall structures, it is necessary to pre-place steel components in the steel formwork before pouring concrete. In this way, it can be ensured that the tall structures after pouring can meet the expected performance standards. In order to place the steel components in the three-dimensional steel formwork, a crane is needed to lift the steel components into the steel formwork. However, due to the high shape of the tall structure, the steel components need to adjust their inclination angle during the lifting process to ensure that they can be smoothly assembled in place. In order to achieve the purpose of adjusting the inclination angle of the steel components, the current method is to install an electric hoist on the rope for lifting the steel components, and adjust the inclination angle of the steel components by changing the length of the rope. However, in actual operation, the weight of the electric hoist itself may interfere with the lifting balance of the steel components, which is not conducive to the smooth lifting of the steel components. In addition, it is also a common problem that the rope is entangled in the electric hoist, which not only hinders the lifting operation of the steel components, but may even cause safety accidents. In view of these problems encountered in actual operations, the construction process of tall structures is in urgent need of improvement in the hoisting of steel components. In order to adjust the inclination angle of steel components and avoid interference with the hoisting operation of steel components, this is of great significance for improving the application value and reliability of tall structures in actual engineering.
