Description

Technical Field

[0001] This utility model relates to the field of high-rise building structure technology, and in particular to the tower crown structure of high-voltage areas in high-rise buildings. Background Technology

[0002] With the rapid advancement of urbanization, high-rise buildings are springing up like mushrooms after rain, becoming an important symbol of modern urban landscapes. In high-rise buildings, the setting of high-voltage zones has become a key aspect in order to meet their huge internal power demand. As an important component of high-voltage zones, the tower crown structure plays an irreplaceable role in ensuring the stable operation of the power system, improving the overall safety of the building, and optimizing space utilization.

[0003] At present, the tower crowns of high-rise buildings are located in areas of concentrated wind load. Many traditional tower crowns adopt closed solid structures or heavy decorative components, which can easily increase the overall load of the building due to their excessive weight, leading to increased construction costs. In addition, the wind pressure is relatively concentrated, and when the windward side is subjected to huge wind pressure, there is a risk of structural deformation. To address these issues, we propose a tower crown structure for high-pressure areas of high-rise buildings. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device combines a honeycomb aluminum core filler with a lightweight alloy steel frame to reduce the overall weight of the equipment and effectively reduce the overall load on the building. Utilizing the cross-shaped reinforcing ribs and reinforcing rings of the supporting frame, it can achieve efficient material distribution while ensuring the rigidity of the equipment. Furthermore, the reduction in the self-weight of the equipment structure can effectively reduce the foundation cost. This effectively solves the problem that many traditional tower crowns, which often use closed solid structures or heavy decorative components, are prone to increasing the overall load on the building due to their excessive weight, thus increasing construction costs. This device uses a three-layer pressure-distributing layer with a gradient pressure relief mechanism, combined with a ventilation hole array arranged in a diamond-shaped topological grid, to form a stepped airflow channel, which can effectively avoid wind pressure concentration. At the same time, the staggered arrangement of the bottom wind-resistant reinforcing ribs and the middle reinforcing ribs can effectively prevent the formation of eddies and reduce the amplitude of wind-induced vibrations.
